This invention relates to baling presses, and it is an object of the invention to provide a device of this kind which can be either manually operated or power operated.

It is also an object of the invention to provide a device of this kind embodying a reciprocating plunger together with means whereby said plunger may at will be rendered inoperative at any point of its stroke and which is particularly desirable in the event of accident.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved baling press whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more full set forth. I

The novel features of my invention will hereinafter be definitely claimed. 7

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein i Figure 1 is a view in side elevation of a,

baling press constructed in accordance with an embodiment of my invention;

Figure 2 is a view in top plan of the device as herein disclosed;

Figure 3 is an enlarged fragmentary view partly in section and partly in elevation illustrating in detail the mounting of one ofthe bale holding dogs;

Figure l is a longitudinal vertical sectional view taken through the device as herein disclosed with certain of the parts in elevation;

Figure 5 is an enlarged fragmentary view partly in vertical section and partly in elevation illustrating the mounting of the end lever together with the parts associated therewith V Figure 6 is a fragmentary View in bottom plan of the rock arm for normally maintaining the plunger in operative engagement with the power wheel.

As disclosed in the accompanying drawings, B denotes a baling chamber disposed on a gradual slope from front to back to reduce friction of the bale as it passes therethrough, and the forward end portion of the chamber 13 in its top is provided with a conventional feeding opening 1. The rear or discharge end of the chamber 13 is adapted to be closed by the swinging door D held in closed position by. a latch 3 coacting with an outstanding arm 4 carried by the door D.

The side walls 5 at the forward end of the chamber B are provided with elongated slots termediate offset part or crank 10 with which en agesa. spring pressed arm 11 whereby the dog is normally maintained projected within the chamber B yet may be forced outwardly therefrom to permit the rearward passage of a follower F and thehay or kindred material being compressed by theplunger P..

The bottom 12 of the chamber B is continued a desired distancein advance of the open forwarder front end of the chamber and, as herein disclosed, said extended portion of the bottom 12 is supported by a sill 14. The plunger P is of a reciprocating type and travels over and along the bottom 12 of the chamber B and is provided in its side marginal portions with the slots 14 to permit the plunger to readily pass the portions of the dogs 7 projected within the chamber B upon travel of the plunger P in either direction. To further facilitate the proper entry of the plunger P within the compression portion of the chamber B, a roller 15 is rotatably supported between the side walls of the chamber B in the upper part thereof and immediately adjacent to the inner or rear margin of the opening 1.

The plunger P has extending outwardly from its side faces the trunnions 16 upon which are mounted the rollers 17, said rollers working within the longitudinally disposed 100 .6 through which work the horizontally other mechanism. associated therewith.

The plunger? has extending forwardly therefrom an elongated member or beam 19, said member or beam 19 and plunger P con stituting a rigid structure with the member or beam arranged centrally of the plunger P. The member or beam 19 has its outer portion bifurcated and at opposite sides of the kerf 20 the member or beam 19 is provided in its upper face with the racks 21 with which engage the oppositely and laterally directed trunnions 22 carried by a wheel 23. The trunnions 22 have mounted thereon anti-friction sleeves 24 and the wheel 23 is rotatably mounted upon a supporting shaft 25 carried by and bridging the space between a pair of upstanding posts 26 anchored to the sill 14. The trunnions 22 are arranged in a partial circular series. and are of a number suflicient upon a single rotation of the wheel 23 to force the plunger P inwardly of the baling chamber B and at the same time permitting the desired return stroke of the plunger P. This return stroke is accomplished by a retractile member-27 of requisite tension and herein disclosed as a coil spring, having one end suitably anchoredto the lower portion of the plunger P and its opposite end portion suitably anchored to the outer end portion of the sill 14.

It is believed to be obvious that as the plunger P is forcedinwardly this retractile member or spring 27 is placed under tension so that as the end trunnion 22 leaves the member or beam 19 upon its compression stroke,

. the plunger P will immediately return to a position in advance of the opening 1. Upon continued rotation of the plunger P hay or kindred material is effectively baled in a Well known manner within the chamber B.

