Improved Apparatus for Separating Oil and other Lubricants from
the Exhaust Steam of Condensing 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 a modification of, combined with certain improvements
in, a portion of the apparatus described in our Provisional Specification dated the
3rd day of February 1893, and numbered 2418, and more fully described in our
Complete Specification filed on the 15th day of May 1893, whereby such portion of
the apparatus is rendered applicable to condensing steam engines, for the purpose
of separating oil and other lubricants from the exhaust steam, before it enters the
condenser, and thereby rendering the water obtained by subsequent condensation
serviceable for many purposes for which greasy water would be useless or
objectionable.
In order to enable our present 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 modified and improved apparatus.
Our improved apparatus is interposed between the cylinder or valve-chest of a
condensing engine and the condenser thereof.
The exhaust steam after leaving the cylinder and valve-chest passes by the
pipe A to the chamber C, upon the inner surface of which chamber the oil and
other grease contained in or carried over mechanically by the rush of steam, is
intercepted and deposited. The baffle-plate D prevents the steam from passing in
a direct line from the inlet pipe A to the outlet pipe B, and causes the steam to he
more thoroughly distributed over the inner surface of the chamber C.
The oil or grease, contained in or carried over by the steam, collects upon the
sides of the chamber C and settles to the lower part thereof, mixed with water,
from whence it passes through the valve E into the receiving tank F.
The hollow float J. suspended by the wire K which passes through the
glands L L is balanced by the weight N attached to a cord passing over the
pulley M. A pointer U indicates upon the scale O the height of the oil and water
in the tank F.
When the receiving tank F requires emptying, which is effected by preference
when the engine is stopped, the cock H at the bottom of the receiving tank is
opened the vent-pipe R is also opened to admit air and the valve E is opened.
The mixture of oil and water will then run freely from the cock H, and after
settling, the oil or other grease may be skimmed from it and further utilized.
The line P P represents the engine-room floor or footplate. The hand-wheel S
is employed to operate the valve E, and the lever V opens or closes the drawing-off
cock H.
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. A vessel such as that represented in the accompanying drawing, and applied
in the manner described, for the purpose of separating oil and other grease from
the exhaust steam of condensing steam engines.
2. An oil or grease-separating vessel, such as is herein described and represented,

page_text: combined with the receiving tank and inlet pipe from the cylinder or valve-chest
of a steam engine, such separating vessel operating upon the. exhaust steam on
its passage to the condenser, also the outlet pipe, valves, vent pipe, float, and
indicator all constructed, arranged and operating in the manner described, and as
represented in the accompanying drawing.
Dated this Fourteenth day of July 1893.
