Description

C. C. MADISON.
NUT LOCK.
APPLICATION FlLED JULY 28,1915- L230fi45. Patented June 19, 1917.
vJi hwom CHARLES C. MADISON, OF SCANDIA, KANSAS.
NUT-LOCK.
Specification of Letters Patent.
Patented June 1.9, 191'? Application filed July 28, 1915. Serial No. 42,348.
To all whom it may concern Be it knownthat I, CHARLES C. MADISON, a citizen of the United States, residing at Scandia, in the county of Republicand State of Kansas, have invented certain new and useful Improvements in Nut-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to nut locks, and has for its primary object to provide a device of this character of simple and inexpensive construction including means for protecting the portion of the bolt extending outwardly of the nut from the deteriorating action of moisture and the like.
With this and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:
Figure 1 tional view through the improved nut lock.
gig. 2 represents an end elevation thereof, an
Fig. 3 represents a transverse sectional view on the line 3-3 of. Fig. 1.
Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the shank of a bolt of the usual or anyvpreferred construction preferably having a head 6 at one end and external screwthreads 7 extending a distance inwardly from the opposite end. The preferred type of nut 8 is fitted upon the threaded extremity of the bolt shank 5 and is designed to cooperate with the head 6 in the usual manner to clamp an ob ect upon the shank 5.
The threaded extremity 7 of the bolt shank 5 is formed with an inwardly directed longitudinal recess or bore 9 having internal screwthreads extending oppositely to the threads 7 formed externally upon the bolt represents a longitudinal sec-' nal screw threads threads, a
and adapted to receive the externally screwthreaded stem 10 of the hollow locking element 11. The annular flange 12 carried by the lockingelement 11 is of slightly greater internal diameter than the external diameter of the threaded portion of the shank 5 and the inner surface adjacent the edge thereof is beveled outwardly to define a cutting edge 13 adapted to engage the outer face 'of the nut 8 as the locking element is rotated to advance it toward the nut. A pair of diametrically opposed projections 14 are formed integral with the body of the locking element 11 and are adapted to be engaged by a wrench to facilitate removal thereof;
In use, the nut 8 is advanced to' the desired position upon the shank 5 and the hollow locking element 11 is subsequently filled with a heavy lubricant and is advanced by rotating it in the opposite direction to which the nut 8 is rotated until the cutting edge 13 thereof engages and bites into the outer face of the not 8, thus effectively sealing the outer or threaded portion of the shank 5 and simultaneously locking the nut 8 against removal.
What I claim is:
A nut lock including a bolt having exterand a longitudinal bore a nut fitted upon said screw hollow lubricant retaining element fitted on said bolt of greater internal diameter than the latter providing a lubricant containing chamber, said element having its inner edge beveled to provide an angular cutting edge adapted to bite into the outer surface of said closure for said lubricant containing chamber,
or recess,
and a stem earned by said containing element engaged within the bore or recess to lock the nut against removal.
In testimony whereof I afiix my signature in presence of two witnesses.
