Improvements in Atomizers or syringes.
A communication by the BUTLER HARD RUBBER COMPANY, of 33 Mercer Street,
New York, in the County and State of New York, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil 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:
-
The invention relates to a device which may be used either as an atomizer or
a syringe, and is adapted to be instantly converted from one to the other, at will.
The invention is, moreover compactly arranged for carrying in the pocket, when
desired, and is especially adapted for that use.
Fig. 1 is a perspective view of a form of combined atomizer and syringe.
Fig. 2 is a central vertical section of the same.
Fig. 3 is a similar section of a modified form of atomizer.
Fig. 4 is a detail perspective view of the piston-chamber cap, and the piston rod
and handle.
Fig. 5 is a perspective view of the screw cap of the vial.
Fig. 6 is a cross section of the part 6, with attached parts in another position.
Fig. 7 is a detail view of the tip or part 6.
In the drawings, 1 represents a vial and 2 a pump chamber arranged side by
side, and preferably molded integrally. 3 represents an auxiliary chamber at one
end of the chamber 2, and separated therefrom by a diaphragm 4 5 is a cap enclos-
ing chamber 3.
The combined atomizer and syringe tip comprises an air tube 8, secured to
cap 5, and a liquid tube 7 leading from the bottom of vial 1 through an opening 9
into air-tube 8. 6 is a threaded tip of any approved exterior shape adapted to
screw on the end of air tube 8. The end of tube 7 projects beyond tube 8 and
when tip 6 is screwed up tightly (Fig. 2) so that tube 7 engages the aperture 6¹
the supply of air through tube 8 is cut off and only liquid through tube 7 will
he delivered. The device is then a syringe. But when the tip 6 is unscrewed
slightly so that tube 8 may deliver air also through the aperture 6¹, the liquid
delivered through tube 7 atomized; see Fig. 6.
When piston 12, by means of handle 13 and rod 14 is operated the air is driven
from the pump 2 through opening 10 (Fig. 2) into chamber 3, and thence into
vial 1 through opening 9, exerting a pressure upon the liquid which causes its
discharge through tube 7 as a syringe stream or as atomized, as heretofore
explained. In Fig. 3, which is purely an atomizer, the air is carried direct from
pump to the atomizer tip 16 by the tube 15, and a suction induced through the
tube 7 to atomize the liquid.
the

page_text: 11 is the cap for vial 1, and 21, the cap for pump 2. They open at opposite ends
of the device.
Cap 11 has a recess or recesses 25 cut in its threads longitudinally, so. that in
screwing on the cap any liquid which may be held in the threads of the vial or
cap will be forced out into the recess 25, and thence to the vial, instead of over-
flowing around the edges of the cap.
17 is a special cover adapted to cover both the vial cap and the atomizer or
syringe tip to protect the same, and also the clothing when carried in the pocket.
26 is a seat in top of cover 17 adapted to fit tightly upon the tip 6, and close same
when not in use.
20 are recesses in cap 21 adapted to receive projections 23 on rod 14, and hold the
rod against rotation while the handle 13 may be unscrewed from the position shown
in Figs. 3 and 4. In Figs. 1 and 2 the handle 13 is shown reversed, and its
thread 22 engages the thread on the outer end of cap 21, so as to close the vent
openings in the cap and prevent any leakage from soiling the clothing when not
in use.
18 is a screw nasal piece removably secured over atomizer 16 when desired,
and 19 is a screw cap for closing the mouth of the nasal piece 18, when not in
use. When in use cap 19 is removed from nasal piece 18 and screwed in to
handle 13.

The piston rod 14 is of molded plastic material, such as hard rubber, with a
metal core 27, which prevents any accidental breakage of the rod.
The tip 6 is so adjusted in its rotation that when the word " stream” is opposite
the representation of the arrow (Fig. 1) the device is a syringe and will deliver a
solid stream of fluid: and when either the words "oil" or water" are opposite
the arrow the device is an atomizer and will atomize oil or water respectively.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same is to be performed as communicated to
me.by my foreign correspondents, I declare that what I claim is :-
1. An atomizer comprising a plunger chamber and a vial located side by side
having a side wall common to both, an atomizer-tip and a cap for the vial at the
top and a plunger rod and a cap at the bottom of the atomizer, and a liquid tube
leading from the atomizer-tip through the common side wall to the bottom of the
vial
2. An atomizer comprising a plunger chamber and a vial located side by side
having a side wall common to both, an atomizer-tip and a cap for the vial at the
top and a plunger rod and a cap at the bottom of the atomizer, an auxiliary cham-
ber interposed between the atomizer-tip and plunger chamber, and a liquid tube
leading through the auxiliary chamber and common side wall to the bottom of
the vial.
3. An atomizer comprising a plunger chamber, a plunger rod, a detachable
handle for said rod, means for securing the handle to the rod; and means for
detaching the handle and securing it to the plunger chamber over the rod.
4. An atomizer comprising a plunger chamber, a plunger rod, means for lock-
ing the rod against rotation, a detachable handle for the rod, and means for secur-
ing the handle to the plunger chamber over the rod.
5. The combination of a plunger rod, a plunger chamber, means for positively
locking the rod against rotation and a threaded handle upon the plunger rod.
6. An atomizer comprising a plunger chamber, a plunger rod, a movable
handle upon the rod, interlocking means upon the chamber and the other end of
the rod for holding the rod against rotation while the handle is being removed or
replaced.
7. An atomizer comprising a vial and a plunger chamber located side by side
having a side wall common to both, a plunger having its handle extending out
through the bottom of the plunger chamber, an atomizer tip formed above the

page_text: upper
end of the plunger chamber, and the vial mouth formed at the upper end
of the atomizer at one side of the atomizer-tip.
8. In the combined atomizer and syringe, the combination with the reservoir,
of an air tube, a separate liquid tube having imperforate side walls, a longitu-
dinally movable tip surrounding the ends of both tubes, and adapted to be moved
against the liquid tube to cut off the air from the tip, and to be moved away from
the liquid tube to act as an atomizer, substantially as described.
9. In a pocket atomizer or syringe, the combination of a piston chamber and
a reservoir disposed side by side, the delivery tip and reservoir mouth being at
one end of the device, and a cover for both tip and reservoir mouth having a seat
adapted to close the opening in the tip, substantially as set forth.
10. In a pocket atomizer or syringe, the combination of a piston chamber and
reservoir side by side, the piston chamber being provided with a piston rod of
molded plastic material having a metallic core, substantially as set forth.
