PROVISIONAL SPECIFICATION.
Improvements in and connected with Pumps.
I, JOHN JAMES STOTT of Barton House, Deansgate, Manchester, in the County
of Lancaster, Yarn Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to pumps employed for the purpose of delivering mixed
fluids, as for example mixtures of oil and water, of disinfectants or insecticides and
water and the like, and its object is to ensure the perfect mixture in definite
proportions, of the fluids.
According to my invention I place the fluid which is to be mixed with the water
for delivery by the pump, in a tank from the lower part of which there is an outlet
adjustably controlled by a suitable regulating tap. This outlet is connected with
one end of a pipe, the other end of which opens in the pump suction pipe, preferably
as near as practicable to the underside of the foot valve. With this arrangement
when the pump is put into action it will deliver a constant and uniform mixture
with the water, of the fluid from the tank, and the proportions of the mixture can
be readily controlled and determined by means of the regulating tap.
If the fluid in the tank which is to be mixed with the water consists of a mixture
the constituents of which would subside or separate when at rest, an agitator may
be contained in the tank and be operated together with the pump.
The tank may have upon its cover a locking device which when the cover is
closed will engage with the handle of the tap and fix it in any position in which it
may have been previously placed.
A pump constructed and arranged according to this invention is particularly
applicable for spraying trees and plants with insecticides and the like and for other
analogous purposes.

COMPLETE SPECIFICATION.
Improvements in and connected with Pumps.
I, JOHN JAMES STOTT, of Barton House, Deansgate, Manchester, in the County
of Lancaster, Yarn Agent, 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 pumps employed for the purpose of delivering mixed
fluids, as for example, mixtures of oil and water, of disinfectants or insecticides and
water and the like, and its object is to ensure the perfect mixture of the fluids in
definite proportions.
According to my invention the fluid which is to be mixed with the water for
delivery by the pump, is placed in a tank from the lower part of which there is an
outlet adjustably controlled by a suitable regulating tap. This outlet is connected
with one end of a pipe the other end of which opens into the pump suction pipe,

page_text: preferably as near as practicable to the underside of the foot .valve. With this
arrangement, when the pump is put into action it will deliver a constant and
uniform mixture of water and fluid from the tank, and the proportions of the
mixture can be readily controlled and determined by means of the regulating tap.
If the fluid in the tank is in itself a mixture the constituents of which would
subside or separate when at rest, an agitator or stirrer may be contained within the
tank and be operated either with the pump or separately.
The accompanying drawing reference to which is made hereinafter illustrates in
section part of the pump cylinder and suction pipe and shows the application of the
pipe from the tank.
A is the pump cylinder containing the plunger or piston B. C is the foot valve
closing the suction pipe D at its entrance into the cylinder. E is the pipe com-
municating with the tank containing the fluid which is to be mixed with the water
and delivered from the pump. This pipe E leads into the pump suction pipe
preferably close to the underside of the foot valve, and is furnished at some
convenient part of its length with a tap or valve F by means of which the quantity
of fluid passing from the tank to the pump may be controlled or regulated. If
desired the tap F may be so placed and arranged as to engage with a catch or with
a recess or projections formed upon the cover of the tank or the framing of the
apparatus and thus be held in its open or in any desired position.
The pump may be of the usual or any suitable construction and may have the
tank combined with it in any suitable casing or frame.
A pump constructed and arranged according to this invention is particularly
applicable for spraying trees and plants with insecticides and the like and for other
analogous purposes.
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 :
In a pump for delivering fluids the combination with the suction pipe of a second
auxiliary pipe constructed and arranged substantially as and for the purpose
hereinbefore described and as illustrated by the accompanying drawings.
