COPY-HOLDER.

App1ication filed June 8, 1916.

To all whom 2'2? may concern:

Be it known that I, l/VILLIAM B. RHQADS,

a citizen of the United States, and a resi' dent of the city and county of San Francisco, State of Callforma, have invented a new and useful Copy-Holder, of which the following is a specification.

My invention relates to means for holding data which is to be copied.

An object of my invention is to provide a copy holder in which the indicator is're turned automatically from the bottom to the top of the copy.

Another object of my invention is to provide acopy holder which maybe folded about the machine to which it is attached.

Another object of the invention is to pro vide a copy holder. in which the indicator adjustable to different thicknesses of the copy pad.

Another object of the invention is to provide a copy holder which is attachable to typewriters, linotypes, monotypes and similar machines and in which an indicator is moved a predetermined amount by depressing a key.

Another object of the invention is to provide a copy holder in which the spacing movement of the indicatoris adjustable to correspond with the spacing of the lines of the copy.

The invention possesses other features of advantage some of which, with the foregoing will be set forth in the following de scription of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a side elevation of my copy holder, showing its application to an or dinary typewriter.

Fig. 2 is a front elevation of the copy holder apart from the typewriter.

Specification of Letters Patent.

Serial No.102,468.

Fig. is a fragmentary view on anenlarged scale ofa portion of my device.

Fig. 4 is a detail onan enlarged scale showing a portion of the mechanism.

Fig. 5 is a fragmentary sectional view taken oaths-line 55 of Fig. 3.

Fig. 6 is a detail on an'enlarged scale showing a portion of the mechanism.

Fig. '7 is a section taken on the line 77 of Fig. 6.

The copy holder of my invention is apdesired to maintain the matter which is to be copied in a convenient position before the eyes of the copyist, but in this application, I will show and describe my invention as it is used in connection with a typewriter.

My invention includes a frame comprise Patented Get. 30, 191W.

plicable in any circumstances in which it is ing the upri ht members 2, and the member 3 which is adapted to be rigidly secured to i a typewriter, preferably by clamp members 4: and The exact manner of securing this frame to the frame of the typewriter is not" important. The essential thing is that it shall be rigidly secured to the typing ma chine and in eflect an integral portion thereof.

The copy holder in which the copy is retained is pivotally mounted upon the frame 2-2 so that it may be folded down over the top of the typing machine when the latter is closed up in its desk. The copy holder 7 and having a ledge 8 at its lower front edge. At the lower rear edge of the plate 7 a sleeve 9 is mounted on brackets 12 and 13 which securely attach the sleeve to the plate. On the outside of the brackets the sleeveextends a short distance and these extensions form journals, bearings for which, 14, are arranged at the top of the frame members 2. The plate 7 is therefore adapted to be turned in the bearing-s14, and a stop-15 is arranged on one of the frame members 2 to'limit the backward turning of the plate.

Arranged in the sleeve 9 is a shaft 16, and a sprin'gl'r', coiledabout the shaft and attached at-ones end'to the sleeveand at' the preferably consists of a thin, metallic plate a other end to the shaft, resists the turning of the shaft in the sleeve. Fixed to the outer end of the shaft 16 is a sprocket wheel 19 and a ratchet 21. A U-shaped member is disposed upon the side of the plate 7 above the sprocket 19. At the top of this member is mounted another sprocket 25 and a chain 26 passes about the sprockets, its front reach 26 being disposed in the member which therefore acts a channel or guide in which the front reach of the chain 26 slides when the lower sprocket 19 is turned. 7

Means are provided for turning the ratchet wheel intermittently through a certain arc of revolution. A rocker 28 is loosely mounted upon the end of the shaft next to the ratchet 21. The rocker is retained in position by means of the washer 31 hearing against a shoulder on the shaft and the thumb nut 38 threaded on the shaft tight against the washer. The rocker is oscillated by means of the link pivoted thereto and to a lever 36 pivotally mounted at 37 upon the frame extension 38. The forward end of the lever 36 carries a key 39 preferably suitably designated, and disposed adjacent the typewriter bank of keys in a' conveniently reached position. A spring 4C1 operates to return the lever and rocker normal position after each depression of the key, and a stop or loop through which the lever passes limits the maximum movement of the lever. The rocker 28 carries a pawl 4A- which is retained in engagement with the teeth of the ratchet 21 by the spring 45. The teeth of the ratchet, and the rocker are so disposed that depression of the key 39 effects a vmovement of the ratchet in a direction such that the travel of the outer reach of chain 26 in the channel 24: is from the top toward the bottom of the plate 7.

