Specification of Letters Patent.
atented Feb. 26, 1907.
Animation nei october 8.1906. semi No. 338,008.
lSe it known that l, (nxiiLus ll.. llionns, a citizen ol` the United States, residing at Q llossburg, in the county of Darke and State oll Ohio, have invented anew and useful .Nut- Lock, ol which the following is aspccilication.
'.lliis invention has relation to nut-locks; and it consists in the novel construction and arrangement olE its parts, as hereinafter shown and described.
rlhc object oll theI invention is to provide a simple. ellective, and positive locking mechanism ulu'ireby a. nut may be attached to a bolt and the possibility olz the saine unscrewing incidental to expansion and contraction of metal or to jarring is prevented. The invention consists primarily of a key, which is provided with an annular portion adapted to surround the bolt and which lits within a recess provided in the under face of the nut. The said under face of the nut is provided with a radially-extending recess which receives the radially-extending arm of said key. The outer end' of said arm is adapted to engage notches provided in a washer or may cnter a detent formed by any suitablel implement in a metallic surface against which the nut is screwed.
In the accompanying drawing, Figure 1 is a perspective view of a bolt-,showing the nut and washer applied thereto. Fig. 2 is aside elevation of the bolt, showing the nut, k'ey, and washer in section. Fig. 3 is a perspec-A tive view of the key. Fig. 4 is a perspective view of the under side of the nut, and Fig. 5 is a top plan view ofthe washer.
The bolt 1 is of usual formation. The nut 2 is provided in its under face with the annular recess 3, the side wall of which is pitched at an incline. The radially-extending recess 5 enters at its inner end the said annular re? cess 3, and its outer end is located at the corner 6 of the nut. The top wall of said recess The key consists of the annulus 7 which is adapted to surround' the bolt 1 and lit within the recess 3 of the nut 2. The outer Wall 8 of said annulus is beveled or inclined at a degree corresponding to that of the side 4 of the recess 3. The finger 9 extends laterally and radially from the annulus 7 and is slightly reduced in vertical thickness toward its outer end 10. Said outer end ofthe inger 9 is bent down, as indicated in Fig. 2, and is twisted slightly along its longitudinal axis, as indi cated at 11 in Fig. 1. The Washer 12 is provided in its face with a number of notches 13 each said notch being provided with a radif is located at an acute angle to the face of the washer. The said notches 13 are adapted to receive the end 1t) ol the linger 9, the said nger being twisted along its longitudinalaxis in order to lit snugly within the said notches.
The washer 12 is held in fixed position upon the backing material 17 by means of the indentation 16, provided in its under side, which are'adapted to receive elevated. portions of the said backing 17. The Washer 12 is generally employed when the backing 17 is composed of wood. Consequently as the said washer is forced against the fade of the said backing the iiber ol the Wood is forced up into the recesses 1-6 and retains the said washer against rotation.
When the nut-lock is used in connection with a backing 17 composed of metal, the washer 12 is not used; but when the nut 2 is tightened upon the bolt a detent is made in the vlace of the backing 17, a cold-chisel being used for this purpose, and the end .10 of the `linger 9 is permitted to enter said detent.
When it is desired to remove the nut 2 from the bolt l, an implement is inserted under the end 10 oi the linger t), and the said end 10 of the said linger is brought up until its lower edge is above the edge oi' the detent (not shown) orabove the edge of the notch 13 in the washer 12, when the nut 2 may be readily unscrewed.
llaving described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A mitdock consisting of a bolt, a n ut having a bolt-perforation with an annular recess located at the end thereof, said recess having an inclined wall and a radially-extending recess extending froin said annular recess to the edge of the nut, a key having an annular portion adapted to rest within said IOO annular recess. said annular portion having a beveled outer wall, said key having a finger resting in said radially-extending recess of the nut and adapted at its outer end to enter a notch or detent.
2. A nut-lock consisting of a bolt, a nut having a bolt-perforation, an annule? recess located at the end of said perforation and a radially-extending recess extending from the said annular recess to the corner of the nut,
