A clock for indicating time for effectively all the countries and time zones of the world, the hour hand of the clock being in the form of a disc that rotates once every twenty-four hours against a twenty-four hour scale. The disc having projected thereon a map of the world centered on the South Pole with the majority of the time zones positioned in accurate longitude around the periphery of the disc. The clock also included indicators for each time zone to provide simple visual indication of th...

A clock has a clockwork movement enclosed in a soundproof case of expanded plastic material having a substantially non-porous smooth outer surface and a sponge-like inner cellular structure. The dial and hands and, possibly, a sonorous alarm are located outside the case.

A clock in which planetary gear wheels provided with inner teeth engage on stationary elements with outer teeth to obtain uniform rotation for successive gear stages. The eccentric drive of one stage necessary for engagement is directly effected by the eccentric shape of the rotating element of the preceding stage. The rotating elements belonging to each stage act as moving elements and also as indicating elements due to their markings.

A clock frame has front supporting bars extending radially inwardly therefrom. A central panel which is substantially smaller than the clock frame is supported in the front central portion of the frame by the support bars, and a clock mechanism is attached to the central panel. The drive shafts of the clock mechanism extend rearwardly from the central panel and have a pair of hands attached thereto which project radially beyond the central panel so as to be visible from the front of the clock. T...

An advertising display receiving surface, one side of which has an overlay comprising an advertising insert sheet that is readily removable and replaceable. An electronic clock motor is on the other side of the surface. The display receiving surface acts also as the face of the clock, but lacks the dial. The advertising display sheet contains the dial and is transparent at the portion of the display sheet that overlays the area swept by the clock hands. The display insert is readily replaceable ...

A clock in the form of a traffic light, with time designations shown in the red, amber and green lenses. The time designations include the day of the week, hour of the day, and month and date.

A clock having a housing which contains two internal disks and a motor for rotation of those disks on a shaft is disclosed. An hour disk is provided having a shaded region representing night and an unshaded region representing day. The hour disk is positioned to appear through a opening in the clock face. The face of the clock may have one or more openings to expose the minute and hour disks. One of the openings has a numerical representation of hours provided on the clock face there around. The...

A clock has a timepiece movement and a dial disposed on the front face of a base plate. A transparent cover plate having front and back faces is spaced apart from the dial to define a space between the back face of the cover plate and the front face of the dial. Decorations are fixed to the peripheral portion of the front face of the cover plate to define time reference members, and a clock hand is disposed in the space and driven by the timepiece movement to move relative to the time reference ...

A clock comprising capsule in which a timepiece movement is incorporated, a install plate on which the capsule is fixedly attached, a dial disposed in front of the install plate, a transparent front cover disposed in front of the dial, and hands disposed in a gap between the front cover and the dial and driven by said movement, characterized in that projections are integrally formed on the front cover so that tip ends of the projections are made to come to close to or to abut against a front sur...

A clock has a movement with protruding nested drive shafts. A housing member has a wall and a ridge which is forwardly offset from the wall. A planar dial rests against the ridge and is formed with an aperture in register with the aperture of the wall with the nested shafts extending through the apertures. A securing device engages the front of the dial, extends through the aligned apertures and engages a fixed member of the movement thereby holding the dial against the ridge.
