Improvements in Hydraulic Pumps.
A communication from JAMES WILLIAM ANDERSON, of the Town of Aylmer, in
the Province of Ontario, Canada, Manufacturer.
I ALFRED GEORGE BROWNING, Gas Engineer 6 Entwistle Street Whitworth
Park Manchester in the County of Lancashire do hereby declare the nature of
this invention to be as follows:-
-
The first part relates to an air chamber & conducting pipe constructed of two
pieces connected by an elbow at the bottom of the air chamber having on the top a
lug or working bearing to receive the handle, and the rods that connect the pump
with handle extend to the working cylinders.
Secondly relates to the cylinders and waterway that connect them with the
conducting pipe. First the Y-shaped yoke or waterway is tapped at the top to
receive connecting pipe which extends to the elbow connecting air chamber &
delivery. To the bottom of this yoke two cylinders are attached extending
downward, in the bottom of each of which there is a valve which plays up & down
inside the cylinders.
Thirdly relates to the outside or working cylinders, which are attached to the
rods extending to the handle by means of a fork which is attached by a pivot or
stud on either side of the cylinder. These cylinders by the action of the handle
are worked alternately up and down over the inner cylinder one outside cylinder
filling while the other is exhausting these also have valves in the bottom of each.
Fourthly relates to the rods attached to the handles whereby any desired
leverage may be obtained by shifting the rods to or from the centre."

A communication from JAMES WILLIAM ANDERSON, of the Town of Aylmer, in
the Province of Ontario, Canada, Manufacturer.
I ALFRED GEORGE BROWNING, Gas Engineer, 6, Entwistle Street, Whitworth
Park, Manchester in the County of Lancaster 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 first part relates to an air chamber and conducting pipe, constructed of two
pieces, connected at the bottom by a branch elbow; and at the top of the air
chamber there is a lug or bearing to receive the handle or working lever. The
rods that connect the pump with the handle or working lever extend downward to
the working cylinders, being attached to the handle or working lever on each side
of the fulcrum at equal distances; which ensures the balancing of the working
parts at any depth: the tension or strain is always upwards: there being no force
on the rod as it descends.

page_text: The second part relates to the cylinders and water way that connect them with
the conducting pipe. The Y shaped yoke or water way is connected at the top to
the conducting pipe which extends to the branch elbow; connecting air chamber
and continuation of conducting pipe. At the bottom of this yoke two cylinders
are attached extending downwards, in the bottom of each of which there is a
valve.
The third part relates to the outside or working cylinders, which also have
valves in the bottom of each; and which are attached to the rods connecting the
handle or lever by means of a fork, which is attached by a pivot or stud on either
side of the cylinder, these cylinders by the action of the handle or working lever
are worked alternately up and down over the inside cylinder, one outside cylinder
filling whilst the other is exhausting, thereby producing a continuous force stream.
The fourth part relates to the mode by which the working rods are attached to
the handle or working lever whereby any desired leverage may be obtained by
shifting the rods to or from the centre.
In order that this invention may be clearly understood I have annexed a sheet
of drawings illustrative thereof and have marked the same with figures and letters
of reference corresponding with those of the following description thereof.
Fig. 1 is a sectional view of a well shewing in elevation one of my improved
hydraulic pumps applied thereto,
Fig. 2 is a section of part of the pump detached and drawn to a larger scale.
On Fig. 1a is the air chamber and the conducting pipe connected together by
the branch elbow b, c is the handle or working lever mounted on the pivot c¹ at
the top of the air chamber a; d d are the rods which connect the handle or
working levere to the working cylinders e e' respectively.
fis the Y shaped yoke connected at the top to the conducting pipe f' leading to
the pipe and air chamber a, the two branches of the said yoke f being attached
to the fixed cylinders g g extending downwards the cylinder 9 being shewn
enlarged and in section on Fig. 2.
Each of the cylinders e e' is provided with a valve (see h Fig. 2) at the lower
end thereof, the said cylinders e e¹ being attached, as seen at Fig. 2, to the
rods d d by forks (see d+ Fig. 2) and being worked by the handle or lever c over
the fixed cylinders g g'.
Each of the cylinders g g' is provided with a valve (see Fig. 2) the valve his
closed and the valve i opened as the cylinder e rises and the valve h opens and the
valve i closes as the cylinder e descends; and as the cylinders e and e¹ always
move in contrary directions a continuous forced stream of water or fluid is produced,
without any severe thrust upon the rods d dr.
с
The handle or lever c is provided with more than one point of attachment for
the ends of the rods d and it (see Fig. 1) or it may be made with a slot or slots so
that any desired leverage can be obtained by shitting the rods and nearer to
or further from the centre c'.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The combination and arrangement of parts forming an improved hydraulic
pump substantially as hereinbefore described and illustrated by the annexed
drawings.
