We next come to the space in which the main bearing islocated. The base is the turbine ball bearing sleeve 32,which is pressed upon the shaft and is prevented fromturning by the drive pin 33. The rotating raceway 34 isheld in place against a shoulder on the sleeve by a nut 35,screwed upon the latter. The stationary raceway 36, isheld by a ring 37, supported by the brackets 38, which areintegral with the casing of the machine. The raceway isheld in place by the bearing cap 39, which is a ringfastened to the ring 37, by tap bolts. The sleeve bears against a shoulder on the shaft andbeyond it there is a collar 40 which rotates with the shaftand carries a series of vanes, not shown in the engraving,by which the ventilation of the armature is vanes produce a current of air flowing from left toright through the armature and discharging into the space. Valve for Pyle-National Turbo-Generator containing the ball bearing, from which it escapes intothe atmosphere through a hole in the casing of the ma-chine. At this point the casing is again split, the central por-tion or generator yoke 41, being held to the turbine casing42, by a row of tap bolts 43. The generator yoke contains the armature, field mag-nets and coils, the coil collar also extending through itand being held in place by the armature shaft nut 50. The laminations 51, of the pole piece are held togetherby pole pins 44, which are turned cylindrical from end toend with a shallow countersink at each end. After the pin has been put in place and the pole endpieces 45, slipped over the ends, the pin is riveted overthus firmly binding the laminations together. They are alsostill further held by pins 46, which are run through theend pieces and laminations and riveted at the ends
