Improvements in Condensers for Condensing Steam.
We, JOHN GEORGE CHAMBERLAIN and RALPII PLAYER, trading as Joseph Wright
and Company, of Tipton, in the County of Stafford, and of 124, Victoria Street,
in the City of Westminster, Engineers, and JAMES RADCLIFFE, Engineer to the
said Joseph Wright and Company, do hereby declare the nature of this invention
to be as follows:--
This invention relates to condensers for condensing steam such as are used for
instance for condensing the exhaust steam from engines and has for its object
to provide an efficient condenser with but few joints and which will allow of ready
inspection cleaning and repair and in which the tubes can freely expand and
contract without injury to the apparatus. According to this invention a casting,
or steam chest is mounted on suitable feet, or supports, and preferably upon a
base forming a receptacle for the water to be employed in the condenser. The
said casting or steam chest, is divided by partitions into chambers into the first
of which the exhaust steam enters and from the last of which the outlet to the
air pump passes. Set in the sides of these chambers are tubes extending out
sideways therefrom and sustained by any suitable support, or supports, the said
tubes being of shape and their respective ends being connected one to one
chamber and the other to the next chamber so that steam admitted to the first
chamber passes therefrom through some of the tubes then into the next chamber
and thence through other of the tubes to the next chamber and so on in accordance
with the number of chambers and sets of tubes used. The ends of the tubes are
expanded into one side of the casting or steam chest and covers or doors at the
opposite side allow of ready access to the tubes.
The said casting or steam chest containing the said chambers is preferably
recessed so that those tubes which are within the bends of the other tubes of a
set, and therefore do not extend so far outwards, extend further inwards at the
ends which join the casting or steam chest so that all the tubes are of the same
length.
Water is passed by a pump or otherwise from the receptacle which forms
the base, or from other source, through pipes which are arranged over each
of the sets of tubes communicating with the said chambers the said water tubes
having preferably branches where necessary to bring them into proximity to
parts of the tubes which otherwise would not receive water from the water tubes.
The said water tubes are perforated and provided with controlling taps so that
the water is supplied over the exteriors of the whole of steam tubes to assist
the air which passes around the tubes in the condensation of the steam.
The exteriors of the steam tubes may be provided with ribs or wings project-
ing from the sides or bottom or both so as to assist in the distribution of the
water over the tubes.

and Company, of Tipton, in the County of Stafford, and of 124, Victoria Street,
in the City of Westminster, Engineers, and JAMES RADCLIFFE, Engineer to the
said Joseph Wright and Company, 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 relates to condensers for condensing steam such as are used, for
instance, for condensing the exhaust steam from engines, and has for its object
to provide an efficient condenser with but few joints and which will allow of ready
inspection, cleaning, and repair, and in which the tubes can freely expand and
contract without injury to the apparatus.
We will describe this invention-with-reference to the accompanying drawing.
Fig. 1 is a longitudinal vertical section, Fig. 2 a plan and Fig. 3 a transverse
section on the line 12 Fig. 1 of a condenser constructed according to this
invention.
A-casting,-or-steam_chest, A, is mounted on feet, or supports, A2, and pre-
ferably upon a base B, forming a receptacle for the water to be employed-in-the-
condenser. The said casting, or steam chest, A, is divided by partitions a,
into chambers C, C2, C3, into the first of which, (C), the exhaust steam enters,
-by-a-pipe connected at d, and to the last of which, (C³), the outlet to the air
pump is connected at e. Set in the sides of these chambers-are-tubes-D, D2,
extending sideways therefrom and sustained by any suitable support, or supports,
such as is shewn at f, for example, the said tubes being of shape and their
respective ends being connected, one to one chamber and the other to the next
chamber, so that steam-admitted to the _first_ chamber C, passes
therefrom through some of the tubes, then into the next chamber C;
and thence, through other of the tubes, to the next chamber C³,
and so in accordance with the number of chambers and sets of tubes used, as it
is to be understood that the invention is not limited to the use of the number
of chambers and sets of tubes shewn in the drawing. The ends of the tubes
D, D2, are expanded into one side of the casting, or steam chest, A, and open-
ings, a², at the other side, allow of ready access to the tubes when the covers.
or doors, a³, which normally close the said openings, are removed. The said
casting, or steam chest, A, is preferably recessed, as shewn at C, so that the
tubes D2, which are within the bends of the other tubes D, of a set, and there-
fore do not extend so far outwards, extend further inwards at the ends which
join the casting, or steam chest, A, so that all the tubes are of the same length.
Water is passed by a pump, or otherwise, from the receptacle B, which forms
the base, or from other source, through pipes F, which are arranged over each
of the sets of tubes D, D2, the said water pipes having, preferably, branches f
where necessary, to discharge water onto those parts of the tubes D2, which
otherwise would not receive water from the water pipes. The said water pipes
are perforated and provided with controlling taps so that the water is supplied
as desired over the exteriors of the whole of the tubes D, D2, to assist the air,
which passes around the tubes, in the condensation of the steam.
The exteriors of the steam tubes D, D2, may be provided with ribs, or wings,
projecting from the sides, or bottom, or both, so as to assist in the distribution
of the water over the tubes.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we
claim is:-
1. A steam condenser constructed, or arranged, substantially as hereinbefore
described and illustrated in the accompanying drawings.
2. In a steam condenser; a casting, or steam chest, divided into chambers,
and having bent tubes projecting from the sides thereof, and with their ends
communicating with the said chambers, so that the steam passes through the
series of chambers and sets of tubes, substantially as herein before described.
3. In a steam condenser; a casting or steam chest, divided into chambers,
and having bent tubes projecting from the sides thereof, and with their ends
communicating with the said chambers so that the steam passes through the
series of chambers and sets of tubes; the said casting, or steam chest, being
recessed, so that the tubes are all of the same length; substantially as herein-
before described.
