Morton, Mans?eld, Ohio, assignor to Westinghouse Electric Corporation, East Pitts burgh, Pa., a corporation of Pennsylvania Application May 18, 1943, Serial No. 487,440 1 Claim. (Cl. 219-37) 2 1 This invention relates to heating apparatus Fig. 3 is a bottom plan view of the supporting member which carries the controls and wiring for the surface cooking units; and Fig. 4 is a view similar to Fig. 2, illustrating and particularly to an electric cooking range, and it has for an object to provide an improved de vice of the character set forth.

This arrangement has the further ad vantage of facilitating servicing of the range when repair or replacement of the controls or 40 August 11, 1942, and assigned to the assignee of the present invention. Ends I5 of the sheathed Wiring is needed, since the supporting member may be readily removed from the range provid for cleaning by merely swinging the unit up wardly out of the platform, the mentioned con tacts being separated by this movement. Energization of the surface units is controlled by any suitable means, such as switches 22, which ing ready access to all of the wiring and con trols. heating elements are bent outwardly, as shown in Fig. 2, and provided with suitable electrical contacts adapted to detachably engage electrical contacts mounted within a terminal block 2|, supported beneath the platform, when the sur face unit is disposed in operative position in the range platform. It will be understood that each surface unit is readily removable from the range These and other objects are effected by my in are adjusted by means of knobs 23. vention as will be apparent from the following In accordance with my invention, I mount the description and claim taken in connection with switches and the wiring connecting the surface the accompanying drawings, forming a part of units to a source of electricity on a subplatform or this application, in which: Fig. 1 is an exploded view, in perspective, of 50 panel 24 which is placed on the range body after the wiring and switches have been installed on an electric range made in accordance ‘with the the subplatform, thus substantially reducing the present invention and illustrating the manner time required to wire the range on the assembly of assembling the range; conveyor.
