To all whom it may concern:

Be it known that we, ALONZO SEDGWIOK mm, Fig. 9. Fig. 11 isa top plan view of a portion of the feed-table, underneath which the and JAMES NAYLOR, Jr., both of the city of stop mechanism is arranged. Fig. 12 is a Poughkeepsie, in the county of Dutchess and fragmentary side elevation of the machine 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 [0 that class of machines which are employed for feeding shectpaper to ruling, folding, and calendering machines, printing-presses, and other kinds of machines in which sheet-paper is used.

Our invention relates more particularly to a machine in which the feed-table on which the pile of paper is placed is automatically raised as the sheets of paper are successively fed from the top of the pile to within reach of the carrying rollers or tapes which move the sheets onward one after the other. A machine of this description is described, shown, and claimed in the pending application of Robert J. Stuart, Serial No. 119,082, filed 2 January 29, 1884:; and our invention consists of improvements on this machine, and has the object to simplify the construction of the machine and to render the same more efficient and reliable in its operation.

0 Our invention consists, to these ends, in the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of five sheets, Figure 1 is a side elevation of 5 our improved machine. Fig. 2 is an end elevation thereof. Fig. 3 is a top plan view of the machine. Fig. 4 is a sectional elevation of the holding-finger and buckling device, resting on the pile of paper in line :0 00, Fig.1.

Figs. 7 and 8 are vertical sections in lines as x and y 3 Fig. 6, respectively. Fig. 9 is a sectional elevation of the automatic clutch-shifting device, whereby the movement of the machine is stopped when the last sheet of paper has been fed from the table.

Fig. 10 is a cross-section of the same in line with the tape orpaper-carrying frame attached 5 5 thereto. Fig. 13 is a top plan view of the same. Fig. 14isalongitudinalsectional elevation in line or a", Fig. 13. Fig. 15 is a crosssection', on an enlarged scale, in line y 3 Fig. 14. Fig. 16 is a sectional elevation at right angles to Fig. 15, taken in line :0 00 of the same. Fig.1? is a side elevation, partly in section, of the holding-down finger and buckling-finger on an enlarged scale. Fig. 18 is a cross-section in line 00 a, Fig. 17.

Like letters ofreference indicate corresponding parts in the several figures.

A A represent the side frames of the machine connected by cross-stays a a.

V A represents the feed-table,upon which the pile of paper A is placed. The feed-table A is secured to supports a, which are provided near their outer ends with screw-nuts a and upright extensions a", having rollers a, which run in vertical grooves a formed on the inner 5 sides of the side frames, A, whereby the feedtable is guided in its vertical movement.

side frames, A, and provided with longitudipile of paper adjacent to the buckling device.

nal slots if.

b is an adj ustable vertical guide, secured at its ends to the brackets b by means of thumbscrews b passing through the slots b of the brackets. By this means the guide b can be adjusted backwardly and forwardly for different-sized piles of sheets placed upon the table. The upper bracket 1) also serves to support the buckling mechanism when the table A is lowered to receive a fresh supply of paper.

represents the horizontal driving-shaft, arranged transversely in the machine and supported in bearings in the side frames, A. r

0 represents a counter-shaft arranged below the driving-shaft O and parallel with the Motion is transmitted from the driving-shaft Q by a train of gear-wheels, c c 0 in such manner that the speed of the countershaft 0 can beincreased or reduced by changing the size of the gear-wheel c and adjusting the size of the gear-wheel c accordingly.

0 represents a clutch-coupling whereby the driving-pulley O" can be thrown in and out of gear, as desired.

D represents ahorizontal rock-shaft, arranged at right angles to the shafts O O, and supported in bearings d (1, formed on one of the side frames, A; and D represents a similar rock-shaft arranged parallel with the shaft D, and above the same, and supported in bearings d 61, formed on the side frame, A.

