BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 297,299, dated April 22, 1884.

Application filed September 25, 1883. (No model.)

To aZZ whont it may concern.-

' Be it known that we, HENRY V. SCATTER- GOOD and CHARLES F. SOATTERGOOD, both of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Baling-Presses, of which the following is a full, clear, and exact'tlescription, reference being had to the accompanying drawings, making part of this specification, and in whicl1 Figure 1 is aside elevation of our press; Fig. 2, a plan View; Fig. 3, a longitudinal section; Fig. 4, a horizontal section at the line or a: on Fig. 1; Fig. 5, an enlarged and detached plan view of the automatically-extensible sweep; and Figs. 6, 7, 8, and 9 are enlarged and detached details of the pressure-resisting bars and their stop devices.

Our invention relates to improvements in horizontal baling-presses; and it consists of the mechanisms illustrated in the drawings and described herein.

As represented in the drawings, A is the framework of the press, which we preferably make in the form shown, but which may be varied in form to suit the different purposes for which the press may be used.

B is the baling-chamber. The top and bottom of said chamber are closed over, but the vertical sides are made of ribs 1), (preferably of metal,) for the purpose of forming the longitudinal slots 1), to facilitate the tying-off of the bales.

O is a plunger adapted to reciprocate in a close chamber, B, formed in front of the baling-chamber B. The said plunger is provided with a metallic head, 0, in the face of which are horizontal tying-slots c, that correspond in position with the slots 1), and at each end of the slots a beveled recesses c are formed fora purpose hereinafter described. A forward extension, C, of the plunger G is provided with a journal-box, 0 for receiving the wristpin of the operating mechanism.

D is the crank-wheels of the plunger-operating mechanism. The said wheels are secured to oppositely-located separate shafts, d,

and to a wrist-pin, d, in such manner that the said wheels, shafts, and wrist-pin will move as one piece. The shafts d have their journals in the swinging ends of the vibratile links E,

which have their opposite ends attached to a shaft, F, that is held in a fixed place by brackets f, secured to the frame-work A. Said shaft passes through a slotted opening, 0, in the extension G of the plunger. By this arrangement of the parts of the operating mechanism the path of the wrist-pin (1 follows a direct line, while the center line of the shafts (1 will move in an arc of a circle whose radius is equal to the distance between the centers of the hubs of the links E.

To the outer end of the upper shaft, (7, a sweep, G, is attached for the purpose of operating the press by animal-power. Said sweep we preferably make automatically extensible, and for this purpose we attach to the sweep G asliding piece, G, and as one means for antomatically effecting the lengthening of said sweep, we connect the sliding piece G, by means of friction-rollers g, to a cam-shaped rim, e, formed upon the end of the uppermost link, E, said rim so arranged in respect to the center line of the shafts cl that while the plunger 0 is approaching to or receding from its extreme inward movement, the sliding piece G will slide outward to givethe sweep its greatest length, and at the opposite phase of the movement of the plunger the sliding piece will be drawn in to give the sweep its least length; and in this manner it will be readily seen that the length of the sweep will be automatically varied to suit the exigencies of the work to be performed.

The means for producing the extension of the sweep may be varied in several ways. For instance, eccentric-wheels may be substituted for the cam-shaped rim. Said wheels, when properly connected to the sliding-piece G,will produce the same effect in lengthening and shortening the sweep.

For the purpose of avoiding the damage 00- casioned by arebound of the plunger 0, which rebound is produced by the resilient action of any elastic substance that is compressed in the press, and occurs at the moment the plunger commences its outward movement, we provide an automatic device for the prevention of such rebound, and by so doing prevent the sweep from being thrown violently against and injuring thelegs of the animals attached to the sweep.

