GEORGE E. CLAUDE, OF SHERBURN, MINNESOTA, A$SIGNOB 0F ONE-HALF TO JAMES C. CALDWELL, O15 LAKIEFIELD, M 'NNESO'IA.

CLEVIS.

Application filed December 17, 1919.

To all 207/0112 c'z may concern:

Be it known that l, Gnoiior: E. CLAUDE, a citizen of the United States, residing at Sherburn, in the county oi? lilartin and State of Minnesota, have invented certain new and useful Improvements in (.llevises, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in clevises, and it is an object of the invention to provide novel. and improved means whereby the pin coacting with the clevises may be effectively held in applied position.

Another object of the invention is to provide a novel and improved clevis including arms possessing a certain degree of inherent resiliency, and with which the pin coacts, and wherein said pin and one of the arms are provided with coacting means whereby the pin is maintained in applied position through the instrumentality 03f the resiliency of the arms.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved clevis whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view partly in elevation and partly in section illustrating a clevis constructed in accordance with an embodiment of my invention;

Fig. 2 is an elevational view of the pin detached, and

Fig. 3 is a fragmentary view in top plan of the lower arm of the clevis, as illustrated in Fig. 1.

As disclosed in the accompanying-drawings, my improved clevis C is substantially U shaped in form with the arms 1 normally substantially in parallelism, and which arms possess a certain degree of inherent resiliency. The free extremities of the arms 1 are provided with the openings or eyes 2, through which is adapted to extend the pin P.

Specification of Letters Patent.

flatented Feb. 8, 1921.

Serial No. 345,597.

The pin P includes a cylindrical shank, preferably of the same diameter throughout its length, and which is provided at one end portion with a head or enlargement The opposite end portion of the shank 8 is provided in its periphery with a spiral groove 5 extendin substantially half around the shank Che outer end oi the groove 5 is open at the end of the shank, and the inner end portion of said groove 5 is continued by a forwardly directed groove 6 disposed on an incline relative to the longitudinal axis oi the shank and in a direction away from the adjacent end of the groove 5. The wall of one of theeyes or openings 2 is provided with an inwardly directed rod or tit 7 of a size to readily engage within the groove 5 and the extension 6 thereof.

In practice the shank 3 is first inserted through the opening or eye 2 having an unobstructed bore, and within the second opening or eye 2 a distance sufficient to position the lug or tit 7 within the outer or open end portion of the spiral groove 5. Upon proper rotation of the shank 4 the lug or lit 7 travels inwardly of the groove 5, and which movement is permitted on account of the inherent resiliency possessed by the arms 1 of the olevis C. When the lug ortit 7 reaches the inner end of the spiral groove 5 the arms 1 of the clevis will spring outwardly or in a direction one from the other, whereby the lug or tit 7 is caused to seat within the extension groove 6. The resiliency of the arms 1 or the natural tendency of said arms to spring outwardly results in the pin P being effectively maintained or locked in applied position.

VVhen is desired to remove the pin P from applied position proper rotation of the pin 6 results in the lug or tit 7 to coact with a wall of the groove 6 to draw the arms 1 inwardly a distance suliicient to permit the lug or tit i" to return to the groove 5, and whereupon the pin P may be easily removed.

If necessary a wrench or other tool may he engaged with the head 5 of the pin to impart the initial rotary movement thereto when it is desired to remove the pin.

From the foregoing description it is thought to be obvious that a clevis con structed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be-obvious that my invention is susceptible of some change and modification Without departing from the principles and spirit thereof, and for this reason I do not Wish to be understood as limiting myself to the precise arrangement and formation'of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

' I claim:

In combination, a substantially U shaped clevis, the arms of Which being resilient, the free extremities of the arms being provided with openings, one of said arms being pro vided With a lug extending inwardly of its opening, and a pin insertible through the openings of the arms, said pin being provided With a spiral groove in its periphery, having one end opening at the end of the pin, the inner end portion of the groove terminating in an inclined closedextension dis 7 posed toward the free end of the pin, the lug of one of the arms moving inwardly of" the groove upon rotation of the pin in one direction, and automatically seating Within the extension of the groove by the resiliency of the arms of the clevis.

In testimony whereof I hereunto afiix my signature.

G. E. CLAUDE.