The member or beam 19 is normally maintained in a raised or elevated position for properengagement of the trunnions 22 with the racks21 through the instrumentality of a vertically swinging rock arm 28 rotatably su'pportechas at 29, upon the sill 14. The upper or free end portion of this arm 28is continued by a cross member 30 underlying the beam or member 19 and carrying an antifric'tion sleeve or roller 31 which has direct contact with said member or beam 19 from below. The pivoted end portion ofthe arm. 28 iscontinued by a stub shaft 32 through which is fired an upstanding rock arm 33. The upper portion of this arm 33 is connected by a retractile member 34, herein disclosed as a coil spring, with a lever 35. This lever 35 is normally disposed in a vertical direction and has its lower end portion pivotally connected,

as at 36, with a side wall of the chamber B 37 the rock arm 33 will become ineffective and the member or beam 19 will drop sufficient to disengage the racks 21 from the trunnions 22. The wheel 23 works within the kerf 20 of the member or beam 19 and at its periphery is provided therealong'with the teeth 38 with which is adapted to engage a gravity pawl 39 pivotally connected, as at 40, with'a hand lever 41. The hand lever 41 at its lower portion is provided with the arms 42 provided at their free, ends with the sleevesor collars 43 freely mounted upon the opposite end portions of the hubs44 of the wheel 23. As the hand lever 41 is oscillated the wheel 23' will be manually driven to effect the desired compression stroke ofthe plunger P. Retrograde movement of the wheel 23 is prevented by a holding dog 45 pivotally mounted, as at 46,

and engagii'ig by gravity the teeth 38 of the wheel Rotatably supported by a side wall of the device adjacent the wheel 23 is a shaft 47 provided with a rock arm 48 adapted, upon rotation or rocking movement of the shaft 47 in one direction, to contact from above with the member or beam 19 so that the member or beam 19 may be thrown out of operative engagement with the wheel 23 at any time duringthe movement of the plunger Pand which is of especial importance or advantage in case of accident. Theshaft 47 at its-outer portion is provided with an elongated operating lever 49 which may be readily grasped and manipulated by an individual. The rock arm 48 is normally maintained in position out of contact with the member or beam 19 by a resilient holding arm 50 extending outwardly from a side wall of the device and upon which the lever 49 rests from above. I?

In case of emergency it is only necessary that this lever 49 be pressed downwardly, the resiliency of the arm 50 readily permitting such operation.

The side Walls of the chamber B at their forward ends are continued by the horizontally disposed frame members 51 which are also suitably connected to the upstanding posts 26. These frame members 51 are provided with bearings 52 for the parallel shafts spaced gears 56 and 57.and upon proper adeam justment of said shaft 54 the gear 56 is brought into mesh with the peripheral teeth of the wheel 23 while the gear 57 is brought into meshwith a gear 58 carried by the shaft 53. By this means the plunger P may be power driven.

If preferred, the pulley may be attached directly to the shaft 54 and in which event the shaft 53 is unnecessary but by use of these thrown into inoperative position when desired.

As is particularly illustrated in Figure 4 it is to be noted that the trunnions 22 are substantially in a spiral arrangement with the high or outermost trunnion first engaging the member or beam 19 to force the plunger P inwardly. By this particular arrangement of the trunnions 22 the power imposed upon the plunger P is increased and at the times such increase is required.

Inwardly of the frame members 51 are the supplemental horizontally disposed frame members 60 each being of a length, as illustrated in Fi ures 1 and 2, to extend beyond the outer end of the members 51. These members 60 are arranged at opposite sides of the wheel 23 and below the hub thereof and coact with the side marginal portions 61 (Figure 5) to limit the upward movement of the member or beam 19 of the plunger P on its back or returned stroke so that the plunger will not interfere with any of the parts of the device.

The outer or extended end portion of each of these members carries a depending latch bar 62 with which is adapted to engage an upstanding catch 63 carried by a side face of the member or beam 19 of the plunger P as illustrated in Figure l of the drawings.

The plun er P, under power, passes into the feed chamber of the press as far as required to compress the hay or the like to the desired density. As hereinbefore described, the plunger P is automatically released and by means of the coil spring 27 it is pulled backward. Upon its return the plunger P will strike the wheel 23 with sufficient force to permit a rebound of the plunger P to reenter the feed chamber of the press a distance sufficient to obstruct, in a measure, the delivery of the hay or the like into the feed chamber. However, by provision of the bars 62 and catches 63, upon this return of the plunger P the engagement of the catches 63 with the bars 62 will prevent such rebound.

* As the trunnions 22 engage the racks 21, the

catches 63 will be released from the latch bars 62, thus permitting the desired working stroke of the plunger P. 1 1

From the foregoing description it is thought to be obvious that a baling press constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
