LOUIS, MISSOURI, A CORPORATION OF NEW JERSEY SPECIAL CONSTRUCTION FOR LININGS FOR RANGE OVENS Application filed August 22, 1929. Serial No. 387,712.

Thisinvention relates to special construction of linings'for range ovens and the primary object of the invention is to omit the zlates,.therefore making an unsanitary condition which is diflicult and inconvenient to removeyand the use of these inwardly extending shelves reduces the capacity within the oven to the extent of the added widths of the two shelves. 7

This improvement involves forming slots in the lining, the walls of the slots supporting the racks, and the present improvement is inhaving these slots extend to the outer end of the oven whereby they are open ended slots through which slots the ordinary rack can be readily inserted and removed, and the walls of these slots at the same time support the racks in its various positions against tilting and thereby spilling the contents of the utensils thereon.

Further and other objects of the present invention will appear from the following description.

" Inthe drawings Figure 1 is a perspective new of the front ends of the cooking-and broiling ovens, the

-doors-being omitted and a cooking rack? "shown in dotted lines.

FigureiJZ is a perspective sectional view of the front ends of the cooking and broiling. ovens showing a modification in the formation of the lining of the said ovens which involves the broad idea herein disclosed.

Figure 3 is'a, perspective view in section of one side of the cooking and broiling ovens oure 4 :of that side of the oven opposite to Figured.

-,Figure 6 is a detached enlarged elevation ashowing one side of the oven.

Figure 7 is a cross vertical sectional view on the line 77 of Figure 6.

Figure 8 is a horizontal sectional view on the line. 88 of Figure 6.

Figure 9 is a horizontal sectional view taken longitudinally of the forward end of the oven shown in Figure 1 with the surrounding edge of the oven modified showing part of a rack within the outer end of the oven.

Figure 10 is a top plan view of a rack involving this improvement.

Figure 11 is an end view of Figure 10.

Referring now'to the drawings, 1 is the cooking oven and 2 the broiling oven therebeneath. I

The outer frame 3 located at the outer end of the ovens is arranged in a direction at right angles to the lining 4. This frame may be permanently attached or it may-be detachable. y

In the special construction here shown the lining .4 is provided with a plurality of slots 5, and in the form here shown these slots extend outward and through the frame 3 as shown at 6, thus forming these slots with open outer ends.

'7 In the drawings is shown the ordinary form of rack 7, that is to say, a rack formed usually of wires. In the form here shown this rack is made wider than the width of the cooking oven 1 or the broiling oven 2. It will be understood by those skilled in this art that ordinarily these racks are made of a width not exceeding the distances between the linings 4 and these linings as hereto-fore constructed in the commercial ovens have inwardly' extending horizontal shelves. It is also well understood that these shelves are 7 arranged in parallelpairs and that the racks allel-shelves have been pointed out hereinbefore and it is needless to repeat them. 7

While the racks 7 are made wider than I the distance between the linings of the ovens,

yet they are made narrower than the horizontal distance between the edge walls of the slots 6 for the purpose of enabling the racks ztoibe freely moved backward. and forward in the ovens and to be freely removed when desired from the ovens.

In the construction here shown, the upper and lower walls of these slots 5 are provided with inwardly extending flanges 8, which are for the purpose of strengthening the linings and for the purpose of preventing the linings from warping when they are being enameled. This forms the subject matter of a co-pending application Serial No. 387,711, filed August 22nd, 1929, in which they are fully described and claimed and need not be further explained herein. In the construction shown in this co-pending application these slots also have communication with fines 9 located at each side of the oven. The object of these lines and their operation is also fully disclosed and claimed in the above referred to co-pending application. For the purposes of this case it is sufiicient to say that the racks 7 can be laterally moved in opposite directions and their rear ends would be thrown into the fines 9. When these racks are moved laterally sufliciently they become wedged in the oven thus interfering with their operation. In fact they become hung up in the parlance of those skilled in the art. For the purpose of insuring the even movement of these racks backward and forward in the oven I provide downwardly extending members 10 which are located (as shown in Figure 10) at its forward and rear ends, which act as stops by engagement with the linings 4 to prevent these racks from. being moved laterally sufficiently to interfere with their easy operation.

In Figures 1 and 2, the frames 3 that form a margin for the open ends of the ovens, extend at right angles to the linings 4, and the same is true with the extreme outer edge 11 that usually is made as an integral part of the frame 3. Those skilled in this art understand that the doors (not shown) close against the frame 3 and that ordinarily the edges of these doors are substantially in a line with the outer edge 11.

