lIMPROVEMENT IN NUT-LOCKS.
Specification forming part of Letters Patent No. 221,814, dated November 18, 1879; application filed i I March 17, 1879.
To all whom it may concern:
Be it known that I, ROBERT HAZLEwooD,
of the town of Moundsville, county of Mar-` specification.
The object of my invention is to provide a mechanical device that will securely lock a nut in its desired" position on a screw, and also at the same time allow the nut to he easily screwed on or off when desired.
My invention consists in the arrangement whereby a projection of a key within the nut, operated by a spring', enters a longitudinal groove iu the screw, and thus locks the nut.
In the accompanying drawings, in which similarletters of reference indicate like parts, Figure l is an end'view, and Fig. 2 a side View, of a screw and nut embodying my invention, the nut screwed on and locked. Figs. 3 and 4 are views, respectively, of the nut and screw, each separate and unserewed from the other. Fig. 5 is a section ofthe nut on line H K without thekey andspring. Fig. 6 is a section of the nut on line L I through the key and spring. Fig. 7 is a view of the spiral spring. Figs. S and 9 are, respectively, side` and end views of the key.
Within the nut A is the key N, with a Aprojection, E, and a thumb-piece, D, around the said key N. `Under the said thumb-piece D is tted a spiral spring, C. The screw B has one or more longitudinal grooves, I, into which the said projection E of the said key N tits, and locks the said nut A in its desired place on said screw B;
The opera-tion otl the device is as follows: In
-screwing on the nut the thumbpiece D of the key N is pressed in until the projection E of key N is withdrawn far enough not to interfere with the revolutions of the nut A on the screw B. The said thumb-piece D of said key N is held in this position by a wrench, or otherwise, and the nut screwed on, in the usual manner, as far as desired, when the pressure is removed from the said thumb-piece D of the said key N, and the spring C, `pressing upon the under side ot' said thumbpiece D of said keyN, pushes it back to its original position, causing said projection E of said key N to enter the longitudinal groove I of said screw B, thus locking said nut Ain it's desired position on said screw B.
To remove the nut, the said thumb-piece D of said key N has only to be pressed in and held there, as in putting it on, and the said nut A unscrewed in the usual manner.
What I claim is- In a nut-lock, the combination of a screwboit having the groove I with the nut A, having an opening entirely through it to receive the key N, which is provided with the point E and thumb-piece D, and the spring C, the part-s heilig arranged for operation substantially as shown.
his ROBERT HAZLEWOOD.
