NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 355,372, dated January 4, 1887.

Application tiled May 4, 1886. Serial No. 201,113. (No model.)

- To all whom t may concern.:

Be it known that I, GOODWIN O. BisHor, a citizen of the United States, residing at Hannibal, in the county of Marion and State'of Missouri, have invented certain new and useful Improvementsin Arch-Spring Nut Locks and Clamps; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to arch spring nut locks and clamps; and it consists in the construction and arrangement of the parts, which will be more fully hereinafter described, and pointed out in the claim.

The object of my invention is to provide a spring nut-locking bar composed of a series of arches intersected by indentations which rest against the angle-bar, the arches forming base-rests for the nuts, said locking-bar entire being braced and held in position at its ends by suitable means on the angle-bar. I attain this object by the construction illustrated in the accompanying drawings, wherein like letters of'reference .indicate similaiparts in the several views, and in which- Figure l is a perspective view of portions of rails forming ajoint with the angle-bars in position and with my improved ar'clrspring nut-lock applied in connection therewith. Fig. 2 is a detail perspective view of my improved arch-spring nut lock and clamp. Fig. 3 is a transverse vertical section on the line :c a of Fig. l, and Figs. 4 and 5 are detail views in side elevation of modified forms of securing the ends of the locking-bar.

A indicates therails, B B the angle-bars, and C C the tiesA or sleepers.

Adjacent to one of the angle-bars B a springplate, D, is placed, which is formed with a series of arches, d, which have apertures d drilled or cut in their central portions, through which the bolts E E pass, the nutsE E being screwed home on said bolts on the outer face of the plate D, said plate forming a basewasher for the nuts at these points. A short curve or depression, d2, connects the long arches d, being arranged about midway between two of the boltsE E and restingagainst the angle-plate B. This short curve or depression d forms a base-rest for the ends of the arches d, which arches bear against the nuts E'at all times and prevent them from turning, and, consequently, loosening the joint of the rail.

As shown in Fig. 1, the ends cl3 ofthe springplate D are engaged by small studs d4, secured in the angle-plate B.

As shown in Fig. 4, the ends ofthe angle- 6o bar are struck up or formed with projections, against which the ends of the said arch-spring plate D rest and are secured. In Fig. 5 the ends of the plate D are shown as formed with flattened or chisel ends, which engage with recesses formed in the angle-bar at the points where the two ends of the plate engage withthe said anglebar. The plates may be sprung into engagement with these projections and recesses, and become thereby secured to the an- 7o gle-bar.

In applying my improved nut-lock in connection with a rail-joint the operation is as follows: The plate D is adjusted with relation to the end fastenings, the bolts E are passed through the angle-bar B and the rail, and through the apertures d in the plate D, and the nuts E screwed home on said plate. Single arches can be readily formed on the same principle ofthe continuous series, adapted to 8o be used in connection with single bolts. As many arches can be constructed as are necessary to suit the number of bolts by whichthe are to be engaged.

The spring-plate maybe made of varying thickness and width to suit the desired application. w

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

As an article of manufacture, an arch-spring nut-locking plate and clamp consisting of a series of long curved arches which form lbasewashers for the nuts, short curved base-rests between the arches, said long and short curves 9 5 being convexe-concave, respectively, throughout the whole length of the bar, and means for securing the ends of the plate, substantially as GOODWIN O. BISHOP...
