lNVENTO/ B) t g g A TTOHNEYS I SAMUEL M. CHURCHILL,
PATENT Enron.
OF LAW'TEY, FLORIDA.
NUT-LOCK.
SPECIFICATION forming part of Letters Patent N 0. 452,662, dated May 19, 1891.
Application filed May 29, 1890.
To all whom it may concern:
Be it known that I, SAMUEL M. CHURCHILL, of Lawtey, in the county of Bradford and State of Florida, have invented a new and useful Improvement in Nut-Locks, of which the following is a full, clear, and exact description.
This invention relates to nut-locks for railroad-joints and other purposes, including both wood and metal structures, in which thelock is established by means of a washer applied to the nut of the bolt to be secured, and provided laterally or transversely of its face with a spring-tongue by which the lock is formed.
The invention is embodied in the construction of the body of the washer and the tongue forming an integral part of it, as hereinafter described.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 represents a view in perspective of my improved nut-locking Washer applied to a bolt and nut used to secure a railroadbar and fish-plates together; Fig. 2, an inner face view of the nut-locking washer. Fig. 3 is an edge view of the same, and Fig. 4 is a vertical section of the railroad-bar and fishplates in part and of the locking-washer applied to a nut and bolt securing the same. Fig. 5 isaview in perspective of the nut-locking washer applied to a bolt and nut used to secure two pieces of wood together.
A in Figs. 1 and 2 indicates arailroad bar or rail in part, with fish-plates B Bin part applied thereto. 0 is abolt securingthe same, and D its nut.
E is a nut-locking washer applied to the inner face of the nut. The washer E is of a dbuble thickness, being formed of two metal plates 1; 0, either riveted together on one side, as shown at (Z, or when the washer is applied to a wood surface secured by a screw 0, arranged to enter the wood, as shown in Fig. 5. It will only be necessary to speak of the two plate-sh c as being the one an outer and the other an inn er one, no matter how united or Serial No. 853,583. (No model.)
made to occupy their proper relation with v each other; but in each case they form a double washer. Said plates are preferably made of spring-steel and the outer plate 1) arranged to extend beyond the inner plate 0 on its one side, and so that the angles or corners of the nut D will, on turning the nut, sweep over such extended portion of the plate I), which extended portion is partly divided throughout its length by a slit 8 in the plate I), that makes of said extended portion a spring-tongue f. 1 The latter has a curved middle portion o, that projects above the face of the washer, but its free end is flush with (or below) said face. Hy thus constructing the spring tonguef and arranging it so that its main portion does not in its normal condition lie above or beyond the outer surface of the washer or face thereof, only its curved protruding portion 4; extending beyond the surface of said plate, there will be no necessity to hold the spring-tonguefdown when screwing on or taking off the nut D, and the projection v on said tongue will automatically act as a positive lock to the nut. Thus as the nut is screwed onto or off from the washer the angles or corners of the nut come against and ride over the curved projection o of the spring-tongue, forcing the latter down, and when the nut is screwed on or down after said corners or angles of the nut have passed 'in succession oversaid projectionr a fiat side of the nut comes in line with the split 3 in the plate 1), allowing the spring-tongue f to rise to its normal position and bringing the curved portion 1: up against the side of the nut to lock it; but, as before observed, the main portion of the spring-tongue does not project above the washer, so that there is no necessity to hold it down in putting the nut on or off to allow its corners to pass it, there is no danger of breaking said tongue, and the whole operation is simple and quick and the locking device automatic in its action.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The nut-locking washer E, composed of two plates or thicknesses b c,with the outer plate 1) extended to overlap the marginal side of (.1 and nut l), for operation together subthe inner plate 0 and slit at such extended stnntinlly as and for the purposes herein set 10 port-ion to form a spring-tongue f, arranged in forth.
its normal position to lie on a level with the V J i J 1. 5 outer plate, but provided intermediately of SAMUEI (JHURUIHI its length with a curved projection "U, which Vitnesses; projects above or beyond the outer surface CHARLES ll. CHURCHILL,
of the outer plate, in combination with bolt E. G. HILL.
