UNITED STATES PATENT OFFICE.
INTERLOCKING CLEVIS Specification of Letters Patent.
Patented Jan. 9, 1906.
Application filed September 1l, 1905. Serial No. 277,974.
To all whom t T11/ty concern:
YBe it known that I, NiLs M. LIEN, a citizen of the United States, residing at Langhei, in the county of Pope and State of Minnesota, have invented certain new and useful' Improvements in Interlocking Clevises; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has for its object to provide an improved clevis in which the pin and the yoke thereof interlock with each other in such manner that they cannot become accidentally separated.
To the above end the invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claim.
The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views. Y
Figure 1 is a view, chieiiy in side elevation with some parts sectioned showing the improved clevis. Fig. 2 is a horizontal section on'the line 002 002 of Fig. 1 looking upward.
Fig. 3 Ais a detail, principally in transverse vertical section with some parts in full, showing the upper portions of the pin and yoke; and Fig.^4 is a detail corresponding to Fig. 1, but illustrating a slightly-modified construction, some parts being broken away.
The numeral 1 indicatesthe yoke, and the numeral 2 the pin, of the clevis, which pin is adapted to be passed through seats formed in the prongs of the yoke. The pin 2 is provided at its upper end with a head 3 and with a shoulder 4, and a considerable distance below-the shoulder 4 it is provided with a laterally-projecting lock-lug 5. The upper prong of the yoke surrounding the pin-seat is, as shown, formed with a depressed seat 6, that affords a seat for a coiled spring 7 the upper end of which acts upon the shoulder 4 and tends to raise the pin. The pin-seat in the upper prong -of the yoke is formed with a laterally-projecting' vertically-extended longitudinal groove 8, through which the locklug 5 of the pin is adapted to be passed.
In the construction illustrated in Figs. 1, 2, and 3 the upper prong of the. yoke on its under surface is formed with a countersunk semicircular groove 9, that extends from the lower extremity of the longitudinal groove 8 concentric with .the aXis of the pin-seat and terminates at its other extremity in an upwardly-extended lock-notch 10. With this construction, as is evident, when the lock-lug 5 of the pin is turned into a line with the longitudinal groove 8 the said pin may be withdrawn from working position or placed in working position. When the-bolt is turned so that its lock-lug 5 engages the lock-notch 10, the spring 7 pressing upward on the pin holds the said lug engaged with said locknotch, and thereby prevents accidental sepa-l ration of the pin from the yoke. To disengage the pin from the yoke requires a slight downward movement of the pin against ythe tension of said spring, so as to carry the locklug 5 out of engagement with the lock-notch 10. This being done, the lock-lug may of course be turned into alinementv with the longitudinal groove 8, and the pin may then be removed.
The action of the device shown in Fig. 4 is substantially the same as that above described. In the former construction, however, in view of the countersunk seat-groove 9 the lock-lug 5 in moving pivotally from the lock-notch 10 to the longitudinal groove 8 is not necessarily forced downward below the under surface of the upper prong of the yoke, while in the construction shown in Fig. 4 the said lug must be forced below the under surface of the upper prong of said yoke. The former construction, therefore, permits use of an evener or other object, but closely fits the upper and lower prongs of the yoke.
What I claim, and desire to secure by Let ters Patent of the United States, is as follows: The combination with an integrally-formed yoke 1, of a pin 2 fitting seats in the prongs thereof, one prong of said yoke having a longitudinal groove 8, lock-.notch 10 and countersunk segmental groove 9 connecting said groove 8 and lock-notch 10, and said pin 2 having a single projecting lock-lug 5 adapted to be passed through said grooves 8 and 9 and to be seated in said lock-notch 10, and a coiled spring surrounding said pin 2, reacting against the yoke of said pin and normally holding said lock-lug 5 engaged with saidv lock-notch 10, substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
