Title: Time piece with audible alarm
IPC: G04B23/06
Filed: 1939-06-09
Abstract: 589,122. Alarm clocks. GOLDBERG, S., and BAUER, A. H. June 9, 1939, No. 17012. Convention date, June 11, 1938. [Class 139] An alarm clock of the type in which the alarm release mechanism is operated by co-operation between manually positioned stops arranged round the dial and a rotary arm fixed to the hour arbor is characterised by the particular arrangement of the stops and release movement and by the provision of novel means for limiting the duration of the alarm and automatically returning a stop to its normal position after each release. In the embodiment described the alarm can be operated at any quarter of an hour since there are forty-eight non-rotatable stops 22, Fig. 5, arranged equidistantly around the dial. These stops may be independently held in an inclined operative position, against the action of a return spring 28, by the engagement of a notch 27 with a ring 25 inside the casing. When in this position the inner end of the stop projects into the path of rotation of an arm 29, Figs. 2 and 5, fixed to the hour arbor and carrying the release lever 30 pivoted at 33 and forked at its inner end to engage a pin 36 on a disc 39 carried by a sleeve 37 on the hour wheel spindle. the lever 30, on contacting any stop 22 which is in the operative position swings about its pivot and imparts a relative rotary movement to the sleeve 37 carrying discs 39 and 40, said relative rotary movement producing an axial movement of the sleeve towards the wheel 31 by virtue of the engagement between an inclined slot 41 in the sleeve 37 and a stud 42 fixed to the bush of the wheel 31, Figs. 6 and 7. The detent 15 of the alarm movement, which is normally held stationary by the flange 40, is thus released and the hammer 14 strikes the bell 13, Figs. 4 and 5. The duration of the audible alarm is limited to the time taken for a single revolution of a wheel 18 in the alarm movement, Fig. 4, the alarm stopping when the wheel 18 is arrested by means of a pin 19 thereon engaging the upper cranked end of a lever 20 the lower cranked end of which engages a four-nosed cam 43 carried by the minutes arbor. The wheel 18 is freed for the next release of the arm mechanism by the lower end of lever 20 dropping to the bottom of a nose of the cam 43 under the action of a spring 44. In the meantime, a sloped nose 32, Fig. 2, of the arm 29 engages the stop 22 and forces it up whereupon it is returned to its out of action position by a spring 27, Fig. 5. The sleeve 27 is now moved back to its initial position by the spring 34 acting on the lever 30 and the alarm is stopped again by the disc 40 arresting the detent 15. The alarm mechanism is now ready to operate when lever 30 meets the next stop 22.
