Description

June 23, 1936. C, SAURER 2,045,253
CUSHIONED CAR RAIL Filed June 4, 1931 i INVENTOR EY M ATTORNEYS Patented June 23, 1936 PATENT OFFICE CUSHIONED CAR RAIL Curt Saurer, Akron, Ohio, assignor to The Firestone Tire & Rubber Company, Akron, Ohio, a
corporation of Ohio Application June 4, 1931, serial No. 541,962
1 Claim.
All car rails are subject to vibration induced by the passage of cars and other vehicles thereover, and when the rails are embedded in concrete or similar material, such vibration quickly effects separation of the rail and concrete and eventually damages the foundation structure of the rails, the destructive action of the vibration being expedited by moisture which enters the 'space between the rails and the concrete after their initial separation. Attempts to remedy the situation, so lfar as I am aware, consist in mounting shock absorbing fibre blocks between rails and ties, and while this expedient protects the foundation structure from rail vibration, it does not prevent the head or flange of the rails from damaging the adjacent concrete, and does not prevent the entrance of moisture.
'Ihe chief objects of this invention are to prevent damage to the foundation structure of a railway from rail vibration; to prevent damage .to adjacent concrete or brick from vibration of the head and/or flange of the-rails; to reduce the noise incidental to car travel on the rails; and to prevent the entrance of moisture between the rails and adjacent pavement.
'I'he single 'figure of the accompanying drawing is a transverse section through one rail of a v railway embodying the invention in its preferred form.
Referring to the drawing, I is track rail, and is shown herein as a rail of the type comprising a head II formed with alateral flange I2, the rail also having the usual base portion I3. Mounted upon the under side of the head II and flange I2 of the rail are respective cushions I4, I4 of resilient rubber composition, said cushions extending longitudinally the full length of the rail. The cushions I4 either are vulcanized to the rail, or are adhesively attached thereto after initially being vulcanized in extruded or molded form. The bottom face of the base portion I3 of the rail is provided with a resilient rubber cushion I5 which may consist of a single strip extending the full length of the rail, or it may consist of a plurality of short strips that are spaced apart so as to underlie only those portions of the rail that rest upon ties, such as the metal (Cl. 23S-9) tie I6. The cushion or cushions I5 are applied to the rail in the same manner as the cushions I4. Suitable bolts I1 are provided for securing the rail I0 to the tie I6, which bolts extend through suitable apertures formed in the tie I6, cushion I5, and rail base I3, and are provided respectively with washers I8 having non-parallel faces, and nuts I9 for urging said washers against the top face of the rail base I3.
The railway consisting of parallel rails of the construction and mounting described, when laid in a paved roadway is substantially embedded in the paving material such as the concrete 20, only the top of the rail head II and ange I2 being exposed. In pouring the concrete, narrow spaces are left along the lateral faces of the said head and ange, and these spaces subsequently are filled vwith a composition of asphalt, pitch or rubber that adheres' to the rail and to the concrete and provides seals 2I, 2| to prevent the entrance of moisture between the rail and pavement.
Preferably the seals 2| are of such composition and consistency as to remain permanently flexible, that is, never to crack or fracture under the rail-vibration to which they are subjected.
When the trackway is initially constructed, the concrete adheres to the rails, but after a relatively short interval of use, due to vibration of the rails, this adhesion fails and a crack is formed between the metal and the concrete. Thereafter vibration of the rails is absorbed by the rubber cushions I4, I5 and further damage to the pavement or rail-supporting structure is obviated. i 35 Modification may be resorted to within the scope of the appended claim which is not limited wholly to the specific construction shown and described.
What is claimed is:
In a railway, the combination of ties, track rails, rubber cushions between theties and track rails, rubber cushions on the under side of the heads of the rails, and rigid paving material in contact with the sides of the rails and with the aforesaid members in which the paving material is flush with the top surface of the rails, including non-frang'ible water seals between the lateral faces of the rail heads and the adjacent pavement structure. 50
