SPECIFICATION forming part of Iletters Patent No. 672,817, dated April 23, 1901. Application fusa January 5, 1901. serai No. 42,193. (No model.)

To a/ZZ whom it may con/cern:

Be it known that we, ARTHUR HENRY BEN- NETT, residing at 44 Swan street, Richmond, and STEPHEN JONES, residing at 51 Athol street, Moonee Ponds, in the Colony of Victoria, subjects of the Queen of Great Britain, have invented a new and useful Improvement in Gas-Burners, of which the following is a specification.

Our invention relates to a gas-burner in which a pilot-light is used for lighting the main burner, said pilotlight being extinguished as soon as said main burner is lighted and again lightedwhen the main burner is eX- tinguished.

We will now describe the invention, having reference to the accompanying sheet of drawings, in which- Figure 1 shows a view of a small example of our system of lighting, in which is illustrated a chandelier and a wall-bracket. Fig. 2 shows a vertical section of the means for controlling the gas-supply to the pilot-light and the burner. Fig. 3 shows an elevation of the construction shown in Fig. 2, drawn to a smaller scale, the sanne being here applied to an ordinary gas fitting and burner.

` t ofFig.2.

Fig. 4 shows an edge view of a portion of the parts shown in Fig. 2. Fig. 5 shows a plan of the ball-valve 11 shown on Fig. 2. Fig. 6 shows a section taken on the line A A of Fig. 2. Fig. 7 shows a section taken on the line B B Fig. 8 illustrates the operating-tap and its adjustable by-pass.

In the drawings, 1, Fig. l1, represents the ordinary gas-supply pipe, and 2 a cock on same. This cock (see Fig. 8) has a by-pass pipe 3, one end of which enters-the bore of the cock and the other end enters a` cylindrical box 4, the said box being screwed into the bore of the cock on the side of the valve opposite to that which receives the by-passpipe end. The box 4 has a smallindependenttap preferably constructed, as shown, in the form of an adjustable screw 5, which is arranged to control the passage of the bypass 3 and which will normally be kept'open or partly open, so as to allow of a constant passage of gas independently of the cock 2, so as to supply at all times the pilot-lights, as hereinafter described. The gas-supply to the burner or burners is controlled by the cock 2. Fig. 1 illustrates two incandescentmantle burners supported by a chandelier 6 and an ordinary burner on a wall-bracket fitting 7. We employ the following construction to be connected to the gas-fitting in every case: A cylinder 8 (see Fig. 2) is internally threaded at its base 9, so as to screw onto the gas-fitting. This cylinder has a milled rim 19, and the portion above same is screwthreaded. The top of this cylinder is beveled at l0, and so forms a seat for au aluminium ball-valve 1l. Said ball-valve has a rod 12 attached, and a perforated and open plate 13 is set within the cylinder and forms a guide for the said rod 12 and allows also of a passage of gas. A shouldered tube 1-4 screws onto the top of the cylinder 8 and rests on washer 20, and the shoulder 15 of the tube 14 forms a stop for the said valve. The top of. the ball 11 is cut away or grooved out at 33, Fig. 5, so as to allow of the upward passage of gas when the said ball comes against the shoulder 15. The ball will, however, in practice iioat in the tube by reason of the gaspressure when the gas-supply cock is turned on. The neck 16 of the shouldered tube is threaded both internally and externally, so that when the apparatus is employed in conjunction with a Welsbach gas-burner such burner will screw onto the external thread; but when employed in conjunction. with an ordinary gas-burner such burner will be received by the internal thread, as shown in Fig. 3. The cylinder 8 is provided at its base with a disk of wire-gauze 18 for the dual purpose of checking any foreign matters or dust and preventing back-lighting. This cylinder has a perforation through its wall, and a short branch pipe 2l screws into same. This pipe is preferably set at right angles to the cylinder. The top of this branch pipe near its end has a short pipe-section 22 screwed into it, and the bore of which latter is at right angles to and communicates with the bore of branch pipe 21, and the top of the pipe-section forms a seat for an aluminium valve 28. This valve has its top tapered conically. The wall of this short pipe-section 22 has a perforation 24 through it, and a pipe or tube 25 screws onto the said pipe-section. The perforation in the wall of the pipe-section 22 communicates with a perforation 26 in the pipe or tube 25 near its base, and which latter communicates with a by-passage 27,V

formed by a casing 28 on the tube 25, and

`which has an opening 29 into the said pipe -same being designed to control the opening 24, so as to regulate the amount of flow of gas to supply the pilot-light.

