Improvements in Spray Producing Apparatus for Disinfecting,
Deodorizing, and Purifying the Air in Apartments and the like.
I, JOHN WILSON BLACK, of 46 Academy Street, in the Town and County of
Inverness, North Britain, Bachelor of Medicine, 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 relatos to improvements in spray producing apparatus, and has for
its object the disinfecting, deodorizing, and purifying the air in apartments and
the liko.
The invention consists of an air pump of brass or other suitable material, which
is connected by means of a pipe or otherwise to the vessel containing the liquid.
The pump is so constructed that when a cord or chain or the like is pulled the
piston is drawn out and is thon forced back again by a spring arrangement fixed
inside. A current of air is thus forced from the pump through a tube which is
attached to the vessel containing the fluid intended to be used as a disinfectant,
deodorizer, or purifier. This vessel is inade of glass or other material, and has a
spray-tubo arrangement attached to it which causes it to discharge a quantity of
the fluid contained in the vessel in the form of spray.
In place of operating the pump by means of a cord or chain to force the current
of air into the vessel to cause the discharge of spray, this may be accomplished by
the opening of the door of the apartment.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings in the severnl
figures of which corresponding parts are marked with the samo lettors of reference.
Figure 1 is a perspective view showing parts of the apparatus in section.
A is the frame to which the apparatus is fixed, and B is the pump, of which C is
the barrel, and D the pistou. E is the spring for forcing back the piston after the
cord or chain I has been released, thus foroing a current of air from the pump B
through the tube F into the vessel G which contains the fluid to be used as a
disinfectant, deodorizer, or purifier. The pressure of the air on the fluid in the
vessel G forces a quantity of it up tho tube, and it is discharged in the form of
spray.
In Figures 2 and 3 I have shown my apparatus with the piston of the pump
operated by the opening of a door in place of a cord and chain as hereinbefore
described. In this case the pump B is attached to the door and wall of the
apartment by means of hinged or socket movable joints. When the door is opened
the piston D of the pump B is driven home as seen in dot and pick linos Figure 3,
and the current of air is forced from the pump B into the vessel G as herein before
described. The piston D of the pump B is thrown back by the spring E, and the
door of the apartment closed, or the spring may be dispensed with and the piston
thrown back by simply pulling the door shut.
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. The apparatus for producing a jet or jets of spray for disinfecting, deodorizing
and purifying the air in apartments and the like, substantially as described and
shown on the accompanying sheet of drawines.

shown on the accompanying sheet of drawings.
