Specification of Letters Patent.

Patented Jan. 16,1912.

Application filed January 6, 1908. Serial No. 409,550.

To all whom t may concern Be .it known that I, RUSSELL B. Gnirrrrn,

a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Copy- Holders; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

My present invention relates to copyholders for use in transcribing and to those of the'type providing for a stationary line indicator and movable copy and it has fficll an durable device of this nature whic indicate, successively, upon the copy for the guidance of the writer the lines to be transscribed in their proper order and which, when used in conjunction with a writing machine, may be conveniently placed with reference thereto and easily .pages that have been transcribed.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of this specification.

In the drawings: Figure 1 is a perspective view of a copyholder constructed in accordance with my invention and illustrating one embodiment thereof. Fig. 2 is a rear elevation of the same. Fig. 3 is a side elevation. Fig. 4 is a transverse or horizontal section on the line 4-4 of Fig. 2. Fig. 5 is a similar view on the line 55 of Fig. 2. Fig.6 is a rear detail view showing the clutch mechanism and adjacent parts in their relative positions when "the copy plate has reached its upward limit of move- 'ment. Fig. 7 is a vertical section through the shock absorbing element in detail and willoperatedthrough means readily. accessible from the Fig. 8 is a detail side elevation of the copy retaining mechanism after being operated from the position shown in Fig. 3.

Similar reference numerals throughout the several figures indicate the same parts.

Referring more particularly to the drawings, 1 indicates a supporting member, preferably in the form of a frame having a cross bar 2at its top and a base bar 3 at its bottom, one end of which latter is provided with a leg 4 while the other has a projecting portion 5 fitting into a mortisein a side bar 6 and secured as by the screw 7. The side bar extends transversely to the frame and preferably at right angles thereto, its

relative position being rigidly maintainedby a coextensive angular portion 8 on the base bar and a screw 9 in addition to the screw 7. By this construction the supporting frameis held in an upright and preferably vertical position rearward extensions 10 and 11 on'the leg 4 and side bar, respectively, and the forward end 12of the latter forming a solid three point bearing.

The copy plate 13 is preferably formed of thin sheet material and rectangular in outline, its dimensions approximating the maximum dimensions of the copy sheets which it is designed to accommodate "and on its rear side is fitted with a lifting rod 14 rigidly secured thereto as by the brackets 15 to form a part thereof and guided in the cross bar 2 of the supporting frame. The latter is also fitted with parallel, vertical guide rods 16 and 17 extending between the cross bar and base upon which are guided the brackets 18 and 19 on the copy plate so that the latter bears a fixed relation to the having at its forward end a finger piece or key27 and at its rear end a stud 28 bearing in the slot 23 in the actuating lever 21 transversely to which latter the operating lever extends. The said stud is provided with a headed portion 29 that is normally disposed transversely to the slot and prevents disengagement of the members but is nevertheless of substantially the same shape and canbe passed therethrough in assembling when the 2 side bar and its attachments are held in a 2 vertical position before the screws 7 and 9 are applied as will be understood. A detachable though interlocking and pivotal connection is thus established between the 'two levers, joining them for movement'in vate the clutch rod intermittently, its-- throw being regulated by an adjustable stop .in theform of a screw threaded into a forwardly extending arm 31 on the post 24.

- By this arrangement the stop can be brought close enough to the fulcrum 25 of the lever to be squarely engaged thereby and to materially affect the extent of movement of the latterby arelatively slight adjustment while readily accessible to the operators fi r gers from above the lever.

