Title: Improvements relating to lifts, hoists and the like
IPC: B66B11/04
Filed: 1922-11-27
Abstract: 206,380. Waygood-Otis, Ltd., and Simmons, T. H. J. Nov. 27, 1022. Electric push-button systems.-To obtain a reduced speed for a lift, hoist, or the like when approaching a selected floor or other desired stopping-place, without employing more than one motor, a supplementary reducing-gear is provided, which is locked normally to give a solid drive, but which can be unlocked automatically at the controlling point. Thus in the illustrated construction, the motor shaft a carrying the planet pinions o, o<1> can be locked by means of the clutch c to the brake drum f integral with the sun-wheal k and thus provide a solid drive to the shaft q connected by worm gearing to the lift drum, or alternatively, the clutch can be withdrawn by the anergization of a magnet u while the drum f is braked by the de-energization of a magnet i, the planet wheels then rotating round the stationary sun-wheel to give a reduced' transmission. By cutting off current from the motor and reengaging the clutch c while the drum f is braked, a powerful braking action is obtained to effect the final stoppage. The control of the two magnets is effected by means of tappet arms engaged with ramps or strikers in the lift well, arrangements being made to render these devices inoperative at any floor at which it is not desired to stop. Specificatioias 107,356, 108,274 and 155,484 are referred to.

Abstract: 522,419. Electric remote control systems. WOOLNOUGH, G. L., SMITH, R. M. A., PRICE, D. R., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 8, 1938, Nos. 32450/38 and 4476/39. [Class 40 (i)] In a system of centralized control of apparatus over the supply network in which an operation is performed in response to at least two ripple frequencies, the receivers comprise a resonance relay having a number of tuned reeds and a common energizing winding, the operating circuit for a desired piece of apparatus being completed over contacts controlled by at least two reeds tuned to the transmitted frequencies. The resonance relay may be constructed as described in Specification 517,971, [Group XXXVII]. As shown in Fig. 1 the closing and opening coils 1, 2 of a main lighting switch having two stable positions are normally shunted by contacts 4-6 and 7-9 of differently tuned reeds of two resonance relays (not shown) or the contacts may all be controlled by a common energizing winding, but the coils may be in series with normally open contacts. In the modification shown in Fig. 3, heating windings 17, 18 of a thermal switch 20 are controlled by normally closed shunt contacts of tuned reeds 22, 24 in which case the frequencies need not be transmitted simultaneously provided that the second frequency is transmitted before the heating effect of the first has diminished. In a further modification, Fig. 4, both operating coils, 1, 2 are shunted by contact 27 controlled by a common frequency, and each coil is shunted by a contact 25, 26 controlled by an individual frequency. The normally opened series contact arrangement and combinations of the series and shunt contact arrangements also may be used in systems where one control frequency is common to two operations. The controlled switch may be operated by a Ferraris motor.
