Abstract
26,130. Heenan, H. Nov. 19. Fans.-Centrifugal fans are provided with one or more inner casings or plates which can be moved relatively to the impeller and outer casing so as to regulate the volume of air passing through the fan. The fan A, Fig. 1, and casing B are of ordinary construction. A single inner casing D, actuated by serrated rollers E or other suitable means, is mounted between guide-studs d, pulleys, &c. As shown, the inner casing is in one of the extreme positions. The dotted line indicates the other extreme position. In the modification shown in Fig. 5, the plates D are slidably connected together. Each section is provided with an adjusting-screw G. The inner plates may be mounted in any suitable manner and actuated by any suitable mechanism, such as a lazy-tongs arrangement of levers. In this modification, the outer casing B may be dispensed with.
