Abstract

229,012. Riley, A., and Riley, S. Nov. 19, 1923. Air, heating and cooling; forced ventilation; ventilating vehicles.-The interior of a motor vehicle body is ventilated by admitting controlled supplies of hot and cold air to a mixing chamber in front of the instrument board from which air of the required temperature enters the body. In one construction, Fig. 1, the fan A behind the radiator B is enclosed in a compartment C, which communicates by means of a conduit D, which may pass round the exhaust pipe, with a mixing chamber J behind the dashboard Z. The cold air is admitted at E<2> to a chamber E preferably provided with a blower G and communicating by way of a conduit F with the chamber J. Each conduit D, F is provided with a valve G<2> preferably operable from the dashboard or instrument hoard Y. In a modification, the compartment C, Fig. 3, and-cold-air passage E<3> communicate with a mixing chamber K formed by providing a partition K<2> across the bonnet, a double flap-valve L controlling the admission of either hot or cold air. The compartment C also has lateral outlets C<3> provided with shutters which may be interconnected with the valve L. In a further modification, the hot air passes through the upper part only of the radiator B, Fig. 4, and enters the mixing chamber K at N controlled by a flap valve 0, a second flap valve P being provided to prevent the hot air passing over the engine when not so required. The cold air in this construction enters at the aperture M controlled by the valve R.
