PROVISIONAL SPECIFICATION.
Apparatus for the Production of Disinfectant, Antiseptic,
Air-moistening, and other Sprays.
I, ALFRED RENÉ UPWARD of 150 Holland Road Kensington London Electrical
Engineer do hereby declare the nature of this invention to be as follows:-
:-
This invention has for its object the application of the stored power furnished by
gas liquefied under pressure & stored in a suitable vessel to produce the necessary
gaseous blast for the production of sprays: & also when required utilising the stored
gaseous power itself to actuate the outlet valve on the vessel in which it is stored as
well as supplying the gaseous blast required so arranged as to constitute a self acting
machine producing sprays at any desired & predetermined intervals of time & working
for considerable periods say several months without attention. In the latter above
stated application the store vessel containing the liquefied gas may be fitted with two
valves. One of these valves is of small dimensions & of noncorrodible metal &
capable of fine & exact adjustment so as to allow of the passage of a minute but con-
tinuous flow or discharge of gas from the store vessel. This minute but continuous
discharge of gaseous flow issuing from & controlled by this valve is utilized to actuate
& control the second valve on the store vessel the outlet from which second valve is
connected by a tube to any known form of spray nozzle, the feed pipe of which nozzle
is immersed in the liquid which is to form the sprays. A convenient method of
actuating the second valve above mentioned by the continuous flow or gaseous
discharge from the finely adjustable valve is to cause the minute gaseous flow from
the latter to enter a flexible chamber or bellows placed between discs or bellows
boards which discs or bellows boards by means of springs keep the flexible chamber
or bellows normally collapsed. The slow gaseous discharge from the finely adjustable
valve entering the flexible chamber or bellows causes it to expand with considerable
force & a spring pressed lever controlling the second valve is actuated by this motion
by means of the discs or bellows boards which enclose the flexible chamber or bellows :
the flexible chamber or bellows is provided with a small discharge passage which the
flexible chamber or bellows opens by its own motion when nearly full thus allowing
the accumulated gas within it (which caused its expanding motion) to escape more
rapidly than it is entering by the minute gaseous flow from the finely adjustable valve
the flexible chamber or bellows thus slowly collapsing by virtue of the springs which
keep it normally collapsed and in its contracting motion allowing the second valve
which valve furnishes the blast to the spray nozzle to slowly close. The flexible
chamber or bellows in its contracting motion also closes its own discharge passage so
that the continuous flow from the finely adjustable valve again begins to cause it to
slowly expand. This round of mechanical motions recurring in order until the store
of power is exhausted or until the machine is put out of use by entirely closing the
finely adjustable issue valve. It will be readily seen that the interval of time or
period between each spray thrown from this self acting spray producing machine is
governed by the time occupied in the inflation of the flexible chamber or bellows
which in turn is primarily determined by the particular setting of the finely adjustable
issue valve the minute gaseous flow from which enters & actuates the flexible chamber
or bellows thus the more widely the finely adjustable issue valve is opened the more
frequent will be the round of mechanical notions & a greater number of sprays will
be produced in a given period or in other words the shorter will be the interval of
time between each spray. When the spray producing machine is not required to be
self acting (as regards its functioning at any required & predetermined intervals by
its own self actuated mechanism) it simply being wished to cause it to function when

page_text: touched by hand the store vessel containing the liquefied gas is fitted with one
discharge valve to be opened by hand the outlet of which valve as before being con-
nected by a tube to the spray nozzle. The spindle of this valve may be attached to a
spring which keeps it normally closed so as to prevent the machine being accidentally
left continuously in action. This valve is also provided with a stop pin which
prevents it being opened too widely or screwed down too tightly. A dash pot or
water brake may also be attached to this valve so that when opened and left it closes
slowly in say one quarter of a minute or five seconds by virtue of the self closing
spring above described working against the dashpot or waterbrake. When wished
the lever of this valve is mechanically attached to the door or entrance of the privy or
