QPECIPICATION forming part of Letters Patent No. 389,999, dated September 25, 1888.

Application filed March 24, 1888. Serial No. 268,352. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAsoN DILBIRD BIN- FORD, a citizen of the United States, residing at McGlelland, in the county of Isle of WVight and State of Virginia, have invented a new and useful ImprovementinPlow-Olevises,of which the following is a specification.

The invention relates to improvements in clevises for plows and other farming-vehicles; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the drawings, and pointed out in the appended claim.

In the drawings, Figure 1 represents a perspective view of a clevis embodying the invention attached to a plow. Fig. 2 is a view of the clevis detached and with the retaining-pin withdrawn. Fig. 3 represents a longitudinal sectional view of the clevis with the said pins and bolts in place, showing the whiffletree attached.

Referring to the drawings by letter, A designates the plow-beam of the plow, and B the clevis attached thereto, and which is constructed as follows:

C is a vertical metal plate having at its ends the forwardly-projecting arms 0 c, and centrally the similar arm,c The highest arm, a, is provided with an angular opening, 0, the arms 0 0 having circular openings which are vertically aligned with the opening 0 D is a cylindrical retaining-pin that fits into the said openings, having its top portion made angular for a short distance, as shown, to fit into the opening 0 The saidpin is provided with a head, r1, consisting of a metal plate resting on the arm 0, and a fiat metal projection, d, rising therefrom to permit the pin to be easily raised thereby in its seat.

E E are projections standing from the front surface of the plate 0, and forming, with the retaining-pin, which they nearly touch, the open spaces 6, to receive the ring of an ordinary whiffletree, e, as shown in Fig. 3.

plate 0 at equal distances from the upper and lower ends thereof, respectively, the said plates being strengthened and braced upon the plate 0 by the vertical ribs ff, that connect them respectively with the upper and lower arms of the plate 0. The plates F F are provided with the bolt-holes G g, respectively,and H H designate the bolts passed through said holes and provided with the securing-nuts h.

The plow-beam is placed between the plates F F, with its end firmly abutting against the plate 0, so that its front is bound at the end and above and below with metal, and the bolt-s are passed through the described openings and through registering-openings in the beam.

The clevis is securely fastened to the plowbeam, so that it cannot become loose, and the wear of the parts is reduced to a minimum.

The retaining-pin can be readily raised to remove, change, raise, or lower the whiffletree, and if broken another can be easily fitted in its place.

Having described my invention, I claim- The combination, with a plow-beam, of the clevis comprising the vertical plate O,pr0vided with the forwardly-projecting arms a c cfland having the projections E E on the front side of the plate 0, the plates projecting from the rear side of the plate 0, and the ribsff, connecting the same with the upper and lower ends of the plate 0, and the bolt inserted JASON DILBIRD BINFORD.
