A BURNER ATTACHMENT FOR SHUTTING OFF THE GAS SUPPLY AS THE FLAME IS BLOWN OUT
Year: 1884

page_text: COMPLETE SPECIFICATION.
I, CHARLES PIETZ, of 82 Nassau Street, in the City and State of New York.
United States, Gentleman, do hereby declare the nature of my invention for
A BURNER ATTACHMENT FOR SHUTTING OFF THE GAS SUPPLY AS THE FLAME IS
BLOWN OUT, 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 gas burner which is provided with an attachment by
means of which the flow of gas will be cut off, if the flame is blown out. It has
frequently happened that gas has been blown out by inexperienced persons, who
have been suffocated by the subsequent continued flow of gas. To avoid such
accidents is the object of my invention, which consists principally in the combination
of a gas burner with a surrounding fan blower, which is revolved if the flame is
blown out and which thereby shuts off the supply of gas.
The invention also consists in the details of construction hereinafter more fully
pointed out.
In the accompanying drawing Fig. 1 is a perspective view of a gas burner,
provided with my improvement, showing it when the gas partially turned off.
Fig. 2 is a longitudinal central section of the same, with the gas turned on.
Fig. 3 is a cross section on the line x, x, Fig. 2.
The letter A represents a gas burner of the customary or suitable construction.
Around the upper portion thereof, 1 place a fan blower a seated upon a sleeve b,
that surrounds the upper part of the burner. The upper edge of the sleeve b is
scalloped as shown, to decrease the contact surface. The fan blower has upright or
inclined blades, and is revolved by the air current, if the gas is blown out.
Through the side of burner A, extends a rod d to the inner end of which is
attached a valve in manner hereinafter specified, while the outer end carries a key
or arm e. This key is weighted at its upper edge, by a weight fand is of such a
length, that when in an upright position, as shown in Fig. 2, it extends with its
top between two of the blades of the fan blower a.
The rod d passes through a sleeve 9 and is connected to a valve rod h that
carries the ball valve i. The connection between rods d, h, is made by means of a
staple and eye as shown, so that when the rod d is partially revolved, the valve

page_text: rod h, and with it the ball valve i will move up or down vertically. j is a valve
seat formed within burner A. This valve seat is provided with a slit (seen in
Fig. 3), which is closed when the ball valve is raised.
The operation of the device is as follows:-
In its normal condition, the weighted key e projects between, and is held in an
upright position by the blades of the fan blower, and the valve is open, permitting
the free passage of gas (Fig. 2). As soon as the gas is blown out, the fan blower a,
is revolved and the blades striking the key e, will throw it down (Fig. 1). As
soon as the top of the key is free of the fan blower, its weight f, will cause the key
and with it the rod d to revolve further, until the valve i, is raised up to its seat j.
The valve will now be closed and the further admission of gas cut off. In this way
an automatic extinguisher is provided.
It is evident that in addition to my attachment the ordinary gas cock is used.
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. The combination of burner A, with fan blower a, and with key e, extending
between the blades of the fan blower, and connected with a valve within the
burner substantially as herein shown and described.
2. The combination of burner A, with fan blower a, rod d operating a valve
within the burner, and with key e, having weight f, substantially as specified.
3. The combination of burner A with fan blower a, sleeve b, rod d and with the
key e connected by rod d with a valve within the burner, substantially as and for
the purpose specified.
4. The combination of burner A with fan blower a, rod d, weighted key e,
sleeve g, and with the valve rod h, valve i and seat j, substantially as specified.
Dated this 12th day of August 1884.
