To all @07mm t may concern: for securing the copyholder at the rear of a Be it known that I, GEORGE C. HOHEIN, a typewriter frame, and 55 citizen of the United States, residing at Fig. 9 is a similar view showing another Clarendon, in the county of Arlington and means for securing the copyholder in po- State of Virginia, have invented certain new sition.

and useful Improvements in Copyholders The typewriter, indicated at 1, may be of for Typewriters, of lwhich the following is any make now on the market and in itself 60 a specification. forms no part of by invention.

My invention is a copyholder for use in In carrying out the present invention, I

At the lower corner writer and my improved copyholder in poof each standard 8 is a `foot member 13 which sition for use; extends rearwardly and downwardly `from 95 Fig. 2 is a side elevation ofthe copyholder; the standard and has pivotally mounted Fig. 3 is a detail view in side elevation of thereon at its inner side a toe or shoe 14 proa portion of the copyholder viewed from the vided with a series of openings 15 thereside opposite that shown in Fig. 2; through disposed concentric with its pivot 16 Fig. 4 is a rear elevation with the back and any one of which may be engaged by a 100' plate of the housing or frame removed; set screw 17 mounted in the foot member Figs. 5, 6 and 7 are vertical sections upon 13.v The toe or shoe 15 has secured toits the lines 5 5, 6-6 and 7-7, respectively, of -free end a pad 18 of rubber, leather or other Fig. 4; cushioning material which is adapted to rest Fig.L 8 is a view, partly in horizontal secupon the surface of the typewriter desk or 105 ltion and .partly in plan, showing one means table and thereby support the copyholder mediately in rear of the ty at the two sides of the eopyholder andare connected by a brace rod 19 which receives the ends of the pivot screws 16 and also by a bracing frame 2O which is disposed imewriter and is provided at its ends imme lately adjacent frames of various widths.

i somewhat below the up p lip the standards with forwardly offset portions 21 adapted to bear against the rear post 22 of a typewriter frame. At one end the bracing frame 20 is provided in its Voffset 21 with a horizontal slot 23, the purpose of which will 'presently appear. In connection with each offset portion 21, I employ a clamp 24 which. may conveniently be in the -form of a plate adapted to overlap the inwardly projecting flange on the rear of the typewriter frame and having a rearwardly projecting 25 at its inner end to bear against the adjacent offset 21. A set screw 26 is mounted in the offset 21 and has threaded engagement with the clamping plate or. bracket 2,4, as shown clearly in Fig. 8,- whereby, if the screw be turned home, be'irmly secured to the typewriter frame. The slot 23 permits the set screw therethrough to be adjusted toward or from the adjacent side of the typewriter frame and thereby accommodates typewriter This manner .of securing the eopyholder to the typewriter frame may be employed in all makes of machines where the rear portion of the typewriter frame is open or has an open space through which the brackets or clamping plates 24 may be fitted and adjusted. Some typewriters, however, are entirely enclosed at their rear sides and one instance of such construction is shown at 27 in Fig.y 9. In order that the eopyholder may be connected with such typewriters, the ends of the bracing frame 20 are extended so as to projectlaterally beyond the sides of the typewriter, as shown at 28, and have openings formed therethrough to receive the shanks hooks 30 which are adapted toengage around the posts or rear columns of the typewriter frame, nuts 31 being fitted on the rear ends of said shanlis to be turned home against the projecting ends 28 of the bracing frame to secure the eopyholder in place. By pivotally adjusting the toes or shoes 14, they may the eopyholder may be made to accommodate various makes of typewriters and be connected thereto notwithstanding variations in the vertical dimensions of the back plates of the typewriter frames.

As shown most clearly in Figs. 5 and 6, the upper edge of the front plate 2 is disposed er end edges of the side plates 3, a line-disp aying openingbeing thus produced above the front plate, the upper margin of said opening being defined by the eopyholder will 26 inserted be set relatively higher or lower so that a cross bar or plate 32 which is 4secured to and extendsbetween arms 33 and 34 which are mounted upon the shaft or journals of the feed roller 35 to rock concentric therewith. Spring fingers 36 are secured upon the bar 32 and project rearwardly from the upper edge thereof so that the copy will b e directed rearwardlyl as it isfed through the eopyholder. The arm 33 is formed integral 'with a handle member 37 projecting up-A wardly at the left side of the eopyholder and also integral with a stop arm 38 which extends ,downwardly and somewhat forwardly, as clearly sho-wnin Fig. 3. The lower end of the stop arm 38 is provided with a plurality of openings or sockets 39 byv a stud 4() on the' adapted to be engaged upper end of a leaf spring'41 secured upon the adjacent side plate 3. By manipulating the handle 37, the arms and 34 may be rocked so as to set the bar 32 closer to or farther from the upper end of the front plate 2 and thereby vary the width of the line-displaying opening, the arms being held in the set position by the stud 40 en gaging the socket 39 presented thereto in an obvious manner. The apparatus is thus easily adjusted to the width of the lines of copy.

