Patented Nov. 26, i929 ljltt CHARLES LINHARDT, JR., OF BALTIMORE, MARYLAND MARINE Application filed August il,

This invention relates to certain new and useful improvements in marine torches and has for its particular object the provision of a torch. equipped with a single tube and l? burner, each communicating with a carbide gas `chamber and a phosphide gas chamber, which structure provides a self-igniting water light and one which is instantaneous in its operation.

The present invention is an improvement over the structure illustrated in the Charles iinhardt, Jr. Patent, No. lfilQ, issued February 13, 1923.

A further object of the invention is the l provision of a marine torch equipped with a gas making chamber and a flame igniting chamber, a water conveying tube communieating with the gas and flame chambers, a

burner tube communicating with said chamber said construction when the device is in operation providing a Siphon means whereby created gas will force sufficient water through the water tube to the flame chamber to ignite the burner tube or gases passing therethrough.

A `still further object of the invention is the provision of a marine torch, simple in construction, positive in operation, and one which can be manufactured at a comparative- 39 ly small cost.

W ith these and other objects in view, the invention consists in certain novel features, combination and arrangement of parts as will be hereinafter more fully described, pointed out in the accompanying drawing, and claimed.

ln the drawing,

Figure 1 is a vertical longitudinal sectional view through the complete torch;

Figure 2 is a transverse sectional view taken on the line 2-2 of Figure l;

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure 1; and,

Figure l is a fragmentary side elevation, showing the complete apparatus, comprising the torch and the life buoy with the connecting line, all supported from the rail of a ship.

teferring to the drawing, the numeral 5 indicates the ralof a ship to which a life LFI TORCH leer. serial No. 210,477;

buoy 6 is attached in any convenient way as by the means of hooks 7 or thelike.

Attached to the life buoy 6 is a line 8, the free end of which is secured to a handle member 9 of the casing 10 of the torch. This 55 casing is preferably formed of a cylindricr` shell 1G having a bottom portion 11 and a top portion 12, all soldered or welded together to form a water tight receptacle, as clearly illustrated in Figure 1. To maintain the buoy in an .upright position I provide he bottom portion 11 with an annular weight member 13 and locate the same centrally thereof so as to assure a vertical position of the casing when in the water.

Mounted centrally7 in the casing 10 is a water conveying tube lil, its lower end eX- tending through the weight 13 and projecting slightly beyond the outer surface of the bottom 11, as at 15, said tube provided adjacent the bottom 11 with openings 1G com municating with the interior of the casing 1l), the purpose of which will be hereinafter more fully described. The opening of the tube la is normally closed 'by a valve rod 75 17, 4which extends throughout the entire length of said tube and has its upper end secured to a cap 1S, which cap is normally air and water tight on the top portion 12 of the casing, but may be readily torn therefrom by the means of a handle 19, which is secured to the cap and when the latter is torn from the head 12 it automatically lifts the valve rod 17 from the tube 14.

Surrounding the tube lll is an annular screen member 20, which has its lower end secured as at 21 to the weight member 13, while its upper end is secured, as at 22, `to the botten wall 2? of an auxiliary chamber 24:, which chamber is secured, as at 25, to the 9o interior of the head portion 12.

This chaniber 24 is supplied with calcium phosphide and is the means for igniting and rc-igxiiting the torch, as will be hereinafter more fully described. A baille 2G is secured to 95 the screen 20 near its central portion and is located within the casing 10, and this baffle is stifi'ened by means of a peripheral flange 27 am is perforated as at 28, to permit the passage of generated acetylene gas therethrough.

y its lower end projecting beyond the same Yand located within the screen 20. The upper end of this tube extends through an opening 31 in the head 12 and this burner tube is sealedby a valve rodv 32, which has its upper end secured as at'33, to the cap 18, and it is obvious when the cap is removed the valve rod 32 is dis placed from the burner tube, as previously described for the Water tube 14. Y The opening 31 in the head 12 is of a diameter larger than the diameter of the burner tube 30 so that gases from the chamber 24 will immediately escape from this chamber, become ignited and form a flame sullcient to ignite the carbide gases passing up through the burner tube 30. i

The operation of the device is approximate ly as follows: Y

The life buoy and torch is normally suspended at the rear of the ship and the torch being hermetically sealed, as illustrated in Figure 1, is ready for use, assuming there is a use for the torch, the cap 18 is torn from they head 12. rlhis-will cause the valve rods 17 and 32 to be withdrawn longitudinally from the water tube 14 and burnertube 30, and these rods are pulled entirely clear of the torch.

When this is done, the life buoy is removed from the hooks 7 and the buoy and torch are thrown together overboard.

After the torch strikes the water,y it will the generated acetylene gas, which is escaping through tube 30, and the torch will burn automatically as long as normal conditions prevail and the supply of combustible gas is continued.

The action of this torch in operation is identical with the structure claimed in my Patent, No. 1,445,222, with the following ex ceptions: The flaming gas created by water contacting with the phosphide gas is approximately simultaneous with the created carbide gas escaping from the burner tube 30.

Vthile I have described one embodiment of the invention7 it is to Vbe understood, that various changes might be made in the construction, combination and arrangement of parts, without departing from-the spirit of the invention as claimed. Y

Having thus described my invention, what Y a weight in one end, said casing forming a carbide chamber, a gas chamber interiorly arranged at the top of said casing, a water conveying tube extending longitudinally through saidv casing and gas chamber, one end terminating in said chamber and its other end extending through and securedY to the bottom of said casing, a burner tube extending through the top ofthe casing andbottom wallof said gas chamber,.said water tube-*provided adjacent its lower' end with an opening communicating with the carbide gas chamber, valves closing said tubes,'means for simultaneously removing said valves to permit water to enter the carbide chamber and also permit water and generated gas to travel to the'gas chamber to ignite the burner tube. l

In testimony whereof he hereunto aiixes his signature. i f
