Specification of Letters Patent.
EiPateint-ted Bec. 27,
Application filed October 17', 1908. Serial lto\.'lii,26,
To all whom it may concern:
Be it known that I, Hummm' llorKINs, a citizen ot' the United States, residing;I at Sti. Louis, Missouri, have invented 'a certain new and useful lImprovement in Copy-Holders, ot' which the following' is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the saine, reference beingl had to the accompanying drawings, forming' part of this specification, in which- Figure 1 is a perspective view ot' a copyholder constructed in accordance with my invention; Fig. 2 is an elevational view of the right-hand side of the holder; Fig. 23 is an elevational view of a portion ot' the letthand side ot' the holder; Fig'. y-lis a rear elevational View ot' a portion oi the holder; and Fig. 5 is a detail. vertical sectional View of the upper portion ot' the support illusv4 trating the construction of the clamping device.
This invention relates to copy holders suoli as are generally yused by stenographers for holding a sheet of paper or bool; in an approximately upright position while the contents of same is being transcribed on a typewriting machine.'
One object 'ot' my invention is to provide a copy-holder that con'iprises a guide, and means under control of the operator for spacing said guide or moving it. downwardly' step hy step so that the operator-s eye `Wlll accurately follow the lines of printing' or Writing on the sheet or page that is being copied.
Another object isto provide a copy-holder having a support and a guide extending' transversely over the support and constructed in such a manner that it adjusts itself automatically to the thickness ot' the book or other object that` is arranged between the guide and support.
Another object isto provide a copy-holder having a guide, mechanism under control oi the operator for moving said lguide over the support, and means whereby the operator can manually move the guide without first disconnecting or changing' the position ot the guide-moving mechanism.
Another object is to provide' a copy-holder having' aclamping device and means located at one side of the support on which the sheet or book Jfor operating' said vention is to provide a side flanges 2 and adapted to is neat and compact.
l tfzlampil'lg" iid still another vobject ot my in *i copy-holder that is compact and which prdttents a neat and orn namental appearance. l
Referring' to the drawings which trate the preferred forni ot iny invenion. l`
holder on lwhich a sheet or hoolt is adapted to rest, said supptn'ting` surface preferably consistingr ot' a sheet ol metal that has its edge portions hcnt reaiwrardl;Y to jnfo'duce side flanges 2 and a top tlann'e ll. 'ihe support l is retained in an inclined position. as shown in Figs. 1 and 2, hy means ot a U- shaped member 4 pivotally connected to the locked by means ot hooks 5 pirotally connected the side flanges 2 and cooperating' with a har 6 carried by said tit-shaped member. il/"hen the holder is not in use the tlshaped nien;- ber 4t and hooks 55 are folded inside of the side tanges 2, thus producing'a device that 1t will he obvious, however. that any suitable means could be. employed tor retaining' the support in an upright position Without departing from the spirit of my invention.
The support l is provided adjacent its lower-cud with stops 7 on which the lower edge ot' the sheet or book can rest and in the preferred form of my invention, as herein shown` said stops consist or" portions of the support l that are cut and bent outwardly. At the upper end of the supjjiort is a clamping' device S that projects over the sheet or loool; which rests on the support, said clamping' device heilig' provided with a shank 9 'that passes through a slot in the support and pivotally connected to an arm l0 on Aa transversely extending' shaft ll. tu arm 1Q that is securely fastened to the shaft 11 is connected to one end ot a coiled spring 13 which has its opposite end connected to a stud 1ston the inside tace ot one ot the sidel flanges 2. as shown in Fig'. and on the outer end oi said shattis an operating handle or lerer lthat is located at the lefthand side oi the support l, as shown in Fig. l. rlhe lever i5 is adapted to he depressed to move the clampi1ig de\'ice ad away trom the support and the springs'` Al' `operates to draw said clamping' device toward the support' to securely`clamp the sheet or hoot: resting' upon the support.

