2 Claims;

This invention relates to a combination deep well and top cooking unit for a cook stove, and has for its primary object to increase the utility of the cooking unit.

With the ordinary type of cook stove equipped with a deep well, the heating burner for the well is fixed in the bottom thereof, with the result that the deep well which is used only infrequently occupies space in the top of the cook stove which could normally be employed for top-of-stove cooking, but inasmuch as the burner is'fixed in the bottom of the deep well, the space occupied by the deep well is sacrificed for a unit that is only infrequently used.

The prirnary'object of this invention is to providethe advantages of deep well cooking and at the same time avoid the sacrifice of the space required therefor in a stove top.

Another object is to enable the deep well burner to be used for top-of-stove cooking, without sac rificing the deep well and the advantages to be gained through the use thereof.

The above and other objects may be attained by employing this invention, which embodies, among its features, a tubular jacket entering the cooking top of a conventional cook stove and depending therefrom, a burner mounted in the jacket to move longitudinally therein from a deep well cooking position to a top cooking position andTflexible means entering the jacket through its bottom to supply the burner with heating energy.

Other features include means releasably to support the burner in its top cooking position, fiues coupled to the jacket intermediate its ends for conducting air and gases in the jacket to atmosphere, and vessel-supporting fingers on the top of the movable burner for holding a vessel in spaced relation to the top of the burner to provide a space in which combustion may take place;

Referring to the drawings in detail, a stove dese ignated generally ll! equipped with a cookies top ll having, at spaced intervals therein, burne'rs l2 of conventional form constituting the top cookingburners of the stove; Formed the cooking top H is an opening i3 through which a tubular jacket l4 extendsihtotheinterior of the stove, as will be readily understood uponreference to Figure 1. The jacket 14 is provided at its upper end with an outstanding annularflange i5forining a stop which engages the stovetop II, and the lower end of the jacket 54 closed by a bottom l6 havingformed therein an annular row of vents l'l' throughwhich air admitted into the jacket. Formedin the bottom it to one side ofthe longitudinal axis of the tubular jacket I4 is a passage IS, the purpose of which will be more fully hereinafter explained. Fb fmed in the side wall of the jacket l4 ata point intermed ate its upper and lowerends is a horizontalrow oi spaced, internally screw-threaded openings it, into which are fitted the ends of fine pipes 28. The ends of the flue pipes 20 opposite those cornmunicating with the interior of the jacket iii open into a conventional flue 2| formed at" the back of the stove which communicates with at-imosphere. a

The stove above referred to is-equipped with aeonventi-onal pilot burner 22 from which tubes 23 radiate to the various burners [2 so that-when gaseous fuel is admitted to-the burners l2; they will automatically light in a oQnVen f ionalmanner.

Formed in the jacket 14 nearits upper end is an opening 24-and a similar opening 251s iorn ed near the lower end of. the jacket; An ignition tubeZE is threaded into the opening'Hand-leads to" the pilot burner 22, and threaded into'the opening 25 is a coupling unit 21 to whichan ignition tube 23 is coupled. The end of the ignition tube 28 opposite that which is connected to the coupling 2'! is connected to the pilot burner 22, and it will thus be seen thatthe pilot the flue 2! to atmosphere.

3 burner will be effective to light a burner in the top or the bottom of the jacket l4.

Mounted for vertical Sliding movement in the jacket I4 is a gaseous fuel burner 29 to which one end of a flexible tube 30 is coupled. This tube 3|] extends through the opening [8 as illustrated in the drawings and the end opposite that which is coupled to the burner 29 i coupled through a control valve 3| to the fuel distributing pipe 32 of the stove. It will thus be seen that when the valve 3| is opened, the gaseous fuel will be conducted through the flexible pipe 30 to the burner 29 and flowing through either the pipe 26 or the pipe 28 to the pilot burner 22, it will become ignited, thus igniting the gaseous fuel emitted through the ports of the burner 29 and causing it to burn in the conventional manner.

In order to provide space for the combustion of the gas flowing through the burner, the burner is provided on its upper side with an annular row of upwardly and inwardly extending vesselsupporting fingers 33 upon'which the bottom of a vessel V rests;

As illustrated in Figure '5, the jacket i4 is formed at radially spaced intervals with longitudinal grooves 34, and formed at radially spaced top cooking on the top of the range.

points on the burner 29 are radially extending said grooves are horizontal grooves 36 which,

when the burner is in elevated position, receive the lugs 35 and serve to sustain it against downward movement; It will thus be seen that by lifting the burner 29 manually and then partially turning it whenitreachestheupper-end of the jacket M, the lugs 35 will be moved into the grooves 36 to sustain the burner in elevated position. When in such elevated position, the burner serves admirably as a top cooking unit to augment the burners [2 of the'stove; 1

In its preferred formgthe vessel V is equipped with a cover C which is adapted to be sealed in place in order that the juices and volatile matter contained in the'food being cooked in the vessel cannot escape. In order to avoid wear on the tube during its movements into and out of the jacket I4, I attach to the lower end of the jacket adjacent the opening l8 a bracket 31 in which is mounted a guide roller 38 against which thetube 30 runs during the raising or lowering of the burner 29.

In use, the burner maybe lowered as illustrated in Figure 1 into the jacket I4 and upon opening the valve 3|, the gaseous fuel will flow from the pipe 32 through the flexible tube 30 to the burner, thus supplying it with fuel. Air to support combustion or the gas issuing from the burner is introduced through the tube 30 in the conventional manner and also enters the jacket 14 through the openings [1. By reason of the fingers 33, the vessel V entering the upper open end of the jacket [4 will be held in spaced relation to the burner, thus providing combustion space within the jacket, and the products of combustion rising through the jacket may escape through the flues 2D to be discharged through The gas flowing to the burner 29 will pass upwardly through the tube 30 to the pilot light within the igniter 22, to convey the flame downwardly to the burner and causethe gas issuing therefrom to become ignited. V i a When the burner is to be used as a top burner unit, it is elevated by entering a hooked rod into the upper end of the jacket I4 and engaging one of the flngers 33 to enable the burner to be lifted by pulling the rod upwardly. When the burner has been moved to its uppermost position within the jacket [4, the burner is given a partial turn so as to cause the lugs 35 to move from the grooves 34 into the horizontal grooves 36 and thus the burner will be sustained in elevated position to serve as a top cooking unit. Ignition of the burner is established automatically through the gas flowing therefrom through the pipe 26 to the pilot 22 in a conventional manner.

By the use of this device, it is obvious that the space normally occupied by a deep well cooker in the ordinary range may be utilized not only for the purpose of deep well cooking, but also by elevating the burner the burner may be used for Thus, its service may be greatly increased and the advantages of having top burners in all burner openings of the range may be readily ,realized'without sacrificing the advantages of-- deep well cooking.

While in the foregoing there has been shown and described'the preferred embodiment of this invention, it is to be. understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:
