Patent GB-255891-A (GB)
Title: Improvements in or relating to striking mechanism for clocks
IPC: G04C21/10
Filed: 1926-07-22
Abstract: 255,891. Gernaert, J. July 22, 1925, [Conventiondate]. Striking-mechanism.-Once in each revolution a projection on a wheel 15, Fig. 1, geared to the minute wheel 12 raises a lug 34 on a lever 35 pivoted at 36 so that when 'the lever 35 returns downwards a pawl 37 thereon slightly advances a notched wheel 38, Figs. 1 and 3. This wheel 38 is rigid with wheels 40 and 41. Wheel 40 coacts with a lug 44 or a blade 45 to close contacts 47, 48 in the circuit of the striking mechanism; this wheel has twelve sets of teeth corresponding to the hours. A pawl 53 reciprocated by a rod 2, which is oscillated by the pendulum 1, coacts with twelve sets of teeth on the last wheel 41 there being a space, between each two sets of teeth. When, therefore, the pawl 37 slightly advances the wheel 38 the first tooth of the next set on the wheel 41 is brought into engaging position with the pawl 53. Thereafter the rod 2 and pawl 53 rotate the three wheels as many steps as there are teeth in the set. At the same time the appropriate set of teeth on the wheel 40 depresses the lug 44 and closes the contacts 47, 48 a number of times corresponding to the hour. In a preferred construction of striking mechanism 'the magnet, the circuit of which contains the contacts 47, 48, acts as a relay for a second and stronger magnet which operates the bell hammer. Electric clocks.-The Specification as open to inspection under Sect. 91 (3) (a) describes also an electric clock in which, when the amplitude of the pendulum 1 falls below a certain predetermined limit, a freely swinging rod on a member oscillating with the pendulum closes contacts, thus energizing an electromagnet of which the armature gives an impulse to the pendulum. The pendulum 1, Fig. 1 and Fig. 4 (Cancelled), has a slot 3 oscillating a rod 2 rigid with an arm 6 carrying a pawl 7, which thus moves a wheel 8 of sixty teeth one tooth per second. The spindle 9 of the wheel 8 carries the seconds hand centrally of the dial and also carries a lug 11 which moves the minutes wheel 12 one tooth per minute. For accuracy the wheels 8 and 12 are aligned by rollers attached to spring blades. Freely suspended at 28 to the rod 2 is an arm 27 which, in oscillating, lags a little behind the rod 2. Normally this arm 27 wipes over a notched member 29 on a blade 30 but when the amplitude of the pendulum's swing diminishes the arm 27 fails to clear the member 29 and, on the return of the rod 2, this arm 27 is forced back out of the notch thereby depressing the blade 30 to close contacts 32, 33 in the circuit of a magnet 21. On attraction of the armature 23 the cranked end 23 of a rod 25 rigid with this armature gives an impulse to the pendulum. The apparatus may also be used as a master clock sending minute impulses to secondary clocks. For this the arbor 9, rotating once per minute, carries a contact arm 71 co-acting with a second contact arm 70 rigid with the pawl 7, Fig. 4 (Cancelled). This subject-matter does not appear in the Specification as accepted.
