PROVISIONAL SPECIFICATION.
I, ERIK ORLING, of 38, Hamugatan, Stockholm, Sweden, Mechanician, do
hereby declare the nature of this invention to be as follows:-
My invention relates to a modification in the construction of gas-lighters of the
auxiliary lighting tube pipe, its object being to render the same capable of igniting
the lighting flame of Auer-burners by means of electricity.
To this purpose a rod or lever supporting the movable contact is provided with
n slot at its lower end which engages with a cranked pin projecting from an arm
secured to the valve stem, so that the position of the rod or lever is changed by
the turning of the valve stem when opening or closing the gas supply. The
movable contact is attached to the upper end of said rod or lover, the latter being
pivoted at or about its centre to au upright or bracket secured to or forming an
integral part of a ring or washer placed upon the top of the burner tube and
secured in position by the screwing down of the burner cap. A stationary electric
contact is carried at the top of the aforesaid upright near the lighting pipe or
byepass outlet and is suitably insulated. The pussage connecting the interior of
the valve box with the lighting pipe or byepass is arranged and located in the said
valve box in such position relatively to the gas conduit pipe that on turning the
valve stem the gas escapes first through the lighting pipe or byepass then through
both the lighting pipe and the main pipe and finally, on completely turning the
valve, that is to say when the valve is fully open, gas can only escape into the main
pipe direct from the conduit. The necessity for the lighting pipe or byepass to be
continually alight is thus entirely obviated.
The operation of my invention is as follows:-When the gas valve is closed the
slotted contact lever rests at an angle with the main pipe. The act of opening the
gas valve simultaneously operates the contact lever through the medium of
the cranked pin and slot the extremities of the lever travelling in circular arcs in
opposite directions, so that on continuing the turning of the valve, the lever
gradually approaches the vertical position whereupon the valve opeus wider and
wider at first only admitting gas through the lighting pipe or byepass and then
through both pipes, at which point the lever is vertical, and finally when the lever
is passing the vertical position the movable electric contact at its upper end bears
against the other insulated stationary contact and completes the electric circuit
causing a spark when breaking said circuit which iguites the gas in the lighting
tube which in turn lights the gas in the main tube. The valve in its travel shuts
off the gas from the lighting tube about the same instant as the spark is produced,

I, ERIK ORLING of 38, Hamngatan, Stockholm, Sweden, Mechanician, do
hereby declare the uature of this invention and in what mauner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to a modification in the construction of gas-lighters of the
auxiliary lighting tube type, its object being to render the same capable of igniting
the lighting flame of Auer-burners by means of electricity.
To this purpose a rod or lever supporting the movable contact is provided with
a slot at its lower end which engages with a cranked pin projecting from an arm
secured to the valve stem, so that the position of the rod or lever is changed by
the turning of the valve stem when opening or closing the gas supply. The
movable contact is attached to the upper end of said rod or lever, the latter being
pivoted at or about its centre to au upright or bracket secured to or forming an
integral part of a ring or washer placed upon the top of the burner tube and
secured in position by the screwing down of the burner cap. A stationary electric
contact is carried at the top of the aforesaid upright near the lighting pipe or
byepass outlet and is suitably insulated. The passage connecting tho interior of
the valve box with the lighting pipe or byepass is arranged and located in the said
valve in such position relatively to the gas conduit pipe that on turning the valve
stem the gas escapes first through the lighting pipe or byepass then through both
the lighting pipe and the main pipe and finally on completely turning the valve,
that is to say when the valve is fully open, gas can only escape into the main pipe
direct from the conduit. The necessity for the lighting pipe or byepass to be
continually alight is thus entirely obvinted.
burner
I will now describe my invention with reference to the accompanying drawings,
Figure 1 of which is a back view and Figure 2 an end view of
provided with my improved lighting devices.
