NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 268,180, dated October 17, 1882.

Application filed March 28, 1882.

T 0 all whom it may concern:

Be it known that I, WILLIAM P. MiLLER, of Tipton, in the county of Moniteau and State of Missouri, have invented a new and Improved Nut-Lock, of which the following is a full, clear, and exact description.

My invention relates to. improvements in nut-locks; anditconsistsiu anovel construction and combination of parts, as hereinafter more fully set forth.

The plate to which the swinging plate is hinged is provided with two spring-tongues having guide-loops at the ends, between which a hinged joint on the swinging plate passes, this hinge-joint being provided with a cam, projection, by means of which and the springtongues the swinging plate can be held in any desired position.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding pa'rts in all the figures.

Figure 1 is a perspective view of my improved nut-lock, showing the hinged recessed plate swung outward orraised. Fig. 2 is a. front elevation of the same, showing the hinged recessed plate swung down on the fixed plate. Fig. 3 is a sectional plan view of the same on the line w 00, Fig. 2, the hinged recessed plate being swung outward.

The plate A is provided near one end with an aperture to drop over the threaded end of the bolt B, and with two longitudinal slits,

from the other end, forming theoutertongucs, (J, and a middle tongue, D. The outer ends of the tongues O are bent to form hinge-loops O, or are bent around the ends of a pivot, K, projecting from the ends of a hingeloop, H. The middle tongue, D, is provided with an aperture, D, near the point, through which aperturea screw or nail or stud is passed into the object on which the plate A is held, to prevent the plate A from turning on this object. A plate, E, is provided at one end with a recess, F, slightly larger than the nut G, and at the opposite end this plate E is provided with a central hinge-loop, H, fitting in between the hinge-loops O O. The plate E may be cast with a pivot projecting ateach end of the middle part, H, of thejoint for taking the place (Model.)

of the pivot or pintle K; or the hinge may be constructed in any other suitable manner, so that the two parts will not be disengaged. The outer end of the hinge-joint H is provided with a squared camprojection, J, resting against the middle tongue, D, of the plate A. The plate E is held in place,when raised or folded down upon the plate A, by the squared cam-projection J resting against the middle tongue, D, of the plate A, and by the tongues 0 being flexible and bearing upon the pivot of the hinge.

The plate E may be provided with an aperture in place of the recess F.

The bolt B having been passed through the object, the lock is applied by haviugthe plate E raised, and the aperture in the plate A being dropped or placed over the protruding or threaded end of the bolt B. Then the nut G is screwed on the threaded end of the bolt, and is turned down tight upon the plate A, and is then in position to receive or pass into the recess F in the plate E when this plate is folded down and resting upon the plate A, thus preventing the nut from turning, and thereby locking it.

l have described the look as applied to one nut; but it can be made for two or more nuts above or in line with each other.

I may make the-outer tongues, O, fixed and the middle tongue, D, a spring-tongue, and in this case this tongue D must be provided with a hinge-loop, and the two hinge-loops on the plate E, at each end of the hinge-loop ot' the tongue 1), must be provided with can1-pr0jections; but this construction is a. mere colorable variation of the construction shown, which is preferred.

I am aware that a nut-lock consisting of a hinged locking-plate provided with a projection at one end, and pivoted to a spring connected to the fish-plate, which spring acts upon said projection and holds the plate in position, has heretofore been employed, and[ therefore lay no claim to such construction, my invention being confined to the construction pointed out in the claim.

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

In a nut-leek, the plate A, provided with a ing' cam-projection J and the pintle K, subbolt-hole at one end, and at its opposite end stantially as and for the purpose set forth. with the tongues 0, having" sleeves O at their ends, and intermediate spring-tongue, D, the WILLIAM MILLEI 5 said spring-tongue being integral with said I \Vitnesses:

plate, in combination with the plate I pro- CYRUS O. 1\IACLAY, vided with the recess F, and the sleeve IT, hav- 4 JOSEPH F. TAYLOR.
