PROVISIONAL SPECIFICATION.
A Machine for Throwing a Liquid Spray for the Purpose of Cleaning,
Cleansing, Whitewashing or Colour Washing, or Throwing a
Liquid in a Fine Spray for Destroying Blight and Insects.
FRANCIS ASHBY WALLIS Eype House Basingstoke Engineer, doth hereby declare
the nature of this invention to be as follows:-
1 construct a machine upon wheels or otherwise which is fitted with any known
kind of high pressure force pump, which can be worked by hand or foot or from the
main travelling wheel or wheels upon which the machine is carried. The suction
pipe of this pump is placed in a bucket, tub or suitable tank containing the liquid,
white-wash or colour-wash to be used. I attach a flexible or jointed or fixed pipe to
the delivery of the force pump, to which is attached by suitable means a nozzle or
nozzles of suitable shape, with outlets sufficiently small so that I am able to maintain
a considerable pressure when the force pump and jets are working, by this means
the liquid, whitewash, or colourwash is thrown in drops or fine spray.
Also I make a machine mounted on wheels or otherwise, which is fitted with an air
pump which can be worked by hand or foot or from the main travelling wheel or
wheels upon which the machine is carried. The delivery pipe of the air pump is
attached to a convenient chamber or tank, into which is placed the liquid or white-
wash or colour-wash. A flexible or jointed or fixed pipe fitted with one or more
suitable nozzles, is attached to the base of the chamber or tank, the outlet of the
nozzle or nozzles is sufficiently small so that I am able to maintain a considerable
pressure when the air pump and nozzles are working, by this means the liquid, white-
wash or colour-wash is thrown in drops or fine spray.
Also I make a machine mounted on wheels or otherwise which is fitted with a
steam boiler. A flexible or jointed or fixed pipe is attached to the steam outlet of
the boiler and one or more suitable shaped nozzles are attached to the pipe so that a
jet or number of jets of steam are procured. Into the steam jet or jets either in
front of the nozzle or nozzles or into the steam pipe, I admit by means of a suitable
tank and piping the liquid, whitewash or colourwash, by this means the liquid, white-
wash or colour-wash is thrown in drops or fine spray.
Also I make a machine for whitewashing and colourwashing, mounted on wheels or
otherwise, which is fitted with a fan, blower, bellows or air pump which may be
worked by foot, hand or otherwise. A flexible or jointed or fixed pipe is attached to
the mouth of the fan, blower, bellows or air pump and one or more suitable nozzles
are attached to the pipe so that a jet or a number of jets of air are produced. Into
the air jet or jets either in front of the nozzle or nozzles, or into the air pipe, I admit
by means of a suitable tank and piping the white-wash or colour-wash, by this means
the white-wash or colour-wash is thrown in drops or fine spray.

COMPLETE SPECIFICATION.
A Machine for Throwing a Liquid Spray for the Purpose of Cleaning,
Cleansing, Whitewashing or Colour Washing, or Throwing a
Liquid in a Fine Spray for Destroying Blight and Insects.
I, FRANCIS ASHBY WALLIS, Eype House, Basingstoke, Engineer, 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 :-
I construct a machine upon wheels or otherwise which is fitted with any known

page_text: kind of high pressure force pump, which can be worked by hand or foot or from the
main travelling wheel or wheels upon which the machine is carried.
The suction pipe of this pump is placed in a bucket, tub or suitable tank containing
the liquid, whitewash or colour wash to be used. I attach a flexible or jointed or
fixed pipe to the delivery of the force pump, to which is attached by suitable means
a nozzle or nozzles of suitable shape, with outlets sufficiently small so that I am able
to maintain a considerable pressure when the force pump and jets are working, by
this means the liquid whitewash or colourwash is thrown in drops or fine spray.
Fig. 1 of the accompanying drawings is a longitudinal section and Fig. 2 is an end
view of a portable machine according to my invention for white washing and such
like purposes, this machine being arranged to be worked by hand. L is a hand lever
by which reciprocating motion is given to the plunger P of a force pump which
draws the liquid from the receptacle R and delivers it to an air vessel A and to a
flexible pipe T provided with a suitable nozzle and deflector N to break up the
stream of liquid into spray. The suction pipe S is attached to the plunger P so
that it moves to and fro with it agitating the contents of the receptacle R. The
mouth of the pipe S may have a grating of wire or other fabric to keep back solid
pieces.
Fig. 3 is a vertical section of a modified form of machine mounted as on a wheel
barrow so that it can be readily moved from place to place. In this figure the parts
corresponding to those in Figs. 1 and 2 are marked by similar letters. The upper
part S of the suction pipe is made flexible so as to allow of the pipe being moved to
and fro as an agitator by a link B connecting the pipe S to the lever L. I prefer to
fix several perforated discs D on the stem of the pump bucket so that as they move
up and down they keep the liquid in agitation.
Fig. 4 is a side view partly in section, Fig. 5 is an end view, and Fig. 6 is a
plan of one form of nozzle and guard suitable for delivering the white or colour
wash which is forced by my machine along the pipe T. In front of the nozzle N
I mount an oblique sided deflector F which can be turned upon its axis so as
to vary the direction and spread of the jet from N.
Beyond the deflector and mounted on the same axis is a guard G of triangular
form having at its mouth an inwardly turned lip g so as to prevent the outflow of
such of the liquid as may run along the interior surface of the guard. I also provide
a gutter so that when the guard G is turned upwards this gutter catches such
liquid as may flow down the oblique surfaces of the guard and delivers it along
with such as may flow along the flat side to a pipe K by which it is returned to the
receptacle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim in respect of machines for throwing a liquid spray for purposes such as white-
washing or the like, is :-
1. The combination of a receptacle for the liquid to be thrown, a force pump and
agitator and a nozzle and deflector, substantially as described.
2. The machine herein described with reference to Figs. 1 and 2.
3. The modified machine herein described with reference to Fig. 3.
4. The combined nozzle deflector and guard herein described with reference to
Figs. 4, 5 and 6.