- Pivoted at 32 through. a yoke at its end to the upper end of the clutch rod 20, is a mov;

able clutch 33 comprising a bar having an aperture therein through which passes the lifting rod 14 on' the copy plate, the aperture being slightly larger than the lifting rod permitting the bar to bind thereon when tilted in a well known manner. It is normally held in binding engagement by a spring finger 34 but being. abovethe cross bar 2 is disengaged by contact of its free end with the latter when the clutch rod is lowered a suflicient distance. Below the bar is arranged a retaining clutch 35 (*Figs. 2 and 4) similar in character and shape and also engaging the lifting, rod 14 but pivoted on a pin 36 on a projection 37 of the supporting frame. Itis normally held in binding engagement with the rod by a spring or tension member38 interposed between it and the cross bar. but is released by the engagement of a projecting pin or abutment 39 on the clutch rod with its opposite yoked end 40. A spring 41 extending between the base bar 3 and actuating lever 21 normally tends to hold- ,t-he latter and the actuating rod in lowermost position, that is, with the movable clut ch adjacent to the cross bar and the tripping pin 39 against the retaining clutch but'is not suflicientlystrong to cause .the release of the latter by overcoming the tensions of the springs 34 and 38.

Pivoted at its ends 1n lugs 42 on the sup-.

I porting-frame is a yoke 43.carrying a line indicating plate 44 extending across the face of the copy plate, while at the topof the latter is arranged a copy holding clip 45- which clamps, the copy sheets against the face of the copy. plate behind the lineindicator. The yoke 43 is preferably composed of resilient material and held slightly sprung in its bearings so that there is maintained a slightly inward pressure at its ends sulficient to hold the line indicator inany' desired adjusted position, up or down or toward or from the face of the copy plate, within certain limits, as indicated in full and dotted lines in Fig. 3. I

The operation of the device as thus far described will now be briefly explained.

The copy-having been secured in place on the copy plate in the manner indicated, and assuming the latter to be in its lowermost. position on the guides and the clutch devices in their normal positions shown in.

Fig. 2, when the operating lever 26 is depressed, the actuating rod 21 is moved in the opposite direction and the clutch rod 20 raised a certain distance. The movable clutch 33 carried thereby grips the lifting rod 14 with the aid of the spring 34 and elevates the copy .plate 13 a correspond ng amount. When the operatinglever is released, the parts are returned to their former positions, -(the said clutch being movable relatively to the lifting rod in that direction) with the exception of the copy plate which is held in'its elevated position bythe action of the retaining clutch 35 aided by the spring 38. Successive similar operations of the lever duplicate these movements, each movement resulting in the line of the copy previously indicated by the line indicator 44 being raised above the latter to disclose the next and the throw of the lever is regulated i by means of the adjustablestop 30 to bring about this result. When the last line on the sheet has been copied, or at any previous point in the. travel of the copy plate, a reverse or upward movement of the operating lever lowers the actuating lever and trips both of the clutches in the manner previ-- ously described, whereupon the copy plate is allowed to fall or slide downward to its former position ,ready for the insertion of a new sheet. a r To prevent a continued operation of the lever, after the upward limit of movement straining or perhaps injuring the parts, I provide a projection here presented in the form of a shoulder or sleeve 46 at the base of the lifting rod which automatically en gages and trips the retaining clutch 35 at .of the copy plate'has been reached, from this point, as shown in Fig. 6, the'extreme movement of the lever being preferably suflicient to cause the said clutch to lock in the opposite direction. Should it lock, howsult is in either case. that the=copy plate will simply move up and down through a limited space andwarn the operator that the return movement should beeffected. Also, to prevent the copy plate from binding on its guides when thus elevated, I proever, the two clutches would only act again t each other upon the lifting rod. T e re;

vide a tension member between it and the support which is flexed by the last effective movement of the clutches andin the'present instance comprises a light spring 48 coiled about the guide rod 16 and carried by or on the bracket 18. It is compressed between the latter and the cross bar 2 and, when the clutches are released,'accelerates the return movement of the copy plate and causes its instant descent.

Arranged, in the present embodiment of the invention, at the base of the guide rod 16-is a cylinder 49 (shown in detail in Fig.

