BALlNG-PRESS.

SPECIFICATION formingpart of Letters Patent No. 669,176, dated March 5, 1901.

Application tiled June l, 1900. Serial No. 185698. (No model.)

T0 all wwnt it vta/y concern/:-

Be it known that l, WINFIELD S. LIvEN- GOOD, a citizen of the United States, residing at Kansas City, inthe county of Wyandotte, in the State of Kansas, have invented certain new and useful Improvements in Baling- Pre'sses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in baling-presses of that type or class known as full-circle presses, in whicha plunger is operated by a pitman having a Vibrating end portion, and it has more particular reference to improvements in the means for controlling and operating the pitman of such a press; and my invention consists in certain features of novelty hereinafter described, and pointed out in the claims.

Figure 1 represents a plan view of the power end of a baling-press, showing the relation of the parts with the pitman at the extremity of the instroke, the trip-lever roll having just left the end of the pitman. Fig. 2 represents a plan view of the same, showing the relation of the parts with the pitman in two positionsfirst, in dotted lines showing the pitman at the extremity of the outs-troke or rebound, and, second, in heavy lines showing the pitman in the position at which the trip-lever roll enters the pocket and takes effect upon the end of the pitman. Fig. 3 represents a side elevation, the parts being in substantially the same position as shown in Fig. 1. Fig. 4 represents a detail view showing the relation of the stud upon the outer end of the swinging pitman-brake for limiting the outward movement of the pitman, the parts being in substantially the same position as shown in Fig. l. Fig. represents an end elevation showing the arrangement of the yoke supporting the head-block which forms the upper bearing of the power-shaft.

Similar numerals refer to similar parts throughout the several views.

1 represents a vertical power-shaft mounted on a bed-plate 2 and provided with the laterally-extending power-arms or trip-levers 3 and 11, having antifriction-rollers 5 and 6 in their ends. These parts are of the usual construction and arranged to be operated in the usual way by means of a horse-lever mounted on the power-shaft, which being familiar and common to this class of hay-presses is not shown. Y

7 represents the pitman, having mounted upon its vibrating end a pitman-head 8, pro- Vided at its end with a pocket 9 to receive the trip-lever roller and having a convex face 10, forming a hump 11 upon its inner side, over which the trip-lever roller travels as the pitman advances upon its instroke. The vibrating end of the pitman in its path and movement is controlled by a toggle device consisting of the arms l2, pivotally connected with the pitman, and the arms 12, the upper one of which is pivotally connected with the headblock 18 and the lower one pivotally mounted upon the bed-plate 2, said arms 12 and 12LL being hinged together at 14, a sleeve l5a being provided at the knee of the toggle thus formed, as shown in Fig. 3. The arrangement and pivotal relation of said toggle-arms are such that when, as shown in Fig. 2, the pitman is at the extremity of its outstroke the knee of the toggle will lie in the path of the trip-lever arms and as the trip-lever advances as one trip-lever roller engages the side of the pitman the opposite roller will engage the knee of the toggle and operate the pitman at the beginning and during the early part of the instroke,

the engagement of said trip-lever roller with the knee of the toggle continuing until the opposite trip-lever roller is seated in the pocket at the end of the pitman, as shown in heavy lines in Fig. 2, the toggle-arms acting to draw the pitman into position as the trip-lever roller passes down the inclined face of the pitman and into the pocket.

Upon a bed-plate 15, mounted upon the reach 16, is pivotally mounted a swinging or oscillating brake-beam 17, extending under and supporting the vibrating end of the pitman and upon 'which the pitman rides in making its in and out stroke, a stud 18 being provided on the outer extremity of said beam to limit the lateral movement of the pitman. Upon the pin 19, on which said brake-beam is pivoted, is mounted a tension-spring 20, the tension of which may be adj usted by the nut 21, bearing upon the cap 22, and the meeting or bearing faces of the brake-beam and said bedplate are at an inclination to the horizontal,

IOO

I is so arranged as to engage said brake-beam and carry it back to the position shown in Fig. 1 at full instroke. By reason of said inclined faces the force required to move said brake-beam will not appreciably interfere with the full force of the instroke.

