SPECIFICATION forming part of Letters Patent No. 593,148, dated November 2, 1897.

Application filed March 26, 1897 Serial No. 629,409- (No model.)

To (LZZ whom it may concern.-

Be it known that I, NORMAN B. WILDER, a citizen of the United States,residing at Prophetstown, in the county of Nhiteside and State of Illinois, have invented certain new and useful Improvements in Baling-Presses; 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 the art to which it appertains to make and use the same.

This invention relates to certain improvements in baling-presses and powers therefor.

The object of the invention is to provide certain improvements in rebounding-plunger baling-presses whereby a most durable, simple, powerful, and eflicient baling-press will be provided, composed of a minimum numher of parts for the purposes intended and results to be attained.

A further object of the invention is to provide certain improvements in powers for rebounding-plunger baling-presses, which will be simple and durable in construction and composed of a minimum number of parts.

The invention consists in certain novel features in construction and in combinations and in arrangements of parts, as more fully and particularly pointed out and described hereinafter.

Referring to the accompanying drawings, Figure 1 is a side elevation of the press provided at its front end with the power to which a steam or other engine is coupled. Fig. 2 is an end view thereof. Fig. 3 is a longitudinal central sectional view of the press of Figs. 1 and 2. Fig. at is a top plan view of the press of Fig. 1. Fig. 5 is adetail perspective View showing the bed-beams and various parts which are coupled thereto detached and separated. Fig. 6 is a detail cross sectional view taken through the frontsupporting-axle, showing the front ends of the bed-beams and the king-bolt and the manner of coupling the lower end thereof to the axle. Fig. 7 is a detail top plan of the bed-beams, the frame and parts of the machine being removed on the section-line 7 7, Fig. 1. Fig. Sis a detail perspective view of the sheave to which the plunger-operating cable is attached, showing the sheave-actuating trip rigid withthe shaft of the sheave. Fig. 9 is a detail view, partly in section, of the joint in the presser-headoperating toggle. Fig. 10 is a detail diagrammatical view of the mechanism for controlling the trip-shaft and throwing the trip out of the path of the trip-operating projection.

The frame of Y the baling-press generally comprises four parallel bars a, arranged horizontally and a suitable distance apart to form what might be termed a rectangular foursided structure. These bars are connected by suitable cross-frames, while an intermediate portion of the frame is inclosed or otherwise suitably formed to constitute a balingchamber 5 of any suitable or desirable structure, which in itself forms no part of my present invention. The baling-chamber terminates rearwardly in the open slideway between the upper and lower bars of the frame, where the division-boards (not here shown) can be introduced and the proper bale-ties inserted. The rear ends of the beams are united by the pressure-applying device 0, of any suitable construction, forming no part of my present invention, the completed bales being discharged, as usual, between the rear ends of the bars, the hay being compressed in the baling-chamber and forced therefrom along between the bars a in rear of the chamher, where suitable pressure is applied thereto by drawing the ends of the bars toward each other by the pressure device 0.

a are the retainingdevices, of any suitable construction,extending through the side walls of the baling-chamber to perform their well known function in preventing retrograde movement of the hay after being compressed by the plunger hereinafter referred to.

The baling-chamber has the top feedingopening Z1, which can be provided with any suitable hopper or table for carrying the hay being passed into the feeding-opening, the sides or a portion of the hopper or table being shown in Fig. 4 and lettered (4 The frame comprising the said longitudinal bars a extends forwardly a suitable distance in advance of the baling-chamber to carry the plunger-operating means, and the front end receives and is rigidly secured to an end head or frame d, arranged vertically and provided with the depending lug or projection cl for the purpose hereinafter referred to.

e is the reciprocating presser or plunger head, preferably mounted and traveling on the antifriction-rolls 6, running on a suitable track or guideway formed by the floor of the paling-chamber and the frame in advance thereof. The plunger head reciprocates through or partially through the baling-chamher, as usual, and is preferably recessed at its rear to receive the front end of the operating toggle or pitman pivotally joined to the head in said recess. The lower portion of the rear side of the head is provided with the two rearwardly-extendin g beveled or tapered projections e which on the rebound of the plunger engage the curved cushioning-springs ff to cushion or break the force of the rebound of the head. These springs are at their rear ends secured to the lowerportion of the frame, with their curved free ends extending forwardly over the rigid stops g g and beyond the same into the path traveled bysaid curved projections or surfaces 6 of the head, so that when the head rebounds said curved surfaces engage said springs and force the same up against the tension thereof before said projections finally engage the rigid stops g 9 formed in the frame, which positively limit the rearward throw of said head.