D is a strap or link connecting the shafts D D near their outer ends, so as to prevent the same from springing or bending when they are extended, as shown in Fig. 1. The strap D is held from lateral displacement by the finger F and a collar, D, which are secured to the shaft D on opposite sides of the strap D.

E represents an upwardly'extending arm, secured to the shaft D, and to the upper end of which the buckling device is attached.

E represents an elbowlever, which is pivoted to the inner side of one of the side frames,A, by means of a pivot-bolt, c.

E represents a lever secured to the rockshaft D by means of a set-screw, e. Thelever E extends inwardly through an elongated opening or slot, 6", formed in one of the side frames, A,whereby the lever and the shaft D are held from lateral displacement. The setscrew 6 of the lever E engages in a longitudinal slot or groove formed in the shaft D, so that by loosening the screw 6 the shaft D may be moved laterally in its-bearings,to adjust the arm E and buckling device attached thereto to the different sizes of sheets of paper.

e is a vertical rod connecting the inner end of the lever E with the horizontal arm 0 of the elbow-lever E. e is the vertical arm of elbow-lever E, which is bifurcated to engage over a cam, e, secured to the counter-shaft 0, whereby motion is imparted to the lever E, rod e ,'lever E and rock-shaft D.

F represents a finger which is secured to the end of the shaft D by aset-screw, f,and which rests with its free end upon the corner of the The finger F is held down upon the pile of paper by means of an arm, F, which is secured to the shaft D by a set-screw, f, and a spiral spring, f which is secured at its upper end to thearm F, and at its lower end to the frame A by a screw, f and thumb-nutf The shaft D is held from lateral movement by means of two sleeves, 02 which surround the shaft and are arranged between the. bearings d and the arm F. The outer ends of the sleeves abut against the inner sides of the bearingsd, and their opposite ends against the arm F. By loosening the set-screwf of the armFthe shaft D can be adjusted in its bearings, and the finger F, which is secured to the outer end of the shaft, is thereby adjusted, so as to rest upon the corner of the pileof paper. B

tightening the arm F upon the shaft D, the

further lateral movement of the shaft is prevented by the sleeves or collars (P.

G represents an auxiliary vertical tensionrod, which is guided at its upper end in the arm F, and near its lower end in a lug, 9, formed on the frame A.

g is a pin or split key inserted through an opening in the rod G, above the arm F, and g is a spiral spring which surrounds the rod G between the lug g, and a thu mb-nut, y, engaging over the lower threaded end of the rod G. The tension of the spring g holds the rod.

G with its pin 9 against the arm F, thereby increasing the pressure of the finger F upon the pile of paper.

G represents an elbow-lever, which is pivoted at g to the inner side of one of the side frames, A. The rod Gis provided with a reduced portion, 9 over which engages the bifurcated end 9 of the elbow-lever G, so as to hold the rod G in an elevated position and relieve the arm F from the tension of the spring g The elbow-lever-G is actuated by a cam, 9 on the counter-shaft G in such manner that while the top sheet of paper is being withdrawn from under the finger F the latter is relieved from the additional pressure of the spring 9 and rod G, the finger F at this movement being held down upon the pile by the springf alone. \Vhen the top sheet has been removed from under the finger F, the rod G is released by the elbow-lever G and cam 9 and the pressure of the spring 9 forces the rod G downward, and bearing upon the arm F increases the pressure of the finger F upon the pile, whereby the pile is more securely held in place upon the feed-table.

