To (LZ/' whom t may concern: being confined to that part of it which is Beit known that I, PAUL KNOCH, of Adlersactually in contact with the rail.

Hitherto there have been employed felt lVhile manycoinpoundsinaybe used to prosupporting-plates, impregnated uniformly duce the superficial hardening above referred 6o throughout, and their upper surface on which to, I have found that a Very efficient protecthe rail rests therefore is just as yielding as tion is afforded to the supporting-plate bythe i 5 the remainder of the supporting-plate. Since following described process: The felt having in order to be elastic the felt su pporting-plate first been treated in its entire body to increase niust be soft, the rail is not securely supported its durability throughout, it is coated with a 65 unless an additional iron plate is interposed, layer of glue, which is allowed to penetrate to and Avery often Jche edges of the rails base will a depth of about four millimeters, and this zo cutinto the felt supporting-plate, thereby renlayer is then impregnated with chrome-alum, dering it useless and necessitating the subbichroinate of potash, soda, formalin, or the stitution of a new one.