7) within which operates a piston 50 having a tubular stem 51 sliding on the guide rod, the latter extending concentrically of the cylinder and being secured in a bottom plate 52 held thereby against ashoulder 58 and provided with an opening 54. The cylinder may be conveniently formed in a single casting integral with the supporting frame and base bar 3 upon which it rests and the shoulder 53 counter-bored therein as well as an upper shoulder. 55 against which the piston abuts to normally limit its upward movement caused by the tension of a conical spring 56 encircling the guide rod and resting on the bottom plate. The piston itself may be packed in any suitable manner, as by a flexible diaphragm 57 secured between itsface and a plate 58, while sliding with it on the guide rod above its stem is a wear plate or washer 59 for the material of which commercial fiber will be found suitable. The object of the construction just described is to form a cushion for absorbing the shock of the descending copy plate when it is brought to rest. The bracket 18 is provided with a downwardly extending barrel portion 60 through which the rod 16 extends and which is adapted to enter the cylinder to operate the piston a full stroke, though it also contributes the.

function, by providing a long bearing on the rod, of steadying the copy plate when in the elevated position shown in Fig. 6, at which point the latters several guiding connections are, for the moment, very close together.

When the copy plate is released from an elevated position it falls rapidly until this barrel portion on the bracket engages the wear plate 59, from which point it is brought to a gradual stop by reason of an instanta-.

neous compression of the air within the cylinder andits gradual escape through the opening 54 at the bottom and also through v the compression of the spring 56. By forming the latter in a conical spiral it is ren-. dered compressible. into small compassand in no way interferes with a full stroke of the piston. .The copy plate being again elevated, the spring returns the piston to its former elevated position. It will be observed that while the ultimate. check given to the fall of the copy plate is thus made gradual, the function of the cushioning device is completed within a comparatively short space of its travel, while through the greater portion of its descent-it is free and unobstructed except by the friction of the guides,so that its return movement is made with great rapidity. i

The form of clip which I prefer to employ for securing the copy in place against the face of the copy plate will form the subject matterofa separate application but'is illustrated in Figs. 1, 2, 3 and 8 herein to show the manner in which it may be usefully combined with a copyholder of the character above described.- It may be convenient-ly constructed from a single piece of material such as wire and comprises in the present instance a yoke'having a bar portion 45 disposed across the face of the copy plate and having a looped portion 61 at one and preferably both ends,'the material beyond. the loops extending at right angles to the bar and again looped at 62, and thence -inwardly at 63 parallel with the bar, the inwardly extending portions being pivoted in brackets 64 secured to the rear of the copy plate. Aspring or tension member 65 nornially operates to press'the bar 45 agaiiist the face-of the copy plate, while the looped portions 61 are bent outwardly angularly to the general plane of the clip as shown in brackets 64 tomove upon an axis parallel with that of the other, but is fitted with a tension member 67 which normally presses it against the face of the copy plate in an opposite direction. It also being provided with an angularly disposed loop 68, it will be seen that both clips may be released and moved toward one another by pressing'the loops together. In this Way, the copy may be quickly removed from the holder and the action of both clips, or both may beraised and an open copy book inserted in such manner that they will simultaneously engage, one with the page to be copied and the other with those turned back. In either instance, the strain upon the'copy plate is slight, as the two clips Work against each other. As each page is copied, itis turned back on the bar 45 and slipped beneath "the leaf retaining clip by liftingthe latter through outward pressure on the finger piece. To obtain a greater range of'movev ment for both clips, and to make it conformmoreclearly to the naturally assumed position of the folded leaves, I prefer to bend or incline the upper end of the copy plate. 'rearwardly, as shown at 69. The brackets 64 are preferably disposed across the line of demarcation and. their fastening 71 areflicient in operation, while free from suchcomplexities of structure as would prohibit its production and sale at a reasonable price and its successful operation by persons possessed of but ordinary mechanical knowledge. While its usef lness is not confined to such an association, the machine is par: ticularly adapted to be arrangedin rear of a writing machine, in which position the copy is in the most natural position for observation by the typist and the operating key readily accessible from the keyboard of the machine.
