354,263. Oven doors. MAXIM SOC. ANON. FABRIQUE D'APPAREILS THERMO-ELECTRIQUES and HOFER, H., Buchserstrasse, both in Aarau, Switzerland. May 6, 1930, No. 13927. Convention date, April 1. [Class 126.] A door particularly for baking ovens, in which the mechanical strain is taken by a supporting member carrying the hinges and disposed between two cover plates has the supporting member formed of two stiff metal strips 5 extending from the lower corners to the upper middle of the covering plates 1, 2 where they are joined by a handle plate 9 having shanks 9a which pass through slots in the outer cover plate 2. As shown applied to a horizontally pivoted door for an electric baking oven, adapted to support the cooking vessels when open, the two dished enamelled cover-plates 1, 2 are connected together by screws 4 at the corners so as to grip between them the supporting member comprising two steel strips 5 with reinforcing ribs 5a. The lower ends of the strips 5 are each provided with a hinge portion 6 engaging pins 7 on the frying box B, and a stop segment 8 connected to the strips supports the door in the open position. The bent up shanks 9a support the operating handle which comprises two levers 10 pivoted on the shanks 9a and carrying at their outer ends the handle 10a and at their inner ends a roller 10b adapted to take behind a lock plate 11. Between the two strips 5 a ventilating device V passes through the door. The cover-plates may be slightly embossed to provide increased rigidity.