support, and movement is imparted to said U-shaped device by means of a belt 2O that passes over pulleys 21 and'22, and has its opposite ends connected to a I'1J-shaped device 17a slidingly mounted on the rod 18 and arranged between the legs of the device 17 that carries theguide 16. The belt 20 is preferably connected to the Ushaped device 17n in such a manner that said device can move directly, over the pulley 21 and thus carry the guide 16 up close to the upper end of the support 1, this being accomplished by connecting the end 202 of the belt that leads from the pulley 21 to the lower leg of the leads from the pulley 22 to the upper leg of the device 17, as shown clearly in Fig. 2. l The pulley 21 is carried by a stud 23 that is adjustably mounted in an elongated slot 24 in the right-hand side flange, as shown in Fig. 2, so as to enable said pulley to be moved away tlrom the pulley to keep the belt 20 taut. The pulley 22 is loosely mounted on a horizontal rock shaft 25 that extends transversely through the side anges 2. Levers 26 are secured to the shaft 25 at each side of the support 1 and the lever at the ri lithand side of the support has an extension 26a to which a pawl 27 is pivotally connected. This pawl 27 has line serrations or teeth that are adapted to engage a tine toothed 'ratchet wheel 28 secured to the pulley 22 and thus impart movement to said pulley and to the belt 20 whenever either of the levers 26 is depressed, the movement 'of the belt 2O of course causing the guide 16 to move downwardly over the support 1. The levers 26 and shaft 25 are returned to normal position by means of a coiled spring 29 having its upper endconnected to a pin 30 on the inside face of the liange 2 at the lefthand side of the support and its lower end connected to an arm 31 that is secured to the rock shaft 25, as shown in Figs. 3 and 4. The pawl 27 is drawn toward the ratchet wheel 28 by means of a springr 32 connected to the righthand lever 26 and aving a hook that engages a pin on the pawl 27. lvlhen the roclrshat't 25 returns to normal position. shown in Fig. 2, the pawl 27 is autonically disengaged from the racliet wheel by means or" a rigid stop or pin iwith which said pavvl comes inv contact, said pin Si?. projecting laterally from the flange 2 at the righthand side ot the support and coon the flange 2 at the righthand side of thedevice 17a and the end 20b of the belt that evaero operating with the extension 26a on the righthand lever 26 to limit ,the movement ot the rock shaft 25 in one direction. The movement of said rock shaft in the opposite direction is limited by a stopg that is adapted to be engaged by an extension 26b support whenever either of the .levers 26 is depressed. This stop 3e controls the stroke of the pawl 27 and thus constitutes the means for governing the feed or degree of movement imparted to the guide 16 and, in order that said guide may be moved downwardly for different distances, l'. have made the stop 34 adjustable.
ln the preferred form of in yinvention as herein shown, the stop 34 consists of a clamp nut mounted on a screw-threaded device that projects laterally from a.r lever through an elongated slot 36 in the flange 2 at the lefthand side of the support, the lever 35 being looselym'ounted onthe rock shaft 25. The operator can setthe stop 34 in such a position that the spacing or step bystep movement imparted to the guide 113' will correspond to the spacing of' the lines being copied and, as the pawl 27 is automatically disengaged from the ratchet Wheel 28 when the levers 26 return to their normal elevated position, the o erator can manuall move the guide upward y or downwardly without first disconnecting the guide-moving mechanism or changing the position of same. The guide 16 is carried by the U-shaped device 17 that slides on the rod 18 but said guide 'iS not rigidly connected to said device. The
device 17 is providedwith a pair of kupwardly projecting studs 37 one of which has a head, as shown in Fig. 1, and the inner end of the guide is provided with holes through which said studs v ass so that the guide can/ move vertica ly relatively to the device 17v and supportl and thus automatically adjust itself to the thickness of the bool( or object interposed between tie guide 'on the lever 26 at the lefthand side of the and support. By mounting the guide in,
this manner I insure that the guide will always lie parallel to the support and never' at an angle thereto as would occur sometimes if the inner end of the guide was rigidly connected to the device 17 whichcarries it, The guide can be swung upwardly, away from the support when the sheet or book is being arranged in operative position, and when said guide is swung back to its operative position it will lie perfectly flat on the'sheet or book. j
A copy-holder of the construction above described is compact and presents a neat and ornamental appearance and is superior in a number of ways to the copy-holders which have heretofore been in use.r 1
