Description

UNITED srArEs PATENT oEEroE.
No. 840,128. y
Specification of Letters Patent.
Patented Jan. 1, 1907.
Application filed October 3, 1906. Serial No. 337,222.
To all whom it may concern:
` Be it known that I, EDWIN J. J. GREGER- SON, a citizen of the United States, residing at Woodville, in the county of St, Croix and State of Wisconsin, have invented 'certain new and useful Improvements in Interlocking Clevises; and I do hereby declare the iollowing 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.
My invention has for its object to provide an improved interlocking clevis; and to this end it consists of the novel devices and conibinations of devices hereinafter described, and dened inthe claims.
The improved device is' illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.
Referring to the drawings, Figure 1 is a view in elevation with some parts broken away and some parts sectioned, showing the improved clevis. Fig. 2 is a plan view ofthe same. Fig. 3 is a horizontal section on the line :r3 :1:3 of Fig. 1, some parts being broken away. Fig. 4 is a vertical section on the line x4 m4 of Fig. 2, some parts being broken away and Fig. 5 is a vertical section on the line :v5 x5 of Fig. 2, some parts being broken away.
The body of the clevis, whichis indicated by the numeral 1, is provided in the ends of its prongs with seats that close iit a detachable clevis bolt or pin 2. The seat in theupper prong of the clevis is provided with a vertically-eXtended notch or lock-lug passage 3,
that opens into a segmental clearance-groove 4, formed in the upper prong of said yoke 1 and extending'outward from and concentric with the lower portion of the pin-seat of the said upper prong. The said segmental clearance-groove 4 lies directly under a segmental lock-shoulder 5.
On the upper surface of the upper prong of the yoke 1 is a cam-surface 6, that is formed with a lock-groove 7. Formed integral with or otherwise rigidly secured to the upper end of theclevis-bolt 2 is a spring lock-lever 8, the Jfree end of which is flattened to form a fingerpiece 9, the lower edge of which engages with the lock-groove? to hold the bolt 2 against accidental rotation. On the upper prong of thexyokewl is a guard-ilange 10, that extends along one side of said lever and protects the same in such manner that a heavy object falling on the clevis cannot break the said lever. The clevis-bolt 2, near its upper end, is provided with a radially-projecting lock-lug 11, that is adapted Vto be passed vertically ythrough the notch 3 and to be turned into the clearance 4 under the lock-shoulder 5.
As is evident, the bolt may be applied to the clevis or removed therefrom when, and only when7 its lock-lug 11 is turned into registration with thenotch 3. It is also evident that when the said lock-lug is turned under the lock-shoulder 5 and the end9 ofthe spring-lever 8 is engaged with the notch 7 of the surface 6 the said bolt will be securely interlockedto the body of the clevis. It is also evident that when desired the spring-lever 8 may be readily pressed out of engagement'with the notch 7 and turned into position for removal from the body of the clevis.
The device described, while simple and of small cost, is highly efficient for the purposes had in view.
What I claim is- 1. The combination with a clevis-yoke, of a clevis-bolt having interlocking engagement therewith under endwise and rotary movement, of a spring-lever applied to said bolt and having interlocking engagement with said clevis-yoke to hold said bolt in its interlocked position, substantially as described.
2. The combination with a clevis-yoke 1 having bolt-seats in its prongs, one of said prongs having adjacent to its bolt-seat a notch 3, segmental clearance 4 and lockshoulder 5, of a clevis-bolt 2 having a springlever 8 and lock-lug 11, which lock-lug 1s adapted to be inserted through said notch 3, and turned into 'said clearance-groove 4 under said lock-shoulder 5, and which springlever is engageable with a seat formedon said clevis-yoke, substantially as described.
3. The combination with a clevis-yoke 1, having bolt-seats in its prongs and having on one of its prongs, adjacent toitsbolt-seat, a notch 3, segmental clearance-groove 4 and IOC - lock-shoulder 5, the said prong of said yoke .With said lock-groove 7 substantially as dehaving a guard-lange 10 and camsurface 6 scribed. 1o formed With lock-grooves 7 of a look-bolt 2 Irl testimony whereof I affix my signature rovded With Mock-shoulder 11. andaspringin presence of two Witnesses.
5 ever 8, which lock-lug is insertible through EDWIN J. J. GREGEBSON.
said notch 3 and is adapted tobe turned into Witnesses: said groove 4 under said lock-shoulder 5, and P.f C. FINVOLD,
the free endfof Which lever 8 is engageable l KATIE E. FINVOLD.
