Abstract
408,201. Safety devices for lift cages. MICHELUTTI, G., 2, Rue Tewfick, Alexandria, Egypt. July 1, 1932, No. 18676. Void [Abridged as open to inspection under Sect. 91 of the Acts, Nov. 29, 1933]. [Class 78 (iii).] In a safety device for lift cages wherein bolts 14, 15 on the cage engage rack members 16, 17 in the lift well to stop the cage when the hoisting cable breaks, the bolts are connected to rods 12, 13 provided with pins 8, 9 engaging in slots 6, 7 in a beam 1 supported on a spindle 2. This spindle is secured to the cable and mounted in slots 3<a> in a pair of plates 3 secured to the cage so that when the. cable breaks the beam 1 falls and the rods 12, 13 are pushed outwardly and the bolts pressed into engagement with teeth 16<a>, 17<a> by springs 18, 19. Auxiliary bolts connected by cables to the bolts 14, 15 respectively, simultaneously engage the teeth.
