ROLLED STEEI; WELDED PAVING CHUCK Filed 1951 INVENTOR BY '8 ATTORNEYS 124.4% M
Patented July 12, 1932 UNITED STATES PATENT OFFICE ROLLED STEEL WELDED PAVING- CHOCK Application filed August 26, 1931. Serial No. 559,563.
This invention relates to paving chocks for railway track structures. Heretofore paving chocks have been comprised of cast materials and consequently must be specially cast to fit in any specific track structure Such cast paving chocks are heavy, cumbersome and not particularly strong.
One of the objects of this invention is to provide a relatively light, strong and durable paving chock for railway track structures.
Another object is to provide a paving chock comprised of material that can be adapted or shaped to special sizes and dimensions.
Another object is to facilitate the assembly of railway track structures.
Other objects and advantages will become apparent as the invention is more fully disclosed.
In accordance with the objects of the present invention I have devised a novel type of paving chock comprised of rolled steel material, including a plate member, which may be shaped or cut to fit in any desired position in the railway structure, and supported therein by associated rolled steel bracing or supporting members welded thereto. The rolled sheet steel plate is preferably provided upon one face with a series of corrugations or raised portions adapted to provide traction facilities.
Before further disclosing the present invention reference should be made to the accompanying drawing, wherein- Fig. 1 is a plan view of the top of a railway track structure incorporating the paving chock of the present invention;
Fig. 2 is a side elevational view of the paving chock structure of the present invention.
Fig. 8 is a section view taken along plane 33, Fig. 1.
Fig. 4 is a sectional view taken along plane H, Fig. 2.
Referring to Fig. 1, the railway track structure shown comprises a switch rail base including converging rails 1 and 2 supported upon a railway road bed in the customary manner, and a paving chock 3 disposed between the rails in such manner as to bring the surface level of the track structure to that of the rail face.
Paving chock 3 is comprised of a sheet metal plate (identified by numeral 3) rolled to the desired thickness and provided upon one (upper) surface with a series of corrugations or offset portions 4, as indicated for the purpose of giving traction to persons or articles traversing the same.
Support or bracing means to retain the plate 3 in position in the railway track structure are provided comprising similar rolled sheet metal parts or sections 5 and 6 adapted to bridge the gap between the rails in the manner indicated and to be supported by the rail base 7 If necessary a longitudinal beam 8 may also be provided for support purposes. The entire assembly of support and plate members is welded together to form a unitary structure as indicated at 9 which may be readily placed in position in the railroad track structure. The welded paving chock 7 assembly is of suflicient weight and mass in larger sizes to be retained in position without the provision of locking means. In small units means to restrain the chock from lateral displacement may be employed.
It is apparent that many modifications of the specific embodiment disclosed herein may be made without departing essentially from the nature and scope of the present invention as may be set forth in the following claims.
lVhat I claim is 1. In railway track structures a paving chock comprised of rolled sheet materials welded together to form a unitary structure.
2. In railway track structures a paving s5 chock comprised of a rolled sheet metal plate, brace and support members therefor, welded together to form a unitary structure.
8. A railway paving chock assembly comprised of a rolled sheet metal plate member,
brace and support members therefor, adapted to engage and to be supported by a railway track structure, said plate and supporting members being welded together to form a unitary structure.
4. A railway paving chock assembly comprised of a rolled sheet metal plate member having one face thereof corrugated to give a traction surface, brace and supporting members therefor adapted to be supported by the elements of a railway track structure, said plate and supporting members being welded together to form a unitary structure.
In witness whereof I have hereunto signed my name.
