GEORGE G. GOING, Ol' HIDDLETOWN,

LESS TYPEWRITEB CORPORATION, 0F NEW YORK,

Application illed January To all whom, 'it may concern:

Be it known' that I, GEORGE G. GOING, a citizen of the United States, and resident of Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines,- of which the following is a. specification. My invention relates to typewriting or like machines and particularly to type actions therefor.

The main object of the invention, generally stated, is to provide an improved construction and arrangement of parts whereby the elements of each type action are functionally and structurally coordinated to ,facilitate printing in an improved manner.

More specifically stated, one of the objects of the invention is to provide improved and highly efficient type actions for printing without` producing the noise that ordinarily results from the operation of thetype actions. v

A still further object of the invention is to provide an'impiov'e'd and highly eiicient construction of the character specified in which the type actions are controlled from a standard keyboard with a single shift.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly `pointed out in the appended claims. j In the accompanying drawings, wherein likel reference characters indicate corresponding parts in the different views,

,Y its two keys.

Figure 6 is a view corresponding to Fig. 4 except that the type bar 1s shown moved to the printing position under the control of the other of its printing keys.

Figure; 8 is a detail view showing the preferred arrangement of the printing keys. The present invention is in the nature of an improvement on the construction disclosed in my co-pending application, Sr. No. 665,290, filed September 28, 1923. The improvements over the prior construction are intended in the main to render the operation of the type action more efiicient, reliable and uniform throughoutythe system.

In the accompanying drawings I have" shown only so much of a typewriting machine as is necessaryto arrive at an understanding of my invention in its embodiment therein. I have -shown my invention applied to a machine which, as to features outside of my invention, may be similar to that formerly known commercially as the noiseless typewriter.

Asin the construction disclosed in my said co-pending application, I provide in the present instance a machine having a standard keyboard of four banks of keys, each type bar carrying four types and being operated by either one of two keys. Each pair of keys actuate a single front stroke type bar in a substantially noiseless manner to normally selectively print from one or another lower case type on the type bar, depending on which of the two keys is actuated, or .to selectively print from one or another upper case type on the same type bar after a relative case shift has been effected beftween the platen and type bars.

In the present embodlment of my invention the frame of the machine may be said to include a base 1, and so-called front plate or member 2 on which various working parts of the machine, including the type actions, are supported. It will be understood that barsare arranged in a substantially horizontally disposed are front of and around the printing point as a center, so

` that each type bar moves but ashort distance in a radial` lane to the common printing center as in t 1e construction disclo-sed in my said companion application. The controlling means for each type bar, with the possible exception in some instances of the key lever therefor, moves in the same plane as the plane of movement of the associated type bar or as close to and parallel with such plane as the assembled parts will permi j t With thefforegoing general statement I will roceed to describe a single type action, it belng understood that all actions are alike or substantially so, except that they are mounted in di'erent planes Vthat radiate from the printing center. The description of one type action applies to the others.

Each type action comprises a at substantially horizontally disposed type bar or type vcarrying `member 3 provided with a plu# rality of type heads 4 and 5 fixed thereto. The type head 4 has a lower case type 6 and an upper case type 6a, whereas the type head 5 has a lower case type 7 for printing a different character and a companion upper case type 7, the printing faces' of the types on the two blocks being arranged in convergment by two arc-shaped guides a and a.

