PROVISIONAL SPECIFICATION.
Improvements in Gas Condensers.
I, SAMUEL CUTLER of Providence Iron Works Millwall, London, Engineer,
do hereby declare the nature of this invention to be as follows:
This invention for Improvements in Gas Condensers relates to the construction of
tubular gas condensers where water or other liquid is employed as the cooling
medium and has for its object to provide means for permitting of the free expansion
and contraction of the condensing tubes under the influence of varying temperature
and thereby dispensing with the use of expansion boxes; and to induce the ready
separation of suspended tar and aqueous vapours from the gas by increasing the
condensing surface.
In one arrangement of gas condensing apparatus constructed according to this
invention the tubes, instead of being straight and provided with expansion boxes
in the ordinary manner, are of a curved sinuous, helical, or spiral form with their
ends rigidly jointed to the tube plates. The water, or other liquid employed as the
cooling medium, enters the tubes at their lower extremities from a common
chamber, and, flowing upwards, is discharged into a receiver surmounting the upper
tube plate and whose outlet is at such a level above the tops of the tubes that an
equal pressure is maintained in all the tubes.
In order to increase the coudensing surface, and induce the ready separation of
suspended tar and aqueous vapours from the gas, I place upon the tubes a number of.
radiating plates in either horizontal or inclined positions.
Although I have described my invention herein as applied to condensers of
vertical form, yet, it will be obvious that I may apply the same construction to gas
condensers of any other form.
In a modified arrangement of condenser, the tubes are also rigidly jointed to the
two tube plates, the upper one of which has its periphery flanged or bent over and
immersed in a lute containing water or other liquid to prevent the escape of gas
from the interior.

COMPLETE SPECIFICATION.
Improvements in Gas Condensers.
I, SAMUEL CUTLER, of Providence Iron Works, Millwall, London, Engineer,
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 :-
This invention for Improvements in Gas Condensers relates to the construction of
tubular gas condensers where water or other liquid is employed as the cooling
n.edium, and has for its object to provide means for permitting free expansion and
contraction of the condensing tubes under the influence of varying temperature
thereby dispensing with the use of expansion boxes, also to induce the ready
separation of suspended tar and aqueous vapours from the gas by increasing the
condensing surface.

In the accompanying sheet of illustrative drawings
Fig. 1 represents partly in elevation and partly in vertical section, one form
of condenser constructed according to this invention, and
Fig. 2 represents a vertical section of a part of a modified arrangement of
condenser.
Referring to Fig. 1 the tubes a instead of being straight and provided with
expansion boxes in the ordinary manner are of a curved sinuous, helical, or spiral
form with their ends rigidly jointed to the tube plates bc by nuts d. The water or
other liquid employed as the cooling medium enters the tubes at their lower
extremities from a common chamber e and flowing upwards is discharged into
a receiver f surmounting the upper tube plate c and whose outlet g is at such a level
above the tops of the tubes a that an equal pressure is maintained in all the tubes
as will be readily understood.
In order to increase the condensing surface and induce the ready separation of
suspended tar and aqueous vapours from the gas I place upon the tubes a number
of radiating plates h which may be either in horizontal positions as shown or in
inclined positions.
Although I have described my invention as applied to condensers of vertical
form yet it will be obvious that I may apply the same construction to gas condensers
of any other form.
In the modified arrangement of condenser shown in Fig. the tubes a are also
rigidly jointed to the tube plates, the upper one i of which has a flange which is
immersed in a lute m containing water or other liquid to prevent the escape of gas
from the interior.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In gas condensers, the employment of bent tubes rigidly connected to their
tube plates substantially as described, and for the purpose set forth.
2. In gas condensers the employment of radiating plates mounted on the tubes
for the purpose specified.
3. The arrangement and construction of gas condensers substantially as described
with reference to Fig. 1 of the drawings.
4. The arrangement and construction of gas condensers substantially as described
with reference to Fig. 2 of the drawings.
