COMPLETE SPECIFICATION.
An Improved Device for Automatically Igniting and Extinguishing
Lamps or Raising and Lowering the Flames of Gas Burners.
We, JULIUS SCHREINER, of No. 49 Annen Strasse, Berlin, Germany, Mechanic,
and BERNHARD SALZ, of No. 14 Wasser Gasse, Berlin, Germany, Merchant, do
hereby declare the nature of our said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to an improved device for automatically igniting and
extinguishing lamps, raising and lowering gas flames, and the like, and is especially
adapted for employment in rooms, cellars and other localities which are temporarily
used, the said device being operated in opening and closing the door.
We will first describe our improved device applied to a lamp for burning light
hydro carbons and the like. The movement caused by opening and closing a door
is, by means of a rod attached to the said door, transmitted to a mechanism of the
lamp in order to ignite and extinguish the same. In the accompaning drawings,
Figure 1 represents a benzine lamp with igniting and extinguishing devices, partly
in elevation and partly in section.
Figure 2 is a vertical section of the lamp on the line -y in Figure 3.
Figure 3 is a horizontal section on the line - in Figure 1.
Figure 4 is an end view partly in section.
Figure 5 is a detailed representation of the rod for operating the extinguishing
device.
The lamp a' is so surrounded by a casing a that an opening of sufficient size is left
in the front wall, so that the lamp can be readily removed for filling. The casing
also contains the mechanism for operating the igniting and extinguishing device, and
also the rod b, which is limited by the studs, in its reciprocating movement caused
by the opening and closing of the door.
The rod is loosely connected to a rack c, Fig. 4, which is in gear with two
ratchet wheels d, e, which can turn only in one direction and of which the wheel d
operates the extinguishing device, the wheel e the igniting device.
The mechanisms of the lamp are, according to the drawings, so constructed that
when the rod b is advanced in closing the door after entering the room or other
locality and leaving the same the lamp will be ignited or extinguished, whilst the
mechanism is not operated in opening the door. Through the movement of the rack c
the ratchet wheel à receives one fourth of a revolution which is transmitted to two
pins, pegs or studs d, attached to the wheel d, which gear into a recess in the
rod by means of the pin d. A ring g' connected by means of an arm to the end
of the rod which glides up and down on the wick sheath
of the lamp a and is
drawn so far down by the sinking of the rod that the wick sheath with the wick
will be given free. A cap h which had hitherto rested on the ring gl is raised by the
rod by means of the arin h', which turns on the pivot h² and is held in the recess f
of the rod When the wick sheathy has been given entirely free, the rack c will,
by the further movement of the rod b, communicate a quarter revolution to the
ratchet wheel e, which is transmitted to an axle 1, to which a
connected.
tapped wheel k is
This tappet wheel presses in turning a percussion hammer m to one side and gives
the same suddenly free, so that the same under the action of the spring n will be
impelled forwards against the anvil o and ignite an amorce pill, so that the flame
thus produced will be led through the piece of tube o' and the wick of the lamp
ignited.

page_text: The amorce pills are arranged on a strip or band which is automatically trans-
ported by the transport wheel 7. In leaving the room the rod and rack c will be moved
back and in closing the door, be again advanced.
In consequence of the partial revolution of the ratchet wheel d caused by the fore-
going the pin d leaves the recess f¹ of the rod f, releases the same, which, in
consequence of the pressure of the spring is driven upwards, raises the ring g
and presses the cap onto the ring g', thus extinguishing the flame and closing the
wick tube.
Figures 6 to 11 represent the application of our improvements to igniting and
extinguishing gas flamies in opening and closing the door to rooms or apartments.
The burners are either provided with small igniting flames or the flame turned down
so low that only a very small flame remains barning. The arrangement is such that
the flame is turned full on or reduced to a small Hame at every alternate opening
of the door.
Figure 6 is a part longitudinal section and part side view of the device with the
door closed and almost entirely closed cock leaving the flame burning very small.
Figure 7 is a side view of the device with opened door and opened cock, the flamo
burning with full power.
Figure 8 is a section of the device on the line A-B in Figure 6.
Figure 9 is a section on the line C-D in Figure 6 seen from above.
