CINCINNATI, OHIO, AS$IGNOR TO THE E.- n. nUnNnrnLn 00., or CINCINNATI, OHIO.
PORTABLE KNOCKDOWN OVEN.
Specification of Letters Patent.
Patented Sept. 3, 1912.
Application filed February 5, 1910. Serial No. 542,355.
' To all whom. it may concern:
' embodying my improvements.
' with Be it known that I, \VAL'rnn E. Hunnn new, of Cincinnati,
in the county of Hamih ton and State of Ohio, have invented certain new and useful Improvements in Portable Knockdown Ovens; and Ido hereby declare the following to be a full, clear, and exact description of vthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in portable ovens and particularly to those of the knockdevn'oi: collapsible type,the object of the invention being to provide an oven of the character above mentioned which can be easily and quickly assembled by an inezgperienced person and which, when assembled 'will be strong and durable.
With this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claim.
In the accompanying drawings, Figure 1 of an oven Fig. 2 is a transverse vertical section. Fig. 3 is a horizontal sectional view, and Figs. 4 and 5 are detail views.
1 represents the top sheet of the oven provided at its ends with depending straight flanges 2'and 'at its front and rear edges flanges 3, the latter having upturned flanges 3 at their free edges. The front and back sheets 4 and 5 are provided at their upper edges with flanges 6 formed by bending the metal upon itself. In asis a'longitudinal sectional View 'sembling these parts, the flanged upper edges of the front and back sheets are slid into the grooves formed by the flanges 3, 3'v-at the front and back edges of the top sheet 1. ".The ends of the front and back sheets are formed with flanges 7 and the end-sheets 8 ofthe oven are provided at their vertical edges with flanges 9 -10 which form grooves into which the flanges 7 on the vertical edges of the front and back sheets are received when said ends are slid to their normal positions to form the ends of the oven. The upper ends of said end sheets 'will become disposed inside of the depending flanges 2-of the top sheet and may be bolted thereto.
The front sheet 4 is made with an opening 11, around which an inwardly projecting bead 12 is formed. This opening is closed by a hinged door 14.
The front, back and end sheets of the oven are provided at their lower edges with inwardly and upwardly projecting. flanges 13 formed by bending the metal upon itself. The bottom sheet 15 of the oven is protop lining sheet 20 is located under the top oven sheet and spaced from the latterby means of upturned flanges 21 on the lining sheet. End lining sheets 22 are disposed adjacent to the end walls of the oven and spaced from the latter by means of flanges 23. Fhe end lining sheets 22 rest at-ztheir lower ends against thebottom oven sheet 15 and hear at their upper ends against the top lining sheet 20,said end lining sheets so as to effectually prevent any vertical displacement or rattling thereof. The top and end lining sheets bear against the rear lining sheet and prevent displacement of the latter,
is prevented by the beads 12. door opening. I a
From the construction and arrangement of partsas abovedescribed, it will 'beseen oven and its lining can be easily and quickly ture without the necessity for the emp1oy-' ment of bolts orrivets except possibly the bolts which secure the depending flanges of the oven. I
The end lining sheets are provided with that the various members composing the.
assembled to form a substantial oven struca at the ends of the topwith the end sheets v vided along its several edges with straight and space the 'lining sheet therefrom. A-
thus retaining the bottom oven sheet in place 4 while displacement of the end lining sheets around the g ribs for supportingerack 24 and a deflector 25* over the openingin the bottom 0t thee:
oven, and said rack and. deflector also assist in preventing displacement of the end lining sheets.
Having fully described my invention \Yha t I claim as new and desire to secure by Letters-Patent, is,
A portable knock down oven comprising end, front and back members, each having an inside upturned flange atits lower edge forming-a groove, the front and back members having detachable interlocking connection with the end members, a bottom memrwr'provided at its four edges with depending flanges resting in the grooves at the lower edges of the endand front and back members, a top member having detachable interlocking connection 'With the front and back .members, a top lining sheet having upturned flanges, the free edges of all of which engage the underside of the top member but have no connection with the end and back members, a back lining sheet extending from the. bottom member to the top member With its upper edge behind the rear edge of the top lining sheet, and end lining sheets extending from the bottom member to-the top lining sheet and from the back lining sheet to the front member.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses v r WALTER E. HUENEFELD. Witnesses:
R. S. Fnnooson, S. E. NOTTINGHAM.
