IMPROVED TORCH FOR LIGHTING GAS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM EDWIN HEATH, of Pembroke Terrace, Gloucester Road North, in the county of Middlsssx, Kingdom of Great Britain, have invented a new and improved Mode of Lighting Street and other Gas Lamps and do hereby declare that the following isa full and exact description thereof, referepee being bad to the accompanying drawings, and to the letters of reference marked thereon.

v The said invention consists chiefly in the construction of a lamp, with a peculiarly constructed case or covering, in which, while allowing a free entrance to the air in sufiicient quantities to support thecombustion of the said lamp, will yet prevent the flame thereof being extinguished by the wind or rain wlien the lamp is being carried through the streets. The said invention also consists partly in the means for opening and closing the cocks of the gas-burners when the same are lighted and extinguished. l

Description of the Drawings.

Figure 1 is a longitudinal section of the apparatus.

Figure 2 is atransverse section of the same on the line a: z, fig. 1.

Figure 3 shows a burner provided with the required means for operating the cock thereof.

Figure 4 is a plan of the top of the interior tube.

Like letters refer to corresponding parts in each'of the figures.

The case or cover consists of an outer and inner tube, A and B, the comparative diameters thereof being. such that when'the latter is placed inside the former an annular space is left between the two. The outer tube is extended to fit over the end of the lamp 0, to which it is secured by the catch at. These tubes are formed of tin or other suitable metal, and are provided with the holes or perforations I; through which air is admitted to the lamp. The two tubes are so arranged, with regard to eachother, that the perforations b, in the outer tube A, lie beween those in the inner tube 13, as shown in figs. 1 and 2, so that the air in entering through the apertures b, in the outer case, is checked and prevented entering directly into-the case or cover. By this means the flame of the lamp, while. freely supplied with air, is eifectually sheltered from the sheets of the wind and rain, and the apparatus can be safely carried in the open air without danger of extinguishing .the said flame.

"The outer case A is also extended above the inner tube 13, and is provided with a cap or top, D, which is secured to the former by the screw 0 or by other suitable means. The said cap is formed with the boss or projection at around the aperture e, to prevent the entrance, through the said aperture, of Water, which in wet weather might be caught and held by the said cap. The raised rim is provided to enable the burner cocks to be readilyppened and closed. The top of the inner tube'B is also provided with a cover, E, provided with the apertures f.

The lamp 0 is by preference constructed of brass, and of suitable form; and size to hold conveniently the required quantity of oil, Theineck g of this lamp is made conical or tapering, and is provided at its upper end.

with a flange or rim, 5, which, for convenience, is formed on the screw 2'. The said lamp is also provided with a wick-tube, j, wherein a wick is introduced in the ordinary manner. The lamp G is also furnishedwith the socket F, which is by preference formed of tin and soldered to the lower part of the said lamp.' 'One'end of a light pole, or rod of ash, or other suitable wood or material, is inserted into this socket, and the apparatus-is thereby conveniently carried from place to place with its lampburning.

To enable the apparatus to be efl'ectually used it is necessary that the plugs of y the burners to be lighted thereby should be' provided with the double handle it, represented in fig. 3, which may be easily applied to ordinary gas-cocks already in use, by forming a flange on the/double handle .to correspond with the handle of the said cocks, and uniting them by screws or rivets. The plugH is prevented turning more than a quarter of a revolution in either direction, either by means of the recess 7:7,,01 by providing the plug with two of the pins or stops l. When. the burner is to be lighted the apparatus is inserted through the bottom of the lamp, till its end, coming in contact with the handle, turns'it over into the position represented iii dotted linese The cock of the burner is thus opened, and the gas escaping therefrom, entering through the: apertures?) andd", comes in contact with the flame of the lamp C and is thereby lighted. To turn oh the gas the apparatus is again inserted through the opening in the bottom of the lamp till it strikes the wing in of the handle G, which is thereby turned back into the positions shown in full lines in fig. 3, and thereby closes the burner;

What I claim as my invention, and desire to secure by Letters ,Patent,"is--' L' flfhe cpnstructionof the double ease or cover having the perforated tubes A and B arranged oz'ie within the other} for the. purpose and subsfantialiy in the manner set forth. I I

2. The double handle G,'a lapted either for burners constructed as shown in fig.- 3, or for m'dinary gesburners, for the purpose and substantially in the manner set forth.

3. The apparatus censisiing of the tubes A and B, cap I), lamp 0, and so cket F, constructed and combined for the purpose and substantially'ihth'e in anner s'etforth. W. E, HEATH.
