RAILWAY-TIE.

Specication of Letters Patent.

Application filed January 31, 1911.

Patented Sept. 19, 1911.

Serial No. 605,728.

a citizen of the United States, residing at Provo, in the county of Utah and State of -Utah, have invented certain new and useful Improvements in Railway-Ties; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to railway ties, the objects being to provide a railway tie having a metal body structure with means whereby the rails may be supported at spaced intervals in the length of the rails without the necessity of employing cross connections at every support.

A further object of the invention is to provide a structure in which a plurality of supporting surfaces for each rail will be connected together and united to a corresponding plurality of supports for the opposite rail by a single cross connection whereby the necessity of employing a full cross tie for each pair of supports is avoided.

In the accompanying drawing there is illustrated, in perspective, a railway tie embodying the present improvements, one of the rails being shown in dotted lines.

In said drawing the letter A indicates a trough-like metal cross connection or tie body, preferably formed of sheet or plate metal with a flat bottom portion cl. and vertical side walls a. It is adapted at each end to form chambers for the reception of blocks B of wood or similar material, while transverse extensions C on each end support or form corresponding chambers for the reception of other blocks of wood or similar material B spaced away from the blocks B a distance corresponding approximately to the distance' ordinarily maintained between the usual cross ties.

The body A of the tie and the transverse extensions C at each end thereof may all be formed of plate metal leentI into the proper shape and united by rivets, welding or otherwise, as found most convenient, and the chambers for the reception of the blocks of wood may be similarly formed up of plate metal, the whole being united in a substantially rigid structure adapted to form a very solid support for the rails, present a large flat area for Contact with the road bed, and at the same time afford every facility for tamping, in order to aline the rails in the usual manner.

As illustrated in the drawings, the side walls of the trough-like body A also constitute the side walls of the chambers for the blocks B, and the upper edges of said side walls are bent .inwardly at D to form flan es overlying the blocks. Said flanges and side walls are cut away at (Z to form transverse openings in the tops of the chambers in which the bases of the rails may seat on the supporting blocks B, said flanges and side walls also forming shoulders between which the rails will be held against lateral movement.

For closing the ends of the chambers for the blocks B as well as the chambers for the blocks B', angle plates E, E may be einployed, the plates E being rigidly mounted in position at the inner ends of the chambers, while the plates E at the outei' ends of the chamber are removable so as to permit of the ready insertion and removal of the blocks, but held in place by tongues c passing down through openings in the bottom of the chamber, and by a spike or similar fastening inserted through an opening e in the overlying portion of the said angle plate.

Obviously, the chambers may be formed in various ways; for instance, as illustrated at. G, the inner ends and top portions of the chambers are integral with the side walls being bent down into position to close the ends of the chambers and completely inclose and protect the blocks.

The transverse extensions C aie conveniently of trough-like construction, that is to say, they are open at the top and have vertical side Walls and a flat bottom, suitable provision being made in the form of openings c for the escape of water. The height of the side walls of the troughlike body A and the extensions C will of course depend upon the strength for which the structure is designed and the weight of the metal employed, but it is preferred that they shall approximate in depth or height the thickness of an ordinary railway tie, and while they are primarily designed for use in a manner in which ordinary ties areV employed, said trough-like structures may be readily filled with broken stone or other heavy material which will increase the stability and weight By making the tie with a single cross.

connection between the rails for holding a plurality of rail supports under each rail, it is obvious that the metal employed may be greatly economized.

A tie such as illustrated and described may be used in alternation with ties having single rail supports or they may be used exclusively leaving the usual space between the ends of the transverse projections on adjacent ties. A track laid in accordance with this idea will therefore present three rail supports on each side connected rigidly together and to the corresponding rail' supports on the other side, then a space, and another series of rail supports connected in the manner before described.

For securing the rails in place, ordinary spikes may be employed, and when the blocks have become worn or the spikes loose, said blocks may be withdrawn from their chambers and reversed, thus presenting` new surfaces for the rails to rest upon and new positions for the spikes.

It will be understood, of course, that the chambers at the ends of the transverse projections on the tie have openings through their upper portions in which the bases or flanges of the rails may seat on the wooden blocks, and in the preferred construction the side walls are cut do-wn in alinement wit-h said openings to a point which will prevent the rails from bearing on said side walls.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

l. A, metal tie for railways embodying a cross piece having rail supports at its opposite ends and a transverse extension on each end, each extension having a rail support spaced away from the rail support at the ends of the cross piece.

2. A metal tie for railways embodying a transverse body portion having rail supports at its opposite ends and oppositely disposed extensions at each end, each extension being provided with a rail support spaced from the first mentioned rail support, and the whole constituting a substantially rigid structure, substantially as described.

3. A railway t-ie embodying a metal cross body having chambers in its opposite ends, transverse extensions secured to each end of said cross body and having chambers spaced from the chambers at the ends of the cross body, and blocks of wood or similar material held in said chambers and constituting rail supports.

4. A railway tie embodying a metal body having chambers at its opposite ends, transverse sections on the ends of said tie each having a chamber spaced from the first mentioned chamber, rail supporting securing said blocks in position, whereby a plurality of spaced rail supports are provided at each end of the tie.

5. A railway tie embodying two parallel series of spaced rail supports, the supports of each series being connected together longitudinally of the rail, and a single central connection between the two series of supports.

6. A railway tie embodying a trough-like metal body having chambers in its opposite ends, transverse extensions on opposite sides at each end of said body, each of said extensions having a chamber at its end, all of said chambers having openings therethrough at the top for the admission of rail bases, and blocks held in said chambers for supporting the rails.

7. A railway tie embodying a central metal body extending transversely of the rails and having rail supports at its opposite ends, trough-like extensions arranged at right angles to each end of said body and each having a rail sup-port spaced from the first mentioned rail support.

8. A railway tie embodying a metal body having upturned side walls forming a trough-like structure, and chambers at the ends of said trough-like body, trough-like transverse extensions at each side of vsaid chamber, chambers carried by said trough like extensions, and blocks forming supports for the rails mounted in said chambers.
