Improvements in Means for Controlling Distant Gas Burners.
I, WILHELM POST, of Iserlohn, in the Empire of Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The following invention relates to improved means for controlling distant gas
burners; the improvement consists in an arrangement for providing a constantly
burning pilot flame, in an improvement of the gas cock opener and the construction of
the gas cock.
In order to have a constantly burning pilot flame the use of a special pipe deviating
from the principal gas pipe as hitherto used is avoided by making round the inner
movable plug of the cock body a groove in communication with a longitudinal bore
in the cock body in order to allow a continual passage to a small pipe screwed on the
top to feed the pilot flame. In order to adjust this flame or to stop it entirely a
regulator can be arranged in the form of a screw pin or otherwise. The plug is
conical and for the passage of gas to the principal flame it is not as hitherto provided
with one line of holes only arranged annularly but with two lines, thus with the small
diameter of the plug and consequently small friction the holes may be sufficiently
small to be closed tightly in a suitable manner in the cock body while they are
collectively big enough to let pass when open a sufficient quantity of gas. Suitable
to these two lines of holes the cock body has also two longitudinal bores.
For intermittent movement of the cock a horizontal electro magnet is arranged
with strong bevelled poles before which is a prismatic and flat armature hinged at the
lower end. In order to make the latter by its own weight drop back into its resting
position a small weight is arranged therein. This weight replaces the springs
ordinarily used and allows of equal adjustment of all the apparatus connected in the
circuit.
On the armature a two armed anchor or dog has been arranged to operate a ratchet
wheel on the gas cock thus on each passage of the electric current the one arın moves
the ratchet wheel for one tooth whilst the other arm prevents the ratchet wheel
turning too far as it might do if the current were strong. On the other end the cock
carries also a toothed wheel into which a pawl engages for preventing backward
movement.
The turning of the cock must be effected so that on one passage of the current, one
bore of the plug comes into communication with the gas channels in the cock body,
and this communication is interrupted by the next following passage of the current
in order that by one closing of the circuit the lighting by the next the extinguishing
of the chief flame is effected. The number of teeth of the toothed wheel must
therefore be double that of the gas passage openings in each line of borings in
the plug.

I, WILHELM POST, of Iserlohn, Germany, Manufacturer, 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:-
The following invention relates to improved means for controlling distant gas
burners; the improvement consists in an arrangement for providing a constantly
burning pilot flame, in an improvement of the gas cock opener, and the construction
of the gas cock itself.
The annexed drawing shows in the Figs. 1 and 2 two vertical sections; in Fig. 1
the armature being omitted; Fig. 3 is a horizontal section below the upper cover
and Fig. 4 shows a section on a larger scale through the cock. Figs. 5, 6, and 7.
represent a modification of the arrangement of the gas transit borings in the
cock.
In order to have a constantly burning pilot flame on distant gas burners with gas
cock moved by an electro-magnet, the use of a special pipe branching from the
principal gas pipe, as hitherto used, is avoided by making round the inner movable
plug of the cock body, a groove c in communication with a longitudinal bore d in
the cock body a in order to allow in any position of the cock a continual passage of
gas to a small pipe e screwed on the top to feed the pilot flame. For adjusting or
extinguishing the pilot flame a screw acting as a cock can be arranged.
The plug b is conical in order to obtain a better tightening of the same and for
the passage of gas to the principal flame it is not as hitherto provided with only one
line of holes arranged annularly, but with two lines and i; thus with the small
diameter of the plug and consequently small friction the holes may be sufficiently
small to be closed tightly in a suitable manner in the cock body while they are
collectively big enough when open to let a sufficient quantity of gas pass. Coinciding
with these two lines of holes the cock body has also two longitudinal bores k and l.
For intermittent movement of the cock a horizontal electro-magnet m is arranged
with large bevelled pole plates n before which a prismatic and flat armature o is
hinged at the lower end. In order to make the latter by its own weight drop back
.into its resting position when the current circuit is opened, a small weight p is
arranged thereon. This weight replaces the spring ordinarily used and allows of
equal adjustment of all the apparatus connected in the circuit.
On the armature a two armed anchor or dog has been arranged to operate a
ratchet wheels on the gas cock; thus on each passage of the electric current the one
arm 7 moves the ratchet wheel for one tooth, whilst the other arm 71 prevents the ratchet
wheel turning too far as it might do under the impulse given by the action of a
strong current. On the other end the cock carries also a tooth wheel t into which a
pawl u, pivoted on the body a engages for preventing backward movement.
The turning of the cock must be effected so that on one passage of the current,
one bore of the plug comes into communication with the gas channels k or in the
cock body and this communication is interrupted by the next following passage of
the current in order that by one closing of the circuit the lighting and by the next
the extinguishing of the chief flame is effected. The number of teeth of the toothed
wheels must therefore be double that of the gas passage openings in each line of
borings in the plug.
As shown in Fig. 4 the ratchet wheels has 12 teeth so that the plug on each of the
two respective spots must have 3 borings h, i consequently 6 openings. It is easily
understood that when according to the position of the cock in Fig. 4 the armature is
attracted by closing of the circuit current the plug is turned for the distance of one
tooth closing the channels and so that the chief flame expires. By the next

