NUT-LOCK.

Specification of Letters Patent.

Patented Mar. 16, 1915 Application filed February 9, 1914. Serial N 0. 817,597.

To all whom it may concern:

Be it known that we, J ERIMIAH U. LANIER and JAMES W. NEWsoM, citizens of the United States, residing at Newsom, in the county of Davidson, State of North Carolina, have invented certain new and useful Improvements in Nut-Locks; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in nut looks.

The object of the present invention resides in the provision of a device particularly adapted for locking the nuts on rail joints and which may be readily and quickly applied to the nuts after they have been applied and tightened.

It is further the object to provide such a nut lock which may be applied to any bolt and nut having adjacent thereto a flange or other projection against which a portion of the lock may abut.

A further object of the invention resides in the provision of such a nut lock which is efficient and durable in use at all times and which is of such simple structure that it may be manufactured at a comparatively low cost.

With these and other objects in view, the invention resides in the novel combination, formation and arrangement of parts to be more fully hereinafter described and illustrated in the accompanying drawings and particularly pointed out in the claims hereto appended.

Reference is had to the accompanying drawings and similar characters of reference designate corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of a rail joint, showing the improved nut lock associated therewith, Fig. 2 is a transverse sectional view through the rail joint on the line 22 of Fig. 1, Fig. 3 is a perspective view of the nut and Fig. 1 is a perspective view of the nut lock.

Referring now more particularly to the accompanying drawings, 5 designates the meeting ends of rail sections, and 6 the usual fish plates associated therewith. Bolts 7 are passed through the fish plates and rails and the nuts 8 are threaded on said bolts.

The nut lock which is associated with each bolt and nut comprises a single length i of resilient wire bent in substantially U- shaped form to embrace the inner portion of the nut and which has the free ends of its arms inwardly directed for the purpose of holding the lock on the nut. One arm of the U-shaped portion is provided with an extension 9 which is rearwardly directed to serve as a finger piece whereby the lock may be rotated and which may also serve as a stop, as hereinafter explained. The inner portion of the nut is preferably cut away at 10 at its inner portion to provide a circular surface to rotatably receive the lock.

The bight of the U-shaped portion is coiled at 11. This is an important feature, as in addition to lending resiliency to the U-shaped portion, the coils engage against the flange of the fish plate and form a stop to limit the rotation of the nut. In operation, the nuts are tightened on the bolts and the locks are then positioned about the cutaway portions of the nuts. Undesired rotation of the nuts will thus move the nuts until their coiled portions 11 engage the flange of the fish plate, whereupon the nuts will ongage said coiled portions and be held against undesired rotation. Should it be desirable under some conditions not to use the coils 11 as an abutment, the extension 9 may engage against the flange of the fish plate or other stop and the nut engage against the coils and be thus held.

It will be further noted that this lock can be used with a nut not having the cutaway portion 10. In this use the lock will embrace the bolt.

lVhat is claimed is:

1. In combination with a bolt and nut, a nut lock comprising a substantially U- shaped resilient member engaging the nut, a plurality of coils formed at the bight portion of said member and an extension formed at the free end of one of the arms of said member, said extension bearing against the surface against which the nut contacts.

2. A nut lock comprising the combination with a nut having its inner portion cut away to provide a circular surface, of a substantially U-shaped resilient member adapted to embrace said inner portion and a plurality of alined coils formed at the bight of said member.

3. A nut lock comprising the combination with a bolt and nut, of a substantially U- shaped resilient member engaging the inner face' of the nut and a plurality of coils gaging the surface against which the nut is 7 formed at the bight of said member and ento be screwed. v
