Abstract

833,112. Alarm clocks. SIERHUIS, P. F. C. Dec 17, 1957 [Dec. 19, 1956], No. 39231/57. Class 139 In an alarm clock the alarm is stopped by depressing the knob 7 to cause the end 9 of the brake lever 8 to arrest the hammer actuating gear 6. At the same time a lever 12 hinged to an extension 10 of the lever 8 is moved so that a pawl extension 13 of the lever 12 engages a tooth of a gear 3 fixed to the centre arbor. As the gear 3 rotates the lever 8, 10 is slowly returned by the spring 16 to free the alarm mechanism. If the clock is held upside down and the knob 7 is depressed the lever 12 falls so that its projection 14 is latched by a fixed detent member 15 and the alarm mechanism is thereby locked until the knob 7 is again depressed or until the alarm spring is wound.
