SPECIFICATION forming part of Letters Patent No. 367,489jdated August 2, 1887.

Application filed April H3, 1886. Serial No. 19!),l5l. (No model.)

To all whom it may concern..-

Be it known that I, NEWEL B. WOOD, of Vashington Court-House, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Apparatus for Baling and Binding Straw, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in thea-rt to which it appertains to make and use the same.

My invention relates to that class of machines which are designed to compress straw, hay, and similar materials into the form of bales, and to secure the same after such compression by means of cords or wires for preserving the form of the bales.

The objects of my invention are to produce a machine which shall operate continuously in compressing, binding, and delivering the ma.- terial, and fastening the binders or wires for preserving the forms of the bales; also, to ma terially increase the capacity of this class of machines,and to render them more durablein construction and certain in operation.

To these endsmy invention consists, first, in a peculiar and novel construction and arrangement of devices for conveying the straw or other material from the source of supply to the compressioil-chamber, as hereinafter described and claimed.

My invention further consists in certain novel means for severing the mass in front of the COIIIPIGSSlOll-hitd from that in the conveyor, whereby all choking of the machine and irregularities in the supply are avoided, as also hereinafter described and claimed.

My invention further consists in a certain peculiar and novel arrangement of connections, whereby the movements of the compressor-head are caused to actuate the devices for laying and fastening the binding wires or cords at suitable intervals, as hereinafter described and claimed.

My invention still further consists in eertain peculiar and novel devices for laying the wiresor cords around the bales, for fastening such wires or cords, and for severing the wire or cord supply from the fastened wires or cords without disconnecting the supply from the wiring or cording devices or interrupting the action of the latter, as hereinafter described and claimed.

My invention further consists in the peculiar and novel arrangement of the compression wiring and cording mechanisms,whereby the bale is partially compressed against the resistance of the binding wires or cords, as hereinafter described and claimed.

Finally, my invention consists in certain peculiar and novel details of general construction and arran ement, as hereinafterdescribed and claimed.

In order that myinvention may be fnllyunderstood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure 1 is a side elevation of my improved machine. Fig. 1 is a detailed view showing wire guides or threading-frames- Fig. 2 is a longitudinal vertical section on line 3 3 of Fig. 3. Fig. 3 is a plan View on line 1 1 of Fig. 1 of lower part of the maehine,partly in section. Fig. 4 is an enlarged vertical section on line 2 2 of Fig. 2, showing the angular packers. Fig. 5 is an enlarged plan view of the front portion of the machine. Fig. 6 isa detached view of latch i Fig.7 is an enlarged side elevation of the forward end of the machine. Fig. 8 is a diagrammatical view of the gage-wheel regulating the size of bale. Fig. 9 is a detached view of book in engagement with the cross-head. Fig. 10 is a similar view of the hook in position to recover its normal adjustment. Fig. 11 is an enlarged vertical section through the baling, knotting, and threading mechanisms. view of the knotting mechanism. Fig. 13 is a view in perspective of the knotter, showing by dotted lines the normal position of the top wire while at rest, and in full lines its position when in the path of the knotter-h0oks. Fig. 14 is adetail of supportingplate for knotter. Fig. 15 is a side elevation of twister. Fig. 16 is a cross-section of same.

In the said drawings, Adesiguatcs the body of the machine, which is of oblong rectangular form, and which may be mounted upon trucks ]3 or other suitable supportinggears, as de sired.

C designates a crank-shat t, which i s mounted 100 Fig. 12 is a plan horizontally in the rear end of the box A, and which is also formed with two crank-arms, c c, as shown, for a purpose to be hereinafter described. Midway of its length this shaft 0 carries a gear-wheel, c, the teeth of which mesh with those of a pinion, (Z, upon a powershaft, D, which is mounted horizontally in standards (2 upon the body A, as shown. These shafts O D extend transversely of the body A, and the shaft D lies above and beyond the shaft 0, as will be seen by reference to the drawings. Upon one end of the shaft D is mountcd'a sprocket-wheel, d which receives power from anysuitable motor through a belt or chain running over its periphery. Upon the opposite end of. this shaft D are mounted sprocket-pulleys d" d, for a purpose to be hereinafter described.

