The said Invention relates to compound steam pumping engines and accumulators,
more especially of the class for which I obtained British Letters Patent No. 425578
and has for its object to provide combined compound steam pumping engines
and accumulators in which the engines shall start automatically and with certainty
at the required times, and in which the work done shall be performed economically.
One part of my Invention consists in constructing and operating in a novel
manner valves for admitting steam to the low pressure cylinders of compound
pumping engines for the purpose of ensuring that the said engines shall start in
any position of the crank shaft. In carrying this into practice I employ an
ordinary D slide or like valve acting against a face constructed with three ports, of
which one communicates with the low pressure cylinder casing, the second with the
high pressure cylinder exhaust port, and the third with the atmosphere or with a
condenser. The casing containing the said valve is in direct communication with
the steam generator. Motion is given to the said slide valve by a rod attached to
a valve in the delivery pipe arranged and operating substantially as set forth in
the Specification to British Letters Patent No. 2554 granted to me, or motion
may be communicated to the said valve at the required times by gearing from the
accumulator ram or any other suitably moving part of the engines. When the
engines are at rest the said starting valve is in a position which allows steam to
pass direct to the low pressure cylinder valve casing. The exhaust port of the
high pressure cylinder being at the same time open to the atmosphere or to å
037

page_text: condenser. When the engines are in motion the starting valve closes all the three
ports above mentioned. A check valve is provided to prevent steam passing from
the low to the high pressure cylinder.
A further part of my Invention consists in giving motion, to the valve which
controls the admission of water to the condenser of jet condensing accumulator
pumping engines by connecting rod, lever, or like appliance receiving motion from
the gearing which actuates the starting valve under the above first part, or separate
gear may be used for that purpose.
A third part of my Invention consists in actuating the starting and stopping
gear of steam accumulator pumping engines by adjustable mechanism receiving
motion from the accumulator ram for the purpose of allowing work to be done by
the said ram without starting the engines. By the above arrangement when the
demand for water is small the ram is allowed to move a considerable distance
before steam is admitted to the engines.
In carrying the above third part of my Invention into practice under one
modification in which the pressure on the accumulator ram is obtained by steam
acting on a piston I attach to the atmospheric side of the said piston a rod and I
provide the said rod with adjustable collars nuts or equivalent devices which act
so as to open and close a cut off valve admitting steam to the engines, or the said
rod is constructed with fixed collars or equivalent devices and the gearing operating
the cut off valve is made adjustable.

pass direct to the low pressure cylinder valve casing. The exhaust port of the
high pressure cylinder being at the same time open to the atmosphere or to a
condenser. When the engines are in motion the starting valve closes all the three
ports above mentioned. A check valve is provided to prevent strain steam passing
from the low to the high pressure cylinder.
A further part of my Invention consists in giving motion to the valve which
controls the admission of water to the condenser of jet condensing accumulator
pumping engines-by-connecting rod, lever or like appliance-receiving motion-from
the-gearing which actuates the starting valve under the above first part, or separate

A third second part of my Invention consists in actuating the starting and
atopping gear of steam accumulator pumping engines by adjustable mechanism,
receiving motion from the accumulator ram piston, for the purpose of allowing
work to be done by the said ram without starting the engines.
n is
By the above arrangement, when the demand for water is smal
allowed to move a considerable distance before steam is admitted to the engines.
In carrying the above-third this part of my Invention into practice under-one
modification in which the pressure on the accumulator ram is being obtained by
steam acting on a piston, I attach to the atmospheric side of the said piston a rod,
and I provide the said, rod with adjustable collars, nuts, or equivalent devices,
which act so as to open and close a cut off valve, admitting steam to the engines,
or the said rod is constructed with fixed collars or equivalent devices, and the
gearing operating the cut off valve is made adjustable.
Fig. 1 is a side elevation; Fig. 2 a front elevation; and Figs. 3 and 4 detail views
of engines or apparatus constructed under my Invention for pumping and storing
water under pressure.
Under the first part, a is the valve for admitting steam to the low pressure
cylinder, in order to ensure that the said engines shall start with the crank shaft
in any position. The said valve a acts against the face b of the valve box c,
Figs. 2 and 3. The said face 6 has three ports, one of which & communicates through
the chamber e with the low pressure cylinder casing f. A second port g opens
through the chamber h to the high pressure cylinder exhaust port i, and the third
port opens to the atmosphere (or by means of a connecting pipe to a condenser).
The valve box c is in direct communication with the steam generator through the
pipe k, opening into the main steam pipe l. Motion is given to the said valve a by
the rod m attached to a valve in the box n of the delivery pipe o. In the position
shown the engines are at rest, and steam from the generator passes freely through
the port d to the casing of the low pressure cylinder, and the exhaust port of the
high pressure cylinder port-é is open to the atmosphere through the ports g and j,
past the valve a.
It will be seen that when it is desired to start the engines and steam is admitted
to the high pressure cylinder past the throttle valve p, steam will also be admitted
to the low pressure cylinder past the valve a, and that the high pressure cylinder
has a free exhaust. As soon as the engines are in motion and water is being
pumped, the valve in the box c is lifted by the water flowing to the accumulator,
and the valve a moved so as to cover the ports d, g, and j, and the passage of steam
to and from the cylinders is then controlled by the ordinary valve gear.

