Improvements in Electric Apparatus for Igniting and Extinguishing
Gas Jets Simultaneously from a Distance.
I, OSOAR VON MORSTEIN of Nollendorfstr., Berlin, Germany, Engineer, 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:
This invention has for object to provide improved and economical means for igniting
and extinguishing any convenient number of gas jets with the use of only one
conductor and one contact.
For this purpose an electro magnetic gas closure opener common to all the jets
is applied at any convenient part of the common gas supply pipe but the ignition of
the gas jets is effected by secondary induction currents.
The drawings shew diagrammatically various ways of carrying out the invention.
The electric opening and shutting off of the gas pipe R is effected by utilising
said pipe in a known manner or by means of two different electro magnets or two
different conductors. In Fig. 1 a second electro magnet Z for closing the gag
pipe R is shewn in dotted lines with a second conductor. The gas pipe R may
serve as the one conductor for the battery curront as well as for the secondary
currents as is supposed to be the case in all the figures. H is the closure, n cock
for instance, of the gas pipe. E the cock-opening electro magnet. P the primary
bobbin. S the secondary bobbin. A the arinature of the electro-magnet. a, b, the
circuit breaking arrangement for the curront. K the tin foil collector. B the
battery and C the contact. The gas cock opener E and the inductor are in
the most intimate connection with each other, being sot in activity both by the
same battery current, the same conductor and the same contact.
The same
current namely which excites the opening electro magnet produces in the secondary
bobbin S the secondary current required for the ignition of the gas jets by means of
intermittently springing sparks. This may be accomplished either by employing the
opening electro magnet E itself as a primary bobbin P and placing the secondary
bobbin directly over the same (which however I do not claim as it is not practically
available) or, according to this invention and out of regard for constructive and
economical advantages, by in a manner practically separating a portion of the opening
electro magnet and employing this portion as a primary bobbin so that then the
primary bobbin P of the inductor and the opening electro magnet E will appear as in
Fig. 2 as connected behind one another but as in Fig. 3 in parallel. This

page_text: "connection of the primary bobbin P of the inductor may also be effected auto-
matically after opening of tho gas closure by means of a simple modification of
construction hereinafter described of the gas closure opener (Fig. 4-parts A, B).
There is then the advantage that larger portions of the current come into use for
actuating both parts.
The circuit breaking arrangement is designed in the munner that the battery
current at the moment when it is interrupted in the opening electro magnet shall go
through the primary hobbin P and inversely.
Fig. 6 parts A, B shew a circuit breaking arrangement in which the spring
contact. piece a after it has been lifted from the firm contact piece comes to bear
against a third contact piece c and thus conducts the current, which in the bobbin Pl
is broken, through the bobbin P'. In a manuer analogous to that here given for
two primary bobbins P, P, the arrangement may also be used for conducting the
current alternately through the opening electro magnet E and the primary
bobbin P.
As the secondary currents for the ignition of a large number of jets must be
of comparatively high tension and that therefore owing to the difficulty of the
insulated passage of the same to and especially at the burners, a limit would have
to be drawn, it is advantageous to construct the secondary bobbin S in the form of
a number of small bobbins each of low tension and used for the ignition of a sumall
number of jets. This may be accomplished by placing small bobbins over, or
against one another, or by a corresponding division of the winding of large hobbins
(Fig. 5). If the secondary windings are divided upon several primary bobbins the
current interrupting arrangement may be designed so that the battory current is
conducted alternately through two groups of the primary bobbins (Fig. 6 parts A, B).
For the purpose of the supplementary connection referred to, of the primary
bobbin P (Figs. 4 parts A, B) there is applied to the plug or moving part of the
cock H a contact piece upon which the spring e leading to the electro
magnet E slides until the cock H is opened, then however the contact piece h lays
itself against the spring p which will now conduct the current through the primary
bobbin P.
The carrying out and arrangement of the whole device may
modified in regard to details.

tion and in what manner the same is to be performed, I declare that what I
claim is :-

closure opener E with a spark inductor P in the manner that both are set in activity
by the same current and through the same conductor and the same contact, and so
that the automatic close circuiting of the inductor P takes place after opening of the
gas pipo closure H, substantially as described and illustrated in the various figures of
the accompanying drawing with the exception of Fig. 1.
