1'0 all whom it may concern:

Be it known that I, ENGLAND J. BARKER, a citizen of the United States, and a resident of Morgan Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is afull, clear, and exact description.

My invention relates more particularly to the aper-feeding devices of a type-Writing machine; and its object is to enable the paper to be fed to the printing mechanism thereof from a continuous paper-roll mounted on a suitable reel, which is carried by and moves with the carrier of the machine; and a further object of the invention is to supply the paper for the manifolding of matter printed by the machine in the same manner and to accomplish the registering and alining of both the original and manifolded copies, as well as supplying the carbon-ribbon for manifolding from the mechanism also carried by the carrier of the machine and automatica ly actuating the said manifold carbon devices at the end of each reciprocation of the said carrier. This I accomplish by the means hereinafter fully described and as particularly pointed-out in the claims.

In the drawings,,Figure 1 is a plan view of a well-known and extensively-used typewriting machine with most of the printing mechanism thereof omitted and with my improvements applied thereto. Fig. 2 is a side elevation of the same. Fi 3 is a rear elevation of the reel-supporting frame of my invention removed from the type-writing machine.

Fig. 4 is a detail view of one of the manifolding carbon-ribbon spools and conjunctive devices broken away from the'machine. Fig. 5 is a detail view of said spool looking at it from underneath. Fig. 6 is a pers ective View of a part of the cooperating mec anism of the spool located at the end of the machine opposite the spool illustrated in Figs. 4 and 5. Figs. 7 and 8 are diagrammatical views showing the manner of threading the paper through the machine.

My invention may be used in connection with any type-writing machine and may either be incorporated as a part of a new machine or applied to an old one. The adoption or application of my improvements does not require any change of the supportingframework A of the machine nor of the printand-G.

ing devices X thereof, but is attached to and reci rocates with the carrier B of the said mac he The carrier of most type-writing machines,

and particularly that of the machine to which in the drawings my invention is shown to be ap lied, com rises a rectangular supportingrame and as an im ression-cylinder C j ournaled in the end bars t iereof, around which the paper is passed as it is written u on. This cylinder is provided with suita le stripping or guide plates a and roller 1) for retaining the paper against and upon the cylinder, althoug 1 it will be understood that either or both said guide-plate and roller may be dispensed with without affecting the utility of my improvements. In addition to these features, however, in r invention comprises a cutting-blade d, w ich consists of a flat strip of metal of a length corresponding to that of the cylinder, which has pivotal lugs d d, that are pivoted to the upper corners of the upper straight edge thereof, and it is normall kept in position over the lower portion of tile guide-plate a (but separated therefrom sufficiently to permit the paper to pass between the two) by means of s rings LP. The machine is provided with t 1e usual inking devices for making the original imression,-Which in the type-writer illustrated in the drawin s consists of two horizontallydisposed spoo s c c, which are suitably journaled one on one side and the other on the other side of the center of width of the machine between the cylinder O and the front of the machine, and these spools roll up and unroll the inkin -ribbon E, which latter extends from said rcfilers toward the cylinder and contacts with the paper on the latter in a plane midway between the spools. In addition to this ribbon E, I. employ a ribbon F for making' the manifold impression. This ribbon F extends longitudinally in front of the cylinder in the same plane as ribbon E, where it enga es the same, and its ends preferably extend eyond the ends of the carrier-frame and are wound upon the horizontal spools G Spools G and G are journaled in suitable brackets made by extending the ends of a longitudinal bar which preferably extends from one end of t e carrier-frame to the other and is suitably fastened to the end rails thereof. These brackets g a suitable distance beyond the ends of the carrier are of the machine.

preferably bent vertically downward a suit-r able distance and then extend horizontally and havetheir ends g bent back under said' spring h, coi ed around the s indle above. the

spool, and a nut h, screwe onto the upper screw-threaded end of said spool, so as to 'complress said springs. as t One of these spools 0 carrier a proaches the limit ofits movementtowar the end of the machine adjacent to which said s 001 is located is given a slight movement sui cient to shift the manifold-ribbon slightly, so' as to present a fresh portion of the same to the act1on of the type I accomplish this intermittent movement of the said spool by means of a suitable ratchet j spindle it between the parallel portion of the crooked end which ratchet is engaged by a suitable pawl H. The pawl H at one end of the'machine is pivotally mounted upon a lever I of the second class, and one end of the latter is fulcrumed on the s indle and the other end thereof has a trip pivoted thereto. This trip J consists of a short strip of metal, preferably of the same width as the lever I, and its unsecured end projects beond the extremity of said lever and is preferabl beveled on one side. Pawl H and trip are maintained in the normal positions shown in Fig. 5 of the drawings by means of a spring H, and when the carrier is approaching the limit of its movement in the properdirection the straight edge of the trip J will meet the upturned end of an arm J (the oposite end of which is secured to the supportm -framework A of the machine) and moves in ependently on its pivot, so as to escape past said arm. When, however, said carrier starts to move in the opposite direction, said trip will engage said arm J and by means of its enga ement with a sto -pin x will not vield in ependently, but wi 1 cause the lever to move with it, so that the pawl will engage the ratchet and move the s indle and s ool thereon a short distance. Vhen it is esired to move the manifold-ribbon in the opposite direction, the pawl H is disengaged irom the ratchet by swinging it away from said ratchet, in which position the s ring engages the opposite face of the paw H, and the movement of the carrier in'the op osite directionis utilized to turn the spool 8, located at the op osite end of the machine.