The presser-hea d-o perating toggle or pitman comprises thelonglink h, atone end pivoted to the presser-head, as before described, and the shorter link 7t, at one end pivoted to the forward end of the link it and at its opposite end pivoted to a rigid part of the frame of the machine at a point preferably below the horizontal plane in which the head reciprocates and in a manner hereinafter set forth. The shorter link 7i is preferably composed of two parallel plates or bars arranged on opposite sides of the front end of the link h and confined thereto by a single pivot-pin 712, which also passes through a recess 7L3, extending completely through the end of the link It, and in which a loose pulley h is arranged and mounted on the pivoted pin 71 so that the pulley rotates in a vertical plane on the horizontal pivot-pin. The link h has the lateral bosses 7r rigid therewith,on which the ends of the bars forming link 72, turn and are confined by the nut and head of the bolt 7L2 and suitable washers.

t7; are a pair of parallel horizontal strongly and usually similarly constructed bed-beams arranged parallel with and beneath the front portions of the lower frame-bars a, and usually, although not necessarily, extending from the front end of the frame rearwardl y to a point beneath the front end of the balingchamber. However I do not wish to limit myself to this precise relative length and exact arrangcment of these bed-beams. These beams are strongly and rigidly secured to the under side of the frame-bars a at the front end by having their front ends 2" separated a suitable distance and arranged on opposite sides of the lug d of the end head of the frame and secured thereto by the cross-pin or bolt passed through said ends of the bed-beams and the said lug. The rear ends of the said bed-beams have the transverse grooves or seats 1' in their upper and lower faces, and the lower cross-head 7;", extends transversely across the under sides of the rear ends of the said bed-beams and fits in the under crossgrooves thereof and has the raised ends at the outer sides of the beams forming the vertical shoulders 70, fitting the outer edges of the beams and thereby locking the beams to gether against separating movement. The upper cross-head Z fits in the upper crossgrooves of the beams and extends trans verselyacross said beams and at its ends rests on the. extended ends of the under cross-head 7c and is provided with the upwardly-extending lugs or cars Z, engaging the sides of the frame of the press and thereby holding the two bed-beams against lateral play independent of the press-frame bars. The vertical tie-bolts m pass up through the projecting ends of the two cross-heads kl and along the outside of the baling-chamber and through a cross-head n on top of the baling-chamber,

where the tie-bolts are provided with securing-nuts or other suitable and desirable lock ing means. The front ends of the bed-beams are thus rigidly secured to the front head of. the frame, while the rear ends of the beams are also rigidly and stronglysecured and confined to the under side of the frame-bars and also are secured together by the same means. These bed -beams are secured rigidly one against the other and are recessed at their A inner faces to leave ample room and space for the free movement of the link 7L of the toggle.

Just in advance of the cross-heads 7t Z the inner faces of the two beams are recessed to form a space for the pulley 0, which turns in a Vertical plane on the cross-bolt 0, also assisting in securing the bed-beams together.

At the front end of the long central opening between the bed-beams and at their inner faces said beams have the longitudinally slotted or bifurcated portions 1; 71 which fit to gether or engage each other so that their longitudinal slots 2' coincide. These slots open through the rear ends of said portions into I the central space between the beams and at their rear ends terminate in the shoulders f, and the slotted portions 2' are separated from the bodies or main parts of the beams by the vertical spaces or recesses 2'.

