JACOB R. GRIFFITH, OF KANSAS CITY, MISSOURI.

.BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 568,846, dated October 6, 1896. Application filed August 20,1895. Serial No. 559,986. (No model.)

I 0 aZZ whom it may concern:

Be it known that I, JACOB R. GRIFFITH, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Baling-Presses, of

which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in hay-presses.

It relates more particularly to the class of hay-presses in which the exit end of the baling-chamber is contractible. It relates, further, to the class of hay-presses in which a rebounding pitman, connected to a follower operatin g in the balin g-chamber, is reciprocated by means of a double-armed lever revolved by suitable power, in combination with a spring tension operating upon the pitman.

The object of my invention is to provide a novel and efficient mechanism for contracting or expanding the exit end of the baling-chamber; to provide a simple and effective tucker connected with the baling-chamber, com prisin g an apron pivoted within the baling-chamher and a pivoted platform mounted upon the baling-chamber and so connected with the said apron as to depress the free end of the apron when the follower has been withdrawn for a charge to be placed in the baling-chamher; to provide a novel retaining mechanism combined with bracing for the baling-chamher; to provide an improved bed-plate having fixed guides for guiding the vibratory end of the pitman, together with means connected with the bed-plate for locking the pitman at the end of its stroke and means for checking the rebound of the pitman after each compression, and to provide certain new and improved features of construction and com Fig. 3 represents a plan view of the bedplate and the forward end of the pitman, togetherwith the double-armed lever which operates the pitman. In this view the pitman is shown in its locked position with one of the arms of the operating-lever about to engage the cam on the pitman-head. In this view the normal position of the spring-actuated roller for checking the rebound of the pitman is shown in dotted lines. Fig. t represents a longitudinal vertical sectional view of the tucker and a portion of the balingchamber, In this view the position of the parts of the tucker during compression of the hay is shown in dotted lines. The solid lines represent the position of the parts after the follower has been withdrawn. Fig. 5 represents a front elevation of the hay-press with the remote parts removed for greater clearness. Fig. 6 represents an elevation view of the retaining mechanism, bracing mechanism, tool-box and tucker, and apertion of the baliiigcliamber. Fig. 7 represents a vertical sectional view taken on the dotted line J y of Fig. 6, the right-hand side of the baling-chai'nber and tool-box being broken away. Fig. 8 represents a side eleva tion of the bed-plate, a portion being shown broken away, so as to show the construction of the checkingmechanism. Fig.9 represents a plan view of one of the retaining levers, the U -shaped bracing-rod and the side of the baling-chamber being shown in section. Fig. 10 represents a perspective view of the plate. Fig. 11 represents a rear view of the balingchamber and tension mechanism, the extreme ends of the sides of the baling-chamher being cut away. Fig. 12 represents a side elevation view of one of the retaininglevers. Fig. 13 represents a broken-away portion of the right end-of the bed-plate -in elevation and section and the spring checking mechanism in elevation. Fig. 14 represents a perspective view of the plate.

Similar letters and numerals of reference indicate similar parts throughout the several views. v

A indicates the forward axle, B the rear axle, and O the wheels, upon which the press is supported.

D indicates the baling-chamber.

E indicates the pitman, to the rear end of which is secured a follower or head-block F.

G indicates a horizontal bed-plate connected at its rearend by means of the two tubes H, forming a reach to the forward end of the billing-chamber.

. ends of which are secured to the sides of the balingchamber. Secured upon the front axle is a casting N, to which the forward end of the base-plate G is pivotally connected and which serves as a fifth-wheel for the press. A vertical shaft 0 has its lower end pivoted in the bed-plate and its upper end pivoted in the collar J.

