Improvements in the Means of Regulating the Admission of Gas into
Incandescent and similar Burners.
1, RICHARD GÄBEL, 19, Pironischestrasse Dresden, Mechanical Engineer, do
hereby declare the nature of this invention and in what mannor the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The present invention concerns an arrangement by which the admission of gas
into the gas and air mixing chamber of burners of incandescent gas and similar
lamps is to be regulated. This arrangement consists, essentially, of a needle which
is joined to an adjustable slide, by means of which it may be introduced into, or
withdrawn from, a hole in the nozzle connecting the mixing chamber with the gas
supply pipe.
In the annexed drawing,
Fig. 1. shows the portion of the burner situated between the gas supply pipe and
the mixing chamber, with the regulating arrangement, in vertical section.
Fig. 2. shows a section through - in Fig. 1.
Fig. 3. shows the needle and slide, in elevation.
Fig. 4. shows a section through - in Fig. 1.
Fig. 5. shows a second form of execution of the arrangement for adjusting the
slide and needle.
Fig. 6. shows a section through y-y in Fig. 5.
Fig. 7. shows a further modification of the adjusting arrangement.
Fig. 8. shows a section through z-z in Fig. 7.
As will be seen from Figs. 1, 5 and 7, there is fixed to the upper part of the
body a of the nozzle, a little sieve & through which the gas entering from below,
passes into the gas and air mixing chamber arranged above the sieve. Underneath
this sieve a pin d terminating conically at its upper end, is fastened to an adjustable
slide c by means of "bridges" or counecting crosspieces e (Fig. 4) so that when
the slide is pushed up the point of the needle may enter the central orifice in the
sieva b.
The adjustment of the slide, in the arrangement shown in Fig. 1, is effected by
means of a regulating screw f, which is sorowed through the side of the body of the
nozzle and by means of a pin or stud g, arranged in the form of an excentric cam
at its anterior end, gears into a hole h (Fig. 3) provided in the side of the slide c.
The other end (situated outside the body of the nozzle) of the screw f, is provided
with a slot, iuto which a screwdriver may be inserted in order to turn the screw.
On the screw being turned in either direction, the slide c is moved up or down
by means of the excentric stud or cam g fitted to the screw, so that the needle d
will either close the central aperture in the sieve b, or else throw it open, thus
allowing the gas to escape upwards. By this means the quantity of gas admitted
into the mixing chamber can be regulated.
In the arrangement according to Fig. 5. the regulating screw is replaced by a
bolt n, cut out excentrically in the middle and pivoted in the body of the nozzle so
that its central part m passes through corresponding holes in the side of the slide.
Both ends of bolt n are provided with slots for turning the bolt (Fig. 6.) which
acts in the same way as the regulating screw f.
For the adjustment of the slide the modification characterised in Fig. 7. may also
be employed. In this case a regulating screw f' is carried through the bottom of
the body of the nozzle a, and conuected with the lower part of slide c, so that by

page_text: turning the screw in one or the other direction the slide c, and with it the needle d
can be raised or lowered.
The admission of gas from the supply pipe to the body of the nozzle a takes
place through an aperture C' provided in the body of the nozzle (Figs. 7 and 8).
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 I
claim is
1. In burners for incandescent gas light and similar lamps, the combination of
the nozzle connecting the gas supply pipe and the gas and air mixing chamber,
with an adjustable slide, aud a needle rigidly.fixed thereto and which is arranged
below the nozzle sieve and terminates in a conical point, together with means for
adjusting the slide, essentially as described and for the purpose stated.
2. In burners for incandescent light and similar lamps, the combination of the
nuzzle connecting the gas supply pipe and the gas nud air mixing chamber, with a
slide, a needle terminating in a conical point and which is situated below the sieve
of the nozzle and is attached to the slide,-and a regulating screw which gears into
the slide by means of an excentrically arranged pin or stud, essentially as described
and for the purpose stated.
3. In burners for incandescent gas light and similar lamps, the combination of
the nozzle connecting the gas and air mixing chamber with a slide, a needle fixed
to the slide and which is situated underneath the sieve of the nozzle and terininates
in a conical point, and a bolt pivoted in the body of the nozzle and extending with
its central part which is cut out in the form of an eccentric, through the side of the
slide, essentially as described and for the purpose stated.
4. In burners for incandescent gas light and similar lamps, the combination of
the nozzle connecting the gas supply pipe and the gas and air mixing chamber
with a slide, a needle fixed thereto and which terminates in a conical point and is
situated underneath the sieve of the nozzle, and a regulating screw, extending
through the bottom of the body of the nozzle and which is connected with the
lower part of the slide, essentially as described and for the purpose stated.
