Specification of Letters Patent. Patented Jam. 25, llg ll lll.

Application filed February 23, 1909. 'S erialNo. 479,410.

Be it known that l, HUBEn'r, HOPKINS, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new. and useful Improvement in Copy-Holders, of 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 same, reference being had to the accompanying'drawin'gs, forming part of this specification, in which- Figure l is a perspective view of my improved copy holder. Fig. 2 is a; side ele-.-

. vational view of the lower part of the holder.

Fig. 3 is a sectional view on line 33, Fig. 1. F 1g. d s a view illustrating the details of certain parts of the device. Fig. 5 15 a rear BlGViltlOIltll VlQW of the part shown in Fig. 3. v

This lnventlon relates to. a new and usetul improvement in copy holders suchias are used by' stenographers and others in t-ranscribing notes or copg, the object being to e y when the guide or provide means wher indicating bar is operated step by step to indicate the different lines it will be moved I the proper distance between lines.

Great trouble has been experienced heretofore in the bar being moved too far as the operator strikes the guide or lever to effect. the lin'e spacing of the bar.

My invention, therefore, consists principally or means for preventing the overthrow of said bar and, 1ncidentally,. in the construction, arrangement and combination of the several parts, all as will hereinafter be described and claimed.

In the drawings, 1 indicates a supporting frame, on which thesheet or book to be copied is arranged, said sheet or book being held in position'by shelf-like projections 2 and clamping fingers 3. These clamping fingers are shdingly mounted in ways and connected to rock arms t on a shaft 5, which shaft has a lever or handle 6 for operating it. A spring 7 holds the fingers retracted.

8 is a guiding rod mounted on the side of frame 1, on which is mounted indicating bar 9. 10 is a cable connected to said bar and passing over a sheave 11 at the upper end of support 1 anda sheave 12 at the lower end of said support. Sheave 12 is loosely mounted on a sleeve 13 in turn loosel mountecil on a shaft 14. Shaft 1 1 exten s transversely across the support '1 'be locked in its adjusted position.

When the inner raised edge of the dog 19 and is provided with operating'handles or levers 15 at each end, which handles are preferably pinned to the shaft. One of the handles 15, the one fixed to the end of the shaft, adjacent to the sleeve 13, is provided with rearwardly extending finger 11) which is normally supported upon a post 17 extending from the support 1. Finger 16 co operates with a lateral projection 18 on the end of a feed pawl or; dog 19 pivotally are normally held in their lowered position against the post 17 in which position the post enters a recess in the lower edge of arm 20 (see Fig. 4),. and lifts the inner end of the dog 19 so that its teeth are held out of engagement withthe milled edge of the, disk 22. Whenever either handle 15 is depressed, the finger 16 by engaging the lateral projection 18 forces theftoothed end of dog 19 into engagement with the disk, the continued ,upward movement of finger 16 rotating the disk.

In orderto limit the forward movement of finger 16, and at the same time prevent overthrow of the disk, I project the upper inner edge of dog 19 above the arm 20 and arrange an adjustable post 25 in its path of movement. This post extends through a curved slotin the flange of the support 1 .and'is mounted on an arm 21$,having an axis or movement about the sleeve 13, on

of the post is provided with a milled head 27' and its inner endis threaded to receive. a screw extending from the arm 26. When the post 25 is screwed down it clamps the edges of the curved slot so that the post may contacts with the post 25 it jams the teeth of thedog against the disk 22, bringing the parts to a position of rest to prevent overthrow of the disk. The rotary movement of disk 22 may be adjusted by positioning the post 25. I prefer to have the milled ed e of dog 19 and the disk 22 in the form 0 fine teeth so that fine adjustment in the stroke .whereby the arm 20 and its carried dog 19 which it is loosely mounted. The outerend struction, arrangement and combination of the several parts of my devicecanbe made and substituted for those herein shown and described, without in the least departingfrom the nature and principle of my invention.

' Having thus described my invention, what Iclaim is r- I 1. In acopy. holder, a support, a guide bar, a cable connected to said guide bar, a sheave on which said cable passes, a shaft on which the sheave is loosely mounted a ratchet conjoined to said sheave a spring held arm movable about the axis of said ratchet, a pawl carried by said arm, adjustable means cooperating with said pawl to jam it against the ratchet thereby preventing overthrow of said ratchet, and a lever fixed on each end of the shaft for operating thesame and the ratchet and pawl mechamsm.

2. In a copy holder, a support, a guide bar, apawl andratchet mechanism for effecting a step-by-step movement of said -guide bar, means for actuating the pawl,

means on the support for-normally holding the pawl dis-engaged from the ratchet, and adjustable means for jamming the point of the pawl against the ratchet at the end of the stroke of the pawl actuating means whereby overthrow of the ratchet is prevented.

3. In. a copy holder, a support, a guide bar, a cable connected to said guide bar, a

sheave around which said cablepasses, a

ratchet conjoined to said'sheave, an arm movable about the axis of the ratchet a gravitypawl on said arm, means for holding when op oavgeie the point of the pawl disengaged from the {the shaft, oneof which levers engages the pawl andmoves the point thereof into engagement with the ratchet when the shaft is rocked 5. In a copy holder, a support, a rock shaft journaled therein, a sheave loosely mounted on the rock shaft, a cable operating on said sheave, a guide bar carried by the cable, an arm loosely mounted on the rock shaft, a gravity pawl carried by said arm, a lever fixed on the shaft'for imparting movement thereto, which lever engages a part of the pawl, and stops on the support in the path of travel of the pawl.

6. In a copy holder, a support, a. rock shaft jour naled therein, a sheave loosely mounted on the rock shaft, a cableoperafl ing on said sheave, a guide bar carried by the cable, a ratchet an arm loosely mounted on the rock shaft, a gravity pawl carried by said arm, a lever fixed on the shaft for imparting movement thereto, which lever engages a part of the pawl, a fixed stop on the support for normally holding the point of the pawl away from the ratchet, and an adjustable stop in the path of travel of said pawl for jamming the point of the same against the ratchet at the end of the stroke of the pawl-carrying arm. a

In testimony whereof I hereunto afiix my signature in the presence of two'wltness'es,

this 18th day of February, 1909.
