Oct. 14, 1930. v P. H. D. WALKER I I I 911% CLAMPING ELEMENT FOR VIBES ANDSIMILAR ARTICLES Filed Dec. l3, 1929 Patented Get. 14, 1930 PERCY H. D. WALKER,


This invention relates to improvement in clamping devices for various purposes where nuts and bolts are used, with particular reference to providing clamping elements which are to be operated by wrenches and which are particularly designed for use in connection with rotatable Vises. In some cases, and as in vises, it is desirable that the wrench shall always be in position for operation, and means should be provided to prevent its entire removal from the element with which it is used. Various devices have been made for this purpose and the object of this invention is to provide a clamping element, simple in construction and from which a wrench may be removed, if desired, although not likely to be accidentally removed, and the invention consists in the construction as hereinafter clescribcd and particularly recited in the claim.

In the accompanying drawings Fig. 1 is a side view of a vise showing one of my improved clamping elements in connect-ion therewith;

Fig. 2 is a side View of a clamping element of bolt form;

Fig. 3 is a top view of the same;

Fig. 4 is a side view of the element with a wrench attached;

Fig. 5 is a side view of the element with its a ming-ring removed;

Fig. 6 is a perspective View of the ring detached;

F ig. 7 is a side View of a clamping element of nut form; and

Fig. 8 is a plan view of the same.

In carrying out one form of my invention, I employ a bolt having a threaded shank 10 and a polygonal head 11, above which rises a round neck 12 and near the outer and of the neck is an annular groove 13 to receive spring-ring 14 providing an annular flange slightly greater in diameter than the diameter of the polygonal head, and the length of the neck between the angular portion and the ring is somewhat greater than the thickness of the head 15 of a wrench 16 which is placed onto the element before it is in its clamping position. 7

It is obvious, as shown in Figs. 7 and 8 of the drawings, that the invention may be Serial No. 413,744.

applied to clamping elements of nut type, the nut being threaded and having a. polygonal wrench-receiving portion 17 and a neck 18 formed w th an annular groove to receive a clamping g 19 which operates in the same way as the clamping device of the bolt type first described.

In. either case, an annular flange is pro vided at the upper end of the round neck, eX- tending beyond the angular portion of the nent, so that a wrench is always in posin to turn the element, but can be readily ed above the polygonal part and turned reparatory to taking anew grip without anger of its slipping off from the element, with the further advantage that if necessary or desirable, the spring-ring may be removed from the neck so that the wrench may be applied or removed from the clamping element without entirely detaching the clamping element from its complementary part.

I claim:

A clamping element comprising a threaded part, a polygonal or faceted wrench-engaging portion, a neck made integral with, extent ing beyond, and smaller in diameter than the same to permit the wrench to turn freely upon it, and formed close to its outer end with an annular groove; and an open ring formed of hard spring wire located in the said groove than which it is normally smaller in internal diameter, and projecting out of the said groove to form a substantially-continuous, overhanging, annular guard larger in external diameter than the diameter of the said polygonal wrench-engaging portion.

In testimony whereof. I have signed this specification.
