FELTMATS FOR RAILS.
Noise of Moving Trains Will Be Deadened.
Mention has already been made of the invention of a material for the deadening of the sound produced by moving trains, and was exhibited at Leipsic last summer. The new mat is described as being made of strong wool, which is thoroughly impregnated with oils, then superficially coated with glue, which has been rendered insoluble by the addition of sodium bichromate and formaldehyde, and then very highly compressed to form plates from one-third inch to several inches in thickness and of various sizes. They are especially recommended for crossings and bridges, but are desirable for use all along the track, and it is claimed that they tend to prolong the life of the rail by lessening the wear upon it. The surface of the mat is said to be so hard that a rail may be placed upon such a piece of matting without cutting it. When placed between the girders and foundations of engines it considerably lessens the vibration. Its use in connection with the elevated roads in large cities has also been suggested.

Invention of a material made of strong wool impregnated with oils, coated with insoluble glue, and compressed into plates to deaden sound of moving trains, exhibited at Leipsic last summer. Recommended for crossings, bridges, and tracks to reduce noise and wear on rails; hard surface withstands rail weight; lessens vibration under engines; suggested for elevated roads in large cities.
