The vertical edges of the four side the door being shown ina closed position and pieces 1, 2, 5, and 6 are formed tubular-like the binding-nut and upper corner-washer reand inwhat may be termed, three-quarter" moved; Fig. 8, an enlarged top view of the tubes,unbrokeninlengthandextendingprac- 5o oven with its top and racks removed, and tically from top to bottom of the oven at the loo corners thereof, as indicated by the figures 22 and 23, the size or diameter of the tubes 22 being somewhat less than that of the tubes 23, so that they fit nicely on the inside of the latter, the curls being so formed that when the walls are assembled together the edges of the outer tubes are in close contact with their cooperating walls and form a substantially firm and non-collapsible frame,whereby when the oven is assembled for use a rigid and substantial structure is produced and whereby the rickety construction common to all other knockdown ovens is overcome.

\Vhen the oven is to be assembled, one of the sides and one of the ends are first put together by inserting one of the smaller into one of the larger tubes and pressing them to place. Then a third side or end is connected in the same manner, after which the fourth side or end is joined to the other three, and the sides and ends then form a connected frame ready to receive the top and bottom, both of which are cut out'at their corners, as shown at one of the same in Fig. l, to accommodate the tubes 22 and 23. The bottom is then placed in position, with its verticallyflanged edges overlapping the sides and ends. Rods 2i, having heads 25and washers 20, are next inserted through the tubular corners, the said washers being provided with extensions 27, which overlap the corners of the bottom. The top is then placed in position and other washer 26 overlap the corners in the same manner as at the bottom. The upper ends of the rods 2-1- pass through the top washers and are screw-threaded to receive nuts 28, by which means the whole structure is firmly bound together.

I am aware that it is not new to construct ovens in knockdown manner, and do not, therefore, broadly claim such construction, and I especially disclaim the constructions shown and described in United States Let tors Patent Nos. 2at9,84:3, $3,419, and 545,511. It is obvious, however, that the details of construction as I have described them herein may be modified without departing from the spirit of my invention.

The advantages of an oven such as I have shown and described herein are well known to the trade and lie in the fact that they are much more convenient to handle, require much less room for storage, cost less for transportation, and that they can be packed and stored in pasteboard boxes, whereby they can be preserved in good salable condition for an indefinite period of time; butup to the time of my present invention, so far as I am aware, no such oven has been produced which has been entirely satisfactory.

What I claim as new, and desire to secure by Letters Patent, is

1. A domestic oven in which two edges of two of its walls terminate in tubular-like curls or hollow beads and in which two edges of, two of its other walls likewise terminate, one set of said curls incasing the other set thus uniting the said four walls together in a noncollapsible manner, one of said walls having a door-opening and a door, said door, and three of said walls, each being provided with a lining secured thereto, removable therewith and forming an air-chamber between, in combination with a top wall, and a bottom having an opening for the admission of heat to the oven, and means for connecting said four walls and said top wall and bottom together, whereby a rigid separable structure is produced which can be readily put together and taken apart, and when in the latter condition can be packed in a surfacespace represented by the dimensions of the largest wall of the oven, substantially as and for the purpose set forth.

2. A domestic oven in which the vertical edges of its two side walls terminatein tubular-like curls or hollow beads and in which the vertical edges of its two end walls likewise terminate, one set of said curls incasing the other set thereby uniting the said four walls together in a non-collapsible manner, one of said end walls having a door-opening and a door, the door, the opposite end wall and the two side walls each having a lining secu red thereto, removable therewith and forming an air-chamber between, in combination with a top having a lining forming an air-chamber between, a bottom provided with an opening for the admission of heat to the oven and means for connecting said top and said bottom to said walls, whereby a rigid separable structure is produced which can be readily put together and taken apart, and when in the latter condition can be packed in a surface-space represented by the dimensions of the largest wall of the oven, substantially as and for the purpose set forth.

A domestic oven in which two edges of two of its walls terminate in tubular-like curls or partial tubes, and in which two edges of two of its other walls likewise terminate, one set of said curls incasing the other set thus uniting the said four walls together in a noncollapsible manner, one of said walls being provided with a door-opening and a door, said door and the other three walls each having a lining secured thereto, removable therewith, and forming an independent air-space between, in combination with two other walls adapted to register with the said four walls, bolts which pass through said curls and which are provided with washers at either end thereof, said washers having extensions overlapping the corners of the oven, and nuts to engage said bolts, whereby the structure is bound firmly together, and whereby it can be readily taken apart and packedin a surfacespace represented by the dimensions of the largest wall of the oven, substantially as and for the purpose set forth.

4. A domestic oven in which two edges of two of its walls terminate in tubular-like curls or partial tubes, and in which two edges of two of its other walls likewise terminate, one

set of said curls incasing the other set thereby uniting the said four walls together in a noncollapsible manner, one ofsaid walls being provided with a door-opening and a door, said door and the other three walls each having a lining secured thereto, removable therewith, and forming an air-space between, in combination with a top wall, and a bottom wall, each having their edges flanged at an angle to their flat surfaces; said flanged edges overlapping the said other four walls and the said bottom wall having an opening for admission of heat to the oven, washers located at and overlapping the corners of the oven, bolts which pass through said washers and through said curls, and 'nuts engaging said bolts, whereby the structure is bound firmly together, and whereby it can be readily taken apart and packed in a surface-space represented by the dimensions of the largest wall of the oven, substantially as and for the purpose set forth.

5. A domestic oven in which two edges of two of its walls terminate in tubular-like curls or hollow beads and in which two edges of two of its other walls likewise terminate, one set of said curls incasing the other set thus uniting the said four walls together in a non-collapsible manner, one of said walls having a door-opening and a door, in combination with a top Wall, a bottom having an opening for the admission of heat to the oven, a deflector mounted above said opening, and means for space represented by the dimensions of the largest wall of the oven, substantially as and for the purpose set forth.

6. A domestic oven consisting of two side and two end walls, one of said end walls having an opening and a door adapted to close the same, a top wall and a bottom having an opening for the admission of heat to the oven, and adeflector mounted above said opening, the said top wall, the said two side walls, one of said end walls and the said door each having separate linings secured thereto and removable therewith, and each having an "airchamber between, in combination with means for removably securing said walls and said bottom together, i-n a non-collapsible manner,

whereby a rigid separable structure is produced which can be readily put together and taken apart, and when in the latter condition can be packed in a surface-space represented by the largest wall of the oven, substantially as set forth. v ISAAC, KINSEY. lVit-ncssesi ED L.
