SELF-LIGHTING ATTACHMENT FOR GAS-BURNERS.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed June 26,1906. Serial No. 323,477.

To all whmn it ntay concern.-

Be it known that I, FRANCOIS CI-IIPAULT, a citizen of France, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Self-Lighting Attachments for Gas- Burners, of which the following is a specification, reference being had to the drawings accompanying and forming part of the same.

My invention relates to self-lighting attachments for gas-burners, and has for its chief object to provide an effective and durable device of the character which shall be simple in construction and readily applicable to existing burners with but slight if any modification of the latter.

To this and other ends the invention consists in the novel features of construction, arrangements of parts, and combinations of elements hereinafter described, and more particularly set forth in the appended claims.

In the annexed drawings I have illustrated the preferred form of my invention, wherem Figure 1 is a side elevation, partly in section, of an incandescent gas-burner with my attachment applied to it' Fig. 2 is a detail side view at right angles to that of Fig. 1, showing the valve-actuating device. Fig. 3 is a detail sectional view of the device for igniting the pilot-light. Fig. 4 is a detail sectional view of the pilot-valve and connec tions. Figs. 5, 6, 7, and 8 are sectional views on line V V of Fig. 4, showing the four different positions of the pilotvalve.

Referring now more particularly to Fig. 1, A indicates an incandescent gas-burner of any convenient type, having a Bunsen or mixing tube a leading to a burner-cap a, over which is suspended the mantle. (Not shown.) The lower end a of the mixing-tube is internally threaded, as is customarily done for the purpose of attachment to the threaded end of a pipe or fixture conveying gas. In the present case, however, the burner is screwed on the threaded nipple b of a valve member B, Figs. 1 and 4.' The latter is preferably of cylindrical form and has in its lower portion an upwardly-tapering or conical opening or socket b for a correspondingly-tapered plug or seat B. The latter is hollow, as shown in Fig. 4, and is internally threaded at its orifice so as to be screwed on the gas-fixture.

The member B is provided with a gas-passage b extending from the side of the socket I) to the longitudinal passage in the nipple b, and in the side of the tapered seat B in the same horizontal plane as the inlet of the pas sage b is an aperture 6 It will therefore be seen that by turning the cylindrical valve member B the passage b therein can be thrown into or out of register with the aperture [2 thereby opening or closing the supply of gas to the burner.

Through the side of the valve member B opposite to the passage 6 but somewhat less than one hundred and eighty degrees therefrom, is an aperture 1), adapted to receive the threaded neck 0 of a support C for a pilottube. For convenience of illustration the aperture b in Fig. 4 is shown diametrically opposite to the passage 6 The support C has an opening in its upper side to receive the lower end of the pilot-tube and its neck 0 is provided with a longitudinal passage 5 in communication with the aperture in which the neck is secured. Diametrically opposite the main burner-port b in the conical seating member B is a pilot-port 1), adapted to register with the adjacent orifice of the aperture 6 when the valve member B is rotated to the proper extent. The parts B and B may be conveniently secured together by a screw 8, extending through the top of the seat B, as shown clearly in Fig. 4.

The position of the parts when the burner is not in use is shown in Fig. 5. Therein it will be seen that the valve member B occupies a position in which neither the passage 1) nor the aperture b is in register with the adjacent port in the conical seat. If new the outer member B be turned in the direction of the arrow in Fig. 5 to the position shown in Fig. 6, the aperture l) willbe brought into register with the pilot-port b and gas will flow into the pilot-support and thence to the pilotburner, hereinafter described, while the passage b will be carried beyond the main burnerport b If now the rotary valve member be turned backward, or counter-clockwise, to the position of Fig. 7, the passage b will be brought into partial register with the main burner-port b and gas will flow to the mixing-tube, while the pilot-aperture b will be in partial register with the pilot-port. The means whereby these movements effect the ignition of the burner will now be described.

