F 5, 6,7 and 8 are perspective details showing interlocking edge portions of. bottom and side walls ofthe structure; and

portions broken away Fig. 9 is a front elevation of, the unit showing doors for closing'the front of'the same in openposition and astove place within the compartment formed by the unit The structure comprising theunit embodying the present invention consists of atop or roof section 1, a back wallsection 2, sidewall sections 3 to the forward edges of which doors 4 are connected by hingesfi, and a bottom or floor section 6. The back wall 2 and side walls 3 are preferably formed hollow and of inner and outer sheet metal plates and 8 respectively, which are'spaced apart by wood strips 9 extending along the edges of the plates; and forming a spaeing frarne to space part the sheet metal plates forming thewall. In a like manner the back wall oiisection 2 is formed of inner and outer sheet- metal plates 10 and 11 which are spacedapart by a like wood frame 9 and the bottom or floor section 6 comprises a wood flo or 12 which is covered by an inner sheet 1netal-c0vering13 and an outer like covering 141-. 'The meeting edges of the back and side walls and ot' the floor section and these walls, are all torinedlto interlock in-such a manner that they may be readily assembled ordisassembled, and will pr'o- 'vide' air tight and water proof join'ts,; To

provide such an interlocking edge portion, for side edges are pro v ded with a aha-anal an 15 {formed er 11 eta].

1s a transverse vertical section of the channel and spaced therefrom to provide a groove 16 for Cal " joint is secured andthe parts the purpose of receiving the'edges of the metal sheets 10 and 11. This channel also extends across the upper edge of the back wall to form an edge portion for engagement with the roof section 1 of the structure.

The side wall sections 3 are formed at their rear edges with a. channel to receive the edge channel of the rear wall and this channel formed on the side walls is constructed by bending the edge portion of the metal plate 7 of'each wall against theouter side edge of the frame 9, thence outwardly longitudinally 'of the wall, and thence inwardly, it'orming a channel 19'to receive and embrace the edge channel 15 of the back wall. The edge portion of the outer plate 8 of each side wall is extended past the frame 9 and in contact with thelongitudinally extending portion or bottom of the channelformed by the inner plate 7, and-then is bent at right angles to engage the outer side of the outer flange 17 of the channel and then bent over the edge of this flange andformed inwardly against the inner side thereof, forming a loop portion 18 to embrace and strengthen the outer flange 17 of the channel 19 withinwhich the edge of the back section is adapted to fit closely. lVhen these edges are so assembled, they may be secured together detachably by means of screws 20 (Fig. 4) passing through the outer flange of the channel, through the edge portion of the back wall, and into the wood liller 90f the side wall. These screws tend to bend. the outer flange 17 of the channel inwardly against the back wall and thus a very tight are firmly held together. The channel strip 15 reinforces and stiffens the edge of the back wall to obviate liability of damage to the parts during transportation, and the channel formation on the side walls, the outer flange of which is reinforced by the overturned portion 18, also forms a strengthening and stiffening member for the edges of the side walls or sections.

The forward edges of the side wall sections are each formed by bending the edge portion of the metal plate 8 around and against the forward edge of the'filler O and thence inwardly as at 21 against the inner face of the filler, as shown in Fig. l, thus securely fas tening the forward edge of said plate to said filler, and the forward edge portion of the plate 7 is formed across and upon the inturned edge portion of the plate 8 which lies against the filler and is extended for a distance beyond the outer surface of the plate 8 and folded backwardly upon this extended portion to form a laterally outstanding flange 22 of double thickness of metal, the free edge portion'23 of the metal being formed down upon the outer surface of the plate 8 and secured thereto in any suitable manner. The

leaf of each of the hinges 5 is-passed plates 7 and 8 are thus firmly held in place upon the filler strip 9 and the forward edge of'this strip is protected and the forward edge of the wall is strengthened and stiffened by this folding over of the two edge portions of the two plates of the wall. The plate 7 is also formed with the laterally outstanding flange 22 which is adapted to overlap and lie upon the inner surface of the wall of the building within an opening in which the unit is inserted, and thus the crack or opening between the unit and the edge of the wall opening of the building is completely closed when the unit is in'place, to provide a tight joint and to assist in holding the unit inv place within the opening in'the wall.- V The doors t are attached tothe forward ec ges of the side wall sections by means of the hinges 5 with these doors lying flat against the edge face of the side walls formed by the folded over edge portion of the plate 7 One through an opening in the flange 22 and the leaf is secured in any suitable manner to the side wall by screws or other fastening means passing through the leaf and into the filler strip 9 with the leaf lying flat against the outer side of the side wall section.

