Abstract

214,935. British Thomson-Houston Co., Ltd., and Taylor, H. W. Oct. 24, 1922. Casings, foundations, and supports; cooling.- In a closed-circuit air system for cooling and' ventilating a dynamo, the air is admitted through apertures formed in the bottom of the machine casing in addition to being admitted at the ends of the casing. It may be discharged through apertures placed between the first named apertures into ducts situated in the foundations of the machine. The left and right-hand sides of Fig. 2 show cross-sections respectively on the planes X X, Y Y of a machine shown in longitudinal section on Fig. 1. The casing 1 has apertures 3<a> coinciding with openings in the base plate 3 from which the air passes through openings 3b and ducts 4 in the foundations to a chamber 7 beneath the machine containing the coolers 8. Air is admitted to the casing 1 at each end and through alternate apertures 5 in the bottom of the machine. It is discharged from the intermediate compartments 6 to the ducts 4 indicated by the arrows. Fans 9 are provided at points where the air passes from the ducts 4 into the chamber 7, or, alternatively, the fans may be placed between the coolers and the underside of the dynamo. Specification 165,957 is referred to.
