UNITED STATES PATENT orrion LAWRENCE M. GALLIHER, OF LEXINGTON, MISSISSIPPI, ASSIGNOR OF ONE-HALF TO J. S. CARROLL, OF HAYS COUNTY, TEXAS.
SELF-LOCKENG NUT.
Specification of Letters Patent.
Application filed April 7,1905. Serial No. 254,293.
- new and useful Improvements in Self-Locking Nuts; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates tonew and useful improvements in nut-locks and the object of the invention is to produce a simple and efficient device of this nature in which the nut has a chambered portion for the reception of a tapering flexible key adapted to sit against the inclined wall of the chambered portion, a portion of the key being adapted to be held in a groove of the face of the nut.
The invention consists, further, in various details of construction and in combinations and arrangements of parts, which will be hereinafter fu ly described and then specifically defined in the appen'ded claim.
My invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspectiveview of my nutlook as applied to a bolt. Fig. 2 is asectional view longitudinally through the nut. Fig. 3 is a face view showing the d vice of the lock-' ing-key seated in the cham ered portion of the nut. Fig. 4 is a detail perspective of. the locking device, and Fig. 5 1st, detail view of the nut.
Reference .now being had to the details of the drawings by letter, A designates a nut having a centrally-threaded aperture therein, one face of said nut being chambered out, as at C, the inner end of the wall of the cham-- bered portion being beveled, as shown at D, and E designates a groove formed in one face of the nut, preferably at the corner thereof, and at the lower marginal edge of said groove terminating at the upper end of the beveled part of said chambered portion.
F designates a locking-key made of resilient material, is partially coiled, and has a beveled circumference K; One end of said key is outwardly bent and adapted to be the inner face of said key has serrations N, which are designed to bite into the threads of the nut, as the latter is secured upon the threaded end of the bolt, thereby causing the nut to be securely held from rotation. The serration nearest the end of a key projects slightly beyond the other serrations for the purpose of securely gripping the threads of the bolt.
by means of a wrench, and as the inner edge the diameter of the key will be contracted, causing the inner edge of the key to securely bind and engage the bolt. If preferred, the teeth upon the key may be dlspensed with and a single ointed portion bolt.
From the fore oing it will be observed that a simple and e 'cient device is provided for may be readily applied to or removed therefrom.
While I have shown a particular form of tures of my invention, it will be understood thatI may vary the detailed construction of the same, if desired, without in any way departing from the s irit of the invention.
\ Having thus fuly described my invention, what I claim as new, and desire to secure by Letters Patent, is A nut-lock comprising a nut with a central threaded bore extending substantially half the thickness of the nut, the threads of said bore terminating in a chambered or recessed ortion with inclined walls, with a channel eading through one'corner of the nut from said recessed portion, a resilient key which is circular outlined and provided with an inclined outer circumference conforming to the inclined wall of the chambered portion of the nut, 'one end of said key being bent at right angles anddesigned to engage the channel Patented March 6, 1906.
