Definitions

  • TIMEPIECE ALARM MECHANISM Filed Oct. 20, 1964 2 Sheets-Sheet 1 July 19, 1966 P- M. TUREL TIMEPIEGE ALARM MECHANISM 2 Sheets-Sheet 2 Filed Oct. 20, 1964 3 G v F.
  • FIGA A first figure.
  • Alarm clocks of a conventional type include alarm mechanisms adapted to repeat the alarm signal every morning, provided the user has previously rewound the driving spring and has released the alarm mechanism.
  • the winding of the spring releases the bell so as to cut out one of the daily operations required for the setting of the alarm.
  • the present invention has for its object an alarm time-piece of the type including a knob through which it is possible to manually interrupt the ringing of the alarm while a mechanism provided with an alarm lever adapted to be shifted transversely with reference to the plane of the movement under the action of the alarm wheel and of the hour wheel limits to a predetermined angle the rotation of the alarm barrel.
  • the knob provided for cutting off the ringing of the alarm produces the rotation of a yoke rocking in a plane parallel with that of the movement so as to engage the alarm lever which stops the hammer and holds said yoke fast until the hour wheel raises in its turn said alarm lever whereupon a spring returns the rocking yoke and the handoperable knob (stopping the movement of the alarm) into their initial positions.
  • FIGS. 1 and 2 are respectively a plan view and a sectional view through line IIII of FIG. 1 of the arrangement in its inoperative position, while FIGS. 3 and 4 are corresponding views showing it when operative.
  • a mechanism limits to a predetermined number of revolutions the rotary movement of the alarm barrel as provided by the stop wheel 9 acting on the alarm lever 13 which holds the alarm hammer 20 fast.
  • a hand-operable knob 29 allows stopping the ringing of the alarm.
  • the axial shifting of the hour wheel 5 produces each time the alarm has rung and each time said ringing has been cut off by hand, a shifting of the alarm lever 13 which allows the different parts to return to their starting positions under the action of the return springs 12 and 33.
  • the alarm mechanism includes a spindle 1 of which the end extending-through the bottom of the time-piece is provided with a time setting knob 2.
  • a spindle 1 of which the end extending-through the bottom of the time-piece is provided with a time setting knob 2.
  • the web of which is provided with two notches 4 are loosely fitted the hour wheel 5 carrying two projections 6.
  • the alarm-controlling wheel 7 is provided with an arcuate opening 8 and forms a sector of an annulus coaxial with the spindle 1 and a stop wheel 9 carrying on ice its lower surface a cylindrical pin 10 and on its upper surface a conical stud 11.
  • the spring 12 extends across the path of the pin 10.
  • the alarm-releasing lever 13 terminating with the tail-piece 19 is pivotally secured to a screw 14 provided with a bearing surface engaging a pillar 15 of the timepiece movement, said lever engaging the upper surface of the hour wheel 5 under the action of a blade spring 16 fitted under the bridge 17 of said movement.
  • An angle bar 18 rivetted to the lever 13 includes a horizontal section located above the path of a conical stud 11.
  • the alarm hammer 20 is adapted to rock in the plane of the movement and carries on one surface a spring 21 secured by a screw 22 while its outer end 23 is folded at right angles.
  • a yoke 25 pivoting round the pillar 15 carries on its upper surface a conical stud 26 and also a cylindrical pin 27 engaged by the shank 28 forming a coaxial extension of the pusher knob 29 which cuts off the ringing of the alarm;
  • a wheel 30 meshes, on the one hand, with the alarm wheel 7 and, on the other hand, with a gear connecting it with the barrel and with the escapement of the alarm system which is not illustrated.
  • FIG. 1 illustrates the mechanism in the position assumed by it after the automatic interruption of the ringing of the alarm, said mechanism being thus ready to produce the next signal.
  • the hour Wheel 5 is spaced with reference to the alarm wheel 3 under the action of the pro ections 6 carried by said wheel 5.
  • the lever 13 which engages permanently the hour wheel 5 is thus in a raised position for which its tail piece 19 holds the hammer fast I through the depending section 23 of the spring 21.
  • the spring 12 holds the pin 10 on the stop wheel in contact wlth one end 31 of the opening 8 in the alarm power wheel 7.
  • the ringing of the alarm is consequently stopped at that moment, its duration being limited to the angle of unwinding of the barrel leading to the shifting of the stud 11 from the position occupied in FIG. 1 to that occupied in FIG. 3, so as to lift the angle bar 18.
  • the hour wheel is raised again above the alarm wheel 3 and reengages the lever 13 which is urged against it by the spring 16 so as to raise the angle bar 18 from conical stud 11.
  • the stop wheel 9 is consequently released and, by reason of the action of the spring 12 on the pin 10, said wheel 9 is caused to rolate and to return into the position illustrated in FIG. 1.
  • the user may exert a pressure on the knob 29 which, through the agency of the shank 28 and of the pin 27, rocks the yoke 25 round the pillar 15.
  • the conical stud 26 on the yoke I engages therefore the lower surface of the lever 13 and raises it.
  • the tail piece 19 of said lever 13 is thus inserted in the path of the spring 23 acting on the hammer and interrupts the ringing of the alarm.
  • the yoke is held fast in the position assumed by it by reason of the pressure exerted by the spring 16 on said conical stud 26.
  • the hour wheel moves again away from the alarm wheel, the lever 13 is raised further and the yoke 25 is released. Under the action of its spring 33, the yoke returns into its starting position (FIG. 1) while urging the stop-controlling knob 29 back into its inoperative position.
  • the alarm time piece thus executed with a provision of movement for seven days ensures a reliable operation for the user since the mechanism prepares, after each manual or automatic stopping of the ringing of the alarm, the next alarm period and cuts out the necessity of any manual operation on the stop-controlling knob.
  • an alarm time-piece including a movement, an alarm mechanism, an alarm lever operatively connected with the alarm mechanism to normally lock the latter and adapted to be shifted positively by the movement transversely of the movement at a predetermined adjustable moment to transiently release the alarm mechanism
  • a manually operable stop-controlling knob a yoke adapted to pivot in a plane parallel to the movement, between a position slightly to one side of and underneath the alarm lever and a position registering vertically with the latter to be urged by said knob when depressed into its last-mentioned position to engage the alarm lever when in its alarm-releasing position and raise the latter into its alarm-locking position and hold it therein
  • a spring urging the alarm lever into its alarm-locking position for engagement with the yoke in its last-mentioned position, the next release of the alarm lever by the movement disengaging the yoke with reference to the latter
  • elastic means urging the yoke when disengaged from the alarm lever back into its starting position to thereby also
