ADOLPHE EMILE HUBERT and WILLIAM EDWARDS Engineers trading as
Banner Sanitation Co., 24, Craven Street, Charing Cross, London, W.C. do
hereby declare the nature of this invention to be as follows:-
A jet or nozzle emitting steam, compressed air or gas, either in the form of a
solid jet or through an anular orifice or orifices, the opening or openings of which
are regulated by the action of a plug, handle, key or spindle, so constructed as to
cause a radial & axial motion to the plug in such a manner by the action of a cog
wheel or ratchet, or that of two bevelled cog wheels, or screw or worm, as to operate
at the same time in such a manner as to open or close the orifice or orifice's for
emitting steam compressed air or gas & at the same time acting upon a dial or
indicator so graduated at the opposite end, or at right angles, to, the jet, as to
clearly show to what extent the orifice or openings are open or closed, & like-
wise upon a dial fitted at the side, either under or around the handle thus affording
one or two distinct points at which the condition of the openings can be radily
seen, calculated or set.

Improvements in Steam or Compressed Air Nozzles, more especially
applicable in connection with Ventilation or Forced Draught for
Boilers and Furnaces.
We ADOLPHE EMILE HUBERT and WILLIAM EDWARDS trading as Banner
Sanitation Company of 24 Craven Street Charing Cross London 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 nozzles for the emission of steam or compressed air or
other gas to induce or produce currents of air and the object thereof is so to
construct and fit the same and to provide therein and therewith such appliances and
devices that the annular orifices thereof can easily and quickly be regulated or that
is to say the areas of such orifices can be altered and adjusted being made larger or
smaller at pleasure and that the exact conditions from time to time and at all times
of these annular orifices or that is to say the extent to which they are opened or
closed can readily and plainly be observed and noted. These our nozzles will be
suitable for use everywhere and for all purposes but they are perhaps more
especially applicable for and in connection with ventilation and forced draught for
boilers and furnaces and when they are to be used with steam or hot gases or in
hot places the handles by which the same are actuated can be kept quite cool
which obviously is a very great advantage and excellence.
In order the more clearly to explain this our invention and in what manner the
same is to be performed we refer to the accompanying drawing wherein
Figure 1 is a longitudinal section of a most convenient form and style of

page_text: construction of our nozzle as arranged to deliver one annular jet of steam or
compressed air or gas and Figure 2 is an elevation of the rear end of the same.
A cylindrical or other casing A is made of any suitable metal or material and of
the desired size and proportions the one end A¹ of which casing A is open while
the other end is made in the shape of a truncated cone B and the steam or air or
gas is admitted into the casing A through an aperture C provided with a collar
situated near to the conical end B of such casing A. A spindle D passes
longitudinally and centrally along and through the casing A on the one end of
which spindle D outside the casing A is secured by its apex a conical valve E
which can close the mouth of the truncated cone B this mouth forming a seat
therefor and the valve E can most conveniently be made in the shape of a double
cone the bases of which cones are in conjunction. The spindle D is supported and held
in position through and by means of a diaphragm F made with or attached to the
casing A to which diaphragm F is connected or wherewith is made an elongated
bearing H extending towards the valve E and surrounding the spindle D and in this
bearing H is a female screw thread wherein a complementary male screw thread on
the spindle D engages and therefore when this spindle D is rotated on its axis the
valve E is raised off or drawn down on its seat at the mouth of the truncated
cone B the spindle D obviously having both rotary and longitudinal movements and
these screw threads are preferably so constructed and arranged with such a coarse
pitch that one complete rotation on its axis of the spindle D will raise the valve E
off its seat so far as is to be permitted and therefore will open the annular orifice
therearound to its largest extent and any suitable stop or similar appliance may be
fitted or arranged to and with or on any convenient part of this apparatus to
prevent any further raising of the valve E. The other end of the spindle D passes
out of the open end A' of the casing A through a suitable cover K provided with a
packing gland K' by which this end of the casing A can be tightly closed and on
the end of the spindle D outside the casing A may be fitted a finger L which can point
to a graduated scale or other like indicia on the face of the cover K to indicate and
shew in what position the valve E at the time is and how far if at all it has been
raised off or has been placed off its seat at the mouth of the truncated cone B and
therefore to what extent the annular orifice therearound has been opened or
closed.
Another aperture M also provided with a collar is made in the casing A near to
the open end A thereof through which aperture M passes another spindle N at
right angles or thereabouts with the spindle D herein before described a packing
gland M being provided by which the aperture M can be tightly closed and the
inner end of the spindle N engages the spindle D and can cause the same to rotate
on its axis as and when the spindle N is rotated on its axis by and through any
suitable and ordinary or other means and devices such for example as a worm and
screw or a cogwheel and ratchet or as is very and extremely convenient and as is
shewn in Figure 1 two spur wheels. In this case the one spur wheel P is secured
on the inner end of the spindle N while the other spur wheel P¹ is loosely mounted
round and on the spindle D which in this place is made of a square section as shewn
at D' or is otherwise so formed or fitted in any usual or other manner that while
the rotation of the wheel P1 will ensure the rotation on its axis of the spindle D
this spindle D will be free to slide lengthwise or longitudinally in the preferably
somewhat elongated boss of this wheel P' as obviously is necessary to operate the
valve E and to open and close the annular orifice therearound and these spur
wheels P and P are preferably of the same diameters so that one complete rotation
on its axis of the spindle N will produce one complete rotation on its axis of the
spindle D. To operate and rotate the spindle N a separate and removable handle R
is preferably provided the shank whereof may be as long as may be convenient in
each particular case and the end of the spindle N may be made of a square section
as shewn at N' whereover a socket R¹ in the end of the handle R can be engaged
or these respective connecting parts thereof can be otherwise so formed and fitted
in any usual or other manner that the rotation or actuation of the handle R will

