RAIL-JOINT NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 617,579, dated January 10, 1899. Application led August 22, 1898. Serial No. 689,240. (No model.)

To all whom it may concern:

Be it known that we, JACOB M. KINSEY and FRANK P. W. YOUNG, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Rail-Joint Nut- Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

Our invention relates to railjoint' nutlocks; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Figure l is a side elevation of the meeting ends of two rails, the same having our invention applied thereto. Fig. 2 is an enlarged vertical sectional view taken approximately on the line 2 2 of Fig. l. Fig. 3 is a view in perspective of theunder side of one end of the plate made use of in carrying out our invention. Fig. 4 is an enlarged vertical sectional view taken approximately on the lines 4 4 of Figs. 1 and 2.

Referring by numerals to the accompanying drawings, l l indicate the rails, which are of the usual construction ,and 2 the iish-plates. One of these fish-plates is of the usual form and construction, and the opposite fish-plate is provided on the top of the laterally-proj ecting ange with a iat horizontal surface 3, and extending longitudinally throughout this surface and-formed in the iiange of the fishplate is a rectangular groove 4. Formed integral with the top surface of one end of the flange having this surface 3 is a `lug 5.

6 indicates a rectangular metallic bar that lies directly upon the flat surface 3, and formed integral with the under side of said bar is a rib 7, which occupies the groove 4. Formed in the under side of` one end of this plate 6 is a recess 8, into which the lug 5 projects when the plate 6 is located upon theVV iiange. After the bolts 9 have been passed through the bolt-holes in the ends of the rails andvthrough the -sh-plates and the nuts 10 are located upon the screw-threaded ends of said bolts the plate 6 is placed in position upon the iiat surface of the iiange and the fish-plate by sliding it in from one end thereof, and as said plate can only be in this position when the nuts are turned so that their at surfaces are parallel with the surface of the plateit will be seen how said plate forms a perfect lock for said nuts and prevents them turning upon the bolts. The plate 6 is prevented from leaving the ange of the fishplate for the reason that the rib or iiange '7 engages in the groove 4, and said plate is pre'- vented from longitudinal movement, owing to the location of the lug 5 within the recess 8.

A rail-joint nut-lock of our improved construction is simple, inexpensive, very efficient, and is readily applied for use.

IrVe claim- A rail-joint nut-lock, constructed with a' JACOB M. KINSEY. FRANK P. W. YOUNG.