place in which it is desired to diffuse the spray so that the ordinary motion of the door
or entrance opens the valve the valve slowly closing by virtue of the spring above
described its action on it being retarded by the dashpot or waterbrake so as to keep
tne spray in operation for a sufficient interval of time to be efficient. Clockwork or
clockwork closing the circuit of an electro magnet or water power or mercury or
other liquid falling "drop by drop" from an adjustable aperture fed from a small
tank or reservoir may be utilized to periodically open & close the valve on the store
vessel containing the liquefied gas, the combination constituting a selfacting machine
producing sprays at any desired predetermined intervals & working continuously
without attention. Any convenient mechanical chemical or other source of power
may be utilized to open & close the discharge valve on the store vessel but I prefer
to use the simple method of actuating any intermittency mechanism by the minute
but continuous & adjustable flow or gaseous discharge from the store vessel itself the
minute gaseous discharge being controlled by the finely adjustable issue valve as
described. Since the gaseous pressure within the store vessel containing the liquefied
gas is enormously greater than under ordinary conditions is necessary to produce the
sprays, economy in the use of this stored power may be effected by using any con-
venient form of "transformer" & intermittency mechanism as described above
combined the function of the "transformer" being to utilize the minute but high
pressure current of gas issuing from the finely adjustable valve to create a blast or
gaseous discharge (necessary to actuate the spray) of much greater volume but at
considerably reduced pressure. The tank or reservoir containing the liquid to be
diffused in the form of sprays may be of glass so that the amount of liquid it contains
is readily observable. When the form of spray nozzle used is such that it requires
the tank or reservoir to be closed & air tight the tank or reservoir may be provided
with two apertures or open necks into one of which is fitted airtight the spray
nozzle & into the other a safety valve. This valve relieves the tank or reservoir of
any undue gaseous pressure & at the same time forms a convenient method of
supplying fresh liquid to the tank or reservoir without removing the spray nozzle:
to adapt itself to this use the outlet of the safety valve terminates in a small funnel :
when it is wished to pass more liquid into the tank or reservoir the valve is lifted
from its seat against the spring which keeps it normally closed & the fresh supply of
liquid is poured in through the funnel. This having been done the valve is freed &
once more makes the tank or reservoir airtight. A "reducing valve or pressure
regulator may be fitted to the store vessel containing the liquefied gas & used in
combination with the herein described apparatus & applications where the increased
cost of the spray producing machines is not of moment. When the " reducing
or pressure regulator is used to facilitate the manipulation of the high
pressure within the store vessel no safety valve will be required on the tank or
reservoir. Any form of spray nozzle may be used with the apparatus herein
described. Spray nozzles being articles of commerce require no further description.

Apparatus for the Production of Disinfectant, Antiseptic,
Air-moistening, and other Sprays.
I, ALFRED RENÉ UPWARD, of 150 Holland Road, Kensington, W., in the County
of Middlesex, Electrical Engineer, do hereby declare the nature of my 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 the application of the stored power furnished by
gas liquefied under pressure, and stored in a suitable vessel to produce the necessary
gaseous blast for the production of sprays; and also when required utilising the
stored gaseous power itself to actuate the outlet valve on the vessel in which it is
stored as well as supplying the gaseous blast required, so arranged as to constitute
a self-acting machine producing sprays at any desired and predetermined intervals
of time, and working for considerable periods, say several months, without attention.
And in order that my invention may be the better understood, I now proceed to
describe the same in relation to the drawings hereto annexed, and to the figures and
letters marked thereon.
Figure 1 is a part sectional elevation of one form of my apparatus, in which an
intermediate collapsible chamber as described in detail in Specification No. 992488
granted to me is utilised, to operate an issue gas valve from the gas reservoir.
Figure 2 shows an arrangement in which a hand actuated gas issue valve is
controlled for gradual closing by a dash-pot.
Figure 3 shows the gas issue valve operated by an opening door or object, and
controlled for gradual closing by a dash-pot.
