Specification of Letters Patent. Application filed April 15, 1912. Serial No. 690,941.

Patented Oct. 14, 1913.

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 Im-' provements in Type-Writer Attachments, of which the following is a full, clear, and exact description.

My invention relates more particularly to attachments for typewriting machines through the medium of which a continuous web of paper may be fed from a rollto the platen to receive the impressions from the printing mechanism of the typewriting machine.

One of the objects of'my invention is to construct said attachments in such manner that a plurality of rolls of paper may be supported independently of the typewriter and moved simultaneously with the carriage thereof so that the paper can always be fed thereto at ri ht-angles to the platen.

Another 6 ject of my invention is to arrange statiOnary means supported independently of the machine to enable the paper from the continuous web to be torn off in such lengths as may be determined by the operator.

Still another object is to arrange for manifolding ribbon-rollers with fixed axes that are supported independently of but actuated by the carriage at the end of its throws.

These objects I accomplish by the means and in the manner hereinafter fully described, and as more particularly pointed out in the claims, reference being bad to the accompanying drawings forming a part hereof, in which- 1 Figure 1 is avertical side elevation of 'a typewriter, of a well-known type, showing my improvement applied thereto and in op erative relation therewith. Fig. 2 is a vertical front elevation of my invention detached from the typewriter. Fig. 3 is a top plan view of the connecting bar used in connec-v tion with my invention. Fig.4 is a horizontal sectional view taken on line 44, Fig. 2. Fig. 5is a'detailed view of'a frag mentaryportion of the device showing the actuating mechanism for the manifolding material. Fig. 6' is a diagra'n'imatic-al'view of a transverse portion of the typewriter platen, the cutter-blade and the feed-plate Finger 15 supports the spindle for a suitfor the paper web. Fig. 7 is an enlarged are of the usual well-known form so that the details thereof need not be elaborated herein. This typewriter is mounted on a suitable base, 1, in any manner, and back of the typewriter a substantially U-shaped frame 2, is secured in such manner that the parallel arms of the same form vertically disposed standards that arise to a point above the top of the typewriter, and have their upper ends connected by means of a horizontally disposed rod or track 3. Mounted upon this track 3, and movable thereon by means of concave rollers 4., 4:, is a suitable frame or rack 5, that is, preferably, rectangular in shape and has itsupper horizontal members connected to said rollers by means of hangers 6, 6, in the up;

per ends of which the rollers are journaled. Secured to one of the vertical members of this rack-frame (preferably, the left-hand member) are a plurality of stationary bearing-bosses 7, 7, on which are mounted a cor-'- responding number of rolls of paper 8. 8.

The opposite ends of these rolls of paper have bearings 9, 9, that are supported by the opposite vertical members of said rack thatconsist of suitable substantially L- shaped plates whose lower ends are pivoted by means of a pin 10, to the adjacent vertical member ofthe rack and are kept normally pressed toward said rolls of paper by means of suitable springs 11. Each plate is provided with a handle 12 by means of which the respective bearings may be moved toward or away from its respective roll of paper.

At a point slightly below the horizontal plane of the lowermost paper roll bearing, the vertical members of the U-shaped frame are provided with forwardly projecting arms 13, the forward ends 14, of which are, preferably, bent or deflected horizontally at substantially right angles to themselves away from the typewriting machine, and are provided with a downward projecting finger 15, and a similar shorter finger 16.

scription of one will suffice.

able manifolding ribbon-spool 17 mounted in a vertical plane, and finger 16, carries on its lower end a suitable guide-roller 18, over which the ribbon passes from one side of the machine to the other where it is wound upon the opposite spool. As these spools and their actuating mechanisms are the same on each end of the attachment, the de- A suitable ratchet 19, is secured to the spool 17, and is adapted to be engaged and actuated by a suitable pawl 20, pivotally mounted on a lever 21, of the second class, and one end of the latter is fulcrumed on said spindle and the other end thereof has a trip, 22, pivoted thereto. This trip consists of a short strip of metal, preferably, about the width of the lever 21, and its unsecured end projects beyond the extremity of said lever. Pawl 20, and trip 22, are maintained'in normal position by means of a spring 23.

When the carriage is approaching the limit of its movement in one direction durinig; the writing operation (from right to le one of the pawls 20 say at the left of the machine is disengaged from its ratchet wheel. As, the carriage continues'to move to the left, trip 22 at the opposite right hand end of the machine will meet the upturned end 24 of an arm 25 (one of which is mounted on each end of the carriage) and will move its leverand ribbon-spool to wind a portion of the ribbon. When, however, the carriage is moved to the ri ht to return it to a new writing position, this trip 22 will, owing to its engagement with stoppin 26, pass over the upturned end 24 of the arm and be moved independently of its respective ribbon-spool and lever and will not actuate the latter.

When the ribbon is to be reversed or moved in opposite direction, pawl 20 of one ribbon-spool is disengaged from the ratchet by swinging it away from the same far enough to permit the spring to press against it on the opposite face, while the pawl on the opposite 'or winding ribbon-spool is moved into engagement with its respective ratchet and the operation proceeds as above described.

The manifolding ribbon is adapted to pass across the platen C, substantially in'alinement with the ribbon of the typewriting machine, and in order to make two manifold copies two ribbons, one placed upon the other, are wound on these spools.

The continuous webs of paper from rolls 8 are fed across the paper-guide plate D, belowa retaining plate 27, and thence around the platen where they are threaded between the triplicate ribbon and out from the 13,- of the frame is platen. Connecting the outer ends of arms a transversebar 31, preferably, of angle-iron that has its rear edge beveled to form a cutting-edge m below which the webs of paper extend after assin around the platen of the mac ine. W en the typewriting has been completed, the webs of paper are drawn from the carriage of the typewriting machine and torn off or sheared along this cutting-edge.

The rack-frame for the paper rolls 1s adapted to be moved with the carriage of the typewriter, and in. order to do this, a suitable horizontally disposed'bar 29 is secured to the lower horizontal member of said rack-frame. This bar 29 has its forward end bifurcated, as shown, and the two arms 30 thereof engage the adjacent portion of the oarria e B, of the typewriting machine, and said ar is so constructed that it may be readily detached from the carriage in order to disengage the paper rackframe from the typewriting machine. order to provide sufiicient flexibility to the connection between the typewriter carriage and paper-roll rack to prevent jarring when the carriage is moved suddenly, I prefer to connect the lower ends of the vertical members of frame 5 by a pair of flexible parallel metallic cross-bars 5 About midway the length of these cross-bars, a suitable block 5 is secured between the same to which the rear end of bar 29 is rigidly attached, so that the jar will be taken up by the transverse bending of these bars and thus form a flexible connection between the same.

While I have described and illustrated a specific form of my invention, it of course will be understood that numerous modifications and changes may be made to the samev without materially departing from the spirit of m invention, for it is obvious that the attac ment may be applied to typewriters of various constructions with but sli'ght alterations of the parts. All such modifications and changes, I desire it to be understood are included as part of my invention, as set forth in the following claims.
