ROBERT J. STUART. OF POUGHKEEPSIE, NE\V YORK, ASSIGNOR TO THE SEDGJVICK MANUFACTURING COMPANY, OF SAME PLACE.

PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 327,617, dated October 6, 1885.

A pplicaiion filed June (3. 1851. Serial No. 35,011.

To all whom it may concern.-

Be it known that l. ROBERT J. STUART, residing in the city of Poughkeepsie, Dntchess county, and State of New York, have invented a new and Improved Machine for Feeding Sheet-Paper; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a class of machines devised for the purpose of feeding sheet-paper automatically to any and all kinds ofmachinery wherein sheet-paper is used, as in ruling and calender-ing machines, printingpresses, 850. In fact, it is applicable in every case where sheet-paper is fed by hand.

The invention consists in combining with the regulating pressurefoot levers having an inclined or angular surface, by means of which the backward movement of the pawl is deter mined, as will hereinafter appear.

The invention also consists in combining an adjustable rubbing device and an adjustable holding device with a pivoted separating plate, which enables the machine to feed a greater variety of paper, as will hereinafter ap p ear.

The invention also consists in combining with the pivoted buckling devices a pivoted se iarating-plate having a horizontally-reciprocating movement, as will hereinafter appear.

The invention also consists in combining with the buckling devices a pivoted separating-plate having a reciprocating motion, and during the operation of separation an upward or downward movement, as will hereinafter appear.

The invention also consists in combining with the buckling devices and a paper'supporting table a separating-plate pivoted in vibrating arms, as will hereinafter appear.

The invention also consists in combining with the buckling devices and a table or support for paper a reciprocating pivoted separating-plate having thereon one or more frictional surfaces, which no operate with other frictional surfaces to remove a sheet from a pile of paper, as will hereinafter appear.

The invention further consists in combining (No model.)

Patented in England Apr HQ. 1881, No. 1,458.

an adjustable rubbing device with an adjustable holding device, bot-h working upon the surface of a paper sheet to lift the edge and separate it from a pile of paper upon the-table,

and the supporting-table, as will hereinafter appear.

The invention also consists in combining an adjustable pivoted reciprocating separatingplate, an adjustable reciprocating arm with frictional rubbing surface, an adjustable roll or holding device with a table or support for paper, and mechanism for moving said table automatically, as will hereinafter appear.

The invention further consists in a separating mechanism having a separating plate or bar and one or more rings or frictional surfaces which may be interposed beneath a sheet of a pile of paper and cooperating with africtional surface upon the other side thereof, by which the said sheet is separated and removed, as will hereinafter appear.

The invention also consists in the combination of a pivoted arm or toe with a movable.

plate or bar having a projection or inclined lug upon one side thereof, a spring or its equivalent, and a rod connecting with the belt or clutch-shifter, and placed in relation to each other and a part of the operating mechanism of the machine in such a manner that by the failure to interpose a sheet of paper between the pivoted arm or toe and the operative mechanism with which it may come in contact the machine is stopped, as will hereinafter appear.

Similar letters represent similar parts in all the views.

Figure 1, Sheet 1, is a view in elevation of the rear part of the machine. Fig. 2, Sheet 2, is a view in elevation of the left-hand side of the machine, showing the cam which operates the vertical screws used in moving the feed-table. Fig. 3, Sheet 3, is a view in section, as seen from the left-hand side of the machine, with the left-hand frame removed to show more plainly the cams that actuate the various levers and other operating mechanism. Fig. 4, Sheet 4, is another view in section with left-hand frame removed, showing the vertical screws which move the feed'table, the guide-plates, and friction-rolls, the feedtable with paper and paperguards, thebuckling device, and the cams which actuate the buckling device and separating-plate. Fig. 5,'Sheet 5, is a plan or top view of the machine, showing both sides of the frame, the feed-table with guards to hold the paper in place, the screws by which the table is moved, the ratchet-wheel and pawl for turning said screws, and the buckling devices, the taperolls with tapes, the regulating-roll upon movable arms which admit of its being raised from the paper or pressed thereupon when required, the registering plate or guide, and the driving and main shafts. Fig. 6, Sheet 6, represents a view of the rubbing and buckling device detached and enlarged to show more plainly the combination of the rubber and the roll each upon separate" arms, which in turn are pivoted to another pivoted arm having slots to admit of their adjustment, by which means the buckling device is made to press upon the paper with an unvarying pressure. The means of increasing or decreasing the pressure upon the rubbing-pad is also shown, also the rod or slide by which the buckling device is raised to permit a sheet to be withdrawn, and the relative positions of the different parts while the buckling device is buckling or arching a sheet of paper before the separating-plate is entirely withdrawn from its advanced position. Fig. 7, Sheet 7, represents the arrangement of levers in combination with a link, ratchet, screw, weighted pawl, the regulating pressure arm, which bears upon the surface of the paper and determines the distance which it shall be moved, the cams which actuate said levers, and the pin or stop having aninclined and the machine stopped whenever it fails to feed. Fig. 9, Sheet 6, shows the buckling de vice in the act of buckling or arching a sheet of paper preparatory to its removal, while the separating-plate is receding from its advanced position,having just discharged a sheet of paper, the bent arm by which the said blade or plate is held in a raised position, and the lever which, actuated by a cam, applies the pressure thereto, as will hereinafter appear.

