UNTTED STATES ATENT FFICEQ RAILROAD-CHAIR.

SPECIFICATION forming part of Letters Patent No. 236,354, dated January 4, 1881.

Application filed August 21, 1880.

To all whom 2t may concern Be itknown that I, MICHAEL It. PERKINS, a citizen of the United States, residing at Portsmouth, in the county of Rockingham and State of New Hampshire, have invented certain new and useful Improvements in Railroad- (Jhairs; and I do hereby declare the following to be ai'ull, 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, reference beinghad t0 the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a perspective view, showing my invention in use; Fig. 2, a side elevation; and Fig. 3 is a perspective view of the two parts forming my invention.

The object of my improvement is to prevent the rails from wearing and settling down into the cross-tie; and it consists ofa flanged metal plate covering and partly inclosing a plate of wood, papier-mach, vulcanized fiber, or other suitable material, which rests upon the crosstie.

A represents a metal plate with openings for spikes, and B B are flanges of any required length, extending down the sides.

0 represents a plate of wood, or other suitable material, such as papier-mach or vulcanized tiber, made to tit snugly between the flanges B B and extend below the edges of the flange a suitable distance, which I will assume to be about one-fourth of its thickness. This plate is provided will openings corresponding with those in the metal plate A, to receive the spikes.

(No model.)

This device may be used only at the ends of the rails, or it may be used over all the crossties.

In using my invention, the plate 0 is held in the plate A upon the cross-tie, with its length parallel to the length of the cross-tie. The rail is then laid upon plate A, and spikes driven through the openings, which are so located as to allow the width of the foot of the rail between them.

This chair does away with the wear and destruction of the cross-tie incident to the use of iron directly in contact with the tie, as in.

the use of iron chairs or of rails placed di' rectly upon the tie.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A chair for railroad-rails, consisting of a metal plate covering and partially inclosing a plate of wood or other suitable material intervening between the metal and the cross-tie, substantially as shown and described.

2. A chair for railroad-rails,consisting of a metal plate provided with a wooden plate intervening between the metal and the crosstie, substantially as shown and described.

3. The combination of plate A. flanges B B, plate 0, and spike and cross-tie, substantially as shown and described.

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

MICHAEL It. PERKINS.
