UNITED STATES PATENT OFFICE.
JOHN J. MULVANEY, JR, OF CINCINNATI, OHIO, ASSIGNOR OF ONE-HALF TO ANDRE\V P. DUMLER, OF SAME PLACE.
NUT-LOCK.
SPECIFICATION forming part of Letters Patent No. 375,711, dated December 27 1887. Application filed August 8, 1887. Serial No. 246,401. (No model.)
To 610% whom it may concern:
Be it known that I, JOHN J. l\IULVANEY,Jr., a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.
The object of my device is to provide a means by which a nut may be securely locked on a bolt, which nut, from various causes, is liable to become loosened.
My invention is for use, principally, in securing the joints of railroad-rails, where the continual travel and jar of the train is liable to loosen the nuts on the bolts which secure the fish-plates.
In the accompanying drawings, Figure l is a View in elevation of my device when applied to the joint of a railroad-rail, showing the four nuts locked in difierent positions. Fig. 2 is a cross section taken at the line 00 x of Fig. 1 and showing one form of tool for swaging the ends of the locking-plate. Fig. 3 is an edge view of my improved locking-plates, the. two nuts at the left hand being shown locked,
and the two at the right hand being unlocked.
\Vhen used to secure the meeting ends of railroad-rails, my device is preferably con structed and applied as shown in Fig. 1. The fish-plates A are first placed over the joint of the rails Bin the usual manner. In case four bolts are employed for one joint, I use two of my improved locking-plates O and 0. These two plates are constructed exactly alike, except that the plate 0 is longer than plate 0. These locking-plates are preferably constructed as shown, the ends of each plate being doubled under and the bolt passing through the doubled portion. After the locking-plates are secured by screwing the nuts on the bolts as tightly as desired, I employasuito ably-shaped tool, D, the point of which is preferably conical in shape. This tool is driven into the doubled end portions, E, of the locking-plate, thus swaging the metal up against the nut at whatever angle it may be placed and 5 securely looking it on the bolt.
Instead of using the tool G for swaging the metal up against the nut, the nut may be screwed down very tightly on the doubled portion, and thus will swage the doubled end portion without the aid of the tool.
My improved nut-lock is very effective and is cheap of manufacture. The ends of the locking-plate, being doubled and then swaged against the nut, increases the strength of the 5 5 lock twofold and renders the same doubly secure.
To remove the nut, the swaged portion is flattened with a hammer, the nut then being free to turn. The nut can also be turned by using a wrench. When desired, the pins D may be left in the double locking portion.
WVhat I claim as new and of my invention, and desire to secure by Letters Patent, is-
In a nut-lock, the combination of the loclcing-plate 0, having the doubled swaged ends E, bolts G, passing through said doubled portions, and nuts H, substantially as and for the purposes specified.
