Abstract
An elapsed time hour meter for measuring and indicating an amount of elapsed time used in many types of applications. The elapsed time hour meter has a cylindrical rotating counter indicator that indicates the amount of elapsed time, and it is driven by an electrically powered watch movement. The gear work of the elapsed time hour meter couples the watch movement to the rotating counter whereby the watch movement drives the counter indicator to measure and indicate the actual amount of elapsed time. The watch movement is a reliable production wrist watch without battery, face and hands and to the minute stem of which is affixed a minute gear coupled to an intermediate gear supported on a lower housing half which couples to the counter indicator. The power supply elements and external terminals are supported in the upper housing half. The elapsed time hour meter is versatile and reliable and has the advantages of being small in size, low in cost, and low in power consumption.
