Abstract

423,235. Brakes. INVENTIO SOC. ANON., Hergiswil, Nidwalden, Switzerland. April 25, 1933, No. 12107. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 25, 1933]. [Class 103 (i)] A brake for a lift which avoids violent braking, comprises a brake drum c connected with the motor shaft by means of a friction coupling comprising centrifugal friction blocks e and springs f. The brake comprises shoes a applied by springs and released by a wedge k, operated by a magnet l. At high speed the drum rotates with the motor shaft by reason of the centrifugal blocks e. At low speed the blocks e slip on the drum which is held stationary by the shoes a.
