NUT-LOCK- Specification of Letters Patent.

Patented April 23, 1907.

Application filed September 27, 1906. Serial No. 336,436.

To a wlton't it may concern.-

Be it known that I, WILLIAM T. SoLoMoN, of Pittsburg, in the county of Allegheny, State of Pennsylvania, have invented a certain new and useful Nut-Lock, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of a section of a railroad-rail and fish-bars, illustrating my invention. Fig. 2 is a horizontal longitudinal sectional view of the fish-plate and showing the nut-lock staple ready to be inserted in the apertures of the fish-plate. Fig. 3 is a like view showing the nut-lock staple inserted in the apertures in the fishplate, and Fig. 4 is a perspective view of the nut-lock staple.

Like symbols of reference indicate like parts wherever they occur.

In the drawings, 2 represents the railroadrail.

3 represents the fish-plate. it represents the nut, and 5 represents the b0 t.

Above or at one side of the nut 4 in the fish-plate 3 are two apertures 6, which pass through the fish-bar and are enlarged or reamed out, as at 7, on the inner face of the fishplate. This a erture 6 is adapted to receive the nut-lock staple 8, which may be formed of spring-wire and provided with the lugs or humps 9, which engage with the fishplate in the enlargement 7.

The operation is as follows: The nut 4 having been screwed on the bolt 5, the staple 8 is inserted in the apertures 6 and driven through the fish-plate until the humps or 40 bends 9 engage with the inner face of the fish-plate at the enlargement 7, thus preventnut-lock.

ing the staple from jarring out. The staple 8 when thus inserted lies in the path of the rotation of the nut 4 and serves as a perfect When it is desired to remove the nut 4 from the bolt 5, the staple 8 may be pried out of the aperture 6 by any suitable instrument, thus leaving the nut free to turn on the bolt 5.

My nut-lockis cheaply made, easily applied by unskilled labor, and is most durable and effective.

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

1. A nut-lock staple having substantially parallel spring-arms, each arm being provided with a bend or hump at or adjacent to its end.

2. In a nut-lock, the combination of a fishplate having apertures located in the path of rotation of the nut, in combination with a nut-lock staple having substantially parallel spring-arms provided with bends or humps adapted to be held in engagement with the fish-plate at the inner ends of the apertures.

3. In a nutlock, the combination of a fishplate having apertures, said apertures being enlarged or reamed out at the inner end where they emerge through the fish-plate and located in the path of rotation of the nut, in combination with a nut-lock staple having substantially parallel spring-arms provided with bends 0r humps adapted to engage with the walls of said enlarged ends of the apertures.

In testimony whereof I have hereunto set my hand.
