UNITED STATES THOMAS E. Sl-IORTELL, OF PITTSBURG, PENNSYLVANIA.
l NUT-LOCK.
SPECIFICATION forming part of Letters Patent No. 677,603, dated July 2, 1901.
Application filed March 30, 1900. Serial No. 10,750. (No model.)
To all whom it may concern:
Be it known that I, THOMAS E. SHORTELL,
a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Nut-Locks, of which the following is a specification.
In the accompanying drawings, which make part of this specification, Figure I is a plan view of the nut-lock when locked. Fig. II is a like view, but showing the tool inserted to lift the end of the spring; Fig. III, a like view showing the position of the parts after the end of the spring has been released from its groove. Fig. IV isaside elevation. Fig. V is a detail of the spring.
The purpose of my invention, generally stated, is to devise a nut-lock which shall be uniform in its action, permanent in its structure, practically impossible to be unlocked by a jarring or other accident, and yet easy to lock and unlock when so desired.
In the accompanying drawings,which make part of this specification, I have illustrated the same as applied to a section of a rail with two fish-plates.
In the several views, 2 is a bolt having a head 3 and the usual nut 4.
5 is the rail-section.
6 and 7 are the fish-plates. One or both of the fish-plates are provided with shoulders a a in groove a to suit one end of a spring, as hereinafter described. If the nut-lock is always applied on the same side, only one of the fish-plates need be grooved.
8 is a stiff coil-spring interposed between the nut 4 and the fish-plate 6. One end of the spring is extended and bent at 8, so as to be on a shoulder a, adapted to lie in the groove a in the fish-plate 6. The other end of the spring 8 is bent upwardly, so as to look as a lock or a catch against any backward movement of the nut4 as said end abuts against one side of said nut.
9 is any suitable hand tool or pry fitted to be placed under the end 8 of the spring and lever the same from the. shoulder a. of the groove a, as hereinafter described.
The operation of the device is as follows: The bolt is thrust through the rail and fishplates. The spring 8 is slipped over the projectin g end of the bolt, with the end 5: lying flat in its seat a in the fish-plate 6. The nut 4 is then turned down until the spring is under strong compression, which effectually prevents the end 8 from lifting from the shoulder a of the groove a and at the same time increases the locking-surface of the end S against the side of the nut V 4. As the spring is stiff and strong in cross-section,the upturned spring of the end8 effectually pre' vents the return of the not 4 as long as the parts remain in their relative positions just described.
When it is desired to release thelocked nut, any suitable pry, such as shown at 9,is inserted under the end 8 and said end raised up on the edge of the groove. The nut can then be turned back, releasing the tension on the spring until the locking end S fails to strike against the side of the nut and hold the same from a reverse movement.
It will be observed that either of the shoulders a ct of the groove a acts asa seat to keep the spring from turning in either a forward or" backward movement. The shape and depth of this seat can obviously be greatly modified.
Having described my invention, I claim In a nut-lock, the combination of a bolt, a nut, a fish-plate and a locking-spring, one end of said spring seated horizontally on a shoulder projection in the groove of said fishplate and the other end of said spring being upturned to act as a dog against the return movement of the nut when the spring is compressed.
Signed at Pittsburg, Pennsylvania, this 24th day of March, 1900.
THOMAS E. SI-IOBTELL.
