. JOHN .N. KNACKSTEDT, OF OMEMEE, NORTH DAKOTA. KITCHEN FURNITURE.

l atented March 13, 1906. 3

To all whom it may concern; Be it known that I, J OHN N. KNAOKSTEDT, a citizen of the United States, and a resident of Omemee, in the county of Bottineau and State of North Dakota, have invented a new and useful Improvement in Kitchen Furniture, of which the following is a full, clear, and exact description. My invention relates to kitchen furniture especially adapted for family housekeeping; and the purpose of the invention is to provide a uniformly-heated cabinet'especi ally adaptedfor use in bread-making to raise the dough.

It is also a purpose of the invention to construct the cabinet in a simple, durable, and

economic manner and so that the heat will be used to the best advantage, and the device will make bread-making easier than ordinary and more perfect and certain.

The invention consists in the novel con struction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improved cabinet. Fig.2 is a perspective view of the inner shell, the outer one having been removed. Fig. 3 is .a longitudinal section through the cabinet, thesection being taken in direction of its sides; and Fig. 4 is a vertical section taken at right angles to the section shown in Fig. 3namely, in direction of the front of the cabinet. I

The cabinet is constructed in two main sectionsnamely, anouter shell A and an inner shell B. The cabinet is shown square, as such shape is preferred; but it maybe otherwise formed, and in the drawings the outer shell consists of a removable front 0, sides a, a backa and a top a The outer shell A 1s constructed mainly of strips 10 of wood, usual furniture-lumber being employed for the purpose, and this construction is preserved with the exception of the bottom 12, whichis of sheet metal. The inner face of the sides, top, front, and back of the shell are given alining of asbestos paper 11, or other fireproof material, and also, preferably, the saidouter shell is provided with sustaining strips of metal 13, constituting framings for the slats 10. The front a of the said outer shell A is provided with a door 14 at its upper. portion, and preferably the said door is hinged to drop downward when open, and a suitable latch 20 is provided for the door. At the central lower portion of the front A of the outer shell A a second door 15 is properly hinged, and this door has a ventilated grating 16 therein and a sight-opening 17. At the side portions of the lower edge of the front a the material of the front is cut away at each side of the door 15, forming bottom openings 18 in the said front a, as

best shown in Fig. 1. In the panels thus formed at the sides of the door 15 ventilators 19 are located. In the further construction of'the outer shellAa base-board 21 is secured along the front, back, and sides, the top por- I tion of which base-board is more or less beveled, as shown best in Figs. 3 and 4.

With reference to the construction of the inner shell B, which is shown in detail in Fig. 2, said shell is preferably made of light sheet metal and comprises a front section 1), side I sectionsb, a topsection b and a rear section b but the'bottom of this inner shell B is open. At the lower portion of the shell B 'amarginal flange 23 is formed, and when the said inner shell is placed in'position in the outer shell, as shown in Figs. 3 and 4, the flanges 23 rest upon the beveled upper edges of the base-boards 21 and are suitably secured to said boards. At each side of the center of thebottom portion of the inner shell B, two

[parallel partitions 24 are placed, extendingv through the front and the rear of the said shell, and in the central portion of the top 11 of the said shell B an opening25' is made. en the inner shell is in position in the outer shell, the partitions 24 engage with the bot-tom- 12 of the outer shell and extend the full width from the front to the rear, as isshown especially in Fig. 4. The inner shell B is smaller than the outer shell A, so as to provide a continuous chamber 0 between the tWo shells extending practically from the flange 23 of the inner shell to the top of the outer shell, as is shown in both Figs. 3 and '4. A horizontal partition 27 rests on the upper-edge of the partition 24, and this horizontal partition 27 extends from side to side of the inner shell B and from its center out through the front sufficiently to have its forward edge received in the front a of the outer shell A, as is shown in Fig. 4. Thus it will be observed that a chamber D is formed atthe central lower portion of the or reticulated partition 30 is located above the horizontal partition 27, and the titions 27 and 30 are parallel.

two par- The upper artition 30 extends out at the front in simil ar manner to the lower horizontal partition 27, so that the heat-circulating chamber 0 at the front is not as deep as at other portions of the structure. The space between the two partitions constitutes a heat-conducting chamber E, and the space above the upper partition 30 constitutes the receiving-chamber E, in which the pan H is placed containing the dough, as is illustrated best in Fig. 3.

It will be observed that when the front a of the outer shell A is in place two side compartments F are provided at the bottom portion of the cabinet, and these compartments or chambers F are open at the front and may be employed as warming-chambers. It will be further observed by reason of Figs 2 and 41 that when the front a is in place front lower chambers G are obtained just back of the panels in the front containing the ventilators,

and these chambers G are closed except at their outer sides, where they connect with the side heat-circulating chambers C and where the ventilators 19 are located.

In order to strengthen the structure, bracebars 31 are usually provided at the corners, the said brace-bars being made to connect both of the shells, and in the upper front portion I) of the inner shell B an opening 32 is formed, leading into the dough-receiving chamber E. This opening 32 is preferably normally closed by two doors 33 of substantially equal size; but their combined area is less than that of the door 14, so that when the latter door is opened the doors 33 can swing outward without interruption.

The operation of the device is clearly shown in Figs. 3 and 4., as when the lamp has been placed in position and lighted the heat passes up through the opening 28 in the partition 27, into the distributing-chamber E, and then through the perforated partition 30 into the dough-receiving chamber E, passing all around and over the pan H, the latter being slightl elevated, and then the heated products o combustion pass out through the upper opening 25 in the inner shell B and around, over, and down the circulating-chamber 0 until said products of combustion find their way to the chambers G, from which they escape through the ventilators 19.

The temperature in the cabinet may be "The cabinet can be readily read upon a thermometer placed in V the outside shell A back of a transparent pane.

The device'is very simple, easily managed, and the heat can be readily regulated and is distributed in the most satisfactory manner.

placed wherever needed and is supported usually by legs 22.

Having thus described my invention, I -elaim as new and desire to secure by Letters Patent 1.
