To (L7/Z whom, t may concern:

Be it known that I, HERMAN HOLLERI'IH, of iVashington, District of Columbia, have invented certain new and useful Improvements in Adding and Recording Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference boing had to the accompanying drawings, formino a part of this specification, and to the figures of reference marked thereon.

My invention relates particularly to that class of adding-machines in which a single series of keys controls successively a number of sets of indicating and registering wheels dealing, respectively, with units, tens, hundreds, lc.; and it consists in certain novel improvements relating to the indicating and adding mechanism proper, as Well as to mechanism for recording the indicated numbers, which will be first described at length, and thon pointed out particularly in the claims at the close of this specification.

ya small rack-bar 7.

Similar numerals of reference in the several figures indicate the same parts.

The machine consists of two side frames 1 l, Fig. 1, connected together by two cross-plates 2 and 3. (Shown in cross-section in Fifr. 2.) Sliding in suitable grooves in these crossplates are a series of actuators or actuatingbars 4t, the number of these actuating-bars depending upon the capacity of the machine, one such bar being required for each order. l will hereinafter refer to these bars as unitsbar, tens-ban hundreds-bar, dsc., according to t-he position of the bar. These actuating-bars are normally held in position by the pawls 5. Below each bar there is a spring G, one end of which is secured to a pin projecting downward from the forward or outer end of the bar, the other end being secured to a fixed point of the main portion of' the machine. Mounted alongside of each actuating-bar is cause of its functions may be termeda tenscarrying bar, is capable of a limited motion alongside of the main actuating-bar 4, such motion being equivalent to one unit, or, in the present instance, two of the rack-teeth S. The rack-bar 7 is normally held against the tension of the spring 9 by the pawl 10, secured to the actuating-bar and engaging the pin 11, secured to said rack-bar 7. The construction of the Inain actuating-bar and rack-bar is more particularly shown in Figs. 3, 4, and 5. A fiat spring 12 engages a projection from the pawl 10 to hold the same normally depressed. Pawl 10 is formed with a projection 13, extending sidewise, as shown more particularly in Fie. 5. Above the rack-bars 7, Fig. 2, and extending from one side of the machine to thc other is a shaft 1a. Loosely mounted on this shaft are a series of pinions 15, engaging with the teeth 8 of the rack-bars. Mounted alongside and secured to these pinions are the numbered wheels 16 and the tripping-pins 17, Fig. 5. These tripping-pins 17 are so arranged that as the pinions 15 rotatetheyengage with the projections 13 of the pawls 10,

so as to release the pin 11, Fig. 3, which allows the spring 9 to Inove the rack-bar 7 forward a distance equivalent to two teeth. The relations of the numbered wheel 1G, trippingpin 17 and pawl 10 are such that the pawl is tripped as the numbered wheel of the next lower order passes from 9 to O.77 The shaft 14 is held at its ends in the arms lS,whieh are pivoted on suitable pivots 19, as shown'in Fig. 9. Secured to these arms are the projections or cam-rollers 20,whieh engage with and are operated by the cam-bars 2l and Q2. (Shown in Figs. l, 7, and S.) These cam-bars 2l and J2 are mounted in the cross-plates 2 and 3, Figs. l and 2, and are secured by the links Q3 to the reset-levers 24. These resetlevers are secured to a shaft 25,which is mountA ed in the main plates l l.

At a convenient point the reset-levers 24- are joined by a bail 2G, as shown more particularly in Fig. l. Springs 27 are secured to these reset-levers 24 for the purpose of keeping them in their normal position, as shown in Figs. 7 and S. The cam-roller 20 and the cam-bars 2l and 22 operate in such way that as the reset-levers 524 are drawn forward the shaft 14, with its pinions and numbered wheels, are lifted, so that the pinions .l5 are disengaged from the rack-teeth 8, the pinions being held securely in their elevated position by the fixed rack-fingers 2S, Fig. 2. A series of these rack-fingers is secured to a suitable frame-piece 29, as shown in inverted plan view, Fig. o'. This frame-piece 29 is secured to the main frame-plates l, as shown in Fig. l.

Secured to the cross-plate 3 is a stop-block 30, Figs. l and in which there, are nine grooves at right angles to the actuatingbars 4 for accommodating the stops or stop-bars Si. These stop-bars are capable of a longitudinal motion. The arrangement of one such stop-bar is more particularly shown in Fig. lO. Each stop bar is provided with notches 32, which when the bars are in normal position allow the projections 33, Fig. 2, of the actuating-bars 4 to pass freely. lf, however, any such stop-bar 3l is moved longitudinally, it will arrest the passage of any of the actuating-bars 4. Connected to these stop-bars are depending cams 34, the construction of which is shown in Fig. l0. The key-levers are mounted loosely on a shaft G7, Fig. 2, secured to the side frames. At the forward ends these key-levers are provided with suitable keys numbered from O to 9, as shown in Fig. l. The rear ends of these key-levers are provided with camsurfaces 3o', Figs. 2 and lO, which engage with and operate the cams 34- and move the stopbars 3l longitudinally against the tension of springs 37.

