6 Claims.

Tlf'ijepresent' invention consists of a copyholder embodying improvements over my former Patents No'. 1,939,671,13eeember I9-, 193 3a|nd No. 2,162,706, June 2U, 1939. l

Infthe present' invention I' providenovel drive means for the feed rol-1erv effecting more delicate spacing of the copy, yet retaining-the desirable spacerf bar and; adjusting means;

I 'haver found that .itA is desirable at times; to need; copy more: or:` less than. a. certain number of? set; spacestetwliichy my previous` machines arellimited. It; is consequently the desideratum of the: present. invention to` provide a copyholder wherein the copy may be fed to any extent de-` sirediby the operator down to the smallest fraction of an inch, thereby permitting universal spacing.

The means employed in the present invention for effecting universal spacing has been found, after much experiment, to be extremely accurate and sensitive and is capable of facile adjustment to change the degree of spacing at the option of the operator.

Other objects of the invention will be apparent from the following description of the invention, taken in connection with the accompanying drawing, wherein Fig. l is a perspective View of a copyholder',

Fig. 2 is a vertical sectional View showing to advantage the feed roller drive means of the present invention, the latter being shown in side elevation,

Fig. 3 is a detail fragmentary sectional View taken on the line 3-3 of Fig. 2, and showing to advantage the improved axle of the present invention and manner of mounting the same,

Fig. 4 is a detail fragmentary sectional View taken on the line 4 4 of Fig. 3 showing the mannerof mounting one end of the axle in one of the casing ends,

Fig. 5 is a perspective view of the axle per se, and

Fig. 6 is across sectional view taken on the` latter, is an axle I0, the ends of which are attfened, as indicated at II, andmounted in complemental slots I2, formed in plates I3, the latter being mounted in theV ends or the sides of the casing.` A feed roller I4- issleeved over theY axle Ill and is spaced from the latter by an annulus I5. The annulus is formed on the axle approximately midway itsends, as illustrated to advantage in Fig. 3. To preventA tilting of the endsv of the roller onv the axle ISI, I equip the latter with protuberances I6, one of the latter being formed adjacent each terminal of the axle.

IPaper `feed-ringsv IIT are mounted on the roller I4,

portions of' the peripheries thereof being projected through `compl'emental slots formed in the front wall of! the casing andv employed in a man.- ner well known in the art.

The feed roller I4 is formed to provide spaced annular rings I8, having therebetween a runway over which a belt I9 is trained. Both ends of the belt are anchored to hold the intermediate portion thereof in frictional engagement with the periphery of the roller in the runway between the rings I8, the latter, of course, preventing lateral displacement of the belt.

For the purpose of operating the belt I9, I employ a spacer bar 2l! which is similar in construction to that shown in my Patent No. 2,162,706, and is adapted to be operated in the same manner. The spacer bar, however, in the present invention, forms a part of the compound levers 2| and 22, these levers being hingedly connected, as indicated at 23. The inner end of the lever 2l is hingedly connected, as indicated at 24, to the casing 1, at the juncture of the rear and bottom walls of the casing. The terminal of the lever 22 is engaged with the floor of the casing at the front of the latter, while the rear terminal is engaged with one end of the belt I9. The opposite end of said belt is secured to one end of a coil spring 25, the opposite end of said spring being anchored, as indicated at 26, to the upper face of the lever 22, ata point remote from the terminals of the latter. By this arrangement pressure on the spacer bar 20 urges the inner or rear end of the lever 22 downwardly to drive the feed roller I4.' As soon as pressure is released' on the spacer bar 20, the latter is returned to an operative position through recoil of the spring 25.

In order that the extent of movement of the roller I4 may be adjusted, I employ suitable means, such for instance, as a cam 21. The cam is mounted to ride on the lever 22, under operation of a handle grip 28. There is interposed between the periphery of the cam 21 and lever 22,a sound dampener or deadener 29, to eliminate the noise'incident to impact of the lever with the cam upon return of the spacer bar to a normal operating position.

In using the invention, after the copy has been placed in the holder, it may be moved by rotation of the paper feed rings l1. The feed rings are, oi' course, rotated through action of the roller drive means, the latter in the present instance consisting of the belt I9 and its associated mechanism, including the spacer bar 20. By this construction the operator is not limited to any predetermined spaces Which must of necessity be employed. He can optionally select any space within the limits of operation of the machine.

It is, of course, to be understood that various changes may be made in the details of construction, proportion and arrangement of parts, within the scope of the claims hereto appended.

What is claimed is:

l. A copyholder comprising a casing equipped with an axle and a paper feed roller sleeved thereover, the latter being spaced from the axle and rotatable on the latter, and means mounted on the axle to prevent relative radial movement of the roller on the axle.

2. A copyholder comprising a casing equipped with an axle, the terminals of the latter being flattened, plates mounted on opposite Walls of said casing and provided with slots complementing the flattened portions of said axle, the terminals of the axle projected through said slots into engagement with the casing Walls, and a paper feed roller rotatably mounted on said axle.

3. A copyholder comprising paper feed mechanism movable about a xed axis, drive means for the mechanism, and manual operating means connected to the drive means and operable to effect movement of the latter, the drive means including a slip belt and compound levers for positively actuating the mechanism any degree, predetermined by the operator, Within the range of movement of the mechanism.

4. A copyholder comprising a copy feed roller, a hand operating slip belt trained over the roller, and means in operative connection with the belt to move the latter to a fixed predetermined degree for eiecting a corresponding degree of movement of the feed roller, said means including compound levers one of which levers is engaged with said belt and the other anchored beneath the roller.

5. A copyholder comprising a paper feed roller rotatable about a fixed axis, and drive means for the roller` operable to move the roller to any predetermined xed degree Within the limits of movement of the roller operating mechanism, said means including coacting levers and a slip belt, an intermediate part of the latter engaging the roller, one end of the belt being engaged With one of said levers.

6. A copyholder comprising a copy feed roller, a manually operable drive belt trained over the roller, means in operative connection with the belt to move the latter longitudinally around the periphery of the roller to effect movement of the latter, said means including levers engaged with the belt.
