- JOIN W. POST, OF NEW YORK, N. Y. IMPROVEMENT IN ELEVATED RALWAYS. Specification forming part of Letters Patent No. 206, 3S-5, lated July 23, 1S7s; application filed July 11, 1878. To all chon it may concern: foundlation-plate of suitable size, which is Be it known that I, JoHN W. POST, of New firmly laid on bed-rock or other substantial York city, in the county of New York and base in a suitable excavation, and securely State of New York, have invented certain new embedded in proper position by cement or oth and useful Improvements in Elevated Rail erwise.

The excavation is then cheap in construction, neat in design, and filled with a packing of any kind, and a suit possessing great strength and durability, and able cap-plate or wheel-guard may be put on which Will not be liable to get out of order, above the surface of the ground, the non and which will in the greatest possible degree vibrating packing between the plate and col obviate the noisy reverberations common to umn serving to materially lessen the vibration other structures for the purpose. of the same, and consequent reverberations, In Order that others skilled in the art to when a train is passing over the SuperStruc which my invention pertains may readily un ture. derstand the same, I will now proceed to de To still further prevent noisy reverbera scribe my invention, reference being had to tions, the columns, which are in all cases made the accompanying drawings and the letters of hollow, may be packed wholly or in part with reference marked thereon. fragments of cork.
