DETACHABLE BOTTOM FOR OVENS OR BROILERS Gustav Klein, Melrose Park, 'Pa., assignor to Caloric Stove Corporation, Philadelphia, Pa., a corporation of Pennsylvania Application March 22, 1948, Serial No. 16,203

2 Claims.

it is' not readily accessible for adjustment and cleaning without removal of the bottom wall of the oven compartment. Also, in cooking stoves, foodmay spill andgrease may drip on the bottom walls of the oven and broiler compartments and where such bottom walls are not readily removable, keeping these bottom walls clean is difficult. In order to preventwarping, the bottoms of conventional stoves aresecurely locked in position and can, therefore, only be removed and reinstalled by the exercise of skill and efiort beyond those of the average householder.

It is therefore the object of the present invention to provide an improved stove structure whereby the bottom of the oven compartment is adequately secured against warping and may be removed and reinstalled without any skill and with very little effort, whereby access may be had to the burner and whereby the oven compartment bottom may be easily cleaned.

In the accompanying drawings:

Fig. 1 is a diagrammatic front elevational View of a cooking stove.

Fig. 2 is an enlarged vertical sectional view,

taken on a plane at a right angl to line 2-2 on Fig. 1, showing the detachable bottom wall structure embodying my invention.

Fig. 3 is a section on line 3-3 on Fig. 2.

Figs. 4 and 5 are similar to Fig. 2 showing the manner in which the detachable bottom wall may be removed and installed.

The stove shown in Fig. 1 includes an oven compartment Iii, a broiler compartment l2, and storage compartment [4. Since the structure of the stove, except as hereinafter described, forms no part of the present invention, it is not shown nor described.

As shown in Fig. 2, the detachable bottom includes a Wall I6 having front and rear pendent flanges l8 and 20 which are adapted to rest on front and rear horizontal ledges 22 and 24 carried by the inner faces of the front and rear walls 26 and 28 of the stove, respectively. Measured from front to back, the bottom [6 is shorter than the distance between the front and rear walls 26 and 28 so as to leave room for installation of an arcuate flat spring 30. The flat spring 30 is suitably secured as at 32 and its ends 34 slidably bear against the rear pendent flange 20, as

best shown in Fig. 3. The space between the pendent rear flange 2B and the rear wall- 28 is closed by means of a strip 36 which may be a separate piece suitably secured in position or which, as shown, may be part of the ledge 24. Conveniently, the ledge 24 is secured in position by the bolt 32 which also secures the spring 30in place.

The front wall 26 carries" a horizontal,- inwardly projecting strip 31 which overlaps the front edge of the bottom IS and serves as a keeper to holdthe bottom iii in position. The strip 31 may be a separate piece or it may be part of the supporting ledge 22.

The bottom It is also provided with a manipulating handle 38 which is preferably recessed, as shown, so as to be flush with the upper surface of the bottom of the oven.

The bottom It may, conventionally, be provided with a second Wall 40 which is spaced from, and covers a major portion of the underside of the bottom H5. The wall 40 is secured to the underside of the bottom 16 as at 42. The rear edge of the wall 40 rests on the supporting ledge 24, as shown in Fig. 2.

To remove the oven bottom [6 from the position of Fig. 2, the operator grasps the handle 38 and pushes the bottom I6 rearwardly, or to the right in Fig. 2, against the tension of the spring 30, until the front pendent flange I8 clears the keeper 36, as shown in Fig. 5. The front edge of the bottom It is now raised to the position of Fig. 3 and the bottom is pulled out through the front access opening of the oven compartment.

i After it has been cleaned, or after the burner has been serviced, the bottom It is reinstalled by pushing the rear edge thereof, against the action of the spring 3|] until the inner, vertical front edge of the bottom [6 again clears the keeper 31. The front edge of the bottom [6 is now moved to a position under the keeper 3! with the flange l8 resting on the supporting ledge 22 as shown in Fig. 2. In this position, the spring 30 urges the bottom I6 forwardly, or to the left as viewed in Fig. 2, and thus firmly holds the bottom in position.

The bottom of the broiler compartment is preferably constructed in the same manner but since the structure would be identical with that shown for the oven compartment, no further illustration or description is needed.

Also, While in the structure shown, the spring is on the rear wall, it is Within the scope of my invention to place the spring 30, the rear ledge 24 and the strip 36 on one of the side Walls of the oven compartment and the supporting ledge 22 and the keeper 3'! on the opposite side wall.

The space between the walls It and 40 is filled with any suitable insulating material thus preventing overheating of the portions of the wall I6 directly above the burner.

By the arrangement shown the front and rear marginal portions of the bottom are engaged by the overlapping strips 36 and 31 (the clearance shown between the strip 36 and the adjacent end of oven compartment bottom being very small) and thus any tendency of the bottom to warp when heated is counteracted. In other words I have produced a novel structure in which the bottom of the oven compartment is protected against warping and is completely detachable.

What I claim is:

1. A wall structure defining a compartment having'a bottom opening, a closure for said opening, a U-shaped bracket carried by each of two opposite walls of said compartment with the bights of the U-shaped brackets abutting said walls, the length of said closure being slightly less than the distance between the juxtaposed ends of the upper limbs of said brackets and the spaces between the upper and lower limbs of the brackets being slightl larger than the thickness of said closure whereby on being tilted, one marginal portion of the closure can be inserted into one of said U-shaped brackets and then the opposite marginal portion can be inserted into the other of said brackets, whereby the closure is supported on the lower limbs of said brackets with the upper limbs of said brackets overhanging said marginal portions, and a spring carried by one 4 of said walls and operative, when said closure is supported by said brackets, to bias said closure against the opposite wall.

2. A wall structure defining an oven compartment having a top wall and vertical walls and having a bottom opening, a first supporting ledge carried by and projecting inwardly from a first vertical wall, a second supporting ledge carried by and projecting inwardly from a second vertical wall opposite said first vertical wall, a keeper carried by said second vertical wall and projecting inwardly therefrom in vertically spaced relation to said second supporting ledge, a closure for said bottom opening, the length of said closure being less than the distance between the inner edge of said keeper and the first wall so that by tilting said closure one marginal portion thereof can be inserted between said second ledge and said keeper so as to rest on said second ledge, and the other, opposite marginal portion of said closure can be lowered to rest on said first ledge, and a spring carried by one of said walls and operable, when said closure is seated on said ledges, to engage the adjacent marginal portion of said closure and to bias said closure toward the opposite wall.