Figure 4 shows the gas issue valve operated and controlled by a drop by drop
cataract apparatus as described in detail and patented to me under No. 224889 but
operating a spring recoil gas issue valve.
Figure 5 shows an electrical device, operated by the elastic collapsible chamber as
in Figure 1, and controlling the opening of a gas issuo valve from the storage chamber.
Figure 6 shows a sectional elevation of an air tight chamber, discharging a constant
liquid spray by gas pressure, and fitted with a safety valve and filling nozzle.
Like letters refer to similar parts in the various figures.
In the latter above stated application, where the store vessel A actuates both the
spray and the controlling intermittent mechanism, the store vessel containing the
liquefied gas may be fitted with two valves B and C. One of these valves B is of
small dimensions, and of non-corrodible metal, and capable of fine and exact adjust-
ment, so as to allow of the passage of a minute but continuous flow or discharge of
gas from the store vessel. This minute but continuous discharge or gaseous flow,
issuing from, and controlled by, this valve B, is utilized to actuate and control (by a
collapsible chamber D, and sudden valve release mechanism, Figure 1, as already
patented to me under No. 992488) the second valve C on the store vessel, the outlet
from which second valve is connected by a tube to any known form of spray
nozzle E, the feed pipe of which nozzle is immersed in the liquid which is to form
the sprays.
A convenient method of actuating the second valve C³ above mentioned by the
continuous flow of a gaseous discharge from the finely adjustable valve B is to
cause the minute gaseous flow from the latter to enter a flexible chamber or
bellows D placed between discs or bellows boards which discs or boards by means
of springs keep the flexible chamber or bellows normally collapsed.
The slow gaseous discharge from the finely adjustable valve entering the flexible
chamber or bellows causes it to expand with considerable force and a spring pressed
lever F controlling the second valve (is actuated by this motion by means of the discs or
bellows boards which enclose the flexible chamber or bellows. The flexible chamber
or bellows is provided with a small discharge passage G which the flexible chamber
or bellows opens by its own motion when nearly full, thus allowing the accumulated gas

page_text: within it (which caused its expanding motion) to escape more rapidly than it is
entering by the minute gaseous flow from the finely adjustable valve B, the flexible
chamber or bellows thus slowly collapsing by virtue of the springs H, which keep it
normally collapsed, and in its contracting motion allowing the second valve C, which
now furnishes the blast to the spray nozzle, to slowly close. This is effected as
follows: A pin d is provided on the spindle D' of the collapsible chamber. In its
upstroke the pin passes the jointed finger of the spring pressed valve lever F. On
its down stroke the said pin d pulls down the lever F, opening the gas issue valve C,
until the pin d passes the end of the said valve lever F, upon which the spiral recoil
spring on the valve spindle, once more closes the gas issue valve C. The flexible
chamber or bellows in its contracting motion also closes its own discharge passage
and valve G, so that the continuous flow from the finely adjustable valve B again
begins to cause it to slowly expand. This round of mechanical motions recurs in
order until the store of power is exhausted, or until the machine is put out of use
by entirely closing the finely adjustable issue valve B. It will be readily seen that
the interval of time or period between each spray thrown from this self-acting spray
producing machine is governed by the time occupied in the inflation of the Hexible
chamber or bellows D which in turn is primarily determined by the particular
setting of the finely adjustable issue valve B the minute gaseous flow from which enters
and actuates the flexible chamber or bellows thus the more widely the finely adjustable
issue valve is opened the more frequent will be the round of mechanical motions and a
greater number of sprays will be produced in a given period; or in other words, the
shorter will be the interval of time between each spray.
When the spray producing machine is not required to be self acting (as regards
its functioning at any required and predetermined intervals by it own self-actuated
mechanism) it simply being wished to cause it to function when touched by hand,
the store vessel containing the liquefied gas is fitted with one discharge valve C
Figure 2 to he opened by hand, the outlet of which valve as before being connected
by a tube to the spray nozzle E. The spindle of this valve may be attached to a
spring which keeps it normally closed so as to prevent the machine being
accidentally left continuously in action. This valve is also provided with a stop pin
which prevents it being opened too widely or screwed down too tightly. A dashpot
or water brake J may also be attached to the valve so that when opened and left, it
close slowly in say one quarter of a minute or five seconds by virtue of the self-
closing spring above described, working against this dashpot or water brake.
