Improvements in Apparatus for Controlling or Regulating the
Supply of Gas to Burners.
I, SEVERIN SENATOR of Wilhelmstrasse 3* Berlin, German Empire, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
Gas pressure controlling or regulating apparatus as heretofore constructed
though effecting some economy in the consumption of gas do not properly regulate
the flames, as the gas has not sufficient force to overcome the weight of the valve,
the friction of the parts and the pressure of the air and lift the valve to an amount
varying according to the number of the burners in use and to finally close when
none of the burners are in use. Thus when only some of the burners have been in
use, the pressure of the gas not being properly regulated the gas passing through
the burners has not been completely burnt. In order to obviate this inconvenience
the lifting membrane or diaphragm is according to this invention supported from
outside.

Fig. 1 is a plan of controlling or regulating apparatus according to my invention;
Fig. 2 a side elevation thereof;
Fig. 3 a sectional view, showing the valve fully open; and
Fig. 4 a similar view, but showing the valve closed.
The valve rod A is extended and its upper extremity formed as a rack B. The
latter meshes with a toothed wheel C fixed upon a spindle D mounted by means of
conical or other bearings in the frame E. Upon the spindle D is keyed a pulley F
which is attached to a flexible band G in such a manner that when the point of
attachment g is situated on the highest point of the pulley F an equal length of the
band hangs on each side of the pulley. Upon the band G are fixed weights a¹ a² a²
a a a b 6 88 64 b³ bo. A guiding roller H secures the engagement of the rack B
and the toothed wheel C. On one side of the frame E is fixed a pin or bolt a
which allows the pulley F which is provided with two projections 6* 68 to rotate
sufficiently for the point g to move from the position shown in Fig. 3 to that
shown in Fig. 4 or vice versa. In order to render it possible to maintain the valve
in its open or closed position the bolt a is capable of adjustment longitudinally and
the plate of the pulley F carrying the projections 67 68 is provided with openings or
holes c¹ c², into which the pointed end of the arresting bolt a takes. By putting
the bolt a into the hole c¹ the pulley F is maintained in the position shown in
Fig. 3 the gearing holding the valve V in an opened position; by putting the
bolt a into the hole of the pulley F the valve V is maintained in a closed
position, as shown in Fig. 4.
The operation of the apparatus is as follows:-
The gas enters at I, and lifts the membrane K together with the rack B, rotating
the toothed wheel C and at the same time the pulley F until the point g occupies
a position directly above the spindle. In this position the weights attached to the
band G balance but as soon as the membrane is raised or depressed according to
whether the pressure of gas increases or decreases either the weights a¹ etc. or b
etc. come into action, and as the weights act upon the shaft D with the radius of
the pulley F as a lever arm, the operation of the membrane is aided and the
regulation facilitated.
The apparatus is mounted upon the cover L of the regulator, and said cover L

put upon the cup M, as in the usual membrane gas regulators.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Controlling or Regulating the
Supply of Gas to Burners.
I, SEVERIN SENATOR, of Wilhelmstrasse 3ª Berlin, German Empire, Manu-
facturer, 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 :-
Gas pressure controlling or regulating apparatus as heretofore constructed though
effecting some economy in the consumption of gas, do not properly regulate the
flames, as the gas has not sufficient force to overcome the weight of the valve, the
friction of the parts and the pressure of the air and lift the valve to an amount
varying according to the number of the burners in use and to finally close when
none of the burners are in use. Thus when only some of the burners have been in
use, the pressure of the gas not being properly regulated the gas passing through
the burners has not been completely burnt. In order to obviate this inconvenience
the lifting membrane or diaphragm is according to this invention supported from
outside.
.
In the drawings filed with my Provisional Specification,
Fig. 1 is a plan of controlling or regulating apparatus according to my invention;
and
Fig. 2 a side elevation thereof;
Fig. 3 a sectional view, showing the valve fully open; and
Fig. 4 a similar view, but showing the valve closed.
The valve rod A is extended and its upper extremity formed as a rack B. The
latter meshes with a toothed wheel C fixed upon a spindle D, mounted by means of
conical or other bearings in the frame E. Upon the spindle D is keyed a pulley F-
to which is attached a Hexible band, chain or the like G (hereinafter referred' to
as a band) in such a manner that when the point of attachment g is situated on the
highest point of the pulley F an equal length of the band hangs on each side of
the pulley. Upon the band G are fixed weights a¹ a² a³ a¹ aª a² b² b² bª b¹ bª bº. A
guiding roller H secures the engagement of the rack B and the toothed wheel C.
On one side of the frame E is fixed a pin or bolt a which allows the pulley F
which is provided with two projections 67 68 to rotate sufficiently for the point g to
move from the position shown in Fig. 3 to that shown in Fig. 4 or vice versa.
order to render it possible to maintain the valve in its open or closed position the
bolt a is capable of adjustment longitudinally and the plate of the pulley F carrying,
the projections 67 68 is provided with openings or holes c¹ c², into which the pointed
end of the arresting bolt a takes. By putting the bolt a into the hole c¹ the
pulley F is maintained in the position shown in Fig. 3 the gearing, holding the
valve V in an opened position; by putting the bolt a into the hole o² of the pulley, F
the valve V is maintained in a closed position as shown in Fig. 4.
The operation of the apparatus is as follows:-
In
The gas enters at I and lifts the membrane K together with the rack B, rotating
the toothed wheel C and at the same time the pulley F until the point g occupies a..
position directly above the spindle D. In this position the weights attached to
the band G balance but as soon as the membrane is raised or depressed according
to whether the pressure of gas increases or decreases either the weights a¹ etc. or
etc. come into action, and as the weights act upon the shaft D with the radius of

page_text: the pulley F as a lever arm, the operation of the membrane is aided and the
regulation facilitated.
The apparatus is mounted upon the cover L of the regulator, and said cover L
may be made of two parts, so that one part may be removed and adjusting weights
put upon the cup M, as in the usual membrane gas regulators.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Apparatus for controlling or regulating the supply of gas to burners having a
membrane or diaphragm whose operation is assisted by weights on a flexible band,
chain or the like that passes over and is attached to a pulley actuated by the
pressure of the gas the arrangement being such that the weights balance under a
normal pressure, while when the pulley is rotated by the raising or depression of
the membrane the weights over balance on one side or the other and accelerate the
regulation substantially as described.
2. In a gas pressure regulator of the kind referred to in Claim 1 the pulley F
mounted upon an axle D carrying a toothed wheel C, which is rotated by the
rack B attached to the valve-rod A, said rod being actuated by the membrane
substantially as described for the purposes specified.
3. Apparatus for controlling or regulating the supply of gas to burners con-
structed and operating substantially as hereinbefore described with reference to the
accompanying drawings.