in planes. Each type bar is guided against si ewise displacement in itsprinting movehaving Aradial slotsI in which the type bars move. Each typey bar is supported by va palr of links 8 and 9 pivoted respectively at 10 and 11 to the type bar at different points in the length thereof; the link 8 being pivoted to the type bar nearest the rear or type-carrying end thereof. The link 8 extends as one -continuous member to the pivot 10 on one side of the type bar and has a thin sheet metal plate 8% spaced apart from the body of the link butrivetednthereto. This plate 8a connects with the pivot 10 on the opposite side of the type bar. The links 8 and 9 are mounted to swing'respectively on pivot ins 12 and 13 inthe movement of the type ar from normal to printing position. In the present construction the pivot pin '18 always remains xed during the travel of the type bar to printing position, but the ivot pin 12 is arranged to ,be displaced from normal position, as shown in Fig. 6, during the travel of the companion type bar undery Ithe actuation of one of its keys, as will hereinafter appear. The pivot pin 12 is mounted on a controlling member 14 which in the present instance is in the nature of a bell crank lever pivoted at 15 on a headed piyot in secured to a stationary supportf ing mem er or arm v16. This supporting ed. From certain aspects of my invention any suitable means fonelfectingv an adjustment of the member 16 on ythe bracket 17 to different set positions may be provided. However, I prefer to employ the adjusting means disclosed hereinv as they have proved eflicient in practice. The same is likewise true of other adjusting \means to Vbe described. The adjusting means for the arm 16 as best dshown in Figs. 1, 2' and 8 comprises an eccentric 18 formed with an angular orl hexagonal head"19 by which the ec- Lcentric may be turned on a headed pivot pin 20 riveted to the hanger 17. The eccentric 18 is received in an inclined slot 21 in the supporting arm 16 intermediate the ends thereof. A second similar adjustable eccentric 22 is carried on a pivot pin 22a riveted to the hanger 17'a11d is received in a slot 23 in the arm 16 near the upper end thereof. A supporting pin or stud .'24 is kfixed on the hanger or bracket 17 and received within an inclined slot 25 in the arm 16 near the lower end thereof. yThis slotis inclined at about 19 degreesv to the horizontal and extends lengthwise 'at about right angles to the length of the slot 21. The part of. slot 23 in which the eccentric 22 is situated is parallel to the slot 25.k The reasons forv these angles will appear hereinafter.. These adjustable means are effective to give the lower end of the arm 16 an adjustment in substantially any direction in the plane of said arm and to effect a corresponding adjustment of the pivot 15 and the` parts carried thereby including the pivotal center 12of the type bar supporting link 8. These adjustments aid 1n effecting a proper alignment of the type bar. In order to laid in preventing an accidental displacement of the arm 16 from the position to which it has been adjusted, I provide a binding washer 26 that bears vagainst one side of the arm 16 near the upper end thereof. The stem of a headed screw 27 passes through this .washer and through the slot 23 in the arm 16v and is received at its threaded end in a tapped opening in the-hanger 17. By tightening this screw 27 the arm 16 is firmly held in its adjustedposition against a side of the hanger or bracket l17.

It has been explained that a separate supporting bracket or hanger 17 is provided for each type action. These brackets are radially disposed around the printing point; means being provided whereby/each bracket together'with the parts of the 'type 'action carried thereby may be lindividually introduced into and removed from the vmachine as a separate unit, and may receive anindividual adjustment radially toward "and I width terof the supporting link /ceived in aradially disposed slot in the topA of the front plate'2 of the machine frame. A dependin projection 29 at the forward end of each )racket is received in a circumferential groove 30 in a, screw`31 threaded into a tapped openingl in the front plate 2. The rear depending end of each bracket 17 is slotted at 32 (see Fig. 7) to receive the web 33 formed at the forward transversely slotted edge portion of a support-v `ing member 34 secured to the base of'the machine. The forward edge of the member y 34 is segmental in form corresponding to the arrangement of the set of brackets 17 at the lower ends thereof and has inter-dental openings 35 therein; each-corresponding in to\ the thickness of the associated bracket 17T This construction vprovides a {i1-1n interlocking support between each bracket and the member 34 which holds the bracket against movement in every direction except that of its radial adjustment, effected by the companion screw 31. A screw 28a coacting with a clamping plate 28b holds the companion bracket firmly in its adjusted position and enables the bracket with the parts carried thereby to be readily detached as a separate unit when desired.

The pivot 13 for the supporting link 9, as previously stated, remains fixed at all times during the movement of the associated type bar. However, I prefer to make the pivot 13 independently adjustable to different set positions to vary the pivotal ccn- 9 in order to further aid in obtaining proper alignment of the associated type bar. In the present construction I attain this end by mounting said pivot 13 at the lower end of an adjustable supporting member, arm, Vorlever '36, arranged-'j on the opposite side of the bracket 17 from that which carries the arm 16; the member 36` being pivoted intermediate `its ends to the bracket at 37. The upper end of this supporting member 36 has a slot 38 therein that extends longitudinally in the -general direction of the length of said memv ber, and in whichan eccentric 39 is received.

This eccentric 39 corresponds in construction to the eccentrics 18 tand 22 but unlikeV them is mounted on a headed screw 40- threaded into a tapped opening in the bracket 17. An adjustment of the eccentric 39 on the screw 40 is effective to turn-the supporting arm 36 in one direction or another around its pivot 37, effecting a corresponding adjustment of the pivot 13` for the supporting link 9. By tightening the 'screw 40 the eccentric 39 and the arm 36 are firmlyheld in adjusted position. .v

It should be understood that all of the adjusting eccentrics 18 and 22 are constructed and mounted in the same manner on the bracket 17; that each of said eccentrics as well as the eccentric 39 is provided with a suitable head, suchas the hexagonal head 19, for co-operation with a suitable wrench or tool by which the companion eccentric may be individually adjusted; and thateach eccentric 18 and 22 is held friction-tight in itsv adjusted position between the head of its pivot lpin and the side face of the supporting bracket l17. When the arms 16 and 36. are once adjusted for purposes of aligning the com )anion type bar, such arms remain fixed, being thus held by the adjusting means and the clamping screws 27 and 40. The use of these adjustments will be explained in detail hereinafter.

Each type bar 3 is operated selectively by two keys, one of which automatically brings the upper and the other the lower pair of types 011 the bar to printing position., For` lack of room in Figs. 1, 4 and 6, these two keys are there shown in adjacent banks, but in practice I prefer the arrangement indicated in Fig. 8 where keys 41 in the4 second bank and 42 in the fourth bank are connected to one type bar, and keys 41n in the first bank and 42l in the third bank to another type bar. In moving a type bar to printing positionunder the actuation of the key 42, the type 7 will follow a curved path indicated substantially by the dotted line b, if the parts have been properly adjusted. the type bar is moved under the actuation of the key 41 the type 6 will follow a curved path -of the general character indicated by the dotted line 0. These curves are more nearly uniform, although they are oppositelydisposed, than in my prior application. The means by'which the paths of movement of a type bar are controlled include in part features which have. been described including the bell crank lever 14 by which the pivotal center 12 of the supporting link 8 may be' shifted back and forth from the Fig. 4 to the Fig. 6 position. I will now describe in detail how each type bar is controlled from its two printing keys,

The key 41 is carried by a key lever 43 fulcrumed at 44 in the base of the machine and provided with an individual returning spring 45. connected at one .end to a depending arm 46 on saidkey lever, and connected at its other end with a bar 47 that extends beneath all of the key levers and is adjustabl;Y mounted by suitable means in the base of the machine. The key lever 43 is detachably connected to a link-48 by a pivot 49 carried by said keylever and received in an opening in the lower end of said link. A

side-bearing spring plate or clip 50 is lpiv-v oted at 51 to the companion'key lever and b ears. laterally at itsy free end against the link 48. This clip holds the link connected On the other hand, when v clip is in the dotted line to the lever when the cli is in the eRective full line position, an enables the link to be detached from the lever when the osition shown in Fig. 1. The upper en of the link is pivoted at 52 to an actuating member, sublever or lever arm 53, pivoted at 54 on the right hand side of the bracketl 17. This lever is extended rearwardly beyond its pivot to form a secondlever arm 55 whichv constitutes one member of a controlling toggle. The other member of this toggle is a link 56 pivoted at one end, at 57, to the member 55 and at its other end, as at 58, to one arm of the bell crank lever 14.

In orderto limit the movement of the toggle member` 55 and the parts connected therewith in both directions, I provide an opening 59 in said member 55 to receive a stop pin 60 fixed to and projecting ylaterally from one side of the bracket 17. This stop pin co-acting with one side wall of the opening 59, as shown in Fig. 1, will limit the return movement of the member 55 and the parts connected therewith. This prevents the toggle 55-56 in its return movement from breaking beyond `the substantially straight line normal position.y The effect of maintaining the toggle in the substantially straight line position isto hold the pivot 12 quiescent in the position shown in Figs. 1 and 4, when the type bar is moved to printing position' by the actuation of the key 42, as will hereinafter more clearly7 appear. 4 However, the depression ,of the key 41 results in moving the meniber 55 to the position shown in Fig. 6, where the opposite side wall of the opening 59 co-acting with the stop pin 60 limits the movement `of said member 55 and the parts connected therewith, including the key 41. This depression of the key 41 results in breaking the toggle from the-substantially straight line holding position shown in Fig. 1 to the operated position indicated in Fig. 6, thereby lowering and moving forward the pivotal center 12 of the type bar supporting link 8, to change the path of movement of theftype bar to the printing position. The proper positioning of the pivot -12 in the Fig. 6 position andx the holding of it in such position by the toggle'is effected before the vfinal printing movement-of the type bar takes place.

