353,996. Cooking by the waste heat of internal-combustion engines. DAVEY, W. L., 678, Elizabeth Street, Melbourne, Australia. June 7, 1930, No. 17730. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 3, 1930.] [Class 28 (i).] The heat of the exhaust gases of a motor car engine is utilized for cooking or heating. liquids, the exhaust manifold being formed with heat - conducting ex tensions arranged to form the walls of, or a support for, a receptacle within which the cooking is effected. As shown in Figs. 2 and 3, a detachable receptacle is used which may be divided by a vertical partition into a boiler having a filling opening, and an oven having a removable door. In Fig. 2, the extensions 31, 32 of the exhaust manifold 6 are solid whereby the receptacle 2 is heated by conduction only. In Fig. 3, the extensions are hollow to permit the exhaust gases to heat the sides of the receptacle 2. The recess 38 is engaged by a tongue on the front upstanding wall extension of the manifold, and a similar recess is provided at the rear of the receptacle. The receptacle is clamped to the side walls by a set-screw and a draw-off tap for the boiler is accommodated in a slot in one of the walls. A space 37, which may be filled with insulating material, may be left between the walls 32 and the cooking vessel. The Specification as open to inspection under Sect. 91 (3) (a) states also that a combined water heater 2 and oven 3, Fig. 3 (Cancelled), is secured by a strap 14 to the exhaust manifold 6, the bottom being grooved to fit over the pipe. The food container 21 is similarly grooved to fit the bottom of the oven and is pressed down by a spring interposed between the lid and the oven door 8. The filler cap 9 is vented, and a drain plug 12 is provided. This subject-matter does not appear in the Specification as accepted.
