Specification of Letteral Patent.

' `Patented April 6, 1909.

Application filed August 21, 1908. Serial No. 449,657.

' appertains to make and use the saine.

My invention relates to improvements in tireless cookers, and its object is to provide convenient vessels for the articles to be cooked; to provide a lining that can be readily removed and replaced for purposes of cleaning the same, and for changing the insulating material; to provide a device that will not condense moisture upon the lining, and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings in which;

Figure l` is a perspective showing the parts disassembled; Fig. 2 a vertical section of the same with the parts assembled for use; Fig. 3 a modification of the case shown in perspective; and, Fig. 4 a vertical section of said modification.

Like numbers refer to like parts in all of the gures.

1 represents any convenient circular frame tol support the structure preferably such as shown in my nding application, Serial No. 419,785, file March 7, 1908.

2 is an outside covering for the same having a flexible upper portion contracted and secured by in said application.

5 is an annular sheet metal lining on the top of this frame, and having an inner concave margin 6 surrounding the opening therein to support a removable metallic lining 7 closed at the bottom and slightly conical, being open at the top and having an outwardly turned bead or Aflange 8 restiii in the concave margin 6 and supporting said removable lining. Between this lining and the outer covering 2 is inserted heat insulating material 9a and a pad or cushion 11 is provided filled with like material and removably placed above the described structure and within the margin 3 of the cover and secured therein by the cord 4. The upper and lower retaining material v10 a cord 4, substantially as showny and 11 of this pad are made of material porous or permeable to moisture, whereby the pad is adapted to retain the heat and at the same time permit the escape of whatever moisture may arise from the material being cooked. To' conveniently retain said material; to place the same within the device, and to remove the same therefrom as occasion requires, I provide an openwork wire basket 14, and supported within the top of this basket, by an outwardly turned iange,

'is a shallow dish or basin 15 in which maart or whole of fluidterial consisting in may be placed, and elow which solid materials suoli as vegetables can be placed iii the basket 14. On the'bottom of the lining and beneath this basket, I provide any heating body preferably an electrical heater 16, the conductor 17 of which extends upward and out over the lining and through the gusset opening of the covering. To further increase the capacity of the device for separately containing a variety of materials, I also provide an inner vessel 12 adapted to go within the lining and of substantially the same shape, adapted to receive the basket 14 and provided with handles 18 for lifting the same. The4 vessel 12 extends above the dish 15 a sufficientdistance to carry a shallow dish 13 having an outwardly extended flange resting on the top of the vessel 12, and the dish 15 also furnishes an inner closure to the vessel 12. I am thus enabled to put into the device several vessels, each containing a separate article to be cooked, two upper shallow dishes adapted to contain fluids; a basket adapted to contain solids, and when the vessel 12 is used, fluids may also be placed therein. If no uids are placed in the lower part of the basket, the heater 16 will afford sufiicient dry heat so that the-material in the lower part of the basket will be baked while the fluids in the upper dishes 15 and 13 may be kept at suicient temperature to cook the contents thereof and any steam therefrom will escape upward through the pad 9 and will not condense on the i-nterior of the lining or the material in the bottom of the basket. a separate closure for the vessel 12.

The modification shown in Figs. 3 and 4 consists of substituting for the circular case Each dish 13 and 15 also provides with fabric cover, a rectangular wooden i the lining 5 being rectangular-at the mar| gin, inserted in a groove in the upper part of the case and having a hke circular openinv with a like concave 6 a like lini 7 I niis adapted to surround the material to be cooked and closed at the top by said pad.

2. In a fireless cooker, the combination of a heat insulated receptacle, a metallic vessel adapted to be placed within the receptacle, an openwork wire basket adapted to be placed within the vessel, a removable tray or dish su ported in the upper part of the basket, an a second tray or dish supported in the upper part of the vessel above the first named tray.

3. In a-fireless cooker, the combination of a case, a horizontally d1s osed metal lining in the top of the case an having a circular materia aimons opening surrounded by a concave margin, a removable lining suspended within the case and having an outwardly projecting bead resting in said concave margin, a metallic vessel within .the lining, a heater in the bottom of the vessel, a wire basket in the vessel, a shallow tray supported in the top of the basket, a second tray suspended in the top of the vessel above the first named tray, each tray forming a closure for the vesse insulating material between the lining and the case, and a pad filled with insulatin material above the lining of said vesse and having 4. A ireless cooker, comprising a case, a removable metallic lining 1n the case, heat insulating material between the lining and case, and a removable pad filled with heat insulating material to close the top of the case.l

In testimon whereof I afiix my signature ,in presence o two witnesses.