The other printing key 42 of the typeaction shown is carried by a key lever 61, constructed, pivoted and individually spring returned, like the key lever 43 previously described. The keyv lever 61 is connected to a link 62 in the same manner that the link 48 is connected to itskey lever 43, and

l has its upper end pivoted at 63 to an actuating member or sub-lever 64. Said sublever is arranged at the opposite side of the hanger 17 from the lever arm 53, and is 1s pivoted at 70 on the left hand side of the I bracket 17, and is bent or off-set laterally to form a yoke portion 71 above the bracket and is thence bent downward to form a lever arm 72 on the left hand side of said bracket and overlying the lever arm 55, for purposes which will nowA appear.

It will be understood that after each breaking of the toggle 55-56 from the Fig. l to the Fig. 6 posltion by-an actuation of the key 41, the returning spring 45 for said key is intended to return it to normal straight line position when the operator releases the key. However, it may happen at times that the toggle 55-56 has not completely returned to the substantially straight line osition before an actuation of the type bar y the other key 42 takes place. It is in order to rectify the position -or insure the complete return of the toggle, and to thus maintain an accurate positioning of the .pivotal center 12 in the Fig. 1 position, that I provide the lever 69-7 2 operating in the manner described. Thus it will be understood from a consideration of Fig. 4 that a depression ofthe key 42, as indicated in dotted lines in this gure, will, through the intermediate train of connections 62, 64, 65, 67 and 69, lower the arm 72 to the dotted line position. If the toggle 55-56 had not been fully returned after the preceding operation of thev type bar by the key 41, then the member 55 will extend in the path of the arm 72, and as the latter is moved down to the dotted line position in Fig. 4 under the actuation of the key 42, the member 55 will be :Eorcedto the limit of its return movement, or until it coacts with the stop 60 in the Fig. 4 position. This occurs before the type bar reaches the printing position under the action of the key 42, and insures the proper positioning of the pivotal center l2 and insures that a proper imprint of the type atthe printing point will result.

Thus far I have described the means by which each type bar is individually guided or. controlled in its movement to travel in one curved path or another to a common printing center, to cause one or another typeV ey A auraisv governing means having a momentum accumulator, said governing means being arranged to decelerate the final printing movement of the type bar and totranslate into pressure against the platen the kinetic energy of the accumulator. It is-dueto vsuch means, combined with the parts previously described, that an im rint may be effected in substantiallyA a noise ess manner.

v In the present construction, operating motionis transmitted to each type bar from both of its printing keys through the above mentioned single trainof drivin means to actuate each type bar with a su stantially uniform touch from both its keys and Vto provide a uniform, or substantially uniform,

touch on the keys throu hout the system as will now be more clear described. This, it may be here remarke is regarded as an important factor of the present invention.

It has beenex lained that the independently o erating everarms 53 and 64, forward o their common pivot 54 are of uniform character and are mounted to move in parallel planes. A main driving lever 73 is lpovided for each type action, this lever ing pivoted at 74 on the associated bracket 17. Referring to Figs. 5 andn, it will be understood that in the present instance, I

construct each of these levers from two cor-.

