Abstract

258,730. Veritys, Ltd. and Lanz, A. Sept. 17, 1925. Mounting: fan apparatus.- An electric ceiling-fan is carried by a hollow pendant shaft a receiving the motor 'leads e, f and connected coaxially to a shaft d which supports the stator g at its lower end. The stator is formed as a cylinder surrounding a tube m mounted on the shaft d and extended at its upper end to form the rotor. The rotor carries fan blades n and is completed by a cover q. The stator core k and coils l are placed opposite the rotor core o and coils o<2>. The tube m rests on a step bearing h lubricated by oil in the space between the stator g and tube m. Passages w in the tube m lead to spiral grooves r on the shaft d and to a chamber r' having outlets r<3>. A lubricant funnel s is reached through an aperture s<2> in a cap c serving to connect the shafts a, d.
