NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 603,050, dated April 26, 1898.

Application filed December 2'7, 1897. 1'ia1 663,605. (No model.)

To ctZZ whom it Hwy concern.-

Be it known that I, J UsTIN B. SARGENT, a citizen of the United States, residing at WVest Lebanon, in the county of Grafton and State of New Hampshire, 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 invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in never-slip nut-locks which are particularly adapted for use upon bolts used in vehicle construction or any place where my nut-lock will perform its functions.

The main object of my invention is the provision of a nut-lock for the purpose named which is very easily applied to any bolt, which will not allow the nut to become loose, and which is very simple and durable, as well as cheap, thus producing a much-needed device of this character.

To attain the desired objects, the invention consists of a nut-lock embodying novel features of construction, substantially as shown in the drawings and described herein.

Figure 1 represents a perspective view of my improved nut-lock in position for use, the bolt and nut being shown in dotted lines to more clearly show the construction of the lock. Figs. 2, 3, and i are sectional views of some modified forms of my nut-lock, and Figs. 5, 6, and 7are perspective views of other modifications.

In the drawings, A designates the bolt, having the head and screw-threaded end common to all bolts, and B designates the nut, which is adapted to screw upon said bolt, and to keep this nut in a rigid position I employ my improved nut-lock, which consists of the plate 0, whose body portion is curved or arced, as D, from end to end to form a spring to press upward against the bottom of the nut. In the body portion is the circular opening E, through which passes the end of the bolt, the nut being placed upon the bolt after the plate. The plate is formed with the bent end or prong F, which is bent downward to keep the plate from turning upon the surface of the object G, through which the bolt passes, and to doubly secure the nut against turning the plate has another corner bent upward to form the bent end or prong H, which is bent upward to abut against the side of the nut.

In Figs. 2, 3, and 4; it will be seen that I employ the bent up side J instead of the prong II. In Fig. 2 the side K is bent at right angles to the plate to perform the same functions as the prong F in Fig. A prong L is formed upon the plate, which is adapted to be forced into the surface of the object and hold the plate from turning, and in Fig. 4 the two prongs M are formed upon the plate for the same purpose as the prong L, but to more securely hold the plate in position.

In Fig. 5 instead of the prongs L or M an opening N is made in the plate, in which is placed a nail or pin 0 to answer the same purpose as the prongs, the nail being driven in the surface of the object.

In Fig. 6 a strip P is cut from the body of the plate and has the curved upward portion I which is adapted to abut against the side of the nut to guard against its turning, and in Fig. 7 a short strip Q, is bent upward from the body portion of the plate to answer the same purpose as the strip P. I provide the nut on the under face with grooves R, with which engages a raised portion S on the locking-washer.

From this description, taken in connection with the drawings, it will be seen that my nut-lock is easily applied and used upon bolts upon vehicles, such as whiftletree-bolts and the like, it has no equal, will hold the nut and prevent its turning, and that the lock is very simple, durable, and cheap, thus making it a useful and practical article.

I claim- 1. In a nut-lock, the combination with the nut having a groove or grooves on the under face, of a plate having a lug to engage the groove and also having one end bent to engage the nut on its outer edge.

2. In a nut-lock, the combination of the nut having a groove or grooves on its under face, of the curved spring-plate having its ends bent in opposite directions to engage the nut and base-plate and having a lug for engaging the groove of the nut.

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