We, ROUGHSEDGE WALLWORK, Engineer, of the Firm of Henry Wallwork &
Co., of Roger Street, Manchester, in the County of Lancaster, and ARTHUR
COLLINGS WELLS, Engineer, of the Firm of A. C. Wells & Co., of 103 Midland
Road, St. Pancras, in the County of London, do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus for spraying or showering liquids for
lighting, painting and other purposes.
According to our invention we pivotally arrange in a suitable vehicular frame
or trolley an oil tank which is furnished with a centrally located internal air
pump worked by an appropriate hand lever suitably pivoted in the aforesaid frame-
or trolley. This air pump serves the double purpose of compressing the air in
the space above the level of the liquid in the tank and of charging said tank with
liquid when required. Suitable outlets are provided on the tank to permit the
compressed air and liquid to flow away through flexible hose to upright metal
pipes leading to the spraying or showering nozzle which is situated at their
upper end.
These pipes serve as a standard to elevate the said nozzle to the required height
and are made movable so that when the apparatus is out of use they can be
caused to assume a lowered position. For this purpose the aforesaid frame or
trolley may be provided with a clip which is adapted to embrace the said upright
pipes and by means of a screw, such clip can be readily loosened so as to enable
the pipes to be raised or lowered, the aforesaid flexible hose permitting of such
movement of the pipes.
When the apparatus is to be used for lighting purposes we employ in conjunc-
tion with the nozzle a detachable wick holder of special form which is adapted
to be applied to the nozzle or to the pipes contiguous thereto by means of a thumb
screw or other appropriate device. The said wick tube may have both its ends
bent upwardly one of said ends lying just below the outlet from the nozzle and
being provided with a wick, while the other end lies below the rear part of the
nozzle. The nozzle is so constructed at its rear part that by operating a suitable
valve a portion of the oil forced to the nozzle can be caused to drip from said
valve and enter the end of the wick tube that lies below the rear part of th
nozzle. The oil thus escaping from the nozzle feeds the wick tube with the
necessary amount of oil to supply its wick, which therefore serves as a pilot
light. This supply of oil is self acting and stops when the apparatus is not in
use. The nozzle may also be furnished with a detachable hood to protect it from

page_text: wind. Suitable taps may be provided for enabling a flashing of the light to be
produced so that the apparatus can be used for military or other signalling
purposes.

Improvements in or relating to Apparatus for Spraying or Showering
Liquids for Lighting, Painting, and other purposes.
We, ROUGHSEDGE WALLWORK, Engineer, of the Firm of Henry Wallwork &
Co., of Roger Street, Manchester, in the County of Lancaster, and ARTHUR
COLLINGS WELLS, Engineer, of the Firm of A. C. Wells & Co., of 103 Midland
Road, St. Pancras, in the County of London, 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:-
According to our invention we pivotally arrange in a suitable vehicular frame
or trolley, an air tight tank which is furnished with an internal air pump
worked by an appropriate hand-lever suitably pivoted in the aforesaid frame or
trolley. This air pump performs the double function of compressing the air
in the space above the level of the liquid in the tank and of charging said tank
with liquid when required. Suitable outlets are provided on the tank to permit
the compressed air and liquid to flow away through flexible hose to upright metal
pipes leading to the spraying or showering nozzle which is situated at their upper
end.
These pipes are movably mounted on the trolley and serve as a standard to
elevate the said nozzle to the required height; when the apparatus is out of use
the said pipes can be caused to assume a lowered position.
When the apparatus is to be used for lighting purposes we employ in conjunc-
tion with the spraying or showering nozzle a detachable wick holder of special
form which is adapted to be applied to the said nozzle, or to the pipes contiguous
thereto,, by means of a thumb screw or other appropriate device. The nozzle is
so constructed at its rear part that by operating a suitable valve a portion of the
oil forced to the nozzle can be caused to drip from said valve into an opening
with which the wick holder is formed and thus supply the wick holder with the
necessary amount of oil to feed its wick, so that it will serve as a pilot light. This
supply of oil is self acting and stops when the apparatus is not in use.
The nozzle may also be furnished with a detachable hood to protect it from
wind.
Suitable taps may be provided for enabling a flashing of the light to be
effected so that the apparatus can be used for military or other signalling pur-
poses.
In order that our said invention may be clearly understood and readily carried
into effect we will proceed to describe the same more fully with reference to the
accompanying drawings in which:-
Figure 1 is a side elevation of the tank and its trolley, and
Figure 2 is a central transverse section thereof.
Figure 3 is a detail view, on an enlarged scale, of the lower end of the air
pump.
Figure 4 is a plan of the cover of a detachable liquid vessel for use with the
tank as hereinafter described.

