. rllhis invention relates principally to copyholders of the type wherein the copy is held stationary in suoli position that it may be conveniently copied by means of a typewriter and the line that is being` copied is indicated by a movable marker that is moved with a stcp-by-step movement by the movement of the typewriter carriage. The. principal object of the present invention is to provide a simple and economical mechanism for actuating the marker of such device that is compact and easily operatedis not liable to ,fret

out of repair and may be readily adjusted to vary the extent of the step-by-step movement of the marker for different line spacing'. The invention consists in the copy-holder and in the construction, combinations and arrangements of parts hereinafter described and claimed.

I In the accompanying drawing-s, which forni part of this specification and wherein like symbols refer to like parts wherever they occur, f

Fig. 1 is a front elevation of a copy-holder embodying my invention,

Fig. 2 is an end elevation thereof,

3 is a front elevation of the copyholder. with the front wall removed,

Figa/4e is a vertical cross-section on `the line 2 4 of Fig. 1, with the sheet clamp in position to receive a sheet to be copied,

Fie: 5 is a vertical cross-section through the clutch pulley on the lower sprocket shaft, taken along the line 5 5 of Fig. 3, f

Fig. 6 isa fragmentary horizontal crosssection on the 'line 6-6 in Fig'. 1; and

Fig. 7 is a fragmentary vertical cross-section on the line 1 7 in Fig. 3.

A copy-holder in the form of a rectangular sheet metal box 1 provided with a removable cover 2 is vertically adj ustably supported on a stand comprising abase 3 provided with upright rods il. Said rods pass through openings provided therefor in the bottom of the box 1 and are slidably engaged-in vertical openings provided therefor in brackets-5 that are rigidly secured to the rear wall of said box adjacent to the lower end thereof. rThe brackets 5 are clamped to the respective rods 4- in any desired position of their sliding 1930. Serial No. 462,726.

that are to be copiedfroin are placed against thefront cover plate 2 ofthe box 1 and clamped thereagainst by means of a clamp comprising` a bail-shaped rod 7,.which exv tends from side to side of the box with its ends rotatablysupported in horizontal open- 60 ings provided therefor in lugs 8 that project outwardly from the upper corners of said box. A coil spring 9 is provided for swing'- ing the bail 7 towards the cover plate 2 of the box. The pages of the book that have been copied are turned back over the top of the box and are held in. such position by means of an arm or extension 10 which is formed integral with the bail 7 at one end thereof and extends parallel to the horizontally disposed copy holding' end thereof.

Located in the lower portion of the box 1 is a horizontal shaft 11 which extends from side wall to side wall of said box with its ends journaled in suitable bearings 12 there- 75; in. Located in the upper portion of the box 1 is a second horizontal shaft 13 which extends parallel to the lower shaft 11 with its ends disposed in vertically elongated slots 14 provided therefor in the side walls of 80 said box. The upper shaft 13 extends beyond one side of the box and has afknob 15 fixed thereto, whereby said shaft may be manually rotated. The upper shaft 1.3 is rotatably supported near its ends in bearing blocks 16 35 having pins 17 projecting vertically therefrom at the top and bottom thereof. The

4pins 17' of the block 16 slid-ably engage vertically alined openings provided therefor in the outstanding' flange portionsof brackets '90 18 that are rigidly secured to the rea-r wall of the box. Coil springs 19 are sleeved` on the lower pins of the bearingl blocks 16, between said blocks and the lower Vflanges of the` brackets 18, and thus serve to yieldably support the shaft 13 ournaled therein. Located in the box 1 adjacent to the sides thereof are endless sprocket chains 20, which pass over sprocket wheels 21 and 22 fixed to the parallel shafts 11 and 13, respectively, whereby 10E the the two shafts are adapted to rotate together. The coil springs 19, which support the bearings 16 for the upper shaft 13, serve to force said shaft upwardly and thus take up slack in the sprocket chains 20.

