BALING FRESS'.

SPECIFICATION forming part of Letters Patent No. 788,613, dated May 2, 1905.

Application filed April 25, 1904. Renewed January 3,1905. Serial No. 239,427.

To (all 11/72/0727. it may concern.-

Be it known that I, J OSIAII S. TUT'ILE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in BflliUg-PIBSSGS, of which the following is a specification.

My invention relates to baling-presses, and has for its object to produce a two-stroke horse-power press which operates eiiiciently and reliably and is of simple, compact, strong, and durable construction.

To this end the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1 is a horizontal section of the power end of a baling-press taken just below the sweep. Fig. 2 is a vertical section taken on the line II II of Fig. 1. Fig. 3 is a crosssection taken on the line III III of Fig. 1.

Referring to the drawings in detail, 1 designates the front wheels, and 2 the front axle.

3 designates blocks secured to the axle, and 4 a circular base-plate above the axle and secured in blocks 3 and furthermore bolted to the axle, as at 5.

6 designates a pair of longitudinally-extending angle-irons just above the base-plate and having their front ends terminating in a return bend or gooseneck 7, said angle-irons, in conjunction with the connectingplate 8, forming the reach which is the main connection between the power mechanism and the balingcase. (Not shown.)

9 is a casting secured to the upper end of the gooseneck, and 10 bolts connecting said casting with a second casting 11, the last-named casting being connected by the usual tie-bar 11 with the bailing-case. The castings form a journalfor the upper portion of the powershaft 12, equipped at its upper end with the customary or any preferred sweep and near its lower end with op positely-projecting arms 14, provided with antifriction-rollers 15, the lower end of the power-shaft being journaled in the base-plate in any suitable or preferred manner.

All of the parts thus far described, indi vidually and as arranged, are of common and well-known construction and for this reason need no minute description.

16 is a casting secured in any suitable manner upon the reach and provided with a later ally-projecting shaft or arm 17 as a support for the free end of the plunger-beam 18, the latter being provided, as usual, with the casthead 19, having a pocket 20 in its front end. At its inner edge the plunger-beam is provided with a bracket 21, which by contaetwith casting 16 is adapted to limit the lateral movement of the plunger-beam toward said casting in order to effect the release of the plunger-beam from the trip-lever at the proper point and the recoil of the plunger-beam at the proper side of the power-shaft, as hereinafter explained.

Pivoted upon plate 22, secured to casting 16 in any suitable manner, is a lever 23, pref erably of malleable iron, and said lever at the point where is imposed the greatest strain is humped inward, as at 24:, to increase its strength. Forward of said hump the edge of the lever which opposes the trip-arms is concaved, as at 25, and forward of said concaved surface it has a second concaved surface 26 for a purpose which hereinafter appears. Near the heel or pivoted end of the lever and at its outer side it is formed with a cam-surface 27 for a purpose which is hereinafter explained.

The lever 23 extends through a slot which, in effect, is a slot of the plunger-beam, as it is formed by a pair of plates 28, a roller 29 connecting the ends of said plates outward and the plunger-beam inward of said lever, the plates being bolted, as at 30, to the plunger-beam. The slot is made of greater width in a vertical direction than the beam itself by making the plates of angular or step-like form when viewed from the front or rear of the machine, as shown most clearly at 31, Fig. 3. By this construction a slot of suflicient width is provided to accommodate the operation therein of the trip-lever arms, as will be readily seen by reference to Figs. 2 and 3.

In operation as the sweep is moved in the direction indicated. by the arrow, Fig. 1, the rollers 15 of the front and rear trip-lever arms, respectively, engage the inner side of the plunger and the concaved surface 25 of lever 23. As a result the free ends of the plunger-beam and lever move apart and form a gradually-widening wedge, which by pressure on roller 29 compels the plunger-beam to move rearwardly with great rapidity, as the first two-thirds or three-fifths of the stroke is opposed only by the loosely-bunched hay in the baling-chamber. When abouthalf the power-stroke has been made, as indicated by dotted lines, Fig. 1, the front roller 15 is rounding the corner of the plunger-beam and the other roller 15 has nearly reached the front end of concaved surface 25. At this time the lateral strain on the plunger-beam and lever is greater than at any other time, and for this reason I preferably hump the lever inward, as at 24, because at the time mentioned the roller 29 is engaging the outer side of the lever opposite to said humped portion. As said trip-lever rollers respectively enter the pocket and clear the front end of surface 25 the lateral strain on the plunger-beam and lever ceases, as in the further travel of the plunger-beam the concaved surface 26 of the lever by engagement with the trip-lever roller ust previously engaged with surface 25 simply acts to hold the lever swung outward a suflicient distance to engage roller 29, and thus prevent any possibility of the plungerbeam slipping out of engagement with the engaging trip-lever roller and rebounding before its power-stroke has been completed. In practice, however, the concave surface 26 of lever 23 may be dispensed with, as it is found that the pressure of the trip-lever roller in the pocket of the beam is so great that accidental dislocation never occurs. As the slow and powerful portion of the stroke progresses-viz, that portion which follows the entrance of the roller into the pocketthe roller 29 travels along cam-surface 27, but not necessarily in contact therewith, and as the stroke is finally completed said roller is disposed near the heel or rear end of said cam-surface. As the stroke is completed the bracket 21 strikes casting 16 and arrests lateral movement of the beam, so that as it is tripped from the roller by the continued movement of the latter it shall rebound at the proper side of the power-shaft. In this re bound there is a tendency of the beam to swing outward too far from shaft 12, and to prevent this outward movement in its inceplJIOII lZhG cam is provided, the roller 29, as the recoil begins, coming in contact with cam-surface 27. In the recoil the roller 29 follows approximately the curvature of the outer side of the lever and by engagement with the convex outer portion 82,.opposite concave portion 25, serves to return the front end of the plunger -beam to its original position, the usual or any preferred mechanism (not shown) being employed to arrest the recoil movement in the customary manner.

All future operations are repetitions of those described.

From the above description it will be apparent that I have produced a baling-press which embodies the features of advantage enumerated as desirable in the statement of invention, and while I have illustrated and described the preferred embodiment of the same it is apparent that various changes may be resorted to without departing from the essential spirit and scope or sacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a baling-press, the combination of a plunger-beam having a laterally-extending slot, a lever pivoted to a fixed point of the press for movement in a horizontal plane and extending forwardly through said slot, and means for pressing the front ends of the plunger-beam and lever apart to effect the power-stroke of the former.

2. In a baling-press, the combination of a plunger-beam having a laterally-extending slot, a lever pivoted to a fixed point of the press for movement in a horizontal plane and extending forwardly through said slot, and a trip-lever for pressing the free ends of said beam and lever apart to effect the power-stroke of the former.

3. In a baling-press, the combination of a plunger-beam having a laterally-extending slot, a lever pivoted to a fixed point of the press for movement in a horizontal plane and extending forwardly through said slot, means for pressing the front ends of the plunger-beam and lever apart to effect the power-stroke of the former,and means to trip the pl Linger-beam from the means for operating it to permit the former to recoil.
