Abstract

499,691. Ventilators. CHATSWORTH INVESTMENTS PROPRIETARY, Ltd. Feb. 25, 1938, No. 6052. Convention date, Feb. 25, 1937. [Class 137] A ventilator for cupboards and other confined spaces comprises a short split tubular member having a peripheral flange b and longitudinal cuts c forming flexible fingers d with outwardly bent ends e which grip the sides of a hole h into which the ventilator is inserted. The flange b or a separate ring is folded over to grip a disc of fine wire mesh f. Alternatively, the disc f may be secured by a ring of moulded plastic material. In other forms, the ends of the fingers d may be doubled back, or bent inwards, or tongues may be pressed out from the tubular part of the ventilator to engage the sides of the hole and prevent withdrawal. In another form the flexible fingers pass right through the hole and are bent over to retain the device. The ventilator may be made of rectangular shape. The Specification as open to inspection under Sect. 91 describes also a construction in which the tubular member is not split, and another construction in which the device is moulded from rubber, in the latter case with longitudinal grooves. This subject-matter does not appear in the Specification as accepted.
