Improvements in Disinfecting or Perfuming the Air of Water Closets
and the like.
_ I, JAMES AUGUSTUS LIPPINCOTT, of 6, Price Street, Liverpool, in the County of
Lancaster, Commission Agent, do hereby declare the nature of this invention to be
as follows:-
This invention has for its object an arrangement for disinfecting or perfuming
the air of water closets and the like every time the door is opened or closed.
al
In carrying my invention into effect, I mount the cylinder of an air pump to
the doorway framing by means of a trunnion so as to oscillate with the opening or
closing of the door. This cylinder is fitted with a piston rod or plunger, one end
of which has a piston working in the cylinder, and the other pivoted to a pin or
pivot which is fastened to the door in such a way that the opening and closing
of the door shall work the piston in the cylinder. In a suitable position, a bottle
or container of liquid disinfectant or perfume is provided having an atomiser for
injecting the liquid in the bottle into the room in the form of spray. This atomiser
on the bottle is connected with the pump on the door by a flexible tube so that by
one movement of the door, either closing or opening, air shall be drawn in the
bottle, and by the other movement of the door, either opening or closing, as the
case may be, this air shall be passed through the atomiser and thus spray a quantity
of the disinfectant or perfume into the air of the room. In order to assist in this
work and to enable the door to close rapidly and thus spray forcibly, I may place
spring and (or) air buffer on the door, or this spring may be combined with the
air pump. Where however one movement of the door simply draws air in, and the other
movement ejects disinfectant in the form of spray through the nozzle, the use of this
spring is not as a rule necessary. The air pump I prefer to employ is a simple cylinder.
A pneumatic ball however could be used instead. It is obvious that instead of
the atomiser described, it may consist of a tube with a nozzle at one end from
which the atomising blast is ejected by the air pump. A blast of air ejected
through this nozzle will, in such case, be presented at right angles across an open-
ing in the end of another tube, which communicates with the supply of liquid
disinfectant in the bottle. The atomising blast is thus ejected by the opening
for closing of the door, the blast crossing the orifice of the tube leading from the
bottle of liquid disinfectant whose contents are thereby raised, ejected at. the
nozzle and reduced into fine spray.

I, JAMES AUGUSTUS LIPPINCOTT, of 6, Price Street, Liverpool, in the County of
Lancaster, Commission Agent, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
.......
This invention has for its object an arrangement for disinfecting or perfuming
water closets and the like every time the door is opened and closed. It will be
understood from the following description, reference being had to the accompany-
ing drawing, in which:-
Figure 1 is a front elevation with door closed,
Figure 2 a plan of the invention with door partly open, and
Figure 3 a detail view on an enlarged scale of the atomizer.

In these, A is the door, B the cylinder of an air pump fitted to the doorway
framing, by means of a trunnion C so as to oscillate with the opening and closing
of the door, D a piston rod or plunger, one end of which has a piston working in
the cylinder, and the other pivotted to the pin E which is fastened to the door in
such a way that the opening and closing of the door shall work the piston in the
cylinder B, F a bottle or container, of liquid disinfectant or perfume-having an
atomizer or sprayer G for injecting the liquid in the bottle into the room in the
form of spray. This atomiser is made with a spray tube g which dips down into
the liquid in the bottle, and is connected with the air pump on the door by the
flexible tube 'H, g' is an extension tube which enables the device to be fitted to
bottles of various depths. By one movement of the door, say the opening, air, is
by suction drawn through the liquid in the bottle from the immersed tubes g.and gl
into the upper part of the bottle, from whence it is conveyed to the cylinder. B
by the tube H, then by the reverse movement of the door this air in the cylinder
is forced back along the tube H, compressed in the bottle above the liquid, the
action of which is to force out through the tube of the atomizer an equivalent
quantity of the liquid disinfectant, thereby discharging through the nozzle a
spray of disinfectant into the air of the room. The action of the atomizer there-
fore depends upon the compression of the air above the liquid in the bottle, in
which liquid the atomizer tube is immersed.
.
In order to assist in this work and to enable the door to close rapidly and thus
spray forcibly, I may place a spring or air buffer on the door, or this spring may
be combined with the air pump. Where, however, one movement of the
door simply draws air in, and the other movement ejects the disinfectant
in the form of spray through the nozzle, the use of this spring is not as
a rule necessary. The air pump I prefer to employ is a simple cylinder. " A
pneumatic ball could, however, be used instead.
?
It is obvious that instead of the atomizer described, it may consist of a tube
with a nozzle at one end from which the atomizing blast is ejected by the air
pump.. A blast of air ejected through this nozzle will, in such case, be presented
at right angles across an opening in the end of another tube, which communicates
with the supply of liquid disinfectant in the bottle. The atomizing blast is. thus
ejected by the opening or closing of the door, the blast crossing the orifice, of the
tube leading from the bottle of liquid disinfectant whose contents are thereby
raised, ejected at the nozzle, and reduced into fine spray.

page_text: 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. A disinfecting apparatus for water closets, consisting of a bottle or con-
tainer for holding the disinfectant liquid, an atomizer fitted to the bottle for
spraying the disinfectant into the room, in combination with an air pump worked
by the door and connected with the atomizer on the bottle, in such a manner that
by one movement, say the opening, air shall be drawn through the liquid in the
bottle into the cylinder of the air pump and by the reverse movement this air
shall be forced back and compressed above the liquid in the bottle, forcing out an
equivalent quantity of liquid through the atomizer in the form of spray into the
apartment, substantially as described.
2. The general combined arrangement and construction of parts substantially
as set forth.
