GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 643,320, dated February 13, 1900.

Application iiled November 15, 1899- Serial No. 737,008. (No modell) To all whom t may con/cern:

Be it known that I, FRANCIS J. BYRNE, a citizen of the United States, and aresident of. NevT York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specication.

The invention relates to improvements in gas-burners, and particularly to gas-burners equipped with automatic igniting devices.

My invention has special reference t'o means for automatically controlling and regulating the flow of the gas through the burner: so that when the gas is turned on only a light-howof the gas shall issue from the burner until, due to the heat of the flame after the gas has 4been ignited, certain mechanical features,

hereinafter described, are set in motion to more fully open the discharge through the gas-burner and move the igniting substance from the sphere of the flame.

While the invention is not confined to the special character of igniting substance employed for automatically lighting 'the gas when the latter is turned on, I suggest the employment of a body containing nely-di vided platinum held by means which, after the gas has been ignited, carries the said body from the sphere of the name. Great diiiculties have been encountered in successfully using automatic igniting substances such as above indicated, it having been found that in many instances the said substancesfail to ignite the gas. After continued study and experiment I have discovered that the action of the igniting substance becomes effective under a light pressure or flow of the gas when it is not effective under a normally-strong gaspressure, and in giving effect to this discovery I provide means in accordance with my present invention which will only permit of a light iiow of the gas until the latter has'been ignited and will then permit a free and full flow of the gas for maintaining the permanent flame for adequate illumination.

My invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a central vertical section through a gas-burner equipped with my invention and the dotted line 3 3 of Fig. 2 and illustrates more particularly the means for supporting the igniting substance, effecting the movement of the latter from the flame,and causing 6o the full opening of the passage through the gas-burner. Fig. 4 is an enlarged central vertical section of the regulator embodying my invention and when in use located within the gas-burner and connected with a movable part of the igniting devices, said regulator normally nearly closing the 4passage through the burner, but moving upward after the flame has been ignited to fully open the passage through the burner; and Fig. .5 is a 7o horizontal section through the burner and regulator on the dotted line 5 5 of Fig. 1.

In the drawings,` 10 designates the gasburner, screwed upon the nozzle or 'pipe l1 and receiving a sleeve 12 of the bracket 13, 75 which supports the pivoted lever 14, carrying the igniting substance 15, and also the lever 16, Awhich is operated by the expansion and contraction of the German-silver or other metallic bar 17, the latter at one end being se- 8o cured to a rigid part or arm of the bracket 13 and at the other end being pivotally secured to the short, arm of the lever 16, which is piv- Aotally secured to the said bracket 13 and engages a socket 18 formed in said lever 14, as 85 more clearly illustrated in Fig. 3. The lever 16 is guided in its movement by an arm 19, which is in one integral piece with the bracket '13 and turned over in close proximity to the outer face of the lever 16 and lever 14, as illus- 9o trated, said arm 19 serving to preserve the

levers

14 and 16 in close proximity to the vertical face ot"H the bracket 13. The igniting substance 15 may be of any suitable character; but I suggest the employment for this purpose of a piece or body composed of substantially equal proportions of sand and pulverized asbestos, incorporated with a sufticient quantity of a saturated solution of plati'nic chlorid to bring the mass to the consistroo ency of putty. The piece or body formed as described should be wrapped tightly with asbestos fiber and wound with fine platinum wire and then dipped in a dilute solution of platinic chlorid and dried. The platinic chlorid may be reduced to metallic platinum in any suitable manner. I do not claim to be the inventor of the igniting substance 15, nor do I claim to be the inventor of said substance when combined with a movable lever or support 14, said

features

14 and 15 being well known in this art. The substance 15 is held between arms or jaws on the upper end of the lever 14, and said lever is capable of pivotal motion, so that said substance 15 after the gas has been ignited may be moved away from the flame thus formed according to known methods.

My invention comprises the combination, with other features, of the regulator 20. (Shown on an enlarged scale in Fig. 4 and on a reduced scale in position within the burner in Fig. 1.) The regulator 20 is preferably made of lava and comprises the hollow tubular stem 21 and the head 22, the latter being capable of being freely moved vertically within the chamber 23 of the burner 10 Without contacting with the walls of said chamber. The stem 21 of the regulator 20 is preferably hollow and provided with outlet-apertures 24 at its upper end for the passage of the gas. The stem 2O is guided by the walls of the aperture 25,formed in the upper end or top of the nozzle or pipe 11, said end or top being closed except at the aperture 25, which is recessed, as at 26, to permit of the passage of the gas. When the regulator 2O is in its lower position, its head will nearly seat upon the upper end or top of the pipe 11, and at such time only a limited quantity of the gas will pass below and around the same to the tip of the burner. Vhen the regulator 20 is elevated, the gas in a full free volume may pass around it, the gas being permitted to ascend through the recesses 26 and stem 21. The regulator 20 is connected by a wire 27 with the frame holding the iguiting substance 15, said wire passing up through the burner 10 and out through an aperture 28 in the burner-tip, as shown in Fig. l. When the lever 14 and igniting substance 15 are in their normal position, (shown in Fig. 1,) the regulator 2O will be in its lower position, nearly closing the passage for gas through the burner, and when the gas is turned on in the usual manner the restricted flow of gas will pass against the substance 15 and become ignited, and thereupon the flame will heat the bar 17, the latter being thereby expanded longitudinally and causing the long arm of the lever 16 to move against the upper wall of the socket 18 of the lever 14 and turn said lever outward, thus causing the lever 14 to carry the substance 15 outward from the flame and also to pull upward on the wire 27 for the purpose of elevating the regulator 2O sufficiently to permit the full normal fiow of the gas around the same. The bar 17 will remain expanded or extended as long as the flame is in existence, and hence during all such period the substance 15 will remain away from the liame and the regulator 2O will be maintained in its elevated position. Thus only a restricted flow of the gas is permitted until the ignition has taken place, and then under the influence of the heat generated by the flame the bar 17 extends to actuate the lever 1G and cause the latter to move the lever 14 for the purpose of removing the substance 15 and freely opening the passage through the burner 10, whereby the full ow of gas is permitted and the proper degree of light is secured and maintained. With the primary restricted flow of the gas the ignition, under the action of the substance 15, is assured, whereas with a full fiow of the gas without regulation the substance 15 will very frequently fail of its purpose.

With the employment of my invention the gas will, when it is desired to use the same, be fully turned on at the cock in the usual manner and thereafter the operation of the .burner and its parts will be automatic, the

ignition first taking place and then the substance 15 moving outward and the regulator.

2O elevating.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The gasburner, and the igniting substance arranged to meet and ignite the gas as the latter issues from the tip of said burner, combined with the regulator for controlling the amount of gas flowing through said burner to said tip and forming a permanent passage for the gas to said tip, and means for automatically operating the said regulator to permit a more free iiow of the gas to said tip after ignition has taken place, said regulator normally only permitting a restricted fiow of gas to said tip until ignition has taken place and then permitting a free ow of gas to said tip; substantially as and for the purposes set forth.

2. The gas-burner, and the movable arm carrying the igniting substance, combined with means for moving said arm to carry the said substance from the fiame, the regulator to control the flow of gas, and means connecting said regulator with said arm whereby after ignition has taken place and said arm is moved, the said regulator will be thereby actuated to permit a free flow of the gas; substantially as set forth.
