Improvements in and relating to the Burners of Gas Lamps.
I, RUDOLF REINHARD, of 23, Hühnerposten, Hamburg, Manufacturer of Metal
Goods, 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 relates to a device applicable to street gas lamps having double
burners the jets of which are ignited by means of separate igniting jets. The
object of this device is to enable the said igniting jets to be extinguished whilst
the main jets are burning.
The improved device differs from other known devices serving a similar purpose
by the fact that the supply of gas corresponding to the various phases of the
burning of the jets, can be regulated in an extremely accurate manner without
the mechanism necessitating any specially careful manipulation in adjusting it
for the various phases, and without the cleaning out of the passages etc. (which
The con-
is necessary from time to time) offering any difficulties whatever.
struction of the mechanism is also, in contradistinction to that of the known
regulating devices, extremely simple, so that it can be carried out by any ordinary
expert, whilst when in use there cannot take place any wear which might inter-
fere with the proper operation of the mechanism, and the several parts must
always retain their relative positions when once such have been set and adjusted,
which is not the case with the known devices.
This invention is illustrated in the annexed drawings:-
Figure 1 shows in central sectional elevation a double burner street lamp pro-
vided with this device.
Figure 2 is a side elevation of Figure 1, in section on the line u, u, Figure 1.
Figure 3 is a front elevation of the body containing the regulating slide valve.
in front end view, the lid being removed.
Figure 4 is a rear elevation of the same, likewise with the lid removed.
Figures 5 to 8 show the various positions of the rotary valve.
Figures 9, 10 and 11 are cross sections through the burner-carrier on the
line x, y, and z of l'igure 1.
According to this invention the essential part of the apparatus as illustrated,
consists in the slide valve body A which contains the rotary slide valve B. The
body A is divided by a vertical wall a on the front side of which (Figure 3)
there are arranged chambers I, II, III, IV, which communicate at the top by
means of holes 2, 3, with the pipes 3, 3, that convey the gas to the main jets,
and by means of holes i, it, with the pipes o¹, o, that convey the gas to the
igniting jets. Each of the chambers is connected by means of a hole (chamber I
is connected by two holes) with the space m behind the wall a into which the
gas enters in the direction of the arrow (Figure 2) and in which the slide B
is situated and bears firmly against the wall a. The pin of the slide is led
forwards through the lid al of the chambers I to IV and there it is provided with
a handle 62. Upon the back of the slide B there acts a spring that is held

page_text: by means of a cover m¹ which closes in the space m and in which there is also
situated a cleaning screw m². The slide is formed with a gap s, and according
as this
which is moved in front of the holes which are formed in the wall a, and
the gas to the chambers I to IV, the gas passes into the pipes o¹, o²,
03, 4, and to the jets.
In the position shown in Figure 4 the gas passes out of the chambers I to IV
to the right and to the left hand through i, o, and, to the two igniting jets.
The main jets are extinguished. In the position shown in (Figure 5) gas stiil
passes to the right hand through 4, o, to the igniting jet, and now also to the
main jet on the left through, o, the igniting jet on the left is extinguished.
If the slide is further rotated out of the position (Figure 5) then in the position
Figure 6 the passage 2, 02, to the main jet on the right is opened, but the pass-
age, o, from chamber IV to the igniting jet on the right is also still open so
that the main jet can get ignited thereby and then only after the slide has been
rotated into the position Figure 7, the igniting jet on the right is extinguished,
and now both main jets are burning.
In the position Figure 8, the main jet on the right which is fed through the
passage, 02, is burning whilst the passage, o, to the main jet on the left
has been shut, after the passage i, o, to the igniting flame has been opened, and
the latter has been ignited by its own main jet.
By reason of the arrangement of the rotary slide it is rendered possible to
arrange the several passages (the holes which open from the gas space m through
the wall into the chambers I to IV) at relatively great distances from one
another, so that in adjusting the slide handle by hand, large differences can
occur at times without such differences interfering with the desired supply of
gas to the jets; the passages will even then be always connected up together
in the desired way, even though there be a certain amount of play in the setting
or adjustment of the handle.
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―
A rotary slide valve for the double burners of gas lamps, which is formed with
a gaps and which is rotated along a wall of a chamber m having a gas supply,
said wall being formed with apertures and with chambers I, II, III, IV, the
arrangement being such that the slide valve gaps which bridges over at least
two of the chamber inlet apertures, connects the chambers one after the other
in such a manner with the gas supply space m that the main jets and igniting
jets which communicate with the chambers (I to IV) through passages (i to ¹)
and pipes (o to o*,) can obtain a supply of gas.
