IMPROVEMENTS IN VENTILATION
Year: 1884

page_text: I, GEORGE WILLIAM WEBB of Reading in the County of Berkshire, Architect,
do hereby declare the nature of said invention for IMPROVEMENTS IN VENTILATION,
to be as follows:-
The
This invention has for its purpose the utilization of the heated gases from gas
during combustion, for carrying away the combusted products of the gas and
thoroughly ventilating Billiard and other rooms where much gas is used and to
this end the invention consists in using specially placed funnels-that is a funnel
placed above a shade for removing all vitiated air tobacco smoke &-connected to
iron pipes from 2 inches to 3 inches in diameter; the funnels which may be of metal
being placed about two feet above each gas shade. The tubes and funnels are to
be painted or enamelled inside to prevent the metal from corroding. Referring to
the accompanying drawing in which Fig. 1 is section of a Billiard room.
funnels B can either be permanently fixed, or, in the case of a low room be made
removable. The bottom edge of the funnel is turned up all round to form a gutter
to catch any condensation that may arise in the pipes. The pipes C or some of
them are made to enclose the gas pipe, leaving a cavity all round for the foul air to
pass up. The heat from the gas warms the funnels and causes them to suck the
foul air towards them, when it goes up with a rush. A foul air chamber D is
formed above into which the tubes are conducted and the vitiated air received; it
is then drawn off by means of an exhaust ventilator A on the top-the continuous
current of air up the pipes drawing the vitiated air after it causes perfect
ventilation. When used over a billiard table the funnels being placed say 2 feet
above the shades renders it unnecessary to remove them in the day time as no
shadows are thrown on the table-if they were placed lower down a shadow would
be cast on the table. In combination with the above improvements the invention
comprises the modes of admission of fresh air supplied by means of funnel air inlets
in the floor under the billiard table K. The air to be regulated by means of a
slide on the top. These inlets may be of any shape or form desired so that they
are funnel shaped to allow the air to spread and may or may not be covered with
perforated zinc or other metal.

page_text: I, GEORGE WILLIAM WEBB, Associate of the Royal Institute of British
Architects, of Reading in the County of Berkshire, Architect, do hereby declare
the nature of my invention for IMPROVEMENTS IN VENTILATION, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
This invention has for its purpose the utilization of the heated gases from gas
during combustion, for carrying away the combusted products of the gas and
thoroughly ventilating Billiard and other rooms where inuch gas is used and to
this end the invention consists in using specially placed funnels-that is a funnel
placed above a shade for removing all vitiated air tobacco smoke &c. connected to
iron pipes from 2 inches to 3 inches in diameter, the funnels being circular, square,
octagonal or any other desired shape ornamental or otherwise and may be of metal
or other material being placed about two feet above each gas shade. The tubes
and funnels are to be painted with red lead or enamelled inside to prevent the
metal from corroding. Referring to the accompanying drawing. The funnels B
can either be permanently fixed, or, in the case of a low room be made removable.
The bottom edge of the funnel is turned up all round to form a gutter to catch any
condensation that may arise in the pipes. The pipes C or some of them are made
to enclose the gas pipe F, leaving a cavity all round for the foul air to pass up.
The heat from the gas warms the funnels and causes them to suck the foul air
towards them, and conducts it into the hollow bosses or collectors E from there it
goes up with a rush. A foul air chamber D is formed above into which the tubes
are conducted and the vitiated air received; it is then drawn off by means of an
exlinust ventilator A on the top-the continuous current.of air up the pipes
drawing the vitiated air after it causes perfect ventilation. When used over a
billiard table the funnels being placed say 2 feet above the shades renders it
unnecessary to remove them in the day time as no shadows are thrown on the
table if they were placed lower down a shadow would be cast on the table and
the uptake shafts overheated. They also cause all tobacco smoke to be taken far
above the players head leaving the table perfectly clear which would not be the
case if they were brought down to the gas shades as the smoke would then be
collected under the shades and be a very serious objection, being below the level of
the players heads and highly injurious. In combination with the above improve-
ments the invention comprises the modes of admission of fresh air supplied by
ineans of funnel air inlets in the floor. The air to be regulated by means of a slide
on the top. These inlets may be of any shape or formn desired so that they are
funnel shaped to allow the air to spread and may or may not be covered with
perforated zinc or other metal.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I would state that I
do not confine myself to the precise details herein described or delineated as the
same may be varied without altering the characteristic nature of my invention but
what I claim is :-
The ventilating or carrying off the products of combustion of gas lights by means

page_text: of one or more uptake shafts painted or enamelled inside and combined with one
or more funnel receivers over such gas lights but disconnected therefrom all in the
manner substantially as described and as illustrated.
