To all 21:]; cm it may concern:

. Be it known that I, DANIEL V. SHIEK, a citizen of the United States of America, re siding at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Paper-Feed Devices for Conmuting-Machines and the like, of which the following is a description.

My improvement belongs to the general class of devices for regularly feeding the paper forward at suitable intervals during the printing operation.

It has for its particular object the production of a practical and cfiicient device for the purpose described, by means of which the feeding operation may be regulated with precision to any degree between the'limits of the device, and with greater exactness than is possible. by any of the devices heretofore used for that purpose.

T this end it consists of the novel construction, arrangement and combination of parts hcrcin shown and described and more particularly pointed out in the claims.

in the drawings. wherein like reference characters indicate like or corresponding parts. Figure 1 is a partial side elevation of a l'nachine equipped with my improvement; Fig. 2 is a top plan of the same; Fig. 3 is a longitudinal section of the machine, taken on line 3--3 of Fig. 2; Fig. l is a similar section taken on line 'l---t of Fig. 2; Fig. is a view of the platen. feeding rollers, and connecting parts, with parts broken away to show the construction: Fig. (3 is a section taken on line -4) of Fig. 5; Fig. 7 is a partial view of one end of the platen with parts broken away to show the construction; Fig. 8 is a sectional view taken through the friction driving roller. taken on line s---s of Fig. "3; Fig. i) is a section of the same, taken on line $l--.l of Fig. H; and Fig. it) is a sectional view showing a slightly modified form of gravity locking means.

My invention. which is designed to be used with slight modifications upon various forms of computing devices, is illustrated as applied to a con'iputing machine for which I have heretofore tiled application for Letterslatent of the l nited States. on December it), 1901. Serial Number 83.383. in this term of device, 1 is an oscillating type carrying bar carrying at its free end a series of longitudinally movable type which are suitably pcsitioned before the platen by the op eration of individual keys and the actuating dev ce of the machine. said type being driven against the platen and the interposed paper by means of suitable. spring-actuated hammcrs 3 controlled by rotation of the cam -l.

5 is the actuating rock-shaft operated by the lever (5. As shown. the rock-shaft 5 is provided with a crank-arm T connecting with a link 8, which has its opposite end connected with a suitable pinion or equivalent part 9 secured to a shaft 10. The shaft 10 is provided with a cam 11 for a purpose which will be hereafter described. (See Figs. 1 t0 4.)

12 is a bell-crank lever pivotally support ed at 13 and having one arm a extended in line with a cam 14, or equivalent part and the other arm 0 extended in line with the '"am 11, before referred to. connected to a longitudinally reciprocating bar or rod 15 carrying at its upper end friction rollers 16 adapted to coact with the platen 17 for the purpose of rotating the latter. v The lower end of the arm 15 is preferably provided with an anti-friction wheel 18, which rotates upon the cam 11. A spring 19 or equivalent means, tends to normally hold the roller 16 firmly in contact with the platen (see Figs. 2 and 4). The arm Z) which I have heretofore desi nated as one arm of the bell-cranl lever, becomes such bv reason of the fact that it is fixed to the shaft 13. while the arm-(z is also fixed to said shaft, the section of shaft between the two thus forming a part of the bell-crank (see Fi 2). The arm I). reciprocating bar 15, and friction roller 16, are preferably duplicated upon the opposite side of the machine, as may also be the cam 11, and such is the preferable construction for the purpose of securing regularity and accuracy in feeding the paper.

The cam it is mounted upon a rotatable shaft or equivalent construction 3!), which extends through the outer casing of the machine, as shown in Fig. 1, and is provided on'the -exterior with a pointer 20 cooperating with a graduated scale 21. A knob 22 may be positioned upon the pointer for convenience in operating the same. Suitable means may be employed for retaining the pointer in its adjusted position. In the cutln-dimeut illustrated the friction of the shaft 39 is relied upon to accomplish this result.

