Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed December 19, 1914. Serial No. 878,015.

To all whom it may concern:

Be it known that I, ENGLAND J. BARKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Type-Writer Attachments, of which the following is a full, clear, and exact description.

My invention relates to attachments for supplying paper from a continuous roll of paper to the platen of a typewriting ma chine.

One of the objects of my invention is to supply the paper from several continuous rolls in such manner that it will not twist or buckle, but will always feed to the platen at right angles to the axis thereof.

Another object is to supply this paper from rolls journaled below the top of the table which supports the typewriting machine, out of the way of the typist, and so as to protect the hanging slack of the paper from being soiled. Yet another object is to improve the means for guiding the paper after it leaves the platen. And yet another object is to separate the paper just before it is fed to the platen of the typewriter to enable the operator to grasp and adjust the web of each sheet of paper so as to make the printed matter on each sheet register with the printed matter on the others.

These and other important objects relating to the simplification of the construction of said attachment I accomplish by the means hereinafter fully described, and as, particularly pointed out in the claims.

vation of a table and a typewriting machine embodying my invention, showing a part of the structure below the top of the table broken away. Fig. 2 is a plan view of my invention showing it applied to the broken away rear parts of said machine and said table. Fig. 3 is a rear view of the paper feeding rollers, a fragment of the top of the table, the uppermost paper roll and the.

broken away upper portion of the depending supporting frame-work of my invention, drawn to a larger scale. Fig. 4 is a vertical section taken on dotted line 4-4, Fig. 2, drawn to a larger scale. .Figs. 5 and 6 are detail views showing, respectively, a

side elevation and a transverse vertical section of the 'standardin which the feed-roll ers are journaled. Fig. 7. is a longitudinal section of one end of the roller upon which the roll of paper is mounted. Figs. 8, 9, 10 and Y11 are detail views showing, respectively, the front, the rear and a transverse section of the paper shield for the platen, and an edge view of a dog used in connection therewith.

Referring to the drawings, A represents the top of a table, which is supported by legs a and has, preferably, just in front of the transverse vertical plane of the rear legs, a comparatively long transversely elongated opening B, and just to the rear of opening B and said rear edge a shorter transversely elongated opening b. A typewriting machine C is mounted on the top of said table in front of and so that its platen will be parallel with the direction of length of said opening B, which latter corresponds to and is coterminous with the extent of the reciprocable throw of said platen.

Depending down from the top of the table immediately to the rear of the rear legs a thereof and down from the underside of said top between the two openings B, 6, thereof, are hanging frames 0, 0. These frames 0 consist, preferably of angle irons that extend nearly tothe floor, and are provided with corresponding equi-distant rearwardly extending brackets d, which, near their rear ends, have bearings for the rollers on which the rolls of paper which it is desired to feed to the platen of the type- In the drawings: Figure 1 is a side ele-- writing machine are mounted. These rollers comprise a hollow metal cylinder D, the ends of which are closed by the depressed central portion of a metal head E, the diameter of which latter is such that the marginal portions form end-flanges for the cylinder D. These heads E are provided with axially extending journals consisting of a spindle e, the inner end of which is headed to prevent its withdrawal, and the outer portion of which next said head is surrounded by a sleeve 6''. When the spindles of these rollers D are mounted in bearings in the rear ends of brackets d of the hanging frame 0, another sleeve F, whose outerend is flanged, is pushed over the outer end of spindle 6 until it bears against the under surface of the arm d, and thus confines the journals of said rollers in their bearings.

Secured to and arising from the top of the table back of opening B, at a point slightly to the side of the ends of openings b, are standards G, G. An upper and a lower feed roller 2 and 3 are adjustably secured upon horizontal shafts 4 and 5 that have bearings in standards G, G. The bearings for the up per shaft 4 are stationary, whereas the bearings for the lower shaft 5 are in journalblocks 6 that are vertically movable in vertically elongated chambers in the lower portion of standards G, and are kept at the limit of their upward movement by coilsprings 7 that are retained in position and adjusted by screws 8 tapped up through the bottom of said standards. The diameters of the portion of shaft 5 within the journalblocks 6 are, preferably, reduced in diameter, and the openings in standards G through which these reduced portions of the shaft extends are elongated vertically to permit of a limited vertical movement of said shaft and the feed roller 3 mounted thereon. The continuous strips of paper from the rolls on rollers D extend up through openings 7) in the top of the table, then between feedrollers 2 and 3 and then down through opening B. In order to separate said feed-rollers to facilitate the insertion and passage of said paper between the same, particularly when the paper is first threaded through the machine preparatory to utilizing my improved attachment, it is desirable to separate the lower from the upper feed-roller.