' The spindle h o the s 001 G has its ratchet ;i en aged byfthe aw H' at a point diametrical y oppos te w ere the pawl H, used in connection with the spindle h, engages the which 1s secured to the ratchet j. This is necessary in order to re-' verse the direction of the intermittent movement of the manifold-ribbon. The awl H is pivotally mounted upon the lever of the first class, which latter is fulcrumed mediate its ends on the s indle h". the lever K o posite that to which the pawl H is pivoter it is provided with a trip k, which is constructed similar to trip J, hereinbefore referred to, and is ke t in a position in which it alines with lever and projects beyond the extremity of the same by a suitable spring k, substantially as shown in the drawings, When the earner ap roaches the limit v of its movement toward w ich the adjacent bracket extends, the end of the trip It engages the laterall -bent extremity of an arm m and moves the ever K on its fulcrum in such direction that the pawl H engages'the ratchet j and moves the spindle h and the spool G, mounted thereon, a slight distance. After the carriage commences to move in the opposite direction the trip is when it strikes against the arm m is free to move on its pivot independently of its lever K and escapes past said arm without affecting said lever.

I do not wish to be confined to the exact construction of the mechanism just described for giving the spindles G and G an intermittent movement, as it is obvious other mechanism might be employed for this purpose. The ribbonwolind on these spools ma extend directly therefrom to and longitudinally in front of the cylinder; but I prefer to provide the arms m, which are secured to the racket and project laterally therefrom and have their outer ends bent vertically to form guides, in front of which the ribbon passes and between which it is maintained in a straight course in front of the cylinder in the proper plane.

Secured to and projecting rearwardly, one from one end of the carrier and the other from the opposite end thereof, are two corresponding bars N, which have their rear ends connected to the upright 12. of an inverted-U- shaped reel-frame, whose lower ends are secured between the extremities of the longitudinal parallel members 0 of a suitable truck, which latter is en ported by grooved wheels 0, that are placed )etween-the said memberso and have their journals p extending laterall into horizontall -elongated bearing-slots in said side mem ers. These slots reduce the friction b permitting the axles of wheels 0 to carry t e weight of the frame and in so doing act in the same manner as ordinary rollerbearin s. These wheels travel on a single track ,which is supported by suitable brackets 88, secured to and projecting rearwardly from the lower portion of the supportingframe A of the machine and are of sufficient length to permit of the travel of the said truck and reel-frame supported thereby back and forth a distance corresponding to the recip- At the end of rocal movement of the carrier and simultaneously therewith. i

At a point preferably above the plane of the carrier I journal between the uprights n n a paper-roll Q, and in a suitable lane below the roll ,I journal another roll of paper q. These rol s of paper supply the machine with the aper to be Written upon, and as unwound t e paid-out portions extend from said rolls to and between the arallel guiderods r 1', whose ends are suita ly secured in standards s, secured to and arising from the horizontal bars N at points near where the latter are attached to the carrier of the machine.

If desired, guide-blocks t may be adjustably mounted on these rods 1' r to guide and prevent lateral movement of the pa er as it passes between them, and these b ocks are secured in their adjusted position by setscrews T. From therods r r thecontinuous strips of pa er extend to and under the impression-cy inder of the machine and then up around and in front of thesame in the usual manner. After receiving the type irn pression the paper passes up between the guide-plates a and cutting-blade hereinbefore referred to, and when it is desired to tear off the pa er after it has passed around the cylinder a 1 that the pperatorhas to do is to move the portion of the pa or upon the above said cutting-blade outwar as shown in Figs. and 7, and then tear it off by bringin it in sharp contact with the upper cutting e ge of said blade.

It is desired that the paper-rolls Q and g be journaled between the uprights n n of the truck-frame in such manner as to be easil removed and replaced. This I accomplish by means which are substantially the same for both the rolls, which consists of a centeringdisk 2, whose spindle 3 is journaled in the parallel portions of a U -shaped bearingirame 4, secured to one of the uprights n, and whose side 0 posite said bearings has a concentric circu ar boss 5 projecting therefrom, which enters the bore of the hollow core upon which the pa er is rolled. At the opposite end of the rol l I provide a centering-disk 6, which is the same as disk 2, but has its position reversed and has its spindle 7 journaled in parallel bearing-lugs 8, projecting from the contiguous end of a horizontally-disposed segment 9. This segment is made integral with a vertically-disposed arm 10, whose lower end is pivoted to the upright n. Arms 10 are ke t normally bearing toward the aper-rolls by means of springs 11, one en of which latter is wound upon a stud projecting from the upright it back of the outwardly-offset portion of said arms and the other end of which bears against a suitable stud projecting inwardly from the inner surface of the said ofi'set portion. The segment 9 is provided with a segmental slot 12, through which a set-screw 13 is tapped into the up thereof and have provide right. By properly mani ulating this screw the disk-bearings carried y the arm 10 can be secured, moved to, and maintained at the limit of its movement toward the paper-roll or in any position to which it ma be adjusted away from the same. In or er to facilitate the handling of this arm 10' and the bearings carried thereby, I have extended the outward end of the se mental portion 9 the same with a laterallyrojecting handle or finger-grasp 14.