The front cover plate 2 of the boX 1 is provided opposite the sprocket chains 2O with vertically extending slots 23 adapted to accommodate fingers 24 mounted on said chains.' As shown in the drawings, each chain has two fingers 24 secured thereto, the two fingers being arranged so that when one finger is moving downwardly with one stretch of the chain the other linger is mov-5 ing upwardly on the other stretch of said chain. rl`he fingers 24 are pivotally supported on special links provided therefor in the sprocket chains E2() and have squared inner ends which abut against the chains during downward movement of the outer stretches thereof and thus maintain said fingers in a horizontal position. During the upward travel of the fingers Q() they are engaged bv the rear wall of the box and are swung downwardly into a vertical position alongside of the upwardlv moving' rear stretches of the chains. A guide bar or marker for indicating the line of the copy that is to be copied is sunported on the fin- 24 that project from the sprocket chains 20 through the elongated slots 23 in the front cover plate 2 of the box 1 and is provided at its lower edge adjacent to its ends with notches Q6 adapted to straddle said fingers and thus prevent endwise movement of said bar or marker.

The mechanism for turning the lower haft 11 to move the marker 25 downwardly a line at a time over the copy on the board is opeiated by an arm 27 pivotally supported adi acent to the lower righthand corner of the boX 1 for horizontal swinging movement transversely thereoft and the copy-holder is so positioned with reference to the type- 4.5"

writer that said operating lever is swung' to the right bv the typewriter carriage C when the latter is at or near the end of its return movement. As shown in the drawings, the operating arm 27. has its rear end pivotally supported in ears or lugs Q8 provided therefor `in the endof a channel-shaped bracket E2? that extends transversely of the box 1 and is rigidly secured to bottom thereof. The

,n operating' arm 27. which extends forwardly beyond the front face of the box 1, is pivotallv secured to the Aouter end of a yoke or link 30 located in the channel-shaped bracket 29. The opposite or inner end of the link 30 is provided with an opening adapted to slidably receive a pull-rod 32 which extends longitudinally of the channel bracket 29 under the channel thereof. The pull-rod extends into the opening in the link 30 and terminates at its outer end in a head 33: and

a 'coil sarin(r 34 is sleeved on said )ull-rod between said head and the inner end of said yoke and thus causes the rod to move with said yoke while permitting relative, longitudinal sliding movement between said pullrod and said link. rlhe portion of the pullrod 32 located inwardly of the link 30 is slidably supported in alined openings provided therefor in tongues 35, 35a that project outwardly from the vertically disposed web portion of the channel-shaped bracket 29; and a thimble 86 is threaded on the inner end of said pull-rod and serves to secure one end of a cord or cable 37 thereto.

The cord or cable passes upwardly around an idler pulley 38 journaled on a horizontal pin 39, which projects outwardly from the rear wall of the box 1, and is then wrapped one turn about a driving pulley 40 mounted on the lower sprocket shaft 11 and has its end attached to a vertical anchor rod 41 by means of a thimble 42 threaded on the lower end thereof. The anchor rod 41 is located above the driving pulley 40 with its lower end portion slidable in an opening provided therefor in a. bracket 43 secured to the rear wall of the box 1. The upper end of the anchor rod 41 is suspended from the upper end of the bracket 43 by means of a coil spring 44, which serves to pull the cord or cable 37 upwardly with the fastening thimble 42 at the lower end thereof in abutting relation to the lower end of said bracket. With this arrangement, as the typewriter carriage nears the end of its return movement, it engages the free outer end of the operating arm 27 and swings the same in a direction which will pull the cord or cable 37 outwardly against the tension of the cord supporting spring 44 and thus rotate the drive pulley 40 on the lower shaft 11.

A roller clutch mechanism is provided betweenthe lower shaft 11 and the drive pulley 40 thereon to cause said shaft to be rotated by said pulley in a direction which will cause the outer stretches of the sprocket chains 2O to travel downwardly. Said clutch vmechanism preferably comprises rollers 45 mounted in a series of circumferentially spaced pockets 46 provided therefor in the inner periphery of the drive pulley 40. The clutch rollers 45 roll on a suitable racewa-y 47 provided therefor in a colla-r 48 which is pinned on the lower shaft 11 and encircled by the drive pulley 40. The roller pockets 46 are smaller at one end than at the other, and the rollers 45 are yieldably held in the small ends of said pockets by means of spring-pressed pins 49 slidably mounted in small apertures opening into the large ends of pockets 46. By this arrangement, when the drive pulley 4() is rotated by an outward pull on the cord or cable 37, the rollers 45 will bind or wedge between thesmall ends of the pockets 46 andthe raceway 47 on the collar 48 pinned on the lower shaft 11 and thus ley 40 in the opposite direction and returning the parts to their normal positions; but no motion is imparted to the shaft 11 by reason of the rollers being moved against the pressure of the spring-pressed pins 49 towards the wide ends of the pockets 46 and thus preventing said pulley from being clutched to said shaft. The parallel sprocket shafts 11 and 13 and the chains 20 connecting them are held against movement, except when the operating arm 27 orknob 15 are manipulated, by means of a suitable friction brake which engages the lower shaft 11. Said brake comprises a pair yof brake shoes-50 adapted to grip opposite sides of acollar 51 on the lower shaft 11. One of the shoes is rigidly secured to the rear wall of the box 1 and the other shoe is held in yielding engagement with the collar 51 on the lower shaft 11 by means of coil springs 52 that are sleeved on screws 53 passing through the two shoes with their ends in abutting relation to the bottoms of recesses 54 in the outer shoe and nuts 54a threaded on the ends of said screws.