This I do by means of somewhat crescent shaped cams 9 the lower outer edges of which engage the portion of shaft 5 next standards G. These cams are fulcrumed to the inner surface of standards G mediate their ends and their upper branches are curved rearwardly and are adapted to be engaged by fingers 10 secured to and project ing forward from a rock-shaft 11, which latter is journaled in standards G at points in the rear of shafts 4: and 5, and in a horizontal plane between them. One end of said rock-shaft extends through its bearings and is provided with a knob or mill-disk with which to turn the same. When shaft 11 is turned so that the fingers 1O bear down on the upper extension of cams 9, the lower branches of said cams bear upon shaft 5 and push it and the feed-roller? downward away from roller 2 so that the paper can be easily threaded between the same. I prefer to make feed-roller 3 longer than feed roller 2 and to mill the central portion of both of said rollers.

The paper strips that pass down through opening B extend nearly to the bottom of a basket made of wire or other suitable material. The upper edges of this basket are secured in any suitable manner to the underside of the top of the table, and the basket extends down nearly to the floor, and the hanging slack paper that enters it is protected from injury and from being soiled. The paper then extends up out of said opening B again to and over a series of guiderollers 18. These guide-rollers are horizontal and are journaled at equal distances apart in the upwardly extending rearwardly inclined brackets 14 that separate the several strips of paper before they are fed to the platen of the typewriting machine. These paper strips, thus separated, extend horizontally forward fromrollers 13 'over a vertically arranged series of guide-rollers 15 that are journaled in uprights 16, which latter are connected by a suitable horizontal plate 17, and together therewith form the end-frames of a longitudinally reciprocable guide-truck for the paper, which is adapted to travel from side to side von a horizontal shaft 18, simultaneously with the carriage of the typewriter in which the platen is journaled. Shaft 18 is journaled in bearings in the upper ends of vertical posts 19 the base plates of which are secured to the top of the table at points intersected by the transverse vertical plane in the rear of the frame of the typewriting machine, and at suitable distances on either side of the same beyond the ends of elongated opening B. This shaft 18 is in a horizontal plane slightly above the axis of the platen, and the end-frames of the traveling truck, just referred to, have shoes 20 secured thereto, the undersides of which are provided with grooves into which shaft 18 enters.

Shaft 18 derives its motion from the platen, one of the journals 21 of which latter extends beyond its hearings in the transversely reciprocable carriage (not shown) of the typewriting machine and has a sprocket 22 on its end that is connected to a similar sprocket 23 on shaft 18 by means of a chain 24. Shaft 18 is provided with a suitable longitudinal groove 25, and sprocket 23 is provided with a suitable bolt 24 that is tapped through its boss into said groove 25 to permit said sprocket to move longitudinally on shaft 18 simultaneously with the carriage of the typewriting machine, but to move on the axis thereof or rotate therewith. The end of shaft 18, opposite that nearest which sprocket 23 is mounted, extends through its bearing and is provided with a sprocket 26 which, through the medium of a. chain 27, imparts motion to a sprocket 28 on the end of the feed roller shaft 4 and r0- tates the upper feed roller in such direction as to draw the record strips from the paper supply rollers at such speed as to always maintain the slack hanging portion of the paper between feed rollers 2 and 3 and the guide rollers 13.

From the guide rollers 15 the paper strips extend down under the platen 30, and after said strips leave the platen the paper passes up over a shield 29. This shield is provided at its ends with rearwardly extending lugs 31 in which the ends of a transverse rockshaft 32 are journaled. The shield is bent rearwardly over the platen, and in order to keep the paper against the same I employ a comparatively narrow plate 33 the ends of which are provided with upwardly projecting wings which are placed in front of said shaft 32. Just beyond the end of the shield 29, preferably, next lugs 31, shaft 32 is provided with dogs 36 that project'upward and forward and have their upper ends hooked and normally engaging the upper edges of the fingers 35, which latter project longitudinally from thewings of the plate 33. The incisions made in the ends of the dogs to form the hooks are such that when the dogs engage said fingers 35 they not only hold plate 33 down but space it apart from the shield such a distance that the paper from the platen can pass between the same. Shaft 32 is provided with a coil torsion spring 37 about midway its length one end of which latter is secured in said shaft and the other end bearsagainst the back of the shield, as shown.

In order to prevent the sagged or slack portion of the paper below the top, from being soiled by the operators feet or in any other manner, I have provided a basket 40, the frame of which is, preferably, made of metal strips 41? and the sides of which are, preferably, made of woven wire. The open top of this basket is secured under thetop of the table immediately in front of the pendent frame in which the supply rollers are journaled in such position that the paper from the feed-rollers will sag down into it, and then pass upward through opening B to the guide-rollers 13. This basket may be dispensed with, but I much prefer its use.
