SPECIFICATION forming part of Letters Patent No. l758,463, dated April 26, 1904.

Application ned Obaba 10, 1903A.v

` T a/ZZ whom it may concern:

Be it known that we, WILLIAM A. NICHOLS and JOHN F. NEFF, citizens of theUnited States, and residents of Belmont, in the county of Belmont and State of Ohio, have invented a new and useful Improvement in Railway-Ties, of which the following is a specification.

Our invention relates to an improvement in railway-ties, and is composed of wood and metal so proportioned and arranged that a relatively small amount of wood is required, and the wooden portion is surrounded by the metal except on the lower surface, where it rests on the road-bed with the metal portion of the tie; and it consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a view of a section of a railroad-bed in plan, showing the application of our improvements. Fig. 2 is a longitudinal sectional view through one of our improved ties; and Figs. 3 and l are transverse sections, one through the central portion of the tie and one through one of the grooves.

The tie comprises a metal portion which may be cast in the form of a box or inverted trough, comprising the vtop 1, sides 2 2, and ends 3 3, it being hollow through the center and open along the bottom. The hollow center is provided with a filling 4, relatively small in dimensions as compared with the surrounding metal and the lower surface of which is flush, preferably, with the remaining portion of the tie where it rests upon the road-bed, the object of this arrangement being to insure the support of the wooden portion upon the ground, so that it will have the accustomed cushioning eifect of an ordinary wooden tie, while possessing the advantages of an allmetal tie by virtue of' the surrounding case of metal.

I The tie is transversely grooved, asat 5 5, and these grooves just extend to the surface of the wood. The wooden vblocks 6 6 are fitted in these grooves and may or may not be secured to the wooden iilling upon which they rest throughout their centers, while being supported at or near their ends upon the Serial No. 176,507 (No model.)

metal sides 2 2 of the tie. VLikewise these blocks may, if desired, be of sufficient length to rest at their ends upon the ballast. Likewise it is our purpose to thicken the metal more or less, as at 7 7, where these blocks rest, in order to give the required strength where the pressure of the rails and rollingstock is largely sustained. The upper surfaces of the blocks 6 6 are preferably lower than the upper surface of the tie, so that grooves are still formed for the rails 8 8. A notch 10 is formed in the sides of the metal groove to receive the vertical flange of the L- shaped clamping-bolt 9; also,a notch for spike, if such is used, between the edge of the rail and the edge of the groove, whereby a ri'gid fastening is provided for the rails. These clamping bolts or spikes may extend in opposite directions on opposite sides of the rails after the usual manner of driving the spikes in railroad construction. In this way both the rails and blocks are clamped or spiked on each side, and thus prevented from appreciable movement or vibration, thus producing a solid road-bed. In this-way we are enabled to greatly reduce the amount of wood used, while at the same time deriving the necessary elasticity in -the tie and preventing the contact of rails and metal portions of the tie, thus eliminating the noise and clatter which would otherwise result.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of our invention, and hence we do not wish to limit ourselves to the exact construction herein set forth; but,

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is- I l. Arailway-tie, comprisingabox or inverted-trough shaped metal portion, and awooden portion inclosed thereby at its sides, top and ends, with its lower surface resting upon and supported solely upon the ground, the tie thus formed being transversely grooved at points where the rails aresupported.

2. 'A railway-tie, comprising a wooden core surrounded on its sides, top and ends with metal, the tie thus formed transversely IOO grooved, wooden blocks located in said grooves, the blocks adapted to receive the rails thereon, and means extending between the blocks and edges of the grooves for clamping the blocks and rails.

3. A railway-tie comprising a wooden core surrounded on all sides but the bottom with metal, the wood and metal flush or approximately ush on the lower surface so that both wood and metal are supported on the roadbed, the tie having transverse grooves on its upper surface, the sides of the metal portion being thickened at the ends of the grooves, Wooden blocks of less Width than the Width of the grooves, located in said grooves, and

fastening means for clamping the blocks and rails to the tie thus formed.

4. A railway-tie comprising an outer shell of metal entirely open at the bottom and a wooden core which fills the outer shell adapted to rest at the bottom upon the road-bed and adapted to sustain the rails thereon.

In testimony whereof We have signed this specification in the presence of two subscribing Witnesses.
