page_text: We, FRANK PEARN, SINCLAIR PEARN, and THOMAS ADDYMAN, of the firm
Frank Pearn & Co., of West Gorton, near Manchester in the County of Lancaster,
Engineers, do hereby declare the nature of the said invention to be as follows:-
Our invention relates to and consists in the construction and combination and
arrangement of the ram, its cylinder and packing arrangements especially when
the ram is arranged between two columns or pipes which serve as valve chainbers
for the inlet and outlet válves and for the liquid entering and leaving the ram
barrels, and as air chambers and to carry at their upper ends the steam cylinder
and other parts for working the pump.
→
The double acting ram used is connected directly with the piston rod
actuating it.
The lower end of the ram passes through a packing gland or arrangement, and
the upper end of the ram works in a cylinder or casing, the lower end of which is
within and is packed by the said packing ȧrrangement.
The cylinder or casing above named in which the upper part of the ram works
fits or is made to make a fluid tight joint with a casting round it, in which a
passage is formed through which liquid can enter and leave the upper side of the
ram cylinder.
There is also an opening in the casting through which the ram and cylinder or
casing is placed in position, and then this opening is closed by a lid which is
secured in or on the casting fluid tight.
In the lid there is a gland packing for the piston or ram rod to pass through.
There is a passage from the inlet and outlet valve chamber in one column or
pipe to the under side of the ram barrel and a similar passage (before referred to)
from the inlet and outlet valve chamber in the other column or pipe to the upper
side of the ram cylinder.
In some cases we modify our invention by casting the cylinder or casing for the
ram above mentioned in one piece with the lid or we secure the said cylinder
or casing to the lid having the gland in it with holes through the sides opposite
the passage for liquid passing to and from the upper side of the ram barrel or
cylinder.

page_text: We FRANK PEARN, SINCLAIR PEARN and THOMAS ADDYMAN of the firm Frank
Pearn & Co. of West Gorton, near Manchester, in the County of Lancaster,
Engineers 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:-
Our invention will be described by reference to the accompanying drawing
which is an elevation of a steam pump partly in section; Our invention relates to
and consists in the construction and combination and arrangement of the double
acting ram, its cylinder and packing arrangements especially when the ram is
arranged between two columns or pipes, a' and a³ which serve as valve chambers
for the inlet valves b, and outlet valves b¹ and for the liquid entering and leaving
the ram barrel and as air chambers, and to carry at their upper ends the steam
cylinder h, and other parts for working the pump.
The double acting ram o used is connected directly as shown with the piston
rod c actuating it.
The lower end of the ram c passes through a packing gland or arrangement d
and the upper end of the ram works in a cylinder or casing e the lower end of
which is within and is packed by the said packing arrangement d.
The cylinder or casing e above named in which the upper part of the ram c
works, fits or is made to make a fluid tight joint with a casting (f) round it, in
which a passage f' is formed, through which liquid can enter and leave the upper
side of the ram cylinder e.
There is also an opening in the casting through which the ram c and cylinder or
casing e is placed in position and then this opening is closed by a lid g, which is
secured in or on the casting fluid tight.
In the lid g there is a gland packing g' for the piston or ram rod c¹ to pass
through.
There is a passage a* from the inlet and outlet valve chamber in the lower part
of one column or pipe a³ to the under side of the ram barrel and a similar
passage f (before referred to) from the inlet and outlet valve chamber in the
other column or pipe a³ to the upper side of the ram cylinder e.
1.
The lower ends of the columns a³ and a³ are or may be made to communicate
with the hollow base plate i of the pump, which base plate is provided with a
junction for the pipe conveying the water to be pumped. The liquid pumped is
taken from a branch a' from the air columns a² and a³ above the outlet valves b¹.
In some cases we modify our invention by casting the cylinder or casing e for
the ram c above mentioned in one piece, with the lid g, or we secure the said
cylinder or casing e to the lid g having the gland g¹ in it, with holes through the
sides of the cylinder e opposite the passage f¹ for liquid passing to and from the
upper side of the ram barrel or cylinder e.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed-we declare that what
we claim is,
1. The combination and arrangement of the double acting ram, ram barrel,
packing glands and passages substantially as hereinbefore described and illustrated
by the drawing.
2: The combination and arrangement of the double acting ram, ram barrel or
cylinder, gland packing arrangements, valve passages, valves, and columns for
valves, liquid and air vessels, substantially as herein before described and illustrated
by the drawing.
