EXTENSIBLE COPY-HOLDER AND GUIDE.

Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed April 26, 1911. Serial No. 623,462.

To aZZ whom it may concern:

Be it known that I, JOHN I. Woonsrnoivr, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Extensible Copy-Holders and Guides; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

Copy holders as used by stenographers and others are frequently constructed so cheaply as to lack the necessary strength to properly support the book or other article from which the copy is to be taken, and in most instances, are not capable of such extension as to permit of any but small sheets being supported thereon. Furthermore, as such holders have heretofore been constructed, there has been no satisfactory means for directing the eye of the typist to the work, and in consequence, many errors are occasioned through repetitions and through the omission of a word or words, rendering the copy valueless and necessitating the work being done over.

It is an object of this invention to afford a copy holder adapted to be extended laterally to afford a substantial support for the material to be copied, whether of wide or of narrow size, and also to afford a guide whereby the attention of the copyist is at all times directed back to the line from which the copy is taken, thereby avoiding duplications and omissions.

It is also an object of the invention to afford a construction whereby the operator adjusts the sight guide by means of a key or lever, so that as each line is copied a succeeding line or lines may be brought into view of the operator.

It is also an object of the invention to afford ready adjustability of all parts and to afford an exceedingly strong, simple and durable device of the class described, the mechanism of which is so constructed as not readily to get out of order.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

Fig. 2 is a side elevation thereof. Fig. 3 is an enlarged section on line 83 of Fig. 2. Fig. 4: is an enlarged section on line 4-l of Fig. 1. Fig. 5 is an enlarged section on line 5-5 of Fig. 1. Fig. (3 is an enlarged. l

section on line (3-6 of Fig. 1. Fig. 7 is an enlarged section on line 77 of Fig. 1. Fig. 8 is a fragmentary section on line 8-8 of Fig. d. Fig. 9 is a fragmentary section on line 9-9 of Fig. 2. Fig. 10 is a fragmentary section on line 1010 of Fig. 4. Fig. 11 is a fragmentary section on 1lll of Fig. 3.

As shown in the drawings: 1, indicates an upright or standard of anydesired height and cylindric in form, and rigidly secured upon a weighted base or foot piece 2. An inclined frame plate 3, is provided on the side thereof with a clamping eye 4, to receive said post or standard 1, therethrough, as shown in Figs. 1 and 2, and a set screw 5, is provided on said clamping eye to rigidly engage said frame plate in the desired adjusted position. Journaled on the top of said frame plate is a wheel or belt pulley 6, and journaled at the lower end thereof is a corresponding belt pulley 7, trained about which and the pulley 6, is a belt 8. pulley 7, as shown, is rigidly secured on its shaft 9, which is rotative in the frame plate and rotatably secured also on said shaft at one end is a lever or arm 10. which extends outwardly alongside the pulley wheel 7. and is provided with a spring pressed pawl 11, thereon which engages a grooved friction wheel 7 to drive the same. Said lever, as shown, is provided on its outer end with a finger piece 12, and, as shown, an arm 13, is provided on the frame plate 3. and engaged thereon is one end of a coiled spring 14, the other end of which engages beneath the lever 10, as shown in Figs. 3 and 11, and acts to elevate the same. An arm 15, extends beneath said lever 10, and is provided with a set screw 16. to limit the amplitude of movement of said lever to determine the adjustment of the sight guide bar on the machine. Secured at one end on said frame plate are parallel upper and lower guide bars 16 and 17. These. as shown, are tubular and are rigidlv engaged in the frame plate 3, at one end by riveting or anv suitable means. Birridly connect ng said frame bars 16 andl'? together, adiacent to the ends thereof, are metallic supporting Said plates 19, which, as shown, are bent to engage about the upper frame bar 16, and about the lower frame bar 17, said supporting plates, however, at said lower bar being bent outwardly at a right angle with the face thereof to afford a shoulder or ledge 19 on which the copy rests at its lower edge.

Clamping fingers 20, are pivot-ally secured on the frame plate and are adapted to swing inwardly to engage the copy against the supporting plate 19, adjacent the frame bar. For this purpose, as shown, straps or eyes 21, are provided on the rear side of the frame bar near each end thereof and a metallic rod is bent to afford the engaging or clamping fingers 9.0, as shown in Figs. 1 and l, and, as shown, a finger piece 22, integral with said rod is provided near the middle thereof and serves as a lever to tip said clamping fingers upwardly and outwardly to release the copy or to swing the same inwardly into engagement therewith, and a strong spring 23, is provided on said rod near one end thereof and bears against one of said fingers and against the frame plate at the respective ends thereof and acts to hold the clamping fingers outwardly in position to engage the copy.

