Abstract
595,415. Porthole ventilators. BURGESS, A. F. (ILG Electric Ventilating Co.). Jan. 10, 1945, No. 845. [Class 137] [Also in Groups XXV and XXVI] A porthole ventilator comprises a cylindrical casing 29, mounting a motor driven fan 30 (see Group XXV), and supported by a bracket such that either end of the casing may be fitted in the porthole, and louvres 59 in the casing which allow the ventilator to be used in blackout conditions and stormy weather. As shown in Fig. 6, the edges 33, 34 of the casing are adapted to fit into a rubber gasket 20 on a ring 14 surrounding the porthole opening 11, and the casing is pivotally supported at 44 on a yoke member 41 pivotally mounted on a hinge 53, Figs. 1 'and 3, which is pivoted at 45 to lugs 46 on the ring 14. Locking means 47, 51 and 56 are provided for the three pivotal movements respectively (see Group XXV). In Fig. 3, the ventilator is shown mounted for circulating air in a ship's cabin while the porthole is closed by a conventional lens and cover 17 hinged to the ring 14. The lens sash and ventilator casing are clamped against the gasket 20 by dog bolts 21 pivoted at 22 which co-operate with lugs 19 and 36 respectively. The louvres 59 are concentrically nested tubular members so shaped as to prevent transmission of light through the porthole, and a similar set of auxiliary louvres may be fitted in the porthole opening together with horizontal louvres and a visor, to give additional protection against weather.
