BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent N0. 789,235, dated May 9, 1905.

Application filed June 8, 1904:. Serial No. 211,723.

To all whom it may concern.-

Be itknown that I, GEORGE E. RIDER, acitizen of the United States, residing at Kansas (lity, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Bailing-Presses, of which the following is a specification.

This invention relates to baling-presses, and has for its object to produce a power mechanism for imparting to the plunger a longer stroke with substantially the same travel of the team than is customary in this class of machine and in which, furthermore, the greater portion of the stroke is by direct application of power between the trip-lever and the plungerbeam.

To this end the invention consists in certain novel and peculiar features of construction and combinations of parts, 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-prcss, the section being taken just below the sweep-head. Fig. 2 is a section taken on the line 11 H. of Fig. 1. Fig. 3 is a front end view with the axle broken away. Fig. 4: is a central vertical section of the po wershaft and a portion of the swinging links carrying the same. Fig. 5 is a section similar to Fig. 1, but showing a modified construction. Fig. 6 is a vertical section taken on the dotted line 1V IV of Fig. 5.

In the said drawings, where like referencenumerals designate corresponding parts in all the figures, 1 1 are the front wheels, 2 the front axle, 3 bearing-blocks upon the axle, and 4 U-bolts uniting the blocks rigidly to the axle.

5 is a circular base-plate mounted in blocks 3 and also bolted or otherwise rigidly secured to the axle, if desired.

6 is a sleeve portion projecting rearwardly from plate 5 and secured upon the front end of the reach 7, the latter being adapted to be secured at itsv opposite end to the baling-case. (Not shown.)

8 is a collar secured upon the reach in any suitable mannerand provided with a horizontal arm 9 and a trip-off lug 10, projectingupward from the right-hand end of said arm.

Projecting forwardly from the base-plate is a rib 11, the same extending at an angle of about forty-five degrees t-o*the axle, and cast with said rib and extending at right angles thereto is an I-shaped arm 12.

13 represents bolts securing rigidly upon arm 12 the abutment-plate 14, having its inner edge 15 disposed longitudinally of the machine and its rear edge recessed, as at 16.

17 designates a pair of horizontal links, one above and the other an equal distance below abutment-plate 14 and having enlargements 1-8 at one end, respectively engaging the upper and lower sides of and pivoted, as at 19, to the rear outer corner of the abutment-plate and having their opposite ends formed with smaller enlargements 20, pivotally connected, as at 21, to the upwardly and downwardly projecting bosses 23 of the plunger-beam head 22, said head being provided, as usual, with the pocket 2 in its front end, the plungerbeam proper, 25, resting upon the supportingarm 9 to the left of the trip-off lug 10.

26 designates the power-shaft, provided at its upper end with the sweep-head 27 and with a set-screw 28, the latter depending into the conical bore 29 of said shaft and engaging the cavity 31 in the upper end of the conical stub-shaft 32, which projects slightly below the power-shaft and terminates in a threaded stem 33, engaged by a retaining-nut 34L at its lower end. Midway its length the lower link 17 is provided with a hole 35, through which the threaded stem 33 extends, the retainingnut 3 L being disposed below said link to brace and reinforce the same. The upper link 17 is provided with an opening 36 to form a bearing for the power-shaft,and to widen,and therefore strengthen, such connection said link is provided with an upwardly-projecting flange 37. The power-shaft between said links is provided with the usual trip-lever, consisting of oppositely-projecting bifurcated arms 38, and journaled in the outer ends of said arms are the customary antifriction-rollers 39 in the horizontal plane of the abutment-plate and plunger-beam, extending longitudinally I the formerly rear roller (now the front roller) when at rest between the abutment-plate and rides upwardly out of the recess toward the said beam, with the front roller 39 juxtaposed with respect to the frontcorner of the plungerbeam head and the rear roller juxtaposed with respect to the corner of the abutment-plate, forming the junction between the straight side 15 and recessed rear end 16.

On Sheet 3 certain of the parts are of different form and proportion, and the links have a movable instead of a stationary fulcrumpoint. In said sheet the abutment-plate is prolonged rearwardly, and its rear end is preferably straight, as at 40, instead of recessed, as'at 16. The links 17 instead of being pivoted to the abutment-plate are pivoted, as at ll, to swing-arms 42, pivoted to said abutmentplate, as at 43, one of said arms being above and the other below the abutment-plate, and rearward of said arms, to limit their rearward movement, the abutment-plate is provided with upwardly and downwardly projecting stop-lugs 4A. The head of the plungerbeam is also preferably formed straight at its front end, as at 45, instead of having the pocket 24, and in this connection it will be noticed that the front trip-lever roller bears against the plunger-beam head rearward of its front end and the rear trip-lever roller against the straight side of the abutment-plate some distance forward of the rear end of the latter, which disposition of the parts in conjunction with the swing-arms gives a longer plungerstroke than can be obtained by the construction shown in Sheets 1 and 2.

