ALBERT BERRYHILL, OF PITTSBURG, PENNSYLVANIA.

d NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 252,719, dated January 2'4, 18 2.

Application filed September 13, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALBERT BERRYHILL,Of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Nut-Lock, of which the following is a specification.

The invention consists of two grooved blocks held in a longitudinal slot of a plate placed on the bolts and over a recessed plate, which in turn is placed against the fish-plate or against a plate resting against the fish-plate, which blocks are held against thenuts to prevent them from turning by a locking-wedge placed between them and into the recess of the recessed plate, parts of the slotted plate being bent outward to form an aperture to admit the lockingwedge.

Reference is to be had to the accompanying drawings, forming part of this specification,in

which similar letters of reference indicate cor- V responding parts in all the figures.

Figure 1 is a plan view of a part of a rail is a longitudinal elevation of the slotted and apertured outside locking-plate. Fig. 4 is a longitudinal elevation of the recessed fillingplate. Fig. 5 is a longitudinal elevation of the first filling-plate to be placed against the fishplate.

locking-wedge. Fig. 7 is a perspective view of -one of the locking-blocks.

The bolts A A are passed through the fishplates B B and through the web of a rail, (1, in the ordinary manner,'a-nd the heads A of the bolts are driven up firmly against the fishplate B. A metal strip or plate, D, provided at the ends with apertures'E E, of such size as to admit the threaded ends of thebolts A, and separated a distance equal to the distance the bolts A are separated, is placed against the-fishplate B, the threaded ends of the bolts A passing through the apertures E. A metal plate, F, providedwith two apertures, G, of the same size as the apertures E of the plate D, and separated a like distance, is then placed against the plate D, the threaded ends of the bolt A passing through the apertures G. The plate F is provided with a large rectangular recess, H, in its upper edge.

A plate, J, is provided with two apertures,

Fig. 6 isa longitudinal elevation of the K K,of the same size and separated a like distance as the apertures E and G. A slot, L, extends from one aperture, K, to near the other, or the two apertures may be united by the slotL. Notches or cuts M extend upward and downward from the slot L into the plate J, at or near the middle of the slot, thus permitting the part N of the plate between the cuts M to be bent outward.

Blocks 0 are provided in the top and hotton with grooves P, of the same width as the thickness of the plate J, each groove forming two flanges .or ridges, Q Q, at the edges of these blocks 0, of which ridges the inner one, Q, must not be of greater thickness than the distance between the plates D and J-that is, the ridge orflange Q must not be thicker than the plate F. The block 0 is to be ofsuch size that it can be 3 passed into or, through the aperture K, connected with the slot L. A locking-wedge, B, consists of a-segmentally-bent wire having two upwardly projecting and converging arms, S S, and is of such size asto fill the space between the blocks 0. In place of the spring-wedge R, any other suitable fillingpiece may be inserted between the blocks 0.

The operation 'is as follows: The plates D and F having been placed on the bolts A, as previousl y mentioned,the blocks 0 are passed into the aperture K of the plate J, and are passed into the slots L, the ridges Q of the block being on the front side and the ridges Q on the rear of the plate J. The plate J is then placed against the plate F, the ends of the bolts A passing through the apertures K. Then the nuts T are screwedon thebolts A, and are turned down tightly. Then the blocks 0 are pushed to the ends of the plates J to rest against the nuts T. For the purpose of locking the blocks 0 in this position the part N between the notches M is bent outward and the locking-wedge R is inserted between the blocks 0, whereby these blocks will. be held in their position, resting against thcnuts T, and thus prevent the nuts from turning. After inserting the locking-wedge R the parts N 'are bent back again. If the nuts are to be loosened or removed, all that is necessary is to bend the parts N outward, remove the wedge R, and push the blocks 0 to the middle of the slot L.

Having thus fully described my invention, I

claim as new and desire to secure by Letters slotted plate J, the plate D, the blocks 0, and :0 Patent the wedge or filling piece R, substantially as 1. In a. nut-lock, the combniation, with the herein shown and described, and for the purholts A and nuts '1, 0f the recessed plate F, the pose set forth.
