Shames, H; Shames, S J

An energy saving vent is provided for selectively directing hot, moist exhaust air from a clothes dryer either through a downstream vent sleeve to the outdoors, or through a vent port to the indoors. The vent includes four major components principally molded from a synthetic plastic resin, the components being: an open sided housing; a closure panel for closing one open side of the housing; a valve member within the housing for selectively directing air through the housing in alternate paths; and a filter screen assembly for another open side of the housing. The selectively swingable valve carries a pressure relief means adapted to provide for passage therepast of pressurized exhaust gas when the valve is in its position to direct air flow indoors, and in the event that the flow of air indoors is blocked by the filter screen being clogged. The preferred filter screen is a truncated, basket-like, member that is carried on a frame which is removably carried in a slide channel defined on the housing. The valve member is formed integral with an elongated pivot shaft. Opposed portions of the housing are formed to provide bearings within which the valve's pivot shaft is selectively pivotable, and axial slidable. Means are provided for latching the valve in each of its alternate positions.
