WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN ATOMIZERS OR APPARATUS
FOR DIFFUSING LIQUID PERFUMES." A communication from abroad by Thomas
Jefferson Holmes, of Boston, Massachusetts, United States of America.
This Invention relates to certain improvements in atomizers, and consists,―
First. In the arrangement of the air valve on the opposite side of the central
portion to that in which the discharge orifice is located, whereby the necessity of
providing the air bulb with a valve and the objections incident thereto are avoided.
The said Invention also consists in providing an atomizer with an adjustable
nozzle, whereby the quantity of liquid ejected may be varied, the nozzle being also
made removable in order that access may be afforded to any obstruction at the dis-
charge orifice or "atomizing point," thus facilitating its removal.
The said Invention also consists in the combination with an atomizer of a hollow
screw shank passing through the stopper, by which construction the stopper is
securely held in place, and when worn out can be readily removed from the screw
shank and replaced by a new one.
The said Invention also consists in casting in a single piece the hollow screw
shank to which the stopper is secured, the bub support, and the portion between
them in which the air valve is located, whereby the construction is simplified and
the cost reduced.
The said Invention also consists in providing the central portion with a screw
thread for the reception of the upper end of the liquid tube in combination with the

page_text: Figure 1 is an elevation of an atomizer constructed in accordance with my
Invention Figure 2 is a vertical section through the centre of the same.
A represents a bottle, in the mouth of which is fitted the stopper a provided with
a central hole extending vertically through it for the passage of a screw shank b,
projecting down from the under side of a metallic cap c formed at the base of a
central portion d, at the top of which is formed the cup-shaped support c, to which
the air bulb B is secured by means of a hollow rerewf, which communicates with a
vertical passage / leading into the horizontal air passage i, at one end of which is
located the atomizing point k, and at the other end the valve l, through which the
air for supplying the bulb B is admitted. C is a nozzle, a portion of the interior
of which is provided with a screw thread which fits over a corresponding screw
thread on the part g of the central portion d, by which construction the nozzle may
be turned so as to change the relative distance of its aperture or discharge orifico 8
from the end of the part g, and thereby increase or diminish the quantity of spray
which escapes from the discharge orifice 8, the nozzle being readily taken off to
obtain access thereto for the purpose of removing any obstruction which may lodge
at or near this point.
By locating the bulb B in or nearly in lino with the liquid tube and above the
bottle A, the atomizer may be readily grasped and operated by one hand only.
The bottom of the central portion is provided with a screw thread, into which
is screwed the upper end of the tube it, through which the liquid in the bottle A is
forced into a horizontal passage n, and thence through a channel 9 formed in the
under side of the part g to the atomizing point, where it is dissipated into spray
by the current of air passing through the passage i, which creates a vacuum at this
point, and thus causes the liquid to be forced up the tubo m to the atomizing point,
the air being admitted into the bottle to create the desired pressure upon the
surface of the liquid therein through a veut 10, which communicates with the
space 12 between the liquid tube m and the interior of the screw shauk b.
By the application of a screw shank b to an atomizer as above described, the
stopper a is kept in place thereon, and all danger of its being accidentally separated
therefrom is avoided, the stopper when unfit for use being readily unscrewed and
a new one substituted therefor.
The hollow screw shank b, bulb support e, and central portion d between them
are cast in a single piece, whereby the construction is simplified, the cost reduced,
and the liability to get out of order diminished.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
First. The arrangement of the air valve on the opposite side of the central
portion & to that in which the discharge orifice is located, as above set forth and for
the purpose specified.
Second. An atomizer provided with an adjustable and removablo nozzle C at the
point where the liquid is discharged, as above set forth and for the purpose
specified.
Third. The hollow screw shank 6 passing through the stopper a in combination
with an atomizer, as above set forth and for the purpose specified.
Fourth. The hollow screw shank b, the central portion d, and bulb support e, all
combined and cast in the same piece, as above set forth and for the purpose
specified.
Fifth. The central portion d provided with a screw thread for the reception of

page_text: the upper end of the liquid tube m, in combination with the hollow screw shank b,
as above set forth and for the purpose specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fifth day of May, in the year of our Lord One thousand
eight hundred and seventy-six.
