Specification forming part of Letters Patent No. 136,104, dated February 18, 1873.

fing when a combustible oil or liquid is em- ,ployed as the agent; and the invention consists in animproved lamp, consisting of a wick, a central air-tube or tubes, and an outer casv.ing or jacket for supplying air to lboth sides'of the flame, and a vessel provided with a central flue and alcover supported by the burner, the whole being so arranged that a cookingutensil may be` applied to the top thereof.

Figure 1 of the accompanying drawingis an elevation of lighting, heating, and cooking apparatus constructed according to our invention. Fig. 2 is a vertical section of Fig. l; Fig.

3, elevation of a vessel for frying, detached; Fig. 4, elevation of boiling or decoction vessel, detached. Fig. 5 is a view of lid of latter; Fig. 6, view of stewing-vessel.

A is the case or body ofthe burner or lamp. Itis formed of a number of annular concentric chambers. The outermost chamber, B, contains oil to be supplied to the burner or lamp. Within this chamber is a tubular or annular space, C, receiving air, and forming an airjacket. oc c are ail: 1- holes communicating therewith. D is the wick-case-that is to say, an annular chamber containing a wick. Oil

' is supplied to the wick through a short pipe,

E, which traverses the air-jacket C, and opens at one end into thewick-case D, and at the other -end into the oil-chamber B. G G are concentric air-tubes, bell-mouthed at top, and

placed centrally of the lamp in air-space surrounded by the wick-case D.- The tubes are maintained by stays t.V Air is supplied by the air-jacket C and to the tubes G from an airchamber, H, formed at thebottom of the lamp within its case or shell A, and receiving air through orifices h h h. `The air-,jacket C is interposed between the oil-chamber B and the wick-case D, so vthat the oil contained in the vessel B is prevented from being overheated, andthe oil is preserved from immature evaporation. i Thus, by means of the air-conduits C G, there is a supply of air on both sides of the wick-case. I is a feed-hole for supplying the chamber B with oil. J is a screw cap or nut, which closes the feed-hole. j* is an airhole through the plug of the screw-cap J, communicatin g with the chamber B. v isd the key for raising and depressing the Wick by rack vand pinion, as usual. y is a flange xed to the lamp to shield the portion B fromthe radiation of heat. L is a chamber or vessel which is placed over the lamp when the burner is to be applied for heating and cooking purposes. This chamber L may be of any convenient eX- ternal shape and configuration. In the example shown in Figs. l and 2 the external shape resembles that of a coffee-pot, the vessel being intended for boiling, or for decoction or maceration. l is a metal flue or passage, open at both ends, and formed o r fixed within the vessel L, being attached to or in a piece with :the bottom thereof, an opening being made in the center of the bottom of the vessel L corresponding in shape and size with the; bottom end of the passage l, so that the ilame and heat therefrom may pass up through the passage l.

vessel L-that is to say, in the space surrounding the passage Z. m is a handle, and lna spout to the vessel L. ois a lid having a central orifice, o", Fig. 5. This lid, when placed on the vessel, covers the holding caf pacity of the same, but leaves space for the upper end of the passage l, so that the vheat may reach any vessel placed on the vessel L. P is another vessel of any convenient shape. The one shown is for stewing, which may be placed over the vessel L. It is attached to a flanged annular or hollow foot or stand, p, with which, it is connected by attachments px p", which rest on the lip orfilange ofthe stand p, which rests on the lid o. -There is apassage for air and heat between the vessel l? andthe foot p".

' The pan Q, Fig. 3, may be placed over the vessel L, instead of the vessel l), if it be desired to fry. The pan Q-is connected by attachments q* with a conical foot, q, on the vessel L, similar to the arrangements pp". B is an inverted cone placed within and xed to the hollow foot 1. r is an annular conical The matters tobe heated or cooked, liquid, solid, or both, are placed in the plate, forming a guard or detlector, fixed t0 the foot p* on the inside to prevent down drafts from reaching the llame. It surrounds the ue l.

Having thus fully set forth the nature of our invention, and in what manner the same maybe performed, We declare that We c1ain1-.V

The improved lamp for lighting or cooking,

consisting of the wick-tube D, central air-tube or tubes G, and outer' jacket G, by which air is supplied to both sides of the flame through scribed.

openings h in the base of the lamp, and ,the vessel L with its central ue land cover o' o supported by the burner, all constructed and arranged so that a cooking-utensil maybe applied to the top thereof', substantially as de- A. M. SILBER, F. WHITE. Witnesses:
