    摘要： In a timing device for time switch comprising a scale plate rotated at a constant rate and possessing presetting element plug-in portions involving slots, grooves and the like corresponding to time scale on the circumferential part thereof and presetting elements to be inserted to fit into the plug-in portions of the scale plate, this scale plate is composed of a molded plastic guide portion serving to position the presetting elements and to keep the position of each presetting element inserted in the prescribed position, and a metallic body inserted in the plastic guide portion in such that a portion with which the presetting element resiliently engages comes to be a metallic portion.

    摘要： A programmer/timer for an appliance of the type having a rotatable cam drum (12) advanced for sequential actuation and deactuation of a plurality of electrical switches (20). The drum is advanced or indexed intermittently by an oscillating advance pawl (26) engaging a ratchet wheel (25) and also continuously by a gear (44) driven by a common motor for oscillating the advance pawl. The ratchet wheel (25) has a hub (38) which is frictionally engaged (37) to drive the cam drum. The driven gear in turn is frictionally engaged (51) with the hub to also drive the ratchet wheel. When the advance pawl engages the ratchet wheel for intermittent drive, the driven gear slips on the ratchet hub. Upon user selection, a separate cam track (52) lifts the advance pawl to permit the driven gear to continuously drive the ratchet wheel.

    摘要： The timing cam (10) is advanced for switching purposes by a first reciprocating pawl (28) acting on ratchet teeth (30) molded on the timing cam (10). When the program requires a timed period during which conditions remain the same, the ratchet teeth (30) are spaced so that the pawl (28) cannot pick up the next tooth until the cam is advanced by a second smaller pawl (54) acting on a separate ratchet (56) provided with small, closely spaced teeth. This separate ratchet (58) has a pinion gear (62) driving a ring gear (64) molded inside the timing cam. The steps imparted to the timing cam by the small pawl and ratchet are very small and consume appreciable time - the lenght of time taken to position the next tooth for engagement by the large pawl being determined by the space between the large teeth.