To the upper end of the shaft 0 is secured a crosshead P, to one end of which is secured the rear end of a tongue Q, and to the opposite end of which is secured the rear cnd of a brace-rod 1-1, the forward end of which is secured to the forward end of the tongue. Secured to the shaft 0, between the arch l and the bed-plate G, is a horizontal doublearlned lever S, the ends of which are provided with friction -rollers T, adapted when the shaft 0 is revolved to operate against a headblock secured at the forward end of the pitman, as indicated by U.

V indicates a hopper upon the top of the baling-chamber, through which the hay is fed to the bailing-chamber.

1 indicates the upper and lower frames of the baling-chamber, consisting of an angleiron at each corner of the baling-ehamber. 2 and 3 indicate, respectively, the upper and lower plates of the baling'chamber. These plates are narrower than the inner width of the baling-chamber, so as to admit of the rear end of the balingchamber being contracted by the tension mechanism.

Secured upon the upper side of the balingchamber to the rear of the hopper is a cast tool-box l, which is provided with a trans verse partition 5. To the rear side of the toolbox is pivoted a cover (3, which serves also as a platform for the man who is feeding the hating-chamber and as an operatinglever for depressing theapron 7, which is an obliquelyinclined plate,the forward upper end of which is pivoted in the baling-chamber just below the forward edge of the tool-box. A lug 8, upon the forward edge of the apron 7, is adaptedto strike against the lowerside of the tool-box and prevents the apron from dropping too low at its rear end. A plate 9 is titted between the apron 7 and the cover (5, the upper and lower edges resting, respectively, in transverse grooves, one in the lower side of the cover and the other in the upper side of the apron. A slot extending transversely across the bottom of the tool-box permits movement therethrough of the plate 9 when the tucker is operated.

Each side of the tool-box at or near its forward end is provided with a projection 10, which is provided with two vertical openings, through which extend the two arms of a U- shaped strap 11, the lower end of which embraces the rear axle and the two upper ends being provided with screw-threads, to which are fitted the nuts 12. Between the lower angle-irons l and the rear axle on each side of the baling-chaniber is acasting 13, which is provided with twovertical openings, through which pass the arms of the strap or stirrup 11. Upon each side of the balingchamber are located three retaining-levers 14, the rear inwardly-curved ends of which extend through openings 15 in the side of the baling-chamber. The retaining-levers 14 are disposed one above the other on each side of the baling-chamber, the upper lever being pivoted between a casting us, located below the projection 10 of the tool-box, and a casting 17, lo 'atcd below the lever let. The middle lever is pivoted between the casting l7 and a similar casting 18. The lower lever is pivoted between the casting lb and the casting 13. The upper and lower side of each retaining'lever is provided with a vertical projection 19, cylindrical in form, which enters a vertical opening in the adjacent casting. Each side of the castings 17, lo, and 18 is provided with a vertical groove, (indicated by 20,) in which lie the arms of the strap 11.

The forward end of each of the retaining arms or levers 14- is provided with a vertical disk, from the center of which inwardly extends a cylindrical projection 21, upon which is mounted a coil-spring 22, the outer end of which rests against the disk-shaped end of the retaining-lever and the inner end against the side of the baling-chamber. The tension of these coil-springs is such as to normally keep the opposite end of the retaining-lever within the balii'ig-chamber and thus preventing the hay from expanding after compression. Each of the castings l7 and 18 is pro vided with a horizontal outwardly-extending projection 23, the outer end of which is groovedvertically. A vertical rod 24:, secured at its lower end to the casting 13 and at its upper end to the projection 10, is bent outwardly, so as to lie in the grooves in the outer ends of the projections 23.

I will now describe the mechanism for contracting the exit end of the baling-chambcr.

Referring to Figs. 1, 2, and ll, 25 indicates two horizontal plates, one above and one located below the baling-chamher and extending transversely across it. A vertical rod 26 has its upper and its lower ends pivoted in vertical openings in the

castings

27 and 28, which are secured, respectively, to the upper and the lower angle-irons 1 on one side of the baling-clmmber. The plates 2-5 are secured one at each end of the vertical rod 26. The free ends of the plates 25 are pivotally connected to the ends, respectively, of a vertical bar 29, located upon the side of the balingchamber opposite to the rod 26. Revoluble upon the bar 29, one below the upper plate 25 and the other above the lower plate 25, are two friction-rollers 30.

