I JAMES BROWN EDMISTON of 1 Highfield Road Walton near Liverpool in the
County of Lancaster, Engineer, do hereby declare the nature of the said invention
for "IMPROVEMENTS IN CONDENSERS" to be as follows:-
The invention relates to condensers mainly for use on board ship for condensing
steam, produced by distillation of sea water or from deck boilers or winches and
like sources, and the object is to provide a condenser which shall be economical in
construction occupy comparatively small space and have large and efficient cooling
and condensing surfaces.
The invention consists essentially in the combination of duplex or double walled
cellular compartments contained in a casing or chamber and communicating with
each other centrally and annularly suitable steam and water connections being
provided.
In practice I find the following construction answers well. A cylindrical cast
iron casing or chamber is fitted with covers at each 'end and has openings for the
inflow and outflow of water. The cellular compartments are preferably of sheet
copper, are double walled, annular in shape and superposed one on another within
the case or chamber so as to leave central openings from the case or chamber and
from one to another. The spaces between the double walls communicate annularly
from compartment to compartment and at each extremity by a pipe or pipes with
the steam supply and condensed water outflow.
In use steam from the supply enters the space between the double walls, and
cold water flows through the casing and central cavities of the cellular com-
partments.

formed, to be particularly described and ascertained in and by the following
statement:-

DESCRIPTION OF THE DRAWINGS.
Fig. 1. is an elevation and figs. 2 and 3 plan views at the lines A. A. B. B of a
condenser constructed in accordance with my invention a. is a cylindrical cast
iron chamber carried on a base b. forming a reservoir and the bottom cover. c. top
cover
The covers and chambers are bolted together or otherwise attached as may
be found desirable. d. inflow and e. discharge openings for the condensing water.
Each cellular compartment is formed of double or exterior and interior walls f. g.
preferably of sheet copper brazed together as shown at h. If preferred the walls
may be bolted together. i. are ferules or pieces for keeping the compartment walls
at the required distance apart. The compartments formed by the double walls aro
superposed one on another and connected together by brazed or soldered joints as
shown at j. When fitted together a series of steam compartments k. connected by
annular spaces * are formed. l. steam inlet pipes opening into the top compart-
ment M. condensed water pipes leading from the bottom compartment into the
reservoir forming the base b. N. diaphragm plates secured to carrying bars O. The
said diaphragms or plates fit between the compartments so as to cause the condensing
water to pursue a zig zag path through the chamber a, and come in contact with
every portion of the exterior walls of the condenser compartments. p. pipe leading
from the chamber a. up within the central space formed by the interior walls of
the compartments. The said pipe is closed at the top and has openings q. at
regular intervals so that the condensing water in passing through the pipe will be
projected against every portion of the interior walls of the compartments The
interior and exterior walls of the compartments are connected together at the ends
by the screwed tubes and nuts r. The arrows show the direction of motion of the
steam and condensing water.
At s. the compartment walls are shown radially and at t. annularly corrugated.

invention and in what manner the same is to be performed I declare that what I
claim is
"
First. In condensers the combination of duplex or double walled cellular com-
partments with a chamber or casing and steam and water connections substantially
as set forth,
Second. The combination of the chamber a. with compartments formed with
double walls f. g. and inlet and outlet ways substantially as set forth.
Third. The combination of chamber compartments and fluid directing appliances
substantially as set forth.
