Complete Specification Left, 3rd June, 1889-Accepted, 6th July, 1889
The cover c is connected with the gas-inlet tuber by means of a well-known,
common ball-joint k, and the cover d is secured to the gas-tube », which feeds the
lamp.
In the casing G I provide two or more sieve plates pp for the purpose of retaining
and sucking up the impurities of the gas.
In the
Under these sieves a wall g is arranged, provided with the hole g².
space G of the casing G is fitted a spring a with a plate a¹, to which a bell g is
screwed on the one side and the stopper A at the other side. This stopper A fits into
the opening of the valve-seat-plate h, arranged in the bottom or cover d of the
casing G. By means of the spring a, having the two closing mechanisms and A.
the regulating of the gas-passage is effected. The vibration of this arm a a¹ is limited
from below by an adjustable screw s arranged at a suitable place in the cover d.
The stopper A is hinged to the spring lever a a' by means of screw t.
position of repose the bell g closes by the force of the spring a the outlet passage g³ of
the plate gl; but when the gas-burner, attached to the gas-tube is opened, the
pressure of the gas lifts the bell g off the opening g².
In the
If my means of the adjustable screw the closing organ A is adjusted to a certain
section from below, the pressure of the gas passing through the regulator-case, forces
the spring lever a a', as well as the pending stopper A, attached to it, down, so that
the gases may pass in beside the stopper A through the adjusted section of the
passage and feed the lamp.
The section of the passage diminishes automatically, when the pressure of the gas
increases, on account of the spring lever a a', bearing the stopper A, being pressed
down; (see fig. 2.). But when the pressure of the gas becomes lower than the usual
pressure, the force of the spring a lifts the stopper A, and the section of the passage h¹
increases respectively, so that in spite of the lower pressure of the gas, nearly the same
quantity of gas is allowed to pass.
This decreased or lowered pressure of the gas, respectively the fluctuations of the
pressure is consequently of no influence on the flames, connected with the conduit ¹.
The above described regulating device secures always a suitable section of the
passage, and this section may be adjusted from the outside as required; my apparatus
secures further a perfectly quiet burning of the flammes under all circumstances.

conveniently lowered, and the regulating mechanism be freed from the casing G
without disengaging the apparatus, and without removing the lamp.

The above described regulating device secures always a suitable section of the
passage, and this section may be adjusted from the outside as required. My apparatus
secures further a perfectly quiet turning of the flames under all circumstances.
By the nse of the screw bolts the cover d with the lamp attached to it may be
conveniently lowered and the regulating mechanism be freed from the casing G with-
out disengaging the apparatus and without removing the lamp.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what
claim is:
1.) In gas regulators: the combination of a casing G provided with one or more
siove-plates p p with a spring stopper A actuated by the varying pressure of the gas,
for the purpose and in the manner, substantially as described.
2.) In gas regulators: the combination of a casing G having sieve-plates with a
spring a carrying an inverted bell g, which closes the opening for the gas on its top
side and a stopper A on its under side, for the purpose and in the manner, substan-
tially as described.
3.) In gas regulators: the combination of a casing G, spring stopper A and bell g,
with a regulating screw 8, for the purpose and in the manner substantially as
described.
4.) In gas regulators: the combination of a casing G, moveable covers c and d,
screws bb with a spring closing valve g and spring closing stopper or valve A and
regulating screw s, for the purpose and in the manner, substantially as described.