llleans are provided for varying the amount of movement of the ratchetwhen the key is depressed. A. portion a? of the chan nel Q-fi is extended rearwardly between the sprocket l9 and the ratchet 21. Preferably it encircles the shaft and is of circular form slightly larger than the ratchet 21. On the shaft 16 between the plate 47 and the ratchet 21 is loosely disposed a disk 51 preferably about the same size as the plate 47. Several holes are formed in the disk 51 on a circle concentric with the shaft 16 and a spring pressed knob 52 carried by the plate 47 is adapted to engage in these holes so that the disk is prevented from rotating unless a certain amount of pressure is exerted to turn it; when the knob is disengaged from the hole in which it happens to be ly ing. A portion of the edge of the disk 51 is formed with a flange 54: which extends across the teeth of the ratchet 21. The

flange is so placed that in a portion of the recovery movement of the rocker 28 the pawl ii rides up upon the flange and is therefore drawn out of engagement with the teeth of the ratchet. By var ing the position of the flange the pawl li may be kept in contact with it for various proportions of the operating movement of the rocker and allowed to engage the ratchet only for the balance of the movement. The spa ing and position of the holes in the disk 51 are such that the disk, and hence the flange, is held in predetermined relation to the movement of the rocker so that the amount of movement imparted to the ratchet 21 by the rocker may be controlled as desired. At the front, the disk is provided with a pointer 56, which in conjunction with scale 57 fixed upon the lower end of the channel provides means for determining the position of the disk. The disk 51 is provided with an ear 58 which serves as a handle for shifting it. A. spring pressed pawl 61 pivoted to the side of the channel engages the ratchet 21 on the recovery movement of the rocker 2-8 and prevents the spring 17 from turning the shaft,

sprocket and chain back to first position,

Slidably arranged upon the front of .the channel 24c is a block ea. The block is attached to the chain 26 on the inside of the channel through a slot disposed in the front face of the channel and any movement of the chain 26 upon 'thesprockets is accompanied by a corresponding movement of the slidable block. Hinged upon the block 6% between the lugs 65 thereon is a socket 66 and in the socket is arranged a line indicator. 67 which overlies the plate 7 and any copy which is held thereon. provided with graduations similar to those on the spacing guide on the front of the typewriter. The indicator is preferably reversible in the socket to accommodate a very thick copy pad thereunder. A spring 69 tends to turn the socket inwardly, thus keep ing the indicator pressed against the copy.

When there is need, the indicator may be swung outwardly about its pivotal mounting in the block against the resistance of the spring 69.

Preferably the parts are so disposed that when the indicator is in its topmost position there is a'slight tension in the spring 17. It is now apparent that successive depressions of the key 39 effect intermittent rotation of the ratchet and shaft and intermittent movement of the chain 26 and the attached indicator, the latter moving from the top of the pla'e 7 toward the bottom in steps determined by the effective throw of the rocker 28 which as already explained is determined by the setting of the disk 51.

If the disk is set to l on the scale, each.

Preferably the indicator is I depression of the, key. lowers the indicator one line space. Ifthe disk is set to 3 on only to set the disk for the spacing of the copy. A depression of the key when a line is finished moves the indicator to the next line.

,Means are provided for automaticallyreturning the indicator to the top or first position when the limit of its advance across the copy support 7 is reached. The lower part of the block 64: is provided with a slanting surface 72 and the pawl 61 is provided with a roller 73 mounted on a pin rigidly fixed in the pawl. The rollere-Xtendsacross the channel 2 in a position to be engaged by the wedge surface 72 when the indicator is at its lowest point. As the wedge passes under theroller, the latter is forced up, and the pawl 61 freed from the ratchet 21. A spring pressedlatch 74 is arranged above the pawl 61 and as the pawl is lifted out of engagementwith the ratchet, the latch catches and holds the pawl in the disengaged position. Except for the engagement of the pawl id on the rocker, the spring 17 would now cause a recovery movement of the shaft and chain, carrying the indicator back to the top ofthe plate, and this occursas soon asthe pawl ii is'lifted off of the ratchet by the flange 5% during the recovery movement of the rocker which leaves the shaft free to rotate. A rubber stop 7 5 at the top of the channel 24 receives the impact of the upwardly moving block 6% and makes the recovery practically noiseless. In order to release the latch 74 from the pawl, so that the pawl may again engage the ratchet on the downward movement of the indicator, a trip 76 issecuredto the chain at a point which will engage the pin 77 and release the latch just as the indicator reaches its top position. The pawl 61 is provided with a short projecting rod 78 whereby it may be disengaged from the ratchet by the fingers at anytime.

The top of the copy support 7 is provided with a clamp for holding the copy. The clamp preferably consists of a rod 81 pivotally mounted at its ends and offset between the ends, so that different thicknesses may be held by it. Preferably rubber friction pads 82 are provided on the offset portion. The clamp is pressed against the work by means of a spring 83 arranged at one end of the rod 81.

If it is desired to backspace the indica tor, that is, set it back to a higher line, the pawl 61 is moved out of engagement with the ratchet wheel, the thumb nut 33 being frictionally engaged by the fingers and thumb, so that the backward rotation ofthe shaft and sprocket maybe controlled. ;The nut 33,:and attached shaft is allowed to turn in theifingers until the indicator reaches the desired height, where it is stoppeda'nd the latch 7% released from the pawl which then engages the ratchet and prevents further backward movement.

It will be understood from the above explanation thatt-he plate 7 may be folded down over the machine about an axis coinciden-t with the axis of the shaft 16 and for this reason, none of the working parts are disarranged or need to be detached because of said folding.

1 11102188 it is desiredyto start the feed of the indicator from a point below its topmost position, the thumb wheel or nut :may be rotated by the fingers to bring the indicator to the desired position.
