Improvements in the Method and Means for Discharging the Vapour
Generated in the Water Jackets of Gas and Oil Engines.
WALTER ARNOLD of East Peckham in the County of Kent Engineer do hereby
declare the nature of my said invention to be as follows:-
The object of my invention is to construct a new form of Condenser, for con-
densing the vapour arising from the Water contained in the Water jacket of Gas,
or Oil Engines; my invention being more especially, but not exclusively, applic-
able to engines for motor carriages.
According to my invention, I construct a chamber or vessel, which may be
cylindrical, rectangular, elliptical, polygonal, globular, or of any other suitable
form, provision being made by means of bars, plates, or other suitable appliances
for securing the same in position and rendering it capable of retaining its shape.
The wall or walls of the chamber is or are formed of wire gauze or other perforated
material; having minute holes or interstices through the same.
The exhaust from the water jacket of the Gas or Oil Engine is laid on to this
Condenser in any convenient manner.
The exhaust steam entering the chamber at a low pressure escapes through the
interstices or perforations, and is thereby sub-divided into a great number of
very small jets, which mix with the external air and thereby become speedily
condensed and absorbed by the atmosphere, the area of surface-contact of steam
and air being very great, in consequence of the minuteness of the issuing jets of
steam.

Improvements in the Method and Means for Discharging the Vapour
Generated in the Water Jackets of Gas and Oil Engines.
I, WALTER ARNOLD, of East Peckham, in the County of Kent, Engineer, do
hereby declare the nature of my said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of my invention is to construct a new form of condenser, for con-
densing the vapour arising from the water contained in the water jacket of gas
or oil engines; my invention being more especially, but not exclusively, applicable
to engines for motor carriages.

page_text: According to my invention, I construct a chamber or vessel, which may be
cylindrical, rectangular, elliptical, polygonal, globular, or of any other suitable
form, provision being made by means of bars, plates, or other suitable appliances
for securing the same in position and rendering it capable of retaining its shape.
The wall or walls of the chamber is or are formed of wire gauze or other per-
forated material, having minute holes or interstices through the same.
The exhaust from the water jacket of the gas or oil engine is laid on to the
condenser in any convenient manner.
The exhaust steam entering the chamber at a low pressure escapes through the
interstices or perforations, and is thereby subdivided into a great number of very
small iets, which mix with the internal air and thereby become speedily condensed
and absorbed by the atmosphere, the area of surface-contact of steam and air
being very great, in consequence of the minuteness of the issuing jets of steam.
And in order that my said invention may be particularly described and ascer-
tained reference is hereby made to the accompanying drawings, illustrating one
method of carrying out my invention, in which similar figures of reference
indicate corresponding parts.
Fig. 1 is an end view of a cylindrical condenser, and Fig. 2 is a sectional
elevation.
3, 3, are the cylinder covers, which are retained at a suitable distance apart by
stay tubes 4, 4, 4, secured thereto as shown. 5, 5, are steam inlets through which
the steam or vapour gains access to the condenser. 6 is a wire gauze cover
secured round the stay tubes, as shown by dotted lines in Fig. 1, and partly
in Fig. 2.
The outer gauze covering 7 is secured to the flanges of the cylinder covers by
brass hoops 8, 8, the gauze being stretched from end to end of the cylinder between
the flanges.
The steam or vapour entering the cylinder at one or both ends first passes
through the gazze envelope 6, and secondly through the gauze envelope 7 to the
outer atmosphere, where it becomes thoroughly dissipated and condensed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improved method of condensing the vapour arising from the water
contained in the water jacket of gas or oil engines, substantially as described.
2. In combination with gas and oil engines, the application and use of wire
gauze or equivalent perforated material, whereby the steam or vapour arising
from the water contained in the water jacket is minutely divided and the area of
surface-contact of steam and air is correspondingly increased, substantially as
and for the purpose hereinbefore described and illustrated by the drawings.