E E designate vertical standards, which are arranged at each side of the body A contiguous to its feed-opening a, as shown. The standards E E are bent first upwardly toward each other, and finally outward away from each other, so that the space between these four standards is widest atthe top, diminishing downward to a certain distance, then expanding in width downward to the feed-opening a. This peculiar form of the standards E E possesses important functions, as will be seen from the ensuing description. In the upper extremities of the standards E E is mounted a horizontal shaft, F, which carries a band or chain wheel, f, over which the chain or belt f from pulleys d passes. Shaft F also carries a gear-wheel, f located at the side of band or chain wheel f, the teeth of which mesh with those of an idle gear-wheel, 9, running upon a shaft, G,which is mounted horizontally in the rear standards, E, below the shaft F. This shaft G also carries a band or chain wheel, g, from which a band or chain, g", runs to a pulley, 71, upon a shaft, H, which is mounted horizontally in the upper extremities of the front standards, E E. It willthus be seen that the two wheelsf g revolve toward each other. Mounted on the shafts F H are rollers, which actuate the endless belts I, these belts being of canvas or other suitable material and provided with transverse slats i, which, by the motion of the belts, tend to force the straw downward into the feedopening a. A series of similar rollers, 6, preferably two at the rear and three in front, are journaled in the standards E E at a lower position, these being adapted to guide the belts I. This feeding action is also assisted by roll a so that a constant supply of straw is conveyed downward toward the feed-opening a. The

passage of straw or other material between the belts I is still further aided by a series of obliquely mounted needles or packers, g, which are mounted upon crank-sections g of the two downwardlyslanting shafts G, operated by the shaft G", so that as the shafts G revolve the fingers or packers 91 will alternately enter the straw and draw it downward and apart toward the sides of the compression chamber and evenly distribute it therein. Links are pivoted at one end to frame A, and the opposite ends of said links are pivoted to the lower ends of the packers 9 whereby the said links serve to insure the proper action of the packers. This arrangement of packers g", and also of the idler g and gearwheel f may be duplicated upon this and opposite standards E E, as desired.

Upon the rear standards, E, is mounted a band or chain wheel, K, over which runs a belt or chain, It, from the belt or chain pulley (1, upon the power-shaft D. A belt, Z, runs from the periphery of belt or chain wheel K, beneath wheel Z and over wheel Z, thence to aloose beltor chain wheel, Z, which is mounted upon a horizontal shaft, L, extending partially across the body A. This shaft L carries a suitable number of bevel-gears, Z", which serve to transmit power to the knotting mechanism, to be hereinafter described.

\Vithin the body or box A is located the reciprocating traverser M, which is of such size as to fill the interior of said box or body. At its rear face this traverser is suitably coupled to two rods, m, by means of a cross-head and straps, which are in turn connected at their rear ends with the cranks 0 c of the shaft 0, so that as said shaft revolves it will reciprocate the traverser llI longitudinally of the body A, and the rods m serve not only to actuate the traverser but also to guide its movement in the body A.

It will be readily seen that the motion of all the above-described parts is continuous, irrespeetive of the periodical movements of the tying, threading, and other mechanisms yet to be described, these latter parts being automatically thrown in and out of action by the movement of the bales through the press.

Rigidly attached to the traverser M is the cross head M,proj ecting through and working in two slots, a, formed longitudinally in the vertical sides of body A. Upon the upper front edge of the traverser M is located a knife. m which may have either a plain or serrated cuttingedge, and which works in conjunction with a similar knife, m, secured to the front transverse edge of the feed-opening a.

If desired, the knife in may be dispensed with, and a series of fingers or guards, m may be substituted therefor, said guards m serving to convey the straw or other material, and hold it in position while being severed by knife m By virtue of this arrangement of the knives or guards the forward movements of the crosshead M are caused to sever that portion of the straw or other material which lies within the body A in front of the cross-head from that which remains in the throat above the feed opening, and in order to facilitate the action of these knives or guards the cutting-edge of knife m is set obliquely, so as to operate upon the knife in or guards m with a shearing cut. It should also be stated that the depth of the traverser M is such that it closes the feed opening during its forward movement,in order to prevent the entrance of any more straw into the body A until the traverser has traveled backward again. The purpose of widening the lower extremity of the feeding-throat will also be perceived at this stage of the descrip tion, as it enables the feeding devices to accumulate a supply of straw, while the traverser closes the feed-opening, so that when the cross-head has been drawn backward the accumulated supply of straw will be carried into the body A, and thus no cessation of the feed will occur.

