RAILROAD-TIE.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed February 24, 1905. Serial No. 247,167.

To all whom it nuty concern:

Be it known that 1, PETER G. VAN TON- GEREN, a citizen of the United States, residing at St. Anne, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Railroad- Ties,'0f which the following is a specification.

My invention relates to railway-ties, and has for its object to provide a tie which is practically indestructible through usage or climatic conditions.

A further object of my invention is to provide a railway-tie having independent concrete blocks disposed to carry opposite rails and connected by a flexible plate disposed in a horizontal plane.

A further object of my invention is to pro vide a railway-tie having concrete blocks disposed to carry opposite rails and each block provided with improved strengthening means.

It has been found that ties constructed from non-elastic material, such as concrete, do not offer a sufficiently elastic tread, and it is an object of my invention to provide a concrete tie having an elastic body disposed between the tie and the rail.

A further object of my invention is to provide a tie comprising a concrete block at each end disposed to carry opposite rails and connected by a plate of flexible material and an improved means carried by the plate to secure the rails thereupon.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be here inafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a view of my mproved railway-tie, one end shown in side ation, the other end in vertical section.

7 is a top plan view of my improved railie. Fig. 3 is a transverse sectional of my improved railway-tie, taken on s 3 3 of Figs. 1 and 2.

Like characters of reference designate co rsponding parts throughout the several iews.

In its preferred embodiment my improved railway-tie comprises two concrete blocks 1, disposed. each beneath and perpendicular to a rail 2-. The concrete blocks 1. are formed with a centrally-disposed downwardly-extending angle 3 intermediate the ends and are strengthened by a rigid beam 4 of any approved form embedded therein and extending longitudinally thereof, but stoppin short of the ends thereof. Beneath the block 1 and extending longitudinally thereof is dis posed a strengthening-strip 5, proportioned to conform to the angular formation of the block 1 and secured thereon by any approved means, as the bolt 6, extending through the plate 5 and the block 1.

Upon the top of the block 1 is disposed a plate 7, of any approved elastic material, preferably a block of wood, with the bolts 6 extending through the said block 7. A plate of material 8, preferably of sheet metal, is secured at its opposite ends to and connects the blocks 1, with the bolt 6 continued u nvardly through the plate 8. The plate 8 is provided with openings conveniently disposed to receive bolts S), which are passed theretluough from the under side and extend upwardly. Upon the bolts 9 are disposed clips 10 and nuts 1] to clamp the rail 2 firmly beneath the clips 1.0 and upon the plate 8, which serves as a bearing-surface for the rail. Nuts 12 are disposed upon bolts 6 and serve to clamp firmly together the block 1, strip 5, elastic material 7, and plate 8. As a further protection against a lateral displacement of the rail 2 braces 13 may be disposed upon the bolts 6 between the nuts 12 and the plate 8, with their ends bearing against the web of the rail and beneath the tread. To prevent the dis placement of the elastic material 7, nails or bolts, as H, may be d rivcn through properlydisposed openings in the plate 8 and into the block 7.

The o ')eration of my improved railway-tie is as follows: The two blocks 1 are embedded in the road-bed and the rail 2 laid thereon in the usual manner and secured thereto by the clips 10 and the braces 13. From the construction it will be readily seen that either block may move indepemlently of the other in a vertical plane, but the plate 8 will resista movement in a horizontal plane.

It is well known that concrete ties extending the entire length from rail to rail are subeet to a severe breaking strain by the passage thereover of heavy trains. It will also be seen that by reason of the construction of my improved tie the strain which usually acts to fracture a concrete tie is exerted upon a flexible metal plate. It will further be seen that a tie constructed in accordance with my invention presents double the resistance to a lateral strain exerted upon the rails by reason of presenting two ends instead of one to resist an end thrust. It will further be noted that from the construction of my improved tie the metal connectingplate may be disposed entirely above the surface of the roadbed, and thus submitted in a minimum degree to corrosion. Particular stress is laid upon the fact that in my improved tie the body which comes in contact with the roadbed is non-corrosive and that the member which receives the Wear of the rail is of metal with an elastic block of wood or other approved material disposed between the two nonelastic members for the purpose of cushioning the tread.

IVhile I have shown in detail the preferred form of my tie with the preferred form of railfastener for use in connection therewith, it is obvious that the form and proportion of the concrete blocks may be changed and that any other desired or approved form of rail-fastening may be used in connection therewith.

Having thus described my invention, what I claim as novel, and desire to secure by Letters Patent, isa 1. In a railway-tie, two concrete blocks disposed to carry opposite rails, the said blocks having strengthening-strips along their under surfaces, a flexible plate disposed in a horizontal plane upon the upper surfaces and connecting the two blocks and bolts passing through the strengthening-strips and the plate and rigidly clamping the blocks therebetween.

2. In a railway-tie, two concrete blocks disposed to carry opposite rails, strengthening strips along their under surfaces, a flexible plate disposed in a horizontal plane upon the upper surfaces of and connecting the two blocks bolts passing through the strengthening-strips and the plate and rigidly clamping the blocks therebetween and a rigid core embedded within each of the blocks and extending substantially parallel with the connecting-plate.

3. In a railway-tie, two concrete blocks disposed to carry opposite rails and having strengthening-strips along their under surfaces, a sheet of elastic material disposed upon each of the upper surfaces of the blocks, a flexible connecting member secured. at its opposite ends upon the elastic material and bolts passing through the strengthening strips and connecting member and firmly clamping the block and the elastic material.

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