A New or Improved Ventilator or Device for Withdrawing Steam,
Vapour, and the like from Chambers:
I, WILLIAM TURNER CHARLTON of 40 Cambria Street, South Hylton,
Sunderland in the County of Durham, Contractor, do hereby declare the nature of
this invention to be as follows:-
This invention relates to an inproved ventilator or device for withdrawing steam,

vapour
To effect my purpose I use a telescopic or sliding tube arrangement the lower
end of the sliding portion being enlarged or cone shaped as required.
The fixed tube may lead to the atmosphere or through the roof of the chamber.
The sliding tube may be suspended or otherwise kept in position by means of
chains or cords passing over pulleys and balanced with weights connected to them.
The sliding tube, device working within the fixed tube can thus be lifted or
lowered by the weights and kept in any required position.
The device is specially applicable for the extraction of the steam arising from
the boilers of laundries, workmen's tea or breakfast rooms wash houses' and in
similar or equivalent. instances.

COMPLETE SPECIFICATION.
A New or Improved Ventilator or Device for Withdrawing Steam,
Vapour, and the like from Chambers.
1, WILLIAM TURNER CHARLTON of 40 Cambria Street, South Hylton,
Sunderland in the County of Durham, Contractor, 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 invention relates to an improved ventilator or device for withdrawing
steam, vapour and the like from chambers.
To effect my purpose I use a telescopic or sliding tube arrangement the lower
end of the sliding portion being enlarged or cone-shaped as required.
The fixed tube may lead to the atmosphere or through the roof of the chamber.
The sliding tube may be suspended or otherwise kept in position by means of
chains or cords passing over pulleys and balanced with weights connected to them.
The sliding tube device working within the fixed tube can thus be lifted or lowered
by the weights and kept in any required position.
The device is specially applicable for the extraction of the steam arising from
the boilers of laundries, workmen's tea or breakfast rooms, wash-houses and in
similar or equivalent instances.
In the accompanying drawings Figure 1 is a sectional elevational view and
Figure 2 an half sectional plan view on line ay in Figure 1.
These figures are illustrative of my invention and referring now to them a is a
fixed tube or chimney leading through roof R and a' is a sliding tube working
preferably within tube a.
The telescopic or sliding tube a¹ is hung or kept in position by any suitable
number of chains or cords c attached to the bell-mouthed base of the tube a', which

page_text: chains or cords pass thence over pulleys c¹ and thence downwards where they are
provided with counterbalancing weights W to balance the weight of the tube a¹ and
its bell-mouthed basal portion.
The apparatus will be found especially useful when fitted over boilers such as
are used in laundries and wash-houses and in similar situations, for the large bell-
mouthed base can be easily lowered over the steaming boiler and adjusted at any
required height when it will be found that not only is the vapour from the boiler
collected and ejected up the funnels a¹ and a but the room or chamber in the
vicinity of the apparatus will by the draught produced be to a great extent cleared
of vapour arising from the moisture on the materials taken from the boiler.
The apparatus may be constructed in sheet or cast metal and of any required
size or shape.
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 improved device for withdrawing steam or vapour from wash-houses and
similar or equivalent situations consisting in the combination with a fixed funnel a
of a telescopic or sliding funnel a' fitted with a bell-mouthed basal portion and
adapted to be raised or lowered and maintained at any required height by means of
weights hung on chains or cords passing over pullies and connected to the sliding
part a substantially as herein set forth.