A is the frame of the machine. B. is the feed-table or support for the paper, having a pile of sheets thereon, and is secured to nuts 0, which have extended arms a moving upon friction-rollers 0 1n recesses or grooves formed in or. on the frame, Figs. 1 and 4, and said nuts are actuated by the screws D, which aredriven simultaneously by the connecting-shafts D and the bevel-gears D.

E is the drivin g-shaft, upon which are placed the friction-wheels F, by which the sheet f paper is impelledforward when the smaller friction-rolls (1 Figs. 3 and 4, are mad t press the sheet of paper against them.

G, Fig. 2, is the main shaft, on which are placed the several cams that actuate the various arms or levers.

H is a sprocket-wheel on the shaft G, to which power is communicated by means of a chain,e,from a smaller sprocket-wheel, [,upon the driving-shaft E shown in Fig. 5.

J and J are tape-rolls, with grooves cut in each, the relative position of which is such as to carry the paper upon the tapes or cords passing from the feeder in a line diverging from a right line against the adjustable registering-guide K, which is fastened to thetapetable L by a bolt, a, Fig. 5, Sheet 5, which permits its position to be changed at will, the

"table being slotted at right angles with its length. The taperolls are revolved by means of a belt, 2, Figs. 2 and 5, passing around the roll J and grooved pulley 90 upon the main shaft G.

M, Figs. 2, 3, and 5, is a movable regulating-roll, having its hearings in one end of the arms N,the other end ofsaid arms being pinned to an independent shaft, 0, to which a reciprocating motion is imparted by means of the cam a Fig. 3, coming in contact with a cane roll on the end of a curved lever, Z1, which is also pinned to the shaft 0, as shown at Fig. 2, Sheet 2, and Fig. 3, Sheet 8. This roll is raised to permit the paperto pass without opposition over the tape-rolls J, and is then brought to bear against the surface of the paper, thereby regulating its forward motion, and imparting to it the same speed as the tapes, affording a better'opportunity for perfect registration.

P indicates guides to steady and direct the paper when fed from the pile or table to the tapes.

a", Figs. 3, 4, 5, and 6, is an arm to which the pressure-roll b is attached, and is used as aholding device during the operation of buckling. It is attached to the pivoted arm or lever S by the bolt or pivot d, the roll b being held upon the surface of the paper by its weight.

a is the arm which holds the rubbing-pad b and this, with the holding device consist ing of the arm a and roll N, forms the buckling device. It is also attached to the pivoted arm or leier S by the bolt or pivot d". Upon its upper side is secured a spring, f, which extends from the end on which the rubbing-padb is held toward the other end of the arm and past the bolt (1. Increased pressure of the pad 1) upon the paper is obtained by means of the thumbscrew c and a reduced pressure by the use of 0, both of whichare inserted in the arm a, and against the bot tom of which the spring is permitted to press, as the case may require.

The lever S is pivoted to the frame A at 1), Figs. 2, 3, and 4, by the stud y. Reciprocating motion is imparted through the cam-roll f 2 by the double-acting cam h and spring h. The other end of the lever Sis slotted, as at f, to admit of a variation of the distance between the roll b and rubbing-pad b. \Vith thick paper the distance should be increased, and per contra with very thin paper. W'ith heavy paper it is also necessary to apply increased pressure upon I)" by the thumbscrew e, and with very light paper to diminish it by the thumb-screw e to insure the separation of but one sheet. By pivoting the arms S, a, and a I am enabled to apply an unvarying pressure upon the surface of the paper.

Upon the inner side of the arm a is a lug or projectiomf (see Sheet 5, Fig. 5,) which extends under the arm (0, against which the rod or bar 2', Figs. 4 and 6, strikes when it becomes necessary to raise the buckling device i'rom the pile of paper to remove the sheet. The rod or bar z" is pivoted atj to an arm, R, working upon the shaft 1). It is slotted at i to permit its moving up and down, and is held in place by a stud screwed into the frame through the slot i. It is actuated by the ram 1) through the cain-roll 12 Fig. 3.

T is a horizontally-reciprocating separatingplate pivoted at d, Figs. 3, 4, and 5, to the two arms R which are pinned to the shaft 19, and it obtains a horizontal reciprocating motion by means of the arm R and cam 1-. It has also an upward and downward movement, which is obtained by the lever 0 being actuated by the cam r on the main shaft G, Fig. 4, and striking or coming in contact with the lever 0 of the separatingplate. The object of thisvertical motion is to enable the buckling device to fold or buckle the paper while the separating-blade is receding from its advanced position without pressing upon the fold of the paper and retarding the operation. It is also raised, when being advanced, to prevent the point of the blade from penetrating or disturbing the remaining sheets.

On'the shaft (Z are small rolls or frictional rings, which are brought in contact with the other side of the sheet of paper about being removed from the pile by the forward movement of the vibrating arms R, and pressing it firmly against the larger rolls F, which are constantly in motion. Motion being in this way communicated to them, they aid in delivering the sheet to the tapes.

At t is shown a slot or opening in the separating plate T, into which the pivoted toe m, attached to the sliding bar a of the stop-motion, falls when no paper is interposed between the toe and said plate to prevent it. The bar a is slotted at u, and on its upper side has an inclined or wedge-shaped projection, Fig. 3, Sheet 3. Upon being forced backward by the toe an engaging with the separating plate T the bar m in the slotted piece a is raised by the inclined surface of n, and disengaged from the shoulder r, Fig. 1, Sheet 1, which previously secured it, and by the pressure of the spring a it is forced outward,

throwing the lever m, Fig. 8, Sheet 7, far enough to disconnect the sections V and Vof the clutch, and thus stop the machine. The

slotted bar a, Fig. 3, when not forced from its position, is held in place by a spring, 10.

0 is an adjustable rod, upon which are placed the adjustable paper-guards c and can be lengthened or shortened at will by loosening the thumb-screw 9, Fig. 7, Sheet 7.

O is a disk, upon the under side of which is formed a ratchet, and is keyed to the upper end of one of the screws D, through which power is communicated to operate the feedtable.

S is a pawl,weighted at one end to keep the other continually engaged with the ratchet, and is pivoted by a stud upon the upper end of a rigl'it-angled lever, S, Fig. 7.

S is a right-angled lever, secured to the side of the frame A by the stud XV, upon which it oscillates, having at its lower end a cam-roll, K. It is actuated by the cam 0. Upon one side it has a projection, lug, or arm, one side of which is formed at an angle with a right line running vertically through the center of the stud upon which it is pivoted, as at x.

S" is another right-angled arm, secured to a shaft, 2, which extends entirely through the machine. At the end of the short arm it has a cam-roll, 0, through which motion is communicated by the cam 0". At its other end is pivoted a link, t, which is also pivoted at If to the horizontal bar V, Figs. 1 and 7, which extends through both sides of the frame. The other end of the bar U is pivoted to a link, it, and connection is made with the shaft 2 by means of a lever corresponding with the lever S without its short arm.

Y, Figs. 1 and 7, is a compensating or regulating lifting arm or feet, which is attached to the crossbar U by a screw near each side, one of which screws serves as a pivot. The other passes through a slot and permits the arm or foot to adjust itself to the unevenness of the surface of the paper. y, Figs. 2 and 7, is a pin in the lever S, which serves as a stop to determine the back ward motion of the lever S the position of which is determined by the position of the feed-table or pile of paper as the paper is taken from the surface of the pile. The arm or foot adjusts itself to the remaim ing paper, consequently the posit-ion of the long arm of the lever S is also regulated,permitting that part of the lever S below the pro jcction or lug a; to operate on the pin 1, and in consequence the pawl S engages a greater or less number of teeth in the ratchet of the disk 0 as the oscillation of the arm S is increased or diminished.

Z Z, Fig. 1, are plates, against which the front edge of the pile of paper is placed. A graduated scale, Q, is placed by the side of the feed-table or support for paper as a matter of convenience in adjusting the machine when a known quantity of paper is to be placed upon the feed table.

