Improvements in Lift and Lift and Force Pumps or other Pumps
where Leverage is Required.
I WILLIAM GOULD of Station Street Tutbury near Burton-on-Trent in the County
of Stafford Builder and Contractor do hereby declare the nature of this Invention to
be as follows:
My invention consists of the construction and combination of the parts of mechanism
herein after described for working or giving a reciprocating motion to the pump rods
of lift and lift and force pumps or other pumps where leverage is required whereby a
uniform force through the whole of the stroke of the pump rod is imparted to the said
rod combined with a very steady motion in the said rod and a longer length of stroke
can be more conveniently obtained than by the ordinary arrangement for working
together with facility of working.
Instead of operating the pump rod by means of a lever or handle jointed directly, to
the upper end of the pump rod as usual 1 employ mechanism constructed and operated
in the manner hereinafter described. On the standards or uprights of the pump I
support a horizontal axis the bearings for the said axis being supported preferably on
angle plates fixed to the said standards. The said axis has keyed to it a pulley or
drum by means of which and the other appliances herein. after described the pump rod
is worked. The said pulley or drum is divided near its middle by two flanges
separated a short distance apart. These flanges assist in guiding the pump rod in its
motion. On the periphery of each division of the divided pulley or drum one end of
a chain is fixed the other ends of the said chains being connected respectively to the
top and bottom of the head of the reciprocating pump rod. The said chains are so
fixed to. and arranged on the periphery of the pulley or drum that as the said pulley
rotates in one or other direction one of the said chains is wound upon it and the other chain
is at the same time unwound from off it. The head of the pump rod is made preferably
of a T form in cross section the parts on either side the middle flange of the shaped
head constituting seats for the chains attached to it and to the pulley or drum. The
middle flange of the T shaped head works between the flanges on the pulley or drum
and assists in guiding the pump rod.
A reciprocating partial rotary or rocking motion through any required angle is
given to the chain pulley or drum by means of a handlever or handle fixed on the
projecting end of the axis or shaft of the said pulley or drum. By giving an up and
down motion to the said hand lever a backward and forward or alternating motion
through about a semi-circle is given to the said pulley or drum and the chains
connected to it and to the head of the. pump rod are alternately wound upon and
unwound from the said pulley or drum and a reciprocating motion thereby given
to the pump rod the force imparted to the said rod being very uniform and its motion
very steady. By varying the diameter of the chain pulley or drum and the angle
through which the hand lever works the stroke of the pump rod may be varied. The
chain which is connected to the upper part of the head of the pump rod may be
connected thereto by an adjustable connection.
Although I prefer to give the alternating rotary motion to the chain pulley or drum
by means of a hand worked' lever yet the said chain pulley or drum,may be worked
by a winch or by steam or other power.

Improvements in Lift and Lift and Force Pumps or other Pumps
where Leverage is Required.
I WILLIAM GOULD of Station Street, Tütbury near Burton-on-Trent in the County
of Stafford Builder and Contractor do hereby declare the nature of my invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention consists of the construction and combination of the parts of
mechanism hereinafter described for working or giving a reciprocating motion to
the pump rods of lift and lift and force pumps or other pumps where leverage is
required, whereby a uniform force through the whole of the stroke of the pump rod is
imparted to the said rod combined with a very steady motion in the said rod and a
greater length of stroke can be more conveniently obtained than by the ordinary
arrangement for working, together with facility of working.
Instead of operating the pump rod by means of a lever or handle jointed directly to
the upper end of the pump rod as usual, I employ mechanism constructed and operated
in the manner hereinafter described.
On the standard or upright of the pump I support a horizontal axis the bearings for
the said axis being supported preferably on angle platos fixed to the said standards.
The said axis has keyed to it a pulley or drum by means of which and the other
appliances hereinafter described the pump rod is worked. The said pulley or drum is
divided near its middle by two flanges separated a short distance apart.
These flanges assist in guiding the pump rod in its motion. On the periphery of
each division of the divided pulley or drum one end of a chain is fixed, the other ends
of the said chains being connected respectively to the top and bottom of the head of
the reciprocating pump rod. The said chains are so fixed to and arranged on the
periphery of the pulley or drum that as the said pulley rotates in one or other direction
one of the said chains is wound upon it and the other chain is at the same time
unwound from off it. The head of the pump rod is made preferably of a Ț form in
cross section the parts on either side the middle flange of the T shaped head con-
stituting seats for the chains attached to it and to the pulley or drum. The middle
flange of the T shaped head works between the flanges on the pulley or drum and
assists in guiding the pump rod.
A reciprocating partial rotary or rocking motion through any required angle is
given to the chain pulley or drum by means of a hand lever or handle fixed on the
projecting end of the axis or shaft of the said pulley or drum. By giving an up and
down motion to the said hand lever a backward and forward or alternating notion
through about a semi-circle is given to the said pulley or drum, and the chains
connected to it, and to the head of the pump rod, are alternately wound upon and
unwound from the said pulley or drum and a reciprocating motion thereby given to
the pump rod, the force imparted to the said rod being very uniform and its motion
very steady.
Figure 1 of the accompanying Drawing represents in side elevation: Figure 2 in
front elevation and Figure 3 in plan, mechanism the parts of which are constructed
and combined according to my invention for giving a reciprocating motion to the
pump rods of lift and other pumps. Figure 4 represents a plan partly in horizonta
section, of the same with the connecting chains omitted. The pump cylinder, pum
bucket or piston and other adjuncts of a pump I have not thought it necessary to
represent as the said parts are of the ordinary kind and constitute no part of my
invention.
The same letters of reference indicate the same parts in the several Figures of th
Drawing.
a is the standard or upright on which the mechanism is supported; d is the pum
rod and e is the head of the pump rod. The said head c has a form in cross sectio

