1862 London Exhibition: Catalogue: Class V.: Thomas S. Truss
1305. TRUSS, THOMAS S., C.E., 53 Gracechurch Street, London.
Patent cushioned railway chair, and packing.
T. S. TRUSS, C.E., 53 Gracechurch Street, London, is the patentee and manufacturer of chemically prepared woollen packing for pipe joints, tanks, bed-plates, railway chairs, etc., etc.
By the application of this packing to railway chairs, the chair and the under head of the rail are entirely protected from friction.
The working head will last much longer, as the violent concussion caused by the train is absorbed by the packing, and thus the nature of the metal is preserved. This packing is made of any required size, form, or thickness, and is rendered almost indestructible by the process through which it is passed.
Reference to the sectional drawing of railway chair: A, chair; B, rail; C, patent packing; D, wood key; E, wood seating.
