LOCK-PIN..
Specification of Letters Patent.
Patented Oct. 20, 1908.
Application filed. November 20, 1907. Serial No. 403,071.
To all whom it may concern:
Be it known that I, VINCENT V. PITTMAN, a citizen of the United States, residing at Santa Cruz, in the county of Santa Cruz and State of California, have invented new and useful Improvements in Lock-Pins, of which the following is a specification.
This invention relates to lock pins, the obj ect of the invention being to provide a lock pin embodying two pivotally connected curved members one of which is pointed and the other recessed to receive the end of the pointed member, in connection with a clamping device for securely clamping the pointed end of the pin to the recessed end of the other member thereof.
With the above general object in view, the invention consists in the novel construction, combination and arrangement hereinafter fully described, illustrated and claimed.
In the accompanying drawings :Figure 1 is a sectional elevation of the pin embodying the present invention, shown closed. Fig. 2 is a similar view of the pin, shown open. Fig. 3 is a detail cross section through the pin as shown in Fig. 1, taken in about line with the pivot of the clamping cam. Fig. 4: 1s a cross section through the pin, showing the manner of forming the clamping jaws. Fig. 5 is a longitudinal section of the clamping aws.
The lock pin contemplated in this invention comprises essentially two members, one of which may be termed the pin member 1 and the other the socket member 2. The socket member 2 comprises an outer tubular casing or sleeve 3 within which the clamping jaws 4: and 5 are housed.
The clamping jaws may be formed of a. single piece of spring metal and recurved or folded upon itself as indicated in Figs. 1, 2 and 5, the same being preferably formed of half round material as shown in Fig. 4 with the flat sides brought together.
The two clamping jaws formed in the manner above described are bent into substantially semi-circular form and inserted or held tightly in the casing or sleeve 3 with the extremities of the jaws reaching to the corresponding extremity of the casing 3. In order to provide for the insertion of the pointed extremities of the pin 1 between the jaws, one or both of the jaws may be decreased in thickness as shown in Fig. 3so as to admit the pin between the jaws and also allow for the necessary play of one of the jaws to release the pin when thej aw itself is released, the tendency of the jaw being to spring away from the pin so as to readily release it.
The tubular casing or sleeve 3 is provided near the pin point receiving end with oppositely located pivot lugs 6 between which is mounted a cam 7 having a handle 8 the cam being pivotally connected with the lug 6 by means of a pin 9 or its equivalent.
The disposition of the cam relatively to its operating handle is such that when the handle 8 is thrown towards the adjacent end of the casing or sleeve 3, the jaws will separate to release the pin point and when said handle is swung in the reverse direction to the position shown in Fig. 1, the head of the cam will press the adjacent jaw against the side of the pin point and clamp the pin securely between the two jaws, thus making a perfectly safe lock for the pin when closed.
10 designates a slot in one end of the casing which permits the pin member 1 to swing outward to the position shown in Fig. 2. Both members of the pin are substantially semicircular and arranged so that when closed they will form a ring as shown in Fig. 1.
I claim 1. A look pin comprising two pivotally connected semi-circular members, opposing jaws 011 one member between which the point of the other member is received, and a cam operating in conjunction with the jaws to clamp the pin point.
2. A look pin comprising two pivotally connected semi circular members one of which is pointed, a movable jaw on the other member, and a clamp to force said jaw against the pointed member to lock the free ends of the two members together.
In testimony whereof I afiix my signature in presence of two witnesses.
VINCENT V. PITTMAN.
