STAY-PLATE FOR RAlLROAD-RAlL. SPIKES.

SPECIFICATION forming part of Letters Patent No. 330,568, dated November 17, 1885.

Application filed June 11, 1885. Serial No. 168,422.

To all whom it may concern:

Be it known that I, THOMAS A. DAVIES, of the city, county, and State of New York, have invented certain new and useful Improve ments in Stay-Plates for Railroad-Rail Spikes, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a portion of arailroad rail and tie and two inclined spikes to which my improved stay-plates have been applied. Fig. 2 is a plan View of a portion of a railroad rail and tie and two upright spikes to which myimproved stay-plates have been applied. Fig. 3 is a sectional elevation of the rail, tie, and stay-plates, the spikes being shown in side elevation. Fig. 4.- is a side elevation of one of the stay-plates. Fig. 5 is an end elevation of the same.

The object of this invention is to provide stay plates for holding railroad rail spikes firmly in place against the rail-flanges to prevent the rails from having any lateral movement.

The invention consists in the combination, with the rails, ties, and spikes, of tapered plates of a width greater than that of the spikes, driven into the ties at the outer sides of the spikes and transversely with the grain of the wood, as will be hereinafter fully described.

A represents a railroadrail, B a tie, and O the spikes that fasten the rail to the tie, and which may be driven into the tie at an inclination, as indicated in Fig. 1', or vertically, as indicated in Fig. 2.

D is a stay-plate, which is made about two inches square, abouta quarter of an inch thick (No model.)

at its rear edge, and is tapered to a sharp edge at its forward edge.

In using the stay-plate D it is driven into the tie B at the outer side of the spike O and 5 against the lateral pressure of the rail A, so

that the rails will beheld from spreading,and will be kept accurately in line.

By this improvement the annoyance and danger heretofore unavoidable, arising from the spikes being forced laterallyinto the wood, crimping the grain of the wood, and allowing the rails to havea lateral movement,is wholly prevented.

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

1. A re-enf'orce for railroad-ties, consisting of a metal plate adapted to be driven into the tie transversely to the grain of the wood, the said plate being in the rear of the spike and of greater width than the same, substantially as described.

2. The combination, with the rails A, the ties B, and the spikes G, of the wedge shaped plates D, driven into the ties at the outer sides of the spikes and transversely to the grain of the wood, the said plates being of a greater width than the spikes, substantially as shown and described, whereby provision is made for metal lining or re-enforcing the fiber of the Wood to prevent lateral crushing of the same, as set forth.
