HERMANN SCHILDBERG, of Rodney Place, New, Kent Road, in the County of
Surrey, Merchant. "AN IMPROVED APPARATUS FOR SPRINKLING OR DISPERSING
IN SPRAY SCENTS, DISINFECTANTS, AND OTHER LIQUIDS."
The object of my present Invention is to improve the apparatus for which a
Patent was granted to me, No. 3957, dated October 26th, 1877, to disperse or
sprinkle in spray or sprays, scents, disinfectants, and other liquids, the scents
for perfuming rooms and other places, apparel, handkerchiefs, and the like, also
wherever and whenever desired, and the disinfectants for fumigating or purifying
rooms, carriages, apparel, bedding, water-closets, and other infected places and
things.
The said improvements are attained as follows:-
I take a convenient sized vessel or bottle, through the cork or other stopper of
which I pass and fit a short outer tube reaching a little below the said stopper,
through this tube I pass a smaller or inner tube reaching, with its addenda, nearly
to the bottom of such vessel. On the lower end of this inner tube I screw or other-
wise secure a cylindrical cap, the lower end of which cap is perforated with very
fine holes to prevent sediment or floating matter from passing up the tube with the
liquid. The said outer and inner tubes are so regulated and fixed as to leave
sufficient space between them for the passage of air when working the apparatus.
Around the upper end of the said outer tube I solder a shallow metal cylinder,
closed at the lower end, the upper part being closed by a disc fixed below the upper
edge of the said cylinder; in the centre of this upper disc a tube is fitted, pro-
jecting upwards some half inch (more or less), and having fitted under the bottom
of such tube, and to the underside of the said upper disc, a self-acting valve.
also provide a detached cylinder of such diameter as will enable it either to pass
inside or outside the previously-described cylinder; this cylinder is open at its
lower end, the upper end being covered with a disc or dome, in and through
which is inserted a tube, sufficiently small in diameter to work up and down in the
tube of the said upper disc. To each of these two cylinders I secure a short leather,
india-rubber, or other flexible or elastic tube or band, of a length suited to work
the said detached cylinder up and down without allowing their respective tubes to
leave each other, and thus forming a kind of bellows. A spiral spring is placed
I

in operating such bellows.
The side of the said bottom cylinder is perforated near its lower end, and in
this orifice I fit a conical or bell-mouthed short tube or nozzle; to the upper end
of the said inner tube, and at about right-angles thereto, and inside the said bottom
cylinder I solder a small tube, whose outer end is perforated with a fine hole, and
is placed within the said conical nozzle, both the outer ends of which being flush,
or thereabouts, with each other, and having an annular air space between them.
This arrangement is for producing a very fine or dust spray.
By placing the thumb or finger on the hole in the top of the upper cylinder and
somewhat quickly pressing down the same, then instantly releasing the thumb,
to allow the air to enter and the spring to lift up the said cylinder, and by con-
tinuing this operation successively, the air is forced into the said vessel, and being
condensed, forces the liquid in such vessel up through the said inner tube and out
at the upper small orifice thereof; at the same time and by the same pumping
operation, condensed air is forced out through the said annular space between the
conical nozzle and the said sinall tube, and mixing with the ejected liquid sends
forth a cloud of very fine or dust spray which quickly and freely mingles with the
atmosphere all around.
For producing a stronger jet of spray of the liquid from the vessel, I dispense
with the said conical nozzle and enlarge the orifice at the upper end of the said
inner tube according to the kind of jet desired. I also solder the upper or outlet
end of the said inner tube in the said orifice formed in the side of the cylinder and
thus close the air space around it. In this case the perforated cap on the lower
end of the inner tube may be dispensed with..
