BALlNG-PRESS- SPECIFICATION forming part of Letters Patent No. 760,117, dated May 17, 1904.

Application filed October 15, 1902. Serial No. 127,402. (No model.)

to provide certain new and useful improve ments in the construction shown in my prior patent, No. 685,838, dated November 5, 1901.

It is furthermore designed to provide improvements in the mounting of the plungeroperating lever, so as to insure a quick and positive disengagement thereof from the plunger-rod at the completion of the stroke and also to arrange for applying the power to the lever in such a manner as to obviate twisting thereof.

Another object is to provide an improved tension device for the plunger-operating lever and to have the same adjustable, so as to take up wear and to accommodate the device to existing circumstances.

Another object is to provide the press with means whereby all of the bales may be formed of equal lengths.

Other objects reside in the provision of an improved tucker and also means for preventing backward movement of the bales.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described. shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a baling-press constructed and arranged in accordance with the present invention. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a cross-sectional view on the line 8 3 of Fig. 2. Fig. 4: is a cross-section on the line 4 4 of Fig. 2. Fig. 5 is adetail perspective view of one of the devices for preventing backward movement of the bales. Fig. 6 is a detail plan view of the means for indicating when a bale has been completed.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

The frame of the present press consists of opposite longitudinal sills 1, which are con.- nected by suitable cross-bars 2 and from which rise end and intermediate posts 3 and L-respectively. Opposite longitudinal sides 5 are secured to the posts, and a top 6 and bottom 7 are provided at the rear portion of the frame, so as to form an elongated baling-box. Thisframe structure is supported upon a suitable running-gear or wheels for convenience in transportation.

The press-box proper is defined between the intermediate posts 4 and is provided in its top with a feed-opening 8, from which rises a suitable hopper 9.- At the rear end of the feedopening each upper edge thereof is provided with a vertical slot 10., which receives the ad jacent journal 11 of a roller 12, which is thus mounted within the top of the feed-opening so as to project slightly below the top of the baling-box and is designed to form a tucker for tucking the hay into the box and is also an an tifriction device to prevent binding of the hay against the back of the opening. In order that the roller may yield in a vertical direction, so as to prevent injury to the journals or frame of the machine, each journal is projected externally of the box and is received within a terminal eye 13, carried by the free'end of a leaf-spring 14:, the forward end of which is secured to a block or projection 15, carried by the outside of the box. To prevent back: wardmovement of the bales, there is provided mean at opposite sides of the box consisting of av pair of upper and lower metallic plates 16, which are applied longitudinally to the exterior of the box, with their-forward ends wardly through an opening 19 in the side of the box and is inclined rearwardly, so as to present a beveled or inclined front face and an abrupt rear shoulder, whereby the projections and plates will yield outwardly when the bales are being forced along under the action of the plunger; but the projections will offer a stationary abutment to prevent backward movement of the bales. By folding the plate to provide a projection the latter is materially strengthened, and by having the free terminal of the plate bear against the outer side of the box it limits the inward movement of the projection to prevent the'plunger from catching on the projection during its rebounding movement.

A Very important object of the present invention is to provide for insuring auniform length to the bales, and this is accomplished by means of a wheel or roller 20, turning in a longitudinal slot or opening 21, formed in the top of the baling-box and immediately in rear of the press-box, with its lower peripheral edge projected below the top of the box, so as to frictionally turn upon the tops of the bales. The roller is yieldably mounted, so as to prevent binding thereof upon the bales, by means of a pair of spring-arms 22, secured to the top of the box and provided at their free ends with bearing-eyes 23, which receive the journals of the roller or wheel. Upon the periphery of the wheel is a projection 24, which is adapted to strike against the free end of a spring-,knocker 25, which consists of an arm having its rear end secured to the top of the box and its forward free end provided on its under side with a head or enlargement 26 to snap down against a wear-plate 27 upon the top of the box after the free end of the springarm has been disengaged from the projection. It will of course be understood that the periphery of the wheel or roller is-of a predetermined length that is to say, it is of a length equal to the length of the bale to be formed by the press. Hence the amount of hay which is required to give the wheel or roller one complete rotation constitutes a single bale,

