. IMPROVEMENT IN PAPER-FEEDERS.

Specification forming part of Letters Patent N0. 113,291, dated April 4, 1871; antedated April 1, 1871.

with ribbed rubber coveringnear each end, takes the paper from the balauceboard, one' end of which touches the under side of said roller, and bythe friction of the rubber passts the paper over the feed-board to the rulingmachine or other machine withwhich it maybe used. Said feed-board is covered with rubber to prevent by a counter-friction more than one sheet passing at a time. 7 The'roller B is to be connected with the ruling-machine by tapes or cords.

The second part of my invention relates to an axle with a wheel on one end and an eccentric on the other end, combined with a lever worked by said eccentric so as-to tip the balance-board in order to cause an interval be tween thepassa'ge of the several sheets.

Description of the Accompanying Drawing.

A is the frame of the feeder.

Bis the feeding-roller, suitably journaled in frame A, and b b are the ribbed rubber covers near each end of said roller.

0 is the balance-board, centrally pivoted, as shown, which'holds the paper to be fed.

D is the feed-board, with" rubbercovering to prevent more than one sheet passing at a time.

E is the axle to which the wheel and eccentrio are attached. r

F is the wheel, turned by'a belt.

Gis the eccentric, working against the lever H, by which the balance-board O is tipped.

The paper is placed upon the balance-board 0, which turns upon two journals ,fixed a little forward of the center. The paper being thus placed, the end of the upper sheet touches the under side of the ribbedrubbercoverings of the roller B. This roller is kept constantly revolving,"either by bands or cords passing from this roller tothe machine which it feeds, or else by a band passing round the end of one of the journals of this roller. By the friction of said ribbed rubber coverings the top sheet is passed forward over the feed-board l) to the ruling or other machine to, be fedp' The lever H being'moved by the ecccntij'icG, which eccentric is kept revolving by a band on the wheel F, said lever H, after one sheet has been fed, tips the balanceboard'G, thereby making an interval before the next sheet is fed. When sufficient interval has elapsed, which will be regulated by the size of the wheel F, theeccentric allows the lower end of thelever to rise, thereby releasing the balance-board-from its influence. The front end of the balance-board, with the remaining sheets, again comes up to the roller B, and another sheet is passed forward over the feedboard D to the machine to be fed. Should two sheets adhere and be taken up together by the coverings b b, the under sheet will be stopped by the friction of the rubber covering on said feed-board D, said covering being put on the board D for that purpose.

Claims.

that I- claim as my invention, and desire to secure by Letters Patent, is-

. ranged substantially in the manner and for purpose set forth in the preceding description.

'2. The. shaft E and eccentric G, attached thereto, in combination with the lever H and balance-board 0, provided with acrank-axis, all arranged in relation to each other in the manner described, and for the purpose specified.
