NUT-LOCK.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed May 12,1906. Serial No. 316.570.

To (ZZZ whom, it may concern.-

Be it known that I, CHARLES D. SMITH, a citizen of the United States, residing at Paris, in the county of Edgar and State of Illinois, have invented a new and useful Nut-Lock,

of which the following is a specification.

This invention relates to nut-locks; and it consists in the novel construction and arrangement of its parts, as hereinafter described.

The object of the invention is to provide a nut-lock especially adapted to be used at the ends of axle-spindles for the purpose of re taining the axle-nuts thereon, although it may be used to advantage when applied to other devices.

It consists primarily of a block adapted to be attached to the end of the spindle, said block having extending vertically therethrough a perforation with oppositelygrooved sides. A pin having at its lower end an enlarged head passes through the perforation of said bloc r, said pin being provided with a spring the end of which are adapted to enter the grooves in the perforation of said block. A cap is secured to the end of said pin on the opposite side of the block from the said head.

In the accompanying drawings, Figure 1 is a perspective view of a spindle, showing the nut-lock applied thereto. Fig. 2 is a vertical sectional view of the block, showing the pin located therein. Fig. 3 is a vertical sectional view of the block with the pin removed. Fig. 4 is a horizontal sectional view of the block. Fig. 5 is a side elevation of the pin disconnected from the block. Fig. 6 is a side elevation with parts in section of the end of the axle, showing the nut-lock applied thereto.

The block 1 is provided on its rear face with the threaded lug 2, which is adapted to enter a thread ed perforation in the end of the spindle 3. The outer face of said block 1 is provided with the integral vertical extending strengthening-web 3. The perforation 4 extends vertically through said block, said perforation being provided at its lower end and on opposite sides with the vertical grooves 5 5. The pin 6 is adapted to slide within the perforation 4. Said pin is provided at its lower end with the enlarged head 7 and at its upper end with the cap 8. The spring 9 passes through the said pin, and the ends of said spring are inclined down toward the head the grooves 10 10, which are adapted to receive the ends of the spring 9. The pin 6 is longer than the dimension of the block 1, as shown in Fig. 2, and the said pin is adapted to slide within the perforation 4 of the said block. The block 1 is so positioned upon the end of the spindle 3 that when the pin 6 is slid up in the said block the axle-nut 11 may pass over the said pin and engage the spindle-threads and when the said nut passes beyond the said pin the same is slid down, which carries the enlarged head 7 below the edge of the nut-perforation, and thus the said nut is held in position against rotation.

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

1. In combinationwith a spindle and a nut, a block adapted to be applied to the spindle end, said block having a perforation, a pin slidably mounted in said perforation and having at one end an enlarged head and at its other end a cap, said pin having greater axial dimension than the block, said pin carrying a spring adapted to engage the block-perforation.

2. In cornbinationwith a spindle and a nut, a nut-lock consisting of a block adapted to be applied to a spindle and having a perforation provided at one end with oppositelylocated grooves, a'pin adapted to slide in said perforation and having at one end an enlarged head and at its other end a cap, a spring attached to said pin and having ends adapted to enter the grooves of said blockperforation.

8. In combination with a spindle a nutlock comprising a perforated block adapted to be attached to the spindle, said block having located in opposite sides of its perforation and at the lower end thereof grooves, a pin adapted to slide within said block-perforati on, said pin having at one end an enlarged head and at the other end a cap, a spring passing through said pin and having depending ends, said pin having grooves located under said spring ends and adapted to receive said spring ends.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
