Application filed January 29, .1884.

To ctZZ whom, it may concern: I

Be it known that I, ROBERT J. STUART, of the city of Foughkeepsie, in the county of Dutchess and State of New York,have invented new and useful Improvements in Paper- Feeding Machines, of .which the following is a specification.

This invention relates to an improvement in that class of machines which are employed for feeding sheet-paper to ruling, folding, and calendering machines, printing-presses, and other kinds of machines in which sheet-paper is used.

The invention relates more particularly to a machine by which the top sheet is removed from the pile of paper by turning the top sheet so as to separate it from the pile and bring it within reach of the carrying rollers or tapes which move the sheets onward one after another.

A machine of this description is described,

shown, and claimed in Letters Patent of the United States No. 282, 014, granted tome July 24-, 1883; and my present invention consists of improvements on this machine, and has the object to render the machine more efficient and reliable in its operation. i

My invention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of five sheets, Figure l is a side elevation of my improved machine; Fig. 2, an end elevation of my improved machine. Fig. 3 is a top plan view of the machine. Fig. 4. is a vertical sectional elevation of the pivot'resting on the paper and the parts connected therewith. Fig. 5 is a horizontal section of the horizontal arm secured to the upper end of the pivot-spindle. Fig. 6 is a side elevation of the mechanism whereby the upper carrying-rollers are raised and lowered. Fig. 7 is a cross-section of the side frames and feedscrews. Fig. 8 is a' horizontal section in line as m, Fig. 7. Fig. 9 is a side elevation of the gear mechanism whereby the counter-shaft is driven from the driving-shaft. Fig. 10 is a side elevation of the device whereby the rocklever of the buckling mechanism is actuated. Fig. 11 is a side elevation of 'the mechanism whereby the pivot-lifting device is actuated. Fig. 12 is a longitudinal sectional elevation (N0 model.)

Fig. 14 is a in which is fitted the lower end c is a tubular bearing or sleeve, in which the" upper portion of the spindle 0 turns, and whichpasses through ascrew-nut, c". The latter is fitted in an elongated opening, d, formed diagonally in a transverse brace or bar, D, which connects the upper ends of the sidev frames, A. The screw-nut c is secured in position in the elongated opening 02 by a handnut, 0, applied to the upper end of the externally-threaded sleeve 0" and bearing against the upper side of the slotted brace D, and a collar or flange, 0 formed at the lower end of the sleeve 0 and bearing against the lower side of the slotted brace D, as represented in Fig. 4. Upon releasing the hand-nut c the nut c is loosened in the slot d and can be adjusted back and forth in the same, thereby adjusting the pivot 0 toward or from the middle ofthe feed-table, as may be necessary with sheets of different sizes. The pivot G has a limited vertical movement on the spindle c.

E represents acurved arm, which is rigidly secured with its upper end to the spindle c, and which is provided at its lower end with a bifurcated bearing, 0, in which turns ahorizontal shaft, 6.

. 6 represents an arm, which is firmly secured to the horizontal shaft 6, between the jaws of the bearingaand which straddles with its bifurcated end a the upper portion of the pivot G. The latter is provided with recesses or depressions e in which the ends. e of the arm 6 engage, so that the horizontal shaft 6 receives a rocking motion when the pivot O israised or lowered.

F represents the fingers, which are secured to the horizontal shaft 6 and provided at their ends with bearing-pieces f, of rubber or other similar material, which rest upon the paper and turn and move the top sheet during the forward movement of the fingers.

g is a horizontal rock-shaft, which is supported in bracket-bearings G G, secured to the ends of the slotted central portion of the cross-piece D.

g is an arm, which is secured to the rockshaft g,and which straddles withits bifurcated end the upper portion of the pivot O. The latter is provided with an annular groove, 9, in which the bifurcated end of the arm 9 engages, so that the pivot can be raised and lowcred on the spindle c by the arm while the pivot is being turned.

H represents an arm secured to the upper end of the spindle c for turning the same, and h is a connecting-rod, whereby the arm H is connected with the actuating rock-lever I. .The arm H is provided with a slot, h, in which is arranged an adjustable block, 7L2, which can be moved toward and from the spindle e by an adjusting-screw, h ,.and which is clamped by a screw-nut,, h, in position in the slot h after it has been adjusted. The block h is provided on the outer side of the arm H with a vertical socket in which is pivoted a bifurcated carrier, h to-which the inner end of the connecting-rod h is attached by a horizontal bolt, h". This bolt forms a universal joint with the vertical pivot h by which the carrier h is attached to the block h", thereby giving the connectingrod h the requisite freedom of movement.

j represents the horizontal driving-shaft, arranged transversely in the machine and sup ported in bearings in the side frames, A. j

represents a counter-shaft arranged below the driving-shaft j and parallel with the same. Motion is transmitted from the driving-shaft j by a train of gear-wheels, J J J in such manner that the speed of the counter-shaft j can be increased or reduced by changing the size of the gear-wheel J and adjusting the gear-wheel J accordingly.

