Abstract
742,849. Ventilators. MORELAND, A. S. Dec. 28, 1954 [Oct. 1, 1953], No. 26918/53. Class 137. A ridge roof ventilator comprises a box-like casing formed of a pair of end plates 10 ribbed to facilitate the securing of side walls 13, a hood 17 and deflector strips 18, 41, and a pair of deflector plates 30 which are rotatably mounted beneath the hood 17 and are movable from an open position, indicated in full lines in Fig. 3, and in which air entering the casing through its base is swept out by wind currents entering the sides 32 of the casing, to a closed position, shown in dotted lines, in which they close the side openings 42 of the casing. Each deflector plate 30 is mounted at each end on a quadrant 28 which has a trunnion 27 rotatable on a boss 26 projecting from the respective end plate, linked springs 36, 36 being connected between an operating arm 31 on each quadrant and the respective end plate 10 to load the deflector plate against the final part of its movement in either direction and prevent a hard impact on padded stops 33, 34 secured to the end plates.
