Oct. 20, 1936. J. TELLER ET AL COOKING S I'OVE AND RANGE CONSTRUCTION Original Filed Dec. 15, 1932 Patented Oct. 20, 1936 UNITED STATES PATENT OFFICE COOKING STOVE AND 'RANGE CONSTRUCTION Jacob Teller, New Rochelle, N. Y., and Arthur P. Schulz, Rockford, Ill., assignors to Teller Stove Designing Corporation, New York, N. Y., a corporation of New York 8 Claims. (Cl. 126-340) This invention relates to cooking stove and range construction, and is a division of our original application Serial No. 647,036, filed December 13, 1932. w

The particular features of the present invention reside in the specific oven structure, and in the arrangement of the cooking vessel rack, whereby said rack, pivoted upon a vertical axis within the oven compartment, may be interconnected with the oven door in such'manner that, when the door is opened, therack is oscillated upon the pivots, and the supports for the cooking vessels carried thereby moved out of the oven into a position conveniently accessible to the person using the range.

A further feature resides in mechanism carried by the oven door and selectively connectible with the swinging rack, to the end that'the oven door may be opened or closed with or without simultaneous operation of the rack.

These and many other features of advantage will be apparent to those familiar with the operation of such apparatus, and the various objects will become quite evident upon reference to the accompanying drawings and specification.

In the accompany drawings:

Fig. l is a front perspective view of one form of the invention, and showing the oven doors open;

Fig. 2 is a vertical transverse sectional view of a preferred form of the range on substantially the line 22 of Fig. 3, showing the oven door open;

Fig. 3 is an enlarged perspective detail view of the oven section of the range, with the door open to illustrate the rack and door structure with cooperative mechanism;

Fig. 4 is a vertical sectional view through a portion of the door on substantially the line 44 of Fig. 3.

Fig. 5 is a detail sectional view through the rack support.

Fig. 6 is a horizontal section taken through the range on substantially the line 66 of Fig. 3, and

Figure '7 is a detail view similar to Fig. 4, but

showing the parts arranged so that the shifter plate renders the door and rack parts relatively inoperative.

Referring now to the drawings by numerals of reference, I, designates generally the range, having the usual sides 2, back wall 3, and the front, which latter is closed by a series of doors and panels indicated at 4, 5, 6 and 1 respectively.

The insulated cooking top 8 of enameled sheet metal or other suitable material, has therein, a plurality of openings 9, according'to an arrangement peculiar to this invention, the particular function of which will be apparent as the description advances, and as more particularly set forth in our original application hereinbefore-referred to.

Specifically, the openings 9 are arrangedin the form of the letter L, the long leg of which lies toward and parallel with the rear edge of the cooking top 8, while the shorter leg lies adjacent to and parallel with the right hand edge of the cooking top 8 thus providing a rectangular working top space 10, surrounded on two sides by the series of openings 9, .beneath which aresuitably supported the burners -I I, said openings having utensil supporting grids l2.

Referring at this time to Figures 2 and 6, it will be observed that the range is divided into a plurality of compartments l4 and Hi, the former constituting the combined oven and broiler compartment, while the latter constitutes an L-' shaped space which underlies the openings in the cooking top, and in the upper portion of which L-shaped compartment, are suitably supported the burners ll.

These compartments M and I5, are defined by a longitudinal insulated partition I6 and a transverse insulated partition ll, the latter terminating short of the back wall 3 of the range, each of the partitions terminating at a point above the bottom l8 of an auxiliary compartment l9 which is provided with trackways for a sliding drawer 2|, the front of which latter takes the form of the panel 6, above referred to.

As distinguished from ovens of the usual character, the present oven compartment I4 is elongated in form, and relatively shallow as shown in Figure 6, the greater length being in the direction of the width of'the range as shown. By'

this arrangement and form of oven, we are able to obtain an oven of, a capacity substantially that of an oven such as employed in the usual range, in which it extends throughout the depth of the range body.

At the same time, as distinguished from ranges of the ordinary type, the top of the oven extends up to the cooking and working top, without the intervention of the regular burner compartment. This of course, is permitted through the arrangement of the series of burners to the side and back of the upper portion of said oven.

By the arrangement shown, not only are the burners so positioned that they permit elevation of the oven and broiler compartment H to an accessible working position, but at the same time, an insulated working space H), convenient to ment which may serve for any purpose for which it may be intended, and the panel I, on which are mounted the handles for the burner valves or for electric switches, when the range is utilized as an electric cooking apparatus.

