JOSEPH THIERS, OF NORFOLK, VIRGINIA.
SELF-CLOSING OR SAFETY GAS-BURNER.
' Specification of Letters Patent.
Application filed January 26.1905. Serial No. 242.768.
Patented Aug. 29, 1905.
To all whom it may concern:
Be it known that I, JOSEPH THIERS, a subject of the Emperor of Austria-Hungary, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented new and useful Improvements in Self-Closing or Safety Gas-Burners, of which the following is a specification.
This invention relates to self-closing or safety gas-burners; and the principal object of the invention is to provide a gas-burner which will automatically cut off the flow of gas through it at all times when the gas is not ignited at the tip or outlet end of the burner.
It often occurs that the gas-cock to an ordinary bracket or fixture is accidentally turned on after the gas has been extinguished, and the gas is thus allowed to escape. Many of the gas-cocks in use are not provided with a suitable stop to prevent the key from being turned too far, and in using such a cock the gas is liable to be extinguished and then turned to the open position, the gas then escaping without being consumed. Then,again, persons unaccustomed to the use of gas are very liable to blow out the flame, and thus permit the unconsumed gas to escape. Under such conditions or under any circumstances in which unconsumed gas is permitted to flow through the burner my invention is designed to immediately cut off the flow automatically.
The objects and advantages above referred to are attained by means of the construction illustrated in the accompanying drawings, in
' which Figure 1 is a view in side elevation and partial section of a gas-burner of the mantle type and having my invention applied thereto. Fig. 2 is a central vertical section of the same. Fig. 3 is a perspective view of the thermostatic ring and the depending trigger which holds the valve-lever in a position to unseat the valve when the gas is burning. Fig. 4 is a detail view of the valve, its stem, and the bent lever which supports the same. Fig. 5 is a detail view illustrating the gravity-detent which holds the valve-lever in position to open the valve when the gas is first ignited, the trigger for releasing the detent, and the valve-lever and valve. Fig. 6 is a detail perspective view of the valve-seat.
Referring to the drawings for a more de' talled description of my invention, the numeral 1 designates the burner-tube of a mantle gas-burner, 2 is the chimney-support, and 3 is the mantle, said parts being of the usual or any suitable construction aside from the attachment thereto of my improvements.
At the lower end of the burner is a fitting or plug 4. having an inlet-opening 5 and provided with a threaded boss 6 at its upper end, which fits within a valve-section 7. Near the upper end of the section 7 is a concave valveseat 8, provided with a series of openings or perforations 9 and a central aperture 10, through which the valve-stem passes and in which it is free to move. Journaled in the opposite side Walls of the enlarged upper end 11 of the burner-tube is a lever 12. formed of wire of suitable gage and having a depending bent arm 13. Connected centrally to the lever 12 within the burner-tube is a hook 1 1, and suspended from this hook is a valve-stem 15, provided at its upper end with a sh"ort section of chain 16 or other suitable flexible connection to be engaged by the hook 14.. The valvestem 15 is guided in its vertical movements by means of a centrally-disposed guide-loop 17, secured within the burner and through which said stem passes. At the lower end of the valve-stem 15 a weighted valve-head 18 is connected by means of a flexible link 19 or other similar device. At the upper end of the burner-tube a ring 20 is removably fitted, said ring having a wire-gauze or foraminous top or crown 21 of usual form.
A thermostatic strip 22 of suitable metal is secured at one of its ends to the ring 20 and surrounds said ring at its upper end in proximity to the foraminous top or crown 21. The thermostatic strip 22 is unattachedto the ring 20 except at one of its ends, the oppo site end of said strip having secured thereto a depending trigger 23, the lower end 24: of which is bent at right angles for a purpose which will presently appear. A gravity-detent comprising a rod or wire 25, a weighted knob 26 at its lower end and a disk 27 at its upper end, is mounted to slide freely in brackets 28, extended inward from the chimneysupport 2. The outer edge or periphery of the disk 27 is beveled off to engage one of a series of notches 12*, formed in one side of the lever 12.
The operation of my invention may be described as follows: When it is desired to ignite the gas, the gravity-detent is pushed up by means of the knob 26, the disk 27 engaglever in a position to unseat the valve-head 18 from the valve-seat 8 to permit the gas to flow through the burner-tube and be consumed. The heat from the ignited gas immediately expands the thermostatic strip 22,
which moves the trigger 23 into contact with the arm 13 of the lever 12, and thus releases the disk 27 from the notch 12 and permits the detent to drop or slide in its bearings to its lowermost position. While the gas is burning the trigger 23 will hold the depending arm 13 in a position to insure the unseating of the valve-head 18 from the valve-seat 8. Should the flame be extinguished by any means whatever and the gas permitted to es-' cape through the burner, the thermostatic strip 22 would contract and the trigger 23 would move away from the arm 13 and permit the latterto assume a position to seat the valve-head 18 upon its seat 8 and stop the flow or escape of gas. This effect is due partially to the contraction of the valve-stem 15 and partially to the weight of the depending arm 13, added to which is the gas-pressure upward against the lower surface of the valvehead 18.
From the foregoing it will be obvious that my invention is comparatively simple in construction, can be manufactured at a light cost, is reliable and eflicient in operation, and is not liable to derangement in use.
Various changes in details of construction may be resorted to without departing from the spirit or scope of my invention. Hence I do not desire to be limited to the precise construction shown and described.
Having thus described myinvention,what I burning of the gas, and means for seating the valve when the gas is extinguished.