The outward sliding movement of the pullcalled a selector bar; and theV outer abutment 57 is adapted to abut against a stop formed by the tongue 35 of the outer end of the chan- Y nel bracket 29. rlhe abutments 55, 56 and 57 are positioned on the pull-rod 32 so that, when the respective abutments engage the stops pro-vided therefor, the outwardly sliding movement of said pull-rod is limited to the amount necessary to obtain a single, double or triple line spacing movement of the marker 25. The selector bar 58 is mounted for vertical sliding movement in notches provided therefor in the top and bottom flanges of the channel-shaped bracket 29 and in the bottom of the box 1. The selector bar 58 is provided at its lower end with cross-pins 59 for lifting the bar; and it is also provided with a pointer 60, which extends upwardly outside the outer front cover 2 of the box 11 with its upper end terminating adjacent to three lines or graduations marked 1, 2 and 3, respectivelvon said cover. The selector bar 58 is provided with a horizontal opening 61 through which the pull-rod 32 extends. The upper portion of the opening is of a width adapted to permit the pull-rod, but not the intermediate abutment 56 to slide therethrough; the intermediate portion is of? a width to permit the pull-rod and also the abutment56 to slide therethrough,but not the.

abutment and theilower portion of said opening is of a width adapted to .permit both the intermediate abutment 56 and the slightly larger inner abutment 55 to pass therethrough. The selector plate 58 is yieldably heldin each one of the three positions of its vertical movement by means of a ball 62 mounted in a pocket 68 provided therefor in the web of the channel bracket 29 andis adapted to seat within vertically spaced V- shaped ynotches 64formed in the rear edge,

of said selector bar. The ball 62 is forced into the notches 64 by means ofl a coil spring 65 located in the pocket 63. By this arrangement, the ball 62 is forced into one of the V-shaped notches 64 in the selector bar 58 in the three positions of adjustment thereof and thus serve to releasably hold said selector bar 1n position.

By the arrangement described, when it is desired to adjustV the marker 25 so that during each step of its movement it will -move a distance corresponding to the single line spacing of a typewriter, theselector bar 58 is adjusted to bring the end of its pointer 60 opposite the line marked 1 on the front cover plate 2 of the box.1,-thereby causing the small upper end of the opening 61 in said selector bar to be brought into a position opposite the pullrod 32 and thus enabling said bar to serve as a stop for the intermediate abutment 56. When -it is desired to obtain a movement of the lmarker 25 corresponding to the double line spacing of the typewriter, the selector bar 58 is raised far enough to bring its pointer 60 Opposite the graduation marked 2 on the front cover` plate of the box, thereby bringing the wider intermediate portion of the opening 61 1n said selector har in line with the pull-rod abutments and thus permitting the pull-rod to move outwardly until the inner abutment 55strikes the selector bar. marker 25 corresponding to a triple line spacing of the typewriter is obtained by bringing the upper end of the selector bar pointer 60 opposite the graduation niark 3, thereby bringing the greatest width of the opening 61. in the selector bar in line with the pull-rod abutments. VViththe parts in this position therinner and intermediate abutm'ents 55 vand 56 pass through the opening in the selector bar and the outer abutment 57 isV permitted to travel outwardly vwith the pull-rod until it Movement of the* strikes the tongue 35, this outward travel of Obviously, the hereinbefore describedcopyholder admits of considerable modification without departing from my invention.
