Year: 1869

page_text: LETTERS PATENT to. James' Webster, of Birmingham, in the County-
of Warwick, Engincer, for the Invention of "A NEW OR IMPROVED.
NOZZLE FOR BLOWING AIR, STEAM, WATER, OR OTHER LIQUIDS AND GASES,
AND BLOWING, DRAWING, MIXING, AND FORCING FLUIDS AND VAPOURS."
Scaled the 1st March 1870, and dated the 4th September 1869.
PROVISIONAL SPECIFICATION left by the said James Webster at the
Office of the Commissioners of Patents, with his Petition, on the
4th September 1869.
I, JAMES WEBSTER, of Birmingham, in the County of Warwick,
Engineer, do hereby declare the nature of the said Invention for "A.
NEW OR IMPROVED NOZZLE FOR BLOWING AIR, STEAM, WATER, OR OTHER LIQUIDS
AND GASES, AND BLOWING, DRAWING, MIXING, AND FORCING FLUIDS AND VAPOURS,".
to be as follows, that is to say-
The nozzle which constitutes this Invention is intended for various.
purposes, and consists of two or more truncated cones placed one behind
or within or partially within the other, their relative position being

page_text: adjustable, and their axes common to each other, so that their con-
fluence and respective points of discharge may be in a right line.
The object of the new or improved form is to cause different gases or
vapours and liquids to be thereby simultaneously blown and drawn from
different sources or containers, and to be mixed and discharged there-
from in any required proportions at the confluence or common point of
exit. The innermost cone I attach to the end of a pipe, upon which
pipe I place a tap or valve to regulate the volume of gas, vapour, or
liquid passing through it. At the base of this cone and round its outside
I form a flange, to which flange I screw or fix the base of the outer
cone, so as to obtain an adjusting air-tight joint. The outer cone is
somewhat longer internally than the inner one externally, so as to leave
a clear space between them when fitted together and adjusted. The
small ends of the cones are their points of discharge, and the point of
discharge of the outer cone is in advance of that of the inner one. The
diameter of the discharging orifice of the former or outer cone is greater
than that of the latter or inner one. The distance between their two.
ends or points of discharge must be regulated by their relative sizes; as
a general rule these may be determined, or. should be such that when the
line of the inner surface of the inner cone is produced it will bisect the
line of the inner surface of the outer cone at its extremity. In the
flange at the base of the two cones by which they are fixed together,
and equidistant from the axis of the cones and equidistant from each
other I form perforations to receive the ends of two or more pipes,
upon each of which pipes I also place taps or valves to regulate the
quantity of vapour or gas passing through the same respectively.
The operation of the nozzle is as follows:-Supposing it to be required
to draw water from one source by blowing steam from another, the
steam would be turned on through the inner cone and the ends of the
two pipes (attached to the flange before mentioned) inserted in the
water. Now upon opening the steam tap and the two water taps the
water would be drawn up and blown out at the point of discharge.
Supposing air and gases or vapours of different character are to be
blown and drawn the air may be blown through the centre cone, and
the gases will be drawn in as the water was drawn in in the case last
described.

filed by the said James Webster in the Great Seal Patent Office
'on the 4th March 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WEBSTER, of Birmingham, in the County of Warwick, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of September, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Webster, Her special licence
that I, the said James Webster, my exccutors, administrators, and
assigns, or such others as I, the said James Webster, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "A NEW OR
IMPROVED NOZZLE FOR BLOWING AIR, STEAM, WATER, OR OTHER LIQUIDS AND
GASES, AND BLOWING, DRAWING, MIXING, AND FORCING FLUIDS AND VAPOURS,'
upon the condition (amongst others) that I, the said James Webster,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
"
NOW KNOW YE, that I, the said James Webster, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement :-
The nozzle which constitutes this Invention is intended for various
purposes, and consists of two or more truncated cones placed one behind
or within or partially within the other, their relative positions being
adjustable, and their axes common to each other, so that their con-
fluence and respective points of discharge may be in a right line.

page_text: The object of the new or improved form is to cause different gases or
vapours and liquids to be thereby simultaneously blown and drawn from
different sources or containers, to be mixed and discharged therefrom in
any required proportion at the confluence or common point of exit. The
innermost cone I attach to the end of a pipe, upon which pipe I place à
tap or valve to regulate the volume of gas, vapour, or liquid passing
through it. At the base of this conc and round its outside I form a
flange, to which flange I screw or fix the base of the outer cone, so as
to obtain an adjusting air-tight joint. The outer cone is somewhat
longer internally than the inner one externally, so as to leave a clear
space between them when fitted together and adjusted. The small ends
of the cones are their points of discharge, and the point of discharge of
the outer cone is in advance of that of the inner one. The diameter of
the discharging orifice of the former or outer cone is greater than that of
the latter or inner cone. The distance between their two ends or points
of discharge must be regulated by their relative sizes; as a general rule
these may be determined, or should be such that when the line of the
inner surface of the inner cone is produced it will bisect the line of the
inner surface of the outer cone at its extremity. In the flange at the
base of the two cones by which they are fixed together, and equidistant
from the axis of the cones and equidistant from each other 1 form
perforations to receive the ends of two or more pipes, upon each of
which pipes I also place taps or valves to regulate the quantity of
vapour or gas passing through the same respectively.
The operation of the nozzle is as follows:-Supposing it be required
to draw and discharge water from one source by blowing, steam from
another, the steam would be turned on through the inner cone and the
ends of the two pipes attached to the flange before mentioned inserted
in the water. Now upon opening the steam tap and the two water taps
the water would be drawn up and blown out at the point of discharge.
Supposing air and gases or vapours of different character are to be
blown and drawn the air may be blown through the centre cone, and
the gases will be drawn in as the water was drawn in in the case last
described.
In the case of using gas through the centre cone and air through the
outer cone for heating purposes, brazing, cooking, and the like, instead
of fitting the outer cone with pipes just above described, simple per-
forations may be substituted for the admission of air, which will then be
ELS

page_text: drawn through the same. The result of this application of the improved
nozzle will be to obtain a more perfect combustion of the gas when
ignited and a greater amount of heat therefrom; the carbon will be thus
thoroughly consumed, and hydrogen or carbonic oxyde flame produced.
I claim the improved nozzle, formed and constructed substantially as
herein described.
In witness whereof, I, the said James Webster, have hereunto set
my hand and seal, this Second day of March, in the year of our
Lord One thousand eight hundred and seventy.
