    • An electronic timer for producing a printed record of time intervals. The timer includes manual, photoelectric, acoustic signal, and other trigger source actuation and can simultaneously measure and record two or more events on separate channels and produce printed records for each. The apparatus is powered by self contained batteries which power a clock oscillator, all electronic timing circuitry and the record or paper tape mechanism. The timer includes a pair of time counters and storage for each channel which allow the continuous measurement of total time while measuring and recording intervals such as individual laps. The interval recorder automatically commences measuring a new interval upon termination of the last interval whereby the timer may record continuous sequences of intervals while simultaneously recording the overall time. The apparatus includes a printing and paper advance mechanism including solenoids which drive the paper against marking devices to indicate the appropriate indicia as the paper is discharged.

    • A time clock is provided which includes a minute wheel that is advanced every minute and an hour wheel that must be advanced every hour, wherein a deflecting pawl device is utilized, in place of gears, to connect the wheels. Both wheels have ratchet teeth, and a pawl that oscilltes once each minute to advance the minute wheel. The minute wheel, which rotates once every hour, has a cam that moves beside the pawl to deflect it sidewardly so that the pawl engages a tooth on the hour wheel. Thus, at the next oscillation of the pawl, both wheels are advanced. The minute wheel bears the numbers 0 through 59, while the hour wheel bears the numbers 1 through 12 repeated five times, so that both wheels have 60 numbers.
    • 提供了一种时钟,其包括每分钟前进的分轮和必须每小时前进的小时轮,其中使用偏转爪装置代替齿轮连接车轮。 两个轮子都有棘轮齿和一个每分钟振动一次以推进分轮的棘爪。 每小时旋转一次的分轮具有在棘爪旁边移动以将其侧向偏转的凸轮,使得棘爪接合时轮上的齿。 因此,在棘爪的下一个摆动时,两个轮都前进。 分针的数字为0到59,而小时轮则重复了数字1到12,重复了五次,这样两个轮都有60个数字。