34 represents the pilot tube, which is screwed into top of the pipe 25. We provide an adjusting-screw 32, which screws into the bottom of the branch pipe 2l and has a tapered point which is arranged to regulate the amount of opening of the pipe-section 22, the object of this screw being to control the gaspressure entering the said pipe-section.

37, Fig. 3, represents an` ordinary gas-fitting in which the cylinder 8 is mounted, and17 a burner on the tube 14. When the apparatus .is employed in conjunction with an ordinary gas-burner, the pilot-tube may be bent to meet the burner, as indicated in Fig. 3; but when the apparatus is employed in conjunction with an incandescent-mantle burner the end of tube 34 will be received by a tube 35, which latter enters or is attached to the burner, as indicated at 36, Fig. 1, or otherwise.

The valves are constructed of aluminium,

' same being a light and serviceable metal; but

other suitable metal or material may be substituted therefor, provided that the loatability of the valves is preserved.

The modus'opemndt' of our invention is as follows: Assuming the cock 2 on the supplypipe 1 to be turned on and the adjusting' screw 5 set to regulate the required flow of gas to supply the pilot-light independently of the cock 2, the gas will pass by the main pipe and it-s branches to the gas-iittings and through same to the cylinder. 8, mounted thereon, and its pressure will cause the aluminium ball-valve l1 (see Fig. 2) to rise from` its seat l0 and allowr the full supply of gasy to pass to the gas-burner above. The gaspressure will cause the valve to ioat in the chamber; but should it rise to the shoulder 15 the incisions or grooves 33 in the ball will flat bottom seat and close up against the conical seat formed inside the top of the pipe or tube 25, in which it is set, so closing up' the gas-passage to the pilot-light tube 34. Ou turning oi the supply-cock 2 the valves 11 and 23 will both fall onto their bottom seats, and the gas which escapes by the by-` pass 3, `Fig. 8, and passes along the supplypipe being at very low pressure will not have suiiicient force to raise the valves, and this low-*pressure gas will pass from cylinder 8 through the branch pipe 21 to the regulated mouth of and through the pipe-section 22 and through the regulated hole 24 in the wall of same to the by-passage 27, thence through the opening 29 into the pipe or tube 25above the valve, (which latter, as before described, will be resting upon the top of the pipe-section,) and thence to the pilot-tube 34. This action will take place sufficiently quickly to cause the pilot to light before the main light becomes quite extinguished. The actions above described will be repeated on each turning on and off of the main cock, and it will be understood that the pilot-lightwill always be kept going while the main light or lights is or are out.

Referring to the pipe 34, we would have it understood that such duct may be modified or altered' in its construction or dimensions With regard to the aluminium being used as the material vfrom which to construct the valves 11 and. 23 we would say that we have found such metal to be suitable on account of its lightness and peculiar metallic properties; but we reserve to ourselves the right of constructing such valves of any other suitable metal or material either in a hollow or solid form.l

It will be understood from the foregoing eX- planations that a large number of the gasburners fitted with our parts hereinbefore referred to can be distributed over a large hall or building, and after being once lighted the whole of such burners can be turned on or off by one movement of the hand operating a cock, as 2, at any convenient center or` room or alternatively at the gas-meter, the portions of the pipe 3 and the adjustment of the screwcock 5 being previously suitably set in accordance with the number of burners-in the system.

It may be noted that where the ordinary gas-taps 38 are used any individual light may be shut off if not required. In somewhatsimilar manner to that above described our system and apparatusmay be applied to the lighting of street-lamps. In this case the attendant need simply turn on the one cock at night, and vice Versa in the morning, thus obviating the present extravagant system, wherein each individual burner must be operated by an employee either before or after the exact proper time for lighting such gas. The use of our invention thus economizes the IOO IIO

gas consumed before the proper minute for lighting at night and the gas consumed after the proper minute when the light should be extinguished in the morning.
