PROVISIONAL SPECIFICATION.
An Improved Ventilator to be used for Ventilating or Removing Air
from Rooms, Railway Carriages, Drains, and the like.
We, Jonx WILLIAM MEADOWS PEYTON, of 28 Woodsley View, Leeds,
Yorkshire, Sanitary Engineer, and OSMOND YEADON RHODES, of 21 Leopold
Street, Leeds aforesaid, Electrician, do hereby declare the nature of this invention
to be as follows:-
Our invention consists in constructing a new form of device or apparatus
specially designed for ventilating or removing foul air from rooms, railway
carriages, drains, soil pipes and the like.
The form of apparatus we have adopted and employ for this purpose consists of
a vertical pipe or tube having around the periphery thereof a series of openings
carried up vertically in the form of small tubes and terminating within the central
tube some distance from the top thereof. These openings are larger at the inlet
than the outlet, so that as air enters the said openings and passes up through the
contracted parts or small tubes it will be compressed thereby, and thus acquire
velocity in ascending the several tubes, so that on the air entering the central tube
it will create an up draught therein, the suction of which draws the air upward
from the room or other place to which it is applied. In some cases it may be
advantageous to apply to the top of the ventilator a cap or cowl which will revolve
when acted upon by the wind. When this form of apparatus is applied to railway
carriages it may be necessary to cover the openings with wire gauze or other
suitable material in order to lessen the updraught which might be excessive in
consequence of the rapid motion of the train increasing the pressure of the air
upon it.

COMPLETE SPECIFICATION.
An Improved Ventilator to be used for Ventilating or Removing Air
from Rooms, Railway Carriages, Drains, and the like.
We, Jons WILLIAM MEADOWS PEYTON, of 28, Woodsley View, Leeds.
Yorkshire, Sanitary Engineer, and OSMOND YEADON RHODES, of 21, Leopold
Street, Leeds, aforesaid, Electrician 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:-
Our invention consists in constructing a new form of device or apparatus specially
designed for ventilating or removing foul air from rooms, railway carriages, drains,
soil pipes and the like.
Such being the nature and object of our invention we will now proceed to
describe the same more fully, and for that purpose make reference to the accom-
panying sheets of drawings illustrative thereof wherein Fig. 1 is an elevation of our
form of ventilator and Fig. 2 is a vertical section of same, which consists of a
central vertical pipe or tube A having around the periphery a series of bell-
mouthed openings B carried up vertically in the form of small conical tubes
terminating within the central tube at point C and some distance from the top of
the said central opening A. These openings B are of larger area at the inlet than
at the outlet, so that as air enters the said bell-mouthed openings and passes up

page_text: through the conical tubes, such air will be compressed thereby and acquire
increased velocity in ascending the several tubes, so that on the air entering the
central tube A the air ascending through the conical tubes will create an updraft,
the suction of which, draws the air upward from the room or other place to which
the ventilator is applied.
In Fig. 3 and 4 we have shewn the application to our ventilator of a stationary
cowl and marked D and E on the drawings, the latter of which may be used for
steam ships, whilst in Fig. 5 we have shewn the application to our ventilator of a
revolving cowl F.
When the ventilator is applied to railway carriages we cover the underside of
the central pipe A with wire gauze, network or other suitable material in order to
lessen the updraft which may be excessive in consequence of the rapid motion of
the train increasing the pressure of the updraft, but the said wire gauze or netting
may be placed within a pipe connected to the ventilator.
In Fig. 6 we have shewn the application of the ventilator to a greenhouse, in this
case we combine with the ventilator, a pipe G having a bell-mouthed orifice, such
pipe being extended downwards to reach near the bottom of the greenhouse so as
to draw away the foul and damp air emitted from the plants, which as is well known
is a heavy body and gravitates to the floor of the greenhouse.
In like manner the ventilator in combination with a pipe, may be connected to
drains, and soil pipes, as shewn in Fig. 7 and also to coal bunks, holds of vessels,
sleeping cabins, saloons, and other places and it will be found of great advantage in
ventilating the windows of shops where goods are exposed to the fumes of spent
gases, which goods frequently become deteriorated and damaged and their com-
mercial value reduced thereby.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
cinim is
Firstly. The construction of a ventilator, comprising a central vertical tube and
surrounded with conical tubes having trumpet shaped mouths as described, in
combination with a stationary or revolving cowl as shewn in Figs. 3, 4 and 5.
Secondly. The construction of a ventilator, comprising a central vertical tube
and surrounded with conical tubes, having trumpet shaped mouths as described and
shewn in the drawings, in combination with wire gauze or other form of network or
moveable grating for the purpose herein described.
Thirdly. The construction of a ventilator comprising a central vertical tube and
surrounded wit' conical tubes having trumpet shaped mouths as described and
shewn in the drawings, in combination with an extended vertical pipe as shewn in
Figs. 6 and 7.
