UNITED STATES WILLIAM o. ALTHEN,

PATENT Orric OF COLUMBUS, OI-IIO.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 599,980, dated March 1, 1898.

Application filed March 22, 1 8 9 '7.

To aZZ whom it may concern:

Be it known that I, WILLIAM C. ALTHEN, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Nut-Locks, of which the following is a specification.

My invention relates to the improvement of nut-locks, and has particular relation to the improvement of that class of nut-locks shown and described in my former letters Patent No. 578,591, dated March 9, 1897.

The object of my present invention is to combine with a nut-lock of the class mentioned superior and improved means for retainin g the lockin g-disk against voluntary rotation and in desirable engagement with the end of the spindle of the vehicle 011 which the nut-lock is adapted for use. This object I accomplish in the manner illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of a portion of a wagon-spindle having my improved nut-lock in connection therewith. Fig. 2 is an end view of the spindle, showing the nutlock thereon. Fig. 3 is a side'elevation of the locking-disk which I employ, as hereinafter described. Fig. 4 is a view taken from the opposite side from that shown in Fig. 3. Fig. 5 is an inner face View of the lockingdisk; and Fig. 6 is a detail view in elevation of the outer end portion of the spindle, showing the locking-disk in engagement therewith, the adjoining and other parts being removed for the sake of clearness in illustration.

Similar letters refer to similar parts throughout the several views.

(1 represents a vehicle-spindle, the threaded outer end portion of which is adapted to receive a nut a in the usual manner. This outer end of the spindle is provided with a cross-recess a preferably of that character which is ordinarily produced by a chisel or other similar sharpened tool.

1) represents one of the parts of my improved lock which is in the form of a disk and which is provided with a continuous peripheral groove 1). The forward face and upper side of the disk I) has formed therein a short way or channel a, which leads into the groove Z), while a similar way or channel dis formed in the lower side of the disk I) and Serial No. 628,698. (No model.)

also communicates with the groove 1). Adjacent to the opening cl the groove or channel b is provided in its inner wall with a recess e. Adjacent to the opening 0 the inner wall of the groove Z) is provided with a shoulder 6. As indicated in the drawings, the inner line or wall of the groove 1) extends to the recess (2 in a slightly-inclined direction.

The inner end or face of the disk I) has formed thereon,as shown more clearly in Figs. 5 and 6 of the drawings, an outwardly-projecting rib 6 which crosses said disk-face and intersects the central opening 6 therein. This projecting rib, as shown more clearly in Fig. 6 of the'drawings, preferably has its sides inclined or formed flaring.

Through the central opening of the disk I) is adapted to pass the usual axle lag-screw f, the head of the latter bearing against the outer face of the disk I) and retaining said disk against the end of the axle-spindle. In this position the recess or groove (1 of said spindle is adapted to receive the projecting rib e of the disk.

g represents a locking-ring the inner surface of which is provided, as indicated more clearly in Fig. 2 of the drawings, with oppositely-located inwardly-projecting lugs g This ring 9 is, as indicated in the drawings, adapted to embrace the disk I), the lugs g and g gaining entrance to the groove I) through the medium of the ways 0 and d. The lugs having thus been made to enter the (llSl=-%5' groove 1) the locking-ring is turned,:$iownward, thelugs g and g traveling in the groove b until the lug 9 drops into the recess 6 on the under side of the disk and the lug g is against the shoulder e of the upper side of the disk.

As indicated in the drawings, I preferably provide the ring g on one side, which becomes the lower side when said ring is in the locked position, with a stem h, which serves partly as a weight to retain the ring in a locked position and indicates to the eye whether or not said ring is in a locked position.

On the inner face of the ring 9 and in the upper portion thereof I have provided a forwardlyprojecting boss or lug it, which is adapted to come into contact with the outer face of the nut to in case the latter is screwed inward past the outer-end of the spindle.

While the construction shown in my said former patent ordinarily operates to prevent any possible rotation of the disk against the axle-spindle, it is evident that by providing the disk with the cross-rib e and providing the spindle with the receiving-recess a any tendency toward such voluntary rotation is entirely obviated, and the position of the disk with reference to the axle-spindle is assured.

From the construction and operation which I have described it is obvious that a simple, efiective, and inexpensive nut-lock is provided which may be employed in connection with any of the ordinary constructions of wagons. It is also evident that by the use of my improved locking device any tendency of the nut toward working off the spindle is obviated and that said nut must retain its place on the spindle until the ring g is inverted and detached from the disk 1).

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

1. In a nut-lock the combination with a spindle having an end groove or recess a formed therein, a nut adapted to screw on said spindle, and a disk secured against the end of said spindle, the body of said disk being out of contact with said nut, said disk having a projecting rib adapted to enter said spindlerecess, of a lag-screw passing over said disk and entering said spindle, substantially as and for the purpose specified. V

2. In a nut-lock the combination with a spindle havinga cross end recess a formed therein and a nut adapted to be screwed on said spindle, of a locking-disk secured against the end of said spindle, said locking-disk having a projecting rib adapted to enter said spindle end groove, a peripheral groove in said disk and oppositely-located ways leading to said groove and a ring 9 having oppositely-located lugs, the latter being adapted to enter said disk-groove through the medium of said ways, substantially as and for the purpose specified.

WILLIAM C. ALTHEN.
