COMPLETE SPECIFICATION.
Improvements in Condensing Apparatus for Steam Engines.
We GEORGE ERNEST HUDSON of "The Scarborough Brewery Company,"
Westborough, Brewer and Wine Merchant, and GEORGE SANDERSON of
25 Victoria Road, Mechanical Engineer, both of Scarborough in the County of
York, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
Our invention relates to certain improvements upon and additions to the apparatus
described in our Specification dated the 3rd day of February 1893 Number 2418
for which Letters Patent have been granted to us.
According to our present invention, we remove the oil or grease from the exhaust
steam of a non condensing steam engine, we then condense the purified steam, and
while the water resulting from such condensation is still in a heated state, we
employ it for feeding boilers and other purposes. By means of this condensation
of steam, assisted by an air pump, we form a vacuum in the condenser which adds
greatly to the power exerted by the steam engine to which it is connected.
In order to enable our invention to be fully understood, we will proceed to
describe the same with reference to the accompanying drawing, which represents
a sectional elevation of our condensing apparatus.
Exhaust steam from the engine passes by the pipe A into the chamber B, where
the oil or other lubricants are deposited, principally upon the sides of the chamber,
from whence the deposited grease mixed with the water, passes through the valve
or plug S into the receiving chamber C, from which chamber the grease and
water mingled are drawn off at the cock T, after opening the vent tap at R to
admit air.
The partially purified steam next passes, after leaving the chamber B, along the
pipe D to the condenser E, where a jet of water from the pipe F meets the steam
and further completes the condensation.
The resulting hot water falls to the lower part of the chamber E, from whence
it is drawn off by the pipe G.
The surface condenser J J fully completes the condensation of any steam which
may escape by the pipe H from the condenser E, whereby a vacuum is formed with
the aid of the air pump N.
The receiving chamber C and the condenser E are provided with glass water-
gauges P and O respectively to indicate the levels of the liquids they contain.
The return pipe U conducts the water formed by condensation in the surface
condenser JJ to the condenser E, where it mixes with the hot water already
condensed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In combination with the condensing apparatus such as is represented in the
accompanying drawing, the oil or grease condensing chamber B and the receiving
chamber both operating in the manner and for the purpose set forth.
2. The construction and arrangement of the combined apparatus herein described
consisting of an oil separating chamber, and an oil or grease and water receiving
chamber, a jet condenser and receiver for hot water with feed pipes affixed thereto,

page_text: connected to an ordinary condenser and air pump for producing a vacuum, all
operating in the manner and for the purpose.herein described.
Dated this Eighth day of September 1893.
