SPECIFICATION forming part of Letters Patent No. 237,982, dated February 22, 1881.

Application filed September 28, 1880. (No model.)

To all whom it may concern: the slot fitting the bolt, said bolt and nut are Be itknown that I, HUGH S. JOINES, a citiheld fast without possibility of turning. zen of the United States, residing at Santa Fe, The device is very simple in construction, in the county of Santa Fe and Territory of easy of application, and efficient in use. 5 New Mexico, have invented certain new and The boltA having been passed through the useful Improvements in NutLocks and I do articles to be secured, the nutBis screwed therehereby declare the following to be a full, clear, on to the proper position. The cap (l is then and exact description of the invention, such as placed over the projecting end of the bolt and will enable others skilled in the art to which it forced down into close contact with the face of 10 appertains to make and use the same, reference the nut, and the inwardly-turned flanges d, by being had to the accompanying drawings, and the same movement, pressed over the edges of to letters or figures of reference marked therethe nut and sprunginto the beveled sides thereon, which form a part of this specification. of, where they are firmly held bytheir spring- This invention consists in a nut having each like action and the peculiar form of the sides 15 of its four outer sides beveled or recessed, and of the nut, and as the edges of the slotted pora sheet-metalcap or washer having at each end tion of the cap bind against the flattened porau inwardly-turned flange, to engage with the tion of the bolt, both the bolt and nut are sebevels on two sidesof the nut, andaslotthrough curely held from turning so long as the cap rewhich the end of the bolt projects, the bolt bemains in position.

In this construction the nut B gradually tapers from the top to near the bottom, where such taper terminates in a groove or recess, 1). The sheet-metal cap 0 has an elongated slot, 0, as in the before-mentioned construction; but in lieu of the downturned corners of the cap resting upon and embracing the edges of the nut, as in Fig. 1, they may extend beyond said edges, as shown in Fig. 4., so as to be out of close contact with the nut at those points, and at the same time increase the facility with which said cap may be removed, as the space in which the raising-tool would be inserted is larger than in the preceding example. The flanges d are inturned, as in the other construction, and spring into recesses I) in the sides of the nut.

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

1. The nut B, having its outer sides beveled or recessed at b, and the sheet-metal cap 0, slotted at c, to receive the bolt, and having inwardly-bent flanges d d, to engage with said beveled nut, substantially as and for the purpose set forth.

2. The combination of an irregularly-shaped bolt, A, nut B, having beveled sidesb, and the cap 0, having slot 0 and inwardly-bent flanges cl, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HUGH S. JOINES.
