COMPLETE SPECIFICATION.
Improvements in Self Acting Gas Lighting and Extinguishing
Devices.
I, RICHARD LANDAUER, Banker, of 22, Kleiststrasse, at Berlin, 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 the construction of a device for self-acting opening
and closing of gas-jets at a certain time, making it possible, for example, for a
lantern having been lit by self-action at a certain time in the evening or night to
be extinguished in the same manner in the morning.
In order that my invention may be better understood I will now proceed to
describe the same in relation to the accompanying drawings reference being had
to the letters and figures marked thereon; like letters refer to like parts in the
various figures.
Fig. 1 is a view of a lantern containing the new invention.
Fig. 2 is a front view of the regulating device.
Fig. 3 is a side elevation of the same.
To carry my invention into effect a clock-work is necessary, being arranged
double, according to the works in an alarum-clock and in contact with a double
regulating device making a movement possible at a certain and desired time.
The clock-works are arranged beneath a turner of any accustomed kind, with an
attached lighting device of any possible construction. One of the regulating
devices contained within the clock-works serves as an apparatus to open the
jet, whereas the second regulating device serves to close the jet and in this way
naturally immediately extinguishes the light.
gas-
Both regulating devices are in connection with a toothed half wheel in such a
manner once checking its rotation received in consequence of a suitable spring
and then again setting the same at work. The toothed half wheel mentioned
gears with a sector being rigidly connected with the pivot of the gas-jet. In
the drawings a, represents a gas-pipe, b, the clock-works, c the regulating device
for the time of lighting and d, for extinguishing the light, e, the works for
actuating the toothed half-wheel f. g, is the sector and h cock of the gas-
jet, whereas 2, represents a self-acting gas lighter any construction, k the checking
device for lighting and m the checking device for extinguishing the gas light.
In ordinary practice the time-gas-jet opener and closer has the following way
of action.
The regulating hand c, which determines the time of lighting, is turned on the
certain hour at which time the gas is desired to burn, for instance 6 o'clock being
equal to the 18th hour of day; and the extinguishing hand d is put on the hour
at which it is desired to extinguish the light. As soon as the hour for lighting
has been reached the checking device k, will be discharged in any desired and
known manner and the toothed half-wheel f is rotated, at the same time rotating
the sector g, compelling the gas-cock to turn in such a manner so as to permit the
gas to stream out.

page_text: Sector 9 remains in this position until the extinguishing of the light is desired,
say at 4 o'clock in the morning. As soon as the hand, reaches this hour, the
checking device m is released, giving the possibility for the toothed half wheel f
to rotate again, still this time making a backward motion, by means of a spring,
counter-weight or similar device.
The sector is again taken along compelling the gas-jet to close and the flame to
extinguish. The clock works arrangement can as already said be of any customary
suitable construction.
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:
-
1) In a self-acting gas-lighting and extinguishing device the arrangement of
clock-works in connection with a gearing for the purpose of opening and closing
a gas-jet at a certain time as described and illustrated in the accompanying draw-
ings.
2) In a self-acting gas lighting and extinguishing apparatus the arrangement
of clock-works in connection with a gearing put to action by a suitable spring
after discharge of a checking device for the purpose of opening and closing a gas
jet at a certain time as described and illustrated in the accompanying drawings.
In a self-acting gas lighting and extinguishing device the arrangement of
clock-works in connection, with a toothed half wheel gearing with a sector attached
to the pivot of a gas-cock, both being put to action by a suitable spring after
discharge of a checking device for the purpose of opening and closing a gas-jet
at a certain time as described and illustrated in the accompanying drawings.
Dated this 28th day of December 1897.
