- IMPROVEMENT m NUT-LOCK.
Spcgifieation forming part of Letters Patent Nu. 106,668, dated August 23, 1870 nntodnted August 11, 1870.
I, DAVID CUMMING, Jr., of Brooklyn, in the used on railroads or other places subject to vibration, and is an improvement on an illvention for which Letters Patent of the United States No; 78,864 were issued tome June 16, l 868.
Description of {he Acconqmny-ing Drawing.
Figure 1 is a perspective View of a screw bolt embodying my invention. Fig. 2 is an end view of the same. Fig. 3 is a plan of the nut. Fig. 4 is a section of the nut parallel .with its axis. Fig. 5 is a longitudinal section through the center of the bolt.
General Description. A isthe bolt, in the threaded part of which I cut a key-seat, X, into which. I insert the key (1, of lead, copper, or other soft metal. B is the nut, on the outside face of which lniakc the indentations 1). 4
When the nut is screwed onto the-bolt, the thread of the nut cuts a corresponding thread on the soft-metal key, thereby preventing the key. from coming out.
. hen the nut is screwed up to its place, that part of the key over which the nut has passed is bent or riveted up against the outside face of the nut and driven into the indentations, thereby locking the nut on the bolt more eflectually than by using only my prcvious invention herein mentioned.
I claim as my invention The combination of the indentations with the soft-metal key 0', substantially as and for the purpose set forth.
