PAPER-CARRIAGE FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 432,297, dated July 15, 1890.

Application filed July 5, 1889.

construction of parts comprising the papercarriage, to economize in the cost of its construction, and of repairs to or replacement of any of its parts, and to make the same more efficient and effect greater rapidity of writing.

My invention accordingly consists of the combinations, constructions, and arrangements of parts, as hereinafter more particularly described in the specification, and

pointed out in the claims, reference being had to the accompanying drawings, wherein Figure 1- represents an elevation, partly sectional, .of a type-writing machine paperholding carriage embodying my improvements. Fig. 2 represents an end view, partly in section, of same, looking in the direction of arrow 1, Fig. 1. Fig. 3 is a like view of said end, showing part of pawl-and-ratchet mechanism on the shaft of the upper roller at said end removed, and also showing pressure-fingers for said roller. Fig. 4 is an end view, partly in section, of the opposite end of the carriage. Fig. 5 is a plan of part of the base-plate of the carriage, showing adj ustable stop-finger for limiting the return movement of the carriage; and Fig. 6 is an elevation of the base-plate of the carriage and the machine-bed, the latter being in dotted lines, with roller-supports on said machine-bed for the carriage.

A represents the paper-carriage, consisting of a bottom plate or based and end bearings, standards, or supports B and C for the paperearrying rollers D and E. The bottom plate a has preferably dovetail or other like edges a supported and sliding in a correspondingly-formed guideway a in the frame A of Serial No. 316,589. (No model.)

the machine. The guideway a is open from end to end of the machine transversely, and

the carriage is considerably longer than the machine A is wide, as shown-more plainly in Fig. l, and has suitably formed and arranged feeding-racks (L3 on the under side of the bottom plate, as illustrated, or otherwise,'as desired. The paper-carriage is normally not in engagement with its actuating feeding-pawls or mechanism, or is normally independent of the same, and is only in engagement therewith when a key or finger-lever is depressed, as fully set forth in anotherpending application of an even date herewith, Serial No. 316,591, and therefore said feeding mechanism is not shown in the drawings, as it forms no part of my present invention, as any desired form of feeding mechanism maybe used in connection with the independent carriage A. The latter being normally disconnected from its feeding-pawls, it is normally free to slide or can be adjusted longitudinally in either direction, as desired, to suit the work to be done without necessitatingmanual disengagement of its feeding mechanism, and as it slides in an open end guideway (t the carriage can be at once removed from the machine and another of different length substituted for printing on extended widths of paper, and this avoids the necessity of making specially-large machines for large or extended lengths of paper-carriages.

To give additional support for extended lengths of carriages, fixed side arms or brackets a a on the machinebed A, having suitable guideways or supports for the carriage, may be used, as shown in Fig. 1, or hinged or pivoted arms or brackets a", with end supporting-rollers a, may be employed, as shown in Fig. 6. The advantage of using the hinged or pivoted brackets a is that when long car'- riages are not used and when the machine is packed for transportation or other purposes the brackets a can be swung around to the side of the machine to reduce its transverse width, as indicated to the right of Fig. 6.

The roller E maybe journaled or mounted in the carriage-standards l3 and C, as desired. The upper roller D is mounted in standards B and C so as to be bodily separable throughout its entire length from the roller E to facilitate the insertion of the paper, especially when manifolding, between said rollers. To this end I make the standard 0 in sections, the upper sect-ion 0 being pivoted or hinged to the lower section, as indicated at c, and in this pivoted section is journaled the end (1 of shaft (1 of roller D. The opposite end (1 of said shaft (1' is journaled in an elongated slot 1), having an open upper end in standard B, said shaft end (Z being held to its bearing by a pawl l), suitably pivoted to the standard B, and having a spring b which acts to impart to pawl b a downward pressure upon the shaft end (1 By providing the pawlb with a suitable handle or lug b, by means of which it can be manually disengaged from shaft end (Z the roller D can be raised or swunon the pivotal connection of section 0 of standard G to separate it from roller E, as indicated by dotted lines a, Fig. 1, for ready insertion of the paper between the rollers D and E, which is especially advantageous when manifolding a number of sheets or copies, as the latter can be instantly inserted between the rollers without liability of slipping upon each other.

