PAUL A. GALLIEN, SHATTUCK, OKLAHOM A.
T 0 all whom it may concern Be it known that I, PAUL A. GALLIEN, a citizen of the United States, residing at Shattuck, in the county of Ellis and State of Oklahoma, have invented certain new and useful Improvements in Paper-Feeding De vices, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to certain improvements in paper feeding devices and has rela-' tion more particularly to a device of this general character especially designed and adapted for use in connection with typewriters, including a rotary platen, and it is an object of the invention to provide a device of this general character having novel and improved means whereby thepaper is properly fed to the platen upon rotation of the platen.
Another object of the invention 1s to provide a novel and improved device of this general character embodying a body plate adapted to be mounted upon the carriage of a typewriter and provided with means for holding a paper pile thereon together with means operated from the platen of the typewriter for intermittently feeding to the platen a single sheet from the pile.
An additional object of the invention is to. provide a novel and improved device of this general character embodying a body plate adapted to be secured to the carriage of a typewriter in requisite relation to the platen of the carriage and which is adapted with a feed roller driven from the platen and operating to deliver a single sheetto the platen and wherein means are carried by the body plate for constantly urging a paper pile toward the feed roller and from which pile said roller delivers the single sheets.
Furthermore it is an object of the invention to provide a novel and improved device of this general character including a body plate and a feeding means carried thereby together with means carried by the body plate and coacting with the paper; pile arranged thereon for regulating the feed of the single sheets.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved paper feeding device whereby certain important advantages are attained and the device rendered simpler. less expensive and otherwise more convenient and advan- Specification of Letters Patent.

tageous for use, as will be hereinafter more fully set forth. y
The novel features of my invention will hereinafterbe definitely claimed.
In order that my invention may be the better understood I willnow proceed to describe the same with reference to the accompanying drawings, wherein;
Figure l is a view in front elevation of a paperfeeding device constructed in accordance with an embodiment of my invention, the coacting portion of the carriage of the typewriter being diagrammatically indicated by dotted lines, a shaft for the platen being partially in fiill lines to illustrate the driven connection between the feed roller of my improved device and the shaft of the platen,
Figure 2 is a view in top plan of the structure as illustrated in Figure 1, the major portion of the carriage of the typewriter being also diagrammatically illustrated by dotted lines,
Figure 3 is a vertical sectional view taken through the central portion of Figure 1, the adjacent portion of the typewriter carriage being indicated by dottedlines, and
Figure 4 is a fragmentary sectional view illustrating the means for holding my improved device in applied position, the coacting portions of the carriage being diagrammatically indicated by dotted lines.
As disclosed in the accompanying drawings, C denotes the carriage of a typewriter of any desired form and which carries the rotatable platen P, and which carriage includes a forward bar 1 connecting the end members of the frame of the carriage. The platen P includes. as is well known, a shaft 2 having one end portion extended and to which extended end portion is suitably fixed an operating member or head 3 whereby the platen P may be rotated by the operator as desired, although it is to be understood that the platen P is adapted to be rotated in a conventional manner, when desired. by the well known pawl and ratchet mechanism.
My improved feeding device includes a body plate B of desired dimensions and;
of, each of the flanges 1 is provided with recess or noteh to receive the bar 1 when my improved device is in applied position. and as herein embodied my device when ap- 5 plied has the body plate .13 at its lower or forward portion in contact with the paper shelf or table (3 indicated by dotted lines in Figure 2%. The body plate It at each end portion is also provided with an outstanding lug T and threaded through each of said lugs is a threaded shank or screw h which is adapted to engage the carriage frame to maintain my improved device in applied position. In the present embodii'nent of my invention. each of the shanks or screws 5 has contact with an end of a rear member 2) connecting the end members of the frame.
