BURNERS."
[A communication by Albert Behl, Manufacturer, of Quedlinburg,
in Prussia, Germany.]
The regulator is composed of,-
1. The bottom part a provided with threads for screwing it, its top flange r
serving as seat to the valve c when at rest.
2. The top part C screwed to the bottom part a being provided internally with
the valve seat & containing the valve c and receiving above it the burner.
3. The valve c and the valve seat d.
The valve c consists of a tube of thin sheet-iron upon which a disc is soldered or
brazed.
The inner space of the regulator is put in communication with the gas flow and
the burner by its openings.
Fig. 1 shows the valve c provided at its bottom with a slide 8 in order to be able
to regulate the gas flow to the burner, according to requirements.
Fig. 2 shows the valve closed at the bottom, and instead of the adjustable slide
the regulating screw is inserted in the circuit channel g, serving for the same
purpose. The difference in this arrangement is only to provide means that the
regulation can take place or not, as desirable, from the outside.

page_text: The valve seat d is a short cylinder provided with a set-off and with side
openings near it. It is entirely bored out in its longitudinal direction so that it
can be better manufactured and cleaned, while it is closed at its top by means of a
small inserted cap k.
The flow of the gas to the corresponding burner is regulated by means of the
adjustable slide s in Fig. 1, or the set screw f, Fig. 2; that is to say, the flow
becomes so much reduced that the larger section of the burner in the space above
the disc of the valve c produces such a great relief of pressure while the flame is
burning that the valve c through the greater pressure underneath its disc becomes
lifted. The valve c being consequently suspended, limits, through its position, the
outflow of the gas.
It is regulated in such a manner that the above-mentioned
difference of pressure which depends upon the two invariable factors, namely, the
weight and the pressure surfaces of the valve c, are kept constant.
There are also other regulators constructed on the same above-named principle,
but its improvement consists in the use of a valve which allows the gas to flow out
sideways, while also its pressure surfaces at the top rest constant at each level till
the end, allowing hereby a most complete and correct regulation, which is not the
case in other constructions. Its internal arrangement is very simple and its manu-
facture very cheap.
In the arrangements designed till now the pressure surface at the top of the valve
diminishes at great pressure, partly by introducing a covering or closing point into
the space where the gas flows out, as it is the case in the construction by Giraud,
partly by means of edge surfaces, which close the space by approaching the sides,
placed above, as it is the case in the construction by Bablon. There the gas flows
out between the surfaces and does not receive the full pressure from the inner part
of the regulator but the low pressure of the gas which flows out. The consequences
are irregularities in the consumption, which the present design, as above described
and represented in the Drawings, will avoid.
Having thus described the nature of the Invention, and the manner of performing
the same, it will be understood that the improvements upon which the claims are
principally based consists,―
1. In the self-regulating gas burner provided with a special valve adjusting piece
or seat d, whereby the valve c being lifted according to the different pressures of the
gas to different heights, this adjusting piece allows the whole top surface of
the valve to be invariably presented to the inner pressure of the gas, to the
effect and in the manner as before described, and as represented in the adjoined
Drawings.
2. In the self-regulating gas burner provided with the regulating or set screw f
in order to adjust the consumption of the gas from outside.
3. In the self-regulating gas burner, composed as above described, and as
represented in the adjoined Drawing.

The regulator is composed of :-
1. The bottom part a provided with threads for screwing it, its top flange 'r
serving as seat to the valve c when at rest.
2. The top part C screwed to the bottom part a, being provided internally with
the valve seat d containing the valve c and receiving above it the burner.
3. The valve c and the valve seat d.
The valve c consists of a tube of thin sheet iron upon which a disc is soldered or
brazed.
The inner space of the regulator is put in communication with the gas flow and
the burner by its openings.
Fig. 1 shows the valve c provided at its bottom with a slide s in order to be able
to regulate the gas flow to the burner, according to requirements.
Fig. 2 shows the valve closed at the bottom, and instead of the adjustable slide
the regulating screw f is inserted in the circuit channel g, serving for the same
purpose. The difference in this arrangement is only to provide means that the
regulation can take place or not, as desirable, from the outside.
The valve seat & is a short cylinder provided with a set-off and with side
openings near it. It is entirely bored out in its longitudinal direction so that it can
be better manufactured and cleaned, while it is closed at its top by means of a
small inserted cap k.
The flow of the gas to the corresponding burner is regulated by means of the
adjustable slide 8 in Fig. 1, or the set screw f, Fig. 2; that is to say, the flow
becomes so much reduced that the larger section of the burner in the space above
the disc of the valve c produces such a great relief of pressure while the flame is
burning, that the valve c through the greater pressure underneath its disc becomes
lifted. The valve c being consequently suspended limits, through its position, the
outflow of the gas. It is regulated in such a nanner that the above-mentioned
difference of pressure, which depends upon the two invariable factors, namely, the
weight and the pressure surfaces of the valve c, are kept constant.
There are also other regulators constructed on the same above-named principle,
but its improvement consists substantially in the use of a valve which allows the
gas to flow out sideways, while also its pressure surfaces at the top rest constant at
each level till the end, allowing hereby a most complete and correct regulation,
which is not the case in other constructions. Its internal arrangement is very
simple, and its manufacture very cheap.
In the arrangements designed till now the pressure surface at the top of the valve
diminishes at great pressure, partly by introducing a covering or closing point into
the space where the gas flows out, as it is the case in the construction by Giraud,
partly by means of edge surfaces, which close the space by approaching the sides,
placed above, as it is the case in the construction by Bablon. There the gas flows
out between the surfaces and does not receive the full pressure from the inner part
of the regulator, but the low pressure of the gas which flows out. The consequences
are irregularities in the consumption, which the present design, as above described
and represented in the adjoined Drawing, will avoid.
Having thus herein described the nature of the Invention, and the manner of
performing the same, it will be understood that the improvements upon which the
claims are principally based consist,-
1. In the self-regulating gas burner provided with a special valve-adjusting piece
