IMPROVEMENTS IN GAS REGU- LATING AND SAVING APPARATUS
Year: 1876

page_text: LETTERS PATENT to Peter Sieh and Theodore Schwarz, Engineers, in the City
of Hamburg, Germany, for the Invention of "IMPROVEMENTS IN GAS REGU-
LATING AND SAVING APPARATUS."
Sealed the 16th February 1877, and dated the 28th August 1876.
PROVISIONAL SPECIFICATION left by the said Poter Sieh and Theodore
Schwarz at the Office of the Commissioners of Patents on the 28th August
1876.
PETER SIEH and THEODORE SCHWARZ, Engineers, in the City of Hamburg,
Germany. "IMPROVEMENTS IN GAS REGULATING AND SAVING APPARATUS,”
This apparatus consists of a metal case, which we prefer to give a spherical form.
In about the middle of this case an air-tight partition made of flexible material
(either prepared leather or other suitable substance) divides the case into two com-
partments. At the lower end of the spherical case a metal tube is connected to it
at right angles. This tube is likewise divided into two compartments by a hori-
zontal partition made of sheet metal, of which the lower one is connected to the
inlet pipe of the gas The gas passes from this compartment through a valve into
the under partition of the spherical case, from which it escapes through an opening
into the upper division of the metal tube leading to the gas pipes and burners.
The pressure of the gas in the spherical case is regulated by the lifting or lowering
of the flexible partition, and as this partition is in connection with the admission
valve the opening of the same is either diminished or enlarged when the pressure
either rises above or falls below its normal state. From the top of the spherical
case the resistance of the flexible partition can be regulated by means of weights,
which can be placed on the upper surface of the same. In this manner the pressure
of the gas is regulated within the spherical case, and in consequence a uniform flow
of gas through the outlet pipe is attained, and considerable saving of gas at the
burners effected.

page_text: This apparatus consists of a metal case, which we prefer to give a spherical form.
In about the middle of this case an air-tight partition made of flexible material
(either prepared leather or other suitable substance) divides the case into two
compartiments. At the lower end of the spherical case a metal tube is connected to
it at right angles This tube is likewise divided into two compartments by a hori-
zontal partition made of sheet metal, of which the lower one is connected to the
inlet pipe of the gas. The gas passes from this compartment through a valve into
the unde partition of the spherical case, from which it escapes through an opening
into the upper division of the metal tube leading to the gas pipes and burners.
The pressure of the gas in the spherical case is regulated by the lifting or lowering
of the flexible partition, and as this partition is in connection with the admission
valve the opening of the same is either diminished or enlarged when the pressure
either rises above or falls below its normal state From the top of the spherical
case the resistance of the flexible partition can be regulated by means of weights,
which can be placed on the upper surface of the same.
Figure 1 of the accompanying Diawings represents the apparatus in section;
Figure 2 is a front view; and Figure 3, a ground plan of same.
The gas passes through the pipe a into the horizontal tube A, which is divided in
a horizontal direction into two compartments by the partition wall b. The sphere
or shell B, made of sheet metal, is connected to the tube A, and is likewise divided
into two parts by means of the flexible diaphragm C, made of leather or other
suitable material. The gas enters the lower compartment of the sphere B from"
around the valve D, which is in connection with the diaphragm C by means of a
rod e.
From the sphere or vessel B the gas passes through an opening into the
upper compartment of the tube A, which has a partition b, and thence through the
passage G to the burners. The regulation of pressure takes place within the sphere
or ball B as the diaphragm C is lifted by the pressure of the gas, and thereby regu-
lates the closing of the valve D, so that when the pressure is too great the valve D
becomes nearly closed, and thus reduces the admission. The reverse takes place
when the pressure is lower than the normal, as the valve D at once opens a little
more, and allows a larger quantity of gas to flow through to the burners
resistance of the diaphragm C can be adjusted by means of weights placed on the
top of it, according to the normal pressure required. A perfectly equal flow of gas
to the burners takes place, thus causing a considerable saving in the consumption.
By means of the screw plug i impurities that may collect within the sphere can
be removed.
The
The vessel B we have shown of spherical form, but vessels otherwise formed may
be used.
Having now described the nature of our said Invention, and in what manner the
same is to be performed, we declare that we claim the special combination of
parts arranged as described and shown in the annexed Drawings, and forming an
apparatus for regulating the flow of gas to burners and also for preventing waste of
gas, as set forth.
In witness whereof, we, the said Peter Sieh and Theodore Schwarz, have herc-
unto set our hands and seals, this Sixteenth day of February, One thousand
aight hundred and cawantv.
