HELIODOR ROSTIN AND STANISLAUS SZUBERT, OF BERLIN, GERMANY.
GAS-BURNER.
SPECIFICATION forming part of Letters Patent No. 681,980, dated September 3, 1901.
Application filed March 22, 1901. Serial No. 52,355. (No model.)
To all whont it may concern:
Be it known that we, HELIODOR ROSTIN, residing at No. 144. Uhlandstrasse, Wilmersdorf, Berlin, and STANISLAUS SZUBERT, residing at No. 40 Kleiststrasse, Berlin, Prussia, Germany, subjects of the King of Prussia, German Emperor, have invented certain new and useful Improvements in Gas-Burners, (for which we have made application for Letters Patent in Germany August 3, 1900, R. 14,531, and December 24, 1900, $14,387,) of which the following is a specification.
Our invention relates to improvements in gas-burners; and the object of our invention is to provide means for cutting off the supply of gas to the burner or the escape of gas from the burner when the flame has accidentally been extinguished and the gas cock or valve is open, thereby preventing the danger of gas explosions and suffocation caused by the escape of gas.
Our invention particularly has for its purpose to improve devices of this kind already existing, by which the heat developed by the burning flame is utilized to perform the eX- pansion of atmospheric air, gas, or a volatile fluid, which by the increase of its volume within a closed chamber works a pressure on a membrane and forces the same to the outside, by which motion means are actuated to keep the Valve of the burner open as long asthe flame burns. It the flame happens to be extinguished, the air, gas, or fluid expanded by the heat will cool down and the pressure which had kept the valve open will relax, thus permitting the valve to be automatically closed by a spring or other means.
Theimprovements of ourinvention are particularly destined to be employed in connection with burners for incandescent gas-light, but the use of several particular features of our invention is not limited to burners of the said kind.
The improvements of our invention are illustrated by the accompanying drawings, in which- Figure l is a central vertical section through an incandescent gas-burner fitted with the improvements of our invention. The gas-valve is closed. Fig. 2 is a central vertical section through the same burner seen from the other The gas-valve is opened before the side.
lar and bracket, serving to secure the device for actuating the gas-valve. Fig 8 is a sectional view of the key for opening the gas valve, and Fig. 9 is a sectional view of the same key seen at right angles to Fig. 8.
The same letters indicate the same parts throughout all'figures.
Referring to Figs. 1 and 2, a is an incandescent gas-burner of the kind generally in use. The improvements of our invention are easily to be fitted to such burners and to burners of any other construction without necessitatin g any material work for adapting the device for opening and closing the gas-valve. To the shoulder of the burner-tube b a collar 0 is loosely mounted, having a bracket or eX- tension-piece d, as shown in Figs. 6 and 7, the bent lugs e of which are made to form bearings for the key f for opening the valve g, as hereinafter more fully described. The end of the bracket d is slotted to receive the tube h, which is secured to the bracket 01 by a nut t or any other convenient means. The upper end of said tube h opens into a box or chamber of metal, carrying a metal rod on, which extends upward in close proximity to the flame outside of the incandescent mantle. The lower end of said tube 72, opens into a hollow body at, the lower side of which is formed by an elastic metal disk, preferably corrugated in the manner of the yielding sides of an aneroid barometer. The outside of this metal disk 0 carries a small stud 19. To the bracket 61 or to the upper rigid side of the body 1) a springy wire q is secured, the free end of which extends through an aperture of the burner-tube Z7 and holds the rod 1", by which the valve g is suspended. The said valve may be formed with a cone fitting into a corresponding seat or it may be shaped globular or otherwise. The key f carries a toe t, and when the said key f has been introduced into the bearings of the lugs e from the right to the left of Figs. 8 and 9 the tube .9 of the key-handle u is put onto the square end of the key f.
