13 Claims.

This invention relates to a range adapted for- ,cooking, baking and broiling purposes.

As'now constructed, such ranges usually have a frame or a border around the oven and broiler compartments to which the doors are hinged. Modern finishing methods with porcelain enamel frequently cause such borders to warp" out of shape, and when the same are drawn into shape,

' the enamel finish is apt to chip or crack. This invention is designed to eliminate this objection in providing a door structure or closure that extends over such frames or borders.

A further feature of this invention exists in the provision of a dead air space upon the sides,

I) and the top of the oven and broiler compartmentsto confine the heat and prevent the stove from becoming excessively hot.

A still further novel feature resides in the means and manner of hinging the doors.

The invention comprises the novel structure and combination of' parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred form of this invention and in which similar reference numerals refer to similar features in the different views:

' Figure 1 is a front elevational view of a range involving this invention.

Figure 2 is an enlarged sectional view taken sub:- stantially upon the line 11-11 of Figure 1 showing the door in elevation.

Figure 3 is an enlarged sectional view taken substantially upon the line III-III of Figure 2.

Figure 4 is an enlarged fragmentary sectional view taken substantially upon the line IV-IV of Figure 3, but showing the door in open position, and in dotted lines in closed position.

Figure 5 is an enlarged sectional view taken substantially upon the line V-V of Figure 4.

Figure 6 is a fragmentary sectional view taken upon the line VI--VI of Figure 1. v Figure 7 is a view similar to Figure 6 illustrating a modified form of structure.

In referring to the drawings which illustratean embodiment of this invention, it will be noted that there has been illustrated a range having an upper oven 1 and a lower. oven 2. The upper oven 1 is adapted to be closed by a door 3 while the lower oven is adapted to'be closed by a door 4.

These doors are supported in a similar manner and involve a similar operation. It will therefore only be necessary to describe Figure 3 there is shown in onethereof. In cross section the lower oven 2 and it will be noted that there is a dead air space 5 upon each side of the same.

Each

dead air space 5 is formed by the outer wall 5a of the range, which has flange 5b and an interior an inwardly directed wall 6. The dead air spaces of the two ovens are closed at their fronts by a front frame which may consist of sheet metal or cast iron or other metal constructions. In the present instance, sheet metal plates '7 are ateral flange extending at right angles to the front face thereof for teleused. Each plate '7 has a l scoping over the interior wall ber. The outer margins against the inturned flanges wall 5a.

Each plate 7 is provided 6 of the air chamthe plates 7 .rest 5b of the outer rected rib or bead 8 adjacent each oven compartment. Each bead 8 terminates at its lower end in a rounded shoulder 9 as tions of oven doors may of illustration, there is shown plate member or lining 10 shown in Figure 4 for a purpose that will later appear. Various construcbe used, and as a matter in Figure 3 an inner to which a pair of substantially U shaped frame members 12 are attached, one adjacent each The lining 10 is provided lateral margin thereof.

with channellike guide U ways 11 which are outwardly directed and which are located within the U shaped frame members 12. The outer surface of an ornamental plate 13 or the door is formed by the like. The U shaped members 12 have upstanding bearing lugs 14'to which the door operating mechanism is pivoted.

The head 8 on the front frame extends across the top and down the sides of the oven and the channel 11 in the door is made to conform to the bead 8 as shown in Figure down a portion of the sides of the oven. The channels 11 are only enlarged as shown in Figure 3 to accommodate the bars 18 of the door operative mechanism.

In each dead air space bar 15 which is anchored rear wall of the range by 16. The forward end of wardly inclined as indicated at 1'? in and extends through a. su

5 there is a horizontal at its rear end to the means of a'coil spring each bar 15 is down- Figure 4 itable slot in the plate with an outwardly di- I 6 across the top and U insantiary.

as shown in Figure 4. Each bar 15 is pivoted at its forwardly inclined end to a ing 14 on the adjacent frame member 12. The aforementioned bar 18 is pivoted coaxially with each bar 15. The upper end of each bar 1 8 extends through a slot in the plate 7 and, is retained by a small stud 19 which is adapted for engaging the-plate 7 adjacent said lug for anchoring the bar 18 thereto. It will be noted that the channel guideways 11 receive the bars 18 and that the ribs 8 also extend into these channel guideways 11.

- will engage or abut the shoulder 9 on the lower endof the ribs 8.

With referencetoFigure 3, it will be noted that the door frame 12 overlaps the edge of the front frame as indicated at 21. This overlap and the fitting of the channel 11 over the bead 8, forms a seal for the oven which retains the heat and,

prevents the escape of steam and vapor from the oven, which frequently discolors the front frame of the stove and which is often more or. less Inits horizontaloropenpositiontheovendoor 4 is held or supported at two spaced points,-one point is at the axis 20 of the pivot that supports the vertical bar 18 and the other point is at the shoulder 9. Consequently the door will be firmly held in such horizontal position. It is evident that as the door is pulled downwardly or outwardly into its open position, the bars 15 will be pulled outwardly as shown in Figured and put the springs 18 under tension. However due totheinelinedarmportionl'1suchsprings will not be able to swing the doors shut from their open position. However, when an oven door is swung upwardly a short distance, to bring the parts oil dead center, the springs 18 will become effective for automatically pulling the doors into their closed positions.

In Figure 7, there is illustrated a modifiedform of door structure and front frame. In that formthe front frame is indicated by the reference la. It has an integral head 8. The door embodies an. angular border frame 12a, which overlaps the ends of the front frame as indicated at 210. The front 13:: is attached to one flange of the frame and'the inner liner 10a is .secured or welded to the other flange of the frame. 7

From the foregoing, it will be apparent that the border around oven doorshas been eliminated since the doors completely cover the front frame 'andtheconstructionissuchthattheovensare effectively sealed by the doors. The novel fea-' ture of hinging the doors whereby theymay be supported and maintained in a horizontal position to facilitate the entrance or removal of foodstuffs from theovens is also important. It will be appreciated that the novel hinge construction for the doors will automatically swing thesameintotheirclosedpositionsafterthe same have been elevated a short distance from theirhorizontal positionsdnetothe action of the springs-18. This will-of course relieve the I 1,985,887 '7 when the door is swung to its open position.

closing the doors which are frequently quite heavy. It will further be evident that the doors are flush with the outer walls of ranges creating a neat and smooth finish.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