At the forward end of the actuating-bars 4 are the rack-teeth 3S, which mesh with the pinions 39, loosely mounted on the shaft 40, Fig. 2. Secured to the pinions 39 are the num bei-ed wheels 4l, which show to the operator, through a suitable window in the casing 42, Fig. l, the number added, enabling the operator to note any errors. These pinions 39 remain constantly in mesh with the rackteeth 13S, and as the actuating-bars 4 move forward numbers are shown on the wheels 4l from O to 9, according to the forward motion of said bars 4.

As before stated, the actuating-bars are held against the tension of springs 6 by the pawls 5. These pawls are held in normal position by the springs 43, Fig. 2. llelow and in front of the projections 44 of the pawls 5 and extending from one side of the machine to the other is the tripping-shaft 45. This tripping-shaft 45 is more particularly shown in Fig. ll and is provided with a series of pins 4G, arranged spirally or helically, as shown. The tripping-shaft 45 is mounted at its ends in the arms 47, which are pivoted to the stop-block SO, as shown in Fig. l. A bar 4S rests across all the keys, except the ono which stands for Zero, as shown more particularly in Fig. ll, and is secured at its ends to links 49, loosely mounted on the shaft (.37. The ends of this bar 4S are also connected by links 50 to the arms 47. From this construction it will be noted that the depression of any key from l to 9 will raise the trippingshaft 45, Figs. 2, 7, and 8. The result of this is that, depending upon the position of the tripping-gills, one or another of the pawls 5 will be raised, so as to disengage the particw/ lar bar 4. f

Mounted on the trippingshaft t5 a spring 52, one end of which is connected to the arm 47 and the other end to ihc tripping-shaft 45. The tension of this spring is to hold the shaft through the ratchetwheel 53 against the rctaining-pawl 54. (Shown more particularly in Fig.S.) This retaining-pawl is constructed with a laterally-projccting arm 55, passing through the opening in the arm 47, as shown in Figs. l, 7, and ll.. A pawl 5G is secured to a block 57, attached to the cross-plate 3, Fig. 2. lt will be noted that if the trippingshaft 45, by means of any keyfrom l to 9, is raised as it is retracted by the springs 5S, secured at one end to the frame-plate and at their other ends to the arms 47, Figs. 2 and ll, the ratchet-wheel engages the pawl 5U, thus rotating the tripping-shaft 45, so that the next pin 4U is brought in position under one of the pawls The projection 55 of the retaining-pawl 54 engages with and is operated by a cam 59-in the cam-bar 22, Fig. 7. The effect of this is that as the reset-levers 24 are deprcssed,d rawing the cam-bars 2:? forward, the arm 5o, by means of the cam 59, is raised, thus releasing pawl 54, the projecting end of which also releases pawl 5C. The tripping-shaft 45 thus being free the spring 52 rotates the same until the stop-arm GO strikes against the crossplate 3, in which position the tripping-pin 49 is opposite the projection 44 of the pawl 5 corresponding to the right-hand or units rackbar.

The Zero-key is loosely mounted on the shaft G7 and at its rear end is connected, by means of the links Gl, to a lever G2, Fig. ll. This lever carries the pawl G3, which is adapted to IOC IIC

IZO

engage with and rotate the ratchet-wheel 64, thus rotating the tripping-shaft one point each time the Zero-key is depressed. It will b e noted that the depression of the Zero-key does not lift the tripping-shaft 45, but does rotate it one point, The result of this is that it sets the tripping-shaft to position for operating the next higher order without operatin g any of the pawls to release the bars a.

Secured to the cam- bars 21 and 22 and extending across the machine below the rackbars 1 is the reset-bar 65, Figs. 2, 7, and 8. As the bar 21 and 22 are drawn back this reset-bar 65 engages projections 66 on the bars 7. rlhe result is that the bars 7 are first moved back relatively to the bars 4 until pawls 10 engage pins 11, the further motion of bar 05 moving the bars 4 into their initial position.

Having thus described the construction of the machine, I will proceed to describe the operation of addition by means of the same.

Let us assume that the machine is in its initial position, in which the Os show on the wheels 16 below the bar 29. Let us now add The operation is lirst to depress the hey Q. The result of this is that the transverse bar 31, which is the farthest back in the machine, is moved by the key-lever 9 longitudinally a sufficient distance t0 intercept any ac tuating-bar 1 that may move forward. Further depression of the key 9 raises the tripping-shaft 45, so that the tripping-pin 46 releases pawl 5 of the units-column. The spring 6 then rapidly draws the unit-bar el until the lip 83 strikes the bar 6 The result is that E) shows on the indicator-wheel 4.1, and the summation or addition wheel 16 is also moved from O to 9. As the key 9 is released the pawl 5 holds the bare in its newposition, and as the tripping-shaft is retracted by means of springs 58 the pawl 56 engages with ratchet 553 to move the tripping-shaft one point forward, so that the next tripping-pin fill will. be under the tens-pawl 5. Depressing the key we now move the stop-barl, operated by that key, so as to arrest the tens actuator or bar after moving forward the distance of eight rack-teeth, or four units. Then the tripping-pin a6 trips the pawl 5, which releases the tens-bar. The spring 6 moves the tens-bar forward four points, indicating L1- on the tens-indicator wheel 41 and on the tenssummation wheel 16. As the key iis released the stop-bar 31 resumes its normal position through means of springs 37. The pawl 5 holds the tens-bar -iin its new position. The pawl 56 again engages the ratchet 53 and moves the tripping-shaft one point, so that the pin 46 will be under the pawl 5, corresponding to the himdreds-column. New depressing key 2, stop-bar S1, corresponding to this position, is set, pawl 5, holding the hund reds-bar, is operated to release the hu ndredsbar, which moves forward two points, indicating 2 on the hundreds-indicator wheel ill and en hu ndreds-summ ation wheel 1 6. The