In Figure this frame is made up of several separate parts which are usually bolted or welded or otherwise connected together but it in nowise modifies the present improvements and need not be further specifically described since it is well understood by persons working in this art.

In Figure 4: the outer edge 11 is rounded as shown instead of being formed at right angles to the part 11 as in Figures 1 and 2 and also Figure 3.

Referring now particularly to Figure 2, it will be observed that the outer vertical edge 12 of the lining 1 is flared outwardly for the purpose of assisting any one in placing the raelts in the oven. This flared portion is also provided with lateral slots 6 which are continuations of the slots 5. The above specifieally described and shown construction of Figures 2, 3, 4 and 5 is found in practice to have several novel advantages. Among these advantages is to avoid vertical sharp edges located at the outer ends of the slots which enables the rack 7 to be more readily inserted in the'outwardly flared ends of the slots and to prevent the forming of sharp edges which makes the interior of the oven easily cleaned. By making the outwardly flared ends 6 of the front of the oven flared outwardly which provides the flared outwardly ends of the rack receiving slots leaves no ragged edges and enables the rack to move freely in the slots without any binding effect whatever.

In Figure 3 is shown a further modification in the construction of the outer ends of the linings. This modification relates particularly to the frame 3. This frame has an outwardly extending cut-out portion 3, and this cut-out portion is of a length to embrace all of the slots 5. By means of this construction the cut-out portion 3 forms a guide when placing the rack 7 in the oven.

In Figure 5 I also show the rounded end 11 instead of the right angle 11 shown in Figures 1, 2 and 3. This however is nothing more than the ordinary construction and need not be specially described.

The special advantage of the outwardly flared edge 12 is to remove the vertical edge 3 that is shown in Figure 1, thereby making it easier to place the racks within the oven.

The construction herein shown is specially adapted as an insulating lining.

An insulation 13 can be placed between the outer wall 141 of the flue 9 and the outer wall 1.5 of the range as shown in Figure 4. Or instead of having the insulation 13 then the space occupied by the insulated material 13 can be used as means for preventing the heat being readily conducted through the outer wall 15. 1

It will be understood of course by those skilled in this art, that between the cooking oven 1 and the broiling oven 2 is a suitable horizontal bottom or wall 1'.

lVhile I have described in detail the present improvement, I wish it understood that changes may be made therein without departing from the scope of the invention so long as the changes are within a liberal interpretation of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A range having a lining, the said vertical walls of the lining provided with a plurality of elongated slots arranged in corresponding horizontal planes, a vertical frame located outside of the said lining and extending in a direction transverse the said lining, said frame provided with slots corresponding with the slots in said lining thereby forming slots with open outer ends, of a substantially flat rack extending into said slots and freely movable into and from said slots and freely adjustable in said slots the rack operating substantially as described.

2. A range having an oven provided with a lining, the vertical walls of the lining having a plurality of horizontal elongated slots with open outer ends, said vertical walls having their outer ends inclined outwardly between the said slots, and a rack freely movable into and out of said open ended slots and freely adjustable in the said slots, substantially in the manner and for the purpose set forth. V

3. A range provided with an oven having a Vertical lining at each side of the oven the outer ends of said walls flared outwardly, the said walls having parallel horizontal rack receiving slots, the outer ends of said slots also formed in the outwardly flared portion and a rack of a width adapted to enter through the flared slots and freely adjustable therein, whereby the rack can readily engage the outer ends of the flared slots for the purpose set forth.

4:. A range provided with an oven having an outer inner wall and a lining for the oven separated from the said outer wall, said lining having its outer vertical portion flared outwardly toward the said outer wall, the oven provided with a rack receiving horizontal slot having its outer vertical end flared outwardly, and a rack of sufficient width to enter freely the outer flared slots and move freely backward and forward in the said oven.

5. A range having an oven comprising an outer wall having vertical end portions at the outer side of the said oven and a lining vertically arranged substantially parallel with the outer end of the said outer wall, said lining separated from the outer wall, the outer end of the said lining flared outwardly and horizontal rack receiving slots formed in the vertical lining and in the flared ends thereof, and a rack of a width to enter the flared ends of the slots and move freely therein.

In testimony whereof I hereunto aflixmy I signature.

ISAAC VERNON BRUMBAUGH.
