GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 544,422, dated August 13, 1895.

.Application tiled January 2 9, 1 8 95.

Serial No. 536,530. (No model.)

To a/ZZ whom, it may concern.-

Be it known that I, EUGENE H. YORKE, a citizen of the United States, residing at Boston, in the county of Suffolk and State ot' Massachusetts, have invented a new and use` ful Improvement in Gas-Burners, of which the following is a speciiication.

This invention relates to that class of gasburners termed automatically -lighting burners, and in which a pilot-light or ignitionjet is employed for lighting the gas issuing from the tip of the burner when such gas is turned on; and the invention consists in the novel construction and arrangement of parts hereinafter described, whereby the gas-burner is rendered more efficient, economical, and certain in operation, and the pilot-light is rendered always constant at a low point, there being no dashing or streaming up to the burner-tip, all as illustrated in the accompanying drawings, in which- Figure 1 is an elevation of my improved gas-burner. Fig. 2 is a vertical section taken on line Fig. 5. ln these two figures the ignition-jet is burning and the burner'- tip is elevated sufficiently to receive a smallstream of gas, sufcient, however, to be ignited by the pilot or ignition jet. Fig. 3 is a vertical section taken on line Fig. 5, the burner-tip being elevated but not raised to its fullest extent. Fig. 4 is a vertical section taken on line y, Fig. 5, the parts being in the position indicated in Fig. 2. Fig. 5 is a plan view with the hood removed.

Similar letters of reference indicate corresponding parts. Y

A represents a tube or pillar which corresponds to the base portion of the ordinary burner, and is screwed at a upon the gas-tixture. To the upper portion of this tubular pillar is screwed at b an annular ange B, which supports and to which is screwed the hood C, provided with suitable windows C', neither said hood nor the iiange B, which forms the base thereof, being new in this invention.

D is the tip supported by the socket D, said socket surmountin g and being supported by thehollow piston E, closed at its lower end at E and moving vertically within a stationary tube or cylinder F, screwed at f into a central opening in the base or Iiange B and preferably provided with a small annular flange F', which overlaps the edge of said central opening, and closed at its lower end at F. The hollow piston E is provided with a port e and also with a small port or perforation e', and the tube orcylinder F is provided with a long port g.

H is a lever formed at H into a ring which straddles the pillar A, and whereby it is pivoted thereto at h. The outer end of this ring has pivotally hung from it at H a bar I, whose lower end is formed into a handle or weight I', the whole acting as a counterbalance. To the opposite end ot the lever H there is pivotally connected at J a link J, which extends up through a suitable opening B in the base B and connects at J with the jawsK of a ring K clamped around the lower end of the tip D. An integral extension K from the opposite side of this ring is perforated at 7c, and a vertical guide-rod L extends up from the base B through said perforation and has screwed upon it above the extension K the stop-nut L.

The gas-pillar A is provided with a wing A', which has a passage N leading from the interior or gas-passage of the pillar to a coincident opening in the base B of the hood, into which opening is screwed the ignition-tube P, which constitutes the pilot or torch. The

screw R is for regulating the flow of gas.

through the passage N. S S are respectively openings in the hood above the tip D and pilot P.

The normal position of the device is with the pilot-light burning, the handle or weight I elevated to its highest point, the link J correspondingly depressed, the tip-socket D lowered to the base B, and the hollow piston E lowered to the bottom of the cylinder F. In this position the ports e g are non-coincident. When the burner is to be lighted, the handle l is pulled down. As soon as it reaches the point indicated in Figs. 1, 2, and 4 the,

small perforation e in the hollow piston E becomes coincident with the lower end of the long port g in the cylinder F. As the hollow piston E continues to rise-being pulled up by the tip-socket D', which is actuated by the clamping-ring K-while the perforation e is moving up the length of the port g, gas in a small stream enters the hollow piston E and IOO thence passes through and out of the tip D and is ignited by the frame from the ignitiontube l?, so that during this movement a small llame proceeds from the tip. Immediately after the perforation e has passed beyond the upper end of the port g the rising hollow piston E brings the porte into coincidence with the port g, as shown in Fig. 3, and a little further upward movement lets on a full stream of gas. The upward movement of the socket is guided by means of the rod L and extension K and is limited by the adjustable nut L. Upon reference to Fig. 3, therefore, it will be seen that the tip could be raised still higher by lifting the nut L. To shut off the gas, with the exception of that which is fed to the ignition-tube P, the operation is reversed by lifting the handle I.

It is intended that the handle I and rod I shall be of such a weight that the lever I-I I-I may be left and remain in any position. No cock is required in the base of the gas-pillar, and inasmuch as the gas in the tip is first ignited in a small and slender stream passing through the perforation e there is no flashing or streaming up of the flame.

IIaving thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a gas-burner of the character described, the combination of a cylinder set within the gas pillar and of suitable diameter to allow of a space between it and the inner wall of said pillar, said cylinder being provided with the long port g, a hollow piston adapted to move vertically in said cylinder and extend through the upper end thereof ration e comes into coincidence with the port y g in advance of the coincidence of the port e with the port g, substantially as described.

2. In a gas-burner of the character described, the combination of the gas pillar A supporting the hood C, the cylinder F supported centrally in said pillar and provided with the port g, the hollow piston E adapted to move vertically in said cylinder and provided with the port e and perforation e', the tipsocket D supported by the hollow piston, the perforated extension K extending horizontally from the tip socket, and the vertical guide rod L extending from the base of the hood and provided with the stop nut L', substantially as set forth.

3. In a gas burner of the character described, in combination, the gas pillar A supporting the hood C, the cylinder F supported centrallyin said pillar and provided with the port g, the hollow piston E adapted to move vertically in said cylinder and provided with the port e and perforation e', the tip socket D supported by the hollow piston, the clamping ring K, lever II H pivoted to the gas pillar, the link J connecting one end of said lever with the clamping ring, and the rod I and handle I depending from the other end of said lever, substantially as described.