At the upper front corners of the side plates 3 are secured brackets 42 having rests 43 secured to their upper ends, these rests being provided with forwardly projecting stop lugs 44 against which the ends of a lens 45 may abut whereby endwise movement of the lens will be prevented. end of cach rest 43 is provided a hook or cup-like support 46 in which the lower core' ner of the lens is engaged whereby the vlens willbe firmly supported by and between thev rests and at the upper end of each rest is a leaf spring 47 projecting forwardly over the rests and having its free end formed into a hook or shoulder 48 adapted to engage over the upper edge of the lens at the end thereof and tagainst the front face of the lens so as tociectually retain it in place. The extremity of this spring 47 is formed into an upstanding lip 49 whereby it maybe easily released from the lens to lOl) ` At the lower lib permit the removal thereof for cleaning and also te facilitate the assembling Aof the lens with the eopyholder.

The'feed roller 35 which has been mentioned is carried by trunnions or journals 50 which are rotatably mounted in the side plates 3 immediately adjacent thel upper ends 'thereof andi-.1n the central vertical planes of the upper portions of the Side pla-tes. The roller is preferably faced with rubber or other 'friction material 51 where` by a goodgrip may-be obtained upon the copy, and supported by the upper ends of the side plates 3 and extending between the same is a trough 52 which is arranged to pass below the feed roller and guide the' copy so that it Will be held thereto and be caused to Ltravel around the same. `Open ings 53-are formed in the trough 52 in front and in rear of the transverse center thereof and friction rollers 54 are arrangedto pass through the said openings and cooperate with the feed roller to yieldably grasp the copy so that, when the feed roller is rotated, the copy will be fed through the copyholder. The rollers 54 are carried by rods 55 having their ends mounted in horizontal' slots 56 provided in the side plates 3 adjacent the upper ends of the same andA leafsprings 57 are'arranged to have their upper free ends bear against `the rods 55 so as to press said rods toward the center of the machine to bear against the feed' roller at opposite sides .of the vertical plane of its axis. At the upper end of the back plate 4 is formed an inclined shelf 58 which is so disposed 'that its plane passes into the trough 52 between the rear edge of the same 'and the feed roller, and manuscript or other matter to be copied will be guided `into thetrough so as to be gripped within the trough by and between the feed rollers and the presser rollers 54 cooperating therewith, the manuscript or other copy being supported by the shelf 58,I as' will be understood. When the copy is fed into the trough, it will I pass under and around the feed roller and ist. As shown, the rollers will emerge between the feed roller and the bar y32 so that it will not drop over the freno of the copyholder and between the same and the typewriter to the annoyance of the copy- 54 and the springs 517 are disposed equisdistant from the vertical plane of the axis of the feed roller 35. In said vertical plane, a vertical slot 58 is formed in each side plate 3 to receive a screwor bolt 59 which 'engages the lower` end of a `cam slide 60 and connects the same with the lfront end of a rocking arm 6l secured to the end of a rock shaft 62 mounted in and extending between the side plates 3 adjacent the rear edges thereof and above the lower ends of theleaf springs 57. The cam slide 60 is a substantially Yshaped plate disposed between the end of the feed roller and the adjacent side plate 3, the notch 63 in the upper end of the slide spanning the trunnion or journal of the feed roller and the inclined .side edges 64 of the cam slide bearing upon lugs 65 on the ends of the rods 55. In the upper ends of the cam slide are vertical slots 66 which are engaged by retainingf guide screws 67 inserted therethrough into the side plates so that the -cam'slide will be properly guided and held to a rectilinear path. These screws also prevent the cam slide rocking laterally away from the side plates and creating unnecessary wear upon the ends of the feed roller or otherwise tending to choke or detract from the eliiciency of the apparatus. It

'will now understood that normally the cam slide 1s in its raised position, shown in ,F1g. 6, so that the rollers 54 are held in engagementwith the feed roller 35 or against copy passing under andaround said roller.

If it `be desired to remove the copy or insert fresh copy, a downward movement is imparted to the cam slides so that they will ride on and between the lugs 65 and thereby spread said lugs and the rods 55 apart in opposition to'the springs 57, consequently carryingthe rollers 54 out ofl contact with the feed roller and to points where they will not protrude through the troughv 52. A copy may be inserted while these rollers are-held in this retracted or depressed position and after the copy has been properly engaged 'in or through the trough the springsmay be freed so as to' again press the rollers into operative position. The springs 57 may be secured in any desired manner but avery convenient method plates 3 and rivet or otherwise secure the ends of the springs to these tongues, it being understood that the frame plates of the housing are preferably of sheet metal.' To rock the shaft 62 so that be withdrawn froln the feed roller, I secure to the right hand end of the said sha-ft a lever or arm 69 which extends upwardly and forwardly and is equipped at'its upper extremity with an outwardly extending finger rest .70, this finger rest being slightly con# cave so that it may be comfortably engaged by the finger or hand of the operator. To

facilitate the placing of the copy within the' eopyholder and the bringing of the first line .of the copy into position in rear of and across the line-displaying opening, a `milled head or knob 7l is secured upon each of the journals 4or trunnions 50 of the feed roller.