Forward of the bar 29 and farther removed from the baling-chamber is avertical bar 31, the ends of which are pivoted in vertical openings of two brackets 32, which are secured to the side of the baling-chamber, one to the upper angle-iron 1 and one to the lower angle-iron. Each bracket 32 is provided with a convex-faced cam at its outer edge, over which the roller 30 is adapted to travel when the plates are swung on their pivoted support. A horizontal rod 33 is secured at its rear end to the bar 29 and passes from thence through a horizontal opening in an enlarged central part of the bar 31. The forward end of the rod 33 is screw-threaded and has fitted to its screw-threaded end a hand-wheel 34. Mounted upon the rod 33, between the hand-wheel 34 and the bar31, is a stiff coil-spring 35. By revolving the handwheel 34 in the proper direction the rollers are made to travel over the cam-surface of the brackets 32, thus drawing the sides of the baling-charuber closer together or forcing them apart, depending on whether the plates 25 are moved forward or backward.

The following is a description of the guiding mechanism for the vibratory end of the pitman:

The head-block U is a cylindrical-formed casting provided with a longitudinal opening, into which the forward end of the pilnian is movably fitted. To the under side of the head-block U is revolubly secured a frictionroller 36, adapted to travel between the guiding-

flanges

37, 38, and 39 upon the upper face of the bed-plate G. Upon the left side of the head-block is a beveled cam 40, adapted to receive the impact of the rollers T, upon the double-armed lever S, when the pitman is in the position shown in Fig. 3. To the extreme front end of the head-block U is vertically dovetailed thereto a hardened casting 41, the front end of which is curved so as to be adapted to receive the rollers T. The headblock U is held on the pitman by means of a rod 42, the forward end of which is secured to the head-block and the rear end of which passes around a horizontal plank 43, which lies against and parallel to the pitman, to the rearward portion of the pitman to which it is secured.

The flange-guide 37 is located upon the right-hand side of the bed-plate G as viewed from the front of the machine, and is curved forwardly and to the right until a point near the front end of the bed-plate is reached, at which point it curves toward the left. The guiding-flange 38 is located at the rear end of the bed-plate and lies parallel to the flangeguide 37. The flange-guide 39 is located at the forward end of the bed-plate and has a portion of its length parallel to the curved forward end of the guide 37, and at its extreme forward end is provided with a concaved front side adapted to receive and hold the roller 36 when the pitman is in the position illustrated in Fig. 3.

The forward end of the bed-plate on its under side is provided with a semicylindrical projection 44, which lies in a vertical plane that is obliquely inclined to the longitudinal center of the pitlnan when the pitrnan is in the rearward position, as shown in Figs. 1 and 2. The semicylindrical projection 44 is grooved for a portion of its length from the front end in order to permit the movement therein of a right-angled bar 45, the vertical leg of which is adapted to slide in a slot cut vertically through the bed-plate and joining the opening in the projection 44. The said slot is indicated by 46.

To the vertical leg of the right-angled bar 45, at its upper end, is pivoted a horizontal roller 47, the under side of which moves along the upper side of the bed-plate. The springactuated roller 47 serves not only as a buffer for the free end of the pitinan at the forward end of its stroke, but also forces the roller 36 into the seat in the front end of the flange 39, and thus serves as a locking device for holding the free end of the pitman in the said seat.