res 'ondingly shaped members spaced apart an held together in spaced relation by suitable means, such as shouldered rivets 75 and 76 and other'means to b'e described. A- headed bushing 77 is seated in an opening in the bracket or hanger 17 and held in place therein by riveting one end of the bushing at 7 7 a. The pivot pin 74 is received and turns in the i bushing 77 and is riveted at its reduced ends to the companion members which constitute the lever 73. Each member of the lever 73 is provided with a forwardly extending arm 78 having aninwardly bent lug 79,- said lugs having an edge-to-edgebearing one against the other. These lugs constitute a contact that is adapted at the limit of the operating movement of the lever 7 3 to bear upwardly against a suitable stop structure. Such stop structure, in the present instance, comprises -a thin metal segmentally shaped contact strip 80 held against a correspondingly shaped pad 81. Said pad is fixed in or on a metal frame 82 secured t0 the frame of the v machine, and having a contour that conforms to the pad. Rearwardly 'extending parallel arms 83 on the driving lever 73 each preferably has a curved contact or rolling tread 84'. A curved or rolling tread 53l on the overlying lever 53 co-acts with one of the treads 84, whereas the corresponding` rolling tread 64 (Fig. 6) on thefoverlying lever 64 co-acts with the other tread 84 on the driving lever. A depending link 85 is pivoted on the rivet 76 of each driving lever 73 and is forked at its lower end to co-act with a segmental universal bar 86 which train of driving connections including motion governing means having a momentum accumulator. Such means are effective to transmit a forward thrust tothe type bar in a uniform manner whether actuated by one or the other associated keys 4l and 42. This train of connections includes a tog le comprising a double toggle link 89 made up of two correspondingly shaped members con nected together but maintained spaced apart by a shouldered rivet 90. The forwardend portions of the members of this double link 89 extend on Aopposite sides of the type bar and are connected thereto by the pivot 11 which also connects the su porting link 9 to the type ba-r. A secon double toggle member 91 is made up of two correspondingly. shaped united parts, which are maintained spaced apart. This double member is pivoted at 92 to the forward end of the link 89 and extends on opposite sidesof the bracket 17 and is su ported to turn on a fixed pivot 93 carried by the bracket. A single link or lever arm 94 is connected at one end by the pivotl 88 to the upright double arm 87 of the main driving lever. The link 94 extends between the two members which constitute the toggle member 91 and is pivoted thereto at one end, as at 95, and it moves the toggle 89--91 to the substantially straight line osition represented in Figs. 4 and 6, to app y printing pressure along the straight line of the toggle. Rigid.- ly attached to the link or lever arm 94 is a comparatively heavy weighted member 96 which normallyl rests on a segmental supporting pad, 97 and serves as a momentum accumulator for the actuating toggle 89, 91 when the latter is actuated by the main driving lever 73. After the 4depression of a printing key has been arrested, the momentum of the accumulator 96 .will continue its movement to impart its energy to the toggle in order to complete the movement of the toggle members to the substantially .straight line position, thereby completing the printingstroke of the type bar. It will be seen therefore that this momentum accumulator 96 is adapted to supply the final energy necessary .to straighten the toggle 89-91 when the type bar has substantially reached the printing position. l A contractile spring 98 is connected at one end to the bracket 17 and at the other end to the rivet 76 on the driving lever 73, and serves to returii the lever 73 and the parts connected therewith to the normal, Fig. 1, position after each actuation; the key lever being independently arrested in its return movement by a padded stop d. In arrangement and principle of operation the toggle mechanism just described is substantially the same as has been used heretofore in the noiseless typewriter, but some detail changes have been made to adapt it to the present mechanism.

In Fig. 6 the key 41 is shown in its extreme depressed position and the type 6 is pressed against the laten. In Fig. 4 the type 7 is pressed against the platen, and the corresponding or extreme depressed position of the key 42 is shown by broken lines. In both fi res the last part of the stroke of the type ar was effected by the momentum of the weight 96 which has moved the arm 83 somewhat out of contact with the arm 53 or 64. In Fig. 4, therefore, the lever arm 72 had completed its stroke and assured the position of arm 55 and pivot 12 before the type 7 reached the pla-ten; arid in Fig. 6 the arm 55 had completed its stroke and thus brought pivot 12 completely to its lower position before the type 6 reached the platen.

The platen carriage and case shift mechanism are more or less conventionally-represented. As shown in the present example, the platen 99 is carried by a suitable carriage 100 supported through intervening ball bearings (Fig. 4) on a case shift rail 101 to travel from side to side of the machine. The case shift rail is guided by links 102 and is mounted to receive, together withthe carriage and platen, a single upwardly directed case shift movement from the normal position, represented in full lines, to the upper case position. The platen is shown in the last named position in dotted lines in Figs. 4 and 6. Any suitable means may be employed for this purpose. The conventional representation shown in the present instance, includes a case shift key 103 and a lever arm 104 carried by a rock shaft 105.

The latter has two rearwardly extending arms each pivoted at 106 to a link 107, which in turn is connected at its upper end 108 to the case shift rail 101. In Fig. 4 I have shown a lower case type 7 on the type block. 5 at the printing point under the action'of the key 42, whereas in Fig. 6 I have shown a lower case type 6 on the type block 4 at the printing point under the action of the key 41. When the platen 99 is shifted to the upper case position, then one of the upper case types 6a or 7a will be selectively moved to the printing point, depending on which of the two associated keys 41 or 42 is actuated.

