PROVISIONAL SPECIFICATION..
Improvements in Vacuum and other Air Brakes for Railway
Vehicles.
We, MARTIN HENRY GERRING, Engineer, and GEORGE JOHN DYKE,
Auctioneer, both of Coxwell House, Faringdon, in the County of Berks, do
hereby declare the nature of this invention to be as follows:-
The object of the invention is to prevent the "sweating" of the interior of
the cylinder shell or bush and other parts and the consequent freezing of the
ndia-rubber or other ring, band or packing, which renders the brake useless in
frosty weather; it is also a protection against rust and dirt to the working parts,
and results in a saving in the cost of repairs.
The invention consists in coating the interior working parts above referred to
with enamel similar to that now used for lining iron ware, or with other suitable
waterproof material; or the said parts may be lined with vulcanite, which may be
"cured" in position, or a separate lining of vulcanite, glass or other suitable
waterproof material may be fitted within such parts; as an alternative the water-
proof material may be applied to the exterior of the parts referred to, but we
prefer the method herein first described.
By the aid of our invention the parts above referred to are rendered non-porous,
thereby preventing the india-rubber or other ring, band or packing from adhering
to the metal surface or from being injured by contact therewith.
