COPY-HOLDER.

Specification of Letters Patent.

Patented May 22, 1917.

Application filed October 30, 1911. Serial No. 657,409.

To all whom/ it may concern:

Be it known that I, WALTER E. BARNARD, a citizen of the United States, residing in Hartford, in the county of'Hartford and State of Connecticut, have invented certain new and useful Improvements in Copy- Holders, of which the following is a specification.

My invention relates to copy holders, and is particularly related to those which are mounted on the frame of the typewriter.

In the preferred form herein illustrated, it comprises a bracket which is held on the front of an Underwood typewriter by the same screws which hitherto have been used to hold on the front plate of the machine. A clamp on this bracket supports a table on which the copy lies flat and beneath which are mounted rolls which project to or slightly above the surface of the table. Above these are mounted other rolls which cooperate with the first rolls in moving forward the copy. These upper rolls may be turned either by a knob in either direction, or by means of a handle working through a pawl and ratchet wheel, in the direction in which it is desired to normally feed the copy. This handle automatically moves forward the copy the space of one line every time the handle is pressed. 7

There may be provided also a guide for the eye to follow, which may be adjusted means of a knob 14 at one end of the shaft.

across the table, and which is clamped to a rod at the side of the table in any desired position. I

Among the advantages of my invention is that the copy holder is held on by the same screws which hold on the front plate of the Underwood typewriter, so there are no loose parts to be lost and only an ordinary screw driver is needed to put the holder in place. The work is positively held at the right dis tance from the eyes in the copy holder, and is always moved forward just the right amount for each line. The holder itself is easily swung back on its clamp out of the way when not in use.

Other features and advantages will hereinafter ppear.

I 16 from one move forward the paper between the rolls In the accompanying drawings,

Figure 1 is a perspective view of my improved copy holder, showing it attached to the front of a typewriter, most of the typewriter being broken away for the sake of clearness.

Fig. 2 is a rear view, showing the position of the rolls.

Fig. 3 is a view showing the ratchet when it has just moved forward the work one linespace. Y

Fig. at shows the ratchet and other parts when the pawl is disengaged from the ratchet.

Fig. 5 is a section showing how the guide is attached to its rod.

1 is a suspension bar on which are mount ed at each end brackets 2 and 3 carrying a table 4:, on which the matter to be copied is laid. Other brackets 5 and 6 rise at the ends of said suspension bar, and serve as bearings for the shafts of upper rolls 7 and lower rolls 8. The lower rolls are loose on their shaft 9 and are spaced along it at intervals by spacing tubes 10. This shaft is mounted in elongated bearings 11 in which it is free to play, and is pressed normally upward toward the upper portion of said bearings by springs 12, so as to bear against the bottoms of the upper rolls 7 The upper rolls aforesaid, are fast on their 'shaft'13, and are adapted to be turned with it by On the opposite end of the shaft 13 is a loose wheel'15, carrying a handle 16 and a pawl 17 This latter pawl engages with a ratchet 18 on said shaft 13, and so, whenever the handle is moved, turns said shaft 7 with its rolls in onedirection.

The movement of the handle 16 is limited by stops 19 and 20 located on the idle wheel, which are arranged to strike against a pin 21 on the bracket 5, and these stops are so arranged that one full throw of the handle limit to the other,.will exactly one line-space.

The pawl 17 conta t with the ra chet Wh el y means is drawn down normally into a spring 22 anchored to the pin 21, and on the end of the pawl is arranged a cam surface 23, which isadapted whenever it strikes pin 21, to raise said pawlclear of the ratchet wheel, so that the shaft and rolls may be turned freely by knob let in either direction.

In order to guide the eye in reading the copy, a guide 24 extends across the table 4:, and is mounted on a rod 25 by means of a clamp 26, so that it may be adjusted in any convenient position. This clamp is arranged so as not to mar the surface of the rod 25, and comprises a main body 27 in which a screw 28 moves freely carrying on its end a ring 29 embracing the rod 25. This ring 29 may be drawn outward by means of a thumb nut 30 working on the screw 28, and bearing against the main body of the clamp, to lock the guide on the rod.

The rod 25 itself is mounted in a small bracket 31 on bracket 3, and has a flat side 32 which bears against the body of bracket 3, so as to hold the rod substantially parallel to the table. The rod 25 is so arranged that it may be easily slipped in and out of the small bracket 31, so that it may be removed whenever not needed.

In order to prevent the paper from catching beneath the rolls or in the supporting mechanism of them, the upper end of the table is extended as by fingers or'strippers 33 passed between the rolls, so as to form strippers to carry the paper clear of them. Also an upper shield 34 is provided to cover the upper rolls, and to keep dust out of them and paper from getting entangled with them.

In Fig. 4, a sheet of paper is shown at 35 lying between the rolls passing under the guide 24 and outwardly beyond the strip pers 33.

The rolls themselves are preferably covered with a layer of cork composition as shown at 36 which enables them to grip the paper easily.

It will therefore be apparent that it is impossible for the paper to get entangled in the mechanism and the copy will require no attention beyond the operation of the handle when once properly set.

To best use my copy holder, it is attached to the typewriter. For this purpose, the suspension bar 1 is extended to form a flat tongue 37 which is gripped in a socket formed by the flat arms 38 of a bracket 39. These arms are made resilient by extending a slot 40 from the socket so that the arms 38 can be closed on flat tongue 37 by means of a thumb screw 41. The suspension bar is thus restricted to swing in a horizontal plane. An arm 42 of said bracket 39 extends upward along the front of the Underwood typewriter, and is pierced with holes through which the screws 43 may pass. These screws are the ones that are ordinarily employed to hold the front plate 14: on the frame of an Underwood typewriter. To attach the copy holder the screws are removed, the bracket placed in position in front of the plate, and. the screws then reinserted through both bracket and face plate.

The bracket arm 42 is preferably somewhat cut away at 4-6 to give free access to the lock release button -17.

It will be seen that my copy holder may be easily adjusted at the most convenient angle for work, or may be swung one side completely out of the way, as shown in Fig. 1, and is easily locked by screw ll in either position. Furthermore, if it is removed from the machine for any purpose, there are no loose parts of either machine or holder to lose while stored.

- Variations may be resorted to within the scope of the invention, and portions of the imj'n'ovements may be used without others.

Having thus described my invention, I claim:
