Abstract

229,322. M³hlstock, A. Feb. 12, 1924, [Convention date]. Window-shutters; electric window opening and closing apparatus.-Folding shutters are automatically opened and closed at predetermined times by screw and nut gearing 6, 4 operated by an electric motor having an adjustable timeswitch 39 and pole-switches 34, 35 in the circuit. The pole-switches 47 and 49, or 48 and 50, are operated by the closing of the circuits 52, 43, 44, 39, 40 or 41, 34 or 35, 51, by means of the hand 39 of the time switch. The motor is driven in the direction for opening or closing the shutter thereby until a stop 16 on the shutter opens one of the switches 17, 19 in the fully-opened or fully-closed positions. A shunt circuit 38 from the time switch continues to energize the pole switches should the time switch break contacts 40 or 41 before the movement of the shutter was completed. A switch 42, adapted for hand operation, is placed in the circuit, the contacts 45, 46 replacing 40 and 41 respectively. The operating screws are left- and right-hand thread respectively and are driven by gearing 9, 10, 12 from the shaft 13, a friction clutch comprising two discs embraced by a common adjustable friction collar being incorporated. Two steel bands 21, 22 are attached to the shutter to cover the slits in the housings of the operating screws. The bands are wound on spring-controlled drums 23, 24. The nuts are provided with inserted parts 33, Fig. 5, which act as cutting tools to clean the thread 5.