In the practical operation of the machine, with reference first to the preferred construction it will be seen that as the power-shaft is rotated by the sweep (not shown) in the direction indicated by the arrow, Fig. 1, the opposite pressure of the front and rear rollers against the plunger-beam head and abutment-plate results in the gradual expansion of the toggle constituted by the plunger-beam and the links, the beam moving rearwardly and slightly to the left in the first part of this movement and the links swinging rearwardly fromfulcrum-point 19. As this movement takes place the rear roller rolls around the rear inner corner of the abutment-plate and enters the recess 16 of the latter, attaining this position by the time the pivotal point 21 is vertically above the axle, the front roller during such movement rolling around the front corner of the plunger-beam head and entering the pocket thereof at about the same moment the rear roller enters the recess 16. As the movement of the sweep continues the plunger-beam continues its rearward movement, but reversesits lateral movement, and at the same time the trip-lever rollers reverse their position with respect to the abutment and the plunger-beam head-that is to say,

rear inner corner of the abutment-plate, and the rear (formerly the front) roller rides out of the plunger-beam pocket toward its front inner corner, said rollers and the connected parts attaining substantially the position shown in dotted lines as the plunger-beam comes in contact with the trip-off lug 10, by which time its rear or compression stroke has been completed, and instantly thereafter the continued movement of the sweep swings the front roller inward of the abutment-plate and the rear roller from engagement with the plunger-beam head, which action is immediately followed by the recoil of the beam, the recoil of the plunger being produced by the usual spring, (not shown,) and in this recoil the plunger-beam returns the parts to their original position, as shown in full lines, it being understood, of course, that the powershaft having revolved in the swinging links a half-revolution now presents the originally rear roller to the front and the originally front roller to the rear. All subsequent operations are repetitions of those described.

In Sheet 3 the operation is'the same as that already described, except that by reason of the change of form and proportion of certain of the parts and the addition of the swingarms a stroke of greater length is produced. By reference .to Fig. 5 it will be seen that shortly before one-half of the compressionstroke is completed the rollers are engaging the front and rear sides, respectively, of the plunger-beam head and abutment-plate and that because up to this time there is a lateral pressure on the plunger-beam head and abutment-plate the swing-arms remain in longitudinal alinement with the links. 'hen the parts have assumed the position mentioned, as shown in dotted lines a, the swing-arms have reached their limit of rearward movement by engagement with the lugs 44:, so that in the continued movement of the sweep the pivotal points a1 form the fulcrums for the links. By the time the compression-stroke of the plunger-beam is ended, as shown by dotted lines 5, and its lateral movement terminates through the instrumentality of the trip-off lug 10 the trip-lever rollers. are rolling in opposite directions upon the rear end 40 of the abutment and front end of the plunger-beam head, one to clear the inner side of the abutment-plate and the other to clear the inner side of said head, and as soon as said results take place the recoil of the plunger-beamocours, and the parts are returned to their original positions, as shown in full lines, it being understood, of course, that the powershaft has completed a half-revolution, as explained in connection with the preferred construction.

In both cases it will be observed by reason of the oscillatory travel of the power-shaft that the team hitched to the sweep (not shown) will travel an elliptical path instead of in a circle, the sweep being so proportioned that the longest axis of the ellipse shall be longitudinal of the machine, so that when the recoil of the plunger takes place and the sweephead jumps back about fifteen inches in the proportion of parts shown the draft-animals will be at one side or the other of the machine. This action of the plunger in no way incommodes or affects the team because it is hardly perceptible at the front end of the twelve or fifteen foot sweep. There is a decided advantage, however, in having the team travel in the elongated path, as it gives the man feeding the baling material into the press more time, and therefore enables him to place heavier charges therein with less danger of having his foot crushed, it being well known that most feeders of horsepower haypresses ram the charge down through the feedopening into the baling-chamber by foot.

From the above description it will be apparent that I have produced a baling-press possessing the features of advantage enumerated as desirable in the statement of invention and which is obviously susceptible of modification as regards its form, proportion, detail construction, and arrangement of the parts without departing from the essential spirit and scope or sacrificing any'of its advantages.
