PROVISIONAL SPECIFICATION.
Improvements in Bye-pass Gas Burners.
1, MORTIMER PETERSON, of Hamngatan No. 32, Stockholm, Sweden, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to bye-pass gas burners, and it has for object to diminish
the supply of gas to the pilot jet or auxiliary flame when the gas issuing from the
main burner is lighted. To this end the gas conduit to the auxiliary burner is
provided with a cock or valve combined with the ordinary cock in such a manner
that the former cock or valve is almost shut when opening the ordinary cock and is
opened to its normal size when closing the ordinary cock.
In an arrangement of this kind the ordinary cock is lengthened and provided
with an additional passage opening into the common gas supply and into the
conduit leading to the auxiliary burner, the said passage being arranged in the
plug in relation to the main passage for the ordinary burner in such a manner
that in operating the cock in the usual way, the above mentioned object is
attained.

I, MORTIMER PETERSON, of Hamngatan No. 32, Stockholm, Sweden, Engineer,
do hereby declare the nature of this invention and in what manner the same
is to be performed to be described and ascertained in and by the following
statement:-
This invention relates to bye-pass gas burners, and it has for object to diminish
the supply of gas to the pilot jet or auxiliary flame when the gas issuing from the
main burner is lighted. To this end the gas conduit to the auxiliary burner is
provided with a cock or valve combined with the ordinary cock in such a manner
that the former cock or valve is almost shut when opening the ordinary cock and is
opened to its normal size when closing the ordinary cock.
In an arrangement of this kind the ordinary cock is lengthened and provided
with an additional passage opening into the common gas supply and into the
conduit leading to the auxiliary burner, the said passage being arranged in the
plug in relation to the main passage for the ordinary burner in such a manner
that in operating the cock in the usual way, the above mentioned object is
attained.
In the accompanying drawing there is illustrated an arrangement according to
this invention in which a cock which controls both the main gas passage and the
bye-pass is operated by electromagnets.
Figs. 1 and 2 being elevations at right angles to each other and partly in section
of the lower part of the burner;

page_text: Figs. 3 and 4 being part sections (to an enlarged scale) through the bye-pass and
respectively showing the cock in the position in which the main gas conduit is
closed and the bye-pass or conduit leading to the auxiliary burner wide open, and
vice versa; and
Fig. 5 a plan of the plug of the cock in the position shown in Fig. 4.
a is the plug which, in the example shewn, is connected to an armature b (shown
in its middle position in Figs. 1 and 2), operated in any known manner by electro-
magnets c, c. d is the main gas conduit and e the conduit leading to the auxiliary
burner. The plug a is formed with a passage f that corresponds to the conduit d
and also, with a passage g that corresponds to the conduit e, said passages and g
being so relatively located that when the conduit fis open the other conduit g is
almost closed and vice versu, (see Figs. 3 and 4).
As mentioned above, the cock is so arranged as not to entirely close the conduit
to the auxiliary burner when the conduit to the main burner is open, and for this
purpose the plug is formed with two narrow channels leading from the ends of
the passage g (see also Fig. 5), which channels, when the cock is in the position in
which the conduit to the auxiliary burner is closed, allow a small quantity of gas to
pass, as indicated by the arrow in Fig. 4.
The same purpose may, however, be attained by locating the narrow channels in
the shell or body of the cock, instead of in the plug.
If a separate cock is used to control the conduit to the auxiliary burner, said
cock must be arranged in such a manner that it cannot, when used, entirely close
the couduit, but must leave a passage or passages through the plug, or, it may be,
in the body of the cock, through which a small quantity of gas may pass when
the cock is in such a position that gas is passing freely through the main
conduit.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what 1
claim.is -
1. In a bye-pass gas burner combining with the cock through which gas passes
to the main burner a cock through which gas passes to the auxiliary burner the
arrangement being such that when the first named cock is opened the passage
through the other cock will be nearly closed and that when said first named cock
is closed the passage through the other cock will be fully opened substantially as
described.
2. My improved bye-pass burner constructed and operating substantially as
shewn in and described with reference to the annexed drawings.
Dated this 27th day of August 1896.
