PROVISIONAL SPECIFICATION.
Improvements relating to the Ventilation of Rooms.
JOHN LE MARCHANT BISHOP 100 Mosley Street, Manchester Insurance Agent
do hereby declare the nature of this invention to be as follows
An arrangement by means of which the air currents entering a room between
the door or window and its frame or jambs are conducted upwards and permitted to
escape into the room in an upward direction only, at a sufficient elevation to protect
the occupants of the room from the inconvenience and risk commonly incurred
through direct exposure thereto.
The space between each vertical edge of the door and its jamb, and between the
bottom edge and each lower vertical edge of the window and its frame, is covered
with an appliance of metal, leather, rubber, wood, or other suitable material, or
any combination of these, forming, when the door or window is closed, a channel
into which the air currents enter, and which, being closed at the bottom, and open
at the top, compels the currents to take an upward direction, as stated. The top
may, however, be closed whenever it is desired to prevent the currents from
entering the room by the ventilator.
If, and whenever so required, the appliance may be continued up to and along
the top edge of the door.
Dated 19th day of July 1890.

COMPLETE SPECIFICATION.
Improvements relating to the Ventilation of Rooms.
I JOHN LE MARCHANT BISHOP of 100 Mosley Street Manchester in the
County of Lancaster Agent 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 present invention relates to improvements applicable to the ventilation of
rooms and the objects of my improvements are to devise means whereby the lateral
air currents entering a room between the door and door jambs or frame or between
a window and its frame or casement are conducted vertically and subsequently
permitted to escape into the room in an upward direction and at a sufficient elevation
so as to protect any occupant of said room from the inconvenience and risk
commonly incurred by being exposed to any direct air currents as aforesaid and also
to utilize said air currents for ventilating the room.
In order to attain the said objects I employ a specially arranged appliance which
I illustrate in the accompanying sheet of drawings in which
Fig. 1 is an elevation of a door and door frame or jamb fitted with my improved
appliance.
Fig. 2 is a cross sectional plan taken on line a a of Fig. 1.
Fig. 3 is a front elevation of a door and door frame having a modified arrange-
ment of my improved appliance fitted thereto.
Fig. 4 is an enlarged cross sectional elevation taken on line b. b of Fig. 3 and
Fig. 5 is a plan of same.
ond
Fig. 6 is an enlarged cross sectional elevation taken on line c c of said Fig. 3.
Fig. 7 is an enlarged cross sectional elevation taken on line d d of Figs. 1 and 3

page_text: Fig. 8 is also a cross sectional elevation taken on line e e of said Figs. 1
and 3.
Fig. 9 is an elevation of a window sash and frame fitted with my improved
draught director and ventilating appliance.
Fig. 10 is an enlarged cross sectional plan taken on line f. f.
Fig. 104 is a like sectional plan illustrative of a modification of said appliance
and
Fig. 11 is a cross sectional elevation taken on line 9. g of Fig. 9.
Like letters of reference denote corresponding parts in each view.
Referring to Figs. 1, 2, 7 and 8 the space or crevice between each vertical edge
of the door H and the jamb J is covered with my improved appliance M which is
specially constructed of suitable thin steel or other metal made in the form of the
cross sections shown at Figs. 2, 7 and 8. Fig. 7 represents a section which covers
up the crevice at the opening edge of the door the said appliance M in this case
being made with two flanges m' and m². The flange m' is fastened to the door H
by means of screws or nails p and the flange m² receives a padding of rubber felt or
other pliable material m³ in order to form a draught-tight joint with the jamb J.
The appliance M which covers the crevice between the door H and jamb J on the
hinged edge thereof is arranged with flanges m' and m² which is hinged to the
remainder of said appliance M.
The appliance m² is nailed or otherwise secured to the jamb J and the flange m'
is nailed or otherwise secured to the door H.
The hinges m³ are well made so as to be of good fit in order to prevent any
unreasonable escape of the lateral draughts coming through the crevice. By means
of constructing the appliance M with the hinges m³ the door H can be freely
opened the middle portion of the appliance M is merely bent a little out of shape
in opening the door H wide but as the material of which the appliance M is
made is of a flexible nature it returns to its original form when the door H is
closed.
The lower end of the appliance M is closed as shown in dotted line Fig 1.
The lateral air currents entering through the crevices between the door H and
jambs J are conducted upwards by means of the appliance M and allowed to escape
into the room at m' thus preventing the usual draught and utilizing the same for
ventilating the room.
Referring to Figs. 3, 4, 5, 6, 7 and 81 arrange the door H and jamb J with two
vertical appliances and two horizontal appliances M the vertical appliance M at
opening edge of the door is made in cross section as shown at Fig. 7 and the
vertical appliance M on the hinged edge of door is made in form as shown at
Fig. 8. The horizontal appliance M which is secured to the top edge of door is
constructed in form shown in cross section Fig. 4 that is to say its flange m¹ is
secured to the door and its flange m² receives a piece of rubber or other padding m
so as to form a draught tight joint with the upper part of door jamb and this hori-
zontal appliance M is perforated with holes me as shown at Fig. 5. The lower
edge of door receives the horizontal appliance M which is constructed as shown in
cross section Fig. 6. The flange m¹ is secured to the door H and the flange m³ is
turned back and receives a piece of rubber or other like material m in order to
press down on the floor or door step so as to prevent any lateral draught. In this
arrangement the horizontal appliances at the upper and lower ends of door may be
hinged to or otherwise suitably connected with the vertical appliance at the hinged
edge of door H.
The lateral currents of air which would otherwise enter the room direct are
conducted by the appliances M upwards and are allowed to escape into the room
through the perforations m.
Referring to Figs. 9, 10, 10 and 11 the appliance M is secured to the vertical
side of the lower sash L and such appliance is made in form as shown at cross
section Fig. 10 that is to say the flange m' is secured to the window sash L and the
flange m² receives a piece of rubber or other like padding m³ which presses on the

page_text: window frame P in order to prevent the lateral air currents escaping direct into
the room.
Or the flange m³ may be fastened to the frame P and the flange m¹ receives
a strip of rubber or other padding m³ as shown at Fig. 104 in which case the
said appliance M may extend to any required height up the window frame or
casement P.
The lower part of the sash L may where preferred receive a horizontal
appliance M whose flange m¹ is fastened to the window sash L and the flange m².
receives a piece of padding of rubber or other like material m³ as shown and in this
arrangement the lateral air currents entering between the window sash L and
frame P are conducted and allowed to escape into the room in a vertical
direction at m².
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. The use of the specially formed channel section appliance M arranged to
intercept the air currents passing laterally between a door and door frame or jamb
and conducting the same in the manner and for the purpose specified.
2. The use of the specially formed channel section appliance M arranged to
intercept the air currents passing laterally between the window sash and frame or
casement and conducting the same in the manner and for the purpose specified.
