Improvements in Atomizers and in Devices for Operating the same.
I, HERBERT JOHN ALLISON, of 52 Chancery Lane, London, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, which has
been communicated to me from abroad by Albert Leopold Cohn of the City and
State of New York, United States of America, Counsellor at Law, and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
My invention relates to improvements in atomizers and in devices for operating
the same, in which the disinfecting, deodorizing or perfuming is accomplished by
atomizing the disinfectant, deodorizer, antiseptic or perfume into the room or place to
be disinfected, deodorized or perfumed; and the objects of my improvements are
first to provide a means for atomizing the substance, powder or liquid into the place
and affording facilities for atomizing by the use of force or power originating at any
distance desirable from the place to be deodorized or perfumed; Second, to do both
these things in a cheaper, better or more lasting way than heretofore and by means
which will not easily get out of repair; Third, to keep the powder, substance or liquid
of a uniform strength.
I attain these objects by the mechanism illustrated in the accompanying drawing
in which,
Figure 1
a view of the entire apparatus showing the vessel containing liquid to
be atomized and its adjuncts partly in section and the cylinder of the air-forcing or
compressing device, the air-forcing or compressing device being attached to and
operated by a door.
Figure 2 is a perspective view of the disc and pipes of the atomizer.
Similar letters refer to similar parts throughout the several views.
In the place to be disinfected, deodorized or perfumed I place or attach the vessel a,
containing the liquid, disinfectant, or perfume to be atomized into the room; the
pipe b, of an atomizer has its one end immersed in the liquid and the other end in
close proximity to the end of the air pipe c, of the atomizer.
The pipe c, is by a pipe or tube (preferably a rubber tube) connected with an
air-forcing or compressing device attached to or connected with a door or other

page_text: S
movable object. In the drawing, the device for forcing air through the pipe or
tube C, is a cylinder A, which rests on two brackets o, o, attached to the casing of the
door, which brackets are provided with pivots p, p, on which the cylinder can turn;
piston, B is connected with the door itself by the bracket r, and moves on the pivot.
running through the piston near its end, and the pivot s, is held in place and moves
in the projections t, t, of the bracket r. The piston is also provided with the suction u
(see dotted lines Figure 1) which forces air out of the cylinder A, through the pipe v,
to which the air tube C, is attached.
When the piston is drawn out of the cylinder by the action of the door it sucks
air into the cylinder through the pipe c, C, v, and when the door is closed the piston
forces the air out through the same pipe v, C, c, and so atomizes the liquid in the
vessel a, into the circumambient air.
I also use the disc d, having a slot or cut e, which disc prevents evaporation, and
the slot together with the funnel f, allows the liquid which is drawn out and not
atomized to flow down into the vessel a, again. The disc performs the very important
office of keeping the liquid at a uniform strength by not allowing too much evaporation
to weaken it. This evaporation and consequent weakening has been a great defect
with other devices for disinfecting and perfuming where the whole surface of the
liquid has been exposed to the air.
The funnel f, has a flange m, and by means of the removable screw w, I screw the
flange of the funnel down on to the disc d, thus keeping the flange tightly in place
and also pressing the disc down closely to prevent evaporation from the vessel.
The disc rests on the narrow shoulder which runs around the bottom of the inside
of the neck g of the vessel. The screw works in the screw-thread in the neck g, of
the vessel a.
The screw is made short enough so that its upper end will be below the
opening n of the funnel. I prefer to use this screw instead of making the screw a
part of the funnel itself so that the hole n, is always on the side nearest the tube C,
which is more convenient, and which I could not depend upon if I were to screw
down the funnel tightly by a screw which were part of itself.
I prefer to solder the disc d, and the pipes cand b together. I put them in place by
taking hold of the funnel and the screw which rests on the flange of the funnel in
one hand and with the other hand I run the straight end of pipe e perpendicularly up
the funnel and when the end h, of the pipe c gets near the opening n, of the funnel,
I turn that pipe horizontally and run the end h through the opening. Then I immerse
the pipe 6 into the liquid while at the same time I place the funnel within the neck g,
of the vessel a and as the disc is soldered to the two pipes b, and c, the disc rests
in place by so immersing pipe b. Then I screw the funnel and disc both down tightly
by the screw w.
In the accompanying drawing I show only one way of accomplishing the objects
of my improvements but I also claim all substantially similar ways, which would be
necessitated by a different motive power than a near door. Different atomizers or
different air-forcing and compressing devices might be also used without departing
from my invention as the substance of my invention is having an air-forcing and
compressing device attached to some movable object and by means of a pipe or tube
connected with an atomizer operating on liquid to atomize it into any place to be
disinfected or perfumed, and even if the place into which the disinfectant, antiseptic,
deodorizer or perfume, is to be atomized is at a great distance from the movable object.
So that if in the house or neighborhood any door or other movable thing (whether
on the same floor or in a lower or higher floor) is especially adapted from its
frequent use to be connected with the atomizer, its motion can be utilized for my
improvement.
Prior to this invention, I was accustomed to operate perfuming and disinfecting
devices at a slight distance by the use of wires over pulleys, but these wires lose
some force over each pulley on which they are strung so that they cannot be made to
operate when stretched at some larger distance from the place to be operated upon as
they require so many pulleys that they are unreliable and in fact can only be used for
very short distances; besides the tension is likely to get them out of order; this is

page_text: not the case with my improvement as my improvement being pneumatic simply
employs air as the means to operate with.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is ;-
First. An air-forcing or compressing device operated automatically by a movable
object, and by means of a pipe or tube connected with an atomizer in a suitable
vessel containing liquid or powder to be atomized substantially as described.
Second. A vessel a, containing disinfectant perfume or the like to be atomized
having a slotted disc d and funnel f, substantially as and for the purpose specified.
