Improvements in Means or Appliances for Ventilating and Regulating
the Temperature and Humidity of the Atmosphere in Spinning
and Weaving Factories and other Workrooms and Buildings.
We, BENJAMIN ORMEROD, Manager, of St. Thomas Terrace, JOHN FROST DAVIES,
Engineer, of Eden Street, and WILLIAM HAYTHORNTHWAITE, Manager, of Cherry
Tree, all Blackburu, in the County of Lancaster, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to improvements in means or appliances for ventilating and
regulating the temperature and humidity of the atmosphere in such places as spinning
and weaving factories but it is also applicable to other work rooms and buildings.
In spinning rooms and weaving sheds it is very desirable to maintain the
atmosphere at a constant uniform temperature with a suitable amount of humidity
and to effect this and also for ventilating purposes it is necessary to admit a constant
and regulated supply of fresh air in the desired condition.
In a simple arrangement according to our invention we employ a ventilating pipe
of suitable size (from which branches or other pipes may be supplied) open at one
end to the atmosphere or to any air supply and passing say from end to end or to
any part of the room. A supply of steam, air or water under pressure is introduced
through a small tube into the ventilating pipe preferably at the end outside the room
to be ventilated. The small tube can be placed either inside or outside the ventilating
pipe. This ventilating pipe and its branches have outlets at suitable places for the
discharge of air and moisture into the room means being provided for the escape of
water.
The amount of air and moisture carried into the room may be varied.
In place of using steam to induce the current of air water or air (hot or cold)
under pressure may be used.
When it is desired to admit more moisture the steam or other fluid employed to
induce the current of air forces the same through or between damped porous cloths
suspended tapes, threads, wick, or any suitable materials supplied with water by
capillary attraction or otherwise.
In place of using a ventilating pipe with one small steam supply pipe to induce
the air current and regulate the temperature the ventilating pipe could be enlarged
so as to admit of two or more steam water or air supply pipes or a combination of
steam water and air pipes could be used to induce a current of air to flow into the
ventilating pipe by which it would be distributed through the room to be ventilated.
We have described the use of steam water and air under pressure we may combine
these or any two of them for the purposes of our invention.
A propeller may be placed inside the ventilating pipe turned by steam air or
water impinging thereon.

Improvements in Means or Appliances for Ventilating and Regulating
the Temperature and Humidity of the Atmosphere in Spinning
and Weaving Factories and other Workrooms and Buildings.
We, BENJAMIN ORMEROD, Manager, of St. Thomas Terrace, JOHN FROST DAVIES,
Engineer, of Eden Street, and WILLIAM HAYTHORNTHWAITE, Manager, of Cherry
Tree, all Blackburn, in the County of Lancaster, 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 relates to improvements in means or appliances for ventilating and
regulating the temperature and humidity of the atmosphere in such places as
spinning and weaving factories; but it is also applicable to other workrooms and
buildings.
In spinning rooms and weaving sheds it is very desirable to maintain the
atmosphere at a constant uniform temperature with a suitable amount of humidity
and to effect this and also for ventilating purposes it is necessary to admit a constant
and regulated supply of fresh air in the desired condition.
In a simple arrangement according to our invention we employ a ventilating pipe
of suitable size (from which branches or other pipes may be supplied) open at one
end to the atmosphere or to any air supply and passing say from end to end or to
any part of the room. A supply of steam, air or water under pressure is introduced
through a small tube into the ventilating pipe preferably at the end outside the room
to be ventilated or it may be at each end. The small tube can be placed either inside
or outside the ventilating pipe in order to induce a current of air. This ventilating
pipe and its branches have outlets at suitable places for the discharge of air or air
and moisture into the room, means being provided for the escape of water.
The amount of air and moisture carried into the room inay be varied.
In place of using steam to induce the current of air water or air (hot or cold)
under pressure may be used.
And in order that our invention may be better understood and readily carried into
effect we will refer to the accompanying sheet of drawings.
In the said drawings Figure 1 represents part of the ventilating pipe a which is
furnished with any required or suitable number of perforations or openings al
preferably on each side. The pipe a is shown supported in this case in the wall b of
the building and its end is shown open to the outside atmosphere.
The small pipe c
is supplied preferably with steam to induce a current of air through the pipe, a
which may extend from end to end or through any part of the inside of the room,
the current of air and steam escaping into the room through the outlets a¹.
In place of using a ventilating pipe with one small steam supply pipe c to induce
the air current and regulate the temperature, two or more steam, water or air supply
pipes c or a combination of steam, water and air pipes c could be used to induce a
current of air to flow into the ventilating pipe a by which it would be distributed
through the room to be ventilated. An illustration of such an arrangement is shown
in Figure 2 where the use of three pipes c is indicated.
Figure 3 represents a main ventilating pipe a with two branches a¹¹. In this case
the air current may be induced by any suitable number of steam air or water pipes c
or a propeller d may be placed inside the ventilating pipe a as shown and be turned
by steam air or water impinging thereon and supplied through the pipe or pipes c.
The pipes a in each case preferably slope slightly towards one end, or any
equivalent means may be employed to provide for the escape of water. .
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The arrangement use and application of a ventilating pipe or pipes provided with

page_text: perforations or outlets through which air, or air and moisture is discharged, the
current of air or air and moisture being induced by a small pipe or pipes supplying
fluid under pressure substantially as and for the purposes herein described and as
illustrated by the drawings annexed.
