Two stems having loops formed on their 

 outer and disks on their inner ends are placed 

 within a casting composed of two semi-cylin- 

 drical parts, the ends of which are contracted to 

 form interior shoulders, and springs of different 

 degrees of strength are placed around said 

 stems, between said shoulders and disks. 



Claim. 1. In a spring-clevis, the combina- 

 tion of the two stems A A', with eyes or loops 

 B B', and disks C C, and the springs D D', of 

 . different thicknesses and strength, all construct- 

 ed and arranged within an exterior casing, 

 substantially as and for the purposes herein 

 set forth. 



2. in a spring-clevis, the exterior casing 

 made of two semi-tubular or semi-cylindrical 

 parts, G G, having contracted ends to form 

 interior shoulders a a, and provided with out-

199,073. WILLIAM KINNEY, Belle- 



vue, Ohio. Clevises. Jan. 8, 1878. Filed 



Oct. 27, 1877. 



The body of the clevis is of the usual form 

 and construction. The hole in each end is 

 provided with a slot, and a corresponding stud 

 is formed on the lower end of the pin, and 

 the under side of the lower arm of the clevis 

 is recessed, so that the pin can turn half-way 

 round. When in this position a button pivo- 

 ted to the side of the head is turned down, 

 which keeps the pin from turning back. 



Claim. An improved clevis, in which the 



bow A has grooves a 1 formed in the inner side 

 of its pin-holes, and a shoulder a 1 , formed up- 

 on the outer side of its lower end, and in which 

 the pin B has a lug b\ upon the side of its 

 lower end, and a latch, b*, pivoted to, and a 

 shoulder, b 3 , formed upon its head, substan- 

 tially as herein shown and described.

Eau Claire, Wis. Plow-Clevises. Feb. 26, 

 1878. Filed Jan. 25, 1878. 



The arms of the horizontal clevis are rigid 

 with a socket which slides upon the plow-beam, 

 and is held by set-screws, which also pivot the 

 vertical clevis. Through the latter is passed a 

 bolt with eccentric bearings, which holds the 

 draft-link in a notch, or, by turning, allows 

 the draft to be vertically adjusted. The bolt 

 also passes through the horizontal clevis, and 

 adjusts the draft to or from land. 



Claim. An improved plow-clevis formed 

 by the combination of the sleeve B, the hori- 

 zontal clevis C, the vertical clevis E, and the 

 eccentric bolt or pin D with each other, sub- 

 stantially as herein shown and described.
