CHARLES VAN DYKE HILL, OF ST. LOUIS, MISSOURI.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 781,879, dated February 7, 1905.

Application filed February 24, 1904:. Serial No. 195,099.

To (LU whom, it HI/[]] concern.-

Be it known that I, (/HARLESVAX DYK n HILL, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful lmprovement in Gas-Burners, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specilication, in which- Figure l is a top plan view of a portion of a stove provided with my present burner, certain of the parts being broken away in order to more clearly illustrate other parts. Fig. 2 is a vertical sectional elevation on about the line 2 of Fig. 1. Fig. 3 is a front elevation of the burner, partly in section, on about the line 3 3 of Fig. 2, certain of the parts being broken away. Fig. 4: is a rear elevation of the burner, and Fig. 5 is a detail sectional elevation.

This invention relates to improvements in gas-burners designed particularly for stoves, being more particularly an improvement upon the structure illustrated in Patent No. 751,793, granted to me February 9, 190st.

Among the objects of the present invention are to simplify the burner, the present device requiring but few parts, and thus being readily manufactured to provide for positive action of the parts, to provide a structure wherein but slight action of the vessel-controlled post is necessary, and to provide means for preventing grease and the like from clogging the seat of the said post, and thus interfering with the action of the latter.

To these ends and also to improve generally upon devices of the character indicated the invention consists of the various matters hereinafter described and claimed.

Referring now more particularly to the drawings, 1 indicates the frame of a gas-stove,

2 being the grille, and 3 the manifold with its needle-valve l for controlling the supply of gas to the burner 5. This burner is here shown as including two concentric rings 5 and 5". An air-mixing chamber 6 communicates with the burner 5 in a well-umlerstood manner, and a casing T connects said air-mixing chamber (5 and the manifold 3. This casing has a wall 8 extending across it and provided with a vertical bore 9 and with ports 10 and ll, the said port 10 communicating between the said bore and the side of the easing 7 whiclris toward the manifold and the port 11 communicating between said bore and the air-mixing chamber (5. This here 9 forms the valve-seat for the vertically-movablc valve '12, said valve being merely a short section of rod having the transverse port 13, which is adapted in one position of the valve to connect the ports ll) and ll, the valve 12 being normally in the positions shown in Figs. 2 and 5, whereby the ports it) and II are closed and the supply of gas is thus cut off from the burner. ln a hollow boss 14; upon the said casing T is seated at screw-valve 15, which controls the port 16 leading from the said casing T to the interior of said hollow boss. A pipe 17 leads from the interior of said hollow boss to a point in proximity to the gas-openings 17 in the burner 5, the end of said tube 17 forming a pilot-burner by means of which the main burner can be ignited in a manner which is well understood and also is explained in my said prior patent.

Extending across the space inclosed by the inner burner-ring 5" is a bridge-piece or connector 18, having a socket-piece 19 provided with a vertical bore or socket and also having a depending arm 20 provided at its lower end with a projection 21. A rock-shaft 22, suitably journaied in bosses 23 and 24, connected, respectively, to the air-mixer 6 and the said bridge-piece 18, has at its forward end an enlargement or head .25, through which extends and in which is secured a rod which presents the rock-arm 26, whose free end is in connection with the before-mentioned valve 12, said rod also presenting the threaded arm 27, provided with a weight 28, mounted upon the threaded portion of the arm. This weight serves to normally hold the rock-shaft in such position that the rock-arm 26 maintains the valve 12' in closed position. Extending from the rear of said rock-shaft is a rock-arm 29, adapted to play between the said connector' onln'idge-piece l8 and the said projection 21, said bridge-piece and projection serving to 0 limit the extent of movement of said rockl made and assembled. Furthermore, all danarm, and thus limiting the extent of movement of the valve 12, which is controlled by the rock-shaft upon which the rock-arms are mounted. Slidably removably seated in the bore of the socket-member 19 is a post 30, whose lower end rests upon said rock-arm 29, the upper end of said .post being preferably provided with a flattened head 31, which when the parts are in what has been termed normal positions, with the valve closed, project slightly above the upper surface of the grill 2, which in a well-understood manner supports the vessel to be heated. A guard-plate or projection 32 is mounted upon the post 30 and extends circumferentially about the same, this guard or deflector being located only a short distance above the said socket member, so that any grease or the like which may flow down the post 30 is by this guard 32 deflected from the top of the socket member 19 and is thus prevented from entering the socket in which the post is received or from collecting on the post, and thus causing said post to bind in its socket or work stifliy.

The operation of the present burner will be apparent. The valve 12 and the post 30, together with the rock-shaft 22 and the parts connected thereto, being in their normal positions, with the valve closed and the head of the post projecting above the grille 2, when the need1e-valve 4. is open to admit gas into the casing 7 the pilot-burner 17 can be lighted, but no gas will flow into the main burner 5. When the vessel to be heated is placed upon the stove, however, it of course rests upon and depresses the post 30, whereupon the shaft 22 is rocked against the force of the weight 28 and the valve 12 is thrown into position to connect the ports 10 and 11. The gas thus flows from the casing 7 into the burner 5 and is ignited by the flame from the pilot-burner 17. As soon, however, as the vessel is removed from the burner and the weight is thus taken off of the post 30 the weight 28 rocks the rock-shaft 22 back to normal position, the post 30 being raised into its projected position and the valve 12 being thrown into its normal position, cutting off communication between the casing 7 and the burner 5. Of course when the vessel is replaced upon the grille 2 the post 30 is again depressed and the shaft 22 is rocked to move the valve 12 into such position as to again open communication between the casing 7 and the burner 5. Therefore, although the pilot-burner Will remain lighted as long as the needle-valve 4 is Open, the main burner 5 will be supplied with gas only during the time at which the vessel to be heated is above the burner, the burning of gas by the heater being avoided when the vessel is removed from above the burner.

It will be readily apparent that the present structure comprises but few parts, which operate positively and can be quickly and easily ger of grease collecting upon the post 80 near the socket member 19, and thus interfering with the proper action of said post, is wholly avoided. The post 30 can be readily removed for cleaning or repair whenever desired.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
