Y GAS-BURNER AND Au'romA'rlc OUT-OFF THEREFOR.

To all whom it may concern.-

Be'it known that I, LE HOLTSCHNEIDER, a citizen of the United States, residing at Jefierson City, county of Cole, and State of Missouri, have invented a certain new and useful Improvement in Gas-Burners and AutomaticCut-Ofl's Therefor', of which the following is a specification.

My invention relates to a new and useful improvement in gas-burners and automatic cut-oifs-therefor, and has for its ob'ect to provide an exceedi ly simple and e ective device of this description which absolutelyprevents the escape of gas ii -quantities sufficient to do damage should the light become extinguished.

-With these ends in view this invention consists in the details of construction and combination of elements hereinafter set' forth and then specifically designated by the claims.

In order that those skilled in. the art to which this invention appertains may understand how to make and use the same, the construction and operation will 110w be described in detail, referring to the accompanyg drawings, forming a part of this specification, -in which Y Figure 1 is a section of my improved burner; Fig. 2, a vertical section thereof, taken at the line a: a: of Fig. 1; Fig. 3, a section at the line y y of Fig. 1; Fig. 4, a detail view of. the base, a portionofwhich is sectioned away; Fig. 5, a lan view of said.base; Fig. 6, a detail view 0 the thermostat.

-In carryi out my invention as here-embodied, A rd p nesents the base, rovided with the screw-threads B for attac ent to the gas-fixture in the .usual manner," and C is the pillar, whichis adapted to fit-over the base 'and secured thereto by means of the setscrew'D. The base hasformed in its upper end a concave recess E, and an opening F passes through-this concave section slightly to one side of the center-of the base for the p osehereinafter set forth.

I' l he groove G is formed around the base, and ahole H leads from said groove .to-t-he interior thereof in order thata smallamount .of gas may flow-from the interior of the base to this oove and from thence throu h the passage to reach the interior of the p' ar Q, 1

a and I tprovide a reg'ulating-screwil, the inner end 0 which; approximately fills the cross- Specification of Letters Patent. Application filed April 27,1906 Serial No. 313,935.

section of this passage I, so that by adjust' said screw more or less gas will be permitte to flow through said passage.

K is a ball, made ofany suitable material,- placedu on the concave surface of the base." This ba normally rests over the opening F, thus closing the principal flow of thegas from the base ,to the pillar. i

L is a thermostat, which is made of two metals of different expansive properties, such natesin-the plate M, which is of some material that readily absorbs heat, and this plate is secured in the tip-N, the latter being of a material of low heat-conducting power, having a slot 0 for the issuance of the gas for forming the blaze. 1 i Whenl he gas is shut ofl at the stop-valve, the ball will rest upon the ogening F; but when the gas is turned on the st action will be for a small portion to flow' through the pillar and from t ence escape through the slot 0, from which point it may be lighted, and the burning of this small flame will transmit suflicient heat to the plate M to so afiect the thermostat as'to cause it to force the ball from off the opening F, thus allowing the Y full flow of as to reach the slot 0 and produce the size l'flame. become extinguished accidentally, the immediate cooling of the thermostat will permit the'ball to again close the passage F thereof, shutting as the main flow of gas, the only escape being through the hole H and passage I, which is not suflicient to. do any damage.

Should the hght' i The construction of the thermostat is such that it is self-compensating, so that the lower end is the'same distance fromthe ball in either warm or cold surroundings.

The action of the tlfermostat u on the around the base, fwhich'may be accomplished ball may be varied byadjusting t e pillar 2 eaneoo by backing ofi the set-screw D and resetting it when the proper adjustment is had, it bemg understood that the turning of the pillar relative to the base willvary the position of the opening F relative to the lower end of the thermostat, and as the ball normally rests over this opening it follows that its normal position will also be varied relative to the lower end of the thermostat and this adjustment will cause the thermostat to act more quickly upon the ball.

P represents the sponge or other suitable material located the base for filtering the gas in its passage to the pillar.

Having thus fully described my invention, what I claim as new and useful-is- 1. The hereirrdescribed combination of a base threaded for application to a gasfixture, said base having an upper concave surface and an opening through said surface 05 the axial line, said base also having a groove around its circumference and a hole leading from the interior thereof to said groove, a pillar adjustably fitted to said base, means for holding said pillar in any adjustment; said pillar having a passage-way leading from the groove in the base to the interior of the pillar, a regulating-screw, the end of which crosses sald passage, a ball adapted to normally close the openin in the concave sur face,fa-tip secured to t e pillar, said tip being of low-heatconducting material, a plate of high-heatconducting material secured to the tip and a thermostat consisting of two kinds of metal of difierent expanding qualities.

,2. In combination with a burner of the character described, a thermostat consisting of a plate of high-heat -cond ucting qualities and two strips of metal of difierent expanding qualities extending side by side .for a certain distance and then being reversed for the remainder of their length, as and for the purpoes set forth.

3. in combination with a burner of thecharacter described, a base having a con- .caved upper surface and, a hole formed through the same, a ball adapted to rest upon the concaved surface and close the hole therethrough, a thermostat consisting of a highheat-conducting plate secured to the tip of the burner and two metal strips extending downward from said plate lying side by side LEO HOLTSCHNEIDER.
