[Communicated from abroad by WILLIAM CRAIG, Engineer, of Gates Avenue, in the
City of Brooklyn, State of New York, United States of America.]
I PHILIP ARTHUR NEWTON of the Office for Patents, 6 Bream's Buildings Chancery
Lane in the County of Middlesex, Patent Agent, 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 inventor describes his invention as follows:-
My invention is more particularly intended to be applied to the suction pipes of
pumps, so that the water which supplies the pump will be made effective in condensing
the steam employed to drive the pump-operating engine; but the invention is also
applicable to condensers employed for steam engines, vacuum pans, and other
purposes.
The condenser which forms the subject of my invention comprises a body made in
a suitable casting and an upper chamber which has inlets for steam and water, and
which communicates by a throat with the body, and in the throat is arranged a valve
which controls the flow of water into the body of the condenser, and is connected
with a float for varying the inflow of water according as the level of water in the
condenser rises or falls. In order that the water entering the body of the condenser
shall not, in its fall, disturb the float, I provide a pipe or passage which leads down-
ward from the throat to, or slightly below the level of water in the body; and the float
is arranged laterally beyond this pipe or passage, and is in preference made of
annular form, loosely surrounding, but not fitting, the exterior of the pipe or passage.
The float may be connected with a guiding frame or spider which is arranged below
the end of the downwardly extending pipe or passage, and is connected by a rod
with the valve in the throat, and opposite the valve in the throat, I preferably arrange
J

page_text: Coon Yarr WHICH May be adjusted upward or downward by nana from the exterior
of the condenser.
When the condenser is employed in connection with a steam pump, the valve
which controls the flow of water through the throat into the body of the condenser
may be connected in any convenient manner with the throttle valve, whereby the
supply of steam to the direct acting or other engine which operates the pump may be
controlled; and both these valves may be connected with, and operated simultaneously
by, the float.
Indeed, if the condenser be employed in connection with an engine used for power
purposes other than operating a pump piston, the float may be dispensed with, and the
connections between the valve which controls the flow of water through the throat of
the condenser and the throttle valve or other analogous device which controls the
supply of steam to the engine, will ensure the simultaneous adjustment of said water
controlling valve and throttle valve or device, to correspondingly increase or diminish
the flow of water and supply of steam.
In the accompanying drawing :-
Fig. 1 represents a vertical section of a condenser embodying my invention,
including a throttle valve which is connected with the float; and
Fig. 2 is a horizontal section upon about the plane indicated by the dotted line a a
Fig. 1.
Similar letters of reference designate corresponding parts in both Figures.
A designates the body of the condenser, which may be of cast metal, and which has
at the bottom an outlet A', through which it is connected with the suction pipe of the
pump. The casing or body A is surmounted by a head A2, having cored within it
à chamber A³. With the chamber A³ communicates an inlet A4 for the portion of
the suction pipe which extends to the condensers. In this example of my invention,
the inlet or branch A', for connection with the suction pipe, is formed upon the body A,
and the port or passage & leading therefrom to the chamber A³ constitutes a water
inlet to such upper chamber. A designates the steam inlet, and, as here represented,
I have shown two branches or .inlets A at right angles to each other, so that the
steam pipe, whatever be the direction from which it leads to the condenser, may be
conveniently connected therewith.
b
The upper chamber A³ communicates with the body A of the condenser by a
throat, in which I have represented a ring-shaped valve B, and directly opposite
this valve and throat, and in the steam inlet, I have represented a second ring-shaped
valve C.
'
From the throat a pipe or passage D extends downward into the body of the
condenser, and terminates, at its lower end, at about the level of, or slightly below
the water in the condenser. This pipe or passage D is here represented as made
separate from the head A2, and as secured thereto by bolts 62, it being fixed in
position. The steam entering at A', passes downward through the throat b¹, and
through the pipe or passage D, and the water for condensing the steam flows laterally
inward over the edge of the valve B, and through the space e provided between the
two valves B, C. It will therefore be seen that any rising movement of the valve B
will diminish the flow of water through the throat into the body of the condenser.
E designates the float, which is arranged laterally beyond the pipe or passage D,
and which, as here shown, is of annular form loosely surrounding the pipe or passage,
but not in any sense fitting thereon. Inasmuch as the pipe or passage D extends
below the normal position of the float, which is at the water level, the water flowing
through the pipe or passage D will not materially disturb the float. As here
represented, the float is connected with a guiding frame or spider E', which may rest
upon a ledge or shoulder e projecting inward from the body of the condenser, and
which has upwardly extending armis e¹ connected with the float, in this example of
iny invention, by bands e embracing the float. I have here employed four bands for
this purpose, as best shown in Fig. 2, but the number is immaterial.
The guiding frame or spider E' is connected by a rod E2 with the valve B, and it

