Improved Pump.
1, WALTER WHEELER of Railway Foundry, Langley Green, in the County
of Worcester Ironfounder, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a lifting and forcing pump by gearing
two racks with a pinion fixed to a metal spindle, and attaching buckets to the said
racks, and working same within suitable cylinders all enclosed in one chamber, and
working in such method as may be found most suitable.
The said racks when geared with the pinion are held in gear by means of pins
attached to the chamber and covered with rollers which move round by the motion
of the racks.
The plungers are arranged to receive valves, and similar valves are arranged in
another chamber bolted immediately under the main chamber aforesaid, such
valves acting reciprocally with the motion of the plungers and allowing the ingress
or egress of the fluid used as the case may be.
The upper part of the main chamber is open and has a faced flange to attach
delivery pipe thereto.
An aperture is left in the main chamber for the purpose of fitting the said
various parts into position, and this is finally covered with a plate of suitable
shape. The axis of the said pinion passes through this plate which is formed
into what is generally known as a stuffing box for that purpose. The other end
of the said axis works in a bearing provided for it inside the main chamber,
therefore by means of this invention one stuffing box alone is necessary for the
pinion axis.
By partially rotating this axis by means of a handle or crank or the like the
pinion raises one and lowers the other rack, and consequently the plungers are
similarly moved up and down in the cylinders, and alternately draw and discharge
the fluid employed.
If desired plungers may be attached to each end of the racks, and so employ
four cylinders instead of two.
My invention is capable of various modes of application without departing
from the principle thereof.

Improved Pump.
1, WALTER WHEELER, of Railway Foundry, Langley Green, in the County
of Worcester, Ironfounder, do hereby declare the nature of this invention and
in what manner the same is to be perforined, to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to provide a lifting and forcing pump by gearing
two racks with a pinion fixed to a metal spindle, and attaching buckets to the
said racks, and working same within suitable cylinders all enclosed in one chamber,
and working in such method as may be found most suitable.

page_text: The said racks when geared with the pinion are held in gear by means of rollers
attached to the chamber hy bolts projecting therefrom.
The buckets are arranged to receive valves, and valves are also arranged in
another chamber bolted immediately under the main chamber, all such valves
acting reciprocally with the motion of the plungers and allowing the ingress or
egress of the fluid used.
The upper part of the main chamber is arranged to receive an outlet pipe,
and the lower part of the said lower chamber is arranged to receive an inlet pipe.
An aperture is left in the main chamber for the purpose of fitting the said
various parts into position, and this is finally covered with a plate of suitable
shape.
The spindle of the said pinion passes through this plate which is formed into
what is generally known as a stuffing box for that purpose. The other end of
the said spindle works in a bearing provided for it inside the main chamber,
therefore by means of this invention one stuffing box ouly is necessary for the
pinion spindle:
By partially rotating this spindle by means of a handle or crank and the like,
the pinion raises one and lowers the other rack, and consequently the buckets are
similarly moved up and down in the cylinders and alternately draw and discharge
the fluid employed.
My invention will be more clearly understood by reference to the accompanying
drawings.
Fig. 1. is a front elevation, partially in section, of the invention, with the
spindle e and pinion in proper position within the main chamber a, and with the
racks d geared with the pinion and maintained in that condition by the rollers m
attached to the bolts . A sectional view of a portion of one of the racks is
shewn at d².
The lower portions d³ of the racks are constructed circular in shape, and within
and over same leather "buckets "e are arranged, and Hanged metal rings fare
placed in the positions shewn, with the valves h, the whole being secured with
screws g. Immediately below the cylinders a² the lower chamber is fixed, and
contains the valve seats j. and the valves k. The valve seats have orifices so that
the fluid employed may pass through same in the direction indicated by the arrow
heads during the working of the pump.
As the bucket valves are raised as the plungers descend, so the fluid
passes through the interior of the said flanged ring fas shewn by the arrow heads
indicated in that portion of the figure.
Figure 2. is a vertical section through the centre of the pump, shewing the
plate o and the stuffing box p attached to same.
Figure 3. is a front elevation of the pump complete with a levery keyed or
fixed by any like means to the spindle or spindle c. By depressing and then raising
this lever by any convenient means the pump is set in operation.
-
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In pumps the combination of buckets working upon the rack and pinion
principle in an enclosed chamber containing cylinders substantially as herein
described and set forth.
2. The arrangement of racks and pinion within the said chamber with only one
stuffing box for the spindle of the said pinion as hereinbefore described.
