OVEN.
Original application filed April 2, 1921,
To all whom it may concern: Be it known that I, 'J'osnrn F. LAMB,'3, "citizen ofthe' United States, and a resident of New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvementsin Ovens, of which the following isa specification.
This application is a division of my oopending applicationSerial No. 458,105,filed April 2nd, 1921, covering improvements in a" range.
The present invention relates to the oven, and has as its object to provide a device of this sort having various features of novelty The present invention contemplates an oven which is veryeificient in operation, simplein construction, and. which may be economically manufactured.
In the accompanying drawing, wherein I have shown for illustrative purposes one embodiment which the invention may take,
Fig. 1 is a vertical View taken centrally and longitudinally through my improved oven- Fig. 2 is a front view thereof with the door removed and with a portion of the oven in vertical transverse section; and
Fig. 3 is a perspective view of the corner frame of the oven.
Referring to the drawing in detail, it will be seen that the frame 5, which constitutes the corner irons for theoven, comprises two members 10 of similar construction each being formed of an angle iron bent into three-sided rectangular shape. These members are suitably tied or secured together as by the angle iron 11. The oven has an outside shell consisting of sheet metal side anels 12 fitting within the respective corner irons 10; top and bottom anels' 13 with their edges turned to form anges 14 which abut against the inside surfaces of the side.
panels 12, and a rear panel 15 secured in position forwardly of the rear edges of the side panels so as to leave a space 16 behind the oven through which the electric conducting Wires 17 may be led.
This outer shell is lined with suitable insulating material 18 which may be in the form of blocks or slabs. .The numeral 19 indicates the inner lining or shell of the oven, the top, bottom and side walls of which are preferably formed of a single piece of sheet metal bent into hollow rec- Serial No. 458,105. Divided and this application filed August 1, 1922. Serial No. 578,980.
tangular shape. Each of these walls has a concave portion or depression 20 which serves to space the other portions of the lining from the insulation material 18, thus providing air spaces 21 which aid in heat insulating the inner linmg. The depression inthe top Wall of the inner lining may be omitted if desired. The depression in the (ill bottom of the lining forms a well or cup I which catches the products of condensation, such as water and grease, and thus prevents them from running out of the oven. The heat within the oven tends to vaporize these drippings especially when the heating unit is immediately above the well, as shown in Figs. 1 and 2. The rear wall 23 of the inner lining is of sheet metal and is Welded to the other walls. Preferably, this rear Wall is spaced from the insulating material 18. 25 indicates the front frame of the oven which may be secured to the forward ends of the corner irons by bolts 26.
It will be noted that, surrounding and welded to the forward end of the lining 19, is a sheet metal throat piece 27 the outer edge of which is bent to form a lip taking into a groove 28 in the front face of the frame 25. The inner lining or shell of the oven may be removed as an entirety by merely taking out the bolts 29 and then drawing the lining forwardly through the frame 25. Owing to the-fact that the insulation 18-is in the form of self sustaining slabs or blocks, this insulation will not be disturbed when the lining is removed. Hung on each side of the oven in any suitable manner are racks 30 having suitably spaced cleats 31 for supporting shelves or cooking utensils. 32 designates an electric heating unit which is placed in the lower part of the oven when baking is desired. This unit may be positioned on the topmost cleat when the food is to be broiled. The heating unit 32 is provided with terminals 33 which connect up with terminal plugs 34 in the rear wall and the lower portion of the oven when the heating unit is slipped into place on the lowermost cleats. When the heating unit is on the uppermost cleats, the terminals 33 have electrical connection with the terminal plugs 35.
The door of the oven, which may be hinged to the frame 25 in any suitable manner, consists of a casting 37 having a front panel 38; a lining 39, and heat insulating material 40 interposed between the lining and the panel. The edge of the lining 39 is turned over so as to provide a tapered portion corresponding to the taper of and adapted to snugly lit in the throat 27 when the oven door is closed.
It is, of course, o-bvious that the invention is susceptible of various modifications and changes which are Within the spirit of the invention Without departing from the scope of the following claims, it being understood that the present disclosure of the invention is by way of illustration only and it is not to be taken as restrictive of my conception.
I claim as my invention 1. An oven including an outer shell, an inner shell, heat insulating material therebetiveen, corner irons on the corners of said outer shell, a front piece covering the tor- Ward ends of said inner and outer shells and said insulating material, and means for securing said front piece to said corner irons.
2. An oven including an outer shell, an inner lining, heat insulating material therebetween, and means for spacing, at least in part, said lining from said insulating inaterial to provide heat insulating dead air spaces.
8. An oven including an outer shell, an inner lining, and heat insulating material therehetween, said lining having depressed portions contacting With said material and spacing the remaining portions therefrom to provide dead air spaces therebetWee-n.
a. An oven including two similar corner pieces each formed of an angle iron bent into three-sided rectangular shape; an outer shell consisting of top, bottom and side panels the edges of which fit within the angles formed by the webs of said corner pieces and a back panel fitting Within the above-mentioned panels; an inner lining. and heat insulating material between said shell and lining.
An oven including an outer shell, an inner shell, and self sustaining slabs of insulating material therebetiveen, said lining having depressed portions directly engaging said slabs of insulating material and spacing the remaining portions of the lining from said material to form dead air spaces therebetween.
