ABSTRACT:
A liquid operated clock employs buckets pivoted to arms of a carrier rotating at constant speed. The buckets are sequentially moved below the surface of a liquid reservoir to fill the buckets, elevate them and cause them to discharge into a receiver. After a predetermined number of buckets of liquid have accumulated within the receiver, it is suddenly drained by a siphon tube back into the liquid reservoir. The change in weight of the receiver between full and empty conditions operates through a ratchet mechanism to drive the input shaft of a clock mechanism in an intermittent fashion. Cam and follower means control filling and dumping of the buckets.