J 3 represents a clutch-coupling,whereby the drivingpulley J 4 can be connected or disconnected, as desired.

j represents a rock-shaft arranged in rear of the driving shaft j and parallel therewith. The rock-arm I is secured to'the rockshaft j, and the latter is set in motion by an eccentric, I, secured to the counter-shaft j and connected with a downward extension, i, 'of the rock-arm I. The upper end .of the rock-arm I is connected with the connecting-rod h by a universal joint composed of a bearing, 2', secured to the upper end of the arm I by a horizontal bolt, i, and a bearing, f, in which the outer end of the connecting-rod is secured, and which is attached to the bearing 2" by a vertical bolt, v3 1 K represents an elbow lever,whieh is mounted loosely upon the roek-shaftjfland provided at the end of its lower arm, 7c,with a roller, k.

76 is a cam secured to the counter-shaft j, opposite the roller 75, so as to actuate the elbow-lever K.

k represents the upper arm of the elbowlever, and 7a a rod, whereby this arm is connected with an arm, 7?, secured to the horizontal rock-shaft g. The cam k moves the lower arm of the lever K forwardly, and thereby rocks the shaft 9 in its hearings in an upward direction, which movement is transmitted by the arm 9 to the tubular pivot O, and from the latter through the arm 0 to the rock-shaft 0", whereby the fingers F are lifted from the paper. This movement occurs when the fingers F have completed their forward movement, and the parts are'held in this elevated position by the cam k until the fingers have completed their backward movement, when the cam releases the lever K and thereby permits the parts to descend to their former position, in which the pivot O and fingers F rest upon the top sheet.

The forward and backward movement of the fingers F is effected by the rock-arm I and the parts whereby the said rock-arm is connected with the spindle c, and the tubular pivot 0 turns on the spindle c with the fingers by reason of, the arm e engaging in the recesses e of the pivot.

The arm 9' is made adjustable on the shaft 9, so that it can follow the adjustment of the pivot in the slot d of the bracket D.

Zrepresentsafinger, which is pivoted to a bracket, L, secured to a cross-piece, L, connecting the side frames, A, and which rests with its free end upon the corner of the pile adjacent to the buck-ling device. The finger Z is held down upon the paper by aspiral spring,

aiaasi 3,

Z,which is secured to a collar, 1*, on the rockshaft j M represents the buckling-finger, which is pivoted to the rock-arm I by a bolt, m, pass ing through a slot, m, in the rock-arm, so that the finger can be adjusted backward or forward, as may be necessary. The free end of the finger M is provided with a bearingpiece, m of rubber or other suitable material, resting upon the paper in front of the finger Z.

m is a roller or stud attached to the finger M, and adapted to ride upon the upper side of the finger Z during the last portion of the backward movement of the finger M, whereby the finger is lifted from the paper and its pressure added to that of the finger l,whereby the pile is more securely held in place on the feed-table.

n represents a supplemental pressure-finger adapted to bear upon the further corner of the pile on the same side of the machine on which the finger Z is arranged. The finger n is attached to an elbow-lever, N, which is pivoted to the bracket L at n. The finger n is secured to the lever N by a bolt, a, passing through a longitudinal slot, a, in the upper arm of the lever N, so that the finger a can be adjusted toward or from the finger Z, according to the size of the sheets operated upon. The elbow-lever N is actuated by a cam or crank, a, secured to the counter-shaft j in such manner that the finger n is lifted from the top sheet when the same is moved out from under the finger by the fingers F. At all other times the finger a is held down upon the top sheet by a spring, or, connecting the upper arm of the lever N with the stationary frame of the machine.

0 represents a gage or feet, which rests upon the top sheet between the fingers Z and n, and which serves the double function of regulating the upward feed motion of the table A, and of operating, in connection with the finger M, as a buckling device. During the forward movement of the finger M the foot 0 rests upon the top sheet in front of the bearing-piece m of the finger M, whereby the top sheet is buckled and separated from the pile, as represented in Fig. 12.

The foot 0 is provided with an upwardly projecting screw-stem, 0, which works in a threaded opening in a horizontal arm, 0, and is secured in position on the same after being adjusted by a jam nut, 0 The arm 0 is attached to an inwardly projecting arm, 0', formed on an upright rod, 0 The arm 0 is attached to the arm 0 by a vertical bolt, 0, passing through a longitudinal slot, 0 in the arm oflwhereby the position of the foot 0 can be adjusted with reference to the bucklingfinger M as may be necessary in order to properly buckle the top sheet. The upper end of the rod 0 is guided on the adjacent side frame, A, bya horizontal bolt, p,which passes U through a vertical slot, 1), in the side frame.

