Abstract

367,478. Electric clocks. TIBBLES, H. J., Brodsworth, Blenheim Crescent, Leigh-on-Sea, and RELY-A-BELL BURGLAR & FIRE ALARM CO., Ltd., 49A, Wilson Street, Finsbury Square, London. Nov. 29, 1930, No. 36004. [Class 139.] The arbor 1 of a clock is extended bevond its rear plate 2 and has fixed in it a ratchet wheel 4 engaged by a pawl 5 on a disc 6 loose on the arbor and acted upon by a driving spring 7. An insulated contact 8 on the disc 6 is adapted to engage an insulated contact 9 on a disc 10 also loose on the arbor. The disc 10 is connected by a link 11 with the pivoted armature 12 of an electromagnet 13. The latter is so connected up with a battery that when the contacts 8, 9 meet, the electromagnet 13 is energized and the armature turned, the link 11 turning the disc 10 and by means of the engaging contacts 9, 8 tensioning the spring 7. Towards the end of the armature movement, one end engages a spring contact lever 19 tripping it and causing the parts to resume the position shown.