page_text: attraction of the armature the following bore h (or i) enters into communication with
the channel (or ) and the chief flame is lighted again and so on.
As mentioned already with all these movements of the cock the communication of
the pilot flame tube with the gas pipe is never interrupted in consequence of the
groove round the movable part of the cock so that the pilot flame remains continually
burning.
t
If in the described construction of the gas cock the borings for the gas passage
to the chief flame are arranged according to the modification shown in Figs. 5-7, one
is enabled to put into action a number of gas cocks connected with the same circuit
so that the lighting and extinguishing of the flame is effected by groups.
In the
construction shown in Figs. 1-4 the plug contains half as many borings as the ratchet
wheel has teeth, so that the apparatus opens and closes alternately the passage of
the gas to the burner, all the apparatus of one and the same circuit being opened at
once by a circuit and being closed at once by the next one or vice versa.
If these apparatus are arranged on a number of street lamps the use of only
one circuit would then either light all the lamps at once or extinguish them all at
once.
In street lighting all the lamps are sometimes lighted at once, but they are often
extinguished in groups, the plug of each group are for this purpose provided with
special borings allowing the lighting of all the lamps at once but afterwards
extinguishing them in groups one after the other, keeping the ring-groove in the plug
for continual feeding of the pilot flame.
In putting two groups of lamps into the same circuit the plugs 6 of the one group
(Fig. 7) have only for each third tooth of the ratchet wheels a boring / so that only
at each third closing of circuit the gas passage to the burner is opened.
On the second group (Figs. 5 and 6) instead of the simple borings, but otherwise
situated analogous to the borings h in Fig. 7, borings of 2 shapes are arranged as the
real borings are extended in the form of grooves von the circumference of the plug
so far that they at each second circuit-closure still communicate with the gas passage
channel in the plug.
If now all the plugs of both groups of lamps are adjusted so that the main supply
of gas can pass through the apparatus and be lighted on the pilot flame (Figs. 6
and 7 ) then by the following current closing the plugs are moved on for a distance
of one tooth of the ratchet wheel 8 and the parts marked 2 come under the passage
channel. This on the first group is a closed field extinguishing therefore the lamps of
this group; on the second group it is one of the grooves v the lamps of this group
remaining therefore lighted. By the next circuit closing in both groups the closed
fields enter at 3 under the passage channel so that the lamps of both groups are then
extinguished. By the following circuit closing the borings of both groups of plugs
enter at 4 under the passage channel so that then all the lamps of both groups are
lighted and so on.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
Improvements in means for controlling distant gas burners, comprising:—
1. A cock having a conical plug and round which is a ring groove c, for uninter-
rupted gas passage to a pilot flame in combination with two or more annular groups cf
small gas outlet borings in the conical plug for the passage of gas to the chief flame
in order to obtain a red ution in the diameter of the plug and a better tightening of
the borings.
2. A loaded electro-magnet armature o arranged before bevelled pole plates for
the purpose of enabling it to fall back of its own weight when the circuit is
opened.
3. The arrangement whereby the plugs of two groups of lamps are moved
symmetrically by each current-closing, but open or close the gas outlet openings

page_text: of the cock unsymmetrically, comprising annularly prolonged borings in the plugs
of one of the two groups whilst the plugs of the other group have analogously situated
non-prolonged borings.