H represents the buckling-finger, which is pivoted to the upper end of the rock-arm F by a bolt, h, passing through a slot, h, in the rockarm, so that the finger can be adjusted back ward or forward, as may be desired. The free end of the finger H is bifurcated, and is provided with a roller, If, of rubber or other suitable material,which is provided with journals h The journals h of the rollers are seated in elongated openings h, formed in the jaws of the bifurcated portion of the finger H.

in such manner that the journals move back wardly in the openings h when the roller moves forwardly over the paper during the buckling operation, and so that the journals rest against the front ends of the openings h when the roller moves baekwardly over the paper toward the finger F.

h is a bladesecured to the upper side ofthe finger H, and having its sharp front edge arranged at a short distance in rear of the roller h, so that the latter can turn freely when the journals rest in the front portions of the openings h, but will impinge against the blade and prevent the roller from rotating when the roller-journals are moved backwardly in the openings 7?. \Vhen the finger H is moved forwardly over the paper, the pressure of the roller upon the paper causes the roller-journals to move backwardly in the openings h* until the blade h impinges against the roller. The roller is thereby prevented from turning, and moves over the paper like a fixed bearingpiece. During the backward movement ofthe roller thejournals of thelatter move forward ly in the openings h" until they rest against the front ends of the openings h, in which po sit-ion the roller is free to turn, and conse quently rolls over the paper during the backward movement of the finger.

Irepresents a finger, which is pivoted to the rock-arm E above the finger H by a bolt, i, passing through a slot, 2 in the rock'arm, so that the finger may be adjusted backward or forward, as may be necessary. The free end of the finger I is bifurcated, and is pro vided with a roller, i preferably of metal, which is provided with journals Thejournals of the roller 2' are seated in openings in the bifurcated portion of the finger I in the usual manner, so that the roller 2' may turn freely when the finger I is moved forward or backward. The finger I is made somewhat longer than the finger H, so that its roller will move over the top sheet of the paper a suitable distance in front of the buckling-roller If, to permit the latter to buckle the top sheet against the roller i is a roller or stud attached to the under side of the finger H, and adapted to ride upon the upper side of the finger F during the last portion of the backward movement of the finger H.

i is an adjustable foot, secured to the finger I. and which is adapted to rest upon the top of the finger H when the latter, in its backward movement,rides upon the finger F, so that both fingers are elevated ashort distance above the pile and away from the top sheet, and their pressure added to the finger F, whereby the pile is more securely held in place on the feed table.

i 1' are spiral or other suitable springs, secured, respectively at their upper ends to the fingers H and I and at their lower ends to projectionsi" ofthelever E, by means of screwstemsi and thumb-nuts i. The springs 73 i serve to hold the fingers down upon the paper during their forward movement, and also serve to increase the pressure on the finger F when the fingers H and I rest upon the same.

We prefer to construct each of the fingers F, H, and I in two parts, connected together by swivel joints h [L7, whereby the rollers or other portions of the fingers which bear upon the top sheet are enabled to assume an inclined position and adjust themselves to the inequalities of the upper surface of the pile. The swiveling movement of the end portion of each finger is limited by the overlapping portions h of each finger.

J represents a gage or foot, which rests upon the top sheet, and which serves the double function of regulating the upward feed-n1otion of the table A and of holding the pile of paper in place. The foot J is arranged in such close proximity to the buckling-finger H that it may be used in connection with the buckling-finger H as a buckling device. The foot J is preferably made of a block of rubber or other elastic material, and seated in a soeket,j, which latteris provided with an upwardly-projecting screw'stem, j, which worksin a threaded opening formed in a horizontal armJ, and is secured in position, after being adjusted, by a jam-nut, j. The arm 9' is attached to an inwardly-projecting arm, j, by a vertical bolt,

j passing through a longitudinal slot, j", in

the arm 7', whereby the foot J can be adjusted as may be required. The arm j is provided with a vertical socket, j, which is secured to a vertical bar, K, by means of a set-screw, j The socketj of the arm j is arranged upon the bar K, between two sleeves or collars, k k, in such manner as to permit the arm j to swing on the rod K between the collars k is when it is desired to change the position of the foot to adapt it to differentsized sheets of paper. The rod K is guided at its upper and lower ends in lugs It 10 formed on the adjacent side of the frame A.

k is a socket or stem secured to the rod K above the lug it, and which is provided with an outwardly projecting stud or arm, k, guided in an elongated opening or slot, formed in the frame A. The socket k is adjustably secured to the vertical rod K by means of a set-screw, k.