page_text: Under--the--second part q-is the stem of an ordinary injection cock in the
condenser-7-and is connected by the levers and rods a to the stem-t. The said
stem-t-passes through the valve in the box n to the starting valve a. The
connections--are--se--arranged that when the--engines are at rest as shown the
injection-cock-is-closed. Another arrangement of gear for opening and closing-aÐ
injection-cock under this second part of my Invention is illustrated-in-connection
with the injection-ecek q'.-u levers and rods leading to and connected with-the
starting and stopping lever u'. The said starting and stopping lever u'-receives
motion-automatically in the manner set forth under the third part of my Invention.
Under the third second part, v is a rod attached to the atmospheric side of the
piston of the accumulator w. a is a collar fixed to the said rod v. y, y¹, are trigger
levers connected by gearing to the valve 1, see Fig. 4. 2, exhaust port; 3, pipe
leading from the valve box 4 to the water under pressure in the hydraulic
cylinder 5; 6, port communicating by a pipe, as indicated by the dotted line 7, with
the cylinder 8. In the cylinder 8 works a ram 9, connected by links 10 to the
rod 11. The rod 11 couples the starting and stopping lever u¹ to the throttle
valve p. 12, spring acting to keep the ram 9 at the bottom of the cylinder 8.
The Drawings show the piston of the accumulator in the act of descending, the
collar will therefore be carried down with it until such collar strikes against the
lower trigger lever y; the valve 1 will be moved by the notion of the said trigger
and the gearing = until the port 6 is uncovered. As soon as the port 6 is uncovered,
water under pressure passes from the valve box 4 to the cylinder 8, and the ram 9
is raised against the pressure of the spring 12. The valve 9 in rising opens the
throttle valve, and the engines commence to pump water into the accumulator,
until the collar a strikes against the upper trigger y, and raises it into the position
shown by the dotted lines. The valve 1 will then be moved until the exhaust
ports 3 and 6 are brought into communication, as shown in Fig. 4, and the water.
under pressure will escape from the cylinder 8. The piston will then be caused to
descend by the spring 12, the throttle valve will be closed, and the motion of the
engines arrested until the accumulator piston again descends. The length of
stroke of the accumulator piston may be adjusted by placing the triggers y, y', in
various holes 13, 14. Instead of having moveable triggers, two adjustable collars
may be used. It will be obvious that the various improvements herein set forth
may be applied to steam accumulator pumping engines generally.
Having now described the nature of the said Invention in such manner that
others will be enabled to carry my improvements into effect, I claim :-
First. Valve boxes and valves constructed and operating substantially as set
forth under the first part.
Second. The condenser injection cocks of steam accumulator-pumping-engines
operated--substantially in--the--manner--and for the purposes setforth under-the
second-part.
Third. Second. Starting and stopping gear actuated substantially as set forth in
steam accumulator pumping engines and constructed substantially as herein before
described.

Fig. 1 is a side elevation; Fig. 2 a front elevation; and Figs. 3 and 4, detail views
of engines or apparatus constructed under my Invention for pumping and storing
water under pressure.
Under the first part, a is the valve for admitting steam to the low pressure
cylinder, in order to ensure that the said engines shall start with the crank shaft
in any position. The said valve a acts against the face b of the valve box c,
Figs. 2 and 3. The said face b has three ports, one of which d communicates through
the chamber e with the low pressure cylinder casing f. A second port opens
through the chamber to the high pressure cylinder exhaust port i, and the third
port opens to the atmosphere (or by means of a connecting pipe to a condenser).
The valve box c is in direct communication with the steam generator through the
pipe k, opening into the main steam pipe l. Motion is given to the said valve a by
the rod m attached to a valve in the box n of the delivery pipe o.
In the position
shown the engines are at rest, and steam from the generator passes freely through
the port d to the casing of the low pressure cylinder, and the exhaust port of the
high pressure cylinder port i is open to the atmosphere through the ports y and j,
past the valve a.
It will be seen that when it is desired to start the engines and steam is admitted

and the valve a moved so as to cover the ports d, g, and j, and the passage of steam
to and from the cylinders is controlled by the ordinary valve gear.

page_text: Under the second part q is the stem of an ordinary injection cock in the
condenser r, and is connected by the levers and rods 8 to the stem t. The said
stemt passes through the valve in the box n to the starting valve a. The
connections are so arranged, that when the engines are at rest, as shown, the
injection cock is closed. Another arrangement of gear for opening and closing an
injection cock under this second part of my Invention is illustrated in connection
with the injection cock q¹. u, levers and rods leading to and connected with the
starting and stopping lever u¹. The said starting and stopping lever u' receives
motion automatically in the manner set forth under the third part of my Invention.
Under the third part v is a rod attached to the atmospheric side of the piston of
the accumulator w. is a collar fixed to the said rod v. y, y¹, aro trigger
levers connected by gearing to the valve 1, see Fig. 4. 2, exhaust port; 3, pipe

rod 11. The rod 11 couples the starting and stopping lever u to the throttle
valve p. 12, spring acting to keep the ram 9 at the bottom of the cylinder 8.
The Drawings show the piston of the accumulator in the act of descending, the
collar will therefore be carried down with it until such collar strikes against the
lower trigger lever y; the valve 1 will be moved by the motion of the said trigger
and the gearings until the port 6 is uncovered. As soon as the port G is uncovered,
water under pressure passes from the valve box 4 to the cylinder S, and the ram 9
is raised against the pressure of the spring 12. The valve 9 in rising opens the
throttle valve, and the engines commence to pump water into the accuinulator,
until the collar strikes against the upper trigger y', and raises it into the position
shown-by-the dotted lines. The valve 1 will then be moved until the exhaust
ports 3' and 6 are brought into communication, as shewn in Fig. 4, and the water
under pressure will escape from the cylinder 8. The piston will then be caused to
descend by the spring 12, the throttle valve will be closed, and the motion of the
engines arrested until the accumulator piston again descends. The length of
