Application September 29, 1949, Serial No. 118,617

4 Claims.

My present invention relates to a railway rail mounting, and particularly to such a structure having means to facilitate the mounting of railway rails upon ties, or other similar bed.

It is well known in railroad construction that the rails, particularly when carrying the moving load of locomotives, cars, trains, or vehicles in general, impart loads, stresses, strains, forces, or deflections upon the plates on which the rails are supported causing rocking and crawling of the plates upon or over the ties, or other similar bed. There is present also a clatter and slap of the tie plates due to the vibration of the rails and due to the impact of the rolling loads which causes pounding of the rails upon the tie plates.

One of the principal objects of this invention is to provide means, in the form of a railway rail mounting, for uniformly applying the transmitted loadon the rails to the rail supporting areas of the ties, or similar bed, by the adjustment or accommodation of rail cushioning material to the irregularities of such supporting areas.

Another important object of this invention is to provide a railway rail mounting having means comprising a tie shield in the form of a relatively flexible, resilient, cushion designed to be placed between the railway tie, or similar bed, and the rail tie plate on which is supported a railway rail, normally subjected to manifold stresses, strains, and forces, and consequent movements, to minimize abrasion and crushing of the tie, or other bed by the tie plate.

An important object also of this invention is to provide a rail mounting of this class having such a tie shield in the form of a resilient cushion for supporting a rail tie plate on a tie, or similar base, in which the tie shield or cushion comprises a relatively flexible, resilient, cushioning material having embedded therein a relatively flexible, resilient, metallic reinforcing member which is positioned immediately adjacent the underside of the tie plate and affords substantially a metal-to-metal contact with and support for the plate, thereby relatively rigidly supporting the plate on the tie shield and yieldably supporting the shield on the tie, or the like, for the purpose specified.

A further important object of this invention 7 is to provide a tie shield comprising a relatively flexible, resilient, and slightly pliable cushioning material in which is embedded a perforate, flexible, and resilient metallic reinforcing member having a multiplicity of spaced cavities, voids,

or dams, in which the normally expansible and and extensible material is confined or restrained and thereby prevented from being laterally displaced when direct or component vertical stress or load is applied on'or to the rail and plate.

With these and other objects in view, as will appear hereinafter, I have devised a railway rail mounting having certain novel features of construction, combination, and arrangement of parts and portions, as will be hereinafter described in detail, and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Fig. 1 is a fragmentary side elevational view of a conventional railroad tie with a rail, shown in section, supported thereon, the mounting of the rail embodying my invention, the section being taken through Il of Fig. 2;

Fig. 2 is a fragmentary plan view thereof, portions being broken away and in section to facilitate the illustration; and

Fig. 3 is an enlarged fragmentary sectional view thereof, taken through 3-3 of Fig. 2, showing particularly the construction of my tie shield, embodying my invention, for supporting a tie plate on a tie.

The illustration shown in the drawings, as embodying my invention, shows a conventional railway rail i supported on a conventional railway tie 2. The term tie, as employedherein, is an inclusive term and applies to other means providing a similar rail support or bed.

In conventional railroad construction, the lower flange I of the rail is supported on a heavy metallic tie plate 3 which rests upon the tie, the base flange l being located between spaced flanges 3 of the tie plate. The flange of the rail is secured with the tie plate to the tie by the conventional railroad spikes 4, the spikes bein shown as extending through holes in the tie plate.

In my railway rail mounting, I provide atie shield 5 which, in thickness, is more or less the same as the tie plate, in width it is approximately that of the tie, and in length as long or longer than the tie plate, thereby affording maximum distribution, to or over the surface of the tie, of the loads transmitted to the tie plate.

The tie shield, as here shown, may be secured to the tie with the same spikes 4 which secure the rail and tie plate in position.

The tie shield provides substantially a (Bushion for the tie plate upon the tie, and the whole thereof is relatively flexible and resilient in, primarily, a vertical direction. It yields readily vertically in accommodating the shield to any unevenness in the upper surface of the tie, and also provides the desired cushioning efiect in a vertical direction due to the varying loads upon the rail.

The shield comprises a body 5 of relatively flexible resilient cushioning material which is slightly pliable. It consists preferably of an asphaltic material, with or without added fibrous material, or other material having similar properties of flexibility, resiliency, or the like. Within the body or the material 5 is embedded a reinforcing 5 which is a relatively flexible, resilient metallic member. This member 5 is shown as being in the form of heavy wire mesh.

Although the tie shield has been described in such a manner that it may be secured to the tie bythe spikes 4, it will be observed that it may be additionally or independently secured to the tie by staples, nails, spikes, or other means (the means not being shown), to prevent its movement with relation to the tie as the tie plate rocks, crawls, chatters, and slaps, on and over the upper surfaces of the metallic member of the shield.

One of the important characteristics of this flexible, resilient metallic member is that it has a multiplicity of spaced interstices, cavities, voids, or dams, which confine and restrain the asphaltic material, or material described, so that it is prevented from being laterally displaced, to any appreciable extent, when a direct or component vertical stress or load is applied on Or to the rail and the plate. When it is so confined or restrained it provides the desired cushioning effect, in a vertical direction, for the plate upon the tie.

The flexible and resilient metallic member or wire mesh 5* is so embedded within the asphaltic material 5*, or other material described, that the upper portion of the metallic member 5 is in juxtaposition or substantially engages the underside of the tie plate, as best shown in Fig. 2, so that there appears between these members a substantial and positive metal-to-metal contact. In this manner, the load is substantially directly imparted to the metallic member 5'.

The asphaltic material 5 or other material described, is'considerably thicker at the under side of the member 5 and for this reason it is more readily forced or impregnated into the wood of the tie and permits the material of the tie shield to conform more readily to any irregularities in the upper surface of the tie.

The tie shield 5 may be made by making the metallic member 5* in the desired shape and then filling the interstices, cavities, voids, or other contiguous portions, of the metallic member 5 and coating it to the desired thickness by dipping, pressing, or rolling into or over it the flexible, resilient cushioning material in Lil such a manner as to secure a filling of the spaced interstices, cavities, voids, or dams, of the metallic member 5 and the underside coating thereof, and a secure bonding between the metallic member 5 and the flexible, resilient cushioning material. This is the preferable method of manufacturing the same if the member 5 is made of Wire mesh or netting.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art. It is also understood that the specific terms employed in the claims include the broad definition applied in the specification.
