Claim 1

IN A HOROLOGICAL DEVICE: A FRAM ESTRUCTURE INCLUDING A VERTICAL FRONT WALL PORTION HAVING APERTURES THEREIN, FIRST SECOND AND THIRD DRUM ASSEMBLIES SUPPRORTED FOR ROTATION ABOUT A COMMON HORIZONTAL AXIS BEHIND SAID WALL PORTION FOR DISPLAYING TIME INDICATIONS THROUGH THE APPERTURES THEREOF, EACH ONE OF SAID ASSEMBLIES COMPRISING A SHAFT SUPPORTED FOR ROTATION AROUND SAID HORIZONTAL AXIS, TWO SPACED PARALLED PLATES SECURED TO SAID SHAFT, AND A PLURALITY OF BLADES OF ESSENTIALLY RECTANGULAR SHAPE POSITIONED BETWEEN SAID PLATES, EACH BLADE HAVING TIME INDICATING INDICIA THEREON AND BEING FREELOY SWINGABLY CONNECTED TO SAID PLATES FOR OSCILLATION ABOUT A HORIZONTAL AXIS LOCATION ADJACENT ONE EDGE OF SUCH BLADE, THE BLADES BEING EVENLY ARRANGED ON THE PLATES WITH THE AXIS OF OSCILLATION THEREOF FORMING A CIRCLE, WHEREBY UPON ROTATION OF SAID ASSEMBLIES THE TIME INDICATING INDICASEQUENTIALLY APPEAR AT THE APERTURES OF SAID FRONT WALL PORTION AS SAID BLADES ARE CAUSED TO SEQUENTIALLY DROP FROM AN UP-TURNED VERTICAL POSITION TO A DOWN-TURNED VERTICAL POSITION, THE BLADES RELATED TO SAID ASSEMBLIES BEING CORRELATED RESPECTIVELY THE MINUTES, TENS OF MINUTES AND HOURS, A TIME-CONTROLLED SOURCE OF ROTARY MOTION HAVING AN OUTPUT SHAFT DRIVEN AT A RATE OF SPEED OF ONE REVOLUTION PER MINUTE, A FIRST ELLIPTICAL GEAR WHEEL SECURED TO SAID OUTPUT SHAFT A SECOND ELLIPTICAL GEAR WHEEL IN MESH WITH SAID FIRST GEAR WHEEL AND DRIVEN THEREBY IN ROTATION AT ONE REVOLUTION PER MINUTE AT SEQUENTIALLY ACCELERATED AND DECELERATED SPEEDS, AND FIRST GEAR MEANS CONNECTING SAID SECOND ELLIPTICAL GEAR WHHEL TO THE SHAFT OF SAID FIRST ASSEMBLY FOR IMPARTING THERTO A FRACTIONAL ROTATION AS SAID SECOND ELLIPTICAL GEAR WHEEL IS ACCELERATED TO CAUSE ONE BLADE OF SAID FIRST ASSEMBLY TO DROP FROM SAID UP-TURNED POSITON TO SAID SHAFT TURNED POSITION, SECOND GEAR MEANS CONNECTING THE SHAFT OF SAID FIRST ASSEMBLOY TO THE SHAFT OF SAID SECOND ASSEMBLY FOR IMPARTING TO SAID SECOND ASSEMBLY A FRACTIONAL ROTATION TO CAUSE A BLADE OF SAID SECOND ASSEMBLY TO DROP FROM ITS UP-TURNED POSITION TO ITS DOWN-TURNED POSITION AS SAID FIRST ASSEMBLY HAS COMPLETED ONE REVOLUTION, AND THIRD GEAR MEANS CONNECTING THE SHAFT OF SAID SECOND ASSEMBLY TO THE SHAFT OF SID THIRD ASSEMBLY FOR IMPARTING TO SAID THIRD ASSEMBLY A FRACTIONAL ROTATION TO CAUSE A BLADE OF SAID THIRD ASSEMBLY TO DROP FROM ITS UP-TURNED TO ITS DOWN-TURNED POSTION AS SADI SECOND ASSEMBLY HAS COMPLETED A GIVEN ROTATION, WHEREBY EACH FRACTIONAL ROTATION OF EACH ASSEMBLY IS IMPARTED BY A TEMPORARILY ACCELERATED MOTION THROUGH THE SHAFT OF SAID FIRST ASSEMBLY.
