Improvements in Appliances for Moistening, Heating, Cooling, and
Ventilating Factories, and other Buildings.
1, ROGER PYE of 69 Darwen Street. Blackburn in the County of Lancaster,
Mill Furnisher do hereby declare the nature of this invention to be as follows: —
The object of this invention is the moistening, heating, cooling, ventilating and
regulating of the temperature and humidity of weaving sheds, spinning mills, and
other buildings part of which invention is also applicable for other ventilating
purposes and the invention consists of improved appliances hereinafter described.
According to this my invention I employ a ventilating pipe of suitable and
requisite size open at its outer end to the atmosphere outside the building or factory
or the inlet end of the pipe may be made adjustable and the supply of air regulated
and guided by sliding or other door and the interior of the ventilating or air supply
pipe may have a steam coil pipe or pipes in it for the purpose of heating the air
passing through the said pipe. A supply of steam air or water under pressure or
a combination of two or more of these is injected into the supply pipe by means of
a valve constructed as follows:-
The valve is made somewhat similar to an injector the discharge end or ends
being preferably conical and one nozzle placed within another so that a supply of
water may be forced through one say the inner tapered or conical nozzle and a
supply of steam or compressed air may be directed through the outer nozzle which
is concentric to the inner nozzle and the water, and air or steam, meeting at the
point of discharge are together forced along the air supply pipe. The nozzles may
be so constructed that the inner one has not a direct supply of air or steam but
being perforated the air and water or steam are driven froin the outer nozzle through
the perforations and so along and out of the inner nozzle. Two or more concentric
nozzles may be employed in combination and also a solid plug or spindle in the
inner nozzle which serves to regulate the supply passing through the inner nozzle
its conical end by being moved nearer to or further from the discharge end of the
nozzle practically enlarges or lessens the size of same. The plug or spindle is
threaded and moved by hand wheel or other device and is provided with stuffing
box as ordinary. The inner concentric nozzles may also answer as a means of
adjustment for the outer one as by moving the inner nozzle in a similar manner to
the plug or spindle the supplys of air or Steam passing through the orifice of the
outer unzzle is regulated. The discharge end of the nozzles are directed into an
adjustable hollow truncated cone or funnel, and thereby a current of air from the
supply pipe is induced to pass through such cone or funnel, the discharge end of
which may be directed into a second adjustable hollow truncated cone or funnel
and others may also be added, in which case it may be advisable to add a second
air supply pipe with adjustable regulating door. The air water or steam after
passing through the last of the funnels or cones continues along the supply pipe
towards the room to be supplied, and passes through a tube composed of plain or
fluted porous tiles in the interior of the supply pipe. These porous pipes becoming
impregnated with moisture from the condensation of the steam or from the air and
water passing through them, serve to cool the air before passing into the branch
pipes which radiating from the main in various directions over the room or factory
carry the humid air to different and all parts of the factory and won required
deflecting plates are placed in various positions where necessary in the pipes to
direct the passage of the humid air. The branch pipes are provided with a
series of outlet holes or perforations for the distribution of the humid air in
the building. These outlet holes are provided with sliding doors whereby they may

page_text: be closed or partly so and the sliding door is carried on a wire or hinge fixed to the
outside of the pipe the slide passing through a slot to the interior of the said pipe and
over the outlet hole. By this arrangement the door or slide can be moved along
the slot and the wire or hinge thus opening or closing the outlet at will and the
door or slide being in the interior of the pipe no projection being below the outlet
hole no point or surface is presented for the collection of water of condensation and
thus objectionable dropping of water is obviated.
Preferably at or near the point where the steam and water or air enter the supply
pipe a draining pipe is applied for carrying away the water of condensation and
this is made the lowest point so that water will flow from all parts of the main
or branches.
By reversing the direction of the nozzle and cones or funnels the above described
appliances may be employed for removal of foul and vitiated air or air overcharged
with moisture from factories and buildings thus acting as an efficient exhaust
ventilator when from any cause this may become necessary.
