Abstract

482,032. Centrifugal fans. STURTEVANT CO., B. F. July 28, 1937, No. 20923. Convention date, July 31, 1936. [Class 110 (i)] In a centrifugal fan of the vane-control type, as described in Specification 358,154, with simultaneously adjustable vanes in a converging inlet, each vane support 18, Fig. 3, has a crank 46 with a member 48 received in grooves 44 in a rotary actuator 42, the parts 18, 48 having axes intersecting in the axis of the actuator 42. The member 48 may be cylindrical as shown or conical, Fig. 8, and in this case the member 42 is spherical having its centre lying with the apex of the cone at the intersection of the axes. The actuator 42 consists of a ring with bevel teeth in mesh with a bevel wheel 58 on the control shaft 60. Each support 18 consists of a sleeve surrounding a fixed rod 20 and provided at each end with bushings 40. To prevent entry of dust and dirt to the operating mechanism, the hub 22 is curved at 50 and receives a cover 54, the hub and cover having semicircular recesses for the sleeves 18 and packing 58<1>. A cap 66 is bolted to the hub and secures the bushing 62 for the shaft 60.
