PAPER-FEED -MECHANISM FOR rxrn-wnrrnas.

' To all whom/it may concern:-

Be it known that I, WILLIAM A. M00001,-

a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new anduseful Improvements in Pa er- Feed Mechanism for Ty -Writers, of w ich the following is a speci cation,reference being had therein to the accompanying drawing. p v

This invention relates to a support and feed mechanism for the sheets of paper used in a typewriter and mounted in the traveling carriage thereof. I

The invention is shown as applied to a V typewriter of the type-wheel class.

This case is a division of my application number 162,225, filed June 19, 1903. 4

' In the accompanying drawings, Figure .1 is an end elevation of the paper carriage of a typewriter embodying my invention. Fig.

2 is a vertical transverse section of the same,

showing the paper holder in. open position. Fig. 3 is a view similar to Flg. 2, except that it shows the pa er holder in closed position. Fig. 4 is a ront view of the parts illustrated in Fig. 1. Fig. 5 is afront view of the frame of the paper carria e, drawn on a smaller scale than the views a ready described. And Fig. 6 is an end view of the piece of the typewriter frame, which is milled out or otherwise shaped to form guide-ways for the paper carriage. The rame...of this carriage comprises the base iece' B, fitted to the guide-ways in the bridge 2, and to which is secured the rack bar 64 that constitutes a part of the carriage feed mechanism, that need notbe herein described in detail, and the counterpart ends 6 in which are journaled the platen 4 and the compression roller 5. The ends of the shaft of the compression roller are mounted in slots, 5, formed in the end pieces of the carria e frame, in order to permit such roller to. e moved bodilyv toward and from the platem'as may be necessary to permit a the machine;

pa er asit passes downward between the rol ers, and deflects it toward the rear of In the upper part of the carriage frame,

above the laten,.is supported'a pa er frame,

formed with the counter-part en s 113 and the curved top plate 112 extending between and connecting the end pieces. The paper frame is pivotally supported in the carriage frame, the shaft 7 serving as the means for uniting shaft and having its ends engaging respectively with the carriage frame and the paper frame serves to hold the latter nor- .mally in its upright position adjacent to the type-wheel 47, in which position'the paper frame rests algirinst stops 10 on the carriage frame. It w' be apparent from an examination of the drawings that the paper frame may berocked on its pivots and moved back away from the type wheel to expose the printing or permit the more easy manipulation of thgdpaper as may be desirable.

Journal in the paper supporting frame upon a shaft 8 is a paper guide or paperguiding frame, comprising the counter-part arms 11 and a graduated scale or space indicating bar 17. The normal position of the paper-guiding frame just described is that represented in Figs. 1 and 3 with the indicating bar 17 held close against the front "edge of thetop late 112 by the s ring 12. The frame may, owever, be'move into the position indicated in Fig.2 to permit the insertion of a sheet of paper or for other reasons. An index fin er or pointer 68 stands opposite the grafuated bar 17, being supported in any suitable manner.

The arms 11 not only extend upward to support the scale plate 17 but are also preferably extended downward and constitute supports for the brackets 114, by which is supported a cushion band 18 of thin rubber or other elastic material arranged to extend across'the frame and to form a shield between the hammer 15 and the paper that is forced by the blows of the hammer against the type upon the type-wheel 47. A knob 94-on the rod 8 outslde of one of the end pieces 113 of the frame provides a means for moving the frame in which are mounted the space bar 17 and the elastic band 18, placing these parts in such position that the paper can be easily passed down between the space them. A spring 9 coiled about the bar and" the to piece 112 and in front of the band 18, an then directed into the space between the roller 5 and the impression cyl-- ried by the end frame piece 6 of the carriage,

but is brought into engagement with the I ratchet when thelever is raised, by the spring 100. A knob 97 employed for turning the impression cylinder or platen by hand is mounted upon the shaft thereof outside the ratchet 96. A detent 115 held in a split pin 116, mounted in the frame piece 6, may be employed to engage with the ratchet wheel 96 to prevent slip or loss motion.

I11 using this inventlon the operator first turns the space bar17 forward by means of the knob 54 and inserts the paper downward behind the space bar 17 and in front of the band 18, thence down between the rollers 4i and 5; and when once inserted between said rollers, by turning the knob 97 on the roller 4 the paper may be continued to be fed downward until the upper end thereof has been brought to the proper position for the printing of the first line. The deflector 101 acts to deflect the paper in its descent toward the rear of the machine where it does not interfere in any way with any of the parts of the mechanism.

What I claim is:

1. In a typewriter, the combination of a paper carriage, a paper holder, pivotally mounted in a frame above the carriage and consisting of a graduatedspacing bar above the'pivot and a flexible band below the pivot, normally supported in a vertical osition and adapted to be rotated for the a mission of (paper between said spacing bar and band, an

a spring for returning the paper holder to normal position, substantially as set forth.

2. In a typewriter, the combination of a paper carriage, a type-carrying mechanism, a hammer cushion and a paper supporting frame carrying said cushion and yie mounted for movement toward and away from the type. v

dingly 3. In a typewriter, the combination with a suitable frame, a type carrying mechanism, a paper carriage, paper holding and feeding rollers on said carriage, and a rocking paper guide frame having a graduated scale thereon, and a hammer cushion on a said paper guiding frame.

4:. In a typewriter, the combination with a suitable. frame, a type carrying mechanism, a paper carriage, paper ho ding and feeding rollers on said carriages, a springactuated rocking pa er guiding frame having a graduated scale thereon, and a hammer cushion on said paper guiding frame.

5. In a typewriter, the combination with a suitable frame, of type carryin mechanism, a. paper carriage, paper ho ding and feeding rollers on said carriage, a rocking paper guiding frame, a graduated spacing bar at the upper part of said frame, and a yielding hammer cushion at, the lower part of said frame.

(S. In a typewriter, the combination of type carrying mechanism, a paper carriage, a paper support on said carriage yieldingly mounted with respect to the 'type, and a rocking paper guide-frame on said paper su port.

4. In a typewriter, the combination of type carrying mechanism, a paper carriage.

paper holding and feeding rollers on said carriage, a rocking paper. support on said carriage, and a rocking paper guide frame on said paper support.

- 8. In a typewriter, the combination of the printing mechanism, the paper carriage,

means for moving the carriage transversely of the type, two paper rollers mounted in the carriage horizontally opposite each other with a vertical passage way between them, means for yieldingly pressing the rollers together, a curved paper deflector below the rollers, a rotatable paper guiding frame having at its upper part a.graduated bar and at its lower part a yielding hammer band, a spring tending to retain the said frame in normal vertical position, and means for moving the said frame.

In testimony whereof I aflix my signature, in presence of two witnesses.
