NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 266,476, dated October 24, 1882,

Application filed July 22, 1882. (No model.)

To all whom it may concern:

3e it known that I, ANDERSON D. HOLLAND, a citizen of the United States, resident at Newport, in the county otJackson and State of Arkansas, have invented a new and valuable Improvement in Nut-Locks; and I do hereby declare that the t'ollowingis at'ull,clear,and exact description of the construction and operation of the same, reference being bad to theannexed drawings, making apart of this specification, and to the letters and figures of reference marked thereon.

Figure l ofthe drawings is'a vertical cross sectional view. Fig. 2 is a side view. Fig. 3 is a horizontal section. Fig. 4 is a plan view, partly in section. Figs. 5 and 6 are detail views.

This invention hast-elation to nut-locks; and it consists in the novel construction and arrangement of parts, as will he hereinafter fully described, and particularly pointed out in the claims appended. I

In the accompanying drawings, the letter a designates the base bar or plate, which is cast in circular, square, or elongated form. For railroad use this plate is preferably oblong, and is provided with two or more perforations, b, for the passage of the coupling-bolts c of the track. Winn the plate is designed to be applied to a single bolt it can be made in circular or square form, and should have projections or ribs on its under surface toengage the surface against which it bears to preventslipping. In the outer face of the plate is formed a straight tlat channel, d, tangent-to the perforation b and extending out to the margin of the plate, to provide an opening and passage for the insertion of a flattened key, It, between the plate and the nut c, which is placed thereon, engaging the bolt 0. In the bottom of the channel d is formed an oblique recess, 9, extending downward at the side of the perforation I), and at the inner end of the channel is formed as an offset to said recess a notchbearing, h. In the recess is seated the reversely-bent portion 1 of a spring, 8, which extends upward and inward obliquely, its upper end projecting a little above the general surface of the plate. The spring is provided at the end of the reverse bend l with a short an gular arm, a, which, when the reverse bend is sprung into position in the recessseat g, bears against the offset-notch hand holds the spring in firm position against the pressure of the under surface of the nut e. The nutis designed to be radially serrated on its under side, and the angular direction of the engaging end of the springs is backward and upward with reference to the open end of the channel d, so that when the nut is applied to the threaded end of the bolt and turned up the serrations will. pass readily over the yielding end of the spring. When, however, the nut is in position it will be prevented from turning backward by the engagement of the spring with one of the serrations on its under side.

In order to disengage the spring, so as to permit the nut to be loosened, the key It; is introduced into the channel (I and pressed back in between the plate a and the under surface of the not until it engages the inclined face of the spring, pressing it down toward the channel and eti'ecting a disengagement from the base of the nut.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The perforated base-plate having a channel, d, tangent to the pert'oration, a recess, 9, therein, and the oblique spring .9, having a reverse bend, l, terminating in an angularly-bent varm, a, said bend seated in the recess of the plate and said arm engaging an ott'set-notch of said recess, substantially as specified.

2. The combination, with the spring 8, having the reverse bendl and angular arm n, and

the under serrated nut, e, of the perforated plate (1, its open-end channel (I tangent to the perforation, the recess 9, and onset notch h, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ANDERSON D. HOLLAND.
