Abstract

299,526. Adamcikas, M., (known as Adamtchik, and Massera, G. April 28, 1927. Divided on 303,452. Casings; deflectors. -A rotary fan 68 on a shaft supported in ball-bearings 75 and a thrust bearing 76, operates in a casing 70 which increases in diameter from one side to the other. A fairing 69 is supported in an axial position by arms 71 and has an external contour forming a continuous curve similar to that of the internal contour of the casing 70. The fairing may form part of the fan hub and it may be conical as shown in Fig. 1, or it may be be shaped as shown in Fig. 4, or it may have a parabolic contour. The shaft mav be horizontal or vertical and the fan blades may increase in width from the tip to the hub. Either the large end or the small end of the casing may be the suction end of the fan and a bell 70<1> may be used on the suction side.