page_text: Figure 5 is an elevation of the aforesaid tank and its trolley provided with the
upright movable pipes carrying the nozzle and the pilot lamp.
Figure 6 is a detail sectional view of the aforesaid nozzle and pilot lamp drawn
on a larger scale.
Figure 7 is an elevation of a modified form of the apparatus for lighting
purposes.
Figure 8 is an elevation of the apparatus adapted for flash signalling purposes.
Figure 9 is an elevation of the nozzle as it is arranged for spraying or showering
disinfecting or other liquids on to walls, trees and other objects.
A is the air tight tank and B the framing of the trolley in which the said
tank is pivotally mounted. C is the air pump. D is the spraying or showering
nozzle and E is the pilot lamp.
Referring more particularly to Figures 1 to 4 the aforesaid air tight tank A
consists of a cylindrical vessel having at its lower end lugs A¹ A by which it
is pivotally mounted in the framing B by means of a bolt B¹. The said. framing
is mounted on wheels B* B* to permit of the apparatus being readily moved from
place to place. Arranged centrally within the tank A is the vertical air-pump C,
the barrel of which is furnished at its upper end with a cap C¹ bolted to the
cover A of the tank. The piston rode passes through a stuffing box C and
gland C³ with which this cap is provided, the outer end of the said piston rod
being pivotally connected at c to the hand lever c. This hand lever is also
pivotally connected to the framing B by means of a transverse bolt stay B³ about
which the said hand lever can be freely rocked to work the piston rod. The inner
end of the piston rod is connected to the piston, which consists of a disc having
holes therein and fitting on to the reduced end of the piston rod, where it
is held in place by a second disc or washer which is formed with radial recesses c
Between the two discs and a leather cup shaped washer & is located, sufficient
space being left between the two discs to permit of its uncovering the holes in
the disc as the piston ascends in the pump barrel and closing them again
when the piston descends. The said leather washer c' thus serves the double
purpose of a flap valve and a packing ring for the piston.
The lower end of the pump barrel is secured by a metal strap 8 from which
project depending lugs or arms carrying at their lower ends a ring co. This
ring supports springs cell which in turn support a valve 2 by which the outlet
end of the pump barrel is normally kept closed.
At the upper end of the pump barrel is an inlet opening C through which
enters the air to be compressed in the tank or the liquid with which said tank
is to be charged. A flexible pipe C5 is connected to this opening for the purpose
of enabling the liquid to be withdrawn from a pail or cther receptacle. The end
of the said pipe is preferably provided with a strainer C. A3 is a gauge for
indicating the pressure within the tank A.
Gis a pipe through which the liquid from the tank A is forced to the nozzle D
by the air pressure, the said pipe dipping into the liquid and extending almost to
the bottom of the tank. H is a pipe through which the air under pressure passes
to the said nozzle from the tank.
When the apparatus is to be charged with liquid the flexible pipe C³ is dipped
into the pail or other receptacle containing the liquid that is to be used and then
the person who is to operate the apparatus stands upon the foot plate or platform B³
with which the framing B is provided. He then grasps the handle and proceeds
to reciprocate the piston of the pump C by oscillating said handle about its
pivot B, the tank A. rocking about its pivot B during such oscillation of the
handle. At each down stroke of the piston the liquid is drawn into the space
above the piston in the pump C through the aforesaid pipe C and at the same
time the liquid that is in the space below said piston is expelled from the pump,
through the outlet valve c, into the surrounding space within the tunk. At
each upstroke of the piston the said valve cremains closed and the liquid which
has previously been drawn into the space above the piston is forced through the