In combination with the above described appliances may be employed appliances
for withdrawing the foul and heated air and gases from the shed factory or building
such appliances being constructed as follows:-
At or near the top of the room shed or building and above the branch pipes
for supplying the humid air I fix branch perforated pipes connected with a main
exhaust pipe preferably fixed in the centre of the shed and a current of air is
induced along the branch pipes and up the main exhaust or up the main and also
up larger concentric pipe or pipes placed round the main exhaust pipe by means
of the appliances hereinbefore described or by means of an exhaust fan placed at
the lower end of the main exhaust pipe such fan being preferably composed of and
constructed as follows:
A disc or flanged boss is keyed on the fan shaft this disc carries a number of lugs
which serve as receptacles for bolts or other attachments connected with one end
of each vane.
On the said shaft is a corresponding disc or flanged boss having similar lugs to
those on the first disc and which serve to carry the attachments connecting the
other edge of each vane so that it will be seen that as the discs are moved and set
more or less apart so will the angle of the several vanes be greater or less.
The vanes are preferably rectangular in form and in some cases I make each
vane in two parts divided down the centre but having an overlapping edge or
joint or curved part at the outer periphery the object of dividing the vanes is
that the separate parts may be set so as to act as independent vanes and the
curve serves mere thoroughly to collect and direct the air. When one disc is
drawn along the shaft that the vanes become parallel with the axis this will
adn:it of the vanes being folded or adjusted in a reverse position so that on rotation
being applied to the fan the direction of the current of air will be reversed and cool
air may be brought into the room or factory.
Branch exhaust pipes may be carried to all parts of the room or factory or
to the apex of weaving sheds and deflecting plates or mid feathers being placed
in the pipes serve to direct and guide the current of air.
In order to automatically close or open the outlet or inlet ways in the branch
pipes and thus regulate the temperature of the room or building the slides or doors
may be attached or connected to a rod or bar of copper brass or other metal which
is readily affected by variations in the temperature so that when the heat rises
above a given degree the ral expands sufficiently to open or close or partly
outlet or inlet according as mounted and desired.

Improvements in Appliances for Moistening, Heating, Cooling, and
Ventilating Factories, and other Buildings.
I. ROGER PYE, of 69 Darwin Street, Blackburn, in the County of Lancaster,
Mill Furnisher, 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 object of this invention is the moistening, heating, cooling, ventilating, and
regulating of the temperature and humidity of weaving sheds, spinning mills and
other buildings, part of which invention is also applicable for other ventilating
purposes and the invention consists of improved appliances hereafter described.
According to this my invention 1 employ a ventilating pipe of suitable and
requisite size open at its outer end to the atmosphere, outside the building or
factory or the inlet end of the pipe may be made adjustable and the supply of air
regulated and guided by sliding or other door and the interior of the ventilating or
air supply pipe may have a steam coil pipe or pipes in it for the purpose of heating
the air passing through the said pipe. A supply of steam, air, or water under
pressure or a combination of one or more of these is injected into the supply pipe
by means of a valve constructed as follows.
The valve is made somewhat similar to an injector, the discharge end or end
being preferably conical and one nozzle placed within another so that a supply of
water may be forced through one, say the inner tapered or conical nozzle, and a
supply of steam or compressed air may be directed through the outer nozzle which
is concentric to the inner nozzle and the water, and air, or steam meeting at the
point of discharge are together forced along the air supply pipe. The nozzles
may be so constructed that the inner one has not a direct supply of air or steam
but being perforated, the air, water, or steam is driven from the outer nozzle
through the perforations, and so along and out of the inner and outer nozzles.
Two or more concentric nozzles may be employed in combination and al-o n
solid plug or spindle in the inner nozzle which serves to regulate the supply
passing through the inner nozzle, its conical end by being moved nearer to, or
further from the discharge end of the nozzle practically enlarges or lessens the size
of the discharge orifice. The plug or spindle is threaded and moved by hand wheel
or other device and is provided with stuffing box as ordinary. The inner concentric
nozzles may also answer as a means of adjustment for the outer one, as by moving
the inner nozzle in a similar manner to the plug or spindle the supplies of air or
steam passing through the orifice of the outer nozzle is regulated. The discharge
end of the nozzle or nozzles are directed into an adjustable hollow truncated cone
or funnel and thereby a current of air from the supply pipe is induced to pass
through such cone or funnel the discharge end of which may be directed into
a second adjustable hollow truncated cone or funnel and others may also be
added, in which case it may be advisable to add a second air supply pipe
with adjustable regulating door. The air, water, or steam, or combination of
these, after passing through the last of the funnels or cones, continues along the
supply pipe towards the room to be supplied and may pass through a tube
composed of plain or fluted porous tiles in the interior of the supply pipe. These
porous pipes becoming impregnated with moisture from the condensation of the
steam or from the air and water passing through them. serve to cool the air
before passing into the branch pipes which radiating from the main in various
directions over the room or factory carries the humid air to different and all parts
of the room or factory, and when required deflecting plates are placed in variou-
positions where necessary in the pipes to direct the passage of the humid air. The
Branch pipes are provided with a series of outlet holes or perforation for the
distribution of the humid air in the building. These outlet holes are provided

page_text: with sliding doors whereby they may be closed or partly so, and the sliding door
is carried on a wire or hinge fixed to the outside of the pipe, the slide passing
through a slot to the interior of the said pipe and over the outlet hole. By this
arrangement the door or slide can be moved along the slot and the wire or hinge,
thus opening or closing the outlet at will and the door or slide being in the interior
of the pipe, no projection being below the outlet hole, no point or surface is
presented for the collection of water of condensation, and thus objectionable
dropping of water outside the pipe is obrinted.
