Improvements in Deodorizers.
I, GEORGE CROYDON MARKS, of "Thornholm" Stonebridge Park, in the
County of Middlesex, Consulting Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention has reference to improvements connected with deodorizing
apparatus for use in connection with lavatories, sick rooms, public buildings,
vessels, dwelling houses, and offices, and arranged in such a manner as to be capable
of producing a spray or vapour of disinfecting fluid or deodorizing fluid by the
opening and closing of the door. I am also enabled to utilize my apparatus to
ensure that the door shall be closed automatically after the spray has been produced,
or after the handle has been released.
In carrying my invention into effect I construct my spray producing apparatus
and door closing check combined in one manner by producing a cylinder, ball or
collapsible vessel or chamber which I attach to the door or frame and I arrange
that a bar or lever which is in contact with the door or frame shall by means of a
curved or inclined wedge or cam like path, force down a rod, pin or the like
so as to collapse the ball or vessel, or so as to compress a piston within a
cylinder, and thus to force out the air from within the vessel or cylinder in such a
manner as to suck up the fluid from within a chamber placed conveniently near to
it and then to eject the raised portion of fluid through an injector like nozzle in
the form of spray into the apartment. The operation of compressing and ejecting
being performed by the act of opening and closing the door.
I place my fluid chamber beneath or near my compression cylinder or vessel;
and I lead a tube from the fluid chamber to the injector branch or nozzle so that
the spray may be formed by the issuing current of air from the delivery port of
the cylinder or vessel.
When providing for a door closing device upon my apparatus, I place a spring
in combination with my cylinder piston or operating rod or lever which always
tends to keep the door closed, or I place an ordinary spiral spring about the
axles of my lever pin which by its torsional effect will serve the same purpose.
To prevent the slamming of the door I may arrange that the air within my
compression chamber or within my cylinder shall act as a baffle stop; or I may
provide a cataract arrangement of air escape within a separate portion of the
cylinder or within a separate cylinder or chamber of my combination apparatus.
1 may place my cylinder and injecting or spray producing apparatus upon the
door frame or upon the door itself allowing the operating rod, piston, cam or
lever to be placed either upon the door or upon the frame as may be desired
for any particular requirement.
I sometimes surround my compression cylinder with a chamber which I use as
a spring box or which I may use as the fluid chamber when making a compact
apparatus.
I prefer to place rollers upon my moving contact bars so as to minimise friction
and to obviate noise.
I do not limit the application of my improved spray producing apparatus for
fitting to doors which require to have closing devices attached in combination
but 1 employ the improvements either with or without the door closing
"

page_text: connections in the manner herein before described, and I sometimes provide dis-
connecting devices upon my apparatus for allowing one to work without the
other when so desired.
I employ any suitable disinfectant or deodorizing agent in my chamber from
which the spray is produced.

1, GEORGE CROYDON MARKS, of "Thornholm" Stonebridge Park, in the
County of Middlesex, Consulting 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 :-
My invention has reference to improvements connected with deodorizing
apparatus for use in connection with lavatories, sick rooms, public buildings,
vessels, dwelling houses, and offices, and arranged in such a manner as to be capable
of producing a spray or vapour of disinfecting fluid or deodorizing fluid by the
opening and closing of the door. I am also enabled to utilize my apparatus to
ensure that the door shall be closed automatically after the spray has been
produced, or after the handle has been released.
In the accompanying sheet of explanatory drawings
Figure 1 is a sectional elevation of one form of my apparatus, and
Figure 2 is a plan of the same.
Figures 3 and 4 are part sectional elevation of alternative forms of my air
expelling plungers.
Figure 5 is a sectional elevation showing my apparatus attached to a door frame
and in position for producing a spray.
Figure 6 is a sectional elevation of a modified form of apparatus and
Figure 7 is a plan of the same, while
Figures 8 and 9 are detailed views of the fittings I sometimes employ ; and
Figures 10 and 11 respectively detail front and side sectional elevations of the
piston employed.
In carrying my invention into effect I construct my spray producing apparatus
and door closing check combined in one manner by producing a cylinder A, bali A¹
or collapsible vessel or chamber A2 which I attach to the door or frame and
I arrange that a bar or lever B which is in contact with the door C or frame shall
by means of a curved or inclined wedge or cam like path or paths D, force down a
rod, pin, plate plunger or the like E so as to collapse the ball A¹ or vessel A³,
or so as to compress a piston F within a cylinder H and thus to force out the air
from within the ball vessel or cylinder, in such a manner as to suck up or expel
the fluid from within a chamber E' placed conveniently near to it and then to eject
the raised portion of fluid through an injector like nozzle F¹ in the form of spray
into the room, hall or apartment. The operation of compressing and ejecting being
performed by the act of opening and closing the door.
I place my fluid chamber E¹ preferably beneath or near my compression
chamber H or vessel A A', A' and I lead a tube K from the fluid chamber E
to the injector branch or nozzle F¹ so that the spray may be formed by the
issuing current of air from the delivery port or tube f leading from the cylinder
or vessel.
When providing for a door closing device upon my apparatus, I place a spring L

page_text: in combination with my cylinder piston or operating rod or lever which always-
tends to keep the door closed, or I place an ordinary spiral spring L¹ about
the axis of my lever pin M which by its torsional effect will serve the same
purpose.
To prevent the slamming of the door I may arrange that the air within my
compression chamber or within my cylinder shall act as a buffer or baffle stop;.
or I may provide a cataract arrangement of air escape within a separate portion.
of the cylinder or within a separate cylinder or chamber of my combination
apparatus.
may place my cylinder and injecting or spray producing apparatus upon the
door frame or upon the door itself allowing the operating rod B, piston rod B¹ cam
or lever to be placed either upon the door or upon the frame as may be desired for
any particular requirement.
I cover or enclose my perfume vessel or deodorizing vessel E' and the connecting
tube K within a casing or tube O as illustrated.
I sometimes surround my compression cylinder H with a chamber which I use.
as a spring box or which I may use as the fluid chamber when making a compact
apparatus.
I sometimes add inlet or non return valves to my cylinder or air vessel and
I may apply a valve or plate on the piston such as B2 permitting the air to pass from.
one side or end of the cylinder to the other.
I prefer to place rollers 61 upon my moving contact bars b so as to minimisė.
friction and to obviate noise.
I do not limit the application of my improved spray producing apparatus for
fitting to doors which require to have closing devices attached in combination but
I employ the improvements either with or without the door closing connections in
the manner hereinbefore described, and I sometimes provide disconnecting-
devices upon my apparatus such as outlet screws or caps N for allowing one to.
work without the other by causing the air to escape without producing a spray
when so desired.
I employ any suitable disinfectant or deodorizing agent or perfume in my
chamber or bottle E' from which the spray is produced.
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 ;-
1. Improvements in apparatus for attachment to doors or door frames having a
collapsible vessel plunger or piston for forcing air through an orifice and producing
a spray from liquid contained in a vessel attached or connected to the apparatus
substantially as hereinbefore described and as illustrated in the accompanying
drawings.
2. In spray producing apparatus described in the first claim the use of a nozzle
cap cover or valve for allowing the air to escape when it is desired to prevent the
spray from being forced into the room substantially as herein before described.
3. The combination of a spray producing apparatus with a door closing spring
or device substantially as hereinbefore described and as illustrated in the
accompanying drawings.