L is an elbow-lever pivoted to the side frame, A, at l, and having its long arm bifurcated at l, and engaging over the projecting end of the stud k". The short arm 1 of the elbow-lever L is provided with a roller, Z which is operated upon by a cam, Z, secured to the countershaft 0, and formed in such manner that it will cause the foot J to be lifted from the top sheet when the latter is ready to be withdrawn from under the foot J by the feeding device. The foot J is held down on the top sheet by a spring, 1", surrounding the lower end of the bar K, and which is interposed between the lug It of the frame A and a pin or washer, l, on the bar K.

M M represent the feeding-fingers, whereby the top sheet is fed from the pile to the carry- ICO ing-rollers. The fingers M M are bifurcated the ratchet-rim I) by a spring, 0, which is at their lower ends and provided with rollers m m, and a stop device like that of the buckling-finger H, so that the rollers mm operate like a rigid bearing-piece in moving forwardly, and carry the sheets of paper in their forward movement, and roll over the underlying pile of paper in moving backwardly. The fingers M M are pivoted at their upper ends to rock-levers M M by bolts m m passing through slots m", formed in the rock-levers M M, so that the fingers M M may be set at any desired angle. The rock-levers M M are adjustably secured at their upper ends to a horizontal rock-shaft, M by set-screws m The set-screws m engage in a longitudinal slot formed on one side of the rock-shaft M", whereby both rock-levers are held in parallel lines, thereby facilitating the adjustment of the fingers M M when it becomes necessary to adjust the fingers to different sizes of sheets. The rock-shaft M is supported in bearings m formed on the frames A A.

m is an arm arranged at an angle to the rock-levers M M, and secured to the rockshaft M by a screw-nut, m.

m is a vertical rod connecting the arm on with the end of the long arm of an elbow-lever, N. The lever N is pivoted at n to the inner side of one of the side frames,A, and the short arm n of the lever N is provided with a roller, 12, which engages in a cam-groove, a, formed in the disk N, secured to the counter-shaft O, by means of which an intermittent reciprocating movement is imparted to the fingers M M. The rock levers M are provided with fiat springs m, arranged on the sides adjacent to -the fingers M, so as to bear against the same when they are placed in an elevated position above the pile, and hold the fingers up away fromthe work when required.

orepresents a pawl,which engages with the ratchet-rim b ofthe hand-wheel B. The pawl 0 is pivoted to the upper end of an elbowlever, O, which is pivoted to the outer side of the side frame,A.at 0. The lower arm of the lever O is provided with a roller, 0 ,.which is operated upon by a cam, 0 secured to the counter-shaft O. The cam o is so formed that it will impart a rocking motion to the lever 0, thereby moving the pawl 0 back and forth over the ratchet-rim b 0 is a projection or nose formed on the lower arm of the lever O, and which engages against a shoulder, 0 on the outer side of the lever L, whereby the stroke of the lever O and the motion which the pawl 0 produces in the ratchet-wheel b are regulated. In the same measure as the foot J descends by the removal of the sheets from the top of the pile the lever L and the stop 0 descend also, whereby the oscillation of the lever O and the stroke of the pawl 0 are increased, so that the rotation of the wheel B and the feed-screws Zrb is proportionate to and controlled by the amount of paper which is removed from the top of the pile. Thepawl o is held in engagement with seated upon a lug, 0, on the lever O, and surrounds a sliding rod, 0, attached at its upper end to the pawl 0. its upper end against a pin or collar on the rod 0 thereby pressing the pawl upward against the ratchet-rim b and keeping the same in engagement therewith.

In order to lower the feed-table, the pawl 0 is disconnected from the ratchet-rim b when the feed-table can be lowered by hand for supplying a fresh charge of paperto the machine.

