COOK-STOVE.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed May 1, 1911. Serial No. 624,361.

T 0 all whom it may concern:

Be it known that I, JOHN B. TURBEVILLE, a citizen of the United States, residing at Cleburne, in the county of Johnson and State of Texas, have invented a new and useful Cook-Stove, of which the following is a specification.

It is the object of the present invention to provide a cooking stove, having superposed ovens, either of which may be used at will, and to provide heating means and controlling means, the controlling means serving to cut out one of the ovens, at the will of the operator.

A further object of the invention is to im prove generally, the construction of cook stoves, and to provide novel means for controlling the circulation of the products of combustion therethrough.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. 4

In the drawings,--Figure 1 shows the invention in elevation; Fig. 2 is a transverse section; Fig. 3 is a section on the line 3-3 of Fig. 2, the sifter and ash pan appearing asadded details. Fig. 4 is a section on the line 44 of Fig. 2.

The stove comprises a casing, denoted generally by the numeral 1, the casing 1 including a top 2, a bottom 3, and walls, denoted by the numerals 4, 5, 6 and 7. Located within the casing 1, adjacent the wall 4, and rising from the bottom 3, is a primary baflle plate 8, having a lateral extension 9, constituting the bottom 10 of the upper oven 11, the ends of which extend to the walls 6 and 7, the upper oven 11 comprising walls 12 and 14, and a top 15.

The invention further includes a secondary baffle plate 16, extended downwardly from the top 2, adjacent the wall 5 of the casing 1. The secondary bafiie plate 16.is equipped with a lateral extension 17, located below and spaced from, the bottom 10 of the upper oven 11.

The lower oven, denoted generally by the numeral 11, is spaced from the wall 5, from the bottom 3, from the primary baflle plate 8, and from the extension 17 of the'secondary baffle plate 16. The lower oven 11 comprises walls 18 and 19, a top 20, and a bottom 21. 9 v

The secondary bafile plate 16 and the wall 19 of the lower oven 11, together with the wall 5 of the casing 1, constitute a flue 22, communicating with the stack or stove pipe '23. In the secondary baflle plate 16, adjacent the top 2, and above the top 15 of the upper oven 11, there is a damper 24. In

the extension 17 of the secondary baflle plate 16, to the rear of the wall 14 of the upper oven 11, and in vertical alinement with the space existing between the wall 14 and the secondary baiile plate 16, is a damper 25.

In alinement with the secondary baflle plate 16 and with the wall 19 of the lower oven 11, and controlling the space between the top 20 of the lower ovenll and the extension 17 of the secondary battle plate, is a damper 26. Operating in alinement with thetop 20 of the lower oven 11, and controlling the space between the wall 18 of the lower oven 11 and the primary baflie plate 8, is a damper 27. It will be understood, without a specific description, that the several dampers above referred to, are accessible from the outside of the casing 1, as is common in the art.

Access is had to the lower oven 11, by means of a door 29, access being had to the upper oven 11 by means of a door 28, the doors 2?; and 29 being preferably, although not necessarily, mounted for vertical swinging movement, and both doors being held in closed positions by means of a catch 30, of any desired construction.

The grate is denoted generally by the numeral 36, and may be of any desired form.

This grate is supported by the wall 4 of the casing, and by the wall 12 of the upper oven 11. The grate 36 is positioned relatively near to the top 2 of the casing, as Fig. 2 will clearly show. Located below the grate 36, carried by the wall 4 of the casing, and by the wall 12 of the upper oven 11, is a pair of guides 37, a similar pair of guides 38, being located below the guides 37. Slidably mounted upon the guides 37, is a sitter, denoted by the numeral 39, and having a suitable face plate 40, constituting a closure for the opening in the casing, into which opening the sifter 39 is inserted. The guides 38 constitute a mounting for the ash pan 41, the same having a suitable faceplate 42, as

clearly appearing in Fig. 1. The space 43 below the guides 38, constitutes an ash space, and access is had to this space 43, by means of a suitable door 44. To the wall 4 is hinged a shelf 45.

In practical operation, presupposing that the parts are positioned as shown in Fig. 2, the operation of the device is as follows: The heated air and products of combustion, generated above the grate 36 will pass, in the direction of the arrows, between the top 15 of the upper oven 11 and the top 2 of the casing 1. Thence, the products of combustion will pass between the wall 14 of the upper oven 11 and the secondary baflie plate 16, thence between the bottom 10 of the up per oven 11 and the extension 17 of the bafl'le plate, thence between the battle plate 8 and the wall 18 of the lower oven 11, thence between the bottom 21 of the lower oven 11 and the bottom 3 of the casing 1, thence between the wall 19 of the lower oven 11 and the wall 5 of the casing 1, thence between the secondary battle 16 and the wall 5 of the casing, and thence into the stack or stove pipe 23.

When the circulation takes place as above described, it will be seen that both ovens will be maintained heated to a high degree. It is possible, however, to cut out both ovens. In order to efiect this result, the damper 24 is swung downwardly, permitting the products of combustion to pass from the space above the grate 36, directly into the stack 23. It is also possible, to heat the upper oven 11, without heating the lower oven 11 to the baking point. Under such circumstances, the damper 24 is closed, together with the dampers 25 and 27, the damper 26 being open. Under such circumstances, the products of combustion will pass across the top of the upper oven 11, along one side of the upper oven across the bottom of the up per oven, and thence between the extension 17 and the top 20 of the lower oven 11, into the flue 22, through the opening which is controlled by the damper 26.

Should it be desired to cut out the lower oven 11, and at the same time heat the upper oven 11, but to not so great a degree as above described, the damper 24 may be closed, the dampers 25 and 26 being opened. Under such circumstances, the products of combustion, generated above the grate 36, will pass along the top of the upper oven 11, along one side of the upper oven 11, and thence through the openings controlled by the dampers 25 and 26, into the flue 22, and thence into the stack 23.

From the foregoing it will be seen that it is possible, by manipulating the dampers, to cut out both ovens, to out out the lower oven, so to direct the products of combustion that the upper oven 11 will be heated on three sides, and so to conduct the products of combustion that the upper oven 11 will be heated upon two sides only.

It will be understood readily, that the ashes from the grate 36 will be received by the sitter 39, and that the sitter 39 may be reciprocated upon the guides 37, the minor portions of the ashes falling into the ash pan 41. If desired, the ash pan 41 may be removed, whereupon the ashes may be permitted to accumulate, to any desired extent, in the space 43, from which space, the ashes may be removed through the door 44. Likewise, should the ash pan 41 overfiow, such overflow will find its way into the space 43, thereby preventing a choking of the sitter 39 or of the grate 36.

Having thus described the invention, what is claimed is In a, device of the class described, a casing; spaced, superposed ovens therein; a primary bafi'le plate rising from the bottom of the casing and having an extension connected with the upper oven; a secondary baliie plate depending from the top of the casing to one side of the upper oven and having an extension protruding between the ovens, the secondary battle plate defining a flue at the back of the casing; there being an opening in the secondary bafile plate above the upper oven and communicating with the flue; there being an opening in the extension of the secondary baflle plate, alined with the space between the upper oven and the secondary battle plate; dampers for the openings; a damper positioned to control the point of communication between the flue and the space between the lower oven and the extension of the secondary battle plate; a damper positioned adjacent the top of the lower oven and adapted to open and to close the space between the lower oven and the primary baffle plate; and a grate positioned between the ovens and one wall of the casing, upon the opposite side of the casing from the flue, the upper oven being spaced from the top of the casing.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

JOHN B. TURBEVILLE.