operator nonT has added 249, and it is necessary to bring the machine back to its initial position, which is done by depressing the bail 26, which, through reset-levers 24: and links 23, moves the cam-bars 21 22 forward, so as first to lift the shaft 1a and its pinions 16 out of mesh with rack-teeth 8 and hold these pinions in the rack-fingers 28. Furtherniotion of these reset-levers 24: operates, through the cam 59, the projection of the pawl 51,

which releases the ratchet-wheel 53, and thus allows the spring 52 to rotate the trippingshaft until held in its initial posit-ion by the stop-arm and against the plate 3. Further motion of the reset-levers brings the rset-bar against the stops 66 of all such bars as have moved rearward, and draws these bars back into their initial posit-ion, where they are held by pawls 5. Drawing these bars back in this way rotates the pinions 39, so as to show Os on the indicator-wheels 41, or, in other words, to show that the bars have all been properly reset. Releasing the bail 26 the springs 27 retract the reset-levers 2i, in which position the machine is again in its normal condition, the pinions 15 again meshing with the rackteeth 8.

If now we add tothe machine 101, we first strike key 1, which sets the stop-bar 61, disen gages the units-pawl 5, and allows the unitsbarl to move rearward one' point. In so doing the units-wheel 16 passes from the position of 9 to 0, and the tripping-pin 17, While the wheel is passing from 9 to O, comes in contact with the projecting lip 13 of the pawl 10, secured to the tens-bar. This releases the holding-pin 11, and the spring 0 of the tens-bar nieves the rack-bar 7 rearward one point, thus moving the tens-wheel from 4c to 5, or, in other words, this operation carries 1 from the units to the tens bar. Now depressing key O we rotate the tripping-shaft again from the tens position to the hundreds position without, however, releasing the tens-bar. Touching the key 1 we set the corresponding stop-bar 31 and release the hundreds-bar, which thus adds 1 7 to the 2 already added onthe hundreds- Wheel. The summation wheels thus show 350, or the sum of 249 and 101. Depressing the bail 26 the indicator-wheels are again set to O and the tripping-shaft brought to its initial position, when we are in position to proceed with the addition of the next number.

For purpose of convenience the complements of the numbers shown through the a depending arm 70, which is connected by IOO IZO

link 7l with the given actuating-bar l. The face of the type-segment is provided with a series ol numbers from l to O, as shown in Fig. ll. In place of O I provide a dot, as shown. As any bar l moves forward through link 7l and arm 7 O it rotates the typesegmentin proportion to the rearward motion of the bari or the amount added. Levers 73 are secured by pivots 72 to the side frame. These levers have two arms, one extending upward and carrying the shaft 74C, on which is mounted the impression-roller 75, the other or substantially horizontal arm being provided at its forward end with a cam-roller 7 G, which is adapted to engage with and be operated by a projection 77, secured tothe cambars 2l and It will be noted that as the bar 22 is drawn forward the forward end ofthe horizontal arm of lever 73 is raised by means ot the projection 77, thus bringing the impression-roller 75 against the type-segments. Mounted in the side frames are the feed-rollers 7S, 70, and SO. The feed-roller SO is provided with a ratchet-wheel Sl, which is adapted to be engaged with and operated-by the pawl S2,which is mounted on the upper arm of lever' 73. As the end of lever 73 through cam-roller 7G is oscillated this pawl S2 engages the ratchet Sl, and thus moves the feed-roller. Mounted on a shaft S3 is a suitable spool bearing a strip of paper which passes around the impressionroller 75 and between the feed-rollers 7S, 79, and 80.

The operation of this printing attachment is as follows: Touching the keys in succession from the units, tens, die., the different actuating-bars et move forward according to the amount added. These bars, through the links 7l, thus bring opposite the impression-roller 75 the figures on the segment G9 corresponding to the amount added. Then the bail 2G is drawn down to reset the machine, the iirst motion of this bail, through cam 77, presses the im pression-roller 7 5 against the type,thus making an impression on the paper strip. On the retraction of the reset-levers the cam 7 7 again operates the impression-roller, and if the machine has been properly reseta line of dots is printed, thus showing that themachine has been properlyT reset, the paper at cach operation being suitably moved forward by means of the pawl.

In Fig. l5 l have indicated the general appearance of a strip on which the amounts added have been recorded. The advantage of printing a series of dots is to show any improper resetting of the machine. A record of the amounts added and of any failure to properly reset the machine is thus secured.
