,nissa NUT LOCK.
Application filed. July 26,
My invention relates to nut locks of the base clutch type wherein friction is utilized in connection with rollers and cam grooves in the nut or washer, for coaction with the part to be bolted, for the purpose of securing the nut in locked position. The invention is applicable for use with a lock nut, as well as for use with a washer that is adapted for use with the usual or standard type of nut.
My invention consists in certain novel combinations and arrangements of parts whereby the cam rollers are retained in operative position at all times, and whereby the cost of manufacture of a lock nut is reduced to a minimum, and the efliciency of the lock nut is enchanced.
In the accompanying drawings, I have illustrated two examples of the physical embodiment of my invention, wherein the locking device is shown as forming part of a lock nut, and also as forming part of a lock washer adapted for use with a standard nut. These exemplifications show the best modes I have so far devised for the practical application of the principles of my invention, but it will be understood that changes and alterations may be made therein within the scope of my claims, without departing from the principles of my invention.
Figure 1 is a face view of a locknut embodying my invention; 7
Fig.- 2 is an edge view of the lock nut partly broken away to disclose the arrangement of the cam grooves and cam rollers;
Fig. 3 is a face view of a lock washer; Fig. 4: is an edge view of the locl; washer; Fig. 5 is a face view of the base portion of the lock nut, or of the lock washer, with the cam rollers and retaining bridges omitted;
Fig. 6 is a view showing one of the rollers; and
Fig. 7 is an end view of this roller. In carrying out my invention, I have illustrated a standard hexagonal nut 1 having the usual threaded bore 2, and provided with a circular base flange 3. In the face of the base flange or base of the nut, I provide a series of spaced grooves t each having a cam wall 5 to form biting faces for the lock nut. In the face of the base, I provide an annular groove 6, and this groove is filled with a ring I or band 7 fashioned of music wire, or other suitable material, and this band of wire, where it crosses the grooves, forms retaining bridges as 7. Preferably. the material of these retaining bridges is somewhat resilient 1927. Serial No. 208,486.
by a hammer to spread the material of the wire or band into the face of the base of the washer, and in this manner the retaining bridges are held across the cam grooves.
Before the retaining ring is fastened in i the face of the base, the cam rollers 9, are placed in their respective grooves, andeach cam roller is provided with an annular groove -7 10 across which the bridge 7 of the retaining ring or band extends. Thus the cam rollers are retained intheir grooves and designed to roll up on the cam faces 5 to cause frictional engagement with a support, when the lock nut is screwed home on a. bolt. I
In Figs. 3 and 4, a washer ll is shown, and this washer is provided with the grooves 4t, cam faces 5, the retaining ring 7 forming the retaining bridges 7 and the same fric tion rollers 9 are used as in Fig. 1 In addition, the washer is provided with spurs or studs 12 that may engage the face of the standard nut, or of the object being bolted, and the action of the cam rollers 9 in con nection with thewasher is the same as the cam action of the rollers with the lock nut. In Fig; 5, the numeral 13 indicates a steel ring or band that may be shrunk or other wise attached on the washer or on the circular base of the nut. The cam grooves 4 and their cam faces may thus be fashioned in the face of the washer or of the base of the nut, before this ring 13 is shrunk or welded on the washer or nut, and in this manner the grooves 4 may be fashioned with simplicity and rapidity. The rollers 9 are loosely retained inthe mortices or grooves 4 until the cam action is brought into play, and then the rollers are free to rollup on the cam face 5 and are guided by the retaining bridge 7 Thering or band 7 is enclosed within the groove 6 as indicated in Fig. 2, .and the band does not protrude beyond the face of the nut base or of the washer. The retaining-bridgeis forced out from the face of the. washer or base of the nut, as the cam roller frictionally engages the surface of the object being bolted, but inasmuch as the roller projects beyond the bridge, the bridge does not interfere with the action of the roller. s
As before stated, various changes and alterations may be made in the construction of iny lock nut Within the scope of my claims without departing from the principles of my invention.
Having thus fully describedniy invention, What I claim as new and desire to secure by Letters Patent is 1. A look nut having an annular groove in the face of its base, and spaced cam grooves in said face, a band of resilient material in said annular groove forming bridges across the cam grooves, and friction rollers in said cam grooves having annular grooves receiving sa1d bridges. p
2. A look nut having an annular groove and intercepting cam grooves in 'the face of its base, friction rollers in said cam grooves having annular grooves, a resilient wire in said annular groove forming retaining bridges for the grooved friction rollers, and means for securing the Wire in the annular groove.