Figures 10 and 11 are details of the invention in two sections at right angles to
each other.
A is the door, to which the guide arm a with slot is attached. The one end c
of a helical spring d on the bolt e gears into the slot 6 of the guido arm a. The
bolt e with its square ends is securely held between two angle irons ƒ and g and the
upper end of the spring d is connected to the bolt e that the end c of the spring can
be turned several degrees but will always return to its original position as soon as the
tension on the spring is released.
A pawl casing carrying a pawl i which is continuously pressed upwards by a
spring k against a suitable stop, is fixed to the free end of the spring d. When the
door A is opened the pawl comes into gear with a ratchet or tappet wheel !
arranged to turn, in a casing B and provided with two pins or studs m m arranged
diametrically opposite to each other. When the cock is almost entirely closed so that
only a very small flame remains burning, Figure 6, a T-piece n rests on the same,
said T-piece being provided with a slot o
The T-piece can move in a vertical direction and carries in the slot o a helical
spring p which abutts at its lower end against a lateral extension
of the T-piece n
whilst the upper end presses against a cross piece of the casing B. The upper end
of the T-piece n is jointed to a rod s, the other end of which is jointed to a fork t
which embraces the lever u fixed to the cone or plug of the cock. The fork t can be
readily slid onto the lover u and securely held but readily released by means of an
eccentric attached to a small lever, Figures 10 and 11, which turns on a bolt in the
fork t.
we is the gas cock, a the gas burner. The cock is carried preferably by an army of
the angle iron f, and is in appropriate connection with the main pipe. The operation
of the device is as follows:-
In opening the door in the direction of the arrow, Figure 6, the pawl i is moved in
like direction and turns thereby the wheel a distance equal to 90°. As is evident
from Figure 7, the action of the pawl on the ratchet or tappet wheel / ceases as soon
as the same has been turned 90°. Through this movement of the wheel one of the
pins or studs m and simultaneously the T-piece n are raised into the position shown
in Figure 7 and the spring put under compression. In moving the T-piece upwards
the plug of the cock is moved into the open position, the gas turned on and the full
flame produced, Figure 7.
If the door is now closed the pawl i glides back under the wheel into its original.
position, Fig. 6. The flame burns so long bright, Figure 7, until the door is

page_text: again opened when the ratchet wheel will be given a quarter turn and the pin m
moved downwards. As soon as the pin or stud m is moved down the spring p presses
the T-piece down, thus causing a turning of the plug of the cock into the position
shown in Fig. 6, so that the flame burns only with a very small flame.
The object of the readily releasable connection between the lever u with the fork t
is to be able to put the device out of operation which is effected by turning the
eccentric v in the fork to the left, so that the connection is released and the fork can
be readily drawn from the lover u.
It will be evident from the foregoing that the parts of our improved device
can be modified in various ways without departing from the tenor of our said
invention.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1:—The improved device for automatically igniting and extinguishing lamps in
rooms or apartinents not in permanent use when the door is opened and closed,
characterised by the arrangement whereby the movement of the door is transmitted to
a toothed rod or rack c loosely connected to the rod b, said rack c moving the ratchet
wheels d, c, of the igniting and extinguishing device only in one direction so as to
lower the ring g' to the wick tube and raise the extinguishing cap attached to the
lever by means of the rod f, the percussion priming being operated by the tappet
wheel k, the return movement being automatically effected by the spring 9, sub-
stantially in the manner set forth and shown.
2: The improved device, according to which in opening a door an otherwise very
small burning flame is caused to burn with a bright flame but will be again reduced
to a small flame when the door is again opened, characterised by the guide piece
gearing over the bent end of a vertically arranged helical spring and attached to the
door, a pawl attached to the arm of the spring by means of which a ratchet wheel is
turned in opening the door and the T-piece operated, the said movement being so
transmitted by a jointed rod to the plug of the cock that by moving the T-piece in
one direction the cock is opened whilst a movement in the other direction will cause
the cock to be almost entirely closed, substantially as set forth and shown.
3-The general construction, and combination of the respective parts, together
forming our improved device, substantially as set forth in the foregoing specification,
and illustrated in the accompanying drawings.
