COMBINED STATIONARY AND ROTARY SHELF FOR STOVE OVENS.

Application filed Ma 11, 1927.

Our invention relates to a combined stationary and rotary shelf for stove ovens.

The object of our invention is the provi sion of ashelf for stove ovens to be supported bythe usual shelfsupports. within the oven, and when supported thereby with one side up, it will provide a rotary shelf, and, when supported thereby with the other side up, it will provide a stationary shelf.

A further object of the invention is the provision of a stove oven shelf which consists of two shelf members, one of which is rotatably supported by the other, and'which latter is supported by the usual .oven shelf guides whether the device is to be used as a rotarv shelf or a stationary shelf.

A still further object of the invention is.

to provide the rotary shelf member in the upper face of its outer ring member with a plurality of finger or tool engaging recesses to facilitate rotary movement of the rotatably mounted shelf.

A still further object of the invention is the provision of a bearing ring forming a part of the stationary shelf member upon which the rotary shelf member isrotatable.

A still further object of the invention is the provision of a pivot pin which will prevent spreading or detachment of the two shelf members.

A still further object of our invention is the provision of a combined stationary and rotary shelf for stove ovens, which possesses advantages in points of simplicity and efli'-.

ciency, and, at the same time proves itself comparatively inexpensive in cost ofmanufacture. With the above and other objects in view, the invention consists in the novelfeatures of construction, arrangement and'combination of parts herein after more fully described and finally pointed out in the claims hereto appended. i

7 Drawings. Fig. 1 is a top plan view ofthe stationary shelf and supporting member.

Fig. 2, isa top plan view of the rotary- Serial 310,190,605.

shown as supported in a stove oven with the rotary shelfmember disposed so as to support cooking, roastingor' baking utenand 5, so that the stationary shelf and supporting member can be used for supporting cooking utensils instead of the rotary shelf member.

Fig. 7', is a detail in sectional elevation of the pivotconnection between the two shelf members.

In the drawings, the reference numeral 1 designatesthe side walls of astove oven which are provided with the usual rest mem bers 2 to support an oven shelf.

In carrying out the aim of our invention, we employ a combined stationary and rotatable stoveovenshelf designated 3. which em bo dies the features of our invention. The

stationary shelf section comprises a rectangular frame member t having the ring member- 5 disposed within the borders of frame member A. A spider is arranged within the borders of the ring member 5 and the rectangular-frame Land consists of a central head portion 6 from which bars 7 extend to L the ringmember 5 and then continued from the rlng member 5 by theextensions 8 tothe four sides of the frame 4. Spider bars 9 7 also extend from the ring frame member 5 to the four corners of the frame member 4:. This arrangement provides an efficient stationary grate like shelf for supporting'various kinds of baking "utensils in the usual manner within a stove oven, as will be apparent in Fig. 6. The spider bars 7- carry an endless supporting ring 10 which extends upwardlyabove the upper plane of the

spider bars

7, 8 and f the stationary shelf section to act as a balancing support for the rotary shelf section hereinafter described.

The rotary shelf section comprises an outer ring frame member 11, which is of less diameter than the stationary rectangular frame member 4, shown in Figures 3, 4, 5 and 6,

and a smaller concentrically arranged ring member 12 disposed within the border of the outer ring member 11. A spider is arranged within the border of the inner ring mem er 12 and consists of a central head portion 13 from which bars 14; extend to the inner ring members 12 and then continued from the inner ring member 12 by the extensions 15 to the outer ring member-11. Spider bars 16 also extend radially from theinner ring member 12 to the outer ring member 11 to provide in connection with the

bars

14 and 15, a grate surface.

The rotary shelf section is mounted upon the bearing ring of the stationary square shelf section and the two sections are connected by means of a loosely fitted pivot pin 17, which passes upwardly through an opening 18 in the head portion 6 of the square shelf sectionand then passes upwardly through an opening 19 in the head portion 18 0f the-circular rotary shelf section and which acts as a pivotfor the rotary shelf section to revolve around as well as maintaining the properrelation between the two shelfsections. The-lower end-of the pivot pin..17 is provided with a head 20 which is receivable in a recess 21 in the head portion Bofrtlie squareshelf section and the upper end of .the pi-vot pin 17 isprovided with a head 22 which is receivable in a recess 22 in thehead portion 13 oftheirotary shelf section, as. clearly shownin Fig. 7. The heads. of the. pin. 17 prevent displacement of the pin which assisted by the supporting ring. 10 prevent; wabbling oritilting movement'ofthe rotary. shelf sectionuponthe supporting ring 10. of the stationary square shelf section. The supporting ring 10 is preferably disposed inwardly of the midwaypointv between the .pivot pin. 19 and the rectangular frame membert as it offers little frictionto the rotary member at this pointallowing therotary shelf section .tobe more easily revolved than when it is positioned further outward.

The upper face of the outer ring member llaof therotary shelf is provided with a suitable recess23 between each spider bar 16 thereofso. that the rotary shelf maybe readily revolved. by the operator, either by the fingers of the. operator, on by a convenient tool.

In Figures 4 and 5,. thestationaryshelf section is shown as supported upon therests 2 in reversed relation to that shown in Fig.

6,. whereby the'rotary shelf section is pos1-' tioned above the stationary shelf sect-ion for supportingthe.utensils instead of the stationary shelf section, as illustrated in.Fig..6.

From the foregoing description, itis evi-' dentthat we.have designed a shelf for use injordinary gas or other stoveovens, a shelf that maybe quickly placed in the oven, and effectually serve as a rotary shelf, when installed as .shownin Fig. 5, thereby enabling thecook to revolve the circularshelf to bring the utensils to. the convenient reachv of the cook, so asto prevent burning of the cooks hands, and more important to enable the utensils to be moved with the shelf to various parts of the oven to' receive the desired heat in order thatv the different sides of the differrotary shelf section for supporting utensils when cooking or baking, the shelf may be 'O reversed fromjthe installation shown in Fig. 5, to that shown in Fig. 6, which will pro-. videa stationary shelf for supporting the utensils instead of a rotary shelf, as shown in Fig. 5. When the shelf is installed in an oven, as-shown-in Fig. 6, th'e stationary-shelf section. isthe upper or supporting shelf while the rotary shelf section is disposed below said shelf section and of no service at all. not even as asupporting member, but whenit isinstalled as shownin Fig. 5, the rotary shelf section becomes-a support for the utensils-and the stationary shelfgsection merelybecomes a support-forthe-rotary shelf section. I

The many advantages-- of the herein described invention will readily suggestthemselves to those skilled in the art to" which it y appertains.

From-the foregoing description, itis evi-I dent'that a simple-devicefor-this purpose has-been disclosed, but it is to be understood that we do not desire to-restrict, or limitourselves to. the very details-ofthe construction shown and described, which is merely illustrative, it being obvious that changes, not involving the exercise of invention, may be made without conflicting or departing from v the spirit of the invention within the scope; of the appended claims. I
