PROVISIONAL SPECIFICATION.
An Improved Method of Isolating Rooms in Private Houses and.
other Buildings.
I, DAVID GILL of High Street in the Town of Weston super Mare, in the
County of Somerset Sanitary Plumber, &c., do hereby declare the nature of this.
invention to be as follows:-
My invention consists in isolating rooms by means of an intercepting chamber
into which fresh air is introduced at the door entrance to the room or apartment.
This chamber is formed by means of an air tight screen, forming a recess on one
side, and having on the other side an additional door to the entrance door, so that
before the inner door can be opened, the outer door must be closed, and when the
outer door is closed, a person entering the room from the chamber can open the.
inner one and vice versa, thus cutting off all connection between the air of the room.
and that of the house or building. In this manner perfect isolation is established
continually. This chamber is covered in at the top and can be kept filled with
disinfecting fumes or medicated vapour suitable to the case.
In private houses this chamber can be temporarily constructed on an emergency
so that an infectious case can be safely treated in the patient's home without risk to.
other occupants of the house, or danger in conveying the patient to a statutory
hospital.
Dated this 29th day of December 1892.

COMPLETE SPECIFICATION.
An Improved Method of Isolating Rooms in Private Houses and
other Buildings.
I DAVID GILL of High Street in the Town of Weston super Mare, in the
County of Somerset, Sanitary Plumber, 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 :-
My invention consists in isolating rooms by means of an intercepting chamber
into which fresh air is introduced at the door entrance of the room or apartment.
This chamber is formed by means of an air-tight screen or recess having a door on.
the inner side of the room in addition to the outer entrance door in such manner
that before the inner door can be opened the outer door must be closed, and when
the outer door is closed a person entering the room from the chamber can then open
the inner door to the room and vice versa, thus cutting off all connection between the
air in the room and that of the house or building. In this manner perfect isolation
is established. This chamber is covered in at the top and can be kept charged with
disinfecting fumes or medicated vapours suitable to particular cases, and can be
constructed for temporary use on an emergency, and thus an infectious case may be
treated in the patient's home or dwelling without risk to other occupants of the house.
Fig. 1. is a vertical section of the chamber. A is the inner door with spring or
other appliance to keep it closed. B is the outer door with similar appliance.
C is the screen framing. D is a box with lids (closing with their own weight) for
putting in medicines or food to the nurse, when not necessary to open the door on
the inner side. E. is an exit ventilating pipe to the chamber from which a pipe is.
carried to the flue or by other means to the open air. The air inlet would be by
another pipe from the open air passing under the flooring of the chamber or by any
other ineans most convenient.

page_text: Fig. 2. is a plan of the chamber. A. is the inner door (as aforesaid). B. the
outer door. C. the screen-framing. D the box for putting in medicines or food.
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 :-
An improved method of isolating rooms for infectious cases by means of an
intercepting chamber having fresh air introduced therein, with disinfecting vapours
if required, and two doors to the chamber constructed in such a manner that one of
the two doors must be closed before the other is opened for either egress or ingress
to the patient's room, all substantially as described.
