Title: Bell ringing device
IPC: G10K1/34
Filed: 1921-12-02
Abstract: 172,314. Gubler, E. Doc. 3, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. B e l l - operating mechanism, electric a n d mechanical; bells, silencing. - A bell rope is pulled down an adjustable distance by a pulley over which it is led, the pulley being intermittingly clutched to a continuously revolving shaft by electric or mechanical means controlled by the rope. In the form shown in Fig. 1, the bell-rope 3 passes over a pulley 29 and terminates in a weight 109. The pulley 29 is clutched to the continuously revolving shaft 113, during each downward motion of the rope, by an electromagnetic clutch 110 of the belt-tightening type, operated by a switch device carried by the rope. The switch device comprises a cylinder composed of ends 4, 6 of insulating material and a middle portion 5 of conducting material, together with a sleeve sliding on the cylinder and composed of conducting halves 23, 24, which are insulated from one another at 41. The half-ring 24 carries projecting contacts 9, 10. In order to start the bell ringing, the switch 21 is momentarily closed by hand, so that the clutch-magnet 39 is energized by the battery 22. To maintain the motion, the movable switch-contact 15 is set upon the lefthand contact 14, so that the circuit through the battery 22 and clutch-magnet 39 is closed during the downward movement of the rope through the ring 23, conductor 5 which slides through the rings, ring 24, and contacts 10, 8, the length of the period of closure being determined by adjusting the length of the conductor 5. During the upward motion of the rope, the circuit is broken, owing to the contact 9 on the ring 23, 24 being drawn up, by friction, against the dead contact 7. To stop the bell quickly, the movable switch contact 15 is set upon the contact 13, so that a downward pull is given to the rope during its upward motion, shock being taken up by slipping of the rope and belt In a modification, a doubleacting apparatus is provided comprising two ropeswhich are pulled alternately. Instead of a belttightening clutch 110, a belt with fast and loose pulleys or a cone friction clutch may be employed. The clutch magnet 39 may be normally energized or normally de-energized; or the clutch may be controlled by the rope through purely mechanical means.