The pilot-tube P extends into the support C and preferably fits loosely enough therein to be readily withdrawn when desirable for any purpose, as cleaning, or repair, &c. The tube extends through the bottom of the chimney-gallery G, Fig. 1, and is provided with a flat rectangular block R, provided with a longitudinal passage 1", communicating with a transverse passage r and a second longitudinal passage 7, communicating with the latter. Above the block, which preferably rests on the bottom of the chimneygallery, the pilot-tube extends from the passage into proximity to the mantle, so that the pilot-flame will ignite the gas issuing from the main burner. On the top of the block R, in communication with the passage 1- and alongside of the pilot-tube, is a small auxiliary pilot-burner p, and extending above the latter, supported on standards 19 p, are buttons of catalytic material 12 arranged so that gas issuing from the auxiliary pilotburner will strike them and be ignited. Depending from the catalytic bodies are the usual platinum wires 19'.

It will now be seen that when the valve is turned to the position of Fig. 6 the gas pass ing through the pilot-port b and into the lower end of the pilot-tube will flow into block R, and issuing in a fine stream against the igniters 19 will be ignited thereby, the flame extending from the auxiliary pilot to a point adjacent to the upper end of the pilottube. At the same time gas flows from the block into the upper part of the pilot-tube and issuing from the end thereof is ignited by the auxiliary flame from the small burner 19. The valve B is now turned to the position of Fig. 7, whereupon gas is admitted to the mixing-tube a and is ignited at the burner by the pilot-flame. As soon as the main burner is lighted the member B is turned to the position of Fig. 8, in which the supply of gas to the pilot-burners is cut off and the catalytic bodies 19 are no longer subjected to the injurious eflect of the flame from the auxiliary pilot-burner.

For the purposes of turning the valve member B (and of course with it the main burner and other parts which the said member carries) to the various positions described, devices are provided as shown in Figs. 1 and 2. Pivoted at its center to the lower part of the member B is a lever D, to the ends of which are secured operating-chains d d. Extending upwardly from the lever at its pivot is an arm provided at its end with a longitudinal slot (1 Rigidly secured to the valve member B is a finger (1*, which extends through the slot d It will be seen that-if the chain (1 is pulled downward thewalvemember B will be rotated in the direction of the arrow in 5, while if chain d is pulled the valve member will be rotated in the opposite direction. Preferably the arrangement and proportions of the parts are such that pulling the chain cl down as far as it will gothat is, until the upper end of slot 61 strikes the finger d will bring the valve member B to the position of Fig. 6, and pulling chain at down until the upper end of the slot strikes the pin will restore the parts to the position-of Fig. 5, while with the lever at an angle of about forty-five degrees to the horizontal the parts will be in the position of Fig. 7 and with the lever horizontal, as in Fig. 1, the parts will be in the position of Fig. 8, in which only the main or illuminating burner is supplied with gas.

From the foregoing the manner in which the device is used will be readily understood. The parts being normally in the position of Fig. 5, with the left end of lever D depressed, whenit is desired to light the burner the chain d is pulled down as far as it will go, bringing the parts to the position of Fig. 6. The pilots are now ignited, whereu on the chain (1 is drawn down until the ever D makes an angle-of about forty-five degrees to the horizontal, thus bringing the parts to the position of Fig. 7, delivering gas both to the mantle-burner and the pilot-burners. The gas issuing from the mantle-burner is ignited by the main pilot-flame, which is then extinguished, as already described, by drawing the lever to the horizontal position, which also brings the apertures b and 6 into complete register. v

The lighting attachment can readily be applied to any burner by removing the latter from the fixture, screwing the attachment on the fixture, and then screwingthe burner on the attachment. With an incandescent burner the pilot-tube is passed through a suitable aperture or a ertures in the chimney-gallery and seate in its support. The

ilottube is of course made of sufficient ength to reach the main burner effectively. In practice the tube may be made long enough to reach the tallest burner, and then shortened when the attachment is to be applied to a shorter burner. From the above explanation it will be seen that my invention provides a lighting at tachment which can be readily applied to practically any type of burner without modification thereof. tachment is simple and not liable to get out of order and can be manufactured at comparatively small cost. The pilot-flame does not burn continuously, but is ignited only when the main burner is to be lighted, and is extinguished immediately afterward, thereby avoiding waste of gas and eliminating danger of fire.

It is to be understood, of course, that the form herein illustrated and described in detail is merely the preferred form and may be IIO At the same time the atmodified in various ways without departure from the proper scope of the invention, as defined by the-appended claims.