Preferably at or near the point where the steam and water or air enter the
supply pipe, a draining pipe is applied for carrying away the water and water of
condensation and this is made the lowest point so that water will flow from all
parts of the main or branche-.
By reversing the direction of the nozzle and cones or funnels the above
described appliances may be employed for removal of foul and vitiated air, or air
overcharged with moisture from factories and buildings thus acting as an efficient
exhaust ventilator when from any cause this may become necessary.
In combination with the above described appliances may be employed appliances
for withdrawing the foul and heated air and gases from the shed, factory, or
building, such appliances being constructed as follows:-
At or near the top of the room, shed, or building, and above the branch pipes
for supplying the humid air, I fix branch perforated pipes connected with a main
exhaust pipe preferably fixed in the centre of the shed and a current of air is
induced along the branch pipes and up the main exhaust or up the main and also
up larger concentric pipe or pipes placed round the main exhaust pipe by means of
the appliances hereinbefore described or by means of an exhaust fan placed at
the lower end of the main exhaust pipe, such fan being preferably composed of
and constructed as follows.
A disc or flanged boss is keyed on the fan shaft, this disc carries a number
of lugs which serve as receptacles for bolts or other attachments connected
with one end of each vane.
On the said shaft is a corresponding disc or flange boss having similar lugs
to those on the first disc, and which serve to carry the attachments connecting
the other edge of each vane so that it will be seen that as the discs are moved
and set more or less apart so will the angle of the several vanes be greater or
less. The vanes are preferably rectangular in form, and in some cases I make
each vane in two parts divided down the centre but having an overlapping edge or
joint or curved part at their outer periphery, the object of dividing the vanes is
that the separate parts may be set so as to act as independent vanes and the
curve serving more thoroughly to collect and direct the air. When one disc is
drawn along the shaft that the vanes become parallel with the axis this will
admit of the vanes being folded or adjusted in a reverse position so that on
rotation being applied to the fan, the direction of the current of air will be reversed,
and cool or fresh air may be brought into the room or factory.
Branch exhaust pipes may be carried to all parts of the room or factory or to
the apex of weaving sheds and deflecting plates or mid feather being placed in the
pipes serve to direct and guide the current of air.
In order to close or open the outlet or inlet ways in the branch pipes and thus
regulate the temperature and humidity of the room or building the slides or doors
are attached or connected to a rod or bar of copper, brass, or other metal, which
has a rack formed on it and is operated by a small pur wheel on a shaft in or out-
side the main pipe, the shaft and wheels being turned by hand, all the outlet or
Sulet prforations can he opened or closed or partly so as required.
Such being the nature and object of my said invention, the following is a complete
de-cription of same reference being made to the accompanying drawings forming a

Fig. 13 is a detail of part of apparatus for operating the sliding doors.