I. and with which the paper shelf or table I (i is engaged as is well known.
Rotatably supported by the flanges 1 adjacent their lower or forward ends is a shaft 10 and fixed to said shaft and substantially snugly fitting between the tlanges 1 is a feed roller '11 of rubber or its equivalent. and which roller upon rotation is adapted to engage the uppermost sheet of a paper pile A and deliver said sheet to the platen l The shaft 1() is provided with an extended portion to which is tixed a pulley 12 in driven eonneetion with a pulley 1 f fixed to the shaft said (onneetion being herein diselosed through the instrumentality ot' a cord belt 15.
16 denotes a follower plate having one end portion hingedly or pivotally connected. as at 17. with the central part of the upper or rear portion of the body plate B. The op posite or free end portion of the plate is continued by a downwardly curved extended portion apron 18 which overlies the rear portion of the roller 11 as is partimtlarly illustrated in Figure 3.
The paper pile A is superimposed upon the plate '16 with the forward or lower marginal portions of the sheets of said pile extending between the roller 11 and the extension or apron 18 of the plate '16 and at a desired distance thereheyond. and the plate It) is constantly urged outwardly to assure the desired frietional contact between the roller 11 and the uppermost sheet of the pile A so that as the roller 11 is rotated. said uppermost sheet will be properly delivered to the platen P. In the present embodiment of my invention. the plate 16 is constantly urged out 'ardly through the medium of spring arms 19. each of said arms being a continuation of a coil 20 substantially anchored to the body plate B.
The upper hingedly marginal portion of the follower plate 16 at its central part is provided with a relatively large recess "21 substantially V-shaped in form. with the apex portion of said recess forwardly or 5 downwardly directed.
The body plate within the tield detined by the reeess 31 is provided with an elongated slot 2; preferably per wndieular to the shaft 1H. and through this slot 22 direeted a shank 23. The inner end portion of the shank 23 is provided witha head 21 which engages the outer face of the body plate B. while threaded upon the lower or free end portion of the shank 23 is a elamping nut 5. herein diselosed as a winged type. and which nut engages the under surface of the body plate I") to clamp the shank 23 at a desired point lengthwise of the slot 222.
Extending outwardly.from the head 2-1 and coplanar therewith is a penetrating member or blade 26. the rear marginal PM" that of which is formed into a knife edge.
'hen the paper pile A is superimposed upon the follower plate 11'. the member or blade '30 is disposed through the rear marginal portions of the pile A at the eentral part thereof whereby the pile A is held in desired position upon the plate 1t' and particularly with respect to the platen P. liy moving the member or blade 2t downwardly or forwardly. the lower marginal portions of the sheets of the pile A will normally be in relatively close proximity to the platen 1 so that the sheets of the pile will be delivered to the platen P upon rotation of the roller 11 in relatively close sueeession. As the member or blade 213 is moved upwardly or rtairwardly. the iiitervals of delivery of the sheets of the pile to the platen l will he correspondingly lengthened.
In practice. as the platen P is rotated during a writing operation. the roller 11 will rotate in unison therewith resulting in an initial travel of the outermost sheet of the pile A toward the platen I and as the sheet disposed around the platen is discharged from writing position upon requisite rotation of the platen P, a second sheet will be delivered from the pile A to the platen and substantially in a desired position for a writing operation.
Bridging the space between the flanges 4 in advance of the roller 11 and supported by said flanges 4 is a guard plate 27. This guard plate 27 extends below the roller 11 and the lower marginal portion thereof. at the central partof the guard plate 27 is provided with a forwardly and downwardly inclined apron 28 which. as illustrated in Figure 3 of theaeeompanying drawings. is suh stant-ially sigmoidal in cross section. As the sheet passes upwardly and outwardly from the platen P, the guard plate 27 together with the apron E28 prevents said sheet from coming in contact with the roller 11.
From the foregoing description it is thought to be obvious that a paper feeding device constructed in accordance with my invention is part'ieularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also. be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement er, means for constantly urging said follower plate upwardly and toward the roller, and a penetrating member carried by the first named member and adapted to be disposed through a paper pile superimposed upon the I follower plate, the portion of the follower plate remote from the feed roller being pro vided with a recess, the penetrating member being positioned in a field of the first named member defined by said recess in the follower plate. I v
