NORHXS PETERS 0a,. mo'rouruo. WASHI N D STATES PATENT BENJAMIN F. KEYSER, OF QUINCY, KENTUCKY, ASSIGNOR OF ONE-HALF TO BENJAMIN I CONWAY, OF COVINGTON, KENTUCKY.
NUT-LOCK.
SPECIFICATION formingpart of Letters Patent No. 630,715, dated August 8, 1899. Application filed April 4, 1899. Serial No. 711.725. (No model.)
To all whom it may concern: i
Be it known that I, BENJAMIN F. KEYSER, a citizen of the United States, residing. at Quincy, in the county of Lewis and State of Kentucky, have invented new and useful Inn-, provements in Nut-Locks, of which the following is a specification.
This invention relates to improvementsin nut-locks of that type in which a locking-key is used, said key engaging with the bolt and n ut so as to hold the nut against rotation; and the general features of my invention consist in the combination, with a nut and a recessed bolt, of a locking-key which is adapted to engage with the recesses in thebolt andimpinge against the top of the nut, so as to hold the nut against rotation in one direction and the key from displacement, the key being of such configuration thatit will straddle the bolt and embrace it between the recessed portion thereof and the nut, as will be hereinafter set forth.
In the accompanying drawings, which illustrate my invention, Figure l is a side elevation of the bolt, the nut and locking-key being shown in section, said locking-key being placed in the position it will occupy prior to being driven home to lock the nut. Fig. 2 is a side elevation, the key being in position to lock the nut. Fig. 2 is a longitudinal section taken through partof the bolt, so as to intersect the recesses formed therein. Fig. 3 is a rear elevation of the key; Fig. at, a perspective view of the key, and Fig. 5 a vertical section through the bolt.
In the drawings, Arefers to a bolt which is provided on opposite sides with recesses a; a, the recesses being of such an inclination with respect to the length of the bolt that the threads will intersect the side walls, so that the nut may travel on the threads without interruption.
when viewed from the side, and the side Walls a are practically straight, the inclination- The side walls a of the re cesses nearest the end of the bolt are convex,
end walls of the recesses are undercut or dovetailed, as shown in Fig. 2 of the drawings. I
The locking-key B has a concave face and is partially divided by a slit 1) of substantially -the same width as the Web of the bolt, and
the members on each side of the slit taper therefrom to the sides or outer edges of the key, making each member wedge-shaped in cross-section to correspond with the dovetailed recesses in the bolt, and the front and rear walls of the key are practically parallel. The upper portion or head I) of the key extends considerably. to the rear of the slitted part thereof and is recessed or hollowed out so as'to provide depending sides B, which will straddle or overlie the bolt, and the semicircular recess in the head will bear upon the bolt.
In operation when the bolt and nut have been placed in position for use the bifurcated end of the key is placed over the web, so as to lie partially in the recess, the rear edge of the head then being practically on a line with Y the top or outer face of the nut. When the key is forced home, the inner portion of the head will impinge upon the nut and hold the same against rotation, which would move it toward the outer end of the bolt, and at the same time the key will be locked by engagement with the nut, so that it cannot be readily removed. When it is desired to form a permanent lock, the points which depend from the side pieces of the head may be bent so as to embrace the bolt, and thereby prevent the removal of the key.
It will be noted that the inner portion of the head of the locking-key engages with the nut and that the configuration of the recesses in the bolt and the bifurcated portion of the key is such that the key when inserted will assume an inclined position and the dovetailed recesses will prevent the bifurcated portion of the key spreading.
one of the walls of the recess convex and the other wall straight and curving the parts of the locking-key which engage therewith the key can be readily inserted and; the inner portion will be brought to such a position that it will bite the top of the nut.
By making 1 I am aware that prior to my invention it has been proposed to look a nut upon the bolt by the use of a bifurcated key or staple, the bolt and nut being recessed for the reception of a locking-staple.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a nut-lock, the combination with a bolt having recesses disposed obliquely to its long diameter, of a locking key bifurcated to enter the recesses and cause a portion of the key to impinge against the top of the nut to hold the same against rotation in one direction and to retain the key upon the bolt, substantially as shown.
2. I11 a nut-lock, the combination with a bolt having inclined recesses, the walls thereof nearest the head of the bolt being straight, the other walls beingcurved, of a locking-key bifurcated to enter the recesses in the bolt, said keyhaving a head which projects toward the nut, substantially as shown.
3. In a nut-lock the combination with a bolt having side recesses which are disposed obliquely to its long diameter, a nut mounted thereon, of a locking-key having a portion adapted to enter the recesses in the bolt, a rearward -extending head and side pieces which are adapted to overlie the bolt, substantially as shown.
4. In a nut-lock, the combination with a bolt having inclined recesses which are dovetailed or undercut, a nut mounted on the bolt, of a locking-key having a rearwardlyi extending head and bifurcated portion which extends therefrom, the side members of the bifurcated portion being wedge-shaped substantially as shown.
5. In a nut-lock, the combination with a bolt having on opposite sides inclined and dovetailed recesses the walls of the recesses nearest the end of the bolt being convex, of a locking-key which is slitted longitudinally, the portions on each side of the slit being wedge-shaped in cross-section, said key being curved longitudinally and provided with a head which extends rearward of the curved slitted portion, depending side pieces of a greater length than the diameter of the bolt, substantially as shown.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
BENJAMIN F. KEYSER.
