PROVISIONAL SPECIFICATION.
Improvements in Pumps for Raising Liquids.
I, THOMAS EDDLESTON of Higher Twistfield Farm Pleasington in the County of
Lancaster, Farmer, do hereby declare the nature of this invention to be as
follows:-
This invention consists of a simple and inexpensive construction of force pump
specially applicable for farm use and for raising liquid manure or other liquids
containing more or less solids in suspension.
According to this my said invention I employ two boxes or cylinders, acting as
barrels of the pump and placed at the bottom of the tank or well made of wood or
metal at the outer end of each barrel is an inlet clack or flap valve. Working
through the opposite and inner ends of the barrels is a piston rod on each end of
which and in the barrels is a piston for drawing or sucking in the liquid into the
barrels and for forcing the same out again by way of the outlet. To the middle of
the piston rod is attached a hand lover working on a fulcrum stud.
The barrels are arranged or laid horizontally on the bottom of the well or tank
submerged in the liquid to be raised, and which on the movement of the piston and
rod by the hand lever flows into one box or barrel by the inlet way or flap valve, and
with the same movement of the hand lever the liquid is forced out of the opposite
barrel or box by the outlet way which is placed above the inlet way or flap valve,
and the outlet ways (one in each box or barrel) are also provided with clack or flap
valves to prevent any return of liquid to the box or barrel.
When the hand lever is worked to and fro a continuous stream of liquid is raised,
both the outlet ways and pipes being merged into one.
The inlet flaps can be screened by wire netting or wire gauze to prevent any refuse
passing through them.

COMPLETE SPECIFICATION.
Improvements in Pumps for Raising Liquids.
I THOMAS EDDLESTON, of Higher Twistfield Farm, Pleasington in the County of
Lancaster, Farmer, 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 :-
This invention consists of a simple, and inexpensive construction of force pump
specially applicable for farm use, and for raising liquid manure, or other liquids
containing more, or less solids in suspension.
According to this my said invention I employ two boxes, or cylinders, acting as
barrels of the pump, and placed at the bottom of the tank, or well; such boxes, or
cylinders are made of wood, or metal, and at the outer end of each barrel is an
inlet "clack" or flap valve. Working through one end of the box, or cylinder is a
piston rod on end of which, and in the barrel is a piston for drawing, or sucking the
liquid into the box, or cylinder, and for forcing the same out again by way of the
outlet. To one end of the piston rod is attached a hand lever working on a
fulcrum stud.
The barrel, boxes, or cylinders are arranged, or laid horizontally on the bottom of
the well, or tank submerged in the liquid to be raised, and which on the movement
of the piston, and rod by the hand lever, flows into one box, or barrel, by the inlet

page_text: way, or flap valve, and with the same movement of the hand lever the liquid is forced
out of the opposite barrel, or box by the outlet way, which is placed above the inlet
way, or flap valve.
The outlet ways (one in each box, or barrel) are also provided with "clack"
flap valves to prevent any return of liquid to the box, or barrel.
"
or
When the hand lever is worked to and fro a continuous stream of liquid is raised,
both the outlet ways, and pipes being merged into one.
The inlet ways can be screened by wire netting, or wire gauze to prevent any
refuse passing through them.
Such being the nature, and object of my said invention, the following is a complete
description of same reference being made to the accompanying drawings, forming
a part of this specification in which :-
Fig. 1. is a side elevation of one of my improved pumps, shewn placed in position
in a well, or tank.
Fig. 2. is a similar view to Fig. 1. the pump being shewn partly in section.
Fig. 3. is a sectional elevation of part of a pump constructed according to my said
invention.
Fig. 4. is a section on line A. B. of Fig. 3.
According to this my said invention I employ two boxes, or cylinders 1. 1. acting
as barrels of the pump, and placed at the bottom of the tank, or well 2; the said
boxes, or cylinders 1. 1. are made of wood, or metal, and are connected by a cylinder 3
in which works a piston 4, of iron, or iron and brass, or copper. At the outer end of
each box, or cylinder 1, is an india rubber, or leather inlet "clack
or flap valve 5
fixed with metal, (preferably copper) fittings, which allows the water, or liquid from
the well or tank 2 to enter the same by the suction of the piston 4.
"
Working through a hole or stuffing box in the flap valve 5 at the end of one of
the boxes, or cylinders 1. is a piston rod 7 on the end of which, and inside the
cylinder 3 is a piston 4, the other end of the piston rod 7 is by link 8 attached to
the hand lever 9 which works on a fulcrum stud 10 in the bracket 11; the said band
lever 9, extending through a slot 12 in the cover 13 of the well, or tank 2, terminates
in a handle for the operator.
The barrels, boxes, or cylinders 1. 1. and cylinder 3 are laid horizontally on the
bottom of the well, or tank, and thus submerged in the liquid to be raised, and which
on the movement of the piston 4 in the cylinder 3, caused by the operator moving
the hand lever 9 to and fro, as shewn by the dotted lines in Fig. 1. flows into one
of the boxes, or cylinders 1, through the inlet way 6, the valve 5 opening, or turning
on its hinges, through the suction, and by the action, or flow of the water, or liquid
to fill the space 1. At the same time that the liquid is being drawn into one of the
boxes, or cylinders 1, the other, and opposite one is being emptied, its contents
being forced up the outlet pipe 14, in the direction indicated by the arrows in
Figs. 2 and 3, the flap valve 5 in the box, or cylinder 1 which is being discharged,
being down, or closing the water inlet way 6. When the hand lever 9 has moved
to the end of its stroke in one direction, and is then moved back, the action is
reversed, the box, or cylinder which was being filled, being discharged of its
contents, and the cylinder or box 1 which was being discharged is then being filled
so that when the pump is in operation, an alternate flow of liquid is maintained up
the two legs 14. 14 and a steady flow from the outlet, or discharge pipe 15 of the
pump.
;
The two legs 14. 14 of the outlet pipe 15 (connected with the boxes, or cylinders 1. 1.)
are provided with "clack"
or flap valves 16 to prevent any return of liquid to the
boxes, or cylinders 1. 1.
The inlet ways 6. 6 may be covered with wire, or by a grate, in order to prevent
any large solid substances getting into the cylinders, or boxes 1. 1.
The Hap valve 5, through which the piston rod 7 works, has a slot 5ª fitting the
piston rod 7 close enough to permit the swinging on its hinges, of the valve 5
without the escape of any appreciable quantity of liquid, especially manure, on the
return stroke of the piston 4,

page_text: In the construction of pumps as aforesaid I am enabled to employ a powerful hand
lever 9 the distance from the handle to the fulcrum 10 being so much greater than
the distance from the fulcrum 10 to the piston rod 7 that a great amount of liquid can
with comparatively easy manipulation be lifted.
Having now particularly described and ascertained the nature, and object of my
said invention, and in what manner the same is to be performed I declare that what
I claim is :-
1. The improvements in pumps, wherein is comprised a piston, and cylinder
between boxes, or cylinders such as 1. 1. the latter provided with inlet flap valves ;
the boxes or cylinders each connected with an outlet pipe, or leg 14 communicating
with a discharge pipe 15, all in combination, as herein described, and substantially
as illustrated by the accompanying drawings.