Upon the end (I of shaft (Z,at its outer end, is a knob or handle f for manually turning the roller D in either direction, as desired. Back of said knob or handle is a ratchetwheel f, having a check-spring pawl f secured to standard-section c and an actuating-pawl g, pivoted at g to a lever G, loosely mounted on shaft end (Z. Said pawl g is pro vided with a handle or lug g for manually engaging said pawl with the ratchet-wheel f for rotating the roller D to turn the same in order to feed the paper for the lines of printing or writing. Said pawl g is so pivoted that it is normally out of engagement with the ratchet-wheel f, as more plainly indicated in Fig. 2, so that it will not interfere with the rotation of the roller 1) when a movement of knob or handlef is made.

The lever G has at its upper end a screw 9 the end of which abuts against the standard -section extension 0 being maintaiued normally in such impingement by a spring acting against a toe g at the lower end of said lever. (See more plainly Fig. 3.) The screw limits the movement or adjustment of lever G in one direction, and its toe g limits the movement of said lever in the opposite direction. By adjusting the screw g the extent of movement of the lever G is varied to correspondingly vary the extent of movement of the pawl g and the ratchetwheel f to increase or decrease the turning movement of roller D and in turn the feed of the paper for the distance between the lines.

To rotate the roller-D by the pawl g, the operator presses against its knob or handle 9 the first movement of which engages the pawl g with the ratchet-wheelf', after which the lever G and pawl 9 move together to rotate the ratchet-wheel and in turn the roller D, the

terminal movement of said parts being limited by the lever-toe g abutting against a shoulder or ledge on standard-section c. As soon as the pressure is released from the pawl g the reaction of spring returns the lever G and pawl g to their normal positions. WVhen in this position, the pawl g is free from the ratchet-wheelf, and by then turning the knob or handle f on shaft d the roller D can be rotated in either direction to any extent, as desired, independent of its feeding move ment for spacing between the lines, such independent rotation being especially desirable for underscoring, canceling, and other like purposes, as fully set forth and claimed in my other aforesaid pending application of even date herewith, Serial No. 316,591. It will be noted that as the rotary-feeding mechanism for the roller D is located or mounted on its shaft and standardsection c all of said parts move with the roller when it is raised or separated from the roller E.

It is obvious that the novel features of construction of the separable roller D, as well as those of the rotary-feeding mechanism, are applicable to different forms of paper-holding carriages having presser-rollers.

If it is desired to limit the return slidingmovement of the carriage, this may be done by using an adjustable stop II, sliding in openings in standard or standards B and G and held in its adjusted position by a set-screw h, the end of said rod being bent, as indicated at h, and adjusted to strike against the end. of the way or guide a", as indicated in Fig. 5, to stop the return movement of the carriage; but, if desired, any other suitable stopping device may be employed, as I do not in this application claim such stopping mechanism.

\Vhat I claim is 1. In a type-writer paper-carriage, the combination of the fixed bracket B, having at its top an open end bearing, the sectionalbracket 0, having lower fixed part and upper swinging part, the lower roller E, journaled in the fixed bracket B and in the fixed part of the sectional bracket 0, roller D, having one end journaled in the swinging part of bracket 0 and its other end in the open bearing of bracket B, and retaining device for the jour-- nal of roller D on said open bearing, substantially as set forth.

2. In a typewriter paper-carriage, the standard B, having an open end slotted bearing, a movable pawl in said slotted bearing, the sectional standard (3, and roller D, having one end journaled in said sectional standard 0 and the other in said slotted bearing, substantially as set forth.

3. In a paper-holding carriage, the combi nation of slotted bracket B, movable pawl in said slotted bracket, standard C, having hinged or pivoted section 0, and roller D, substantially as set forth.

4:. In a paper-holding carriage, the combi nation of .a hinged or pivoted bracket, a fixed bracket having an open bearing, a roller- ICC TIO

platen D, having one end journaled in the hinged bracket and the other journaled in the open bearing of the fixed bracket, and a retaining device in said fixed bracket for the end of the roller journaled in said open bearing, substantially as described.

5. In a type-Writer paper-carriage, the combination, with roller D and its shaft (1, of a ratchet wheel rigidly secured to said shaft, a lever journaled concentrically on said shaft and having at one end a toe g and at the other end a set-screw 9 a feeding-pawl for said ratchet pivoted in said leverand normally out of engagement with the ratchet, and standard C, having stops for said setscrew and toe for regulating the extent of said lever and paw], substantially as described.

G. In a type-writer paper-carriage, the com- 20 bination, with roller D and its shaft (1, of a standard 0, having stops for said set-screw and toe for regulating the step-by-step feed of said lever, and frame for roller D, and a feed-knob f, rigidly secured to the shaft of roller D for turning said roller independently of said step-by-step feed mechanism, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

GEORGE C. BLIOKENSDERFER.
