MENTS IN DOUBLE-ACTING LIFT AND FORCE PUMPS."
Year: 1865

page_text: LETTERS PATENT to Charles Denoon Young, of Perth, in the County
of Perth, Scotland, Mechanical Engineer, for the Invention of "IMPROVE
MENTS IN DOUBLE-ACTING LIFT AND FORCE PUMPS."
PROVISIONAL SPECIFICATION left by the said Charles Denoon Young
at the Office of the Commissioners of Patents, with his Petition, on the
4th April 1865.
I, CHARLES DENOON YOUNG, of Perth, in the County of Perth, Scotland,
Mechanical Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN DOUBLE-ACTING LIFT AND FORCE PUMPS," to be as follows:-
The several objects of the Invention of this improvement are to combine
and arrange the parts of the pump together in such a manner as will admit
of readily getting to any one of the valves without interfering with the
others; constructing and arranging the water passages of the pump in com-
bination with the inlet and discharge pipes, with a view to have the pipes
straight and free of bends as possible, for giving as little resistance to the
flow of water through them as practicable; providing each inlet valve with
an independent inlet pipe extending into the dike or well from whence the
water is drawn; also each delivering valve with an independent discharge pipe
extending from the pump to the tank or trough into which the water may be
discharged.
The arrangements of parts by which the stroke of the pump can be
increased or diminished to suit the power for working it.

page_text: The general construction of the pump consists in attaching the cylinder of
it to a suitable frame of iron or wood, and arranging a shaft with gearing or
pullies to the frame for giving motion to the piston of the pump through a
connecting rod and slide guides by means of horse, steam, or other power.
In place of providing the shaft with an ordinary crank, it is furnished with a
disk crank, which is provided with a number of holes at various distances
from the centre of the shaft for attaching the crank pin; by this means the
stroke of the pump can be increased or diminished to suit the power for doing
the work, as before stated, or for increasing and diminishing the quantity of
water pumped. The water passages into each end of the cylinder of the
pump, and to which the valve chambers are attached and brought out of the
side of the pump, so that the pipes will not interfere with the foundations or
framework in attaching them to the pump, and in the meantime retain the
valve chambers, inlet, and discharge pipes in a right line. The inlet valves are
placed below the centre and at the ends of the pump, and the discharge valves
above the centre and directly over the inlet valves; the space between the
inlet and outlet valves lead into the water passage of the cylinder of the pump.
Each valve is provided with an independent bonnet or flange, for getting to
the valves for cleaning and repairs. The valves will be composed of india-
rubber, and a round grated disk of brass fit into the valve chamber. One
air vessel will be arranged over and between the two delivering valves on a
pipe connecting the two discharge pipes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Denoon Young in the Great Seal Patent Office' on
the 30th September 1865.

the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after.the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Denoon Young, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say:-
The several objects of the Invention of this improvement are to combino
and arrange the parts of the pump together in such a manner as will admit
of readily getting to any one of the valves without interfering with the others;
constructing and arranging the water passages of the pump in combination
with the inlet and discharge pipes, with a view to have the pipes straight and
free of bends.as possible, for giving as little resistance to the flow of water
through them as practicable; providing each inlet valve with an independent
inlet pipe extending into the dike or well from whence the water is drawn ;
also each delivery valve with an independent discharge pipe extending from
the pump to the tank or trough into which the water may be discharged.
The arrangements of parts by which the stroke of the pump can be
increased or diminished to suit the power for working it.
The general structure of the pump consists in attaching the cylinder of it
to, a suitable frame of iron or wood, and arranging a shaft with gearing or
pullies to the frame for giving motion to the piston of the pump through a
connecting rod and slide guides by means of horse, steam, or other power. In
place of providing the shaft with an ordinary crank, it is furnished with a disc
crank, which is provided with a number of holes at various distances from the
centre of the shaft for attaching the crank pin; by this means the stroke of
the pump can be increased or diminished to suit the power for doing the
work, as before stated, or for increasing and diminishing the quantity of water
pumped. The water passages into each end of the cylinder of the
pump, and
to which the valve chambers are attached are brought out of the side of the
pump, so that the pipes will not interfere with the foundation or framework in

page_text: attaching them to the pump, and in the meantime retain the valve chamber,
inlet, and discharge pipes in a right line. The inlet valves are placed below
the centre and at the ends of the pump, and the discharge valves above the
centre, and directly over the inlet valves; the space between the inlet and
outlet valves leads into the water passage of the cylinder of the pump. Each
valve is provided with an independent bonnet or flange, for getting to the
valves for cleaning and repairs. The valves will be composed of india-rubber,
and a round grated disc of brass fit into the valve chamber. One air vessel
will be arranged over and between the two delivery valves, or a pipe connecting
the two discharge pipes.
Having thus stated the nature of my said Invention I will proceed more
fully to describe the manner of performing and constructing the same, by
referring to the Drawings forming part of this Specification.
Fig. 1 represents a side elevation of the pump showing its arrangement for
drawing water from a cistern, and forcing it into a tank; Fig. 2 is a plan or
top view of the pump and frame; Fig. 3 is an end elevation of the pump and
tank, showing the mode of arranging the pipes and valve chambers to the
cylinder of the pump.
pump to suit the
to which the disc
A is the barrel or cylinder of the pump, which will be furnished with an
ordinary piston and piston rod made to work through stuffing box at one
end of the cylinder, as represented. The cylinder will be furnished with
flanges for attaching it to the cast-iron frame B, ordinarily the frame B will
be placed on timbers over the cistern; C is a disc crank furnished with four
holes 4, 5, 6, and 7, for attaching the crank pins at various distances from the
centre of the crank or shaft on which it is fastened for the purpose of
lessening or increasing the length of the stroke of the
power applied or quantity of water required. The shaft
crank is attached will be furnished with pullies or gear wheels, by which
motion will be given to the piston of the pump through the connecting
rod D; F are slides for guiding the cross head, to which cross head the
piston of the pump and connecting rod D is attached, as shewn in Figs. 1
and 2; 0, 0, are pipes furnished with valve chambers K, K, and G, G,
which are joined to the ends and sides of the cylinder A by flanges, as shewn
in Fig. 3; G, G, are the inlet valve chambers, and K, K, outlet valve
chambers; each valve chamber is furnished with an independent door or cap
so that any one of the valves may be got at without interfering with the
others; any of the ordinary structures of valves may be employed, but by
preference the india-rubber sheet or clack valve will be preferred; H, H, are
inlet pipes attached to the lower end of the valve chamber 0, 0, and

page_text: extending into the cistern J. The lower ends of these pipes are shaped and
provided with holes to make them serve as strainers; b, b, are the discharge
or outlet pipes united to the connecting pipe P, and extending up and
attached to the tank M, M. The connecting pipe P is employed for carrying
the air vessel N, by thus joining the two outlet pipes by the pipe P, but one
air vessel is required for both outlet valves.
In witness whereof, I, the said Charles Denoon Young, have hereunto set
my hand and seal, this Thirtieth day of September, in the year of our
Lord One thousand eight hundred and sixty-five.
CHARLES DENOON YOUNG.
