Abstract

919,794. Ventilators. SOLEM, T. Dec. 4, 1961, No. 43336/61. Class 137. [Also in Group XXVI] In a ventilation fan arrangement comprising an open-ended housing in which is mounted a motor 4 for driving fan blades 5, a cover or damper 6 is spring-urged into the position in which it closes one end of the housing and is opened and closed under control of cam means 13, 14 which also control the operation of a switch 16 for the motor. As shown, cam pieces 13 are fixed to the inner surface of a sleeve 7 rotatably mounted in the end 4<SP>1</SP> of the motor and engage similar pieces fixed to the cover which is urged towards the left by springs 12 on guide rods 11. An outer ring 9, guided in an annular groove 10, is fixed to the sleeve by radial arms 8, and the ring and sleeve are rotated by a line (not shown) attached to the ring. A quarter revolution moves the cover from the fully open to the closed position or vice versa, and the switch 16 is actuated by arms 8 to switch the fan motor on and off accordingly.
