PROVISIONAL SPECIFICATION..
An Improved Apparatus for Purifying and Disinfecting Air.
We SAMUEL PHILLIPS, Tobacco. Merchant 39 Haymarket, London and
STEPHEN FARRINGTON SMART, Gentleman, 39 Haymarket London do hereby
declare the nature of this invention to be as follows :-
This device consists of a small drawer closely fitted to the inlet ventilating shaft
or tube. The bottom of the drawer is made of perforated metal, the holes punched
from the under side, thus raising the inner rims. The drawer is fitted with a layer
of sponge permitting the free ingress of air, but arresting smoke, fog, dust and
microbic germs. Resting on the drawer is a glass reservoir with outlets of small
capillary tubes for the equal distribution of a disinfecting and ozonizing liquid
which, at once destroys all germs arrested by the sponge, and, at the same time,
purifies and ozonizes the air before it passes into the room.

COMPLETE SPECIFICATION.
An Improved Apparatus for Purifying and Disinfecting Air.
SAMUEL PHILLIPS Tobacco Merchant 39 Haymarket London S.W. and
STEPHEN FARRINGTON SMART Gentleman 39 Haymarket London S.W. 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:-
This invention consists of an appliance to be inserted into intake air shafts for
the purpose of filtering the incoming air to enclosed spaces. The construction of
the apparatus is as follows-A frame is made to fit intake air shaft to which frame
is fitted a perforated metal inverted basin or wirework conc. Over the said basin
or cone is fitted sponge completely covering it, so that all air entering through the
intake air shaft must pass through this sponge. This sponge is about half an inch
or more in substance, and may be made of one or more pieces sewn together. It
is moistened with a disinfectant and kept moist by the following means. A bottle
of disinfectant is inverted & suspended from top of apparatus at about two feet
from sponge.
The neck of this bottle is plugged, a glass capillary tube passing
through centre of plug, inside capillary tube is a wick which can be adjusted by
its length to cause drops to flow from bottle at longer or shorter intervals. About
anidway between dropper and sponge is a stationary or revolving perforated disc
by means of which drops falling from dropper are broken up and scattered over
the sponge.
The entire apparatus can be put in and taken out of the intake air
shaft like a drawer, at pleasure, so that it can be cleaned and re-adjusted when
necessary.
The apparatus can also be hung in rooms, lavatories &c., and would then act as
an automatic diffuser of disinfectants.
The accompanying drawing shews the plan of my said invention, in vertical
elevation. A is the hollow cone-shaped sponge filter. B the frame. C the bottle
carriage. D the bottle for holding disinfectant. E the automatic dropper.
FF uprights to support bottle carriage. G the perforated wire disc, set at an
angle to receive & scatter drops from dropper.

page_text: Having now particularly described and ascertained the nature of our said inven.
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. Using sponge as an air filter in the manner above described.
2. The method of keeping sponge filter moist.
3. The perforated disc, as an automatic drop breaker & scatterer.