The function of the device described is as follows: Before lighting the gas of the burner all parts take the position as shown in Fig. 1. The gas-cock is opened, as usual, or a valve admitting gas may be opened by electrical or other means. The gas, notwithstanding, cannot enter the burner before the handle 11. of the key f is turned into the horizontal position indicated by dotted lines in Fig. 2. By turning the key and handle, as described, the toe t of said key' will bear against the springy wire'q and force the same down as much as to open the valve 9 sufficiently for admitting gas into the burner and to the flame to be ignited. At this time all parts take the position indicated in Fig. 2. When the flame is burning, its heat will quickly increase the temperature of the small metal rod 171, placed in proximity to the flame, and said rod will conduct the heat to the metal box or body 70, the gaseous or volatile contents of which will increase in volume, and, entering the body n through the tube h, will force the metal disk 0 down as much as to bring the stud 19 into contact with the springy wire (1 and to press the same farther down, thereby increasing the width of passage of gas through the valve-seat. The springy wire q being forced downward from its position shown in Fig. 2 will leave free the toe 15 of the key f, and the latter will be free to return into its original position,(shown in Fig. 1,) owing to the proper weight of the key-handle a. At this time the parts will take the position indicated in Fig. 3, and they will continue to keep this position as long as the flame continues to emit heatt'. e., as long as it is burning. Suppose now that the flame be accidentally extinguished and the gas cock of the burner left open. The gas will for a very short time continue to escape through the burner, but as soon as the box or chamber it will cool down its contents will again contract and the pressure operated upon the elastic disk 0 will be released, the said disk 0 and stud 19 will return into the position shown in Figs. 1 and 2, and the valve 9 will be lifted and pressed against its seat by the springy wire q. The said valve being closed, no further escape of gas will go on, though the gas-cock continues to be open.
Though the construction, as shown and before described, of suspending the valve g to a spring-y wire (1 under influence of the elastic metal disk 0 and of arranging the valverod 1' in a manner to pass through the top plate of the injector and have a sliding motion within the same has been found to give good results, yet a variety of other mechanical means could be employed for transmitting motion from the disk 0 to the valve for opening the same and for automatically clos= ing the same after the flame has been extinguished.
To prevent the box or chamber from being spoiled by the heat of the flame, we prefer to locate said box or chamber outside of the burner-top and to conduct the heat from the flame to said chamber It by means of a metal rod m. Otherwise the device would soon be destroyed by the direct heat in a degree to come out of working order.
The motion obtained by the pressure of the gaseous or fluid. contents of the chamber It, acting upon the elastic metal disk 0, may further be utilized to perform other mechanical or electrical effects-such, for instance, of closing or interrupting an electrical circuit, which,by the aid of electromagnets or the like, will be able to sound bells or give other signals or to operate means for closing the main supply-valve of the gas-conduit.
To claim as our invention 1. The combination, with a gas-burner, and a hollow body provided with an elastic portion having one side directly exposed to the external air, of a gas-valve arranged to be actuated by the movement of the elastic portion and controlling the supply of gas to the burner, a hollow chamber located adjacent to the burner and in communication with the hollow body, and a rod of heat-conducting material carried by the said hollow chamber and extending into close proximity to the burner-flame.
2. The combination, with a gas-burner, and a hollow body provided with an elastic portion having one side directly exposed to the external air, of a gas-valve arranged to be actuated by the movement of the said elastic portion and controlling the supply of gas to the burner, a hollow chamber, said chamber arranged to be heated by the burner, a connection between said hollow chamber and the hollow body, and mechanism for opening the valve prior to the operation of the elastic portion of the hollow body.
3. The combination, with a gas-burner, and a hollow body provided with an elastic portion, of a hollow chamber in communication with said hollow body and arranged to be heated by the burner, a collar and bracket device connected to the burner and arranged to support said hollow body, said bracket having bearings, a key turning in the bearings, a spring under the control of both the elastic portion of the hollow body and the key, and a valve arranged to control the supply of gas to the burner and connected to the said spring.
In witness whereof we have hereunto set our hands in presence of two witnesses.
