Abstract: A stator comprises a one-piece U-shaped stator sheet having a pair of elongate parallel legs. The legs form pole shoe bridges at their front ends for their reception of a driven motor. At least one of the pole shoe bridges interconnects the legs adjacent their front ends. A coil-carrying bobbin is mounted on one of the legs, the length of the wound coil being longer than its diameter. A separate yoke sheet is fastened to the legs adjacent rear ends thereof to secure the bobbin on the leg. The stator is formed by first stamping-out a stamping which includes the parallel legs and the yoke, with the yoke being integrally attached to the legs by means of webs. After the stamping undergoes the usual pretreatment, the yoke sheet is separated from the legs, whereupon the coil bobbin is slipped onto the leg from the rear. Then, the yoke sheet is secured to the rear ends of the legs to prevent removal of the coil bobbin.

Abstract: A clock movement comprises front and rear housing shells. A support plate is mounted within and between the shells. A gear movement is mounted on a rear side of the support plate and faces the rear shell. A hands movement is arranged on a front side of the support plate and is drivingly connected to the gear movement. A circuit board is connected to the support plate. A motor for the gear movement comprises a stator sheet and a coil bobbin. The stator sheet is fastened in engaging relationship to a rear side of the support plate adjacent a rotor opening in the stator sheet. The coil bobbin is mounted on the stator sheet and includes a plurality of pins which define coil terminals. The pins are soldered to a circuit of the circuit board. The circuit board is disposed in front of the support plate in spaced relationship therewith and is of arc-like configuration such that legs of the arc straddle the minute and hour wheels of the hands movement.

Abstract: A timepiece drive assembly is adapted to be mounted in a timepiece housing, e.g., a small designer desk clock. The assembly includes a movement casing equipped with a removable battery-receiving member in which battery contact terminals are releasably arranged. The contact terminals are connected by means of flexible connecting lines with the circuit board of the movement. The movement casing may be arranged in a cylindrical part of the clock housing, while the battery-receiving member is located in a pedestal provided underneath the cylindrical part. It is only necessary to equip the pedestal with fastening means for the battery-receiving member and not with the more expensive individual fastening means for the holding and contacting of the battery. Thus, substantially flexibility is obtained in the design of the timepiece housing because the battery-receiving member can be connected to the movement casing or spaced therefrom.

Abstract: A contact arrangement for a battery-operated instrument, especially a battery-operated clock, having a housing made of synthetic material. Two contact elements are provided for making connection between the two terminals of a battery and two respective paths of a circuit board. One of the contact elements includes a bus portion fastened to the housing, and a pair of legs. A first leg makes contact with one terminal of the battery and the second leg makes contact with a path of the circuit board. The second leg is designed in the form of a knife-edge contact, one portion thereof bearing against a wall of the housing, and another portion thereof bearing against the circuit board. The second leg thus holds the circuit board in its inserted position by mechanical force. The contact element further includes a third leg which electrically contacts as well as mechanically clamps a small bulb when the latter is inserted into the housing.

Abstract: An on-off slide switch is arranged on a circuit board, preferably that of a battery-operated electronic clock, for actuating a stepping motor thereof. The slide switch can be moved to different positions and interacts with several electric paths of the circuit board. The switch is arranged movably along one edge of the circuit board and bears against such edge via guide elements. The switch carries at least one contact element for shunting a plurality of tracks of the board and a grip for its manual operation. The slide switch, together with all elements carried by it is designed in the form of a punched-out, flexible metal part and is easily installed on or removed from the circuit board without the need for separate fasteners.

Abstract: A clock is disclosed comprising a housing which includes mounts for supporting clockhands, and a clockwork for driving the hands. The clock also includes a motor, an electronic circuitry for conducting electrical power to the motor, and a circuit board. The motor includes a coil, a stator, and a rotor. The circuit board includes means for carrying the electronic circuitry, coil and stator externally of the housing to form a pre-assembled module which can be pushed into the housing into contact with respective retaining parts on the housing.

Abstract: An electrical contact arrangement is disclosed for a battery-operated instrument, especially a battery-operated clock having a housing made of synthetic material such as plastic. Two contact elements are provided for connecting two terminals of the battery with two respective paths of a circuit board. One of the contact elements comprises a bus fastened to the plastic housing, and several legs. A first leg makes contact with one terminal of the battery and the second leg makes contact with a path of the circuit board. The second leg is designed in the form of a knife-edge contact with a first portion bearing against a wall of the housing and a second portion bearing against the circuit board, the latter having been inserted into the housing parallel with such wall. The second portion of the contact engages an appropriate path of the board.

Abstract: A drive arrangement within a small electric instrument, especially a battery-operated electronic clock, includes a circuit board. Mounted on the circuit board, in addition to the electronic circuitry, are at least the static components of a motor which can be mounted on the circuit board prior to its installation. The circuit board and such static components can thus be inserted as a unit into the clock housing and into suitably designed receiving elements. The receiving elements position the circuit board, as well as the components arranged thereon, into the proper locational relation to the other parts of the motor or clock. The circuit board is held in place after its insertion into the housing by a battery contact spring which is designed in the form of a knife-edged contact and which presses laterally against the circuit board, thus holding the board in its inserted position without the need for additional fastening means.

Abstract: Gear drive enclosure, preferably for battery-operated clocks whose drive is supported in and on both sides of a single base plate, and wherein the latter has a plastic housing cover or capsule and a support plate coordinated thereto. The plastic capsule limits one side of the gear mechanism, which has an indicator mechanism provided thereat, while the support plate limits the other side of the gear mechanism.