Figures 3, 4 and 5 are sections through the valve box showing the valve,
lighting pipe or byepass, and the gas conduit pipe. Figure 3 illustrates the device
with the valve closed, Figure 4 with the valve partly opened and affording
communication between the gne conduit pipe or main channel and the byepass and
inlet. Figure 5 shows the valve fully opened and allowing the gas a free passage
between the inlet and the main channel but shutting off the byepass.
a Figures 2, 3, 4 & 5 is the gas valve, & Figures 1 and 2 is an arın secured to
the latter. Figures 1 and 2 is a tap projecting from the arm b said tap engaging
with the slot d (Figure 1) in the rod or leverf (Figures 1 and 2) on one end of
which is fastened the movable contact g (Figures 1 and 2).. n is the plate or ring
which is loosely mounted upon the screw threaded part 3 (Figures 3, 4 and 5)
to which the burner cap is screwed in such manuer that the plate or ring is
fastened by the tightening of the cap. From said plate or ring n arises an arm or
upright secured to or forming an integral part of the plate n. The rod or
lever is pivoted at e Figures 1 and 2 to said upright as shewn on the

page_text: constructions illustrated by Figures 1 and 2. The rod or leverf may however be.
rendered movable in its longitudinal direction by forming another slot therein.
To said arm n' is also fastened the stationary isolated contact h. i is the lighting.
pipe, and in Figures 3, 4 and 5 k is the valve-box, the channel to the lighting
pipe and k 2 the main channel.
The operation of my invention is as follows:
When the gas valve a is closed as shewn in Figure 3 the slotted contact lever f
rests at an angle with the main pipe or channel k 2 as shewn in Figure 1. The act
of opening the gas valve simultaneously operates the contact leverf through the
medium of the arm b and tap be and slot d the extremities of the lever travelling
in circular ares in opposite directions so that on continuing the turning of the valve
the lever gradually approaches the vertical position whereupon the valve opens
wider and wider at first only admitting gas through the lighting pipe or byepass i
aud then through both pipes as shewn in Figure 4 the gas heing admitted through!
passing thence through the passago a' in the gas. valve a and upwards through the
passages and 2 in the byepass or lighting pipe i and the main pipe to the
buruer respectively. At this point the lever f is vertical and finally when the lever
is passing this position the movable electric contact g (Figures 1 and 2) at its.
upper end bears against the other insulated stationary contact and completes the
electric circuit, causing a spark when breaking said contact which ignites the gas.
in the lighting tube which in turn lights the gas in the main tube k2. The
valve a in its travel next shuts off the gas from the lighting tube i about the same.
instant as the spark is produced so that when the valve a is fully opened as shewn.
in Figure 5 it only admits the gas through the main pipe 2 to the burner direct
from the source of supply.
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. The improvement of an arm b provided with a tap or projection o and fastened
to the stern of the valve a, said tap or projection c engaging with a slot in
the contact lever carrying a movable contact g substantially as and for the
purposes described, and illustrated in Figures 1 and 2 of the accompanying
drawings.
2. The improvement of so pivoting ate the said contact leverf to an arm or
upright which is part of a plate or ring n mounted on the scrow-threaded
part 3 to which the cap of the burner is screwed, said arm n' and plate or ring n
also supporting the stationary isolated contact in such a way that the whole
device is quickly and easily put on and taken off by respectively loosening and
again screwing up the burner cap all as described and illustrated in Figures 1 and 2:
of the accompanying sheet of drawings.
3. In gas lighters as described in Claim 1, the improvement of providing a.
narrow lighting pipe or byepass i fitted in such a position that the inner mouth of
the channel that connects the interior of the valve box k with the lighting pipe-
or byepass is situated so near the main channel k 2 that the distance between the
interior mouths of the two channels is smaller than the diameter of the openings a
in the valve stem a so that by turning the valve stem the gas escapes first through
the lighting pipe or channel only then through both pipes or channels 1, 2 and
finally through the main channel only whereby the lighting flame is automatically
extinguished when the valve is fully opened substantially as described and
illustrated in Figures 3, 4 and 5 of the accompanying sheet of drawings.
