or Fresh Air to Rooms.
I, DAVID GILL, of Fairleigh, Weston-Super-Mare, in the County of Somerset,
Plumber, do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to isolate the air contained in rooms, from that
contained in the passages and staircases of dwelling houses, and to prevent the
entry of air into the rooms from such sources, and to provide for the entry of
warm or medicated air or air charged with disinfectants by means of improved
doors fitted to such rooms in suitable frames.
In carrying out my invention I fit the lintel and two door posts with rabbets,
and I form corresponding rabbets in the top and two sides or edges of the door.
I also form a hollow space in the lower part of the door, on the room side; and
in front of this space I fit a door or valve, with suitable means for opening and
closing the same. I connect this space with an under-groove, by making passages
or inlets thereto, in order to admit fresh or warmed air or medicated air, or air
charged with disinfectants or otherwise into the room, while the door is closed.
At the rear of this door or valve, I fit a grating, or a piece of perforated metal, or
some other suitable material, and in front of this I fix or suspend a flap or loose
piece of silk, or other suitable material.
I form grooves in the door and also in the door jambs and lintel (except in the
under part, which is otherwise fitted) with double rabbets or beads, in such a
manner as to fit against the door, when closed.
I provide a hollow space or opening in the lintel, similarly to that in the lower
part of the door, and fitted with proper means for opening and closing the same;
this space is connected with that in the upper part of the door, by means of the
grooves in the sides of the door above mentioned.
I provide and fix an oblong trough as an air passage, or as a receptacle for
disinfecting or other ingredients, formed of iron or other suitable material, in the
and
floor, immediately under the door, and extending the whole width of the door;

page_text: I fit thereto a self-closing valve or lid with pivots or hinges. When the door is
open this valve or lid closes by its own weight and leaves the floor quite flush.
A small crank and crank pin is fitted to the valve: when the door is closing it
touches this crank pin and thereby partially raises the valve: this movement
brings the lip of the valve in contact with the wall of the groove or rabbet of
the door, which places the valve in a vertical position, and forms a (practically)
air-tight joint.
I connect a metal pipe or pipes to the trough, and continue the same to any
suitable spot where fresh air can be best obtained, or to a chamber specially
constructed for such purpose or for providing warm air, or medicated or other
air for sanitary purposes or otherwise.
My invention admits of various obvious modifications.

I, DAVID GILL, of Fairleigh, Weston-super-Mare, in the County of Somerset,
Plumber, do hereby declare the nature of my said invention and' in what manner
the same is to be performed, to be particularly described and' ascertained in and by
the following statement :-
The object of my invention is to isolate the air contained in rooms, from that
contained in the passages and staircases of dwelling-houses, and to prevent the
entry of air into the rooms from such sources, by, means of improved doors fitted
to such rooms, in suitable frames.
In carrying out my invention I fit the lintel and two door posts with rabbets,
and I form corresponding rabbets in the top and two sides or edges of the door.
I also form a hollow space in the lower part of the door, on the room side, and
in front of this space I fit a door or valve, with suitable means for opening and
closing the same. I connect this space with an under-groove, by making passages
or inlets thereto, in order to admit fresh or warmed air to the room, while the door
is closed. At the rear of this door or valve, I fit a grating, or a piece of perforated
metal, or some other suitable material, and in front of this I fix or suspend a flap
or loose piece of silk, or other suitable material.
I form grooves in the door and also in the door jambs and lintel (except in the
under part, which is otherwise fitted) with double rabbets or beads, in such a
manner as to fit against the door, when closed.
I provide a hollow space or opening in the lintel; similarly to that in the lower
part of the door, and fitted with proper means for opening and closing the same;
this space is connected with that in the upper part of the door, by means of the
grooves in the sides of the door above mentioned.
I provide and fix an oblong trough as an air passage, formed of iron or other
suitable material, in the floor, immediately under the door, and extending the
whole width of the door; and I fit thereto a self-closing valve or lid with pivots
or hinges.
When the door is open this valve or lid closes by its own weight and leaves the
floor quite flush. A small crank and crank pin is fitted to the valve: when the
door is closing it touches this crank pin and thereby partially raises the valve:
this movement brings the lip of the valve in contact with the wall of the groove
or rabbet of the door, which places the valve in a vertical position, and forms a
(practically) air-tight joint.
I connect a metal pipe or pipes to the trough, and continue the same to any
suitable spot where fresh air can be best obtained, or to a chamber specially
constructed for such purpose or for providing warm air.

opened by a spring.
The channels m m are formed partly in the door frame and partly in the door,

completed excluded from the apartment.
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 :-
'
1. The arrangement of air channels formed in the door and frame substantially
as and for the purposes described and shewn on the drawings.
2. The general construction, combination and arrangement of the several and
respective parts, together forming my improvements in the construction of room
doors and door-ways for isolating the air in rooms from passages and stair cases,
and supplying warmed, medicated, disinfected, or fresh air to rooms, substantially
as herein before described and shewn on the drawings.