page_text: will thereby be understood that any rising or falling movement of the float E will
correspondingly affect the valve B.
In this example of my invention the valve is operated by a tubular stem C,
which extends through a stuffing box in the top of the condenser, and is provided
with a hand wheel c², whereby it may be turned, and I have also shown rod E2 as
extending above the valve B, through the tubular stem C, and through the stuffing
box c³ at the top thereof, and connected with the lever E2 which is fulcrumed at e³.
F designates a throttle valve, which is arranged in a section of pipe F¹, and this
pipe may be supposed to be the steam pipe through which steam is supplied to the
pump-operating or other engine in connection with which the condenser is used.
The lever E' is connected by a rod et with the arm on the valve F, and it will
therefore be understood that any rising or falling movement of the float B will not
only diminish or increase the flow of water through the throat into the condenser
body, but will also diminish or increase the flow of steam through the valve F to
operate the engine.
When the condenser is employed in connection with an ordinary steam engine used
for power purposes, the float may be dispensed with, the rod E2 being in such case only
employed to connect the valve B and lever E³ and the throttle valve F; or a governor
or a movable part of an automatic cut off constitutes a device whereby the supply of
steam for operating the engine is controlled. The valve B and the steam-controlling
device are, by the lever E³ and rod E2, so connected that they may be shifted
simultaneously to correspondingly increase or diminish the supply of steam to the
engine, and the supply of water passing through the throat for condensing such
steam. The valve C may be set so as to admit substantially the flow desired through
the space c, and the valve B will vary the flow as the supply of steam may be
increased or diminished.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. The combination with a condenser body and an upper chamber having inlets for
steam and water, and communicating by a throat with the body, of a valve in said
throat, a pipe or passage leading downward from the throat and fixed in position
within the body, a float arranged laterally beyond the pipe or passage, and connections
between said valve and float, substantially as herein described.
2. The combination with a condenser body and an upper chamber having inlets for
steam and water, and communicating by a throat with the body, of a valve in the
throat, a pipe or passage extending downward from the throat, an annular float loosely
surrounding, but not fitting the pipe or passage, and connections between the float and
said valve, substantially as herein described.
3. The combination with the body A, and the upper chamber having inlets for
steam and water, and communicating by a throat b' with the body, of the valve B in
the throat, the pipe or passage D, the annular float E, loosely surrounding the pipe or
passage, the guiding frame or spider E' connected with the float, and the rod E²,
connecting said frame or spider with said valve, substantially as herein described.
,

water inlets, and communicating by a throat b' with the body, of a valve in said
throat, and a throttle valve for controlling the supply of steam for operating a pump,
a float arranged within the condenser body, and connections between the float and said
two valves, whereby the rising movement of the float will diminish the flow of water
through said throat, and will more or less close the throttle valve, substantially as
herein described.
5. The combination with the condenser body and an upper chamber having steam
and water inlets, and communicating by a throat with the body, of the valves CB
arranged opposite each other in the steam inlet and throat, the tubular stem C, for

the valve B and said controlling device, whereby the valve B and said device will be
operated simultaneously, to correspondingly increase or diminish the supply of water
through the throat, and the supply of steam for operating the engine, substantially as
herein described.