According to this my said invention I employ a ventilating pipe 1 of suitable and
requisite size according to the room or building in which it is used, the pipe 1 is
open at its outer end 2 to the atmosphere outside the building, factory, or room,
and this inlet end may if desired, be made adjustable and the supply of atmospheric
air regulated and governed by sliding or other door or damper 2 and if it is
desired to supply warm or heated air to the room or building, 1 employ in the
interior of the ventilating or air supply pipe 1 (see Fig. 2) or in the tube of tile
pipes 17 (see Fig. 3) a steam coil pipe or pipes 3, the supply of steam or heated air to
such pipe or pipes 3 being regulated and controlled by the valve 5. The tube of
tile pipes 17 may be rendered inoperative so that hot air can be provided in winter
by lining same with a metal covering A (see Fig. 2A) such covering being inserted
through the door or doors 15. The pipe forming the coil 3 (see Fig. 3) may be
extended the whole length of the pipe i and provided with short branch pipes 1*
corresponding with the branch pipes 16 so that steam may be blown into all the
pipes to induce a current or to heat the pipes 16 and the room or building, the
excess of steam escaping by the pipe 3 communicating with the outside of
the building and provided with a damper 3. A supply of steam, air, or water
under pressure or a combination of two or more of these is injected into the supply
pipe and through the pipe 17 by means of a valve or injector 4 constructed as
follows and illustrated by Figs. 4, 5 and 6 of the annexed drawings.
The valve 4 is made somewhat similar to an injector, the discharge end or ends 6
being conical and one nozzle 6 placed within another 63 ¿e. concentric, so that a
supply of water may be forced through one, say the inner tapered or conical
nozzle 6 from the supply pipe 7 and a supply of steam or compressed air may be
directed through the outer nozzle 6' from the supply pipe 8 (see Fig. 5) the two
nozzles 6-6 being concentric so that the water and air or steam meet at the point
of discharge of the nozzles 6-6 and are together forced along the air supply, or
ventilating pipe 1. The nozzle 66' may be so constructed that the inner ore (i
has not a direct supply of air, steam, or water, but being perforated with holes as
at 10 (see Fig. 4) the air, or steam, or water are driven from the outer nozzle 6ª
Two or
through the perforations 10 and so along and out of the inner nozzle 6.
more concentric nozzles 6-6 may be employed in combination and also a solid
plug or spindle 9 (see Fig. 5) in the inner nozzle 6 (in lien of the hollow spindle 6

page_text: and perforations 10) which serves to regulate and govern the supply of air or steam
or water passing through the inner nozzle 6, the pointed or conical end of the
spindle 9 by being moved nearer to or further from the discharge end of the nozzle
practically lessens or enlarges the size of the discharge orifice.
If the inner cone
or nozzle 6 is employed for water it should be longer than the outer nozzle 6* so
that it projects beyond same or the pressure of steam if greater would be liable to
prevent water from passing through the nozzle. The plug or spindle 9 is threaded
as at 11 and turned and moved by hand wheel 12 or other device, and is provided
with a stuffing box 13 as ordinary. The inner concentric nozzle 6 also serves as a
means of adjustment for the outer nozzle 6" as by moving the inner nozzle 6 in n
similar manner to the plug or spindle 9, the supply of air, or steam, or water
passing through the orifice of the outer nozzle 6ª is regulated and controlled. The
supply of steam, or air, or water is carried to the valve or injector 4 by means of
the pipe or pipes 7-8 in which are valves such as at 12 for shutting off or con-
trolling the said supply to the pipes 7-8 being in communication with any
convenient source such as a steam boiler or cistern. By referring to Fig. 5 it will
be seen that the outer conical nozzle 6" can readily be removed from the injector 4
by simply unscrewing the same, and in Fig. + the injector is shewn with the
nozzle G (in Fig. 5) unscrewed and removed. At 13 is a chased or threaded
spindle for fixing the injector 4 in the required position. In Fig. 6 the spindle 9 is
shewn hollow and the water or steam supply pipe 9 passes through a stuffing box
in the centre of the hand wheel 12 so that the latter can be turned as ordinary
without steam or water escaping, thus the injector has two supply pipes 7-9*.
The discharge ends of the nozzles 6-6 of one or both injectors 4 when more than
one is employed (see Fig. 3) are directed into an adjustable hollow truncated cone
or funnel 14 and thereby a current of air from the supply pipe 1 is induced to pass
through such cone or funnel 14, the discharge end of which may be directed into a
second adjustable hollow truncated cone or fiumel 15, and others may also be added
if desired, two or three being found to give good practical results by more
thoroughly mixing the steam and air and inducing extra current, in which case it
may be advisable to add a second air supply pipe with adjustable regulating slide
door in addition to the inlet 2. The nozzle 6 in Fig. 5 can be screwed on the
injector shewn by Figs. 4 and 6.