These panels and doors have their adjacent edges in substantially abutting relation, their outer surfaces being in substantially the same plane and presenting a plain flush outer face. The outer lateral edges of the several doors and panels, preferably extend to the side edges of the frame 23 so that no parts of the latter are visible.

The particular features of the present invention reside in the oven and broiler compartment rack and operating mechanism, more clearly shown in Figures 3, 4 and 7. Referring especially now to Figures 3 and 5, it will be observed that there is provided a rack support comprising a vertical rectangular sheet metal frame 24 which has at its upper and lower corners, at one side of said frame, a pair of bearing pins 25 and 26 respectively which pins have their hearings in the upper and lower top and floor plates 21 and 28 respectively of the oven compartment 14%, permitting the rack to be swung in an arc of a circle within said oven.

It is to be particularly noted that the bearings for the rack are positioned on an axis located forward 'of and at one side of the oven compartment, as more clearly illustrated in Figure 6, or in other words at a point closely adjacent the corner of said oven in proximity to the oven door hinge, for purposes which will be presently observed.

Specifically, the sheet metal frame 24 has its side frame members 30 provided with a vertical series of recesses 3| formed by punching through the sheet metal frame members in opposite directions at spaced intervals to provide a vertical series of lips'32, which cooperate with a finger or hook 33 and brace 35 to maintain the said tray support in proper position upon the swinging rack. The broiler pan which is removably mounted upon the support 34 is shown at 36, while an additional cooking vessel rack is shown at 31 the latter also being removably supported upon the swinging rack by means similar to that for the broiler pan support. a

As will be more clearly observed from an inspection of the view in Figure 6, in which the movable partsare shown in full and dotted lines, the arrangement of the mounting of the swinging frame is such that it may be conveniently swung from a position entirely within the oven, to a position such that the pans and supports carried thereby may be moved entirely out of the oven.

The rack is so constructed, that it may be operated either through an operative connection with the oven door 4, or independently thereof, and to this end, we provide the selective mechanism to be now described.

Rigidly attached to the lower' corner. of the rack 24, on the axis of the lower bearing 26 is a spring metal arm 38, which lies substantially parallel with the long side of the pan support 34, said arm at its outer end having a lateral stud 50 carrying a pair of anti-friction rollers 4|, which are adapted, when desired, to cooperate and ride in the'channels 42 of a guide member 43 rigidly secured to the inner face of the door 4 toward its lower edge.

By this construction, it will be manifest that when the door is closed and opened, the rollers M on the end of the spring arm 38 may ride in the channeled guide member 63, resulting in the swinging of the rack 24 to bring the supports carried thereby, into and out of the oven simultaneously with the movements of said door.

, the,oven door 3 without at the same time swinging the rack 2t, and to permit of such operation,

we provide a selective mechanism shown particularly in Figure 4. This mechanism comprises a lever 46 pivoted intermediate its ends on a pin inclined shifter-plate 47, which as shown in Fig.

3 normally extends through an opening 50 in the inner plate of the door and is disposed outside the space between said door plates due to the action of a coiled spring &8, the upper portion of one leaf of which engages the upper end of lever :84 and urges it into the position indicated in Fig. 7. In such position, the shifter plate extends over the entrance to the guideway member 43, and guides 'the,rollers M on the arm 38 over, instead of into said guideway.

Under normal operating conditions, the parts are in the position shown in Fig. 7, that is, with the shifter plate 47 projected so that the rear edge thereof extends over the entrance to the channeled guide member 43. As now positioned,

. when the door is opened, the said anti-friction the door may open without imparting any movement to said rack and the parts carried thereby.

However, when it is desired to cause the simultaneous operation of the rack and door, that is to have the rack swing out of the oven when the door is opened, the operator by pulling downwardly on the handle 52, causes the inner end to engage the upper end of the lever M, moving said lever on its pivot 45 against the action of the spring 48 from the full line position shown in Fig. 7 to the full line position shown in Fig. 4, at which time, the rollers 4! will be permitted to ride into the entrance 5! of the channeled guideway 43. Opening of the door 4 outwardly into the position shown in Fig. 3 where ready access may be had to the articles disposed upon the racks or broiler. Referring to Fig. 2, the broiler burner is shown at 60 and the oven burner at 6|.

While it is preferredto impart swinging movement to the rack through the connections with the door as hereinbefore described, the rack may be swung independently of the door. Thus, as indicated in Fig. 1, wherein the door 4 swings about a horizontal axis, the rack or ,frame 24 may be swung into and out of the oven compartment by hand.
