GAS AND LIKE COOKING-OVEN'.

Specification of Letters Patent.

Patented May 23, 1911.

Application led .Tune 20, 1910. Serial No. 567,965.

.To all whom it may concern: A

Be it known that I, JOSEPH ARTHUR FORD GLovER, a subject of the King of Great Britain and Ireland, and a resident of Wandsworth, Surrey, England, have invented certain new and useful Improvements in Gas and Like Cooking-Ovens; and .I do hereby declare the following to be a full, clear, and

oven on the line, 1-1, Fig. 2; Fig. 2 is av sectional elevation on the line 2-2, Fig. 1; Fig. 3 is a sectional plan on the line 3-3, Fig. 1; Fig. 4 is a plan of Fig. 2; Fig. 5 is a front elevation; and Fig. 6 is a sectional elevation on the line, 6-6, Fig. 1.

The apparatus comprises an oven proper, a, having a door, al, and supported on legs or walls, as, arranged so as to form or leave a receptacle orspace, a", for lreceiving a gas or oil stove, -such as a, for example, shown in dotted lines.

According to the invention, the'oven bottom, a5, is formed with an opening, a?, for the fiames or heated gases direct from the lamp or burner, placed thereunder, to pass through. An inverted detlecting cone, b, is supported a short distance above the opening to evenly distribute the heat to all four sides of the oven, the flames or heated gases impinging on the inclined sides of the cone. rlhe opening, a6), also serves for the entrance of air which becomes-heated by the flames and the hot cone in passing through the annular inlet formed between the edge of the opening, a6, and the wall of the cone. The cone is supported preferably by legs'or distance pieces, b1, a short distance below a false bottom, b2, so as to leave an insulating air space between the cone and the false bottom. The false bottom is preferably removable, to permit of its being readily taken 'out and renewed, and has legs, b3, shown as perforated plates, resting on the oven bottom, a5. v

b4 is a shield arranged between the cone and the false bottom, to leave a secondary air space beneath the false bottom and to aid in equalizing the temperature of the latter. proper to the oven for dishes or other articles to rest on. rllhe dist-ance pieces b1, are attached at their tops to the shield b4 by rivets which also serve to attach shield b4 to the false bottom b2. The false bottom is of such dimensions as to leave a space, m, all around between its four sides and the four walls of the oven, to enable the heated gases to rise at the four sides. The false bottom is kept central by suitable means, for example, by bars, b5, and projections, be.

c represents ledges for supporting a tray, d, for heating or cooking things in the upper part of the oven. The ledges and trays are arranged so as to leave a space, y, at the four sides, to enable the heated gases to rise. i

At, a short distance from the top of the oven is provideda reflecting plate, e, for re'- flecting the rising heat toward the central part o the oven. The plate, e, also serves as a support for kettles, saucepans, or the like, placed through openings, a9, in the oven- The false bottom serves as a bottom top. The plate is perforated, as at el, and

is formed with depending corrugations, as at e2, to enable the heated gases to freely circulate under the bottom of the saucepans or the like. The heated gases can also circulate around the bottom parts of the saucepans or the like. The plate, e, is of such dimensions as to enable the heated gases to` front plate, al", and is secured in position by a notch, f1, engaging the front plate.

The various arrows in the drawlngs illustrate diagrammaticallyl how lthe heated gases circulate within the oven and secondary chamber.

'The invention is of advantage in that the articles being cooked` or heated are on all sides subjected to the heat lfrom the uprising heated gases, and the heat being reflected at the' upper part of the oven the tempera-A ture is practically even at all parts thereof. Further, sincethe iames and heated gases are deflected immediately they impinge heate against the inclined sidesd of the cone, the latter lasts longer than ovens having fiat bottoms against which the flames of va lamp or burner impinge. jThe invention -is also of advantagel inv that the corrugations in `conjunction with the Aperforations in the ployed than customary, whereby a saving in fuel is obtained.

What I claim as my invention and desire to secure by Letters Patent is f An lovenl for cooking or heating articles, constructed with an openin adapted to' receive heated air and products of combustion and an opening in the top, and having a short distance above the bottom opening a suitably supported inverted deflecting cone, and a short distance below the top opening a suitably supported late provided with corrugations and per orations, the plate being adapted to serve the twofold purpose of reflecting the rising heat toward the central part o the oven and of supporting a 'receptacle Iwhen placed throughthe top opening, substantially as described. 'e

In testimony whereof I ax iny signature, in presence of two subscriblng witnesses.