At each side of the body A is mounted a gear segment or quadrant, N,which is pivoted at n to the body. Teeth n of these quadrants are at the lower extremities of the same, and each set of teeth mesh with those of a gearpinion, 0, mounted rigidly upon a shaft, 0, extending transversely beneath the body A. This shaft carries two pinions, 0, one at each end, and there are two segments, N, one at each side of the body A. Upon the shaft 0 are rigidly mounted a series of threadingframes, P, corresponding in number with the wires or cords for binding the bales. Each of these threading-frames is of segmental form and works upward through longitudinal slots (6 in the bottom of the body and a similar slot, to, in the top of the said body. Three of these threading frames are generally employed, and the upper and lower slots, a a,

correspond in number with said frames. The cords or wires for supplying these frames are supplied from two reels or spools, 0 0", placed, respectively, below and above the body A, as shown. The wires or cords from spools 0 pass over and under tension-sheaves 0", thence over and under guidingsheaves p p 11 upon the frames 1? to the tips 19 of said frames, and said wires pass through the slots a from the tips 1), and their ends are fastened to the ends of the wires or cords from the upper spools, 0 The wire, which is drawn upward around the bale by the threading-frame P, is guided in its direction by sheaves 0 The number of reels or spools and tension devices correspond with the number of threading frames, and said spools are mounted, respectively, upon an upper spool-shaft, 0 and a lower spool-shaft, 0.

From the foregoing description it will be seen that the threadingframes are actuated by oscillations of their shaft 0, which is actuated in turn by oscillations of thepivoted seg' ments N.

It will be seen that the threading-frames P serve to take up the rebound of the bales through the middle portion and hold the latter while being bound, while the springactnated hooks T prevent the rebound of the straw at the edges of the bale. These hooks are so formed with beveled ends 26 that the traverser forces them back out of the way as the hay passes, the hooks immediately springing into their normal position by dropping into slots S. of the traverser. The oscillations of these segments are produced by two bars, Q, each of which is pivoted at q to the small end of the corresponding segment. ends these bars are each formed with a downwardly-extending hook, g, which, as the bars Q lie outside of the body A, engage at times with the extensions m of the cross'head or compressorM. Thisengagement of thehooked bars Q occurs during the backward stroke of the crosshead, and hence it will be seen that the upper parts of segments N will be carried backward and produce a forward movement of the lower parts of said segments. As the results of this movement, the threading-frames P will be raised into the body'A, and as the cross-head M moves forward it will reverse the stroke of the segment N by the cross'head coming into contact with pivoted arm a, which is connected therewith by rod U, and thereby withdrawing the threading-frames P, and the mass of straw will impinge against the joined upper and lower wires which the threadingframes leave in position for the new supply of straw which draws them outward toward the forward or discharged end of body A. Thus the wires are caused to embrace the mass of straw and assist in its compression into the form of a bale. The bars Q extend forward beyond their point of pivotal attachment to the segment N, and at their forward ends said bars are provided with vertical bars R, these At their rear being connected at the top by a crossbar, Q,

as shown. A shaft, S, extends horizontally across the body A, and carries two wheels, 8, which are toothed or serrated upon their peripheries, and which extend through slots 00 in the body A. The toothed or serrated peripheries of these wheels extend down into the compression chamber of body A, and are rotated by contact with the forwardly-moving mass of straw therein, so that the shaft S is rotated thereby in the direction indicated by arrows. This shaft S also carries a looselymounted ratchet-disk, s, midway between wheels 8, the teeth upon the periphery of which incline toward the front end of the machine. A pawl, s pivoted upon this disk, engages the teeth of a small disk, 8, rigidly ITO secured to the shaft S, the said teeth being in clined oppositely to the teeth-disk s. The disk 8' also carries one or more tripping-pins s, which engage the lower end ofa pawl-rod, T, which is pivoted upon an upright arm, t, resting upon the top of the body A. The size of the bale is regulated by the position of these tripping-pins, the number of bales per rotation of the disk 8 corresponding with the number of equally-separated trippingpins located thereon. The rod T is pressed forward at its lower end by a spring, t, so that its lower end engages with the pins 8 of the disk 5', and its upper end, which has a hook, 8 engages the horizontal bar Q. It

segments N and threading-frames P, as before described. In so doing the hook g, which is provided with the inwardly-projecting pin slides beneath the pivoted incline g, which latter, acting as a gravity-latch, immediately drops on being released by pin q. It will then form an incline surface upon which pin will ascend as the traverser M moves forward, releasing the hook q from the crosshead M, allowing the horizontal bars Q again to be engaged by the hooked end of the rod T, by which it is held until sufficient hay or straw has been delivered to form another bale, when the bar Q is automatically released and the operation repeated. The disengagement of bar Q is owing to the action of the trippingpins upon disk 8 relative to the pawl-rod T, throwing the lower end of the same rearward. As the bar Q rises and moves backward, its hook q engaging the teeth of wheel 8, accelcrates the motion of disk or wheels s,thereby clearing the path of lower end of rod T, so as to permit said rod T to resume itsnormal position and allow the upper end of the pawl-rod to move into position 'to receive the bar Q by its hooked end .9 .Vhen the hooked ends of bars Q have ridden up over the inclined guides upon their return movement, which they do as the traverser moves forward, the bar Q is engaged with the hooked end of pawl-rod T, and the disengagement of the bar Q and pawl-rod T may be repeated. During the forward movementof the traverser its cross-head extensions m come in contact with arms a, extending upward from and pivoted atthe lower end to arms U, which are in turn pivoted at their forward ends to the segments-N at u and return the said segments to their normal position,throwing the threading-frames B down out of the path of the traverser, as shown in Fig. 1.

