COPY HOLDER Jesse A. Holton, Sr., West Hartford, Conn., as-v signor to Underwood Corporation, a corporation of Delaware Application December 22, 1944, Serial No. 569,319-

Claims. (01. 120-42) This invention relates to copyholders and with regard to certain more specific features thereof to copyholders of the small or portable type adapted, in spite of their light weight and narrow width, to the accommodation of relatively wide sheets due to the fact that the width of the copy sheet associated with the holder is not limited by the width of the holder. Such copy' holders employ as a basic principle a structure such as is shown in the U. S. patentto Caldwell, No. 216,654.

It it an object of the present invention to provide a relatively small and easily movable copyholder for the accommodation of long sheets or webs so that the copyholder is adapted not only for use with ordinary correspondence or legal size papers but to stenographic copying or public address reading from inscriptions made on very long sheets or rolls.

. It is another object of the invention to provide reliably operative and inexpensive means for advancing such sheets from a container section of the copyholder to a receiver section where, after the completion of the copy, the sheet may be conveniently removed from the receiver section by widthwise withdrawal.

It is a further object to provide feed means which may be either operated locally at the copyholder, or by remote control from a machine on which the copy is being made, by incremental movements corresponding to the distance between the lines of write on the copy sheet, and to provide reliably operative and easily settable means for varying the length of the incremental movement either under control of the locally situated mechanical operating devices or the remote-controlled electromagnetic means for operating the feed means.

It is a still further object of the invention to provide a feed means employing coacting rollers arranged to engage the leading edge of the copy sheet for effectively gripping the sheet to ad-" vance it to the receiving unit.

Another object of the invention is to mini-- mize manufacturing cost by constructing the container unit and the receiving unit of uniformshape, and striking from each unit a uniform section which serves in the case of the receiver unit as a mounting for feed rollers and serves in the case of the container unit as a mounting for a line-finder device.

Other objects will be in part obvious and in part pointed out particularly as this description proceeds.

"The invention accordingly consists in the vari' ous features of construction, combination of elements, and arrangements ofparts, which will be exemplified by the. following description and the accompanying drawings, and the scope of the application of which will be indicated in the appended claims.

Referring now more particularly to the drawings:

. Figure l is a perspective view of the copyholder.

Figure 3 is a perspective view-. of certain dc-1 tails of the mechanism relating tothe varying of the incremental feed; and, the means for ad-. justing the mechanism to obtain the variation. Referring now more particularly to the drawings, there is shown a stamped metal casing. i0;

comprising a base member II and two upstand ing side walls l2. g-A removable plate l3 extends between and is attached to the side walls at the rear of the copyholder.

Mounted upon the base plate H, of the casing is anupstanding bracket I4 which may extend partially across the inside of the casing between the side walls. Secured to a vertical portion of the bracket M as by means of screw I5 is a volute open-ended sheet metal container member [6 corresponding in size, shape and general construction to a volute open-ended retainer member I! which is secured to a rearwardly extending portion of bracket by means of screw [8.

The container member l6 has a portion struck from it to form a supportingarm l9 and the receiving member ll has a similar struck-up portiOljiZfl.

The bracket M has an oblique portion 2| from which two spaced journal arms project, one of.

these arms being shown at 22 and the other is spaced an equal distance fromthe center line of each covered with a band of friction material 21 such as soft rubber, felt or other suitable material.

Centrally on the shaftv 24 there is fixed a ratchet, wheel 28 which has oppositely disposed hubs 29 secured to the shaft by set screws 30.

