SPECIFICATION forming part of Letters Patent 31950331348, dated December 8, 1885,

' Application filed March 12, 1885. Serial No. 158,560.

To all whom it may concern:

Be it known that I, JOHN Tenor, a resi-v dent of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Nut- Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in nut-locks, and is fully described and explained in the following specification and shown in the accompanying drawings, in which- Figure 1 is a cross-section of a railroad-rail provided with the usual angle-plates and with my nut-locking device, the nut-lock being seen partly in side elevation and partly in section, the plane of section of the rail and angle-plates being through the line a; 3 Fig. 2, and the View being in the direction indicated by the arrow a, Fig. 2. Fig. 2 is a side elevation of the rail, angle'plate, and nut locks. Fig. 3 is a similar view of thewasher forming part of the nut-lock. Fig. 4 is a front elevation of the washer and the locking-plate attached thereto, the hinge-joint which connects the two parts being shown in section in order to illustrate the spring S.

In these views, A is an ordinary railroadrail. B B are angle-plates lying on opposite sides of the rail and in contact therewith, and G is a common bolt passing through the rail and anglcplatcs, and having on one end a head, 0, the opposite end, I, being screwthreaded. The bolt.- is provided with a nut, H, which engages the screw-threaded portion I, and between the nut and the vertical flange of the angle-plate B is a washer, J, having a central bolt-opening, and provided at one of its sides with an integrally-termed cylindrical barrel, F, adapted to receive the rod or pintle of a locking device, and thus form a hingejoint between the two parts.

G is a lockingplate provided with an integrally formed rod or pintle, L, which is journaled in the barrel F, and provided, also, with a central recess of such form and size that the nut H cannot turn when seated therein. The barrel F is of such diameter as to admit a spring, S, coiled about the rod or pintle L, and having one of its ends, S, resting on the is out of the way of the nutl (No model.)

plate G, and the other end, S, resting on the washer J, the force of the spring being exerted to hold the plate and washer in close contact.

The application and operation of this device are evident. The edge of the washer J rests on the horizontal flange of the angle-plate B, and is. thus prevented from turning, and the plate G is prevented by its connection with the washer from turning in a plane parallel to the plane of the washer. When the not is to be put on or taken off, the plate G is retated about the hinge-joint F L, in the direction indicated by the arrow in Fig. 1, until it The nut is then screwed on or off, and the plate is released and springs back into contact with the washer.

I am aware that a gravityactuated lockingplate has been hinged to asupportingwasher in a device of the same class to which my in vention belongs, and I do not therefore claim, broadly, the combination of such a washer and locking-plate. The use of the spring in the hinge-joint which connects the washer and plate is a material advantage, in that it perinits the placing of the washer J in such a positionthat any one of its three plain sides is in contact with the horizontal flange of the angle-plate, whereas without the spring the washer can only be placed in the position shown in the drawings, in which the hinge-joint is at the top. Even when the spring is used, the washer and plate will ordinarily be placed in the position shown in the drawingsi. 6., with the hingejoint at the top-and I have shown the plate provided with feet or projections K K, giving it greater breadth of base. This is, however, not essential, and may be dispensed with, the sides of the plate G being made straight, as indicated by dotted lines in Fig. i, in which casethe entire nut-lock may be so placed that the hinge-joint F L is vertical, instead of horizontal.

Having now described and explained my secure by Letters Patent, is

1. In a nut-lock, the combination, with a bolt and nut, of a washer encircling the bolt in contact with the inner face of the nut, and not susceptible of rotation when in operative position, a locking-plate hinged to the washer, and adapted,when lying against the washer, to prevent rotation of the nut with reference to invention, what I claim as new, and desire to the washer, and aspring connecting the washer and locking-plate, and tending torotate the plate aboutits hinge-joint and to hold it against the washer.

2. In a nut-lock, the combination, with a bolt and nut, of a washer encircling the bolt in contact with the inner face of the nut, and not susceptible of rotation when in operative position, a locl ing-plate connected with said washer by a hinge-joint, and formed with a recess adapted to receive the nut and prevent the rotation thereof with reference to the washer, and a spring connecting the washer and lockingplate, and tending to rotate the plateabout said hinge-joint and to hold it in contact with the face of the washer and in position to lock the nut.
