BALING-PRESSFOR HAY, 80C.

SPECIFICATION forming part of Letters Patent No. 433,857, dated August 5, 1890.

Application filed october 1889.

To all whom it may concern:

Be it known that I, RUFUS GREENLIEF ELLSWORTH, a citizen of the United States, and a resident of Northcott, in the county of Anderson and State of Kansas, have invented.

certain new and useful Improvements in Baling-Presses for Hay, &c.; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appert'ains to make and use the same.

My invention relates to baling-presses and it consists, essentially,'in providing a. construction which will not only possess the advantage of effecting a most thorough pressing of the loose hay, whereby greater compactness is attained, but also in providing a' device by means of which the side feed-door is automatically opened and closed on each reciprocation of the follower; and with these and other objects in view it consists in the improved construction and combination of parts, as hereinafter more fully pointed out and described.

In the accompanying drawings, forming part of this specification, Figure l is aperspective View of my device complete, showing the door in an open position. Fig. 2 is an enlarged detail view of the door, showing the spring-catch thereon. Fig. 3 is a horizontal sectional view of the press. Fig. 4. is a longitudinal vertical sectional View of the Fig. 5 is an end view,in perspective, showing the sweep removed; and Fig. 6 is a perspective view of the under side of the sweep. I

Similar letters of reference are used to designate corresponding parts throughout the entire specification and several views of the drawings.

Referring to the drawings, the letter A indicates the frame or body of'my improved press mounted upon suitablewheels B B. This body or frame is divided into a pressbox 0, provided with a suitableside feedopening 0 and a rear bale-chamber D. The bottom of the press-box is extended forwardly and provided with a bifurcated end E. A shaft F is journaled in bearings upon this extended end, said shaft carrying a bellcrank G, one of the members G thereof be- Serial No. 325,668. (No model.)

ing connected to a follower or plunger H, which slides within the press-box, by means of arms or links g g, the inner ends of said arms being pivoted within a socket g in the follower. One of the arms formed by the bifurcated end E is provided with anend slot or recess I, and centrally pivoted therein is a vertical arm J, having the upper end beveled inwardlyand adapted to engage a beveled shoulder orlug 9 upon one of the links g.

A door L is suitably journaled upon a vertical shaft M, located at one end of the feedopening 0, said shaft being extended downwardly and terminating in a crank m. To this crank is attached a rod N, the other end of said rod being secured to the lower end of the vertical arm J. The crank m has also secured thereto a spring 0, which extends rearwardly, and is secured to the under side of the body of the press.

Suitably pivoted to one of the side pieces of the frame is a horizontal rod P, the inner end thereof having secured thereto a chain or equivalent Q, while the opposite end of saidv chain is attached to the follower or plunger.

A similar chain R is secured to the outer end of the pivoted horizontal arm, and the rear end of said chain is secured to a spring catch S, located upon the outer side of the door L.

outer end of said arm is thrown forward, thus causing the chain secured to this end to be drawn taut and consequently releasing the spring-bolt, the retraction of the spring 0 at the same time throwing the door open by acting upon the crank m and forcing the upper end of the vertical arm J ;forward by means of the rod N, connecting the lower end of the same with said crank. As will appearmore fully farther on,-it will be seen that the opening of the door is effected only after the follower has reached its innermost limit, so that the door remains closed while the follower is moving inward and pressing the hay, so as 8c This spring bolt or catch is adapted to passes its normal position.

to obviate all danger of the latter being forced out, which would be the case if there were no means provided for closing the door during the operation of pressing. As stated, however, the chain connecting the inner end of the horizontal pivoted arm is only drawn taut enough to effect the opening of the door when the follower has reached its extreme inner limit. After this point is reached the follower of course rebounds, and when it reaches its extreme forward or outer limit the beveled lug or shoulder on one of the connectinglinks hereof engages the upper end of the vertical arm J and carries the same rearward, thus forcing the lower end forward, or in opposite direction. As the lower end is connected to the crank of the door by means of the rod N, the latter necessarily turns the crank of the shaft upon which the door is mounted, and, overcoming the resiliency of the spring, forces the door inward. Of course after the upper end of the vertical arm J is carried forward a certain distance it becomes disengaged from the shoulder or lug of the bell-crank links or arms, and again resumes This operation is automatically repeated as the follower is reciprocated, providing a convenient means for the opening and closing of the door at the most desirable moments-that is to say, opening the door when the follower is on its outward stroke, so that the hay may be inserted, and closing the door when the follower begins to press against the hay, thus preventing the same from being forced out of the feed-opening.

Running through a suitable keeper U, secured to a rod V, is a rope or chain W, which connects at its inner or rear end with the lower member or arm G of the bell-crank lever. In order to obtain greater strength and security, I connect the ends of the upper and lower members of the bell-crank by means of a metallic strip X. Secured to the inner end of the rod V and extending beneath the bifurcated bottom piece of the press-box is a metallic spring-plate Y, while near the forward end of said rod is secureda crossbar Z.

The letter A indicates a segmental armguide, one end thereof being secured to the cross-bar Z, while the other end is secured to the forward end of the rod V, and is then in- "clined downwardly to a slight degree and turned over or bent, so as to form a pocket. (Indicated by the letter a.) An arm B is pivoted to the center of the cross-bar by means of a bolt 0, the other end of said arm being adapted to. rest upon and be guided by the segmental guide-arm. The rope or chain W, after passing through the keeper U, is then passed through a keeper D, secured to the cross-piece Z, and is finally secured to the end of the pivoted arm B. Pivoted above the arm B is a sweep E, turning upon the bolt 0, upon which the arm is also pivoted. This sweep is provided with a cross-barF,located slightly to one side of the pivotal point, the

ends of said cross-bar, as well as the end of the sweep proper, being provided with depending bolts G which are designed to engage with the pivoted arm when the sweep is revolved. With each third throw of the sweep the arm 13 is carried in an arc of a circle through the medium of the depending bolts until it reaches the inclined or downwardlyextending pocket of the segmental arm-guide, when, by reason of coming in contact therewith, and owing to the inclination of the same, it is released from engagement with the bolt and is caused to return to its normal position by the pressure of. the metallic springplate Y, accelerated by the rebound of the hay after pressure upon the follower, causing the latter to move outward and slackening the tension of the chain W. This pressure of the spring-plate and rebound of the hay also causes 'the lower member of the bell crank to pass upwardly between the metallic arms or links 9 9, thus drawing the follower outward to its extreme limit until the shoulder or lug thereof engages with the beveled upper end of the vertical arm J. As the sweep is further revolved, the other depending bolts will likewise engage the pivoted arm in turn, thus providing for three inward and outward movements of the follower upon each revolution of the sweep. It will also be noticed that when either of the series of de-.

pending bolts engages the pivoted arm and causes the same to be carried forward the rope or chain connecting the same with the lower member of the bell-crank will be drawn taut, and, as the arm is carried still farther, the lower member of said bell-crank is drawn downward into the bifurcated end of the press-box, thus causing the inward movement of the follower or plunger within the pressboX. Of course the moment the pivoted arm is released and returns to its normal position the rope or chain is necessarily made slack, when the metallic spring-plate bearing upon the lower member of the bell-crank, as previously stated, forces the same upwardly, and consequently causes the outward movement of the follower.

My invention possesses the advantage of providing a full-circle sweep that is mounted without the necessity of bridging for the animal to pass over.

Having thus fully described my invention, what I claim as new, and desire to secure protection in by Letters Patent of the United 1 States, is-
