J SLADKY ET AL TEMPERATURE ACTUATED AUTOMATIC CONTROL VALVE I El/114 274 WWW T Filed Oct. 8, 1928 ova w? Patented June 7, 1%32 unites STATES rarest series JOSEPH SLADKY AND ALEXANDER, C. SLADKY, OF ZMILXVAUKEE, WISCONSIN, ASSIGNOB-S TO NATIONAL ENAMIELING- & STAMPING CO., INC MILWVAUKEE, WISCONSIN w TEMPERATURE AOTUATED AUTOMATIC CONTROL VALV E Application filed 0ctober 8, 1928. Serial No. 311,229.
This invention relates to temperature ac.- tuated automatic control valves.
In gasoline stoves, it is the practice to heat the generator tube to generate the gas for the burner by any suitable means prior to allowing the fuel to pass to the burner. It sometimes happens through carelessness, or other causes, that the. fuel is allowed to pass to the burner before the generator tube is sufficiently heated, with consequent flooding and sometimes with serious results.
This invention is designed to overcome the defects noted above, and objects of this invention are to provide a temperature actu- 5 ated automatic control valve which is applicable to the control of gasoline stovesand to other analogous uses, and which is so made that it is necessary to heat the generator tube and an associated member before gasoline or other fuel can pass to the generator and main burn-er, so that there is no possible chance of flooding the burner or, in other words, allowing the fuel to pass thereto before the generator tube has been sufficiently heated.
Further objects are to provide an automatic device which functions without any thought on the part of the operator, which is relatively simple and easy to install, which is so constructed that an expansible liquid or gas, which will hereinafter be referred to as fluid, is employed to actuate a control valve for the fuel flow so that when a sufficient temperature has been obtained, the fluid will expand and actuate the control valve to permit the passage of fuel, and which will close the valve if the main burner goes out.
An embodiment of the invention is shown in the accompanying drawing in which: 7
The single figure is a diagrammatic View showing the device associated with a gasoline burner and with the priming cup.
It is to be distinctly understood that although this invention is described and illustrated as applied to gasoline burners primarily, that nevertheless it is of wider scope and the description and illustration are in tended merely to show one embodiment thereof. For instance, it may, obviously, be applied to gas burners.
Referring to the drawing, it Will beseen that a generator tube 1 is connected by means of a pipe 2 through the automatic device, to a supply pipe 3. The other end of the generator tube is connected to the burner 4. The generator tube may be provided with a hand control, as indicated at 5, in the usual manner.
Apriming cup or heating cup 6 is positioned below the generator tube and alsobelow an expansion chamber or device 7. This expansion chamber is connected to a head 8 which is screwed-into a casing 9. Between the head and easing, a diaphragm 10 is clamped. This diaphragm may be of metal, or any suitable material, and it may be other wise sealed with respect to the casing and head, than as shown in the drawing. At all events, a gas-tight joint is formed with the diaphragm, so that there can be no, loss ofinateria]. from the expansion chamber or member 7. h The member 7is provided with a' cylindrical extension 11 within which a guiding plunger 12 slides. This guiding plunger is provided with a reduced extension 13 which has a valve 14:. Thisvalve may be'conical, as illustrated, and may close the aperture 15 as indicated. From the valve, arod 16 extends to a head 17 whichbears against the diaphragm 10. A spring 18 urges the plunger and valve towards valve closing position, so that the valve normally contacts with the valve seat and cuts oil communication between the pipes 3 and 2, the pipe 3 extending to a gasoline supply tank. Itis to be noted that the diaphragm 10 also seals the device against leaking from gasoline, as it is in direct contact with the supplied fuel.,
The cylindrical portion .11 of the device may be closed by means of a threaded plug 19 which cooperates with a gasket 20 to seal the end of the cylindrical casing 11. The end of the plug bears against the outer end of the spring 18. i It is to be distinctly understood that-the showing is merelydiagrammatic and that the position of the burner may be altered, as desired.
It is shown in the position indi= cated in the drawing merely for the sake of clearness.
The mode of-operation of the apparatus is as follows:
Gasoline from any suitable source is conducted to the priming cup or heating cup '6, for instance, by means of a pipe 21. The gasoline in the cup is lighted and the flame heats the generator tube 1 in the usual manner. In addition to this, the member 7 is heated and the fluid expands and forces the diaphragm 10 to the right, as viewed in the drawing. This unseats the valve 14 and allows fuel to pass to the generator tube .1, which also has been heated from the fuel in the priming'cup or heating cup 6. 'The exact flow of fuel'required is governed by adjusting the hand wheel 5 inthe usual manner.
It will be seen, therefore, that no additional act is required on the part of the operator other than that of lighting the fuel in the priming cup in the usual manner. The device functions automatically and when a certain degree of temperature has been obtained for the gen-erator tube and, conse quently, for the expansion device, the automatic valve is opened and fuel passes to the generator tube and from thence to the main burner. Q I
It will be seen that inadvertent flooding 0f the burner before heating the generator tube cannot occur.
It is also tobe noted that in the event that the flame from the main burner goes out, that the member 7 will immediately cool off and the fluid contained therein will contract.
This will allow the automatic valve to close and cut off further supply of fuel to the There is thus no possible chance of damage, even in the event that the main burner flame should become extinguished.
The expansion chamber 7 is continually heated by the main burner under normal operations, and the valve isheld open. However,when the main burner is shut off, the expansion chamber 7 rapidly cools and the flluid contracts, thus allowing the valve to c ose.
Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be de' termined as claimed.
We claim:
The combination with a burner, a priming cup, and a generator arranged intermediate the burner'and priming cup communicating with the burner at one end, of a cylindrical erator tube opposite the end connected with the burner to the outlet nipple, a flared casing on the end of the cylindrical casing adjacent to the outlet, a diaphragm, a head clamping the diaphragmin the flared casing having a central opening, a tube having an expansible medium therein carried by the head and comwe have hereunto set our hands at Milwau kee, in the county of Milwaukee and State of Wisconsin. a
