PROVISIONAL SPECIFICATION.
Apparatus for the Distribution of Insect-exterminating and
Weed-destroying Liquids.
I, WILLIAM FREDERIC CHARLES of Market Place, Loughborough Chemist
and Druggist do hereby declare the nature of this invention to be as follows:-
This invention has for its object an improved portable apparatus for distributing
liquids of such a nature as to destroy parasitic vermin of all kinds, on plants
foliage, flowers &c., without injuring the same, also for distributing liquids for
destroying weeds of all kinds.
The component parts of the apparatus are; a collapsible indiarubber ball having
suitable inlet, and outlet valves; the outlet valve discharging into a collapsible
indiarubber receiver, a tube from which communicates with the upper part of a
vessel containing the insect, or weed-destroying liquid. A second tube reaching
nearly to the bottom of the vessel and passing through an air-tight stopper, is
provided at its outer end with a rose of perforated metal for the more effectual
division, and distribution of the liquid.
The action of the apparatus is as follows:
The vessel containing the aforesaid liquid is held in one hand of the operator,
whose other hand grasps the collapsible indiarubber ball. By alternately com-
pressing and relaxing the pressure on the said ball, air is drawn through the inlet
valve, and forced through the outlet valve into the small indiarubber receiver, and
thence through a tube into the upper part of the vessel containing the insect or
weed destroying liquid; causing a compression of the air in the upper part of the
vessel; which pressure acting upon the surface of the liquid, causes the latter to
flow with considerable velocity through the second tube, which reaches nearly to
the bottom of the vessel, and thence through the rose on to the plants, foliage or
weeds to be treated. The force of discharge being regulated at the will of the
operator by adjusting the pressure on the collapsible-ball-air-compressor.

COMPLETE SPECIFICATION.
Apparatus for the Distribution of Insect-exterminating and
Weed-destroying Liquids.
I, WILLIAM FREDERIC CHARLES of Market Place, Loughborough Chemist
and Druggist 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 has for its object an improved portable apparatus for distributing
liquids of such a nature, and in such a manner as to destroy parasitic vermin of all
kinds which infest plants, foliage or flowers, with a minimum risk of injury to the
plants &c. themselves also for distributing liquids for destroying noxious weeds;
the apparatus being so designed, and constructed as to contain the liquid to be
distributed.
To this end the invention consists in the novel construction hereinafter described,
and claimed, whereby the said end is attained.

page_text: The invention is illustrated in the accompanying drawings.
Fig. I represents a sectional end elevation of the apparatus.
Fig. II is a sectional side elevation of the same.
Fig. III is a plan of the apparatus.
Similar letters of reference designate corresponding parts in all the figures.
A represents a closed vessel for containing the liquid to be distributed; having
an air-tight stopper B provided with a small relief-valve C, the purpose of which
will be explained hereafter.
A collapsible indiarubber ball D having an inlet-valve E, and an outlet-valve F
is connected by means of the flexible tube G, and tube H to an air-tight receiver K
which is secured to the upper surface of the liquid-containing vessel.
The top of the said air-tight receiver is formed of a sheet of thin flexible india-
rubber, which, when air is forced into the upper portion of the vessel A, assumes
the position shewn approximately by the dotted lines in Fig. I.
A short tube L is the only means by which air can pass from the receiver K to
the interior of the vessel A.
M is a rigid tube reaching to within a short distance of the bottom of the liquid-
containing vessel, and is firmly secured by an air-tight joint at N to the vessel A,
the said tube being continued exterior to the vessel A, and terminating in a
removable perforated metal sprayer, or nozzle O.
The handle P is attached to the vessel A for the purpose of conveniently
operating the apparatus.
The apparatus is actuated in the following manner :-
The air-tight stopper B is taken off, and the liquid to be distributed is
introduced into the vessel A. The stopper B is then replaced. The operator
holding the apparatus by the handle P with one hand, grasps the indiarubber
ball D with the other hand, with which he alternately compresses, and relaxes the
pressure upon the said elastic ball. By this means air is drawn in through the
inlet-valve E, and forced through the outlet valve, and thence through the tubes G,
and H into the receiver K, thence through the tube L into the interior of the
vessel A. The air being thus compressed into the upper portion of the said vessel,
acts upon the surface of the liquid contained in the vessel in such a manner as to
eject the liquid rapidly through the tube M, and nozzle O, thence on to the plants,
foliage &c. to be treated, the spray being directed at the will of the operator by
means of the handle P.
The object of the thin elastic cover of the receiver K is as follows.
Air being forced into the said receiver inflates the elastic cover until it occupies
the position approximately denoted by the dotted lines. The operator may allow
the indiarubber ball D to become inoperative, while the liquid will still be ejected
from the nozzle O by reason of the compression of the air in the receiver K, and
vessel A caused by the energy given out by the elastic cover in its effort to recover
its original flat position. In case the operator should wish to discontinue the aforesaid
automatic spraying-action due to the elastic receiver, he presses down the small
valve C, which has been kept closed by the compression of the air in the vessel A,
thus relieving the air pressure in the said vessel, and causing the liquid jet
immediately to cease.
Having now particularly described, and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is;
A portable closed vessel, having air-tight joints where required; for the purpose
of containing insect, or weed destroying liquids, and forming at the same time a
reservoir for compressed air, having attached to itself a collapsible ball air-
compressor, an elastic receiver for the purpose of ensuring a continuous spray, and
also continuing the ejection of the liquid for some seconds after the collapsible ball
has ceased to be operated. A suitable relief valve for stopping the spray at the 5

page_text: will of the operator, and a delivery tube reaching nearly to the bottom of the
aforesaid vessel, and terminating at its outer end in a suitable nozzle or sprayer,
substantially as, and for the purpose herein described.