Having described the various pieces and parts of the machine, its operation is as follows: The pawl S is lowered,and the disk 0' is revolved in the direction of the slant of the teeth of the ratchet. Motion is thus imparted to the screws D,which engage with the nuts 0 and lower the table B attached thereto. The pile of paper is then placed upon said table, the front edge pressed against the guides, the right side of the paper being placed against other guides, to one of which the scale Q is attached, (shown in Fig. 1,) and by having straight edges upon two sides of the feed-table the paper can always be fed with accuracy. The disk is now revolved in the opposite direction until the top sheet of the pile of paper is even with the top-mark of the scale Q or the bottom of the compensating jor regulating arm or foot Y. The guards c are then shoved down behind the paper to prevent its being forced out of place by the action of the rubbing or buckling device. Should it become necessary on account of the width of the paper, the rod o Figs. 4 and 5, to which ithe :guards c are secured,may be pushed in or out to conform to the size of the paper, the rod c passing through a support, a, to which it is fastened when required by a thumb-screw. Power now being applied to the wheel of the drivingshaft IE, it is communicated to the main shaft G, upon which are placed the cams that actuate the various parts by the sprocket-wheels and chain. The rubbing or buckling device presses upon the surface of the paper, and with a reciprocating movement, which is preferably repeated two or more times to insure the separation of the sheet, rubs the sheet backward from the edge. of the pile and permits the blade T to press upon the remaining sheets or pile. Upon the receding of the buck ing device that part of the sheet which was arched by the rubber or frictional surface is drawn toward the edge of the pile, and not being permitted to occupy its former position on account of the presence of the separating-blade T it is forced upon the surface of said blade, which, by the operating mechanism, is now introduced further beneath the said sheet, the point having an upward movement as it advances to prevent penetrating the remaining paper in case there should be any unevenness of its surface, the reciprocating arms of the buckling device being raised by the upward movement of the rod 1', and the regulating arm or foot Y being raised by levers S and cam Z, Figs. 2 and 3. The separating-blade and the small rolls d continue to advance under the sheet until the rolls (I? approach sufficiently near to the large fricti onal rolls F,upon the shaft E,to press the sheet againstthem. Theybeingconstantlyin motion, cooperate with the smaller rolls to remove the sheet from the pileand deliver it on the tapes. The regulating arm or foot Y is now lowered upon the paper, and the separating blade or plate recedes with its point elevated to clear the next sheet, which is now being buckled or arched by the rubbing device, and is again pressed upon the pile of paper after a part of the sheet is removed from the edge of the pile, when the movements above described are repeated. The sheet previously removed is carried by the endless tapes on the rolls J J diagonally toward and against the side of the registering board or guide K, Figs. 2, 3, and 5, to its required destination. As the sheets are removed from the pile the regulating-roll M, which was previously raised to admit of the free passage of the paper, is lowered and impinges upon the paper, receiving its motion from contact with the tapes or the roll J. By this means the forward motion of the paper is regulated, and it is carried from the feeder at the same speed given to the tapes, which aids in obtaining a more perfect register of the paper.

The roll can be made to press upon the moving paper at any time by adjusting cam a which actuates it upon the main shaft G, it being secured thereto by a set-screw.

As the separated sheet is being removed from the pile the foot Y,which has been raised to allow the sheet to be drawn from beneath it,is now allowedto drop until it rests on top of the pile. If the top of the pile be higher than it should beas, for instance, in starting, if the table should be raised a little too high-the foot will not drop so low,and would also keep the projection Y of the lever S from dropping, and as the backward movement of lever S (to one end of which is secured the pawl S) is determined by the said projection coming in contact with it at x, and this determines the number of teeth the pawl shall engage in disk 0, so that in feeding paper of different thicknesses, the foot will drop a distance corresponding to the thickness of the paper removed, and the number of teeth the pawl shall engage in the disk shall be determined accordingly, and consequently by turning the screw D the feed-table is automatically raised to the proper position as the paper is fed off without regard to thickness.

It is is evident that a ratchet-clamp may be used with a smooth-grooved disk without teeth in lieu of the tooth-ratchet shown in the drawings with the same result. a In case of afailure or ommisson to pass a sheet of paper from the file or feed table the separating-plate T, moving forward, permits the pivoted point of the toe m to drop into or engage with said plate or blade T, Figs. 3 and 5, and being forced backward pushes the slotted bar a, and, by means of its upper wedgedshaped surface, raises the cross-bar m above its shou1der,when, by the pressure of a spring, w, it is forced outward, throwing the pivoted lever m in a position to disengage the sections V and Vof the clutch shown at Fig. 8, and stops the op eration of the machine.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