The latter arm is I Any suitable means may be employed to permit the rotation'of the platen and the friction rollers, each in one direction only,

to secure the proper rotation ofthe platen in the direction indicated by the arrows inv Fig. t. For thispurpose, the rotation of said parts is limited to one direction each,

so that upon the upward movement of the bar 15 with the friction rollers 16, said rollers shall be firmly held against rotation and by the friction ofthe same upon the platen,

will rotate the platen as indicated. On the' tutingthe part 24 a cam. Between the part 23 and the extension 24:, and located in the cam-space 26, ispositioned' a gravitylocking device 27, It will be readily understood that the platen mayfreely rotate in the direction indicated by the arrow, during which time the gravity locking device 27 will, by such action, be carried forward toward the larger portion of the space'26 without in any way interfering with such rotation. Any tendency of the platento rotate in the reverse direction however will cause the gravity locking device 2? to become wedged between the part 28 on the platen and the fixed part 24, and thus effectually lock the platen against rotation in that direction. The. friction-rollers 16 are preferably constructed in the same manner, the direction of rotation, however, being reversed for the purpose before stated. Thus each friction roller (see Figs. 8 and 9) is provided with the'fixed part 28 and the gravity locking de- V168 29, and the operation-being as before described. As shown in Figs. 6 and 7 the gravity locking device consists simply of a short section of cylindrical shape, which, by

reason of the form of parts, and the dimensions of the space 26, is suitably retained in position therein for effective operation. In Figl0, the gravity locking device'30 consists of a ball, the' doperation being the same. The platen and the rollers 16 are preferfbl covered with rubber or equivalent-material to increase the frictional contact.

31 and 32 are rollers mounted on the carriage and sufliciently contactingto carry a sheet of paper, between them in feeding the same forward until it reaches the point where it is grasped by the contact with the roller 16 of the platen and-to retain the paperin proper relative'position as the carriage is moved longitudin:\lly. One of said rollers is provided with a knob 33 extending from the end of the carriage by means of which their operation may be controlled. 34 is a sheet of suitable material for guiding. paper between said rollers, and onward 'to the point between the platen'and the friction rollers. The carriage is longitudinally i movable across the machinein a well known manner. and may he thus adjusted as desired. hen the friction-rollers 16 are in contact with the platen, it is the friction sutlicient to hold the latter in its adjusted position during the operation of the device. As shown, the carriage carrying the platen is mounted upon connecting bars 35, 35, one of which, as, for example, the, lower one shown in Fig. 51, rests in a grooved roller 36, while the upper one may be retained in suitable guides 37. The paper- rolls 31 and 32 are mounted in the frame of the carriage as stated and are thus movable longitudinallywith the platen. Abar 38 (Fig. serves to connect the bearings of the roller 16, so that by pressing upon said bar the tendency of the springs 19 (see Figs. 2 and 4) will be overcome and the friction rollers thus separated from the platen. Upon releasing the bar from the restraint of the hand of the operator, the friction rollers normally contact with the platen. I

' The mode of operation'is as follows: A sheet of paper is passed along the guide 31 .until it reaches'the rollers 31 and 32 where it is adjusted. By turning the knob 33, the paper is fed between the rollers and up to a 100 point between the friction rollers 16 andthe pla n. the friction rollers being; held backward by means of the cross-bar 38,-during such operation when the paper is suitably adjusted, as desired, the friction rollers are released, and the paper is firmly held between them and the platen. T he pointer 20 is moved along the graduated .scale to the pointdesired, depending upon the space desired between the rows of figures or equiva- 1 lent characters. By this action, the cam 11 is operated, permitting the arm a a greater or less limit of rotary or swinging movement, as desired. If, for example, considerable space is desired between the characters 5 printed, the cam 'will be turned in the di rection indicated by the arrow (Fig. 4) to such point as desired to secure the spacing required. it being understood that the vertical movement of the bar 15 is limited by the position of the cam 14:, by reason of thebell-crank construction 'before described. After the controlling keys (not shown) are set as desired, the operating lever 6' is actuated, operating the bars. carrying type, andv releasing the coeperating"hammers. Dur ing this operation the cam 11 has been rotated, permitting the bar 15 to move dowm ward its limit of movement the rollers 16 following the surface of the platen as a base and constantly holding the paper in position on the platen. After the printing operation is completed, and as the parts are returning to their normal positions, the higher portion of the cam 11 comes in contact with the roller 18 carried by the bar 15, moving the latter and the friction rolls upward and rotating the platen 17, in the direction indicated by the arrow, the desired distance. When it is desired to shift the carriage longitudinally the operator depresses the bar 38 thus separating the rollers 16 from contact with the paper and platen, when the latter is free and may be moved as desired. The paper will-be maintained in proper relative position by means of the rollers Ell-32.

It is obvious immaterial modifications may be made without departing from the spirit of my invention, hence I do not wish desire to secure mountedupon the frame of the machine and transversely movable relativeto the other part to advance the paper, and reciprocating means for operating said paper feeding mechanism.
