NUT-LOCK.

' SPECIFICATION formingpart of Letters Patent No.727,314, dated May 5, 1903. Application filed June 17, um. Serial No. 112,073. we model.)

To all whom it may concern:

Be it known that I, JOHN A. DUFFY, a citizen of the United States, residing at Pomona, county of Los Angeles, and State of California, have invented new and useful Improvements in Nut-Locks, of which the following is a specification.

My invention relates to new and useful improvements in nut-locks adapted to be used in connection with nuts on railways, wagons,

cars, bridges, &c.; and its object is to provide a combined washer and lock which is cheap and durable and can be readily removed or replaced without the services of an expert.

l/Vith the above and other objects in view the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure 1 is a perspective View showing the nut-lock in position upon a'rail. Fig. 2 is a view of a blank from which the lock is formed. Fig. 3 is a detail view of a modified form of lock. Fig. 4 is a view of the blank from which it is formed. Fig. 5 is a perspective view of a second modified form of lock. Fig. 6 is a further modification. Fig. 7 is a perspective view showing another form of lock in position upon a raiL, Fig. 8 is a plan view of the blank of said modification. Fig. 9 is a detail View of a strengthening-bar for said lock. Fig. 10 is a perspective view of the lock shown in Fig. 1, the same being provided with means for securing at a point removed from the nut; and Fig. 11 is a plan view of the blank from which said lock is formed.

Referring to the figures by numerals of reference, 1 is a washer having an aperture 2 therein for the reception of a bolt 3. One end of the washer is bent upon itself to form a locking portion 1, and the edge 5 thereof is turned inward and serves to hold the portion 4 spaced from the washer. The edge 5 and the lock etare provided at the center with a recess 6 for the reception of the nut 7 of the bolt. Arms 8 are formed at opposite sides of the washer and are adapted to be bent over the lock L and hold it in proper relation to the washer.

In use the washer is placed on the bolt and isclamped against the fish-plate by the nut 7. The tread and base of the rail prevent the washer from turning. To lock the nut, the portion 4 is swung into position at opposite sides thereof and held there by the arms 8, which are turned thereover.

If desired, the arms 8 may be dispensed with, as shown in Fig. 3, and in such case the blank would be stamped in the form shown in Fig. 1 from a single sheet of metal. Also, if desired, the arms 8 can be located at the center of the blank and both ends of said blank made similar. If constructed in this manner,the two ends would be pressed against the opposite sides of the nut and the recesses 6 receive the same.- The-arms 8 would extend over the adjacent edges of the ends and hold them securely against outward movement. It is not necessary, however, to employ these arms with this construction, for the ends of the blank can be recurved, as shown at 9, and placed into engagement with each other.

In Fig. 7 I have shown a form of lock in which a strengthening-bar 10 is employed in addition to the look before described. This bar is preferably formed of cast metal, and the central portion 11 is reduced to receive the nut '7. An aperture 12 is formed in the reduced portion to receive the bolt 3, and an angular head 13 is arranged at each end of the bar. The end 5 of the lock is adapted to extend over these heads 13 and are held in position thereon by the arms lal. These arms are similar to the arms 8, but are located at one end of the blank instead of at points be tween the ends. The bar 10 prevents the look at from being mashed or otherwise injured by blows thereon.

On bridges or at other places where it is desirable or necessary to secure the washers at points removed from the nuts an arm 15 may be provided, the same being merely a continuation of the fiat end of the washer 1.-

This arm, if desired, may be provided with oppositely-extending hooked securing-arms 16, adapted to engagea strip of metal or other material, and a screw 17 may, if desired, also be employed to secure the arm 15 to said strip.

In the foregoing description I have shown the preferred forms of my invention; but I do not limit myself thereto, as I am aware that modifications maybe made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and modifications as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim as new is- 1. The combination with a washer, of an extended portion bent upon the washer to provide a locking member, the edge of the said portion being turned inwardly and engaging the washer, to hold said member spaced apart from the washer, and means to hold the edge of said portion in engagement with the washer.

2. The combination with a washer; of an eX- tended portion bent upon the washer to provide a locking member, a bolt-receiving bar interposed between said member and the washer, and an arm to the washer adapted to engage the member and retain it upon the bar.

3. The combination with a washer, of an extended portion bent upon the Washer to provide a locking member, the edge of said portion being bent inwardly and engaging the washer to hold the said member spaced apart from the washer, and an arm integral with the washer and engaging the locking member to hold it in position.

4. The combination with a washer, of a nut-engaging portion bent upon the washer to provide a locking member, means for spacing the locking member apart from the washer, and an arm formed integral with the washer and adapted to be bent over the lock ing member to hold it and the spacing means in position.

5. The combination with a washer, of oppositely-arranged recessed portions bent toward each other to form a locking member, substantially parallel to the washer, the recesses registering to form a nut-receiving aperture, and means integral with said members to space them apart from the washer.

6. The combination with a washer, of oppositely-arranged recessed portions bent toward each other to form a locking member, the recesses registering to form a nut-receiving aperture, the edges of the recessed portions being turned inwardly and engaging the washer to space the locking member away from the washer, and oppositely-arranged laterally -projecting arms integral with the washer and adapted to be bent over the locking member to hold it in position.

7. The combination with a washer, of an extended portion bent upon the washer to provide a locking member, means integral with the member to hold it spaced apart from the washer, and means integral with the Washer to hold the locking member in position.

8. The combination with a washer, of an extended portion bent upon the washer to provide a locking member, means to hold the member spaced apart from the washer, and means integral with the washer to hold the locking member in position.

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

JOHN A. DUFFY.
