To all 'whom t may concern.'

Be it known that I, FRANK F. FoRsHEE, a citizen of the United States, and a resident of Flint, in the county of Genesee and State of Michigan, have invented a new and useful Improvement in Electric Ranges, of which the following'is a specification.

y invention relates to electrically-heated apparatus| and particularly to electric ranges, and it has for one of its objects to provide a unitary electric oven and a unitary electric' stove, which may be so mounted, in interchangeable side-by-side relation on a supporting member, as to make either a leftand or a right-hand range.

A further object of my invention is to provide an electric oven and an electric stove which the Shop without reference to may be shipped individually and may then be assembled on the supporting base to form either a right-hand or a left-hand range, as ma be desired by the purchaser.

eretofore, an electric range was completely assembled at the factory and shipped to the distrlbuter or to the purchaser and it was im ossible to reverse the relative positions o the oven and the stove on the supporting frame.

More specifically considered, my invention embodies a unit-ary electric stove member, a unitary electric oven, reversible electrical connecting means therebetween, and a supporting frame` on which both the oven and the stove may be mounted in interchangeable side-by-side relation.

In the single sheet of drawings, Figure 1 is a view, in front elevation, of an electric range embodying stove and the oven assembled to -form a so-called left-hand range, and Fig. 2 is a view, in front elevation, of the same oven and stove assembled to form a right-hand range.

An electric oven 1 and an electric stove 2 are mounted adjacent to each form 3 which is, in turn, supported by a plurality of supporting members 4. A plurality of control switches 5 and an electromagneticaliy-operated switch 6 are located at the front of the steve 2 and are used to control energy to the various heating elements of the oven and the stove.

The oven `1 is locatedpon the platform 3 between the front and the rear leg support may be completely manufactured at -1 serve to hold the each other,

4in the rear wall of the my invention, with the ya .doubleother on a platbrackets 4a at the outer edge ofthe platform and an angle-iron member 8 suitably secured to the platform 3 at substantially the middle of `its length. Screws 7 through the brackets 4a and a plurality ot, screws 9 through -the vertical side of the member 8 oven in its operative position on the platform 3.

' he stove 2 is secured to the platform 3 by means of a plurality of screws 10 which clamp-aI depending apron 11 at the front of they stove 2 against the platform 3. A.

simllar apronll is provided at the rear of the stove 2.

The upper part of the stove 2 and of the oven 1 are held in proper alinement by means of a shelf back 12, which is provided with ornamental end pieces 13. Screws 14, through the end pieces 18, hold the outer ends of the top of the stove and the oven 1n proper operative engagement with the shelf back. The inner ends of the top of the stove back and of the oven are further held in alinement by means of a small metal strap 15 and screws 16.

An extension shelf 17 is provided for the stove and is detachably secured thereto in anyfwell known manner.

As the controll switch 5 and the electromagnetic switch' 6, which control the heating element (not shown) in the oven 1, `are mounted at the front of the stove 2, suitable electrical conductors are provided to connect the control switches to the heating element in the oven 1. A terminal block 18 is ,provided oven 1, to which a heating element "(not shown) for-the oven may be connected. A. second terminal block 19 is provided, and two conductors (not shown) connect the terminals oi this terminal block to two of the contact terminals of ole switch 20, only the operating which is shown. The other two of the switch 20 are operby means yot conductors e outer terminals on the terminal block 18. A triple conductor cable 2l connects the switch .5 and the circuitbreaker 6 to the terminal blocks 18 and 19 and is located yas follows: beginning at the rear of the switch 5 and the circuit-breaker 6, the cable runs to the rear and Acenter of the stove 2, at whichA point the conductors pass through the rear wall through openings handle ocontact terminals atively connecte (not shown) to t .in an insulating member 22 end then run, in a substantially horizontal position, across' tion, is provided to protect Vthe cable 21 at 'l the horizontal part o its length..

A control circuit, comprising a twin conductor cable 27, extends Jfrom the electromagnetic switch 6 to a third terminal block 28 which is mounted on the rear wall of the oven, and .this control cable Jfollows substantially the same path as does the cable 21. It may be pointed out that the insulating bushing 22 and the terminal blocks 18', 19 and' 28 are located on the center lines of the stove and of the oven, respectively, for a purpose to be hereinafter set forth,

Il it be assumed that the electric range has been completely assembled as a lefthand rangej as shown in Fig. 1, and that vit is desired to reassemble it as a right-hand range, we may proceed as follows.

Remove the terminal covers 23, 24 and 25 and the wire cover 26 from the back of the range and disconnect the wires of the two cables 21 and 27 :trom the Contact terminaison the terminal blocks 18, 19 and 28. Remove the screws 10 from the front and the bach of the stove and remove the stove bolts 14 from the shelf back 12. Remove the stove bolts 16 and the strap 15l and the extension shelf 17. The stove 2 may now be turned through an angle of 180 on a vertical axis, and the screws and stove bolts l0 may then be replaced.' The relatively heavy and stiff cable 2 1 now extends awayirom the oven 1.

New remove the screws 7 rom'the front and the rear ieg-support bracket and also remove the screws 9 which hold one end o' the oven in operative engagement with the member 3. rEhen turn the oven through an angle ol2 180o on a vertical anis and replace the screws 7 and 3.

The cables 21 and 27 may now be bent through an angle of 180 and again connected to the proper Contact terminals on the terminal blocks 18, 19 and 28. As these bloclrs are on the center line of the oven 1, no more than ordinary care need be used in bending the cables 21 and 27 to insure their extending to the contact terminals in the .new sidebyside relation ci the oven and the stove. "7J-She terminal covers 23, 24; and 25 and the wire cover 23 may now be replaced in their proper operative ositions on they bach of the stove and of t e oven.

Replace the shelf nach 12 and the bolts 14 and the strap l and the fbolts 16 and the extension shelf 17 at the outer side of the stove 2.

The oven and the stove are now von reverse ends of the platform 3 and arranged to make a right-hand range, with the front of the complete range on the opposite side of the'platform, and it is only necessary to turn the complete range through an angle of 180o to have its front on the same s1de as before.

I thus provide a unitary oven and stove which may bebuilt individually at the factory, shipped separately and assembled at the purchasers home, thus reducing considerably the expense of packing and of shipping. In case it is desired or becomes necessary to reverse a range, this may be easily and quickly effected. It may also be pointed out that a distributor may order a supply of stoves, ovens and supporting members and may then assemble them to make either aright-hand or a left-hand range, as may be required by the purchaser.

While I have shown a specific embodiment of my invention, various changes may be made without departing from the spirit and scope of my invention, and I desire that only such limitations shall be placed thereon asare imposed by the prior art or are specifically set forth in the appended claims. i

I claim as my invention:
