To all whom it ma concern: I

Be it -known t at I, THOMAS WILLIAM KIENABT, a citizen of the United States of America, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improve-.-

ments in Feed'fnlilg Mechanisms, of which the following is. a 1, clear, and exact description, reference being had to-the accompanye ing drawings, "forming part of this specification.

My invention relates to a feeding mechanism designed for use in feeding strips or sheets of papers, such as those from which envelops'are produced in envelop machines, the present application being {a dlVlSIOH from my application" for Letters Patent of the United States, filed December 27th, 1906, NO. 349618.

, Figure I'is a side elevation of my feeding mechanism with the 1power -shaft shown in cross section. Fig. I is a rear-'elevation of the feeding mechanism. Fig. III is an enlarged elevation of the feeding mechanism viewed from the opposite side to that seen in Fig. I. Fi IV is a vertical section taken on line'IV.I Fig. III. Fi V is a vertical cross section taken on line v, Fig. IV..

1 designates a part of the frame of a na-- chine withtwhioh my feeding mechanism is to be used and which is surmount'edby a post 2 that supports a spindle 3 on which is mounted a rol A of paper from which the web is to be drawn by thefeeding mechanism to be described. Y e

4 designates a pair of feed mechanism su.p' porting membersarran ed parallel with each other and one of whic is located {adjacent totheframepartl. v

5 is a feed roller, the sp' dles of which are journaled in the support! -members 4, and to one of the s indles of which is fixed a spur wheel 6,, (see igs. I and.II) that is driven by a spur wheel 7 fixed to a drive shaft 8 that is mounted in the frame part 1 and any other suitable support and to which power may be communicated in any desirable manner.

The spur wheel 6 cooperates with the s ur wheel 7 for the purpose of drivin the eed roller 5. Upon the spindle of the eed roller 5 at the end of saidroller opposite to that to which the s ur wheel 6 is applied, is a spur wheel, 9 (see igs.-II and III).

10 designates a rock shaft mounted in the and which serve .to provide t vrarilyfseparated v V cm supporting members '4, and 1 1 are hanger arms fixed to said rook shaft and having their free ends located in proximity to the spindles of the feed roller 5.

12 is a second feed roller having its s indles journaled in the hanger arms and w ich is adapted to be moved toward and away from thefeed roller 5.. The spindle of the feed roller 12 thatis located at the end of said feed roller, corresponding to that which bears thegs ur wheel 9, has fixed to it a spur wheel 13 t atis arranged in mesh with said spur ,wheel 9, thereby providing for the rotatron of the second feed roller withthe first named feed roller, but'with the rollers rotating'in opposite directions in order'that the 5 web of paper passed between the two rollers from the roll A will be Withdrawn from said roll and fed to a desired point of delivery.

14 are tension s rings that connect the' hanger arms '11 tot e supportinglmembers 4 e requisite degree of pressure upon the web of paper,

.while it is passing betweenthe feed rollers.

It is very desirable in feedin mechanisms of the character of that descri ed herein, to provide means whereby one of the feed rollers may be held separated from the other feed roller, whilethe. web 'ofjpaper is being passed between the rollers and carried to a point at which it is to be drawn u on or o erated upon. In consideration of t 's fact, utilize meansfor holdin the feedroller 12 tempothe feed roller 5 and which I now'describe. 1 4

15'is9b1ift .pin' that is slidably fitted in one of the half er arms 1 1, and which isprovided with a knoI or handle 16. The shank of this lift dplin has a conical portion 17 located interate of its ends and between it and the inner end of the pin the shank is reduced in diameter. The reduced portion of the shank of the pin is located in a pin hole 4 in the supporting member 4, adjacent to the arm in which the'lift pin is mounted and in which the pin is held due to the existence of a stop button 18 at the inner end of the lift pin.

When the lift pin is pressed inwardlpl from the. osition in which it is seen in fu lines Fig. V to the position seen in dotted lines in the same vie'w, the conical portion 17 of the pin enters into the pin hole 4 thereby causmg the ban er arm, in which the lift in is fitted, .to be 'fted. a result of the fting of said han er arm, the rock shaft 10 is rotated, and 0th hanger arms attached to it' move simultaneously to carry the feed roller '12 journaledtherein, ina direction away from the op osing'feed roller 5 and provide 'a clearance etween the feed rollers, sumcient to pjermit the read passage of theweb of paper etween the r0 ers.- To permit the feed roller 12 to again assume its normal position and exert pressure upon the web of paper passed between the feed rollers, it ison necessary to draw the lift pin-outwardly wit the result of removing its conic'al'portion from the pin hole 4 in. the supportin mem' ber that contains it and the-feed r0 ler de scends by gravity, or is caused to return to 2. A feeding mechanism of-the character described, comprising supporting members, a pair of feed rollers supported by said sup porting members, hanger arms in which one sal esrsse N of said rollers is ournaled, and a lift in located in one of said hanger arms and a apted to be moved in the adj acent-supporting member to move the hangerarm su ported roller relative to the other roller, su stantially as set forth.

3. A feeding mechanism of the character described, com rising supporting members, a

pairof feed ro ers, hanger arms in which one of said rollers is journaled, and a lift pin slidably fitted in one'of said hanger arms and adapted to ,be moved in the adjacentsupport ing member to, move the hanger arm supported roller relative to the other roller; said ift pin being provided with a conical portion, substantially as set forth. v

4.. A feeding mechanism. of the character described, comprising supporting members, a pair of feed rollers, hanger arms'in which one of said rollers is j ournaled, and a lift pin slidably fitted in one of said han er arms and adapted to be moved inthe a jacent supporting member to move the hanger arm supported roller relative to the other roller; lift pin having. a shank provided with a conical portion intermediate of its ends and .terminatin at its-inner'end in a stop button,

substantial y as set forth. j
