'b all-whom it muy concern:

vBe .it known that l, CLARENCE HOFFMAN l-IERR, a citizen of the United States, and a resident of Phil-adelphia, Pen11sylvania,have invented certain new vand useful Improvements in Gas-Stove Regulators, of which the following is a specification.

My invention relates to that class of stoves in which there is a support for a burner supplied with a proper combustible mixture and where it is necessary to reduce or extinguish the flame when utensils are not on the stove, und to this end my invention consists of means whereby the control cosl( is vshifted from a controller supported by a counterweight, as fully set torthhereinater and as illustrated in the accompanyinggy drawing, in which:

Figure l isa sectional elevation of a gas stove embodying my improvement; and Fig. 2 a lan view.

The gas burner A, of Vsuitable construction, has combined therewith a mixing tube B, opposite to which is any7 suitable form of nozzle 2, to which gas is supplied through a main pipe C.' This nozzle is part of a fixture l), which includesl the seat for a cock 3 used for turning the gason and off the burner, and-an auxiliary Valve Ll, which is shifted by the action of a controller E, so that when the controller is in one position the gas is turned on to the main burner, and in another position the gas is cut ol theretroni.` Intermediate the valves 3, et, there is a port 5, with which to connect a pilotlight pipe 6, the latter extending to or communicating with a channel extending to a point adjacent to the main burner, and as this port 5 is back of the valve l and in 'constant free communication with the main pipe, when the cock 3 is open the gas will always flow through the pilot-light channel, and the pilot light may be constantly mainln order to elilectively construct. these parts l prefer, as before stated, to pro- .vide the I'ixture l) with the seats for both valves so that this fixture may be applied in connection with ordinary forn'is-ot' mixing4 tubes and arrangement of main pipes, .and to prevent asfar as possible any possibility. of breaking the pilot-light connection l pre- Speeication of Lettere Patent.

Application tiled March 10, 1908.

Serial No. 420,262.

fer to extend the channel y through enlargements or ribs 7, 8, cast upon the casing which includes the burner and main section of the mixing tube, and to bore or otherwise form the channel in these portions, the forward end Ot' the channel being threaded or socketed at 9 for the reception of the free end of the pipe 6.

To prevent the extinguishing of the pilotlight by a draft of air through the central Opening ru of the burner, and also to prevent the small opening of they pilot-light becoming clogged by the dropping of grease l cover the pilot-light channel by means of a cap 10, preferably formed by so constructing the parts that the channel is curved downward at the upper end as shown. The arrangement of this channel also inside the burner and adjacent to the latter insures that the portion of the channel where the opening is situated shall be .submitted to an intense heat so that any particles of vfood or other matter dropping onto the burner at this point will be certain to-'be consumed and prevent any possible extinguishing of the pilot light, thereby preventing the result-s which would arise in case the light was extinguished without turning off the gas.

The controller E is centrally arranged and has radial arms l2, which are curved downward from the center and the parts are so supported and arranged that the ends of these arms shall not` project above the inward projecting arms 13 of the grid F, and as a result ot this constructionthe deposit of any vessel upon the stove, either directly downward or by shoving it laterally will have no tendency to strike and deect and break the controller. The controller is wholl y supported on and guided. by lever G, pivoted to a support l5, adapted for attachment to the bracket 16, which usually supports the burner i'i stoves of this character, and has at the'outer end a counterweight l?, sufficient to counter balance the part l5 and to normally maintain it in its lifted position and also to operate the valve 4, when the vessel is removed from the controller. Suitable connections extend between the controller and the valve. As slnnvnrth.I valvefis provided with an arm ranged so flame, and any particles, such as bread or 18, and an arm 19 extending from the burner casing supports the pivot o a lever 20, one arm of which is connected to a rod 21 on the upper end of which rests the hub at the center of the controller E, while the other arm is connected by a rod 22 to the end of the arm 18 of the valve Ll. These parts are so arranged that when the controller is in the normal position shown in the drawing, it is held therein by the weight 17, and the valve 4 is closed, the gas however passing freely to the pilot-light opening. l/Vhen a vessel is placed upon the controller it-is depressed and thereby swings the lever 20, and arm 18, and turns the valve 4:, turning" the supply of gas from the burner.

These parts, constructed as above described, have been devised with a view of meeting the exigencies of an apparatus of this class, the controller E being so supported without Vbearings or slides that in case it shall warp from th'e effects of heat, there will be no friction resulting upon its supports, while the connecting rod 21 is arthat it will be subjected to the pieces of meat, which may drop downward vwill be burned and thus avoid interference with ,the operation of the controller, and there is in no case any clogging or obstruction of the operating parts. Further it will be seen that l haveavoided the use of springs which experience has proved to be detrimental in any kind of control arrangement for gas stoves.

An important feature of 'my above described construction is the connecting o the controller andfthe arm of the valve 4, through the medium of a horizontal ynonneet-ing rod 22, and adjuncts, Yas described. ,-9

By this construction I am enabled to adapt the parts of my apparatus to the burners arranged at dilerent points of the stove, simply by varying the' length of the connecting rods 22, the parts connected with the burner at the back of the stove being precisely the saine as those with the burner at the front, except that the connecting rod 22 in such case is longer.

It will be seen that the parts connected with the controller are all arranged below the supporting grid F, so as to be entirely out of the way of the cooking utensils, except tov the limited extent to which the center of the controller is permitted to occupy a position above the rid.

Wit-hout limiting inyse to the precise construction and arrangement of parts shown and described, I claim as my invention:

The combination with the grid burner Yand valve of a gas stove, of a controller arranged within the grid and above the burner and provided with downwardly extending curved arms, a lever pivoted below the grid and connected rigidly to the controller, a counterbalance .tor said lever, a rod extending centrally downward from the controller, and wholly supported thereby,

and positive connections between the rod 7 and valve.

In testimony whereof I' athx my signature in presence or two witnesses. v