P represents the grooved tape-roller, arranged in front of the feed-table A, with its upper surface in line with the top sheet, so as to receive on itsupper surface the top sheet as the latter is removed from the pile by the fingers M.

P are rollers mounted upon a horizontal shaft, 1), and faced with india-rubber or other suitable material, so as to bite against the paper when broughtin contact therewith. The shaft 19 isjournaled in arms 1) p, suspended from a transverse rock-shaft, pfiwhich is journaled in the side frames, A. Theshaft p is supported by the arms 1), so that the rollers P will rest by their weight upon the taperoller P. I

P" represents an adjustable carrying-frame, attached to the frame A, as shown in Figs. 12 and 13, by pivot-bolts p and supporting-arms 19 The upper ends of the armsp are pivoted to the frame P by one of the stay-bolts p of the frame P The lower ends of the arms 19 are bifurcated or slotted, and are secured to the frame A by bolts 12*, which engage in the slotted ends of the arms 19 so that the inclination of the carrying-frame may be varied as required.

p is a grooved tape-roller, journaled in bearings in the outer end of the frame P and p are the endless tapes,which are arranged over the rollers P and p", and which deliver the The spring 0 bears with IIO sheets of paper to the machine in which they 7 are to be operated upon.

P is a channel-guide secured to one of the sides of the frame P by screw-bolts p. The latter are preferably provided with right and left hand screw-threads, and are arranged in screw-threaded openings in the frame P The inner ends of the bolts p engage in threaded openings formed in lugsor bearing-pieces p, secured to the under side of the guide 1?, whereby the guide can be adjusted to a true line.

P is a similar guide, arranged upon the frame P obliquely to the sides of the frame, and adapted to guide the sheets toward the guide P The guide P rests upon the staybolts 19, and is held thereon, near its inner end, by a U-shaped clip, 10, which fits over the bolt p and near its outer end by a clip or clasp, p which bears against the under side of the stay-bolt p". The guide P can be ad- 4o feed-table A, and supported and guided by a P" is a spring-finger, which is preferably formed by curling a piece of card-board or similar material, and which is secured in a vertical clasp, 12, attached to the guide P, and which also serves to force the paper against the guide P The tapes 1)" are preferably arranged obliquely in the frame P, so as to cause the sheets of paper to be carried toward the guide P". The sheets move with their outer edges in the guide P which lat ter serves to deliver the sheets at the proper place to the machine or apparatus in which they are further operated upon.

S represents a cone-pulley mounted on the shaft 0, and S is a similar cone-pulley, formed with or secured to the roller I. Motion is im parted to the pulley S from the cone-pulley S by means of an endless belt, 8, or in any other suitable manner.

T represents the shipper bar or lever whereby the elutch c is thrown in and out of gear, and the motion of the machine arrested when desired. The bar T is supported at one end in a bearing, t, formed on the frame A, and is provided with a finger or bar, t, which engages in the annular grooves of the clutch 0 The opposite end of the bar T is pivoted at t to a vertical handlever, t, which is pivoted at its lower end to the frame A by a pivotbolt, 2?. By moving the hand-lever 2, backward the shipper-bar T is shifted, and the motion of the machine arrested.

t represents a horizontal rock-lever pivoted at t to the frame A, and connected at its outer end to the upper end of the hand-levert", and provided at its inner end with adownwardly projecting finger, i

B represents a horizontal shifting plate, which is arranged on the under side of the horizontal channel-plate, 1', secured to the under side of the feed-table. The plate B is provided at its outer end with an elongated slot or opening, r, and is so arranged that when the table is raised to nearly the limit of its upward movement the opening I" will engage over the finger or pin t of the rock-lever t r is a downwardlyprojecting arm or lug formed on or secured to the plate 1, and 7" represents a vertical bifurcated pawl or lever pivoted at its lower end to the arm 1*, and having its upper end extending through aslot, 0', formed in the table A.

