:I, CHARLES SPENCER MADAN of 21 Mansfield. Chambers, St Ann's Square,
Manchester, in the county of Lancaster, Engineer, do hereby declare the nature of
my invention for IMPROVEMENTS IN STEAM JET PUMPS, OR APPARATUS FOR
RAISING & FORCING FLUIDS, to be as follows:-
My Invention relates to an improved combination and construction of Water
Lifters or Apparatus for raising and forcing fluids by the use of certain special
angles and proportions in the making of the various nozzles the properties of
ruising and forcing being improved thereby and the quantity of fluid delivered
increased.
+
The Water Lifter consists of a hollow cylindrical casting prepared at the one end
to receive the steam 'nozzle, and at the other end to receive the combining nozzle
and having a branch at the side, which forms the water connection. The steam
nozzle is held in its place by an ordinary union nut and tail.
Both the water and delivery connections are also supplied with unions. The
combining. nozzle is screwed into the body and is so shaped as to allow the water
to surround the part into which the steam nozzle protrudes, thus keeping the com-
bining.nozzle as nearly at the same temperature as the feed water as possible, and
preventing the water boiling under the action of the steam, and in this way
enabling the lifter to take hotter water than is usual in such apparatus, and giving
it greater power. Also the internal proportions of the combining nozzle give to the
apparatus a superior power of lifting & forcing.

I, CHARLES SPENCER MADAN of, 21 and 22 Mansfield Chambers; St Ann's
Square Manchester in the County of Lancaster, Engineer, do hereby declare the
nature of my invention for IMPROVEMENTS IN STEAM JET PUMPS OR APPARATUS
FOR RAISING AND FORCING FLUIDS 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 an improved combination arrangement and con-
struction of Steam Jet Pumps or Apparatus for raising, and forcing fluids by the
use of certain forms special angles and proportions in the making of the various
nozzles the properties of raising and forcing being improved thereby and the
quantity of fluid delivered increased. The Steam Jet Pump consists of a hollow
cylindrical casting A prepared at the one end to receive the steam nozzle B and at
the other end to receive the combining nozzle C and having a branch D at the side
to admit the fluid it is desired to pump when the Pump is made both to lift and
force, but when made to force only is without a branch, and has holes drilled in the
cylindrical body A to admit the fluid. The steam nozzle B is held in it's place by
an ordinary union nut and tail. Both the admission and delivery connections are
also supplied with unions. The combining nozzle C is screwed into the body and
is.so shaped at the admission end E. E. as to form a hollow cone which allows the
fluid to surround the part into which the steam nozzle B protrudes thus keeping
the combining nozzle C as nearly at the same temperature as the fluid to be
pumped as possible, and preventing the fluid boiling under the action of the steam,
and in this way enabling the Pump to take the fluid hotter than is usual in such
apparatus and giving it greater power. Also the internal proportions of the
combining nozzle C give to the apparatus a superior power of lifting and forcing.
Externally the combining nozzle C is provided with a square for convenience in
screwing it into the body A and is screwed at the delivery end to receive the union
mentioned above. When steam is not available compressed air may be used, in
which case the fluid surrounding the admission end of the combining nozzle C. as
above described keeps the nozzle at about it's own temperature and prevents the
expanding air from freezing the fluid to be pumped while passing through the
nozzle.
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 The combination, arrangement and construction of steam Jet Pumps
substantially as herein before described and illustrated by the drawings

page_text: 2nd The construction and arrangeinent of the admission end of the combining
nozzle of the said steam Jet Pumps in the form of a hollow cone substantially as
herein before described and illustrated by the drawinga.
3rd The alternative use of compressed air for working steam Jet Pumps where
steam is not available substantially as hereinbefore described.