page_text: as best seen in Figure 4 and is for the purpose hereinafter explained; but I do not
limit myself to the use of a T shaped head to the pump rod.
b, b is the pulley or drum carried by the horizontal axis e which is supported and
turns in the bearings or bearing plates fffixed to the standard or upright a.
On the projecting end of the axis e of the pulley or drum is a handle or hand lever y
for working the pump. The periphery of the pulley or drum is divided into two
parts marked respectively and by the flanges 63, the said flanges being separated
a short distance apart (see Figures 3 and 4). Between the two flanges of the
pulley or drum, the middle rib of the T shaped head e of the pump rod works (see
Figure 4) and assists in guiding the said head and the pump rod attached to it. The
flanges act as bearing cheeks for the chains h. i by which the pump rod head e is
connected to the pulley or drum b, 2, the said chains working respectively on the two
parts of the said pulley or drum. To the periph ry of the part of the pulley or
drum, one end of the chain h is fixed at h², the other end of the chain h being fixed at
h³ to the top of the pump rod head c. To the periphery of the part of the pulley or
drum, one end of the chain is fixed at 2, the other end of the said clain i being fixed
to the bottom of the pump rod head e at 3. It will be seen by an examination of
Figure 3 that the ends of the chains h. i are connected in the same line at the two
parts of the pulley, the two chains h. i being coiled on the pulley in opposite
directions.
The connection at 3 by which the upper part of the chain his connected to the
head e is adjustable as represented for tightening the chain on the pulley.
By arranging the chains h. i on the peripheries of the two parts of the pulley or
drum and connecting them to the head of the pump rod in the manner described and
represented, the rotation of the said pulley in one or other direction causes one of the
chains to be wound upon it and the other chain at the same time to be unwound from
In the drawing, the chain i is represented wound upon the pulley and the pump
rod lifted nearly to the end of its upward stroke, the chain being nearly unwound
from the pulley.
it.
The reciprocating partial rotation or rocking motion is given to the chain pulley o
drum b. by means of the band lever or handle g, which is moved up and down after.
the manner of an ordinary pump handle. By the motion of the hand lever g, a back-
ward and forward, or alternating motion through about a semi-circle, or other portion
of a circle, is given to the pulley or drum b, and the chains h. i, connected to it and
to the head c of the pump rod d in the manner herein before described, are alternately
wound upon and unwound from the pulley or drum and a reciprocating motion
thereby given to the pump rod, the force imparted to the said rod being very uniform
and its motion very steady.
As the pump rod head e is raised and lowered it is guided by its rib working
between the flanges 63 of the pulley. The rectilinear motion of the pump rod is
preserved by the pump bucket or piston working in the pump cylinder.
By varying the diameter of the chain pulley or drum and the angle through which
the land lever works the stroke of the pump rod may be varied.
Although I prefer to give the alternating rotary motion to the chain pulley or drum
5 by means of a hand worked lever as described and represented, yet the said chain
pulley or drum may be worked by a winch or by steam or other power.
I do not liinit myself to supporting the mechanism on an upright or standard as it
may be supported on a wall bracket or other support, or enclosed in a box or case.
Having now particularly described and ascertained the nature of my Invention
0 and the manner in which the same is to be performed 1 declare that I claim
as my invention of "Improvements in lift and lift and force pumps or other pumps
where leverage is required "-
The construction and combination of the parts of the mechanism hereinbefore
described and illustrated in the accompanying drawing for working or giving a
5 reciprocating motion to the pump rods of lift and other pumps; that is to say,
mechanism consisting essentially of a pulley or drum to which an alternating motion

page_text: through about a semi-circle or other, angleris given by hand or other power,.the said:
pulley or drum being connected to the head of the pump rod by means of 'two chains,.
One end of each of the said chains; being fixed to the periphery of the pulley or drum
and the other ends of the said. chains being, connected respectively to the topcand
bottom of the pump rod head,,the said chains being: so fixed to. and arranged on the
periphery of the pulley or drum that. as a partial rotation is given to the pulley on
drum. in one or other direction, one of the chains is wound upon it.and, the other chain
is at the same time unwound. from:it and a reciprocating motion thereby given to the
pump rod substantially as described and illustrated.