When wished, the lever of this valve is mechanically attached to the door K Figure 3
or entrance of the privy or place in which it is desired to diffuse the spray, so that
the ordinary motion of the door or entrance opens the valve, the valve slowly closing
by virtue of the springs above described, its action being retarded by the dash-pot
or water brake J, so as to keep the spray in operation for a sufficient interval of time
to be efficient. Clockwork direct, or the closing of the circuit of an electro magnet
(Figure 5) by a reciprocating appliance, as illustrated in Figure 1; or water power,
or mercury, or other liquid falling drop by drop from an adjustable aperture M
(Figure 4), fed from a small tank or reservoir through a cataract as described in detail
and already patented to me under No. 224880 may be utilized, so as to periodically
open and close the valve C, on the store vessel, containing the liquefied gas, the com-
bination constituting a self-acting machine, producing sprays at any desired and
predetermined intervals, and working continuously without attention.
The closing of an electrical circuit may be effected as shown in Figure 5. The
spindle I of a reciprocating mechanism as described in relation to Figure 1 is provided
with two pins dd, which strike a pivotted lever S, held by a spring T, so that the
lever is pulled forcibly over dead centre, once it has passed that point. When in
the position as shown, an electrical circuit is closed through the electro magnets L by
a spring tongue from the binding screw t resting on the said lever S. The movement
of the armature Y is utilized to open the gas issue valve y.
Any convenient mechanical chemical, or other source of power may be utilized to
open and close the discharge valve on the store vessel. But I prefer to use the

page_text: simple method of actuating any intermittent mechanism by the minute but continuous
and adjustable flow or gaseous discharge from the store vessel itself, as described in
relation to Figure 1, the minute gaseous discharge being controlled by the finely
adjustable issue valve B as described.
Since the gaseous pressure within the store vessel containing the liquefied gas is
enormously greater than under ordinary conditions is necessary to produce the sprays,
economy in the use of this stored power may be effected by using any known and
convenient form of reducing valve, and intermittent mechanism, (as described above
in relation to Figure 1) combined; the function of the reducing valve or "transformer
being to utilize the minute but high pressure current of gas issuing from the finely
adjustable valve to create a blast or gaseous discharge (necessary to actuate the spray)
of much greater volume but at considerably reduced pressure.
39
The tank, or reservoir N containing the liquid to be diffused in the form of
sprays may be of glass so that the amount of liquid it contains is readily observable.
When the form of spray nozzle used is such that it requires the tank or reservoir
to be closed and air-tight, as in Figure 6 the tank or reservoir N may be provided
with two apertures or open necks P P into one of which is fitted air tight the spray
nozzle E and into the other a safety valve Q. This valve relieves the tank or reservoir
of any undue gaseous pressure and at the same time forms a convenient method of
supplying fresh liquid to the tank or reservoir without removing the spray nozzle: to
adapt itself to this use the outlet of the safety valve terminates in a small funnel R:
when it is wished to pass more liquid into the tank or reservoir the valve is lifted
from its seat against the spring which keeps it normally closed and the first supply of
liquid is poured in through the funnel; this having been done the valve is freed and
once more makes the tank or reservoir air-tight.
A "reducing valve" or pressure regulator may be fitted to the store vessel con-
taining the liquefied gas and used in combination with the herein described apparatus
and applications when the increased cost of the spray producing machine is not of
moment. When the "reducing-valve" or pressure regulator is used so facilitate the
manipulation of the high pressure within the store vessel no safety valve will be
required on the tank or reservoir.
Any form of spray nozzle may be used with the apparatus herein described.
Spray nozzles being articles of commerce require no further description.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
