An electric clock mounting and contact apparatus including an electric clock housing, an electric drive circuit positioned within the housing, pillar means extending between the housing and the electric drive circuit for supporting said electric drive circuit, the pillar means being electrically conductive and in electrical contact with the electric drive circuit, an electrical contact means connected exteriorly of the electrical clock housing and to the pillar means, said electrical contact means being operable for electrical contact with a voltage source exterior of the electric clock housing.
In a battery powered clock movement, there is an improved connector means including a single fastner means as the sole means for securing the plate means and the housing cap means together.
A battery operated quartz crystal controlled alarm clock includes a single printed circuit board having a quartz crystal controlled oscillator and an oscillator controlled drive circuit mounted directly on the single printed circuit board. Additional components as for example a time display unit, an alarm signal source, a disconnect switch for the alarm signal source and one or more batteries are all arranged directly on the same circuit board with direct electrical contact being established between the components and the conductive areas plated on the circuit board. The release spring of an electro-mechanical movement is mounted on the conductor side of the circuit board and serves to establish electrical contact between two conductive areas of the circuit board to complete an electrical circuit for energizing the alarm signal source. The movement is mounted on the opposite side of the printed circuit board and communicates with the release spring through an aperture formed in the printed circuit board. All of the electrical connections are designed to substantially reduce the number of connecting members and the number of soldering operations required to produce the clock.
An electrically powered timer mechanism includes a mounting plate and a conductor plate securable thereto. The mounting plate carries a timer mechanism, including a magnet assembly. The conductor plate carries a coil which is disposable in operating relationship with the magnet assembly when the mounting plate and conductor plate are connected. The mounting plate includes a slit which is predisposed relative to the magnet assembly for receiving the coil. The conductor plate has an aperture which can be placed on a peg of the mounting plate. The coil can be inserted into the slit to insure instant alignment relative to the magnet assembly. A screw can then be inserted to fixedly couple the mounting plate and the conductor plate.