page_text: ensure the rotation on its axis of the spindle N and this removable handle R will
or obviously by removal may be kept quite cool whatever may be the heat of the
steam or gases that passes or pass through this nozzle or of the place in which the
same is placed. At the same time whensoever it may be desired so to do an
handle may be rigidly and irremovably connected to or fitted on or made with the
spindle N.
It may sometimes be advisable as for example when this nozzle is placed inside
a pipe or under a furnace that an indicator should be provided in full view outside
the same either in lieu of or in supplement of the indicator herein before described
at the rear end of the casing and in Figure 3 is shewn a method of effecting this
object. The finger L is fitted on the spindle N outside of all and a ring T with a
graduated scale or other like indicia is provided on the outer side or surface of the
pipe or other apparatus wherein the nozzle has been placed or elsewhere in full
view as may be appropriate in each particular case and the finger I can point to
the same in the manner and for the purpose herein before described and declared
but in this case it is obvious that the spur wheels P and Peither must be of the
same diameters or must have their diameters proportioned to each other in a
certain predetermined manner and due allowance made therefor on the ring so that
true and correct indications may be given.
Again it may sometimes be preferable to fit the finger on the shank of the
separate and removable handle in a similar manner and for the same purpose or
the handle itself whether removable or irremovable may be so constructed and
formed in any suitable and usual or other manner as to constitute and be or act as
the finger and in each case the ring would be complementarily placed or provided
to act in conjunction with the finger in manner hereinbefore described and when
the handle is removable the respective connecting parts of the handle and of the
spindle must be so constructed or fitted that the handle can be engaged on or in or
with the end of the spindle in one position only so that true and correct indications
may be given.
In Figure 1 the handle is shewn as being in a line at right angles with the line
of the spindle of the valve and of its lengthwise or longitudinal movement and it
may sometimes be desirable that the handle should be in some other relative
position and lie in some other relative direction and this evidently can be effected
in many various and ordinary ways. For example the spindle N can be placed in
some other position and lie in some other direction in respect of the spindle D the
aperture M being in all cases formed and arranged accordingly or an intermediate
spindle or intermediate spindles may be interposed between the spindle N and the
handle being provided with spur wheels or other suitable gearing whereby all the
spindles may together be rotated on their axes by the handle as is necessary.
Furthermore it may sometimes be advantageous that the handle should be
immediately and directly connected with the spindle D instead of being connected
therewith through the spindle N in manner as is hereinbefore described and this
can be effected in a similar manner and no further description or explanation can
be needed in which case likewise the indicator can be fitted and provided in manner
aforesaid.
We may state that we consider the exact and precise arrangements and methods
of construction and fitment herein before described and shewn in the accompanying
drawing to be extremely convenient and suitable and efficient but obviously we do
not limit ourselves exactly and precisely thereto for each and every part of this
our nozzle may be made of such a shape and in such a style and may be fitted and
arranged in the nozzle and to the other parts thereof in such a manner as may be
expedient or desirable or necessary in each particular case.
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
claim is
1. In a nozzle a casing A having a truncated conical end B and an entrance

page_text: aperture C near thereto a longitudinal spindle D provided with a male screw
thread in the casing A a diaphragm F and a bearing H provided with a female
screw thread round the spindle D and a conical valve E on the end of the
spindle D which can close the mouth of the truncated cone B in combination with
another spindle N means such as the spur wheels P and P' to cause the spindles N
and D together to rotate on their axes a separate or other handle R to rotate one
of the spindles N or D and a finger L on one of the aforesaid rotating parts
provided with a graduated scale or the like substantially as and for the purposes
herein before described and declared.
2. The arrangement and combination of parts and appliances constituting this
our nozzle for steam or compressed air or gas substantially as herein before
described and shewn in the accompanying drawing.