and the noise made by the spring tripping head or face plate 30 is secured to the end of the plunger, so as to have a working fit within device, so as to guide the plunger-rod and prevent lateral movement thereof. Uponthe top of the plunger there is a plate 35, which isdesigned to close the feed-opening when the plunger moves into the-press-box. The plate has its rear end upturned, as shown in Fig. 2, for the purpose of preventing the dust and trash from falling off the rear end of the plate and getting behind the plungerhead. The upturned rear end of the plate is adapted torake the material forward instead of passing under the same. In the upper side of the plunger-rod and just in front of the rear rollers 32 is a seat or. socket36, which is protected by a metallic wear-plate 37 and is designed to receive the lower end of the actuating-lever. The plunger is caused to rebound by means of a helical spring 38, which lies longitudinally beneath the plunger-rod,

vwith one end connected thereto and its opposite end connected to a cross-bar or abutment 39 at the rear end of the guideways in which the rollers 32 work. For operating the plunger there is an upstanding lever 40, which is fulcrumed intermediate of its ends upon a swinging support consisting of a pair of arms or members 41, whichembrace thelever, With sides of the arms or members, projects at opposite sides thereof, and has its forward or under face beveled, s0 asto strike flat against the stops 44, which are blocks secured to the sides of the apparatus and supported upon the upper pair of rails or cleats 33. The plungeroperating lever is preferably of wood and is strengthened by means of a pair of metallic bars or plates 45, the lower ends of which are,

projected beyond the end of the wooden portion of the lever, so as to form a fork 46, be: tween the members of which an antifrictionroller 47 is mounted, said roller being disposed inwardly from the ends of the fork members and adapted to engage the seat or socket 36 in the top of the plungenrod, the terminals of the fork members normally lying at opposite "sides of the plunger-rod, so as to form guards to prevent lateral displacement of the lever from the plunger.

The means for imparting motion to the plunger-actuating lever consists of a rope or cable 48, which has one end connected to an inverted substantially U-shaped bracket 49, which is secured to a cross-sill 50 at the front of the press, the said front being open to accommodate the bracket. Within this bracket is a grooved pulley 51, under which the free portion of the cableor rope passes, and is provided at its outer end with a whiffletree or other suitable draft connection 52. At the upper end of the plunger-actuating lever is a groove-pulley 53, which is mounted in a fork 54, formed by the upper ends of the plates or.

bars 45. The outer ends of the fork members project beyond the periphery of the pulley and are connected and braced by a rivet or cross-bar 55, which also forms a guard to prevent the rope or cable from accidental displacement from the pulley. Normally the roller 47 at the lower end of the actuating-le ver is in the seat or socket 36 of the plungerrod, so that when power is applied to the free end of the rope or cable the upper end of the plunger-actuating lever is drawn forwardly and its lower end moved rearwardly, thereby moving theplunger into the press-box and.

compressing the hay. As the lower endof the levermoves upwardly it finally disengages from the plunger, and the latter automatically rebounds to its original position under the influence of the spring 38, so as to be in position for another operation. After the lever has become disengaged from the plunger-rod it is drawn back to its original position through the influence of a helical spring 56, connected to the upper portion of the lever and also connected to the upper end of an upstanding substantially L-shaped spring-arm 57, which has its lower end connected to the top of the frame between the lever and the hopper. an adjusting-screw 58, which pierces the adjacent side of the hopper and the upstanding member of the L-shaped spring, with a nut 59 fitted to the extremity of the screw and bearing against the spring-arm, so as to form a tension device for maintaining the proper tension upon the spring-arm. By combining the spring-arm with thehelical spring a better effect is had to return the lever to its original position, and considerable strain is relieved from the helical spring, and the tension device is thereby rendered more durable. It will of course be understood that the lever is gradually drawn back to its original positionafter the completion of the stroke of the plunger without imparting a jar to the animals which are connected to the operating-rope. The purpose of the cross-bar 43 at the upper end of the arms 41 is to limit the downward swing of said arms by striking against the stop-blocks 44, whereby the lever has a movable or swinging fulcrum during its initial movement, resulting in arapid initialmovement of the lever and the plunger and a stationary fulcrum during the latter stages of its movement, resulting in a slower or more powerful movement to compress the hay in an effective manner.

To hold the press against movement when power is applied to the operating-rope, there is an anchoring device consisting of a yoke 60, swung or pivoted to the front end of the press and having its free end provided with an anchor-hook 61, which is forced into the ground when the team is driven away from the press, and there by prevents the latter from creeping or working forward.
