Title: Improvements in and relating to Electrically Operated Mechanism suitable for Driving Clockwork-trains or the like.
Inventor: HOLDEN FRANK
IPC: G04C3/06
Filed: 1917-08-24
Abstract: 118,329. Holden, F. Aug. 24, 1917. Electric clocks. - Electro - magnetic apparatus for driving a clockwork train &c. comprises a spindle a mounted in top and bottom pivots and normally biassed by a spring t for the parts to occupy the position shown in Fig. 1. A three-armed spider g is mounted on the spindle a, two of the arms carrying balance weights k, while the third arm carries a coil h adapted to encircle the upper ring of a permanent magnet c, The magnet comprises two rings joined together by a paramagnetic block d; the upper ring is divided and is provided with pole-pieces e of the same polarity. The lower ring may carry a paramagnetic block f. A switch for the coil h comprises a fixed contact q, attached to an adjustable plate r, and a movable contact o which may turn round a pin m fixed to, but insulated from, an arm l on the spindle a. The turning movement of the contact o is restrained by a spring p. One end of the coil h is joined to the contact o and the other end to the frame; the terminals of a battery v are connected to the plate r and frame respectively. The apparatus is started by twisting the spindle a in a clockwise direction until contact o is at the left hand side of the contact q, and then releasing it, the retum movement caused by the spring t causing a relatively long engagement of the contacts o, q, thus energizing the coil h from the battery, and imparting a counter-clockwise impulse to the spindle a. The spring gradually brings the spindle to rest and then reverses its movement. When the spindle is moving in the clockwise direction the contacts o, q are in engagement for so short a time that no appreciable current passes through the coil. The oscillatory movement of the spindle may be utilized to drive a train of wheels &c. by means of a pawl and a ratchet wheel &c. The spring t may be adjustable like the hair spring of a watch or clock. Another construction of switch is shown in Figs. 5 and 6. The pin m is bent upwardly to form a stop m<1> for the contact o; the contact q is pivoted on a pin 5 fixed to the adjustable plate r, and is held by a spring 6 against a fixed stop 7. The upper and lower rings of the magnet c may be cut through and the ends bent at right angles to form pole-pieces, :
