NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 597,324, dated January 11, 1898.

Application filed April 16, 1897.

To all whom, it may concern.-

Be it known that I, JACOB PRYOR PECK, a citizen of the United States, residing at Sharon, in the county of W'eakley and State of Tennessee, 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.

' This invention relates to certain improvem cuts in nut-locks for railroad rail-joints, the object being to provide in a simple and inexpensive manner a nut-lock which may be readily applied to secure the nuts ordinarily used.

A further object of the lock is to provide means whereby the fish-plate, should it become broken, may be retained in its position without danger of displacement to the rails.

The invention comprises certain novel features of construction and arrangement of parts whereby the above and other important advantages are attained, as will behereinafter fully described, and specifically defined in the appended claims.

In the accompanying drawings, Figure 1 represents a perspective view of the ends of two adjacent rails fastened together by the ordinary fish-plate and bolts and showing my improved nut-lock in position thereon. Fig. 2 is an edge view, on an enlarged scale, removed from the rails; and Fig. 3 is a plan view thereof.

Similar reference-numerals indicate corresponding parts in all figures of the drawings.

1 1 represent the meeting ends of two adjacent rails. 2 is a fish-plate, and 3 the nuts used upon the ends of the bolts, which pass through openings in the fish-plates and the web of the rail in the ordinary manner to secure the rail-sections together.

4 indicates my improved nut-lock, shown as a metallic plate corresponding in length to the length of the fishplate, the intermediate portion of which is provided with a lateral projection 5, in which a square opening 6 is formed to receive within it the head of a spike 6, and the ends are formed with an offset 7 to provide shoulders 7, against which the ends of the fish-plate will bear.

The ofisets 7 of the plate 4 are provided Serial No. 632,378. (No model.)

with elongated openings 8,through which and openings formed in the flange of the rail suitable bolts 8 are passed, their lower extremities being slotted to receive the ordinary split pin, by which means the plate 4 is secured firmly to the Web of the rails.

The intermediate portion of the plate 4 is enlarged upon thelunder side, so that in applying my improved nut-lock the inner edge of the plate, which bears upon the face of the fish-plate, may be brought close up against the under side of the nuts 3, so that the rotation thereof to the slightest degree will be absolutely prevented. The ofisets or ends adjacent to the ends of the fish-plate are broadened, so as to permit of the inner edge of the offiset coming close up to the web of the rail,

as clearly shown in the drawings.

The spike 6 is driven into the opening 6 and through the opening in the web of the rail into the sleeper or cross-tie and serves to assist in retaining the plate 4 in its proper relative position therewith; but this opening may not be considered necessary, and may therefore be entirely dispensed with, and the elongated opening 8 in the offset 7 will provide for the ordinary expansion and contrac- I tion of the rail.

Should the intermediate under side of the plate 4 be so large as to prevent the offsets from engaging with the web of the rail, the split pins or other devices used to engage their slotted ends will serve to draw the offsets toward the web of the rail and thus give greater security thereto.

It will thus be seed that my invention provides in an effective and durable manner a nut-lock which may be readily and quickly applied to rail-joints as at present constructed, and by reason of the shoulders located at the ends thereof the fish-plates, should they become broken or otherwise injured, will be prevented from separating with the rar s.

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

1. Aunt-lock, comprisinga plate having an enlarged intermediate portion provided with an opening, shoulders arranged at each end of the plate and adapted to engage the ends dered ends and provided with openings, slotted boltsto engagezsaid' openings, and open receive bolts adapted to pass through said openings and'openings in thefiange-of the rail, and means to retain said bolts in place, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