p is a bearing-block arranged in the front end of the space between the two bed-beams, with the two bosses p 19 extending laterally from the opposite side edges thereof to the inner faces of the two bed-beams. The lower ends of the two bars forming the link h of the toggle have bearing-openings confined and turning on said bosses, and a bolt or pin q is passed transversely through the bed beams and through the bearing-block, passing centrally through said bosses. The bearing-block is provided with a forwardly-projecting shank p extending into the slots 2 from the front end thereof and fitting snugly therein and at its rear end abutting against the shoulder 11 at the inner end of the slot, while the block has a shoulder 19 fitting and abutting against the outer ends of the slotted portions 2' A bolt 7' is passed transversely through the bed-beams and through said shank of the bearing-block. It will thus be observed that the pitman or toggle for actuating the pi'essenheacl, and also the presserhead, can be easilyremoved from the machine without separating or taking apart the frame by simply removing the bolts q r and sliding the bearing-block p rearwardly into the central open space until its shank leaves the said slotted portions r1 when the said block can be lifted from the open space between the bed-beams and the ends of the link h can be removed therefrom. The operation of again placing the parts in position and loosely confining the ends of the toggle-link is as easily performed, as the bearing-block with the link ends on its journal-bosses has merely to be placed in proper position between the bedbeams with its shank in the slot formed by the two slots of the two beams and the bolts g r placed in their proper positions. A most strong and rigid construction is thus provided for mounting the forward end of the toggle and of receiving the great forward thrust thereof when the machine is in operation, as it will be seen that the forward thrust of the toggle on the bearing-block is against the rigid shoulder formed by the shoulders of the two bed-beams and against the front ends of the slotted portions 11 which shoulders are rigid with the bed-beams and so that the said strain is directly longitudinal of the bedbeams, although any down strain thereon is resisted by the front axle, hereinafter mentioned, and by the rear supporting and securing device of said beams, hereinbefore described.

8 is a clevis or cable-securing device which has its lower end forked and passed down through or into the recesses i 2' of the bedbeams and mounted on and secured by the bolt 1*, while the upper end of the clevis, above the bed-beams, has an eye to which the operating-cable is secured, as hereinafter described.

Just in advance of the slotted portions of the bed-beams and of the bearing-block said beams have a vertical recess therethrough in which a pulley t is located, turning freely on the horizontal bolt or pin 15', passing through the bed-beams.

Just in rear of the lug (2 of the end head of the frame the bed'beams come together and engage each other and are formed with the transverse vertical semicylindrical grooves, which coincide to form the vertical bolt-hole 2' extending from the top to the bottom of the beams to receive the vertical kingbolt it, having a suitable nut or other looking device at its upper end at the upper sides .of the bed-beams, andan annular shoulder a, fitting the under sides of the bed-beams. At a distance below said shoulder said bolt has the enlarged circular flange or head U2, rounded or convexed on the upper surface and flat on the under side, which rests on the upper edge of the front axle o of the press, while the lower end of the bolt beneath said flange is rounded (see id) and fits and rests in an upwardly-flaring rounded socket or seat o in the upper side of the axle. Plates 1: v are secured by suitable bolts at the front and rear edges of the axle with flanges or lips '0 projecting over the rounded upper face of the flange or head a of the king-bolt and beveled or curved at their under faces, so that the front axle is free to turn on the lower end of the bolt and its ends can swing vertically on the lower rounded endof the bolt as a fulcrum, which movement is permitted by the rounded surfaces of the flange n and the lips or flanges of the plates v while the axle has an extended bearing and base where the broad flange or head a of the king-bolt rests thereon.

The front axle is provided with suitable supporting-wheels w, and a rear axle 5c is provided also, having supporting-wheels w mounted thereon.

The rear axle w is usually secured rigidly to the frame beneath the front portion of the baling-chamber and has the tie-rods or rigidly secured thereto at their rear ends and at their front ends rigidly secured to the vertical bolts m wt, preferably at the lower ends of said bolts just beneath the two cross-heads uniting the bed-beams, so that the front and rear axles are tied together and also to the frame and bed-beams, whereby the strain is generally distributed throughout the various parts of the framework of the machine and a most strong and rigid structure is attained.

y is a strongly-constructed brace or leg extending in an inclined position downwardly and forwardly from the front end of the machine to engage the ground. The upper end of the leg is bifurcated to embrace the lug cl and fit between the front ends of the bedbeams, and said ends are perforated transversely to receive the pin securing the'front ends of the bed-beams to the said lug and which also serves to secure the said leg. A brace or tie rod y is at the front end secured to an intermediate portion of the logy and at its upper rear end secured to a rigid part of the machine, such as one of the bed-beams. This leg, having its lower forwardly-inclined end engaging the ground, materially aids in holding the machine against forward movement, particularly when a plank, stake, or other obstruction is placed in front of the lower end of the leg to prevent forward movement of the leg and cause its front end to take into the ground and thus lock the machine in place.

The lower free end of the leg y has a slight vertical movement, and hence its tendency is to cause its front end to swing down and take into the ground under forward strain on the machine, so that any forward movement of the machine would cause the front end of the.

machine to rise or lift up on the said leg.

