-|MPRovEMENT IN FE'EDiNG PAPER T'o PRINTING-PRESSES.

,Specitication formingpart of Let-ters Patent No.` 33,217, dated September 3, 186i. p

To all whom t may concern: Be it known' that I, ORLANDO TALLCoTT, o Chicago,- Illinols, have invented a new and useful Machine for AFeeelliug japer to Printing `Presses;` and I 'hereby 'declarewthe following to be a full, clear, and exact description of the same, reference being had to the accom'- panying drawings and letters and igures of refe-rence` marked thereon, forming a part of this specification, in Whioh- Figure l is a perspective view. Fig. 2 isa view of the bottom of the frame C o o o o. Fig. `3 is a view of the cam G for raising the guide 1. Fig. 4 is a view of the side stop 4. Fig. 5

is a v ievi7 of Wheels a a, with wire springs h h. yh bent Vand set in the edges of the wheels ad.

, The wheels a a are supported by the guides 7 7 and run between the bars oo o o in place of the padsv 2 2, as seen in Fig. 1. The wheels a q. are caused to revolve by a belt, and the springs h h h hact o n the paper and cause it to move forward against the stops 1 1.

-In Fig. 1, A represents an endless belt of cloth on rollers. l

B is the bed of the machine. C o o o o is a frame with the Wide or front part resting on the stops 4' 4. The stops 4 4,

as seen inA Fig. 1 and 4, are side stops to 'stop the sheet When it is moved sidewise bythev sheet-zing) so as to keep the frame C o o 0 o c raised far'enough from the bed B to let the A'sheet slide freely between the bed and frame.

The front part of the stop is slottedand fastens to the. front of the bed B by means of setscrews s s, and by means of the slot'they can be adj ustedatany required distance from the ce`nter.

The upper ends of 4the -frame .C o o o o c rest in holes in the sides of the machine. The frame C o o4 o o rests on the stops 4 4 and keepsthe sheet from doubling up when the pads slide on it. `After the `sheet is in its proper place the frame C o ois raisedo from it by the guides 7 7 by means of projections that turn up at each end of C and pass through holes in the guides 7 7, thus giving room for the sheet to be taken outby the clamps of the press. The bars o o o o are bent about three inches from the plate. C, so as to rest as. near thebed ll as the plate C does. The bars o o o o are also nearer together at the npperend, so as to bring the pads 2 2 in the right place on the sheet. The bars o 0 0 0 arc about halt' an inch wider apart at the lower end, so as to allow the pads a side motion'in case one side of the sheet reaches the front stop first.

e is the bar for carrying the pads 2 2 and runs on the guides-7 7 by means of notches fitting the guides.

t' is a bar for carrying the pads 3 The ends ofthe bar t' pass through holes in the guides 7 7, s'o as to be raised with the guides.

1l l are front stops fastened to the bedplate B.

5 5 are wheels for driving the machine.

6 6 (one only is shown) are cams o n the inside of the Wheels 5 5 for raisingythe guides 7 7.

8 .is a cam o n the' edge of the wheel 5 for working the bar t' and pads 3 3.

9 is a vvheell for carrying the endles belt A.

The bar e is attached to the Wheels 5 5 by cranks. The pads 2 '2 are fastened to the bar e by means of metal knees.4 One end fastens to e and the other tothe pad. Both joints are loose pivots, thus giving the pads a free upand-down as Well as a lateral motion.

The bottoms of the'pads 2 Zand Si 3 are lined with rough rubber or any material that will cause suicient friction to draw or move the top sheet oif the pile.

3 .3 are pads lfor moving the paper-s idewise against the. side stopsl et. These pads are moved by the cam 8 acting on the end of the bar t', and the pads and bar 't' are broughtback to their place by the rubber spring n.

7 -7 are guides for. carrying the bar e and I raising the frame C o o o o.

This machine is operated as'follows: Vhen the pads 2 2 are drawn back by turning the cranks, they are raised above the paper, and Whenthe pads move forward they fall on the top. 'sheet and by means of the friction of the pad theI top sheet is carried forward till it reachesthe front stops 1 l. Il' one side of the sheet reaches the stop first, that pad will slide 'and the other side of the sheet will continue to move until it reaches the stop. Then both pads will slide until they reach the frame C When the pads 2 2 are raised off the sheet, the 4pads 3 3 drop on it and the cam 8 the stop 4. Then the pads slide on the sheet nnlil the cam 8 passes the bar Then the frame C o o o and pads e a are raised off thev sheet by means of the cams G G, whioh'allo'ws tie sheet to be taken out of `the clamps of the press. The earns 66 are so constructed that the guides 7 7 rest on the low part of the earn, thus keeping pads 3 3 raised above the sheet till the pads 2 2 cease to act. Then the pads S fall on the sheet and move it sidewise,

What I claim as my invention, and Wish to secure by Letters Patent, is

1. The use'of friction-pads forthe purpose ot moving the top sheet of a pile of paper forward against front stops, and sidewise against side stops, substantially as described.

2. Feeding the sheets between two frames or plates placed far enough apart to allow a single sheet to pass freely between near enough together to prevent th. sheet from doubling up by means of the force applied to bring it to its proper place, W .n constructed and operated in the manner V.nd for the purpose set forth, substax'itially as de scribed.

3. In combination with the pads 3'3, the adjustable side stops 4 4, the same t i be adjustable at `any required distance from the Center;

. The several devices in oombinatiomsunstantially as above set forth and described.
