MILO D. BEACH, OF LITCHFIELD, CONNECTICUT.

HILLSIDE-PLOW.

SI ECIFIGATION forming part of Letters Patent No. 399,001, dated March 5, 1889.

Application filed November 16, 1888. erial No, 291,026. (No model.)

To all whom it may concern.-

Be it known that I, MILO D. BEACH, a citizen of the United States, residing at Litehfield, in the county of Litehfield and State of Connecticut, have invented certain new and useful Improvements in Hillside-Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to'plows; and it consists in certain improvements in swivel or hillside plows, as hereinafter set forth and claimed. In a separate application filed herewith I have described certain devices by means of which the j ointer or colter and the clevis of an iron-beam swivel-plow can be antomatically reversed by themovement of the duplex hook when the mold-board is reversed. In this application I propose to show how a similar result can be effected with a woodenbeam plow. I also show and describe an improvement in shifting handles, this latter being applicable to either wooden or metal beams.

In the drawings, Figure l is a side elevation, partly broken away, of a wooden-beam plow embodyiu g my improvements. Fig. 2 is a plan of the casting containing the bearing for the jointer or colter stem. Fig. 3 is a plan of the clevis end of the beam. Fig. l is an end view of the casting attached to the end of the plow-beam. Fig. 5 is a plan of the shifting handles, partly broken away. Fig. 6 is aplan of the bearing between the handles and the standard. Fig. 7 shows the boxes. Fig. 8 is a side elevation showing the journals. Fi 9 is a plan of the head for the adjustable cranlc pin. Fig. 10 a crosssection of the rack. Fig. 11 is a side view of a modification of the jointer-stem bearing. Figs. 12 and 13 show the double eccentric for this hearing.

The same reference-letters are used in all the figures.

The wooden beam A is provided with the standard A, attached to it in the. ordinary manner. in the under side of the beam is cut a longitudinal groove to receive the shaft B B, which runs from the rear end of the beam to a pointncar the clevis. It is provided with suitable attachments for reversing the position of the jointcr or colter and the clevis, as hereinafter explained. It receives its motion through a bevelgear, (l, secured to its rear end, with which meshes a curved rack, D, formed in or attached to the bar D, which unites the handles E. The duplex hook F, which locks the swivelin g mold-board in either of its positions, is pivoted to the bar D by the vertical bolt f. The handles can be shifted laterally to enable the plowman to walk in the furrow, and their movement from one side to the other rotates the shaft B and operates the jointer or colter and the clevis. The ends of the handles E are bolted to the two blocks G by means of the bolt c, which passes through a slot, a, in the web of the standard, and also through slots 9 in the blocks. Above and below the slot to are parallel slots a a, the material a between them being cylindrical. in shape. At each end of the blocks G isa semicircular bearing formed between two projecting jaws, g, which are adapted to enter the slots a a, and thereby receive the journals a in their bearings. The jaws on the two blocks abut, shown in Fig. 6, and the bolt 6 holds them firmly together. Thebar D, to which the handles are fastened, has a semicircular groove, (1, in its front edge below the rack D. The groove fits a rounded flange, A projecting rearwardly from the standard A, so that the bar I) can slide laterally on the flange A The handles are therefore supported on the journals o and the flange A By adjusting the bolt 6 up or down in the slots a and gthe front ends of the handles will be raised or lowered, the flange A serving as the fulcrumon which the handles move. This permits the rear ends of the handles to be adjusted vertically to suit the plowman without interfering with their 9 capacity for shifting laterally. In front of the standard A there is bolted to the under side of the beam a casting, H, which contains a tubular bearing, H, for the stem I of the jointer or eolter. This casting has a baseplate, 71, provided with perforated ears 71.,to

receive the bolts, and a rear extension, 71 to give it sufficient bearing against the beam. The tubular bearing H has a hollow rib, 7L3, projecting from its front, to receive theupper part of the blade of the colter, as fully set forth in my other application aforesaid. A brace, h, runs from the lower end of the tubular bearing back to the rear extension, 72 of the base-plate.

The beam A above the tubular bearing is recessed out to receive the double eccentric J which has at each end a hub containing a square socket to fit the squared ends of the shaft B B. The hubs are joined by the short straight cylindrical shaft J, whose axial line crosses that of the shaft at an angle about midway between the hubs at the point where it is intersected by the axis of the stem 1. It thus constitutes a double crank or double eccentric, and by engaging wit-h the diametrical slot in the top of the jointer or colter stem it operates to oscillate said stem on its axis when the shaft 13 B is rotated. The casting H is provided with a pocket, It, into which the tubular bearing H opens, and which,taken in connection with the recess in the beam A, forms a chamber, in which the eccentric J can revolve.

The clevis end of the beam A is protected and strengthened by a box-shaped casting, K,,having a top and bottom and a front end. Integral with the bottom and end is an open cylindrical tube, 7c, which forms a bearing for the stem L. The casting K is secured to the beam by suitable bolts, as shown. In the inner end of the stem is a square cavity, into which fits the squared end of the shaft B. The front edge of the head L is curved and is provided with a T-shaped flange, Z, formed by a groove, Z, cut in each face parallel with the front edge. A dog, M, having a setscrew, m, slides on the flange Z and is provided with a nose or pin, M, engaging with a vertical groove in the inside of the clevis O. The arms 0 of the clcvis are hooked to engage with the headed studs L projecting from the top and bottom of the casting K. The hooks are open, as shown, to permit the clevis to be disengaged from the studs when swung around at right angles to the beam.

The operation of the head L, the adj ustable dog M, the clevis O, and the clevis-hook P are the same as described in my other application and need not be detailed here. The top and bottom of the casing K have lugs 7i formed thereon, between which are held the standards Q. of the wheel.

Figs. 5 and 8 show how the shifting handles can be applied to a plow similar to that shown .in my other application, and having an upwardly-extending shaft, B stepped in a bearing, a, on the standard. The connection of the duplex hook and its axially-yielding bolt is the same as set forth in that application.

Figs. 11, 1:2, and 13 show a mode of forming the bearing for the jointer or colter stem in a straightinetal beam. The bearing is cast integral with the beam, in the web of which is formed an opening, A to permit the eccentric J to revolve. The stem of the j ointer or colter has a bearin g above the opening A, and the upper and lower ends of the slot through it are indicated by dotted lines in Fig. 11. In order to get the eccentric J into place, its socket j and the part j are made of the same width as the diameter of the shaft, so that it can be passed through the narrow slot in the stem, the latter being turned until its slot stands transversely to the beam. 'When the shoulders of the cylindrical hub j strike the stem, it is turned back to bring the hub into line with the bearing A, into which it is slid. The shaft B can then be slipped into the socket j and secured thereto.

Instead of using shifting handles with the plow shown in Fig. 1', I may use stationary handles, and operate the bevelgear C by means of a sector-gear attached to the hub of a duplex hook, as shown and described in my other apylicat-ion.
