JAMES (J. HOLLOWAY, OF SAN FRANCISCO, CALIFORNIA.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 564,750, dated July 28, 1896.

Application filed January 20, 1896. Serial No. 576,206. (No model.)

T to whom it may concern.-

Be it known that I, JAMES C. HOLLOWAY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Nut-Locks and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a nut-lock; and it consists of the parts and the constructions and combinations of parts which I shall hereinafter fully describe and claim.

In the accompanying drawing the figure represents my invention as applied to railway fish-plates.

In said drawing, A indicates a plate of thin metal having an opening or openings made through it for the passage of a bolt orbolts and having projecting wings B cut from within and out of the body of the plate and contained within the outer wall or edge thereof. These wings are designed to be bent or turned outwardly in such a manner that they may be made to lock or secure the nut.

In the drawing the invention is shown as applied to the nuts of railway fish-plates, although it is not limited to this particular use. The fish-plate is shown as having two openings, one ,near each end, at such a distance apart as to receive the two bolts which are used, said bolts passing through said holes and having the plate A fitted over them. When the parts are thus assembled, the nuts are screwed down upon the threaded ends of the bolts until they are sufficiently tight against the plate, when the projecting wings B are bent or turned outwardly against two of the sides or faces of the nuts. As the nuts must be frequently tightened I have formed supplemental lugs or spurs 6 upon the edges of the wings and formed integral with the latter, and cut from within and out of the hand.

body of the plate and contained within the outer edge thereof, and these lugs are designed to be turned at right angles with the wings, so that they may be made to engage the two remaining sides or faces of the nuts when the wings have been turned up but a little way. The plate A, which is preferably of mild or malleable steel or iron, can be bent several times without breaking. WVhen the wings and lugs are bent to engage the nuts, as described, the latter will be securely held after they have been turned to the proper point.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A nut-lock consisting of a sheet of metal having wings provided with integral supplemental lugs on opposite sides, said wings and lugs being cut from within and out of the body of the blank and contained within the outer wall or edge thereof, said wings adapted to be bent to engage two of the sides of the nut and said lugs adapted to be bent at right .ngles to the wings and to engage the two remaining sides of said nut.

2. In a nut-lock, a plate perforated to receive the bolt, and having a wing on each side of the bolt-hole, with integral supplemental lugs, said wings and lugs being cut from within and out of the body of the plate,

and contained within the outer wall or edge thereof, said wings adapted to be bent to engage the side walls of the nut and said lugs adapted to be bent horizontally inward, toward each other, and to engage the top and bottom walls of the nut.

In witness whereof I have hereunto set my JAMES C. HOLLOWAY. WVitnesses:

S. H. NoURsE,
