IMPRovEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 131,086, dated September 3, 1872.

Specification describingh certain Improvements in Burners, invented by MICHAEL B. DYOTT, of the city of Philadelphia, in the State of Pennsylvania.

kThe rst part of my invention relates to the construction and arrangement in the supplypipe, immediately belowr the generator, of a core of porous metallic packing of wire or wiregauze, surrounded or lapped tightly around by muslin or other poor heat-conducting fabric, and inserted rmly in the said part of the pipe, so'V as to serve as an incombustible retarder therein, and at the same time be prevented by the lapping fabric from becoming y unduly heated by the inclosing or surrounding pipe. The second part of my invention relates to the construction of the openin gthrou gh the plug of the stop-cock in a direction oblique in relation to the supply and discharge openings in the vertical pipe below the generator and burner-head, for the purpose of more eiectuallypreventin g any leaking through the said openings when the plug is shut consequent upon the ridges which are produced around the plug and barrel by wear.

Figure l is a vertical central section`of the vapor-burner embodying my invention. Fig. 2 is a modification of the stop-cock, shown in Fig. 1.

The head A ofthe burner is a hollow retort perforated with a ring of holes, a', near its lower end. The heater B is screwed into the upper end of the hollow head A, and projects downward, as an inverted cone, to or into the upper end of a hollow mixer, (l, through which mingledvapor and air rise. The vapor passes up into the mixer C through a generator or narrow hole, d', made in the upper end of the supply-pipe D, while the atmospheric air enters C through a ring of holes, o', at a point a little above the vapor-hole d', and thus the vapor and air mingled together impinge against the surface of the heater B, and nally escape through the ring of jet-holes a', which, being ignited, heat and keep heated both the head A and heater B. The reiiector F is screwed fast upon the upper end of the burner-head A, or to that of the heater B, and is curved on its under side so as to reiiect downward and outward the light of the ignited jets, which radiate from the ring of holes a below it, the

said jets of flame in radiating from the ring of holes a curving upward toward the reflector F, as indicated by the arrows in Fig. 1. A bell-shaped guard or fender, H, is fixed around the outside of the mixer C, so as to project a little below the ring of air-holes cand thus form an annular. guard for the purpose of protecting the said holes c from sudden drafts or gusts of wind, substantially as described and shown, in the patent granted to me July 4,1871.

The core of metallic packing E consists, in the present case, of a bundle of ne wire cut in lengths to correspond with the length of the chamber of pipe D, and lapped tightly around with muslin e', so as toform a compact cylinder fitting the said pipe D. When the stop-cock G is opened the fluid from below rises and lters through the porous metallic core E, while the lapping of muslin e prevents the warmth of pipe D from being transmitted to the core, and the uid passing through the narrow hole d becomes heated, volatilized, and mingled with atmospheric air in C, and iinally escapes in dames from the jet-holes a in the headA. The lower end of the mixing-chamber or pipe O and the upper end of the core-pipe D are connected together by a Iiange on each with an isolating layer of cork, d, or other poor conductor of heat between, so as to prevent the chamber C from heating the contents in pipe I). The barrel g of the stop-cook G is cast obliquely across the supply-pipe below D, and the hole 3 through the plug g is made correspondingly oblique, so that when the cock is open the said hole 3 in the plug g aligns with the bore 4, and allows the fluid to pass freely upward through the core E; but, if the plug be now turned half around the hole 3 in the same will come into the position indi- 'cated by the dotted line c o, and effectually prevent any leaking of the iiuid through the cock. It will be readily seen that the Obliquity ofthe position of the cock G will afford ready access for operating the plug g by means of a wrench, when the cock is above reach by hand, as in street-lanterns. Fig. 2 is a modification of the cock, with a plug having an oblique hole, when the latter is applied in a barrel at right angles to the supply-pipe, the bore 4 of the supply-pipe be ing obliqued both above and below the plug so that the parts will operate together precisely as in ,the cock in Fig. 1. In Fig. 1 the plug ot' the cock is a cylindrical screw, and therefore retained in the barrel Without any collar. 1n Fig. 2 the plug is tapered, and retained in the barrel by a collar, in the usual manner. The burner-head A and the reector F are both in this instance made of iron, and coated ou the outer surfaces With nickel and then burnished, thus producing a brilliant reiiecting surface that will not be impaired by the flames. The head A and reflector F may be made of White porcelain, for the same purpose.

I claim as my invention- 1. The incombustible porous core E, lapped around With muslin or other poor conductor of heat, and inserted Within the pipe D, the saidA across the saine, as shown in Fig. 1. Y
