PROVISIONAL SPECIFICATION.
Improvements in Pumps and Pumping Engines.
We, WILLIAM HENRY BAILEY, of the firm of W. H. Bailey and Company
Limited, of the Albion Works, Salford, in the County of Lancaster, Brassfounders,
and GUSTAVE LINDEMANN, of the same place, Engineer, do hereby declare the
nature of this invention to be as follows:-
Our invention relates particularly to improvements in those pumping engines
such as sinking pumps in which a ram or rams in combination with a steam cylinder
is employed but our improvements can be applied to pumps actuated by a separate
motor.
In applying our improvements to a pump for well sinking we employ a suitable
steam cylinder, the piston rod of which passes through the bottom of the cylinder
and is connected to a pair of cylinders or pump barrels in each of which is fitted a
hollow piston or guide the first hollow piston forming part of the discharge pipe for
the water; the second hollow piston is in communication with or forms an air vessel.
To the pair of cylinders or pump barrels is connected the hollow ram of the pump
cylinder which latter is fitted with a suitable number of lifting valves near the
bottom the other lifting valves being fitted at the base of the two cylinders near
the top of the hollow ram. A snifting valve or valves is placed above or below the
valves at the bottom of the pump cylinder and in order to connect the different
parts of the pump together suitable tie rods are secured between the steam cylinder
and pump
cylinder the whole machine being suspended by chains when employed in
sinking wells.
The above mentioned air vessel obtains a supply of air from the snifting valve or
valves and serves to prevent shocks when the pump valves operate.
In our improved pump the steam cylinder, the hollow pistons and the main pump
barrel remain stationary, the two cylinders or pump barrels with the main ram
being moved by the piston rod of the steam cylinder the moving parts being guided
by the two stationary hollow pistons.
In case of a separate motor being employed to operate the pump it would be
necessary to apply the power to move the two pump barrels and the main ram.

COMPLETE SPECIFICATION.
Improvements in Pumps and Pumping Engines.
We, WILLIAM HENRY BAILEY, of the firm of W. H. Bailey and Company
Limited, of the Albion Works, Salford, in the County of Lancaster, Brassfounders,
and GUSTAVE LINDEMANN, of the same place, Engineer, 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 relates particularly to improvements in those pumping engines
such as sinking pumps in which a ram or rams in combination with a steam cylinder
is employed but our improvements can be applied to pumps actuated by a separate
motor.
In applying our improvements to a pump for well sinking we employ a suitable
steam cylinder, the piston rod of which passes through the bottom of the cylinder
and is connected to a pair of cylinders or pump barrels in each of which is fitted a
hollow piston or guide the first hollow piston forming part of the discharge pipe for

page_text: the water; the second hollow piston is in communication with or forms an air vessel.
To the pair of cylinders or pump barrels is connected the hollow ram of the pump
cylinder which latter is fitted with a suitable number of lifting valves near the
bottom the other lifting valves being fitted at the base of the two cylinders near
the top of the hollow ram. A snifting valve or valves is placed above or below the
valves at the bottom of the pump cylinder and in order to connect the different
parts of the pump together suitable tie rods are secured between the steam cylinder
and pump cylinder the whole machine being suspended by chains when employed in
sinking wells.
The above mentioned air vessel obtains a supply of air from the snifting valve or
valves and serves to prevent shocks when the pump valves operate.
In our improved pump the steam cylinder, the hollow pistons and the main pump
barrel remain stationary, the two cylinders or pump barrels with the main ram
being moved by the piston rod of the steam cylinder the moving parts being guided
by the two stationary hollow pistons.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 represents a sectional elevation and Fig. 2 an elevation of a pump for well
sinking to which our invention is applied. Fig. 3 is a sectional plan of part of the
pump.
a is the steam cylinder in which works the piston rod to which are secured the
pump barrels or cylinders c and d to which are fixed the hollow ram e¹; ee are the
lifting valves; e¹ and d¹ are hollow pistons or guides secured to or near to
the bottom of the cylinder a; the piston c' forms part of, or is connected to, the
discharge pipe c² and the piston d' forms an air vessel; the pump barrels c and d
slide on the pistons or guides c' and d' which together constitute well balanced
guides and enable the pump to work smoothly and without side strain. is the
pump cylinder in which the ram e' slides; h is the snifting valve and g g are the
lifting valves at the bottom of the cylinder f; i is the inlet pipe; ij are tie rods
which connect the pump cylinder f to the steam cylinder a and k k are chains by
which the pump is suspended.
The mode of operation is as follows:-
:-
When steam is admitted to the cylinder a the piston 6 moves downward and
carries with it the pump barrels c and d and the hollow ram e', the valves e e
lifting; when the piston b barrels c and d and ram e' rise the valves e e are closed
and some of the water above the valves ee is discharged through the pipe c².
The snifting valve / admits air into the pump barrel f as usual and a portion of
the said air finds its way to the air chamber in the hollow piston d'.
In case of a separate motor being employed to operate the pump it would be
necessary to apply the power to move the two pump barrels and the main ram.
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. In pumps and pumping engines the combination with the hollow piston or
guide which forms part of the discharge pipe and on which the pump barrel slides,
of an additional guide on which the pump barrel also slides.
2. The combination with the hollow piston or guide which forms part of the
discharge pipe and on which the pump barrel slides of a hollow piston or guide
which forms an air chamber and on which the pump barrel also slides substantially
as and for the purposes herein described.