Slidably engaged in the tubular frame bars 16 and 17, is an extension frame comprising a piece of wire or metal tubing bent to afford top and bottom rails and a side rail 24 and 25 respectively, the top and bottom rails 24, of which engage respectively in the tubular top and bottom rails 16 and 17. Said extension frame is adapted to be readilv drawn outward when required for use. when copving material from relativelv wide paper. Clamping means are also afforded for engag ng the paper book or other material to be copied, thereon. For this purpose. links 26, are rig dly secured on said extension side frame bar 25, and journaled in the extremity of the links is a rod or wire 27, each end 28, of which is bent upwardly from the bodv of the bar and curves inwardly to normally engage when the device is in its contracted form on the outer supporting plate 19, or that on the outer ends of the tubular frame bars. An integral lever 29, is provided on said rod to operate the same and a pulling spring 30, is secured on one of said fingers and engaged to the side frame rod 25, and acts to hold said fingers inwardly at all times, as shown in Fig. 6. in gripping position. Secured on said belt 8, and extending transversely the frame and in horizontal position, is the line guide bar 31. This, as shown, is constructed of relativelv light sheet metal turned to afford a guide slide and having slidably or extensibly engaged therein the extension guide finger 32. As shown in Figs. 1, 2, and 4*, an additional guide bar 31 is fastened to the belt 8 substantially opposite to the guide bar 31, so that said belt 8 may be rotated continuously in one direction, which will at all times bring one of said guide barsinto operative position at the front of the device. As shown, the belt may be tightened by adjusting the pulley 6, at the upper end of the frame-bar upwardly or downwardly in the slot therefor through said frame bar and through which the shaft 33, for said pulley extends and on the outer end of which is engaged a set nut 31 whereby said shaft may be rigidly clamped in adjusted position.

T he operation is as follows: The copy is placed upon the supporting bars 19, with the bottom thereof resting upon the ledge or shoulder 19, at the bottom thereof. The clamping fingers 20 and 28, are then brought into engagement therewith, as shown in Fi g. 6, firmly holding the samein place. The guide bar is then adjusted to the line it is first desired to copy. This may be done by manually operating the lever 10. the pawl on which engaging in the grooved friction wheel 7*, rotates the shaft 9. thereby rotating the belt wheel 7. and driving the belt. and, of course, moving the guide arm therewith until the same hasreached the required position at the top of the page to be copied. The throw of said lever is adjusted during this preliminary movement so that each full actuation thereof is sufiicient to adjust the guide bar a distance equal. to the space be tween successive lines of copy. This having been done, the operator may proceed with the transcription of the copv, and as each line is copied he actuates the key or lever 10, thereby dropping the guide bar space by space and in each instance exposing the line .or lines next to be copied. Should the material to be copied be upon wide paper or a side opening book, the extension frame may be used. For this purpose. it is only necessary to draw the extension frame outwardly, as shown in dotted lines in Fig. 1, a sufficient distance to suit the requirements of the particular sheet or book to be copied, whereupon the clamping fingers are engaged thereto as before described, firmly holding the same in adjusted position. The lever 29 affords a ready means to be grasped for extending or retracting said extension frame, and at the same time the rod 27 may be turned thereby to move the gripping fingers 28 to their open or releasing position. Of course, the guide bar 31, may be also extended by pulling the slide section 32, therefrom sufficiently to correspond with the length of the line to be copied. The operation is, of course, as before described. Inasmuch as the inner side of the clamping fingers or those secured to the frame bar are sufficient for ordinary widths of adjustment, the extension frame may be sold as a separate article of manufacture,

and may be readily inserted in position at any time by merely inserting the top and bottom guide bars 24, into the respective tubular bars 16 and 17. Should it be necessary to tighten the belt, this may be accomplished as before described, by shifting the upper belt pulley 6, upwardly, the slotted aperture for the shaft 33, therefor and the set screw 34, thereon permitting this adjustment.

Of course, details of the construction may be varied. I therefore do not purpose limiting the patent to be granted on this application otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the class described, a supporting frame, a laterally extensible frame slidably engaged therewith, gripping fingers on said supporting frame, a rod arranged longitudinally of and pivoted to the outer end of said extensible frame, gripping fin gers on the ends of said rod for engaging the copy, a handle on said rod intermediate said gripping fingers, a spring for normally re- 4 taining said fingers in gripping position, a horizontally disposed extensible line guide finger, and means for adjusting said line guide finger space by space as the copy progresses.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

JOHN I. WOODSTROM.
