EDWARD F. DEBLEY, OF PORTLAND, OREGON, ASSIGNOR TO GAMPBELLS AUTOMATIC SAFETY GAS BURNER 00., OF PORTLAND, OREGON.
SAFETY GAS-BURNER.
. Specification of Letters Patent.-
Patented Sept. 10,1912.
To all whom it may concern:
Be it known that I, EDWARD F. DEBLEY, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Safety Gas-Burner, of which the following is a specification.
This invention relates to improvements in safety gas burners, the same being a valve construction adapted to be disposed adjacent to the burner and operably connected with a heat expanded medium, whereby when the gas is burning the heat from the flame thereof will so actuate the eXpansible medium as to permit the valve to be retained in open position the failure of the flame due to any known or unknown reason and the consequent cooling of the eXpansible medium automatically actuating the control valve of the burner so as to shut off the gas and prevent the escape thereof.
A further object of the present invention is the provision of a casing adapted to be connected to a gas supply pipe and carrying the ordinary form of gas tip or burner tube, said casing having operably mounted therein and disposed between the gas supply and the gas emission portion of the casing, a spring closed sliding valve adapted to be manually actuated into gas emission position in combination with a locking mechanism thermostatically controlled, to lock the said valve in gas emission position and retain the same during the burning of the gas, the heat from the flame actuating said thermostatic medium to permit such action, said thermostatic medium being so disposed that for any reason should the flame be extinguished, the lowering temperature of the surrounding air will cause the contraction of said thermostatic medium so as to release the valve lock and permit. the said valve to automatically close and thus prevent the escape of gas through the burner.
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, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings-Figure 1 is a longitudinal sectional view through the complete valve casing which is adapted to be connected to any form of gas fixture or gas supply and to carry the gas burner, the thermostatically controlled device being shown foreshortened. Fig. 2 is a sectiontaken on line 2-2 of Fig. 1. Fig. 3 is a front elevation of the complete valve mechanism. Fig. 4 is a rear elevation thereof.
Referring to the drawings, the numeral 1 designates the main casing or body of the valve which is provided with the boss 2 pro vided with the interior threads for connection of the valve casing or body to the supply pipe of a gas system. Leading from the boss 2 into the body of the valve casing is the gas supply duct or channel 3 which is disposed in line with the duct or port 5 formed in the frame 4 which is disposed to guide the sliding gas control valve 21 as will presently appear.
Mounted in the open end of the casing is a disk 6 the same being held properly and in gas tight relation thereto by means of the locking ring or collar 7 Mounted concentrically of the said disk 6 is a screw 8 carrying the adjusting or abutting pin 9 which is disposed in the path to limit the movement of the finger 10 of the pivoted lock actuating double pointed lever 11, which is pivoted at 12 between the parallel strips 13 formed integral with the interior lower portion of the said casing or body 1. The terminal 14 of the'double pointed lever 11 is inclined upwardly and disposed in operable relation at all times with the curved shoulder 15 of the valve lock or trigger 16, said valve lock or trigger being provided with the rearwardly extending pointed projecting end 17 so that the movement of the hooked end 18 thereof may be limited due to the contact of said portion 17 with the upper under surface of the valve casing or body 1. This valve engaging trigger or look 16 is pivoted'by means of a pin 19 within the casing or body 1 so as to be operably disposed at all times with relation to the double lever 11 and the projecting portion 23 of the sliding bar 21. By means of the spring 20, the tension of the trigger 18 is at all times toward the shoulder or projection 23 of the valve so that the same when in gas supplying position will be locked to assume the position as clearly shown in Fig. 1.
As before stated the valve 21 is a block disposed to slide upon the lower surface of the valve body 1 and between and below the portions of the frame 4, thus insuring the proper longitudinal movement of the same so that its port 22 may be placedin alinement with the ports 3 and 5 to permit the gas to flow from the gas supply pipe (not shown) into the valve casing. In order to operate the said valve and to cause the same to move from its gas cut off position, that is when the lug 23 is seated within the recess 21 of the casing, a stem 25 is connected to the valve and extends outwardly through the reduced portion of the casing or body 1 carrying upon its end the actuating button or knob 26 with the interposed coiled springs, which normally tends to hold the valve toward closing or outward position.
Formed integral with the casing or body 1 is the burner carrying tube or boss 27 which is provided with the gas emission port 28.
In order to control the double pointed lever 11. so as to permit the spring actuated lock or trigger 18 to engage the valve to hold the same in the position as shown in Figs. 1 and 2 or to release the same to permit it to close the supply of gas and prevent the escape thereof through the port 28, there is disposed within the reduced threaded boss 29 of the body or casing 1, an expansion tube 30 which has mounted concentrically therewithin the double lever controlling rod 31 whose upper end 32 is disposed in the extreme end of the expansible tube 30, said tube 30 forming a thermostatic means to be disposed to be affected by the heat from the flame when the burner is ignited to cause the longitudinal expansion of the tube 30 and permit the vertical movement of the rod 31 so that the lower end thereof will permit the said double lever 11 to assume the position as shown in Fig. 1, at which time the terminal 10 is against the abutment 9 and the trigger actuating terminal 14 is resting lightly upon the curved abutment 15 of the trigger 16.
Then the flame of the burner has been extinguished for any reason, the cool air will cause the contraction of the expansible medium or tube 30 and thus move the rod 31 so that its lower end will be pushed downwardly into engagement with the double le ver 11 at the point around its pivotal end 12 toward the valve 21, thus depressing the terminal 14'to slide upon the curved abutment 15 of the trigger 16 and to cause the hooked end 18 thereof to be raised and thrown out of engagementwith the projecting portion 23 of the valve 21, thus permitting the spring S to exert its tension against the button or knob 26 and move the valve from the full line position as shown in Fig. 1 so that the projection 23 will be seated within the recess 24- of the casing or body 1 and the port 22 out of registration with the res )ective ports 3 and 5. By this means the few of gas from the supply to the burner will automatically be extinguished without the necessary manual control for the valve as is now generally used.
hat is claimed is:
1. A safety gas burner, having a valve casing provided with a gas supply and a gas emission port, a spring closed valve mounted in said casing to control the supply port, a spring released trigger within the casing disposed to engage said valve to lock the same in open position, and a thermostatically controlled means disposed to retain the trigger in locked position during the burning of the gas and to be released due to the extinguishment or falling temperature exerted upon the thermostat.
2. A safety gas burner, having a valve casing, said valve casing being provided with a gas supply connection and a burner connection, a valve guiding yoke mounted therein provided with a port adapted to aline with the gas supply port of the casing, a slidingly mount-ed valve mounted in the casing within said frame and provided with a port adapted to be moved in registration with the supply port and port of the frame, a spring for normally holding the valve with its port out of registration with the supply port and port of the frame, a spring actuated trigger for engaging the valve and holding the ports in registration, a lever disposed within the casing and'operably connected to said trigger, and thermostatically controlled means connected to and project-- ing within the casing for actuating said lever to lock the valve or permit the automatic closing thereof.
In testimony that I claim the foregoing as my own, I have hereto aflixed my slgnature in the presence of two witnesses.
EDWARD F. DEBLEY.
