Johnston, Mans?eld, Ohio, assignor to Westinghouse Electric Corporation, East Pittsburgh, Pa., a corporation of Pennsylvania Application January 29, 1944, Serial No. 520,148 2 Claims. (Cl. 68-13) Y 2 My invention relates to clothes washing appa ratus and has for an object to provide improved apparatus of this kind. A further object of the invention is to provide, in a domestic clothes washer having a shelf struc open at its front for the ingress and egress of the fabrics to be treated and the open end of the tub being treated approximate the rated capacity of the machine. The washing operation is ine?l now be had. The switch structure 2| includes a casing 22 is closed by a suitable, gasketed, hinged door H. The tub I0 is enclosed within a casing structure l2 having a front wall, the upper portion 13 of ture upon which the fabrics to be treated are col which is inclined and provided with an opening lected prior to depositing the fabrics in the ma M in registry with the door ll. When the wash chine, an indication to the operator when the ing machine is not in use, the opening I4 is closed weight of the bundle of fabrics upon the shelf ap by hinged door or cover IS.
