IMPROVEMENT lN DUTCH OVENS.

Specification forming part of Letters Patent No. 175,050., dated March 21, 1876; application iled February 2l, 1876.

To all whom it may concer-n:

Beit known that I, AGARITHE J oANNY DE- JEY, ot' Paris, in the Republic of France, have invented a newfand useful Improvement in Dutch Ovens; and I do hereby declare that the following is a full, clear, and exact description ot the same, reference being had to the accompanying drawing, which forms a part of this specification. A

My invention has for its object the auto matic turning of meats when the same are roasting in Dutch ovens, to insure their uniform cooking, and obviate the necessity of an attendant to turn the spit or frame which supports such meats, and also to provide convenient means for basting meats while roasting.

The invention consists, partly, in a turbinate wind-wheel, attached to the frame or spit which supports the meat while roasting, com bined with a portable furnace and Dutch oven, such wind-wheel being driven by ascending currents oi' heated air and gases from the roasting-tire passing through the interior of the Dutch oven. It also consists in the construction of such turbinate wind-wheel to project over the perimeter of the top of the Dutch oven, so as to be propelled, in part, by ascending currents of air, heated by radiation from the exterior of the shell of such Dutch oven. It also consists in a cup-shaped disk, attached to the central portion oi the turbinate windwheel, with openings in the bottom ot said disk, by which means the meats are basted while roastin g. It also consists in a turbinate wiud-wheel directly attached to the frame or spit which supports the meat in aDutch oven, such frame or spit being turned by the action of ascending heated gaseous currents upon the turbinate wind-wheel.

Figure 1 in the accompanyingdrawing rep resents a central 4vertical section through a Dutch oven and furnace comprising my invention. Fig. 2 is a top view, with onehalf the turbinate wind-wheel removed.

Similar letters refer to like parts in figures.

S is'the shell of the oven.

both

It has two openings, preferably, but not necessarily, placed opposite each other, one of which is, when the oven is in use, closed by the door D, the other opening being closed' by the furnace F, which quite closely tits the said opening. The bottom B of the oven is, preferably, inclined to one side, to cause the drippings of the roasting meat to run down into a hollow, H, formed near the door D. To the bottom B is attached a step, R, which supports the lower bearing b1 of a frame, f, which supports the mea-t while roasting. From side to side, at the top of the shell of the oven proper, extends a bar, L, in the middle of which is a hole or bearing, b2, for the upper pivot p2 of the frame f. The fra-me f is provided witha hook, 1L, or other suitable means for attaching the meat to the said frame. To the pivot p2 of said frame f is attached the turbinate wheel W, the vanes u of said wheel being inclined to form an angle with the direction of the ascending air-cur rents. Said wheel W is, preferably, formed with a rim, r, which serves to connefthe ascending air, and renderits action upon the wheel more efcient. The vanes o of said wheel are joined to the said rim r at their outer extremities, and at their inner extremities to a cup-shaped disk, d, with openings o at 1the bottom. The turbiuate wheel W projects over the perimeter ot' the upper part of the shell S, as shown at P, the said projecting part ot' the wheel assisting to drive the same.

may use beneath the turbinate wheel W a Vtired wheel, with directing blades-orvanes,'to

deflect and guide the ascending currents of air, and render their action uupon the said wheel lnorerefticient; but this modification is not essential to the proper working of the apparatus.

The furnace F may be variously constructed, with a fire-box for the fuel, grate for supporting said fuel, and a grating, g, in front, with a fender, m, at the bottom of said grating, to keep ashes and cinders from falling into' the oven'botto'm B through the side of the furnace placed toward the oven proper, which side is open to allow the product of combustion to pass through the said oren, and the heat from the fuel to radiate into said oven. Air-holes c, for admitting air to the re-box of the furnace, are also provided, either with or without dampers. i

The said furnace is removable from the oven proper, and both the shell of the oven proper and the shell of the furnace may be provided with suitable legs or supports, and

with handles for convenient handling.

In use, the meat is attached by the hook h, 0r otherwise, to the frame f. Fire is kindled in the removable furnace F, which is placed so as to cover the opening opposite the door D, and with its open side facing the interior of the shell S. Air then enters the air-holes a, passes through the furnace, and gives up oxygen tothe fuel, and the heated gases pass out through the oven and upward, as indicated by arrows, through the vanes of the turbinate wheel, rotating the said wheel, and with it the frame or spit with the attached meat.

Goal is represented as the fuel in the drawing; but gas or other fuel may be used.

The drippings of the roasting meat are dipped out of the hollow H in the bottom B, and are poured into the cup-shaped disk d, whence they gradually drip down through the openings o upon the meat, thus basting the same.

I claim- 1. The combination of the furnace F, the Dutch oven, the meat-supporting frame f, and the turbinate wind-Wheel W, whereby the said frame or spit is turned by the heated air and gaseous products of combustion passing from the furnace, through the oven, to said Wheel, substantially as set forth.

42. The turbinatc wind-wheel W, directly attached to the frame f, which supports the meat in the oven, substantially as herein described.

3. In combination with the turbinate windl wheel W, attached to the meat-supporting framef of a Dutch oven, substantially as de-` scribed, the central cup-shaped disk d, with 'openings o at the bottom, substantially as and for the purpose herein described.
