,IMPROVEMENT IN PAPER-FEEDING MACHINES.

Specification forming part of vLetters Patent No. 143,740, dated October 2l, 1873; application filed Mayall, 1873.

To all whom 'it may concern:

Beit known that we, JOHN T. ASHLEY and FREDERICK ASHLEY, of Brooklyn, E. D., in the county of Kings and State of New York, have invented a new and Improved Paper- Feeding Machine; and we do hereby declare that the following is a full, clear, and eX- act description thereof, reference being had to the.'4 accompanying drawings making -part of this'specication, in which- Figure 1, Plate l, is an elevation of -one side of our improved feeder. Fig. 2, Plate 2, is a section taken vertically and longitudinally through thecenter of the feeder, as indicated by the dotted line w ab in Fig. 3. Fig. 3, Plate 3, is a top view of the feeder. Fig. 4, Plate 4,

isa section taken vertically and transversely thrbugh the feeder in theplane indicated by the"dottedline y yin Fig. 3. Fig. 5, Plate 4, is atop view of1th`e;movab le tray detached from the feeder. Figs. 6 and 7, Plate 4, are views of the upper and lower discharging del vices.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain novel improvements which are designed for picking up vsheets of paper from `a pile, one sheet at a' time, moving the sheets forward upon a feedboard, smoothing the sheets to a printingpress, ruling-machine, or to any other machine requiring to be fed with sheets of paper one sheet at a time. Our object is not only to pick up the sheets singly and deliver them in a proper manner to printing-presses and `other machinery, but also to so construct the feeder that the picking-up and feeding devices, as well as the supports for the pile of paper and the single sheets taken therefrom, are all adjustable and adaptable for sheets of different sizes, as will be hereinafter explained. i 1

Thefollowing description of4 our improvements will enable others skilled in the art to Vunderstand* it.

i In the accompanying drawings, A Ax represent the vertical and horizontal portions of the frame which support the pile-table A2,

tal rectangular table A2 which has vertical guides at its four corners, and which is connected to two vertical screws, g g, by means of brackets g1. This table A2 is for the purpose of supporting a tray, A1, on which is placed 'the pile of paper from which the sheets are fed; consequently it is necessary that the table should be slowly and regularly raised as the sheets are successively taken from the pile. To -this end I key on the lower end of each screw g a toothed wheel, g2, with which engages a worm-screw, g3, on a horizontal shaft, F,

as shown in Fig. 3. This shaft F has its bearings in the vertical cheeks of the frame, and

on one end of it is a ratchet-wheel, Fl, and a hand-crank, F2. Vith the ratchet-wheel engages'a pawl, f, which ispivoted to the ends of arms fl f2. The arm f2 vibrates freely on the shaft F, andthefarmfl is connected ec-v centrically by a wrist-pin to the face of achainl wheel, H, as shown in Fig. l. The wrist-pin 6 is secured to a slide, z, on the face .of the wheel H, by means of a set-screw, z', which, with gage-marks and a pointer, enables us to adjust for-raising the pile of paper more or less rapidly, according to the thickness of the sheets used in the feeder. The chain-wheel i H is keyed on one end of a horizontal transverse shaft, e, on the opposite end of which shaft is keyed a pulley, E2. (Shown in Figs. 2 and 3.) Around the wheel H passes an endless-chain belt, H1, which is ,carried along outside of the frames A' and K, and passed around another chain-wheel, H2, which is keyed on the shaft S of theimpression-cylinder S. The peripheries of the two chain-wheels are grooved and provided with lugs, which positively prevent the belt H1 from slipping. By these means motion isr transmitted positively from the shaft of the impression-cylinder S to the '.two screws vg g, which raise and depress the table A2, and the intermittent upward impulsesv given to this table can be accurately timed with respect to the movements of the said impression-cylinder. The upward movements given tothe table A2 must necessarily be regulated according to the thickness of the l sheets being fed, and the extent of these movements may be regulated by the movable wristpin 6, or by a suitable adjustment applied to the pawl-actuating devices. The hand-crank F2, above referred to, is for the purpose of rapidly running down the table A2v and adjusting it for piles of different heights, which can be done by disengaging the pawl f from the ratchet-wheelA F.

It will be seen that the mechanism which moves them is arranged outside of the frame A, which arrangement leaves the space beneath the table A2 free from the fly of the press and the iiying sheet, and also enables us to work the entire length of screws, which extend above the highest plane to which the table is moved. y

Al represents the tray in which the pile of paper is placed and properly adjusted. This tray, which is shown by lFig. 5 removed from the table A2, is a flat board having movable sides and back, within which the pile is placed. The front and rear edges of the board A1 are beveled, as shown in Fig. 2, and are embraced by clamps, to which setscrews 3 3 are applied. By loosening these set-screws', the side pieces a a can be adjusted transversely, and set at any desired distance apart. The side pieces a a are slotted longitudinally, which slots receive screws that rise through the horizontal portions of standards a3, and receive nuts a* on their upper ends. By loosening the nuts c, the standards a3 can be adjusted forward or backward. The two j\\baek standards a2 c2 are adjustably connected to a transverse slotted bar, al, which bar is itself adjustably connected to the slotted side pieces a a by means ot' screws and nuts w" a5. If desirable, the standards may be connected directly to the board A, which would be slotted for the purpose. vThis tray, it will be seen, is adjustablefor any-sized sheets of paper. It

serves a double purpose, to wit: It enables the' pressman to put into` the feeder a large number of sheets at one timewith great facility;

and it also saves loss of time in adjusting a pile of paper tothe center of the feeder, so as to insure a proper uniformity of margin after the sheets are printed. This nice adjustment could not well be' obtained if left to the eyerof the pressman; but with our movable tray the pressnian can quickly and accurately adjust a pile of paper of any given size into the tray, and then by simply sliding the tray over the table A2- until it abutsgagainst two stops, b b,

near the front end of the frame A, when it is known that the pile of paper is in its proper place. This desirable result is obtained by means of the adjustable standards b b, above described, and by having the tray fit snugly between the cheeks A A of theframe, asA

shown in Figs. 3 and 4. The stopsb b rise perpendicular-ly from a horizontal transverse bar, b1, which. -is slotted lengthwise, and through the slot pass two screws, having binding-nuts b2 on their upper ends for fixing the n stops .to the said b'ar b1, when they are' properly adjusted.

For the purpose of picking up the sheets of paper one at a time, and delivering them between discharging devices G E, picking-up devices are employed, which we will now describe: B represents a hollow trunk,- which extends transversely across the frame, and is supported upon springs s s between vertical guides J J', so as to lbe allowed to receive a vertical bodily movement. The guides J J f rise from longitudinally-reciprocating plates J, which rest on top of the cheeks A A of the frame, and are connected to these cheeks by means of pins o and slots o. (See Fig. l.) The plates J J receive longitudinal movements, carrying with them the trunk B, and each plate J is moved by means of the following contrivance: I represents a vibrating arm, which is pivoted at its lower end to a cheek, A, and e011- neeted to the plate J, at its upper end, by means of a pin and slot. On the shaft e is a segment-cam, (shown by dotted lines, Fig. 1,) which cam forces forward the upper end of arm I once during each revolution of the shaft e, thus moving forward the trunk. The spring s2, which is applied to each arm I, forces back the trunk. For the purpose of giving downward movements to the trunk, a vertically-movable hooked rod, nl, is employed on each side of the slot, a lever, n2. The curved arm of this lever is raised once during each revolution of the shaft e by means of a cam, @which movement brings down the trunk B. These parts are raised again by springs s and s1. Near each end of the trunk B an eye, nx, is secured to it, which receives a hook, n1,vwhen the trunk is moved back, as shown in Fig. l, after which the downward movement ofthe trimk takes place', as dejscribed. When the trunk is moved forward, the eyesn nx leave their hooks.

- per side, and two nozzles, u n, on its lower. side, near its extremities. To the nozzles n n ilexible hose is attached, which communicate with a suitable exhausting-engine. The nozzles d* for the purpose of allowing air to be exhausted from said fingers through the trunk B. There 5 are four lingers represented in the drawingto wit, two longitudinal side vn gers, C C. for picking up the sheets along their sides, and two intermediate fingers, C C, forpiclrin I up the sheets byV their front edges.

There maybe any desired number of ,intermediate ngers used, and for this reason I do not confine myself to any definite number. Each one of the lingers is a bellows-that is' to say, it is composed of two stift' boards connected together by some suitable flexible material. Each nger has perforations through vits bottom, for the purpose of allowing atmosup to said bottom when air is exhausted from the fingers. Each finger is secured to the trunk B by means of jaws and a clamp-screw,

the trunk. By these means the fingers can be adjusted for sheets of paper of different widths. When a sheet has been lifted from a pile of sheets and moved forward to the discharging devices G4 E, it is necessary to destroy the force ofthe exhaust at the moment the front feeder, which has 4connected to it, by a pin and y The trunk B has four nozzles, d", on its uplave iiexible hose d d attached to them, whichl are attached to nozzles on picking-up fingers,

pheric pressure from without to hold the sheets r', which jaws and screw take over ribs r 1' on:

v .edge ofthe sheet is received in the bite of said devices. To this end I employ a valve, c', for an opening, c, through the trunk B. The long stem of this valve is pivoted to the trunk, and its extremity is turned up so as to be alternately struck by two fixed stops, Bf B', rising from the cheeks A A, as shown in Fig. l. The front stop is arranged so as to open the valve c at the moment the paper is taken hold of by the dischargerollers, and the rear stop is arranged to shut the valve c, when the trunk reaches the end of ts'back stroke, as shown in Figs. l and 3.

rlhe roller E receives rotation from pulley E2 by means of a belt which passes around this pulley, and also around a pulley, E1, on one end of this roller, as shown in Fig. 3. The highest point of this roller E is in, or nearly in, the plane. of a sheet of paper when carried up to it so that the ont ends of the fingers C C can pass freely over said roller and between the devices G.

If desired, a flat xed surface may be substituted for the rolling surface E; but for many purposes I prefer the single roller, or a number of small rollers. y

Thetop discharging devices or rolling dischargers G( are secured to and are adjustable on a shaft, G. Each. one of these dischargers G consists of two circular plates, having a circular piece of india-rubber, cloth, or other suitable flexible material, i', secured between them.

\ It is desirableto have the material t' directed outward, as shown in the drawings, as in this case it will not only assist the roller E in moving the sheets forward, but it will also spread the sheets smoothly laterally on the roller E. For readily and accurately applying the materiali between its clamps 7L la', I form around the hole which is centrally through the concave clamp.

h a short hub, 3, corresponding exactly to Y the hole' which is made centrally through the material t'. I also forni a circular central depression into the convex face of the clamp i, corresponding in diameter to the hub 3. The material is then fitted over the hub 3, and thus centered with respect to the clamp 7L. The two clamps h hf are then conned together by screws, and it is known that the material is in the center of them.

WVe find it best to have the material as thin as possible, so as to be able to run on the narrowest margin that may be required 5 also, to have the material c' bear upon the sheets a-s lightly as possible, just enough to hold them upon the roller E. The sheets are thus allowed freedom to run laterally, either `to the right or left, between two side guides, L1 L1, of a feed-board, L, and thereby facilitate the act of drawing` each sheet to the required side guide. v L

This feature of our invention is a very important one, as the sheets 4are allowed perfect freedom to run onto the feed-board prepara tory to being acted on .by the registering devices. The feerLboard L is directed downwardly from the discharge-rollers to a point which is near the impression-cylinder S, as shown in Fig. 2, Plate 2, and, by narrow continuations or guide rests w w, the front sides of the sheets are supported while beingmoved from the feedfboard proper to gripers on the impression-cylinder S. Our feed-board consists of transverse bars m1 m1 m1, two of which are slotted longitudinally, and longitudinal corrugated or ribbed strips m m m. rlhe strips m are secured to the two slotted bars m1 m1bymeans of screws m2, (shown in Fig. 2, Plate 2,) which allow the strips m to be adjusted laterally, and held at any desired distance apart. At each side of this feed-board is a guide, L1, consisting of a bottom, a top, and a side, which latter is exactly at right angles to the longitudinal axis of theimpression-cylinder S. The highest end of each guide L1 is flaring, so as to receive under it with certainty the front edge of every sheet of paper which is discharged by the devices E G. The side guides L1 L1 are adjust able laterally on the feed-board for sheets of paper of different widths, hence the necessity of making the surface of the feed-board between these guides of adjustable sections.

As the sheets leave the discharging devices they may be more or less out of a straight line, and it is therefore necessary to adjust them on the feed-board preparatory to their bein taken by the gripersof the press. Ve accomplish this by drawing one side of each sheet against one of the side guides L1, and almost simultane ously by drawing the front edge of the sheet to the guides of the press. For this purpose we employ revolving fingers t t1, which are composed of narrow strips of rubber or other flexible frctional substance, secured to clamps t2, which are adjustably applied on their respective shafts N M. The iinger t is applied on a longitudinal shaft, N, whose bearings are lin brackets L2. The brackets L2`aie secured on top of each guide L1 in such position relatively to its inner edge that the finger t, in revolving, will impinge on the margin of a sheet of paper, and move the edge of this margin up laterally against the straight longitudinal edge of the guide L. The shaft N receives its rotation from the horizontal transverse shaft M by means of bevel -wheels p p. The feedboard is pivoted at its upper end to the cheeks A A, and supported at its lower end on frame K by means of bracket L3 and adjustingscrews Z.

municated from a chain -wheel on the shaft S v of the impression-cylinder by means of a chainband, 2. The two chain-wheels and the chainband are constructed like the chain-band II and wheels H1 H2, so that the band cannot The lower end of the feed-board is, by these means, adjustable vertically for setslip. On the shaft M are adjustably applied two registering-anges, t1 t1, which are constructed like the registering nger t, and arranged to work over the surfaces of the guiderests w w, for the purpose of drawing the sheets forward against the guides of the press, so as to deliver the front edge of each sheet properly to gripers on the impressioncylinder S. These fingers, and also their guide-rests w w, are laterally adjustable for sheets of different widths.

In carrying out my invention, above described, I desire to have the trunk B remain at rest for a short period of time when in a depressed position, for the purpose of insuring the proper taking hold of the sheets before the trunk rises.

Forthe purpose of printing both sides of a sheet .we employ the two side guides Ll L1, one of which is used in passing the sheet over the feed-board the first time; then, after turning over the sheets, the iother guide is used. A finger-carrying shaft, N, is applied in the bearings L2 on bothguides, and the bevelwheels p on the shaft M, which rotate the said shaft N, are adjustable, so that either one of these shafts the finger on which it is not required to use can be thrown out of gear, and its motion stopped; or, if desired, only one finger-carrying shaft, N, may be used, and

- this shaft changed from one pair of bearings,

L2, to the other pair, whichever guide it is desired to use.

The paper is placed in the tray A1, which has previously had its side and back strips adjusted to the size thereof. The tray with the paper is then run into the part A of the f frame upon bed A2. The machine is then set in motion through the shaft S', when the picking-up fingers become exhausted of atmospheric air by means of a suitable exhausting-en gine, connected by suitable iiexible pipes with the nozzles of the trunk B. This causes the fingers to pick up the topmost sheet of paper from the pile on the table, and to hold it until carried, by a movement imparted to the trunk by the cam e, to the roller E and dischargers t', whereupon the sheet of paper is forced down upon the feed-board L until brought under the side-registering device t,

which draws it over to the side guide L1. The sheet having been drawn to that side, the next moment it is acted upon by the frontregistering devices tl, and is then ready to be taken hold of by the gripers of the cylinder S of the printing-press, and carried properly to the printing-form. While this operation is proceeding the elevating-screws gg are turned suiiiciently, bythe agency of the endless chain H1, pawl and ratchet-wheel, and wormgearing, to cause the table-bed, with the table and paper, to rise a distance equal to the thickness of a single sheet of paper. When this is accomplished the picking-up fingers are again exhausted, and caused to pick up the next toprnost sheet of the pile, and carry it forward in the same manner as the first sheet was carried, and thus the operation continues until all the paper isfed' out of the machine.

Having described our invention, what we claim as new, and desire to secure by LettersV Patent, is-

1. Picking-up fingers adjustably appliedto and combined with a'movable trunk, 13,substantially as described.
