摘要： A digital timer having a timer mechanism and a drive unit carried by a frame together with a setting device to set a selected period of time that the timer mechanism is to run and for interconnecting the drive unit to the timer mechanism to cause the drive unit to drive the timer mechanism for only that set period of time. The timer mechanism has digital reading members for directly indicating the setting of the timer mechanism to the selected period of time with such digital reading members providing a countdown readout of the set period of time as the same is elapsing.

摘要： A digital clock construction having a frame carrying a rotatable shaft driven by a timer at a predetermined rate. A plurality of time indicating wheels are rotatably mounted on the shaft. A first drive structure is carried by the shaft and is operatively associated with one of the wheels for incrementally rotating the one wheels relative to the shaft on a time basis as the shaft rotates. Other drive structure is operatively associated with the shaft and the remaining wheels to tend to rotate the remaining wheels as the shaft rotates. Latch structure is operatively associated with the one wheels and the remaining wheels for holding the remaining wheels from rotating relative to the frame except in a timed relation to the incremental movement of the one wheels relative to the frame.
摘要翻译：一种数字时钟结构，具有承载由定时器以预定速率驱动的可旋转轴的框架。多个时间指示轮可旋转地安装在轴上。第一驱动结构由轴承载并且可操作地与其中一个轮相关联，用于当轴旋转时基于时间基准相对于轴逐渐地旋转一个车轮。其他驱动结构与轴可操作地相关联，并且随着轴旋转，剩余的轮倾向于旋转剩余的轮。闩锁结构可操作地与一个车轮和剩余的车轮相关联，用于保持剩余的车轮相对于车架旋转，除了与一个车轮相对于车架的增量运动的定时关系。
