HENRY DEFTY and CHARLES CHRISTOPHER BRAITHWAITE, both of Queen
Victoria Street, in the City of London, Engineers. "IMPROVEMENTS IN THE
METHOD OF AND APPARATUS FOR UTILIZING AND CONDENSING HEAT BY
COMBUSTION OF COAL, COKE, GAS, AND OTHER SUBSTANCES."
Our Invention relates to a condenser consisting of an arrangement of tubes,
round, square, or oblong, made of metallic metals or other materials. The
construction of such condenser consists of one or more chambers of the above
forms fitted with a series of small chambers or tubes in a transverse forin or order,
so as air, water, or other fluids is allowed to pass through or around the sınall
inserted chambers or tubes, so as in the development of heat acting amongst the
said chambers or tubes is collected and condensed in its passage by heating air or
other fluids by condensation for the purpose of warming or heating buildings or for
other purposes where it may be required.
This condensing arrangement is applicable to domestic, steam, or any other
warming or heating purposes, and the same can be placed immediately over or
to any kind of stove or furnace, thereby all heat generated by combustion is
brought to act amongst the "mesh" of tubes either internally or externally until
consumed by the elements required to be heated for use. This combined condenser
also protects the sweeping action of cold air on the combustion by its encased
form. By this means all combustion is produced pure and clean from oxides and
smoke, the heat being retained in its passage within the condenser until it is
utilized or absorbed for the purposes generated. And all ascending non com-
bustible impurities that are passed off is brought in contact with a small chamber
fitted with a preparation to absorb all noxious carbonaceous acids arising from
such combustion before entering the room or chamber which is required to be
heated. This arrangement can be placed in any ordinary chamber or flue so as to
collect all heat or waste portions thereof that may escape by ordinary use,

Figure 2 is a vertical section of the same shewing another arrangement of
condenser.
Figure 3 shews a half sectional front elevation of the same.
Figure 4 is a side elevation.
Figure 5 shews an elevation of a scraper.
Figure 6 shews an elevation of another arrangement of "mesh ".scraper.
Figure 7 is a sectional plan of the basement.
Figure 8 is a side elevation of the same.
A shews the outside shell of the condenser which may be made of metal or other
materials.
B shews the perforated shell or chamber where the transverse small chambers C
are fixed, and which are inserted or placed within the chamber A.
D shews an arrangement for scraping or cleaning the tubes of the condenser as
may be required, actuated by a knob or handle b.
E shews the fire box protected from the actions of air, and only allowing such
quantities of air as to perfect combustion and retain all heat within the limits of
the condensing surfaces until absorbed by the air or fluids that requires heating.j
F shews the chamber of the escaped gases or impurities where compounds are
placed in a box a to absorb all impurities that may escape.
G shews the horizontal form of such condenser which may be placed in a stack,
flue, or boiler for steam or other purposes.
H shews the ash pan to collect the deposits or incombustible matters that arise
from the fire, and at the same time answers the purpose of a regulator to admit
such quantities of air to perfect combustion.
I shews an arrangement of flue or chamber where the air or fluids are admitted
to pass through the small chambers into the chamber J, whereby such air or fluids
may be collected and conducted through openings K, L, where required.
M shews an oven or boiler for domestic or other purposes.
N shews the combustion generated for domestic use before it arises into the
condenser.
-O-shews the coal pan or hopper which is fixed on the side or in any other
position and enclosed by a lid,-and-the-fire is fed with fuel by means of a screw P.
Q is a fire brick made of refractory material.
R shews the encasement fitted with talc or glass.
S is a small door or lid to examine or repair scraper or tubes.
Having now described our Invention and explained the manner of carrying the
same into effect, we wish it to be understood that under the above in part recited
Letters Patent we clain,-
First. The combination of transverse tubes or chambers to effect an induction of
heat to air or other fluids that required to be heated by combustion.
Second. All combustion and heat generated being protected and manipulated in
it's passage through the "mesh" of chambers whereby it is completely utilized.
In witness whereof, we, the said Henry Defty and Charles Christopher
Braithwaite, have hereunto set our hands and seals, this Twentieth day
of September, in the year of our Lord One thousand eight hundred and
sights are
