Title: Improvements in and relating to clock mechanisms
IPC: G04C3/02
Filed: 1942-01-21
Abstract: 554,450. Electric clocks. TELEPHONE MANUFACTURIN.G CO., Ltd., SMITH, S. J., and TERRY, R. S. G. Jan. 21, 1942, No. 873. [Class 139] A pendulum-opetated and controlled clock mechanism of the kind using a free pendulum 1 which receives energising impulses from a falling gravity arm 7 at equal intervals of time, under the control of an attendant pendulum 48 which may form part of a master clock, is characterised in that the gravity arm 7 is adapted to be raised into a position offering no obstruction to the swing of the pendulum 1, by a lever 14 rocking about a fixed fulcrum 15 and mechanically biased into a position supporting the gravity arm, and electrical means are provided for rocking said lever to release the gravity arm, which then becomes free to fall and impulse the free pendulum. In the embodiment shown in Fig. 1, electromagnet 19 is periodically (say at every half-minute) energised under the control of an attendant pendulum as described in Specification 545,910, and lever 14 is rocked counterclockwise against the action of spring 16, adjustable as to tension by nut 27 and as to leverage by notches 25. Gravity arm 7, the effective weight of which is adjustable by screw 13 falls, and its freely rotatable sector-shaped striker 9 comes into rolling contact with pallet 4, Figs. 2-5 (not shown) to impulse pendulum 1, and in its lowest position arm 7 releases latch 20 to free lever 14 which rises again under spring action. Arm 29 depending from lever 14 carries a pin 30 which steps on ratchet wheel 31 at each up-and-down movement, wheel 31 momentarily closing contacts 28 at each movement, to send a synchronising impulse to the attendant pendulum in the manner described in the aforesaid Specification. Wheel 31 also drives flywheel 37 which has two stop pins 38 co-operating with the end of rod 39 secured to lever 14 so that a complete number of half-revolutions of wheel 37 takes place for each step of movement of wheel 31. In a modification, Figs. 8, 9 (not shown), gravity arm 7 carries a pallet and pendulum 1 carries a sector shaped roller maintained in inverted position by an adjustable counterweight. If the current to electromagnet 19 should fail, gravity arm 7 remains in raised position clear of pendulum 1, while if magnet 19 should remain energised, arm 7 remains in its lowest position, where also it forms no obstruction, Figs. 5 and 7 (not shown), In the embodiment shown in Fig. 10, arm 49 on the attendant pendulum 48 closes contacts 50 at half-minute intervals to energise magnet 19 through normally closed contacts 60. Magnet 19 locks up by rocking lever 14 to close contacts 58. When arm 7, released by lever 14, has fallen to its fullest extent, its arm 22 closes contacts 57 to energise magnet 55 which corrects the attendant pendulum in the manner described in Specification 545,910. At the same time, lever 56 opens contacts 60 to de-energise magnet 19 to release lever 14 which restores arm 7.
