FRED .I. HOYT, OF CHICAGO, ILLINOIS.

RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 423,929, dated March 25, 1890. Application filed July 13, 1889. Serial No. 317,425. (No model.)

To all whom it may concern.-

Be it known that I, FRED J. HOYT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railroad-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will 7 enable others skilled in the art to which it [o appertains to make and use the same.

My invention relates to railroad-ties; and it consists of a novel combination of wood and metal, having the combined advantages of a wooden and metallic tie, as hereinafter I 5 described and claimed. It is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a sheet of metal from which the metallic body and ends of the tie are made; Fig. 2, a plan of the complete 2o tie, and Fig. 3 a side elevation of the same.

Referring to the drawings, A represents a sheet of rolled metal, preferably steel, forming a blank for the center and ends of the tie. In practice I make this piece from three- 2 5 eighths to five-eighths of an inch thick,the center about eightinches wide, and the ends about twenty inches wide. The ends are turned up to form boxes B B, with their sides about six inches deep. The central port-ion C is arched,

as shown, the highest portion of the center being on a line with the top of the boxes.

D D are pieces of wooden ties-say about thirty inches long-each set into a boX and firmly secured thereto against shrinkage, &c.,

by bolts 6;

F F are rails spiked to said wooden pieces at the proper gage and in the usual manner.

By my invention a metal tie in all its parts except those parts to which the rails are spiked is had, and all the benefits derived 40 from wooden ties are at the same time produced. The arch gives to the tie great strength and provides against accidents and misplacements due to side thrusts on the rails; also, by my invention the amount of timber usually employed to equip a road with ties is reduced about three-fourths, thus making a great saving in cost of equipment where timber is scarce. The elasticity of a wooden support for the rails, which make the use of such ties so desirable, is retained, while at the same time the durability, strength, and other advantages of a metal tie are procured.

Having thus described my invention, what I claim is- 1. The arched metal tie herein described, provided with boxes turned up on the ends of said tie, in combination with the wooden blocks secured within said boxes to form supports for the rails, substantially as set forth. 6o

2. The metal tie-blank A, provided with a central arched portion C and flaring ends B, substantially as and for the purpose described.

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