Definitions

  • the new hand-setting device according to the invention is characterized, in that during the depressing movement of the handsetting knob a predetermined part carrying the second hand is automatically coupled with a wheel, which rigidly connects with the gear change, which in turn is in engagement with the pipe joints or cannons of the minute and hour hands.
  • FIG. 1 is a vertical sectional view through a first embodiment pursuant to the invention having an axially displacable spindle of the second hand.
  • FIG. 2 is a somewhat modified sectional view through another embodiment according to the invention showing a device with a tubular or cannon connection carrying the second hand.
  • gear wheel 16 With the change wheel or gear mechanism 11, 13 there is rigidly connected gear wheel 16 (FIGS. 1, 2). If in the embodiment of FIG. 1 spindle l is pushed inwardly via clutch part 12 by means of a hand-setting knob (not shown), the pinion 17 rigidly arranged on the seconds spindle 1 comes then into mesh or engagement position with gear wheel 16. Now if in this position the said spindle is turned by a knob to set the hands, the minute hand support 10 and the hour hand support 15 are adjusted at the same time via change wheel 11 and pinion 13.
  • the hour hand support 15 with hour wheel 14 and the intermediate wheel spindle 6 with wheel 5 and pinion 7 have been omitted fro the sake of greater clarity.
  • a pinion 25 is provided which is in permanent engagement with wheel 16 of the gear change set-up 11, 13.
  • Spindle 1 carries at its front end a clutch covering or like lining 22, which is normally coupled with the front face serration 23 of a tubular support element or cannon 24 which carries the second hand 20. If the hand-setting knob 30 is now pushed inwardly against coil spring action 30a, the clutch member 26 couples with first serration 23 at one end of the support 24. If the hand-setting knob is pushed farther in, tubular support 24 is displaced axially inwardly according the arrow, its second end serration 28 being then coupled or in mesh with corresponding serrated face plate 22a of the pinion 25.
  • the special lining 22 is rendered permanently magnetic, so that the end serration 23 is attracted by the magnetic lining 22 when the hand-setting knob is in the in operative position according to FIG. 2.
  • FIG. 2 there is shown further the minute hand 19, which is arranged on the minute hand pipe support or cannon 10.
  • an extremely efficacious, compact and sturdy hand setting mechanism equipped with a spring-supported operating knob characterized by operable means 1 or 24 carrying the seconds hand 20 and provided with coupling means 17 or 28, 28a establishing during knob depressing movement in spindle direction operative connection of said coupling means with a change gear mechanism 16, l 1, 13, which is constructed to transmit via said knob rotative engagement with respective support means l0, for the minute and hour hands in order to set the same.
  • Said spindle 1 is axially displaceable, said coupling means being constituted by a pinion 17 or gear wheel which during knob movement comes to mesh with the aforesaid change gear mechanism.
  • the seconds hand 20 includes a support or cannon 24 which is provided at one end with serrations 23 and with a clutch covering 22 carried by the spindle 1 which passes through said cannon.
  • the opposite end of the cannon is provided with other end serrations 28; a pinion 25 being in permanent engagement with said gear mechanism and said other end serrations 28 come thus to mesh with a serrated top face plate part 28a of the pinion 25 upon further or terminal knob depression, whereupon the minute and hour hands can beset without actuating the 4 spindle.
  • a device for setting the minute and hour hands of a timepiece in particular of a car clock, equipped with sweep seconds hand, and having a hand-setting knob the axis of which is aligned with a spindle passing hand; characterized by operable means carrying the seconds hand and provided with coupling means establishing during knob depressing movement in spindle direction an operative connection of said coupling means with a change gear mechanism, which is constructed to transmit via said knob, rotative engagement with respective support means for said minute and hour hands in order to set same.
  • said coupling means including a gear wheel operatively connected to said seconds hand, and friction means joining said spindle with said seconds hand.
  • a device characterized in that said seconds hand is mounted on a cannon, said spindle passing through said cannon, which is provided at one end with serrations and with a clutch covering which is disengageable via said spindle from said one end serrations during preliminary knob depressing movement, said cannon having further an opposite other end provided with end serrations, and a pinion arranged in permanent engagement with said change gear mechanism and provided with a serrated plate face engageable with said other end serrations of said cannon upon farther knob depressing movement.
  • said covering consists of permanently magnetic material normally attracting said one end serrations of said cannon when said knob is in its inactive position, in which said serrated plate face is disengaged from said other end serrations.