It very frequently happens that when the instroke is made, for various reasons within the knowledge of those familial' with the operations of a hay-press, the plunger will stick in the baling-chainber and the pitman will not rebound, thus causing delay and serious inconvenience. To obviate this diiicultya tripping-arm'25 is mounted upon said brakebeam and extends into the path traversed by the trip-lever, so that when the pitman is released from the trip-lever roller, if the rebound does not at once take place, as the trip-lever advances it comes in contactwith said tripping-arm and turns said brak e-b'eam, which by its engagement with said extension 24 acts upon the pitman to release the plunger, when under the pull of the usual ten# sion-spring 26 the rebound will take place. The importance of this feature in securing the immediate rebound of the pitman will be apparent to any one experienced in the operation of a hay-press.

It will be observed that, as shown in dotted lines in Fig. 2, as the pitman reaches the limit of' its rebound the trip-lever roller is still some distance from the side of the pitman, this distance represent-ing about a ten-foot walk for the horses on the circle of a twelve-foot horse-lever between the end of the rebound and the beginning of the insti-oke of the pitman'. By this arrangement to obtain such interval an important advantageisl gained in` that, as is well known, in the usual construction and operation of a hay-press the inter'- val between the rebound and the beginning of the instroke is so short that the person feed-ing the press is not given time to properly introduce a charge of hay into the balingchamber in advance of theA plunger. With the arrangement and operationv here set out such an interval is gained that the press may be properly fed, while when theA trip-lever roll comes into engagement with the side of the pitman bythe accelerated movement given to the pitman'at the beginning of the instroke by the other trip-lever roller acting through the toggle-arms no time is lost in gaining such interval, and, furthermore, by the arrangement and construction here set out a longer stroke by some eleven inches is'given to the pitman than heretofore obtained, and by rea-y son of such longer stroke of the pitman a correspondingly-longer feed-opening to the baling-chamber is obtained, thereby verygreatly increasing the capacity of the press.

27 represents a stop-block arranged to limit the lateral movement of the pitman and elfect the release of the pitman from the trip-lever atthe end of the instroke.

As shown in Fig. 3, the head-block 13 is formed in two parts, to the rear one of which the reach-rod 28, extending to and'connecting the head-block with the baling-case, is secured. The connection of the reach-rod with the baling-case being a familiar construction in this'type of presses is not shown. Said two parts of the head-block are secured together upon the power-shaft by boltsf29, upon which are mounted 'tension-springs 30, soarranged that by the longitudinal strain upon the reach-rod in operating the pitman the two parts of said head-block will be drawn apart andi the springs 30 compressed, and when at the end of the instrole the trip-lever is released and the'strain upon the reachrod relieved the expansion o-f said springs will close said parts together upon the power- Shaft,` forming a brake which will equalize the draft and' relieve the shock upon the horses incident to the sudden release of the triplever. A yoke 31 is mounted upon the bed-plate 2 and secured by the bolts 29' upon the head-block to support the head-block and give stability to the power-shaft.

Having thus fully described my improvements and the manner inwhich they operate, what I claim as m-y in`vention and desi-re to secure by Letters Patent, is-

l. In a baling-press having a reach connecting the ba-linvg-case with the power end ot' the press, the combination with a bed-plate mounted on said reach, a brake-beamI pivotally mounted upon said bed-plate and operating upon inclined contiguous faces on said bedplate and brakebeam, and a tensionspring bearing upon said' brake-beam, of a pitman, ablock on the under side of the pitrnan tothe rear of said brake-beam and an extension on the under side of the pitman in advance of said brake -lheain, arranged in such manner that the re'ciprocaiions of the pitman will operate said brakebeam, substantially asset forth.
