Abstract
891,576. Centrifugal blowers. GENERAL MOTORS CORPORATION. June 21, 1960 [July 6, 1959], No. 21680/60. Class 110 (1). [Also in Group XIII] A reversible blower 220 used in a refrigerating system (see Group XIII) is driven by a reversible motor and includes an impeller 222 having radial blades 224 inclined at an angle of 45 degrees and terminating in a solid rim 226 having its inner surface 228 curving to the left and having apertures 230 therein extending diagonally upward at the right. When the blower shaft 236 rotates with the nearest portion of the rim 226 moving upwardly, air drawn into the inlet 234 is discharged through an outlet duct 238. When rotation is reversed the blower ceases to discharge through the duct 238 and instead discharges through an outlet duct 263.
