NUT-LOCK.

I Specification of Letters Patent. Patented Feb, 22, 1921.

Applicationfiled April 17, 1918. Serial No. 229,194.

To all whom it may concern:

Be it known that I, JOHN J. BENTZ, a citizen of the United States, residin at Bronx, county of Bronx, and State of ew York, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.

This invention relates to means for securing nuts with relation to their bolts, so that the same may not become loosened.

The principal object of the invention is to provide means cooperative with the nuts and bolts, by which the nuts are prevented from movement when set in adjustment.

A further object is to provide a securing device the ends of'which are so formed as to engage respectively with the bolts and nuts, all of several parts being of simple construction and readily manufactured.

These and other like'objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a side'elevational view, partly in section showing a bolt and nut made in accordance with the invention.

Fig. 2 is a top plan view of the same.

In the drawing 10 indicates the shank or body of the bolt which on one end is provided with the customary head 11 while its opposite end 12 is screw-threaded as usual.

As shown, the screw-threaded portion 12 is provided with a longitudinally extending slot 16 passing transversely across the convolutions of the thread, the slot being adapted to contain the body of a key 17 The slot 16 has formed with it a plurality of lateral, inwardly extendingrecesses 22 receivable of the bent end 18 of the key 17 the upper end of which is formed intoan outwardly extending element 23, terminating in a downturned hooked portion 24, en gageable within any of a plurality of openings 25 formed in the top'of the nut 26, while a lug 28 extends outwardly and downwardly from the key 17 below the bent end 18. n

It will be clear that the lug 28 can be engaged by a bar or the like for springing the key sufiiciently out of the slot 16 to permit the bent end 18 to clear or to be retracted from any of the several recesses 22. The longitudlnal slot 16 is deep enough to accommodate the key 17 entirely, and a groove 21 in the nut 26 allows a certain play of the key 17 when the bent end 18 of the same is sprung out of the recesses 22.

In operat on, the key 17 is placed into the slot 16 with its bent end 18 engaging any of the recesses 22, then the nut is screwed home and the upper end of the key is then bent by a suitable tool to engage any of the openlugs 25. When it is desired to release the nut, the upper bent end of the key is and a plurality of inwardly extending recesses, a nut threaded on the shank, and haying a groove in its body, and a'plurality of openings formed in its top, and a ke adapted to be received in the longitudina slot of said shank, outwardly extending element at the uppei end of said key, terminating in a downturned hooked portion adapted to engage in any of said plurality of'openings in said nut, a bent end at the lower end of said key, adapted to engage in any of said inwardly extending recesses, said hooked portion allowing a springing of the key sufficiently to permit a retraction of said hooked portion from the opening in said nut by a tool, a lug extending outwardly and V downwardly from the lower bent end of said key, adapted to be engaged by a tool for springing said bent end of the key out of one of the recesses in said shank, the groove in said nut permlttlng the key to be sprung out of said recesses when the nut is on the shank.

In testimony whereof I have afiixed my signature.