0' represents a bell-crank or elbow lever, pivoted at r to the under side of the table A. One arm of the lever r is pivoted to the shifting plate R, and the opposite arm of the lever r engages in the bifurcated portion of the pawl or dog 1'.

0 represents a spiral spring, secured at one end to the elbow-lever r and at its opposite end to the arm 0", whereby the shifting lever B is held with its outer slotted end in a forward position, in which position the slot 1' of the lever B will engage over the finger i of the lever '6 when the table has reached the proper height.

The slot 1-, which is formed in the table A, is arranged in line with one of the feeding-fingers M, so that the feed-roller in feeding the paper from the pile will roll in a line directly over the slot. The upper end of the pawl 0r lever 7' projects through the slot 1", so that its upper end will be nearly in line with the top of the table, but will not extend above the same.

a represents apawl or linger pivoted to one of the feeding-fingers M, so as to rest with its free end upon the pile of paper. XV hen the last sheet of paper has been fed from the table A by the feeding-fingers M, the pawl or finger u drops into the slot 1*, so that its free end engages against the upper end of the pawl or lover I, and moves the same forwardly in the slot 1'. During this movement of the pawl r the shifting plate R is moved inwardly by the bell-crank lever r engaging with the pawl W, and the finger i of the rock-lever i being now engaged in the slot 1' of the shifting-lever R, will cause the roek-lever t to swing on its pivot and shift the hand-lever i, whereby the further move- -ment of the machine is automatically stopped.

By disengaging the finger u from the pawl 'r, the shiftinglever and the pawl r are again brought back to their former position by the action of the spring W. The slot r of the lever B is made sufficiently long to permit of this movement without disturbing the shipper-bar T. The table can now be lowered for a fresh supply of paper by turning the hand-wheel B. To again start the machine it is only necessary to give the hand-lever t a suifieient forward movement to cause the clutch c to engage with the driving-wheel, when the finger or pin 15 and slot 0" are again in a vertical line, ready to engage when the table has reached the proper height.

V represents a handwheel, provided in its hub v with an internal screw thread which engages with an external screw-thread, a, formed on one of the stay-rods a, which connect the side frames, A A, of the machine.

c" v are upwardly projecting studs or lugs, formed 011 one of the plates 12*, and arranged on opposite sides of the hub of the wheel V, whereby the wheel is confined between the studs and prevented from moving longitudinally over the screw-thread o. By turning the wheel V in one or the other direction the threaded hub o, engaging with the screwthread a, causes the machine to be moved longitudinally on the plates v", whereby the position of the machine can be adjusted with reference to a ruling or other machine which receives the paper from the feeding-machine.

the top sheet.

- sheet from under the finger F, and buckles the corner of the sheet against the roller 45 of the finger I, thereby separating the top sheet from the pile. The fingers H and I on their return movement are raised from the separated sheet by the finger F, and ride upon the latter. The tension-rod G is released at the same time by the action of the cam g on the lever G, and these parts add their combined pressure to that of the finger F, thereby holding the latter tightly upon the pile of paper. The foot J is now lifted from the top sheet by its actuating mechanism, and the fingers M begin their forward movement and cause the top sheet to move toward the rollers Pand 1? until the latter grip the front edge of the top sheet. The sheet is then fed forward by the rollers I P upon the carrying-tapes. After the fingers M lWI have completed their forward movement,they are brought back by the action of the grooved cam N and connecting parts, and when they have reached the limit oftheir backward movement they remain at rest upon the top sheet until the .buekling device has again moved forward and buckled the top sheet. WVhen the buckling fingers have returned and rest upon the top of the finger F, the feeding-fingers M again begin their forward movement and carry the top sheet between the rollers P P, and so the movements of the parts continue until the last sheet has been fed from the table A, when the pawl u drops into the slot r in the table and engages against the lever riand thereby shifts the clutch mechanisnrand stops the movement of the machine.