Upon the right hand journal ortrunnion of the feed roller is secured a ratchet disk 72 disposed at the outer side of the adjacent side plate4 of the housing, and a springpressed dog 73 is pivotally mounted upon the adjacent side plate and adapted to engage the ratchet wheel grade movement of the same; It will be noted, upon reference' to Figs. 2 and 7, that` I which. I employ is to strike tongues 68 inwardly from the sidev 72 to prevent retrothe rollers 54 will feed the copy as the lines are which extends downwardly at the side of tween its ends upon the housing and has its lower end pivotedl to the rear end of' a lever 77 fulcrumed bethe side of the housing, a spring 78 being attached to said lever and the side plate so as to normally hold the rear end of the lever in its uppcrmostvposition. To limit the movement ef this lever 77 a stop bracket 79 is secured upon the side plate 3, which bracket is in the form of a plate having its ends turned outwardly to form stop lugs 80 projecting into the path of the lever, as will be .understood upon reference to Figs. 2 and 4. To the front end 'of the lever 77 is pivetally attached the upper end of a connecting bar 81 and to the lower end end of an operating lever 82 whicli'is fulcrunied upon the adjacent standard 8 and projects forwardly at the side of the typewriter whereby its front end willbe arranged adjacent the typewriter-keys and may be equipped witha button or key 83 so The conthatit may be easily operated. neeting'loar 81 is preferably of a telescopic or extensible construction, consisting of two similar members, one provided with longi-` tudinal slots 84 through which stud bolts may be inserted to pass through the other member and be engaged bysleeve nuts 85 whereby, when the nuts are turned home,

the two members of the connecting bar will` be firmly secured in a set relation. The device is thus easily adapted tothe height of "t the typewriter or other peculiarities ofI construction in the typewriter frame.

The width of the head of the pawl 74 is greater than the thickness of the ratchet 72 so' that a gage or stop lever 86 may be brought into play at times to hold the pawl out of engagement with the ratchet and also to regulate the extent to which the ratchet will be turned by the engagement of the pawl. 'l

his stop or gage consists of a plate mounted loosely upon the journal of the feed roller between the ratchet and the side plate of the housing and it is formed with an edge 87 adapted to ride under the head of the pawl and hold the same out of engagement with the ratchet, as will be understoodupon reference to Fig. 7. A handle 88 is provided .and rises from the edge of this stop or gage 86 whereby the stop or gage plate may be rocked upon the trunnion of the feed roller to cause more or less of the edge 87 to project under the pawl. A series of openings or sockets 89 is provided in the inner face of the plate 86 and any one of these sockets or openings may be engaged by a stop pin 90 carried by the inner end of a leaf spring 91 secured upon the adjacent side plate, as shown. The engagement of tlie`pi1i 90 in one of the sockets 89 will yieldably hold the stop in the position of this bar 81 is pivoted therear vholder easily as the copying 'be gripped by and between the same.

`movement of the pawl 74V so that said pawl will be inoperative and will not impart movementl to the feed roller whether or not the operating lever 82 should be actuated. his position of the stop plate 86 is given it when copy is being insertcihand it l'will be noted that the pawl 74 will then have no linfiuence upon the ratchet 72 so that the feed roller may be readily rotated in veither direction by manual manipulation of the knobs 71 so as to bring the first line of the copy-into proper position at the line-displaying opening belowv the edge of the bar 32. When the stop plate 86 is swungfor- "wardly, the edge 87 will not extend through lthe entire range of movement of the pawl and, consequently, the pawl j will ride on the edge 87 through a partpnly of its movement, engaging the ratchet 72 during the remaining portion of its movement to actuate the feed roller. The extent to Which the feed roller maybe turned each time the operating lever 82 is depressed will,` consci quently, be easily regulated so that the line by line-feeding of the copy will-be effectually accomplished. By properly adjusting the position of the bar 32 and the feeding of the -feed roller through the action of the pawi 74," the-feeding of the copy will be regu! lated to conform to the size or width of the lines of copy as well as to the distance be` tween the lines. 1

Freni the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided a very compact, easily operated and durable copyholder which may be readily set up and soy attached to any typewriter and will support copy so that'it may be read by the copyist /without eye strain and fed through the progresses. It will be understood that the copy,'indicated at'100, is'passed downwardly over the shelf 58 so as to enter the bight between the feed roller`35 and the presser rollers 54 so` as tlo t will then pass upwardly in rear of the bar 32 and be guided backwardly by the fingers 86 carried by said bar. Vhen one line of the copy has been copied, pressure is applied to the lever 82 in the same manner that the keys of the typewriter are operated, and this pressure vwill cause an upward movement of the connecting bar 81 so that the lever 77 will be rocked and the link 76 drawn downwardly causing the plate or pawl. carrier 75 and the pawl 74 mounted thereon to rock downwardly and actuate the ratchet wheel 72 through one step. When the pressure upon the operating lever 82 is removed, the spring 78 at once returns the parts to the initial normal position. It will be readily noted that the housing' completely encloses housing, a feed roller mounted in the upper per end of .end of said housing, means for holding copy to said feed roller whereby rotation of the roller will feed the copy, the copy being visible immediately above the front of the housing, means for rotating the feed roller,
