NUT-LOCK FOR AXLE-SPINDLES.

SPECIFICATION forming part of Letters Patent N0.761,388, dated May 31, 1904.

I Application filed December 5, 1903. Serial No. 183,885. (No model.)

' T on whom it may concern/.-

Be it known that I, EMANUEL S. MORRIS, a citizen of the United States, residing in the city of St. Louis, in the State ofMissouri, have invented certain new and useful Improvements in Nut-Locks 'for Axle-Spindles,"

of which the following is a full, clear,-and exact description, reference being had to the accompanying drawings, forming part of this specification. V

My'invention relates to a nut-lock particularly intended for use to secure the nuts of axle-spindles in a manner that provides for the ready application or removal of the nut while at the same time furnishing aconstru'ction by which the nut is elficiently held from escape while in service.

. The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is. a perspective view of an axlespindle embodying a part of my invention.

Fig. II is a perspective view of the nut that is applied to the spindle shown in Fig. I. Fig.

III is an enlarged longitudinal section of-the' outer end of a spindle and nut embodying my invention and illustratinga wrench by which the nut of my nut-lock may be applied and removed. Fig. IV is a perspective View of the locking-pin of my nut-lock.

- 1 designates a vehicle-axle spindle that is provided with the threaded outer end 2. Inthe outer end of the spindle is a pocket 3, that extends longitudinally of the threaded spindle end, as seen in Fig. III. In this, pocket is a" spiral' spring 4.

5 is a locking-pin that-is provided at its inner end with a head 6, that operates in the pocket 3 against the spring 4. This lockingceive the shank or forward end of the lockingpin 5. The locking-pin is mounted in the end of the spindle in aposition offset from its center, and the aperture in the nut 8 is likewise located in a position offset from the center of the end of the nut and that will correspond to the location of the locking-pin when the nut is applied to the axle-spindle. 1 Any suitable means may be used for applying and removing the nut of my nut-lock. I prefer, however, to use the wrench illustrated in Fig. III, for the reason that it provides means for releasing the locking-pin from the nut at the same time for the rotation of the nut after it is free. This wrenchhas a head A, to be fitted to the nut 8, and is provided with an arm B, bearing a stud C, that is adapted to enter the aperture 9 in the nut 8 to press against the locking-pin 5 and force it forward.

When the nut of my nut-lock is to be ap-' plied, it is screwed onto the threaded end of. g the axle-spindle with readiness until the inner face of the end-0f the nut 8 comes into bearing with the locking-pin 5, thereby causing said pin to be receded against the action of the spring4 that bears thereagainst. As a consequence, unless the locking-pin is repressed fromoutward movement, it'will be projected forwardly and pass into the nutaperture 9. Therefore to force the lockingpin rearwardly and maintain it 'out of said aperture I utilize any suitable implement, such as the wrench illustrated or a nail or other implement in connection with any ordinary wrench. Where the wrench illustrated is used, the stud 0 thereof enters the nutaperture 9 and holds the locking-pin in receded position against the action of the spring 4, and therefore the nut may be screwed entirely home, and when this is accomplished and the locking-pin is relieved of restraint it will be forced outwardly by the spring 4 through the nut-aperture to engage and hold the nut. IVhen the nut is to be removed, the same procedure as that described in connection with this application is gone through with to recede the-locking-pin and hold it receded until the inner face of the end of the of the locking-pin into the nut-aperture, after Which the nut may be readily Withdrawn Without the necessity of holding the lockingpin retracted.

I claim as my invention 1. In a nut lock, the combination of a threaded member, a spring-pressed pin loosely seated in said member projecting from the end thereof, and a nut having an aperture in its end to receive said pin; said pin and aperture being offset from the centers of said threaded member and nut, substantially as set forth.

2. In a nut lock, the combination of a threaded member having a pocket therein extending longitudinally of said member and offset from the axis of the member, a spring in said pocket, a locking pin having, a head seated in said pocket, and resting against said spring, and a box-nut having an aperture in its end ofl'set from the axis of the nut to receive said locking-pin, substantially as set forth.

3. In a nut lock, the combination of a threaded member provided with a pocket extending longitudinally of said member and offset from the axis of the member, a pin having a head loosely seated in said pocket to rest against said spring, a Washer secured to said threaded member encircling said locking-pin, and a box-nut having an aperture in its end offset from the axis of the nut to receive said locking-pin, substantially as set forth.