On the undersideoftheprojection 20 struck- ,out from the vreceiver member. ii is a. eaf sprin The copy sheet is indicated in Figure 2 of the drawings at 34 by the dot-and-dash line. In the event that it is a long roll, it may be introduced laterally by separating the leading portion of the roll slightly to pass edgewise into the channel 35 while the body of the roll is passed into the body 36 of the container member. Ordinary correspondence or legal sheets may be entered into the volute container memberby' passing the bottom portion of the copy sheet down. through the mouth 31. A straight downwardv movement will enter the. sheet through the channel 35. and around to the required extent in the body 36.. v

The struck-out arm is of the container member has mounted thereon a laterally extending bar '38 upon whichare mounted two. slidable extension members 39 which serve as a line finder and are conveniently extensible on the bar 38 and frictionally held. thereon to provide any reasonable length of line finder desired.

It having been described how the copy sheet may be entered as'shown in Figure 2 ready for feeding, the mechanism for operating the feed means incrementally and for-varying the incremerits offeed will now be'described. Suitable webs 40 provided on the bracket I4 journal a shaft 4| to which securedan operating lever. 42 having a finger-piece operating-end 4'3 and a rearward extension 44. Also secured to the shaft. 4lis an arm 45 connected at its outer end to a pawl 46 having a nose normally held in engagement with a tooth of ratchet wheel 28 by a spring 48 connected to a lug on the bracket [-4. A detent 50 mounted on the oblique portion 2lof bracket I4 also engages teeth of ratchetwheel 28 for the purposes of correctly positioning the ratchet wheel at the end of an increment or movement and preventing overthrow. Arm 45' and pawl 46 are normally held rearward by a spring 51 secured to the foot-of: bracket l4 and an adjusting screw 52 determines the normal or rearward position of the arm and pawlby engagement with a lug-53 on arm 45.- The adjusting screw 52 is mounted in -abracket 54 adjustable laterally on the bracket I4" by slot-andshoulder-screw' connectionsindicated in Figure 3 at 55. A spring detent member 56 arranged in bracket 54= engages with the edge of one side wall- 12 of the casing where it is recessed at 51, anda finger-piece 58 is provided projecting slightly "outsideof the casing for manipulation of the bracket into any of the positions 1, 2 and 3 indicated by these numbers. 1 Alug 59 is turned inwardly onthe" bracket 54 and 'is provided with stepped shoulders which 'a're selectively brought into line with the'movem'ent of-arm 45-by' 'm'anip-- ulation of the finger-piece 58 This provides 'for stopping'the pivotal movement of arm 45 atvary in g' points calculated to allow variable movement of'pawl 46 toproduce rotative-movementofieed roller 26 so that'it may be moved to feed the copy sheet in accordance with the typewritten linechine on which thecopying is being done.

- therefore, highly desirable to have a control for to its fullest extent will advance the pawl 46 to the particular shoulder stop Bil which is aligned with the arm 45, and thus full depression of lever 42 advances the copy sheet the required distance. Release of the finger-piece 43 allows spring 5| to return the arm and present the nose of pawl 35 to a new bite position in the ratchet 28.

The portable characteristic of this type of copyholder enables its ready movement to present the copy sheet in the most favorable light -and position to suit the operator and frequently this position is at some distance from the operators hands located at the keyboard of the ma- It is,

the operation of the feed of the copy sheet located on the typewriter or other machine where the copy is being made. To this end there is provided a solenoid operation for the lever 42 and its associated arm i5 and pawl 36.

The solenoid is shown at. .65 in Figure 2 suitably. mounted on the back. plate l3 and having finger-piece as, and mechanicaloperation of the. feed means, or by depression of the key of switch 64 remote from the copyholder, and electromag--.

netic operation of the feed means, may cause the copy sheet to be advanced. incrementally until it; is entirely rolled up in the receiver ll, from which.

it maybe quickly and conveniently withdrawn by a lateral movement as soon as its trailing edge:

has passed from. the bite or the feed rolls. For: withdrawing the. copy sheet during the copying.

process for the purpose of checking or other pur-:

pose, it isfonly necessary tolift the lip 33, reach behind the paper in the vicinity of roller 26 and: draw it forwardly, the trailing portion of the paper again taking its position in the channel 3.5- and the container member .16.
