Improvements in or relating to Condensers, Water Heaters, and
the like.
I, JAMES WILSON MARTIN, of 29 Corporation Street, Manchester, Engineer and
Machinery Merchant, do hereby declare the nature of this invention to be as
follows:
The object of my invention is to equally distribute the steam entering con-
densers, water heaters, and the like over the surfaces or surface which the steam
acts upon.
For this purpose, instead of the steam entering full bore of the inlet pipe of
condensers, water heaters, and the like, I cause the ingoing steam to pass through
a number of ports or passages, so arranged that the steam on entering is divided
thereby into a number of diverging currents of steam spread over the whole, or
nearly the whole of the surface, surfaces, or tubes to be acted upon. and upon
which they strike or act thereby simultaneously. In cases where the steam
passes through condensing or heating tubes, these passages are so arranged that
steam is made to pass through every tube in approximately the same quantity
at one and the same time. By this means unequal contraction and expansion of
the tubes or condensing and heating surfaces are obviated in their respective
cases, and greater efficiency is obtained.
My improvements are applicable not only to surface and tubular condensers
and water heaters, but also to jet condensers and the like.

Improvements in or relating to Condensers, Water Heaters, and
the like.
I, JAMES WILSON MARTIN, of 29 Corporation Street, Manchester, Engineer and
Machinery Merchant, 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:—
The object of my invention is to equally distribute the steam entering con-
densers, water heaters, and the like over the surfaces or surface which the steam
acts upon.
For this purpose, instead of the steam entering full bore of the inlet pipe of
condensers, water heaters, and the like, I cause the ingoing steam to pass through
a number of ports or passages, so arranged that the steam on entering is divided
thereby into a number of diverging currents of steam spread over the whole, or

page_text: nearly the whole of the surface, surfaces, or tubes to be acted upon; and upon
which they strike or act thereby simultaneously. In cases where the steam
passes through condensing or heating tubes, these passages are so arranged that
steam is made to pass through every tube in approximately the same quantity
at one and the same time. By this means unequal contraction and expansion of
the tubes or condensing and heating surface are obviated in their respective
cases, and greater efficiency is obtained.
My improvements are applicable not only to surface and tubular condensers
and water heaters, but also to jet condensers and the like.
In order that my invention may be fully understood, and more readily carried
out and into effect, I have appended hereunto one sheet of drawings whereon:-
Figure 1 represents a tubular condenser where the exhaust steam passes around
the outside of the water tubes, and with my improvements attached thereto.
Figure 2 represents a surface or tubular condenser where the exhaust steam
passes inside the tubes, the water for condensing purposes being outside; also
with my improvements attached.
Figure 3 represents a tubular and vertical feed water heater-also in sectional
elevation, similar to Figs. 1 and 2-to which my improvements are attached.
Similar letters of reference refer to similar parts throughout the various
figures.
In these figures A is the casing of the condenser and water heater; T, T are
the condensing tubes in the case of the condenser; and the heating tubes in the
case of the water heater; B is the inlet for the exhaust steam, fitted with the
partitions P, P, which forms the subject of my invention, and causes the inlet
branch B to be divided up internally into a number of passages or ports E, E
arranged so that the steam entering B is divided into a number of currents all
acting simultaneously on the tubes T, T, and passes equally around them in the
arrangement shown in Fig. 1; and passes in equal quantities through the
tubes T, T in the arrangements shown in Figs. 2 and 3; by this means unequal
contraction and expansion of the tubes are avoided. C, C, are the outlets for the
exhaust steam; D is the water inlet to the condenser and water heater respectively;
and F is water outlet from same. This invention is also applicable in a similar
manner to jet condensers, water heaters with coiled tubes; and for use with
either exhaust or live steam.
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:
1st. In condensers, water heaters, and the like forming the steam inlet branch
to same with two or more passages E, E by means of the partitions P, P, or by
other suitable device for the purposes specified, and as shown in the drawings
herewith.
2nd. In condensers, water heaters, and the like such as are referred to in the
First Claim, the combination of the partitions P, P and ports E, E with the steam
inlet branch B for the purposes named, and substantially as herein set forth and
illustrated in the drawings herewith.
3rd. The special arrangements, construction, and combination of parts as shown
in Figures 1, 2, and 3 herewith for the purposes named above, and substantially
as described and shown on the drawings herewith.
Dated this 12th day of August 1898.