page_text: openings past the cup shaped washer into the space below said piston
ready to be expelled from the pump at the next down stroke of the piston. To
indicate when the tank has been sufficiently charged with liquid we provide a
cock A through which the liquid in the tank will flow when it reaches the level
thereof. Having charged the tank with liquid to the required extent the cock A*
is closed and the pipe C is removed from the aforesaid receptacle. The user then
continues to work the pump piston as already described, but instead of now
drawing in liquid through the said pipe C, air is drawn in and compressed in
the space within the tank above the liquid it contains. The weight of the user's
body on the platform B3 will prevent the framing B from unduly shifting during
the charging operation. The aforesaid platform also serves to receive the pipes,
nozzle and other fittings required to be used with the tank, so that all the parts
can be conveniently moved from place to place by wheeling the trolley along by
its shafts B* B*.
In some cases, especially when the liquid with which the tank A is to be
charged is like paint, difficulty may be experienced in effectually emptying and
cleansing the tank thereof prior to another charge of liquid of a different nature
or of paint of another tint. In order to overcome this difficulty we sometimes
provide on the tank A (as in Figure 1) a bracket A5 to support a detachable
vessel a to contain the paint, such. vessel being secured in place by a pivoted
frame or yoke a¹ having a screw as at its upper part. By tightening the screw
until it bears firmly upon the cover a of the said vessel a, the latter is rigidly
held in place on the bracket. The frame or yoke can be readily turned down-
wardly about its pivot when the screw a³ is loosened, and thus release the vessel a.
The aforesaid cover of this vessel has two openings a as one of which (a) is
connected by a pipe a with the compressed air in the tank A and the other (a)
is provided with a pipe a descending almost to the bottom of the vessel a.
paint passes up this pipe a' to the pipe g through which it reaches the showering
nozzle as in the previous case. The pipe G in this instance (as the tank contains
only compressed air) serves as the pipe for conveying the compressed air to the
nozzle. In order to allow the aforesaid yoke to be easily turned downward about
its pivot to release the vessel a, it will be found advantageous to arrange the
aforesaid openings a' as in the position shown in Figure 4 instead of in the position
shown in Figure 1.
The
In the apparatus shewn at Figure 5 we have illustrated the trolley provided with
upright pipes G¹ and H' carrying at their upper ends the nozzle D and the pilot
lamp These pipes are held in their upright position by means of clips b b
carried by an extension piece 61 which is connected to the shafts of the trolley.
The said clips are furnished with butterfly nuts 6 6 by which they can be caused
to grip the pipes. The lower ends of said pipes are connected by flexible pipes to
the tank and therefore the pipes G₁ and H¹ can be elevated or depressed to raise
or lower the nozzle to the required extent, the said clips when tightened by their
nuts effectually gripping the said pipes and locking them in the required
position.
In Figure 7 we have shewn a modification of the apparatus which is specially
intended for flash signalling purposes. In this case the upright pipes G and H
are connected by unions J to the tank and are supported by means of a stem K
which enters a socket K¹ formed for its reception in the tank A. G is a tap on
the pipe G¹ by means of which the liquid pipe leading to the nozzle can be
momentarily closed and opened again for producing the flashing of the light.
For military purposes the upright pipes G and H can be supported in a tripod L
as illustrated in Figure 8, and the said pipes G¹ and H¹ can be concentrically
arranged one within the other. In this case the flash tap G8 is located at the
lower end of the upright pipes at a point where the flexible pipes G and H are
connected thereto.
In the arrangements shewn in Figures 5 to 8 the nozzle is provided with a
pilot lamp which is fed with oil from the nozzle as best seen in Figure 6. For

page_text: this purpose the pilot lamp is provided with a thumb screw E¹ by which it is
connected to the upright pipes G¹ H. Its front portion is formed with a bent up
end or wick tube e and its rear portion has an opening e¹ therein, such opening
being situated immediately below the rear end of the nozzle, which is furnished
with a drip valve d. This valve can be more or less opened by turning the hand
wheel d¹ so that as the oil is forced up the pipe G₁ to the nozzle, it will drip
therefrom into the opening e¹ and thereby supply the wick in the pilot lamp
with the requisite amount of oil to keep it alight. Thus each time the oil
supply to the nozzle is momentarily cut off to put out the nozzle light and turned
on again the pilot light ignites it afresh. The flashing of the light is thus
effectually obtained. M is the detachable hood with which the nozzle is provided
for the purpose of protecting the light from wind.
Figure 9 represents the nozzle arranged on a pair of concentric pipes and in
such form the said nozzle can readily be used for showering disinfecting liquid
on to a tree, wall or other object.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. Apparatus for use in spraying or showering liquids consisting in the com-
bination of an air tight tank pivotally mounted in a trolley or similar vehicle
and of an air pump having its piston rod pivotally connected to the framing of
the trolley by an oscillatory hand lever substantially as described and for the
purposes specified.
2. The combination with the aforesaid pivoted tank and its trolley of a detach-
able vessel capable of being applied to the tank substantially as described and for