In order to actuate the type bar 3 and bringit to the position shown in Fig. 6,

'73 gives a variable acceleration to the motion of the latter andalso provides a lost motion connection between the levers 53 and 73. This lost motion is brought about when the motion of the lever 53, and the key 41 by which it; is actuated, are brought to rest at the end of their stroke, as shown in Fig. 6. At this time the driving lever 73 and the parts connected therewith, including the type bar, are permitted to continue their operation independently of theA lever 53, and under their own momentum, to eect an imprint without the impetus of the actuated key 41 and the parts connected therewith at the nal portion of the printing stroke. The motion thus transmitted to the type bar is in the nature of a thrust exerted through the toggle members 89 and 91, pushing thev type bar to the printing point, and by the final expenditure of energy apply a powerful printing press. The printing operation of the type bar by an actuation of the key 4 is accompanied by a displacement of the pivotal center 12 of the supporting link 8, as shown in Fig. 6. This is accomplished by breaking the toggle 55-56vv from its substantially straight-line position,

shown in Fig. l, to the position,represented in Fig. 6, due to the actuation of `the lever arm 53 with which the toggle has direct mechanical connection. This results in turning the lever 14 on its pivot 15 from the Fig. 1 to the Fig. 6 positiony as hereinbefore explained, thereby changing the position of the pivotal center 12 of the supporting link 8 and causing the type bar to travel through a different curved path from that which it follows when actuated by /the'key 42, as indicated by a comparison .of the dotted lines b, c in Fig. 1.

An actuation of the type bar by the key 42 produces a like movement of the singletrain of connections from the driving lever 73 to the type bar. In this instance, however, the toggle 55-56 remains at rest in the substantially straight-line position, as indicated in Fig. 4, thereby holding the pivot 12 fixed against movement while the link 8 turns thereon. This results in the type bar moving in a curved path indicated substantially by the dotted line b in Fig. 1, to print from one or the other of the types 7 or 7, depending on whether the platen is in the lower or upper case position to receive the impress from the corresponding type.

. The adjustments for the pivot pins 12 and 13 of the links 8 and 9 respectively are novel and are of such character as to enable the following results to be obtained:

(a) The type bar can be so adjusted when Fig. 4' position in its Fig. 6 osition as to cause the type block 4 proper y to enter the center guidethat is to say, the rear end of the type bar can be adjusted up and down so as tobring the type 6 exactly to the printing point;

(b) The typebar can be adjusted angularly so as to set the types 6 and 6a on their feet;

(c) The type bar can be adjusted so that whenin its Fig. 4 lposition the lowertype block 5 is at the proper height up and down to enter the center guide and to bring the type 7 exactly to printing position, and

` this adjustment can be made without in any wise disturbingv the adjustment formerly made with respect to the type 6. -In other words, the up and down'position of the rear end of the type bar can be adjusted for the without. disturbing a previous adjustment made for the Fig. 6 position, thus compensating for any manufacturing error in the relative positions of the two type blocks on the rear end of the same type bar. One of the features which makes this result possible resides in the fact that the slot 25 and the rear part of the slot 23 in the support 16 are parallel to each other and are perpendicular to the line drawn through the centers of the pivots 12, 15 and 10 when the `type bar stands in its Fig. 6 position. In the particular `machine shown in the drawing this line 12, 15, Fig. 6, makes an angle of about nineteen degrees with the vertical, and the longitudinal axis of each of the slots 25 and 23 is at an angle of about nneteen degrees with'the horizontal. It results from this construction that when the eccentric 18 is turned the effect is to slide the support 16 bodily rearward atv a downward inclination of nineteen degrees, or forward at an upper inclination-of nineteen degrees.V In other words, the adjustment of the pivot 15 is perpendicular to the radus 15, 12 of the lever l14 when said lever is lin its Fig. 6A position. The result is that for the small adjustment that is required, said adjustment being perpendicular to the radius, the pivot^-12 receives practically no up and down motion due to-the adjustment. This adjustment therefore, namely, the adjustment by turning the eccentric`l8`, has no effect on the position of the type 6 asshown in Fig. 6. Turning to Fig. 4, howeverkit will be seen that the adjustment just referred to will regulate the up and Vdown position of the type block 5 and typel 7 when these are in printingposition. In this figure the pivot 58 occupies about the same position that the pivot 12 occupied in Fig. 6 and the radius 58, 15 is at an inclination of about nineteen degrees with the vertical. The effect of adjusting the point 15 in the manner above described is therefore to rock the lever 14.about the pivot 58 as a center, with the result that the pivot 12 of the link the type 7 ycan be regulated by this adjustment independently ofthe printing position 'of the type 6.

