CHARLES A. SMYTH, OF HOOPESTON, ILLINOIS, ASSIGNOR OF A PART OF HIS RIGHT TO DAVID BEDELL, OF SAME PLACE.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 235,583, dated December 14, 1880.

Application filed December 23, 1879.

To all whom it may concern Be it known that I, CHARLES A. SMYTH, of Hoopeston, in the county of Vermillion and State of Illinois, have invented a new and Improved Nut-Lock, of which the following is a specification.

My invention relates to a nut-lock especially adapted for service upon railroadrails at the joints thereof; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claim.

The object of my invention is not only to simplify the construction of nut-locks, but also to increase the efficiency of the same.

In carrying out my invention I employ the ordinary fish-plate adapted to serve at the joints of railroadrails, being bolted thereto and secured by nuts. The nuts are to be kept in fixed positions and prevented from turnin g.

. To this end I employ a plate-washer perforated to receive the bolts and cut away at one end to form a lip, and at the other end cut to form a locking lip, perforated as shown. This Washer-plate passes over and embraces the bolts, which are threaded and adapted to receive the securing-nuts. I also provide a lockplate having a recess upon one end, which receives the lip hereinbefore mentioned, and at the other end a slot, which receives the lock' ing-link. This plate is formed of one piece of metal, and is cut and struck up in such a manner that the material is bent at a right angle with the plane of the blank to form side rests, which bear against nuts.

The device employed by me, and which embodies my invention, is fully illustrated in the accompanying drawings, in which- Figure l is a side elevation of a railroadrail, showing my invention with the nut-lock in a locked position. Fig. 2 is a central longitudinal section through the line w m, Fig. 1. Fig. 3 isa vertical section; and Fig 4, a similar section, showing the locking-link in position.

Referring to the drawings, A represents the rail; B, the fish-plate; O G, the bolts, and l) l) the nuts. These are of ordinary construction, and comprise no part of this invention. E-represents the washenplate, perforated at distances to correspond with the bolts, and

cut at a point near one end to form a lip, a. This lip a is inclined as shown. Near the other extremity is a trifaced out, which forms a flange, b, perforated at h and bent at right angles to the plane of the washer-plate E. The washer-plate E is passed over the threaded ends of the bolts and the nuts applied and secured in corresponding positions.

F represents the lock-plate, of one piece of sheet metal, and itis provided at one end with a recess which embraces the inclined lip a, and at the other end with a slot, g, which re ceives the perforated locking-lip b. This plate F is struck up and cut in such a manner as to form apertures cc to receive the nuts D and to form lugs d d, which embrace said nuts when the plate is in position. The fish-plate having been put in position and the headed bolts 0 having been passed through both rail and fish-plate, the plate E is attached and secured by means of the nuts I). To prevent these nuts from turning, plate F is first engaged with the lip a, and then, being placed over the nuts, is locked in such position by the open link G, which operates in the perforation It of the locking-lip b.

It will be observed that both the washerplate and the lockin g-plate are formed each of onepiece of sheet metal, and,further, that their formation may be due to one stroke of proper dies.

It will also be observed that the plate E so formed furnishes the male locking devices for the female or lock plate F.

It will also be observed that the lugs d serve materially to strengthen the lock and efficiently assist in carrying out the invention.

What I claim as new is The lock-plate F,.having slot g, rectangular apertures so cut as to form holding-lips d d to bear against the nuts, formed of one piece ot metal, and recessed as shown, combined with the washer-plate E, cut away so as to form inclined lip a and locking-lip b, perforated at h, also formed of one piece of metal, the fishplate B, rails A, bolt 0, nut D,and opeu locking-link G, as and for the purp ses-set'firtl CHARLES ALBERT SMYTH.