The doors 4 are also preferably made of sheet metal plates 24: and 25 with the edge portions of the plate 25 folded over the edge portions of the plate 24 to stiffen the edges of the doors, and panels are provided in each door by spacing the central portion of the outer plate from the inner plate, thus providing an air space between the plates for the aurpose of preventing warping and to insulate the door against high heat within the kitchen unit. These walls are spaced apart by means of a filler frame 26 which also forms a frame around a window 27 in the door and adjacent the floor unit 6 near the lower edge of each door,'a series of openings 28 is providcd for admitting air from the room ofthe building into the compartment or interior of the kitchen unit when the doors are ti ght ly closed.

The lower edge of each side wall section 3 is formed to interlock with the sideedges of the floor section 6 and a like edge formationis providedupon the lower edge of the back wall section and the back edge of the floor section for the same purpose. The side and back walls are formed with an outer downwardly extending reinforced flange 29 and also with an inner parallel downwardly extending flan go 30, and the side and back edges of the floor section are formed with an upwardly extending reinforced flan e 31 to engage between the flanges 29 and 30 on the side and back walls. The flange 31 is formed by bending the edge portion of the sheet metal 13 downwardly against the outer edge of the floor board 12, thence outwardly and then upwardly providing a channel 32 the outer flange of'which floor section. ing the edge portion of the plate 7 outwardly of the unit and may forms a part of the flange 31, and the plate 14 is carried beyond the edge of thefloor 12 thence v b'ent upwardly against the outer face of the side flange of the chann'el'32', thence over the edge of said fla-nge'and downwardly against the inner surface thereof, to reinforce said flange and to stiffen the edge. portion ofthe The flange9 is formed by bendagainst the lower edge of the filler 9, and

"thence downwardly with its outer face in the plane of the outer face of the filler and the plate 8 is extended downwardly in contact with this outer face and folded over the clownwardly extendlngportion and over one side flange of a channel member 33 which hes 1n contact with the lower edge of the wall section. The flange-29 is thus formed of four thicknesses of metal with the edge portions 1 "of the plates 7 by the folded to give double strength and thickness to the flange 30 which is adapted to be engaged and fit within the channel 32, thus forming a tight joint between the bottom, side and back wall sections, which may be detachably secured together in any suitable manners The roof or top section 1 of the unit comprises a box 'like structure formed of a single thickness of sheet metal with a front side or panel 34 and back wall 35'and end walls 36'. The top wall 37 of this section forms the roof be inclined downwardly toward the back wall 35 so that when theunit is placed within an outer wall of a building,

front and along the ends the water will drain off. The front panel 3% and ends 36 are interlocked with the edges of the roof 37 by folding the edge portion of the metal of these walls over an upturned edge portion of the roof plate, thus forming an upstanding flange 38 (Fig. 3) across the Of the roof the flange across the front being adapted to engage the inner surface of the wall of the building when the unit is inserted in. an open ing in such a wall, to close the crack, and make a tight joint, and this flange 38 at the ends of the unit prevents the water from flowing over said ends and running down upon the outer surface of the end'walls of the unit. At the outer rear end of the unit, the roof 37 is interlocked with the wall 35 by bending the edge portionof the roof metal over an outturned portion of the plate 35, thus forming an outstanding flange 39 which serves the purpose of caves for the structure to shed the water therefrom at the outer rear end of the unit.-

A channel 40 is formed along rear edge and end walls of the lower side and back wall wall of a'buildingbut' may suitable flue of the buildin units 2 and 3, thus providing afirm seat for the top or roof section and also interlocking this section with the upper edges of the'walls of the structure. The upper or roof section is not only held firm-ly in place by this interlocking arrangement but assists in holding the'upper edges of the side and back Walls. A canopy 41 of conical. shape is provided within the interior of the box-like structure "of the roof section, with the lower edges of this conical canopy-or hood secured to the lower edges of the top section and withiits side walls converging-toward a flue or pipe Ail-which extends out through the roof 37 and is: provided with a'suitable regulating the draft through the interior of thekitchen unit. This canopy 41 forms an upwardly tapering top wall for the chamber or interior of the kitchen unit s'othat the draft created'by the flue 42 will draw off smoke, odors or fumes from the interior of the structure and will also draw odors from the room of thebuilding into therefor.

A unit structure isthusprovidedwhich may be readily placed Withinan opening in the wall of a-room of'a building to provide an extension for this room within which a stove which the unit opens and provide ventilation .of any type suitable for co'okingmay be placed, access to the unit being gained by the opening of doors which form the frontwall of the unit and close the opening in the wall of the building. The compartment formed by the unit may thus be closed up at any time and all that will be seen from the interior of the room of the building will he the front end of the unit which will have the appearance -of a cabinet set into the wall and may be made very attractive *by a proper panelling of the doors and of the front which may be mounted as shown in Figs. 1, 3 and 9, a clock {l4 and suitable switches l5 and 46 for electrical connections. 7

As this entire unit is made up of separable section-s detachablyinterlocked, the structure may be readily installed-and maybe shipped damper 43 for this flue from panel 34 within in the knock-down. The structure is also such .thatit forms a -fire proof unit particularly adapted to house a stove, the doors l may be closed and the fire confined so that no-harm i will be done.