The said prevention device consists of the following parts: The friction-band H surrounds the periphery of the upper wheel, D, and has one of its ends pivoted, as at h, to the upper link, E. An arm, I, carrying a friction-roller, i, is also pivoted to saidlink at h, and the opposite end of the friction-band is adjustably connected to the outer end of the arm I by means-of the screw-rod andznuts h. A camshaped swell, d, formed on the periphery of the upper wheel D, is so arranged that it will engage with the roller z to produce a vibratory movement of the arm I and effect a tightening of the friction-band H around the upper wheel,

D, at the moment the plunger 0 has reached the extreme point of its inward reciprocation. The swell (2 should be so proportioned that the friction-band II will continue to bind the wheel D until the compressed material has expanded sufficiently to relieve the'plunger G from any back-pressure, after which the roller 2 will pass onto the periphery of the wheel D, and thereby permit the band H to expand and free the wheel from its retarding action. By means of the screw-rod and nuts h, provision is made for increasing and decreasing the tension of the friction-band H, so as to produce a corresponding change in the frictional action of said band.

At the forward end of the balingchamber B arms J are arranged to swing on vertical shafts j, to pass into the slots b, for the purpose of retaining the successive charges of material and preventing them from following the return-stroke of the plunger 0. A spring, j, is applied to the back of each of the arms J, so as to force them inwardly. The free ends of the arms J are forced to swing outwardly by the incoming charges of material until the plunger completes its inward stroke, when said arms enter the recesses c of the plunger, as shown in Fig. 4-, where they will be in position to engage with the material in the press and retain it, as above set forth.

For the purpose of effecting a more perfect compression of the material, we provide our press with resistance-bars and stop devices. The resistance-bars K are made of metal, and are adapted to slide in the slots 1), and have in one or both edges longitudinal grooves 70, for passing the bale-ties through. The stop devices consist of the vertical shafts L, arranged in the sides of the press, near the rear end of the baling-chamber B. Said shafts are provided with arms '1, whose inner faces are flat, and coincide with the axial center line of the shafts, as clearly shown in Figs. 8 and 9. The arms I are arranged at intervals, which coincide with the slots 11, so that said arms can be moved into said slots. The

shafts L are cut away to form the flat faces of the arms Z, and thereby suitable passages are formed crosswise of the shafts for the resistence-bars K to pass through when the arms Z are turned in the position shown in Fig. 9. Levers Z, secured to the upper ends of the shafts L, affords means for turning said shafts whenever occasion requires. A feeding-opening, M, is made in the upper side of the pressframing in such position that the material to be compressed can be fed into the chamber B when the plunger 0 is drawn forward to the extreme of its movement in that direction, which position is indicated by the dotted lines in Fig. 8. On the completion of abale, after it has been tied off, a set of resistancebars, K, is placed through the slots 1) to lie against the forward end of the finished bale, and the arms Zare turned into the positions shown in Fig. 9 to permit the resistance-bars that are against the rear end of the finished bale to pass through. Then as the charges of -materials for a new bale are pressed in, the

finished bale is pushed rearward and finally ejected from the rear end of the press. As soon as the resistance-bars K'have been-pushed past the shaft, L, the latter may be turned to bring the arms Zinto position shown in Fig. 8 to engage and retain the incoming set of resistance-bars until the new bale has received its required compression.

We claim as our invention- 1. In a press, the combination, with. a reciprocating plunger, of a plunger-operating mechanism consisting of a crank motion, whose shafts have their bearings in the swinging ends of vibratile links, the opposite ends of said links being pivoted at afixed point on the press-frame, substantially as specified.

2. In a press, the combination, withaplunger and its operating mechanism, of an automaticbrake mechanism adapted to prevent the rebound of the plunger, substantially as herein specified.

3. In a press, the combination, with a reciprocating plunger and its operating mech anism, of an extensible sweep or lever which has its maximum length when the plunger meets with the greatest resistance, and its minimum length when the plunger meets wit-11 the least resistance, as herein specified.

4. The resistance-bars K, having in one or both edges longitudinal grooves k, as and for the purpose herein specified.

5. In a press, the combination, with the resistancebars K, of the shafts L, arranged as herein described, and for the purpose specified.