In order to regulate the up and down position of the said type 6, the eccentrics 22 and 39 are used. Referring to Fig. 6 an adjustment of the eccentric 39 moves the plvot 13 lengthwise of the link 9 one way or the other. An adjustment of the eccentric 22 moves the pivot 15 in the direction of the length of the linkv 8. If, for example, the type 6 is too high when first brought to the Fig. 6 position it canbe lowered either by adjusting the pivot 15 downward or by adjusting the pivot 13 upward. When 1t has been broughty to the proper height by one or the other of these means it may be found that the type isnot on'its feet; that is to say, that the plane of the types 6 and 6a is not exactly tangential to the platen at the printing line. If, for example, the type bar is found to be tilted backward, bringlng the type 6 too close to the platen, this can be corrected by lowering both of the pivots 15 and 13, the pivot 13 being lowered more than the pivot 15, in such relation that the adjustment of the type bar would be' in the nature of a swinging of the front end of the type bar downward about the type face 6 as a center If the error was in' the opposite direction the adjustment would of course be the reverse.

In practice the type bar is first adjusted ycorrectly to the Fig. 6 position by adjustments at 22 and 39. Afterward the type bar is brought to the Fig. 4 position and adjusted by means of the eccentric 18 to bring the type 7 and type block 5 into correct u and do/wn position. As has been exp ained, this does not disturb the previous adjustment made with respect to the upper types.

It will be seen that the adjusting means for each type action are located at the forward .and upper portion thereof where amplewidthwise space is provided betweenk actions and ready access to` the adjusting means from above may be had.

The construction and relative arrangement of the parts of each type action is such that near the rear or type-bearing end of the action the mechanism is thin as viewed from above, and even at its point of maximum thickness which is more remote from the center from which the type actions radiate,

each action has a'thickness of only about of an inch, thus enabling twenty-two type actions -to" be conveniently brought into a comparatively small widthwise space without unduly crowding them, and to effectively' print in substantially a noiseless manner, the requisite number of characters with the aid of a standard keyboard and a single case shift. Moreover, the construction is such that it readily lends itself to the employment of more than the usual eighty-four Characters when desired, and provides a light, fast and highly efficient type action with a substantially uniform touch on the printing keys throughout the system.A

It will be seen that in the present construction the supporting and guiding links 8 and 9 merely act as such at all times, the driving operation of the type bar being never effected through said links; and that whether the type bar be driven by the actuation of one or the other of the keys 41 or 42 such driving operation as such is effected independently of said links and always through-the separate and distinct single driving train fromand including the lever 73 which exerts at all operations a thrust on the type bar to move it to printing position always in a uniform manner.

It will be understood, moreover, that th pivotal support forl the link 9 is at all times maintained fixed during the printing operation whether operating the type action from the key 41 or 42 and that the present construction as a whole provides a type action which has a light touch, is speedy in operation, and results toa high degree in a simple, uniform, accurate, noiseless .and reliable printing operation that may be controlled by a standard keyboard.

In addition to the type bar guides a and a', hereinbefore referred to, I prefer to employ a suitable type bar center guide, not shown.

The linkage by which the type bar is guided includes a number of joints or pivots, all of which are free moving joints; but notwithstanding, it is found in practice that the types strike the paper in good alignment. The platen and carriage are mounted and controlled the same as in the well known noiseless typewriter, and said platen yields rearward atv each imprint of a type, something like five one-thousandths of an inch.

Due to the particular manner in which the type bar is moved while the type is acting on the paper, I obtain increased manifolding effectiveness in the present machine.

As the type comes in contact with the paper before the final straightening of the type bar such type rolls or kneads its way on the paper to final printing position. This kneading effect isI due to the manner in which the type bar is controlled by its supporting, and guiding linkage. When the type face first presses against the paper it does not contact quite squarely, the upper part of the type being slightly in advance. The bar is then caused to rock or cant downward so as to bring every portion of the type face successively under the pressure of the driving toggle. In thus slightly changing the angular relation of the print.

ing face of a type while it is making the impression, I obtain a rolling or knea'ding of the carbon against the paper, thus producing a stronger and better carbon imprint.

While I have described in considerable detail the constructional form of the various memberswhich go to make up each type action, I am aware that various changes may be v made in the construction, and that certain parts thereof may be em loyed without others, Withoutdeparting rom my invention as it is defined in the accompanying claims. However, the form of construction shown and described has proven reliable and efficient in use.