2 is a coiled retracting-sprin g for returning the presser when pressed rearwardly to its limit of rearward movement and at the completion of each compressing stroke. This spring can be arranged and secured in any desirable manner, although it is here shown as secured to the link 7L and to the frame or a rigid part thereof.

Referring to the power for actuating and releasing the presser-head-actuating toggle, 3 is a rotary driveshaft arranged transversely of the frame and projecting at its ends beyond the same and usually mounted in suitable bearing or journal boxes mounted at the front portions of the upper sides of the top longitudinal frame-bars. At one end this shaft usually has the fiy or balance wheel 8' rigid therewith and at the opposite end the driving-pulley 3" rigid therewith, on which the driving-belt t from a steanrengine or other actuating means is arranged to constantly rotate said drive-shaft in the same direction. A wheel or disk 3 is also rigidly fixed on said drive-shaft 3 at the inner side of the drivingpulley, and this disk is provided with the eccentrically-arranged rigid stud 3, projecting inwardly therefrom and having a loose roller mounted thereon. The front end head of the frame is provided with a central opening and with suitable journal-boxes 5 5 on opposite sides of said opening, in which the trip-shaft 6 is mounted transversely of the said head, with its ends projecting beyond the same. This trip-shaft is arranged parallel with and a distance below and forwardly from the rotary drive-shaft and has the sheave 7 rigidly mounted on the central portion thereof and located in the said opening in the frame-head. The presser-head-operating toggle-cable 8 is at one end secured to and adapted to wind on said sheave, and from thence passes down around the pulley t and rearwardly beneath the bed-beams to the pulley 0, and from thence upwardly to the pulley 7r at the joint in the toggle, and over the same and forwardly and downwardly to the clevis s, to which the end of the cable is securely fastened. It will be observed that the point where the cable is secured to the clevis sis a distance below the horizontal plane of the joint of the toggle at all points in the path of movement of said joint of the toggle, and that the pulley 0 is also below the plane of said joint of the toggle and rearwardly of the same, and that the length of the cable between said clevis and pulley 0 is stretched over the joint of the toggle. Hence when the cable is wound on the sheave 7, the toggle being doubled up and the presser-head at its limit of forward movement, the cable draws down the joint of the toggle and straightens the same with great force and power, thereby driving in the presser-head to perform its pressing operation, as shown in Fig. 3.

The end of the trip-shaft adjacent to the wheel or disk 3 of the rotary drive-shaft is provided with the trip 9, arranged in the cir cular path of the stud or projection 23 011 said disk. This trip is strongly constructed and is at its inner end rigidly secured to the tripshaft and extends laterally or radially therefrom beside the disk 3 and is of such length and so arranged in relation to the stud 3 that when the presser-head rebounds and reaches its limit of forward movement the 'trip is at its operative limit of forward movement with its extremity just within the path of rotation of said projection, about as shown in the diagrammatical view Fig. 13. As the drive-shaft revolves the said projection 3 engages the edge of the trip near the extremity thereof and forces the trip around ahead of the projection, the projection moving along toward the inner end of the trip, thereby moving the trip in a direction which rotates the trip-shaft and Winds up the cable on the sheave of the trip-shaft and forces the presser-head into the baling-chamber in its compressing stroke. When the projection 3 reaches its limit of inward movement on the edge of the trip, the presser-head has completed one-half of its inward or compressing stroke and the projection reaches its limit of inward movement on the trip as it passes around under or beside the end of the trip-shaft and as the trip enters the plane connecting or in which the driveshaft and the trip-shaft are located. As the projection forces the trip beyond said plane the presser-head starts in on the second half of its compressing stroke, and the projection travels toward the outer end of the trip, and as the projection reaches the end, or nearly reaches the end, of the trip the presser-head reaches that part of the baling-chamber where it meets the greatest resistance from the compressed hay. Thus when the presser-head reaches the point of greatest resistance to its further rearward progress the projection 3" is near the end of the trip, and hence exerting great force and leverage on the trip-shaft in rotating the same to wind the toggle-operating cable on the sheave. The projection 3 hence reaches a point near the end of the trip and has its greatest leverage on the trip-shaft when the presser about reaches the limit of its compressing stroke. As the trip-actuating projection continues to move around it presses the trip inwardly and slips off the rounded end of the trip and passes around beyond the same after it has swung the trip around about two-thirds or two hundred and forty degrees of a complete circle. The trip and its shaft being thus released, the plunger at once rebounds under the action of the retracting-spring 2 and the elasticity of the compressed hay, thereby drawing up the toggleoperating cable and unwinding the same from the sheave and rotating the trip to throw the trip back again to its start position with its extremity in the path of the trip-operating projection in readiness to be engaged thereby and again swung around to repeat the compressing operation. A most rapid, simple, and exceedingly powerful presser-head-operating power is thus provided for rebounding presser-heads which exerts the greatest power and leverage on the presser-head at the beginning and completion of its compressing stroke.

The engaging edge or surface of the trip is preferably curved,with the intermediate concave depression terminating in the roundedout or convexed surfaces toward the ends of the trip, so that an extended hearing or engaging surface is provided for the circularlymoving trip-operating projection which extends the swing of the trip and stroke of the presser-hcad.

The power can be easily and quickly thrown out of gear, so that the driving-shaft 3 can continue to rotate without rotating the tripshaft or presser-head, by simply rotating the trip-shaft after the presser-head has rebounded, and the trip is in its normal position at the starting-point to move the trip in toward the driving-shaft, so that its extremity passes in beneath the trip and out of the circular path of said projection. The projection is thus free to travel completely around the trip without engaging the same. Various means can be provided to thus throw the trip out of gear and back to its operative position at the starting-point. As an example of several constructions which can be provided for this purpose I show a cross-head 10, rigid on the end of the trip-shaft opposite the trip, having the upper and lower flexible connections 11 11 secured to the opposite ends thereof and extending rearwardly along the exterior of the side of the machine to and secured to an upright lever 12 at opposite sides of the fulcrum-point 13 thereof. Other operating means can be employed instead of the lever, which is usuallyfulcrumed at the side of the rear portion of the baling-chamber within convenient reach of the persons feeding the machine and applying the bale-ties. This lever is mounted to swing in a plane parallel with the length of the machine and is provided with any suitable locking means, as a spring-pawl and toothed segment. Each connection 11 has a coiled retractive spring 14, interposed therein and forming a part of the connection. The parts are so arranged that the trip. It should be noted that the crosshead 10 turns with the trip-shaft, so that during the compressing operation the lower connection 11 slackens while the upper connection tightens and expands the coil-spring therein, and on the release of the trip and rebound of the plunger the cross-head and connections assume their normal positions shown in Fig. 10. The trip is thrown in out of operative position, as described, by throwing the upper end of the lever 12 rearwardly and thereby tightening the upper connection 11 and turning the trip-shaft to rock the trip out of the path of the trip-operating projection.

A feeding device can be provided to intermittingly or periodically force the hay down through the feeding-opening into the balingchamber in front of the presser-head and after each rebound thereof. To accomplish this object a rock-shaft 15 is mounted transversely on the frame-bars a at a point between the power and the baling-chambeiz This shaft has an arm 16 rigid therewith and cxtendin g laterally therefrom and rearwardly over the machine with its rear end curved down and formed with an enlarged head or rake 17, which is normally located a distance above the feed-opening of the baling-chamber. An operating-arm 18 is rigid with and extends forwardly from said rock-shaft, with the curved end arranged at such a point in the circular path of the trip-operating projection 3 that the projection will move up beneath and engage said arm 18 and lift the same, and hence force the feeder rake or head 17 down into the baling-chamber just after the presser-head has in its rebound passed forwardly from beneath said opening. After the trip-operating projection has operated the feeder to force and press down a sufficient quantity of hay in front of the presser-head the said projection slips past the curved end of said arm 18 and the feeder returns to its normal position, with the rake-head 1'7 elevated and the arm 18 engaging and resting against a rigid stop 20. The feeder can be constructed in any suitable manner to normally maintain the elevated position of the rake-head, as by having the arm 18 weighted or formed heavier than the opposite end carrying the rake-head. In this connection it should be noted that the presser-head of the machine carrie. as usual, an apron, (not here shown,) which closes the feeding-opening of the baling-chamber when the head is performing the compressing operation and which moves back to open the feedingopening when the head rebounds. This apron can be of any ordinary andsuitable construction, such as is well known to those skilled in the art.

It is evident that various changes and modifications might be made in the forms, constructions, and arrangements of the parts dc scribed without departing from the spirit and scope of my invention. Hence I do not wish to limit my invention to the constructions specifically set forth herein, but con si d or in yself entitled to all such changes and variations as fall within the spirit and scope of my invention.
