GAS-BURNER ATTACHMENT.
To all whom, t may concern:
Beit known that I, JOSEPH D. SHEEHAN, a citizen of the United States, residing at 5413 Fourth avenue, Brooklyn, in the county of Kings and State of New York, have inventednew and useful Improvements in Gas- Burner Attachments, of which the following is a specification.
This invention relates to cut off attach-- ments for gas burners,` designed particularly for use with gas burners carrying incandescent mantles.
The objectsof the invention are to improve and simplify the construction of such devices; furthermore, to increase their etlieiency in operation, and to decrease the eX- pense attending their manufacture.
,With the foregoing and other objects in ,view which will appear as the description proceeds-the invention resides in the combination and arrangement of parts, and in the details. of construction hereinafter described and claimed as a practical embodiment thereof.
ln the accompanying drawing forming part of this speciiication,-Figure 1 is a vertical sectional view, partly in elevation illustrating the invention, the valve being shown 33 is formed with a s mall passage 34 which terminates at its upper end in a cone shaped valve seat 35. Surrounding the upward eX- tension 32 is Ia burner section 36 having air inlet holes or openings 37 which are disposed below the upper end of the plug section 33. Mounted in anysuitable manner upon the upper end of the burner section 3G is a collar 38 to which is secured in any suitable manner a large burner section 39 on which the incandescent mantle 40 is supported in any convenient and well known manner. Supported within the burner section 39 by means of braces 41, is a cylinder 42 having an open lower end. Mounted within the cylinder 42 is a piston 43 through which extends a piston rod 44 having on the lower end thereof a cone shaped valve 45 adapted to lit into and close 4Specification of Letters Patent.
Application filed August 21,1905.v
gas to Patented April 23, 1907. Serial No. 275,190.
the valve seat 35. f ..`=fThe piston rod 44 is provided With a laterally extending arm 46 which isadapted-.to be engaged by a cam member 47 havin la handle portion 48 projecting outward t ough the burner section 36, and being pivotally mounted as indicated at 49. Formed inthe upper end of the cylinder 42 is a cone shaped valve seat into which is fitted a cone shaped valve 50 having a valve stem 51 extending through a bracket or guide-arm 52 mounted upon the cylinder 42. Extending through the valve 50 and stem 51 is a small air passage 53.
The piston rod 44, above the cylinder 42 is formed of brass or-copper and is bent at its upper endv as indicated at 54. Secured. to the upper end of-theepiston rod 44 is a strip 55 of steel or other metal having a lesser degree ofexpansibilitywhen subjected tothe action of heat,.tl ian the metal-of which the upper end of the piston rod is formed, IThe strip 55, therefore, Ain combination with the upper end of thcgpiston rodse'rves toproduce a thermostat which isjadapted to be flexed by the action of heat, from the straight positionshown in Fig.- 2, to the curved position shown in Fig. 1.
Constructed as described, the device is op'- i erated in the following manner ;-The cut-off 31 is opened, and the cam member 47 is raised by hand, soas to elevate the piston rod 44 from theposition illustrated in Fig. 2 to the position illustrated in Fig. 1. As the piston 43 moves' upward in the cylinder 42, the valve 50 is raised so as to permit the escape of air from the upper end of the cylinder. As soon as the Vpiston has reached the limit of its upward movement, the valve 50 drops back into position to 'close the upper end of the cylinder. As the piston 43 attempts to descend, air is forced to enter through the small passage 53, for which reason the descent of the piston 43 and consequontly the valve 45 is retarded fora suflicient length of time to permit a quantity of plass through the plug section 33 and enter .t e mantle 40,lv where the same is ignited by a match held in the vicinity thereof in the usual manner. 'As soon as the mantle is properly ignited, the action of the heat causes the thermostat at the upperend of the piston rod 44 to flex or bend in such manner as to'engage a brace 5.7 which is arranged across the upper end of the burner section 39. As soon as the thermostat engages the brace 57, the valve 45 is held in elevated position IXO . construction as 'well as thoroughly elicient as long as the mantle-remains properly ignited. In the event that the gas su ply should fail, the thermostat would coo oil? and assume the straight positionshown in Fig. 2, so 'that the piston rod 44 would descend gradually by gravity and cause the valve 45 to close the valve seat 35 and prevent the escape of gas. l
The improved device or' this invention is strong, simple, durable and inexpensive in in operation. p
Changes in the precise embodiment of invention illustrated and described may be made within the scope of the following claims Without departing from the spirit of the invention 'or sacrificing any of its advantages.
Having thus described the invention what is claimed as new is 1. The combination of a gas supply pipe, al plug section therein having a valve seat, a small burner section `surrounding theI plug section and having air inlets disposed below the valve seat, a large burner section coni nected with the small burner section and having braces therein, an air cylinder supported by the braces and having the lower end thereof open, a one-'way valve in the upper end of l the cylinder, having a small passage therei through, a piston located in the cylinder, a l piston rod extending through the piston and l cylinder, a valve on the lower end of the piston rod, a thermostat on the upper end of the iston rod, and a brace extending across the arge burner section and being adapted to i be engaged by the thermostat, substantially as described. p
2. The combination with a gas supply pipe formed 'with a valve seat, a burner seetion arranged above the valve, a thermostat movable within the section and carrying a valve to cooperate with said seat, means for manually operating the thermostat -to unseat the valve, and means to retard the gravitation of said valve to closed position when released from the manual operating means, said retarding means including an air cylinder having a valved inlet at the upper end, and a piston disposed Within said cylinder and connected to the thermostat.
3. The combination with a. gas supply pipe having a valve seat, a burner section above the valve seat, a thermostat movably supported 'within the burner section and carrying a valve to engage said seat, means for manually operating the thermostat to unseat the valve, means for automatically retarding movement of the thermostat when released from the manual operatmgmeans, a
'- stop supported within the burner above the upper end of the thermostat in normal position, and a projection carried by the thermostat to engage said sto in the movement'oiI the thermostat under t 1e influence of heat.
In testimony whereof, I have affixed my vsignature in presence of two witnesses.