The cones 14-15 are adjusted and set in the required position by the
brackets 14 access to same being had through a door or doors similar to 15
(see Fig. 3). The air or steam and water after passing through the last funnel 15
continues along the supply pipe 1, and through the tile pipes 17 towards the branch
pipes 16, and if it is desired to cool the air supply before passing to the room,
1 employ a tube 17 composed of plain or fluted porous tiles placed in the interior
of the supply pipe 1. This porous tube 17 becomes impregnated with moisture
from the condensation of the steam or from the air and water which passes through
(when the coil 3 is not supplied with steam or has cold water in it) and the rapid
evaporation caused thereby cools the air before reaching the branch pipes 16-16
which radiate from the main pipe 1 in various directions over the room, factory, or
building, and carry the humid and cool or warm air to different and all parts of the
factory, room, or building. To further cool the air supplied, cold water may be
passed through the coil of pipe 3 and thereby the tube 17 is cooled, whereas when
hot water or steam is passed through the coil 3 the tube 17 is heated and the heat
radiates therefrom and heat, the air.
When required or desired deflecting plates such as at 18-18 are placed in
various positions where necessary in the pipe 1 or pipes 1-16 to direct the passage
of the humid air. The branch radiating or distributing pipes 16-16 are provided
with a series of outlet holes or perforations 19-19 for the distribution of the
humid air in the building. These outlet holes or perforations 19 are provided
with sliding doors 20 (see Figs. 9. 10. 11) and whereby they may be closed or
partly so, and the sliding door 20 (see Fig. 9) is carried on a wire or hinge 21
fixed to the outside of the pipe 16, the slide 20 passing through a slot 23 to the

page_text: interior of the said pipe 16 and over the outlet hole 19.
By this arrangement
the door or slide 20 can be moved along the slot 23 and along the wire or hinge 21
ths opening or closing the outlet way 19 at will.
In Figs. 10-11 and 12 the sliding door 20 is shewn without the wire or hinge 21
and the lot 23 in the pipe 16, the lide 20 moving in slots or slide beds 24
formed in the interior of the pipes 16. The object and advantage gained by
placing the door or slide 20 in the interior of the pipe 16 is that there is no
projection or protruding point below the outlet hole 19 and thus no point or surface
is presented for the collection of water of condensation or other moisture and
thus objectionable dropping of water outside the pipe is obviated.
In order to open or close the outlet ways or perforations 19-19 in the branch
pipes 16 and thus regulate the supply of humid air, or air in the required state to
the room, building, or factory, the slides or doors 20-20 are attached or connected
by links or arms 25 to a rod or bar 26 of metal, and one of such rods or bars 26
extends the length of each of the branch pipes 16 either inside the same (see
Figs. 2, 11, and 13) or outside (see Figs. 3, 9, 10, and 12) and at one end of each
rod or bar 26 is formed a small rack 27. In or outside the main supply pipe I
is a rod or shaft of metal 30 on which are fixed a number of gear wheels 28-28
in gear with the racks 27, the racks on the rods in or outside the pipes 16 on
the right hand side of the supply pipe 1, being say on the top of the wheels 28
and the racks on the rods 26 in the pipes 16 on the left hand side of the main
supply pipe 1 being at the bottom of the wheels 28 (see Fig. 13), and the rod 30
is provided at its outer end outside the pipe 1 with a hand wheel 29 by which the
rod or shaft 30 and wheels 28 thereon can be rotated and the racks 27 on the
rods 26 caused to move laterally in opposite directions so that all the sliding
doors 20 can be operated at one and the same time and the perforations or
outlet holes 19-19 more or less opened or closed as required. It will be obvious
that the doors 20 can be opened independently by hand when the above described
apparatus is dispensed with.
When the rods 26-30 are outside the pipes small forks 25 are employed such
forks clipping the studs or pins 25 on the sliding doors 20.
Preferably at or near the point where the steam or air and water enter the
main supply pipe 1 a draining pipe 31 is fixed for carrying away water or water
of condensation and moisture, and this is made the lowest point or a "fall" in
this direction giver to the pipes so that water will flow from all parts of the
main or branches 16.
