PETER K. EBERSOLE, OF CONOY TOWNSHIP, PENNSYLVANIA, ASSIGNOR ()F ONE-HALF TO ISAAC WV. HOFFMAN, OF ELIZABETHTOWN, PENNSYL- VANIA.

NUT-LOCK.

.-.PECIFICATION forming part of Letters Patent No. 716,395, dated December 23, 1902.

Application filed July 23, 1902. Serial No. 116,619. (No model.)

T0 at whont it may concern:

Be it known that 1, PETER K. EBERSOLE, a citizen of the United States, and a resident of Gonoy township, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in NutLocks, of which the following is a specification.

This invention relates to improvements in that class of devices designed to prevent the voluntary loosening of nuts on bolts, applying more particularly to the locking of nuts on the bolts securing the parts of a railwaytrack; and the object of this invention is to secure bolt-nuts by a lock held in place by a yielding device that wili hold it in an operative position and at the same time permit it to be readily removed.

The invention consists in the construction and combination of the various parts, as hereinafter fully described and then pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation showing a nut-lock embodying my invention applied to the rails of a track; Fig. 2, a top plan view of the same, the head of the rails being shown cut away; Fig. 3, a top perspective view of the joint between the rails and of an end of the nut-lock; Fig. 4, a transverse section on broken line 4 4 of Fig. 3; Fig. 5, a perspective view of thelocking-plate, and Fig. 6 a perspective view of a key for detaching the clamp-plate. Fig. 7 is a perspective view of a section of a modified form of the clamp-plate.

Similar numerals indicate like parts throughout the several views.

Referring to the details of the drawings, 1 indicates the rails; 2, the fish-plate; 3, the bolts, and a the nuts. These nuts 4 when screwed home are secured in place by a locking-plate 5. Locking-plate 5 bears against the fish-plate and has therein recesses or notches 6, adapted to take around and prevent the turning of the nuts on the bolts On each end of locking-plate 5 is an outwardly-extending lip 7, through which is a perforation 8, wherethrough passes the stem 9 of a hook 10. On the inner end of each stem 9 is a coiled 5o spring 11, having the inner end 12 engaging a hole in the inner end of said stem and the outer end engaging the inside face of lip 7. Hook 10 has thereon a shoulder 13, that bears against the outer face of lip 7 and limit-s the action of spring 11. From lip 7 hook 10 curves inward, then parallel with the rail, as shown at 14, and finally'embraces the shoulder formed by the end of the fish-plate, as seen at 15.

In Fig. 7 is shown a modified form of the locking -plate, wherein openings 16 are out through the body thereof.

In operation the hook at one end of the locking-plate is engaged with the end of the fish-plate. The locking-plate is then pulled against the tension of the spring on the stem of that hook until the openings in said locking-plate engage the nuts 4, when the hook at the other end of the locking-plate is engaged with the corresponding end of the fish-plate. To detach the locking-plate, the key or lever 17 (illustrated in Fig. 6) is inserted in the space at one end of said locking-plate, formed by the inward curve of hook 10, as shown in Fig. 3.

I do not confine myself to the details of construction herein shown and described, as it is obvious that many alterations may be made in the same without departing from the principle and scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a nut-lock, the combination, with a bolt, of a shoulder in fixed relation to the bolt, a locking-plate, engaging a nut on the bolt, a hook engaging the shoulder, a stem on the hook and extending over the lockingplate, and a resilient connection between the locking-plate and said stem, for the purpose specified.

2. In a nut-lock, the combination, with a bolt, of a shoulder in fixed relation to the bolt, a locking-plate engaging a nut on the bolt, a lip on the locking-plate, a hook engaging the shoulder, a stem on the hook and passing loosely through an opening in said lip, and a spring connected with the stem and bearing against the lip, for the purpose specified.

3. In a nut-lock, the combination, with a plurality of bolts, of shoulders on opposite sides of said bolts and in fixed relation thereto, a locking-plate engaging the nuts on the bolts, lips on the ends of the locking-plate, hooks engaging the shoulders and having stems passing loosely through the lips of the locking-plate, and springs on said stems and adapted to exert inward tension on the hooks, for the purpose specified.

4. In a nut-lock, the combination, with a fish-plate, of a locking-plate 5 having openings therethrough adapted to take over a series of bolt-nuts, perforated lips 7 on the ends of the locking-plate, hooks 10 comprising PETER K. EBERSOLE.
