ter and Builder. I, CHARLES CLAXTON, do hereby declare the nature of this inven-
tion to be as follows:-
-
Ventilator for large halls churches and factories. By means of a squar tube
to run outside of roof. 2 feet or more if required and to run through celling into
building this is to drain of hot atmosphere afixed to center tube, are four
siphons tubes same length as center tube made bell mouth top and bottom the
top bells have fans in to work on centers and are protected by wire netting, the
bottom bell has lids to stop ventilation if required worked by cords inside there
are tubes fixed to center tube to drain of heat out of roof. Between slates and
celling the the same will apply to a building without a celling.
Dated this 24th day of February 1898.

CHARLES CLAXTON, 11, Albion Terrace, New Fletton, Peterborough, Carpen-
ter and Builder, 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 is an invention designed to draw out hot air & gases from rooms schools,
chapels, churches, factories & similar large buildings, & to replace with fresh
air.
This is done by fixing a square shaft A about fifteen to thirty inches in diameter
from above roof, to the inside of room to be ventilated. The shaft to extend
about four feet above roof, & to be carried down to level of ceiling.
In the inside of bottom of shaft, the inlet will be reduced in size at about
two feet from the mouth, by the four sides being tapered from bottom upwards,
reducing the size of intake by about one quarter, N. The top will be covered
by a cone shaped cover, B designed to keep out rain, but to let out the hot air.
A shut-off door to be fixed inside shaft to close ventilation in cold weather,
to be worked with a cord, D.
The above shaft is solely for exhausting the hot air, & the size of same will
be governed by the building.
Between roof & ceiling, four to eight tubes E about six inches in diameter,
TD R71

page_text: are fixed in sides of shaft described above, at an angle of forty five degrees,
slanting upwards, to draw off hot air from inside of roof.
On the four sides of square shaft, are fixed four pipes F about six to nine
inches in diameter either square or round, the pipes to run through roof, & to
extend to within six inches of the top of exhaust shaft, and to about two feet
below mouth of same.
The top ends of pipes will be bent outwards with a right angle bend, The
mouths of pipes will be at least twice the diameter of the pipes themselves, &
will be bell or funnel shaped G.
The bottom end of pipes will be fitted with Ụ shaped bends, turning_outwards
& upwards to prevent sudden draughts, & will be bell shaped at ends H.
In the four inlets of tubes, which are outside the building, will be fixed or not,
according to circumstances, four fans to work automatically, J.
The end of tubes will be covered with gauze wire.
In the centre of each tube, situated between roof and ceiling will be fixed a
shut off valve K, for shutting off cold air, to work with cord L.
The above four tubes are to bring in cold air only.
On the outside of roof, the exhaust shaft and supply tubes will be cased in
with a cover M at top and sides as circumstances will permit.
Having now particularly described and ascertained the nature of my said
invention, & in what manner the same is to be performed I declare that what
I claim is
1. The construction of a ventilator with one square central outward flue, and
four inward flues arranged round it.
2. The inside of bottom of central outward flue reduced in size about two feet
from bottom.
3. The construction of an outward flue with several branch flue tubes be-
tween roof and ceiling as herein described.
4. The top end of inward flues of a ventilator to be bent outwards at right
angles and to be funnel shaped; and the bottom ends to be bent outwards and
upwards with a U bend, and to be funnel shaped.
Dated this 26th day of October 1898.
