Be it known that l, JOHN Hamrr lim nson, a citizen of the United States and a resident of Terre Haute, in the county of Vigo and state of Indiana, have invented certain new and useful Improvements.in tia fetyAttachments for Burners; of which I .the followingis a specification. H
invention relates to improvements in 1 safety attachments for burners, especially.
gas burners forstoves, lamps, and the like,
i Q and it consists in the constructions,wco1nbi nations and modeof operation herein described and claimed.
4 One ()ftheforeroost (ibjects of the invej 1 tion is to provide a'gsirnple b'l tn liahle ventsthe escape of gas or other fuel from a the burner unless such fuel 1s. ignited} 13:1; A further j objject of the invention. is to provide 'a safety attachment, for burners s whlch involves the necess ty. of applying a A. further obj ect of the invention 1 is to provideasafety"attachmentufon burners in whlch the gas valve is held open by instru- 9 rnelntalities which (are rendered iactive by wheat radiatingifromwthe burner.

Figurefi is a detailperspective.vieW of the rubber diaphragm, and i perspective: view of thevalve lifter. v
1 lit is the purpose of the inventionto make use of heatforr establishing andmaintaining a fiowof orotherxfuel toaburner. It is 5 5necessar to apply a. lighted thatch toanexpander before a ball check valvewill raise to letthe pass to aburner. It is also necessary to open the 11121111 gas valve in order to establish a flow of gas in thefirst place. The expander is carried-by a part of the valve and the former is automatically adjusted in relationship to the burner in accordance with the amountof opening of the main valve. Consider the diagram in Figure 1, which is a development of the safety attachment clearly illustrating the operation. The main gasvalve 1 is opened by turning the handle 2 (Figures 2 and 5) so that a flow. ofgas is established in the pipefi Which leads to the top of the main chamber 4 of the controller, Where .it is. stopped by the ball check valve The plug of the gas "valve carries a lever 6.
Asthe gas; valve 1 is opened, the lever 6 raisesa crosshead]? the leirer having a bent end .8 which operates 1n a horizontal slot 9 i in the crosshead; The latteris guided by vertical rods 10 and there is sufficient 'fIlC-px tion between the vertical guides and the crosshead to maintainthe latter inanv ad justed position. This function is also aided bvthe friction ofthe plug in the gas valve.
1 w The crosshead 7 carries a steel tube 11 Whiclr'is surmountedby the expander 12.
Theexpander consists of a closed ran containing alrl Assume the expander 12 to be in the positionillustrated in Figures 1 and 3, l
at vvhich time the main valve is opened j.

seat l? andestablishing the flow of gas from the pipe fi to the burner B. The gas is compensated for by the reduction in spacebet-ween the burner and the expander. the result being substantially that obtained hetore, namely the air in the expander column is kept heated and the valve 5 is kept elevated.
The diagrams in Figures 3 and a illustrate the'adjustiuent oi the expander 12 in relationship to the burner B in proportion to the amount oropening of the main gas valve. The amount of? travel of the expander equals the radiusol the lever 6 which is made to assume its extreme position in a vertical line by turning the handle 2 from its normal rest position rip it ales to the left of the pipe to a similar right angular position at the right of the pipe 3. l Vhen the handle 2 is in the first position. the crank 6. crossliead 7 andexpander 153 are at the extremity of their lowermost movement s an'd'the valve 1 is closed. When these parts are moved to approxi. .ately the mid position (Figure the valve 1 is wide open. and when the handle 2 is moved to the latter position the crank 6 crosshead 7 and expander '12 are at the upper extremity of their movements. again closed.
In addition to the parts described above. thecontrollere has a circular base 17 from which stems 18 depend (Figures 1 and Themain valve '1 is then forithe purpose of supporting a volrc 19.
This yolre has a boss in which a screw 20 is threaded for the purpose of holding the supplementalichamber 14: in place. I
.ThlS supplemental chamber comprises a short section of glass tubing (Figure 5) which engages rubber washers it both edges, for the purpose of making ens-tight joints. The upper washer is seated in a recess in the bas 17. The lower washer is seated in a recess in the entrance plate 22 which includes the chamber 23 to which the heated or expanded air'from the expander 12 is admitted.
The screw 20 enables removing the entrance plate 22 and its carried parts, so that the diaphragm or balloon 13 may be renewed. The rubber of which this diamade dries out intime so that it requires to be replaced. Figure 6 shows one of the diaphragms in place on the entrance plate. The diaphragm includes a metal base 24 which is screwed in place onthe threaded stud 25 in the center of the plate 22. In order that access may be had to the ball valve 5, lifter l6, etc. the controller 4 is'made in sections as sho n in Figure 5.
The various parts are unscrewed for the purposed'escrlbed. The stove to which the.
quantity of heat.
Fuel to a bu improved safety attachment is applied, is shown in a conv, itioi'ial manner in Figure r. but may be briefly described as comprisino up} er and lower tables and 27. The r a 28 separate the tables and rods support ti e burner structure. The table 26 furnishes a hearing or guide for the vertically movable steel tube 11. The table 27 furnishes a base for the guide 10.
