NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. esasoz, dated January 5,1886.

Application filed October Q7, i885.

To all whom it may concer-12,:

Beit known that I, JOHN P. CHAMPION, a citizen of the United States,residing at Gainesville, in the county of Hall and State of Geor- 5 gia, have invented anew and useful Improvement in NutLocks, of which the following is a specication, reference being had to the accompanying drawings.

Myinvention has relation to improvements 1o in nut-locks; and it consists of the peculiar construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and speciiically pointed out in the claims.

Myinvention has for its object to provide a nut-lock which shall obviate the objection of the bolt working loose and rattling in the sockets in the lish-plates and rails, caused by the jar and strain upon the rails when a train passes over the same; to prevent the securingnuts from working loose or turning and becoming detached from the bolts; and to combine simplicity, strength, and durability of construction with thorough effectiveness of operation and ease ot' application to and re moval from the nuts and bolts.

In the accompanying drawings, Figure l is a side elevation of an ordinary rail having my improved nut-locking device applied thereto. Fig. 2 is a transverse vertical sectional view on the line xx of Fig.l. Fig. 3 is a detail perspective view of the spring securing-plate. Fig. 4t is a like view of the nut-locking plate, and Fig. 5 is a detail view of a spring fastening-key.

Referring to the drawings, in which like letters of reference indicate corresponding parts in all the figures, A A designate the sections of the rails, of ordinary construction; B, the ish-plate thereof; C C, the through-bolts passing through the iish-plates and rails,'and having a head, c, bearing on one ofthe fish-plates, and a threaded Iend which projects beyond the opposite fish-plate; and D, the securing-nuts.

Two bolts, C, are arranged on each side of the line where the rails A A meet or abut together; and I will only describe the means for securing two ot' such bolts in position, it being understood that each pair of bolts are provided 5oA with the locking devices.

Serial N0.'181,090. (No model.)

E designates a spring-plate, which when it is detached from the bolts assumes the curved shape shown more clearly in Fig. 3, said plate being spaced aparta distance equal to the d istance between the bolts. This spring-plate is l provided at one end with a turnedup lip or flange, f, having an aperture, f', at or near its middle, and at its opposite end it has an eye, f2, for a purpose presently described. The nut-securing plateA has squared aperturesrg at or near its middle, which ts over the nuts I),aprojecting nib,7t,at one end which tits in the aperture JN, and an eye, h', at its opposite end, which,when the securing-plate to which it is attachedis secured to the nuts,registers with the eye f 2 of the spring-plate E, and these eyes receive a key, I, (shown in detail in Fig. 5,) which serves to secure one end ofthe platesE G together, while the opposite ends thereof v are secured or held in position together by the tongue h, fitting' in the aperture f ot' the spring-plate.

In applying my improved nut-locking device to the rails the spring-plate E is first iitted over the shanks of the bolts, so as to leave the lip f and socket f2 projecting forwardly thereof. The nuts `D are then fitted on the bolts and screwed home, so as to force the spring-plate close against the fish-plate. The lip h ofthe plate G is tted in the socketf of the spring-plate, and the end of said plate G to which the tongue is attached itting beneath the lipf of said spring-plate, the apertures g fitted over the nuts D, and the eye h registering with the eye f2, and the springkey I passed through said eyes or sockets f2 h. By means ot' the spring-plate E bearing against-the nuts of the bolts the heads of said bolts are drawn firmly against the fish-plate; and the shanks thereof prevented from working loose or turning in theirsocket in the webs of the rails and fish-plates, longitudinal strain being exerted on the bolts, which serves to keep the shanks from turning, and by reason of the plate G Iitting over and engaging the nuts on the bolts said nuts are prevented from turning and becoming detached.

IOO

My improved nut-lockis simple, strong, and durable in construction, thoroughly effective for the purposes designed, can be easily and quickly applied to and removed from the securing-bolts, prevents the bolts from working loose in the sockets and wearing them elliptically shaped, and can be manufactured cheaply.

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

1. The combination of the rails, the shplates, the through-bolts having nuts, an elastic pressure-plate interposed between the nuts and the fish-plates, and a nut-securing plate detachably connected to the elastic pressureplate, substantially as described.

2. The combination of the rails, the fishplates, bolts having nuts, a spring pressure plate fitted over the bolts and interposed between the nuts and fish-plate, and a rigid se- .-f-;curingplate detachably secured to the spring pressure-plate, and having sockets g to enplate, the through-bolts having nuts, a spring pressure-plate interposed between the nuts and fish-plates, and having a socket at one end and an eye at its opposite end, a nut-securing plate having a tongue to engage the socket of the spring pressure-plate. and an eye that registers with the eye of said pressurea spring` fastening-key, I, substantially as de` scribed.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
