NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 313,149, dated March 3, 1885.

Application filed June 14, 1884.

To all whom, it may concern.-

Be it known that I, ARTHUR T. WVOODS, a citizen of the United States, residing at Champaign, in the county of Ghampaign and State of Illinois, have invented certain new and use ful 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 appertains to make and. use the same.

My invention relates to improvements in nut-locks used in connection with bolts and nuts which are applied for the retention of fish-plates on railway-rails.

The object of my invention is to provide a strong and durable and at the same time inexpensive device, which, when properly adjusted, will securely lock and hold the nut to which it is applied in position upon the bolt. It is of such form of construction as to be free from danger of breaking by sudden strains or severe shocks, and may be readily removed or readjusted without injury to its structure. The manner in which this object is attained is hereinafter fully described, reference being had to the accompanying drawings and letters of reference marked thereon, which constitute a part of this specification.

Similarletters refer to similar parts through out the several views.

In the accompanying drawings. Figure l is a section on linemx of Fig. 2. Fig. 2is aside view of washer and nut-lock as applied to joint of rail, with straight fish-plate and square ing shown as removed from the rail. Fig. 4 is a side view of the device, in which the locking-plate is shown as provided with a notch suitable for hexagonal nuts. Fig. 5 is a side view upon one'half the scale of Fig. 2, the locking-plate being turned upward, so as to clear the nut, this being its position when the nut is being adjusted.

Referring to the drawings, a represents a washer, made of iron or other suitable material, bent at a point intermediate of its ends, so as to form two right angles to the bent middle portion thereof, a hole being punched at a point near one of its ends to accommodate the bolt b, and the hole h provided for the re- Fig. 3 is a plan of Fig. 2, the parts be-- (No model.)

ception of the lockingplate c. The hole h may be either round, square, or of any other desired shape, depending upon the form of that portion of the locking-plate which is to pass through it. The rear end of thelockingplate 0 is bent at right angles to its forward end, forming the neck J, and is again bent at right angles to the neck, in a direction away from its forward end, so as to enable the bent portion to pass through the hole It in the wash er. The opposite end of the lockingplate is provided with a notch, l m, of such form as to be adapted to the shape of the nut used. The length of the locking-plate is such that when in the locking position shown in Fig. 2 the neck J will bear against the edge of the hole h which is farthest removed from the bolt 11, while its opposite end will be supported upon the nut by the lip in, the face Z being in contact with one of the edges of the nut, or nearly so, the nut being thus prevented from turning, while the corner k of the lockingplate bears against the fish-plate and prevents its removal without first slacking the nut,though, when desired, it may be turned in the hole h, so as to clear the nut and occupy the position shown in Fig. 5. \Vhen detached from the bolt, the locking-plate 0 and the washer a are entirely separate.

I do not wish to confine myself to any particular form of locking-plate, as it is evident that the notch in the same may be varied so as to conform to the style of nut used.

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

In a nut-lock, the combination of the lockingplate 0. having the neck J, and bent at right angles to the neck in a direction away from its forward end, with the washer a, bent as shown, and having a hole near one of its ends for the accommodation of the bolt 1), and the hole h, for the reception of the locking-plate, substantially as and for the purpose set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

ARTHUR T. \VOODS.
