Improvements in the Heating and Ventilation of Work-shops of Dye-
ing Works, Cloth Finishing and Dressing Works, and all Work-
shops in which Large Quantities of Steam, Vapours, and Odours of
any kind are given off.
I, VICTOR HERCELLE-LERUSTE, Contractor for Plumbing and Zinc Work, of
Tourcoing (Nord), in the Republic of France, 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:-
The attempts hitherto made to get rid of the vapours arising during very cold
weather, and other times, in workshops where large quantities of vapour, steam
and odours are produced, have not been attended by satisfactory results, whatever
the system employed, hoods or steam chimnies, openings in the roof above the
dyeing vats, or other contrivance, the only result being the drawing up of the
heat from the dyeing vats and the work-rooms and not the vapours, which in
cooling, become condensed and descend to the ground and on to the goods and
the machinery.
The new combination forming the object of this application, consists, for dyeing
works, by way of example, of a building as shown in the accompanying drawings
in which Fig. 1 is a sectional elevation taken at A-B Fig. 3, Fig. 2 a similar
view taken at C-D Fig. 3, and Fig. 3 a sectional plan; or a construction of any
other form, whether vaulted, with ordinary flat ceiling, or having a dome, and
being either tiled or glazed, etc., in short, no matter what kind of construction,
with or without chimney and of any materials; -buildings in which the roof is
furnished with material for stopping up the chinks, so as to exclude external air,
this system being applied under the tiles, and effecting the joining of the glazed
portions. An inside ceiling of wood, felt or tarred paste-board, or a tarred or
enamelled ceiling or a ceiling of any other kind, capable of giving the same
results, forms, with that placed under the tiles, an isolated-air chamber, which
keeps the temperature inside the building at the same degree and prevents external
air from entering.
This heightened temperature in the interior of the building is produced by
means of heating pipes a of suitable shape and construction, placed opposite to
the suction openings b for the fresh air coming from outside, or from elsewhere.
This air, being heated upon entering the room keeps the temperature at the same
degree. The heat may be obtained by any other means according to the arrange-
ment existing in the works and factories; the air entering by the air openings.
is heated, or not, according to the temperature it is desired to obtain in the work-
shop.
A collection of ventilators and fans c carry off the air charged with moisture
and supplies fresh air in the work-shop, this moisture being no longer a vapour,
since, by the application of my system of stopping up the chinks and use of
materials which are non-conductors, etc., the condensing walls formed by the roof
are got rid of.
'

page_text: In the case of walls of but trifling thickness, also capable of acting as condensing
walls, in consequence of the porousness of the materials employed in their con-
struction, I apply my invention after the manner of tapestry, or I make use of a
partition formed of wood or other material and constituting an air-isolating
chamber, I thus obtain a result which is free of any large condensing surfaces
and obviates all vapours.
The system of heating and ventilation as described may also be employed for
maintaining a regular temperature.
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 combination of the system of stopping up the chinks and of the inner
ceiling in connection with the roofs and walls of work-shops, with the system of
heating and ventilation herein described, obviating at once vapours steam, odours,
and the like arising in the work-shops belonging to dyeing-works, cloth dressing
and finishing works, paper and other works."
2. The application of the system of heating and ventilation hereinbefore
described, comprising the stopping up of the chinks, and the arrangement of
heating pipes and ventilators to all kinds of rooms-likely to be affected by
vapours whether vaulted, above the ground floor, on the ground floor or otherwise.
