PROVISIONAL SPECIFICATION.
Improvements in Pumping Apparatus.
We JOSEPH ARMYTAGE WADE, Timber Merchant and Manufacturer of Pumps, and
JOHN CHERRY, Mechanical Engineer, both of Hornsea, in the East Riding of the
County of York, do hereby declare the nature of this invention to be as follows:-
This invention relates to pumping apparatus of the plunger typo and adapted to be
worked by hand, steam or other power.
The objects of the present improvements are to produce a pump combining
simplicity, economy and strength with ease and efficiency in working.
In carrying out our invention as a pump apparatus for raising or forcing liquids,
or any other hydraulic purpose we employ a plunger having one or both ends of
pointed or partially pointed or of wedge form either single or multi-sided and
working within a cylinder furnished with suitable inlet and outlet apertures and
controlled by suitable valves.
The plunger will be provided with either one or more such ends according to the
object for which it is intended.
In the case of a plunger with two such ends it may be connected by. a rod with
the motive power for operating it.
When formed with such single pointed or wedged end the plunger may be
elongated and the rod dispensed with.
The operation of an apparatus provided with a plunger having either one or two
such ends and having the thrust at either one or both ends of the cylinder will by
the inclined surface or surfaces in contact with the liquid in the cylinder cause that
liquid to be more easily and more effectually thrust by the plunger.
The point whether it be on one or both or all sides of the plunger will be found to
conduce to this end, and to be more effectual than when as at present the end or ends
are made blunt or at a right angle or right angles with the sides of the cylinder, and
the period during which the fluid may be thrust out of the opening to the outlet
valve or valves or drawn through the inlet valves for the supply of the return stroke
is prolonged.
The inlet and outlet passages may also be provided on more than one side so as to
give better access and egress to the cylinder.
In order to prevent the liquid from wedging at or near the point of contact between
the plunger and the side of the cylinder a step may be formed on the plunger such
step to be at a suitable angle with the parallel sides of the plunger.
The plunger may be connected directly to a working lever without the intervention
of a separate rod or rods.

Improvements in Pumping Apparatus.
We JOSEPH ARMYTAGE WADE, Timber Merchant and Manufacturer of Pumps and
JOHN CHERRY, Mechanical Engineer, both of Hornsea in the East Riding of the
County of York 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 relates to pumping apparatus of the plunger type and adapted to
be worked by hand, steam or other power. The objects of the present improvements

page_text: are to produce a pump combining simplicity, economy and strength with ease and
efficiency in working.
In carrying out our invention as a pumping apparatus for raising or forcing liquids
or for other. hydraulic purpose we employ a plunger having one or both ends of
pointed or partially pointed or of wedge form, either single or multi-sided and
working within a cylinder furnished with suitable inlet and outlet apertures, and
controlled by suitable valves.
The plunger, ram or piston will be provided with either one or more such ends,
according to the object for which it is intended.
In the case of a plunger with two such ends, it may be connected by a rod with the
motive power for operating it.
When formed with such single pointed or wedge shaped end, the plunger may be
elongated and the rod dispensed with.
The operation of an apparatus provided with a plunger having either one or two
such ends and having the thrust at either one or both ends of the cylinder will by
the inclined surface or surfaces in contact with the liquid in the cylinder cause that
liquid to be more easily and more effectually thrust by the plunger.
The point whether it be on one or both or all sides of the plunger will be found
to conduce to this end, and to be more effectual than when, as at present, the end or
ends are made blunt or at a right angle or right angles with the sides of the cylinder,
and the period during which the fluid may be thrust out of the opening to the outlet
valve or valves or drawn through the inlet valves for the supply of the return stroke
is prolonged.
The inlet and outlet passages may be provided on more than one side, so as to give
better access and egress to the cylinder.
In order to prevent the liquid from wedging at or near the point of contact
between the plunger and the side of the cylinder a step may be formed on the
plunger such step to be at a suitable angle with the parallel sides of the plunger.
The plunger may be connected directly to a working lever without the inter-
vention of a separate rod or rods.
DESCRIPTION OF THE DRAWINGS.
Fig. 1. is an external view,
Fig. 2. is a vertical longitudinal section, and
Fig. 3. is a transverse section, respectively of the pump.
Fig. 4. is a part of the sectional end elevation of the same.
Fig. 5. is a plan view of outlet and valve boxes.
Fig. 6. is a plan view of the foundation plate.
Fig. 7. shows a modification in the arrangement of the pump chiefly designed for
use by hand power.
Fig. 8. is another modification.
Fig. 9. is a detail in sectional view showing the arrangements of the valves and
parts adjacent.
Fig. 10. shows a vertical sectional viow of another modification.
In Fig. 3. the plunger is supposed to be removed.
a is the foundation plate, & the pump case or cylinder, cc the inlet valve boxes,
dd the outlet valve boxes, e the outlet, the engine cylinder,
the inlet, ½ the
plunger ram or piston, i tho plunger or piston rod, & the outlet valve box covers.
In Fig. 7. the plunger is connected at its head * to the lover which may be
worked by hand. This lover has its fulcrum at m² by being jointed to the link m
which again is jointed at m² to a projection a¹ from the frame a.
In Fig. 8. the brackets a a serve as the base or foundation for the two cylinders bb,
two inlet valves cc the outlet valves d, d, controlling passages to the outlet e. The
inlet valves c control passages leading to the joint inlet g. hh are rams pistons on
plungers working in the cylinders b. is a slide bar for receiving a crank pin.

lines indicate the extreme position reached by the ram in the one direction
and the dotted lines the extreme position reached in the opposite direction.
In operation with apparatus of the character hereinbefore described and shewn
in the drawings it will be understood that the inclined surface or surfaces of the
ram, piston or plunger bin contact with the liquid will cause that liquid to be more
readily and effectually drawn or thrust by the piston ram or plunger and the point
whether on one both or all sides of the plunger will bo found to conduce to the same
end. indicates a stop or part of the face of the piston ram or plunger. hat or
near the point of contact between the inclination on the face of the plunger and
the side of the cylinder adapted to prevent wedging of the liquid at that point.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In pumps having a plunger, ram or piston forming the said plunger ram or
piston with a wedge pointed or tapering end or face or wedge pointed or tapering
ends or faces in contact with the liquid in the cylinder or cylinders so as to cause
the liquid to be more easily and effectually displaced by the said plunger, ram or
piston or plungers, rams or pistons.
2. The combination and arrangement of parts of pumping apparatus set forth
with referenco to Figs. 1, 2, 3, 4, 5, and 6 substantially as and for the purpose
hereinbefore set forth.
3. The combination and arrangement of parts for pumping apparatus substantially
as and for the purposes set forth, with reference to Fig. 7.
4. The combination and arrangement of parts for pumping apparatus substantially
as and for the purposes set forth, with reference to Figs. 8. and 9.
5. The arrangement and combination in pumping apparatus of a plunger ram or
piston or plungers rams or pistons each having an inclined, wedged pointed, or
tapering end with suitable piston inlet and outlet valve or valves and enlarged
passage o, o. or passages round the plunger ram or piston so as to facilitate ingress
and egress of liquid substantially as set forth with reference to Fig. 10.
6. In apparatus for pumping liquids the general arrangement and combination
of parts cooperating substantially as and for the purpose hereinbefore set forth.