Secured within a longitudinal opening in the horizontal leg of the an gle-bar is a horizontal rod 48, which extends rearwardly and to the right and passes through an opening, to which it is movably fitted in the. rear end of the projection 44. At the rear end of the rod 48 is secured the forward end of a coilspring 49, the rear end of which is secured to a projection 50 on the underside ofv the bedplate G. Mounted upon the rod 48, to the rear of the projection 44, is a coil-spring 51, the rear end of which rests against a plate 52, secured upon the rod 48 near its rear end. When the rod 48 is in the rear posit-ion, (shown in Fig. 13,) the coitspring 51 does not bear upon the rear end of the projection 44, and it does not operate until the roller is forced forward by the striking against the roller 47 of the roller 36, that is secured to the under side of the head-block U. At such a time it relieves the strain upon the relatively light spring 49 and prevents the pitman from moving too far forward, and, in connection with the spring 49, forces the roller on the headblock U into the concaved front end of the guide 39. In order to assist the hay in forcing the pitman to its forward position, a coilspring 53 has its forward end secured to a clip 54, which is securedto the connectingrod K near its forward end, the rear end of the said spring being secured to the plank 43.

My invention is operated as follows: The shaft 0 is made to revolve by means ofv power applied to the tongue Q, thus revolving the double-armed lever S, which in revolving forces the forward end of the pitman to the right through the intermediacy of the rollers T comingin contact with the cam 40 on the head-block U at the front end of the pitman. After the roller 36 has passed to the right and out of the concaved front end of theguide 39 the tension of the

springs

49 and 51,'operating the angle-bar l5, forces the roller 47 rearwardly, and this in turn forces the pitman rearwardly by pushing against the roller 36 on the head-block U. In the meantime the roller '1 runs along the inclined surface of the cam 4L0 and finally into the concaved front of the chilled casting -.tl, at which time the power of the lever S is applied against the pitman, forcing it rearwardly, the roller 36 following the guide-flange 37 and causing the pitman to assume the position shown in Figs. 1 and 2. \Vhcn the pitman has reached the limit of its backward movement, the roller '1 is disengaged and the pitman springs forward, due both to the tension of the hay that was compressed during the rearward movement of the pitman and to the tension of the spring 5-3. During the time that the pitman and follower are in the forward position the man standing on the platform 0 fills the forward part of the bailing-chamber with hay through the hopper V. The rearward movement of the follower forces the hay backward into the rear portion of the baling-chamber, past the retaining-arms 14, which are forced outward at their inwardly-projecting ends. As soon as the follower on the pitman recedes the retaining-levers llspring into the chamher and prevent the hay that has been compressed from springing past them. At the same time the weight of the man who is feedin g and standing on the plat-form O, which was raised at its free end, due to the hay pressing against the swinging apron 7, causes the raised end of the platform to lower, and through the intermediacy of the plate f) forein g the apron downward at its free end, and thus tucking down the hay under the apron that otherwise would give the bale a ragged appearance. In case it is desired to make the bales more solid, the hand-wheel is turned in a direction such as will force the rod forward, and thus drawing the rollers 30 forward up the inclined face of the brackets and drawing the two sides of the chamber toward each other through the intervention of the plates 25. The spring 35 is provided on the'rod 33 in order to give a certain amount of elasticity to the compressible end of the billing-chamber. After the roller '1 on the lever S has released the pitman it springs forward, the roller 36 following the guide-

flanges

37, 3S, and 39. At the forward end of the bed-plate the roller 36 strikes against the roller 47, which is forced outward against the tension of the spring 49 until the compression-spring 51 comes in contact with the rear end of the projection H, relieving the spring 49 and causing the pitn'ian-roller 36 to slide into the coneavcd face of the guide 39, in which position it rests until the lever S, in revolving, brings one of the rollers T in contact with the cam -10, at which time the forward end of the pitman is forced to the right as viewed from the front, as hereinbefore described.

Various departures in construction maybe made from what I have described while still remaining within the scope of my invention. For instance, the shaft 0, the lever S, and the cross-head P maybe cast in one piece, if found desirable. The conformation of the guides and the manner of applying them to the bed-plate may be varied to suit convenience or pleasure, and other modifications may be made without departing from the spirit of my invention.