By reversing the direction of the injector 4 and cones or funnels 14, 15 so that
the jet of steam, or air and water is blown in a reverse direction, i.e. towards the
outer atmosphere the above described appliances may readily be employed for removal
of foul and vitiated air, or air overcharged with moisture from rooms, factories, and
other buildings, thus acting as an efficient exhaust ventilator when so desired.
In combination with the above described appliances, may be employed appliances
for withdrawing foul or vitiated air, or heated air and gases from the shed,
factory, or building, or such appliances may be used separately and are constructed
as follows :-
-
Preferably at or near the top of the room, shed, or building (see Fig. 1) and
above the main pipe 1 and branch pipes 16 for supplying the humit air as herein-
before described. I fix branch perforated pipes 33 connected with a main exhaust
pipe 34 preferably fixed in the centre of the shed or building, and a strong current
of air is induced along the branch pipes 33 and the main pipe 34, and up the
pipe 35 which extends to and communicates with the outer atmosphere by the
appliances hereinbefore described, or by means of an exhaust fan placed at
the lower end of the vertical exhaust pipe 35, such fan being preferably composed
of and constructed as follows:-
Two discs or flanged bosses 36-36 are keyed on the fan shuft 37 and these discs
or flanged bosses 36-36 serve as receptacle for the set screws or bolts 38-38
which fix the blocks 39-39 or other attachments connected with the vanes 40-40

page_text: which are fixed by screws 41-41 passing through slots to the arms or supports 42-42,
the ends 43 of which are rounded and screwed in corresponding holes in the
blocks 39-39 or other attachments. It will be seen that by this construction of
fan that if the dises 36-36 are moved and set, by set screws, inore or less apart, so
will the angle of the several vanes 40 be greater or less, and the current of air can
thereby be regulated and controlled.
The vanes 40-40 are preferably rectangular in form and slightly curved as
shewn, and towards their outer edges the curve serving more thoroughly to collect
and direct the air. The vanes 40 may be made in two parts as shown by Sheet 7,
also in detail one part overlapping the other and held together by screws passing
through slots so that the size of vane can be adjusted and regulated.
When one disc 36 is drawn along the shaft 37 until the vanes 40 become parallel
with the fan shaft 37 or axis, then the vanes 40 can be folded or adjusted in a
reverse position, so that on the fan being revolved, the direction of the current of
air is induced in a reverse direction, and cool or fresh air from the outer atmosphere
may be brought down the pipe 35 and forced along the main pipe 34 and branch
pipes 33 which may be carried to all parts of the room or factory, or to the apex
or highest points in weaving sheds (see Fig. 1) and deflecting plates such as 18
may be placed in the pipes, the fresh cool air is directed to all parts of the room,
or the foul and vitiated air drawn from all points thereof. The fan is driven by
pulley 45 and strap or rope from any convenient power and it will be obvious that
other and cheaper form of fan may be employed when it is not desired to reverse
the current of air.
The current of air induced by the fan (see Fig. 7) may be blown direct into the
vertical exhaust pipe 35 and thence into a hollow truncated cone or funnel 44 or a
series of such thereby to cause a more general current, the cones or funnels being
arranged as shewn by Fig. 2. The bottom of the cone 44 may be closed and
branch pipes radiating to different parts of the room, fixed therein.
The apparatus for withdrawing the air from a room or building, it will be
obvious, need not necessarily be placed at the top of the room or building, but
may be placed that the main and branch or radiating pipes are flush with the
floor or covered by gratings so that if the openings in the said pipes are placed
beneath any machine which causes a dust or obnoxious odour when in operation,
the air vitiated by the dust or odour is withdrawn before it ascends to the height
of the nostrils or mouth of the attendant on the machine.
Having now particularly described and ascertained the nature and object of my
said invention and in what manner the same is to be performed, I declare that
what I claim is :-
(1) The general construction, arrangement and combination of parts constituting
my improved appliances for moistening or henting, or cooling and ventilating, and
regulating the humidity and temperature of factories and other buildings operated
and operating in the manner described and substantially as illustrated by Figs. 2
and 3 of the annexed drawings.
(2) The main supply pipe 1, steam or air and water valve or injector 4, hollow
truncated cones or funnels 14-15, branch perforated pipes 16, and sliding doors 20,
all in combination as and for the purpose herein described and substantially as
illustrated by the accompanying drawings.
(3) The main supply pipe 1, steam or air and water valve or injector 4, branch
perforated pipe 16, sliding doors 20, all in combination either with or without the
