LOCK-NUT.
SPECIFICATION forming part of Letters Patent N o. 236,644, dated January 11, 1881.
Application filed June '1, 1880. (No model.)
My invention relates to lock-nuts for useupon railway fish-bars, or in any other` locality where the nuts are liable to work loose.
My invention consists, essentially, in forming the nut with a thin projecting iin upon its lower edge, a portion of which may be struck into a recess or groove in the surface of the sh-bar or other object when the nut has been run down to its seat.
In the drawings, Figure I is a separate View of the lock-nut. Fig.- II shows the same in use with a ish-bar 5 Fig. III, a cross-section through the ndl't'ted portion of the nut and bar.
A is an ordinary nut, except that a n, A', is formed upon its lower surface, so as to project out therefrom. B is a bolt; C, a fish-bar or other surface down against which the nut is to be run, and provided with a groove, indentation, or recess, C', adjacent to the bolt.
The operation of the device is as follows: The nut having been run down upon the surface C and firmly seated, the operator, with his wrench or a suitable tool, strikes the edge of the 1in into the grooveor indentation, thereby tirmly locking the nut.
I prefer that the indentation or groove shall be shallow and with bcurved edges, so that when a portion of the iin is projected into it the nut will be held against all liability of working loose and against accidental displacements; but should it be desired to loosen or tighten the nut the indented portion may be caused to ride up out of the groove or recess by a smart turn of the nut by a wrench.
I am aware that a separate washer with one edge turned up so vas to cause the washer to turn with the nut has been employed, andthe same locked by striking its edge into a groove 5 but the construction requires a separate washer, while by my device the nut and iin accomplish the same purpose, and, being made in a single piece, are cheaper and more convenient.
If employed upon wood or upon a smooth object, the indentation may, at the time of using, be made with asuitable tool and the fin be struck into it.
In Fig. IV is represented a method otmaking the nut with a iin on each of two edges, and is made by rolling; and I would have it understood that the iin may be upon one or more sides of the nut, or may extend all the way around it.
What I claim is- The combination, with a fish-bar having a groove or recess, of a bolt and a nut with a projecting iin on its lower edge, adapted to be 'locked by striking the edge ofthe fin into the groove, substantially as described.
In testimony whereof I sign this specication in the presence of two witnesses.