The lower end of the rod 0 is attached to an elbow-lever, P, which is pivoted to the side frame, A, at p, and which has its short arm 19 provided with a roller, 1). The latter is operated upon by acam, p secured to the counter-shaft j, and formed in such manner that it will cause the foot 0 to be lifted from the top sheet when the latter is ready to be withdrawn from under the foot 0 by the fingers F. The foot 0 is held down on the top sheet by a spring, 1)", connecting the arm 0 with the stationary frame of the machine.

q represents a pawl, which engages with the ratchet-rim b on the hand-wheel B. The pawl q is pivoted to the upper end of an elbow-1ever, Q, which is pivoted to the outer side of the adjacent side frame, A at q. The lower arm of the lever Q is provided with a roller, 1 which is operated upon by a cam, Q3, secured to the counter-shaft j. The cam g is so formed that it will produce a rocking motion in the lever Q, thereby moving the pawl q back and forth over the ratchet-rim I)".

is a projection or nose formed on the lower arm of the lever Q and engaging against a J shoulder, Q5, on the outer side of the lever P, whereby the stroke of the lever Q and the motion which the pawl q produces in the ratchetwheel I) are regulated. In the same measure as the foot 0 descends by the removal of the sheets from the top of the pile the lever l and the stop q descend also, whereby the. oscillation of the lever Qand the stroke of th( pawl q are increased, so that the rotation 01 the wheel B and the feed screws is propertionate to and controlled by'the amount of paper which is removed from the top of the pile. The pawl q is held in engagement with the ratchet-rim b by a spring, r, which connects the heel of the pawl with a lever, It, pivoted to the outer side of the adjacent side frame, A at r. The end of the lever B adjacent to the upright rod k is bent at right angles to the main portion of thelever R, which extends along the outer side of the side frame, A. This bent portion of the lever It engages under a stop, 0, on the rod 0, and a stop, 9', on the rod is".

Upon depressing the handle 1' of the lever It, the bent portion of the lever It is raised, thereby raising the rods 0 and 7c" and lifting the foot 0, the pivot 0, and the fingers F from the pile. The spring r is released at the same time, thereby disengaging the pawl q from the ratchetrim N. The feed-table can now be lowered for supplying a fresh charge of paper to the machine by turning the handwheel B. The lever B can be locked in this position d uring this operation by a turn-button, r, pivoted to the side frame.

S represents the grooved tape'roller, arranged in front of the feed-table A, with its upper side in line with the top sheet, so as to receive on its upper surface the top sheet as the latter is removed from the pile by the fingers F. The roller S is provided with carrying-tapes in any usual and wellknown manner.

S are rollers mounted upon a horizontal cam, 8 mounted on the countershaft j and engaging with a bell-crank lever, s, which is pivoted to .the inner side of the adjacent side frame, and provided at the end of its lower arm with a roller, 8, which bears against the eccentric s". The upper arm of the lever s is connected with one of the arms .9 by a connecting rod, .9. The eccentric s is so formed and arranged upon the shaft that the rollers S are held in an elevated position, as represented in Fig. 6, while the top sheet is being fed on the roller S, and so that the rollers S are lowered and caused to press upon the top sheet when the front portion thereof has been properly placed on the roller S. In this position of the rollers S the top sheet is clamped between the rollers S S, and thereby moved forwardly on the tapes which pass around the lower roller, S. When the sheet has cleared the rollers S'S,the rollers S are again elevated by the abovedescribed mechanism. I

The operation of the machine is as follows: The pile of paper being placed upon the feedtable A, the fingers Zand a, the foot 0, the pivot G, and the fingers F all rest upon the top sheet. The forward movement of the finger M draws the corner of the top sheet from under the finger Z, and buckles the corner of this sheet against the foot 0, thereby separating the top sheet from the pile. The re turn movement of the finger M carries the corner of the top sheet back upon the finger Z, the end of the latter being sharpened to allow the sheet to slide upon the top of the finger. The finger M, resting on the finger Z, holds the latter more tightly upon the feed-table. The curvilinear movement of the fingers F now causes the top sheet to be turned on the pile toward the rollers S S, and the foot 0 and finger a are lifted by their actuating mechanism in order to permit the fingers F to move the top sheet away from under the finger a and the foot 0. In turning the top sheet on the pile toward the rollers S S, the pivot 0 acts as a center or fulcrum on which the top sheet turns. The forward movement of the fingers Econtinues until the front edge of the top sheet has been squarely placed upon the roller S. "When this has been accomplished, the rollers S descend and grip the front vedge of the top sheet, and the latter is now fed forward, by the rollers S S, upon the carryingtapes. Before the top sheet has been gripped by the rollers S S the fingers F and the pivot O are lifted from the pile by the action of the cam k and connecting parts, to allow the turned top sheet to be carried off by the rollers, and are held in an elevated position during the return movement of the fingers. When the fingers F have completed their returnstroke, they are again dropped, together with the pivot 0, upon the paper, and the next forward movement of the fingers begins, whereby the sheet which is now on the top of the pile is turned and moved forward between the rollers S S. 1

By changing the position of the pivot G in the elongated opening d and properly adjust= ing the parts connected therewith, the mechanism whereby the top sheet is turned and moved forward is adjusted to the size of the sheet operated upon.

In Fig. 3 the position of the pile of paper on the table is indicated in fulllines, and the top sheet is represented in dotted lines in one of the positions which it assumes while it is being turned on the pile.
