PLOW-CLAEVIS.

SPECIFICATION forming part of Letters Patent No. 285,962, dated ctober 2, 1883.

Application tiled February 1, 1853. (No model.)

To all whom it may concern:

Be it known that I, Boson L. BRACKEN, a

citizen of the United States ol' America, re-

siding at Dawson, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Plow-Olevises; and I do hereby 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 letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to a clevis for connecting whiflietrees to plow-beams, singletrees to double-trees, and for other purposes in which devices of this class are used.

The object of the invention is to provide a elevis which can be quicky and easily placed in position, is readily operated for hitching and nnhitching, and the parts of which are securely held in place when in use.

The invention consists in the novel construction and combination of parts,which will be hereinafter particularly described, and pointed out in the claim.

In the accompanying drawings, Figure MS a view in elevation of a clevis constructed aecording to my invention. Fig. 2 is an eleva tion at right angles to Fig. 1, and Fig. 3 is a perspective view of the two arms of the clevis separated from each other.

The elevis is composed of the two arms A A, detachably pivoted together by means of the pin B, projecting from the-arm A and passing through a suitable pin-hole in the arm A. From the pivotal point the arms are bent laterally, and then extend parallel to each other, to form the straps a a, which embrace the beam tree, or other article on which the pull of the clevis is to be exerted. The straps an are provided at their ends with holes for the passage of the screw-pin O, which also passes through an opening in the article held between 45 said straps. The opposite portion of the arm A from the strap is bent in a plane nearly at right angles to the bend of the strap, to form a hook, D, and the arm A is bent in a similar manner to form a finger, D, which meets the tip of the hook, to close it when the clevis is in use. The pivot-hole of the arm A has ,a groove, 0, formed at one side thereof, and the pivot-pin B has a key-stud, f, projecting laterally from one end thereof, and said pin is of such length that when the arms are pivoted together the key-studf will stand on the out side of the arm A.

In placing the parts together ortaking them apart the arms are held in such position that the key-stud f will pass through groove 0, and when the clevis is closed said stud is out oi. line with the groove, as shown in Fig. 2, and prevents the parts from becoming separated laterally at the pivotal point. For opening the clevis the pin 0 isremoved and the strap of the arm A,-being released, will fall to the position indicated in dotted lines, as shown in Fig. 2. 1

The operation of the invention requires no further explanation.

What I claim is In a clevis, the combination, with the arm A, bent to form the attaching strap and hook D, and provided with the pin B, having stud f, of the arm A, bent to form an attachingstrap and the finger D, and provided with a hole to receive said pin and a groove for the passage of said stud, and the screw-pin 0, arranged to pass through suitable apertures in the attaching straps, substantially as de scribed.

In testimony whereof I affix my signature in presence of two witnesses.
