NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 485,120, dated October 25, 1892.

Application led .Tune 25, 1892.

To all whom it' may concern.-

Be it known that I, ISRAEL WOLFE, acitizen of the United States, and a resident of Goshen, in the county of Elkhart and State of Indiana, have invented certain new and useful Im provernents in Nut-Locks; andI do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, andin which- Figure lis a perspective View of my improved nut-lock complete as applied to a railjoint. Fig. 2 is a similar view of the joint and washer-plate, but with the locking-plate proper removed. Fig. 3 is a perspective detail view of the washer-plate. Fig. 4 is a similar view of the locking-plate from the side facing the washer-plate. Fig. 5 is a transverse sectional view through the rail-joint and lock on line x in Fig. l, and Fig. 6 is a similar View on the parallel transverse plane indicated by the broken line marked y y.

Like letters of reference denote corresponding parts in all the gures.

This invention relates to devices for locking the nuts on the bolts used in connecting the ends of railway-1'ails in rail-joints; and it consists in the combination,with the bolts and nuts of the joint, of a removable locking device of novel construction, as will be hereinafter more fully described and claimed.

Referring to the drawings, the letters A A designate the meeting ends of two railwayrails of a rail-joint, B B the bolts, and C C their nuts. The fish-plates or angle-plates D D are of the usual construction and are placed one on each side of the joint. After the bolts have been properly inserted a Washer-plate E is placed upon their proj ect-ing ends, said plate E having apertures for the insertion of that end of the bolts whichis to receive the nuts. This Washer-plate is of the configuration shown more clearly in Fig. wthat is to say, it consists of a rectangular plate, of iron or other suitable metal, the middle part e of which is raised by bending it at both ends, so as to form transverse shoulders or oisets c c, forming, when this washer-plate is placed in posi- Serial No. 438,023. (No model.)

slot or space e between the raised part e and the adjacent fish-plate D. The shoulders c c are set back a sufficient distance from both ends to clear the nuts C and admit of their being screwed up upon or removed from the bolts.

The nut-locking device proper consists ot' a plate F, the upper part of which, of a somewhat reduced length and width, is bent or doubled upon itselt', as shown at G, so as to form a hook-shaped clamp adapted to be hooked upon and overlap the middle part or offset e' of the washer-plate. When the locking-plate F is in this position, it is prevented from slipping off of the washer-plate by lugs or catches ff upon the lower and inner side of plate F, which may be formed conveniently by bending oisets on the lower end of the plate inwardly, so that they will by the spring of thelockingplate when the same is placed in position slip in under the lower edge of the offset e on the washer-plate, as illustrated more clearly in Fig. 6, and thereby hold plate F in position. When the locking-plate is in this applied and operative position, its ends will rnpinge upon the sides of the squarelyturned nuts C, so as to eiectually prevent them from turning on their bolts B and working loose or jarring oft.

In order to easily manipulate the lockingplate, its lower middle part is bent outwardly at right angles, so as to form a projecting tinger-piece H, by taking hold of which the plate may readily be placed in position or removed, as the case may be. To remove the device, the lower end of plate F is by its nger-piece I-I pulled out from the offset c on the washerplate enough to release its catches ff, when it can be easily slipped ott said plate.

It will be observed that this device is exceedingly simple and inexpensive in construction, that it can be easily applied and as easily removed when desired,`aud that it forms an absolute lock for the nuts on both sides of the rail-joint.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. The combination, with the washer-plate E, having oi'set e', of the locking-plate F, having the overlapping part G and provided with IOO the outwardly-projecting finger-piece H, and inwardly-projectinglugs or catches ff, adapted to engage under the loWer edge of the Washer-plate, substantially as and for the purpose shown and set forth.

2. The combination,with the rails of a rail- Way-rail joint, of the bolts, nuts, Washer-plate E, having offset e', forming side shoulder c c, and the removable locking-plate F, made of spring metal, having the overlapping bent part G and provided with the finger-piece H,

and inwardly-projecting catches ff, adapted to engage with the under side of the offset on the washer-plate, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto aixed my signature in presence of two witnesses.

ISRAEL WOLFE.