The shaft L, before described, is provided at one of its ends with clutches Z Z, the engagement or disengagement of which throws the wire-twisting mechanism respectively in or out of motion. The free end of lever Z", which oscillates the movable clutch Z", is normally held outward, as shown in Fig. 5, by the spiral spring Z,- but as the crossbar Qmoves forward to be engaged by the hooked end of the pivoted pawl-rod T, the link t which is loosely buckled to the arm t, gives the cam i a turn which forces the free end of lever Z, carrying clutch Z inward, where it is held by the latch it, which immediately engages it. The clutches Z Z are held in this disengagement until the backward movement of crossbar Q takes place, when the latch 25 is liberated from its engagement with the lever 1? by the camsurface Z", secured to one of the arms Q, as shown in Fig. 7, sliding beneath its free end, lifting it and allowing the spring Z to force the clutches together.

The beveled gears Z mesh with similar gears, 12, upon vertical shafts V. Loosely mounted upon the lower end of shafts V are the rearwardly-projecting plates 12, which are provided with the peculiar-shaped slots ofielearl y shown in Figs. 12, 13, and 14. The said slots serve a double purpose, the outer portion acting as a guide for the binding-wires,while the inner rounded portion, a, carries the twister v The twister e is provided with teeth on its periphery, which mesh with similar parts on the large wheel V, mounted on the lower end of its vertical driving shaft V. The twister e is also slotted and provided with the opposite V-shaped ribs 12", which are located near enough to each other to prevent more than one wire entering the middle of the twister at a time, and while twisting the sharpened edge w pierces and severs the wires. Beneath the twister if still another guide-plate, e, is located, the same being so constructed, with the projecting finger 178, as to hold the upper and lower wires rigidly until the grabbing-hooks e located above and below the teeth on twister c, which project beyond the periphery of the twister alongside of the slot or opening therein, come in contact with the wires, removing them from the fingers v whence, owing to the position of threadingfrarne P, having its points 1) respectively above and below the middle of the twister a, as shown in Fig. 2, the wires slide one after the other between the ribs e, and become weakened at that point by the rapid rotation of said twister as the wires are being twisted. After the wires have been sufficiently twisted and the surplus wire between the said points pip" have been taken into the twist, the resistance becomes great enough to sever the wires at the weak point at rib 12, thus finishing the tie on the bale just formed and leaving the corresponding wire ends with a duplicate knot for the next bale, as previously described.

The front end of the body A is opened, and near this opened end, at the vertical sides of the body, are located two swinging sections, X, hinged at their rear or inner ends to the body and adjusted inwardly and outward by setscrews 00, as shown.

The swinging sections afford additional lateral pressure'to' the mass'of straw' and assist the cross-head in compressing the same. Said sections may be set farther inward at the be ginning of the operation of the machine and may be drawn outward when the machine has been operated for a short time, so as to decrease the lateral pressure. from the machine by one or more bales succeeding it through the compression-chamber.

The straw is first thrown into thehopper, and is carried by the belts I down into the restricted throatof said hopper, at which point it comes within reach of the packers gflwhich latter force it into the compression-chamber. The movement of the completed bales regulate or control the movements of the threading-frames, and when sufficient straw to form a bale has been packed within the compression-chamber the- Each bale is discharged of bars Q, to drop into a position to engage the cross-head M. This engagement of the bars with the cross-head M elevates the threadng-frames 1?, which latter carry the wire up 5 into a position to beengaged by the twister, wh chis now operating. This twister twists and severs the wire and at the same time u nites the ends of the wires leading fromthe upper and lower reels, as shown in Fig. 1. On the return movementof the cross-head the latter engages the lever 10, which, through the intervention of the .rods U and segments N, withdraws the threading-frames from the compression-ehamber. The rearward movement of 1 the eross'head or compressor opens the lower end of the throat of the hopper or permits the straw therein to be forced into the compression-chamber, where it is acted upon by the 1 compressor until sufficient quantity has been packed therein to form another bale, when the bars Qare again tripped and the binding opera tion repeated. y
