PROVISIONAL SPECIFICATION left by the said George Beck and Philip
Syng Justice at the Office of the Commissioners of Patents on the 5th
November 1877.
GEORGE BECK, of No. 37, Devonshire Street, Queen's Square, and PHILIP SYNG
JUSTICE, of No. 27, Southampton Buildings, Chancery Lane, both in the County of
Middlesex. "IMPROVEMENTS IN NOZZLES FOR THE ESCAPE OF STEAM OR GASES
UNDER PRESSURE."
This Invention consists of an apparatus through which steam and gases under
pressure shall be made to pass in such a manner as to be emitted without the usual
roaring noise, and without any considerable increase of back pressure.
It may be also used as a means of sustaining an uniform and regular draught in
high-pressure engines, when applied as a nozzle to the exhaust pipes, if it be carried
into the smoke funnel for that purpose.
It consists in providing a suitable metallic chamber which shall be fitted with
small particles of glass, stone, metal, or other suitable materials, and preferably of a
spherical form, either solid or pierced with holes, and through which chamber and
its contents the steam and gases shall be made to pass before it escapes into the
open air.
The tortuous interstices by which the steam or gases must thus pass completely
breaks up the roaring noise usually made in its exit, and only a soft hissing noise
in board in its wees

page_text: By providing the area of outlet from the chamber of greater proportions than
the inlet area, the back pressure is at the same time avoided or reduced to a
minimum point.
SPECIFICATION. in pursuance of the conditions of the Letters Patent filed by
the said George Beck and Philip Syng Justice in the Great Seal Patent Office
on the 3rd May 1878.
GEORGE. BECK, of No. 37, Devonshire Street, Queen's Square, and PHILIP SYNG
JUSTICE, of No. 27, Southampton Buildings, Chancery Lane, both in the County of
Middlesex. "IMPROVEMENTS IN NOZZLES FOR THE ESCAPE OF STEAM OR GASES
UNDER PRESSURE."
This Invention consists of a nozzle or chamber of metal or other material
in which may be enclosed small particles of glass, stone, metal, or other suitable
material, preferably of a spherical form, either solid or pierced with holes like beads,
and varying in size and quantity according to the pressure and volume of the steam
or gases which are to pass through the same, the object being to permit the steam
or gases to pass freely through the interstices existing between these particles or
through the holes with which they may be pierced as they lie in the chamber or
nozzle, and by this minute subdivision of volume suppress the roaring noise
usually attending the escape of steam or gases when under pressure.
When such steam or gas is to-be used-to create an artificial draught in the smoke
funnels of locomotives or other high-pressure engines, this Invention may be advan-
tageously employed to equalize and sustain a more uniform draught than is usually
obtained, while at the same time it will subdue the ordinary "puffing" and "jerking"
of the exhaust steam, and thus prevent the shooting out from the smoke funnel
of cinders and live coals which are so often the cause of serious conflagrations...
These nozzles or chambers may also be attached with advantage to the end of
steam pipes when the same are carried into dyeing or scouring vats, and will
subdue the noisy vibrations usually attending the discharge of steam into the
contained liquid.
To more clearly illustrate this Invention, and the various forms in which it
may be utilized with advantage, reference is made to the annexed Drawings of
which,―
Fig. 1 shows a sectional elevation of one form in which this chamber or nozzle
may be manufactured, A being the inlet, and Z the outlet opening. Above:
the inlet opening is fixed a grating or pierced plate B, B, whilst at or near the
outlet is affixed a similar grating or pierced plate, care being taken that the per-
forations in these plates are of such size and shape as to prevent the contained
material from either passing through or closing the openings, the combined area of
which should greatly exceed that of the steam pipe. Confined between these plates
or gratings are beads or such other suitable material as may be desired, and through-
this material or mass of beads the steam or gas must pass before escaping to the
atmosphere..
..
When the volume of steam is not large and the pressure not over 20 to 40 pounds

page_text: per square inch, or the steam escape pipe does not exceed more than 3/4 to 1 inches
in diameter, chambers made of pipes 3 to 8 inches in diameter, and 8 to 12 inches
in length, and filled with glass beads of 1/8 to 3/8 inch diameter, will produce very
good results in quieting the noise, and will give only a minimum amount of back
pressure if arranged with proper regard to the area of the steam exit, care being
taken that only a proper quantity and right size beads or other materials be used,
according to the volume or pressure of the steam that it is intended to pass through
the chamber.
When quieting the noise is the main object to be attained, without regard to back
pressure, then the smaller size beads are the most effectual.
When utilizing this Invention upon steam ships, the form of chamber as shown at
Figure 2 may be used. This chamber may form the lower portion of the steam
escape pipe of a vessel, as shown at W, Figure 6, by simply cutting out a part of
the steam funnel, and substituting therefor the annular chamber as shown, the
central pipe of which E, E, is surmounted by a relief valve H with the same area as
the inlet opening I. This valve is not a necessity, but is placed as a precautionary
guard against the possibility of the beads or contained materials in the annular
chamber M, M, creating at any time too much back pressure by becoming foul. This
valve H is weighted to lift at one or two pounds greater pressure than is required
to enable the steam to escape freely through the material contained in the annular
chamber M, M, which in this case should be filled between the gratings o, o, 0, 0,
with the larger sized beads. The valve H is controlled by rod K, pawl p,
lever S, and weight L, and may at any time be lifted or opened by hand.
When preferred, a number of small nozzles or chambers, similar to Fig. 1,
may be used inside of a large chamber, and secured to a diaphragm plate, or
they may be fixed in the side of the pipe E, E, in Fig. 2, and good results can be
obtained from so using them.
Figure 3 represents this chamber applied in another manner to steam ships,
C, D, being a portion of the main steam supply pipe from the boilers to the engines;
G, a stop valve, and T, a safety valve and box connected by the chamber n and
pipe F with the steam escape funnel.
Figure 4 represents the quieting chamber U as it may be applied to portable road
and agricultural engines.
Fig. 5 represents the quieting chamber e as it may be applied to the
exhaust pipes of the cylinders R, R, in launches, pinnaces, torpedo, and other small
steam boats.
Having thus described the nature of the said Invention, and the manner in which
the same may be carried into effect, it may be observed that we do not confine
ourselves to these precise form or shape of the nozzles or chambers, as they may
be varied to suit certain circumstances; but what we claim and desire to secure by
Letters Patent, is,―
First. The construction and employment of metallic or other suitable nozzles or
chambers of any convenient form, examples of which are shewn on Drawings filled
or partially filled with loose particles of glass, stone, metal, or other suitable material,
for the purposes herein-before described or their evident equivalents.
In witness whereof, we, the said George Beck and Philip Syng Justice, have
hereunto set our hands and seals, this Third day of. May, in the year of our
Lord One thousand eight hundred and seventy-eight.
