NUT-LOCK.

SPECIFICATION formingpart of Letters Patent No. 656,151,dated August 14, 1900.

To all whom it may concern:

Be it known that I, MILTON BARTLEY, a citizen of the United States, residing at Polk, in the county of Venango and State of Penn- Sylvania, have invented certain new and usef ul Improvements in Nut-Locks, of which the following is a specilication, reference being had to the accompanying drawings, forming part of thisspecitication, in which* Figure lis a partial side elevation of a railjoint, illustrating the application of my nutlock. Fig. 2 is a crosssectional View indicated by the line II II of Fig. 1. Fig. 3 is a horizontal sectional View taken on the line x5 III III of Fig. 1. Figs. .tand 5 are perspective views of the lock detached.

My invention consists of an improvement in devices for preventing nuts from loosening by turning, and is designed to embrace zo the sides of the nut and to beheld in immovable engagement with the fish-bar or other member upon which the nut is secured. I have shown it applied to the Well-known rail- `joint, which is one of the chief sources of z 5 trouble with loose nuts.

Referring now to the drawings, 2 is the rail, the ends of which are connected by the usual sh-plates 3 3 and bolts 4. Extending upwardly from the bolt-hole of the fish-plate on 3o one outer side is a depression or groove 5,

which may, however, be made in other directions, if desired, although I prefer the position indicated for the reason that the groove is thus located immediatelyunder the edge of the rail-head and for the further reason that the effect of gravity is thus utilized to maintain the lock in position.

The lock consists of a rectangular clasp made of a band or bar of metalhaving a mid- 4o dle portion 6 and side portions 7 and 8, so ar-4 ranged parallel to each other as to embrace the sides of the nut when' the lock is in position. Either or both of the sides 7 and 8 is made sufficiently long tol project beyond the y corner of' the nut and to be bent around it,

as vclearly shown in Fig. 1. Extending outwardly and downwardly from the back of the Application filed February 9, 1900. Serial No. 4,640. (No model.)

to be an eflieient, simple, and reliable lock to prevent dislodgment of the nut. Its removal is easily effected by turning out the end 10 and prying the clasp out of engagement with the groove, when the nut may be removed.

The lock may be made of forged iron or malleable casting, while the grooves 5 may vberolled or pressed in the fish-bar originally or may be easily made by suitable tools on old bars already in position.

The advantage of my invention will be appreciated by those skilled in the art, as it is very simple, easy to make and use, cheap in cost, and reliable in action, and in actual service has demonstrated its efficiency for an extended length of time.

.Having described my invention, what I claim is- 1. A nut-lock consisting of a rectangular clasp, one or both sides of which are adapted to be bent around the corner of the nut, and a lug projecting outwardly from the back, and with an inwardly-extending face on a plane with the inner edges of the clasp, substantially as set forth.

2. In combination with a fish-plate provided with a retaining-groove, a rectangular clasp adapted to embrace the sides of a nut and a backwardly-projecting lug adapted to engage the retaining groove land to bear against the inner face ot' the nut, substantially as set forth.

3. In a nut-lock, the combination of a fishplate or member provided with a bolt-hole, a groove in the face of the plate extending out- In testimony whereof I ax my signature in presence of two Witnesses.

MILTON BARTLEY.

wardly from the bolt-hole, a clasp formed of a Het metallic bar bent; to conform to the sides of the nut and to be bent around its corner, and provided With a baekWardly-projeetng lug in engagement with the groove Titnessesz and held therein by the inner face of the nut, l BENJAMIN W. KREDIN, substantially as set forth. E. WV. ECHOLS.
