    摘要： A tensioner for a spring-loading device (12) of a power switch comprises a pivoting hand lever (46) and a ratchet wheel (47) which can be rotated in steps by a transport pawl (50) and prevented from rotating backwards by a locking pawl (52). A cam disc (13) acting on the spring (12) can be rotated by the ratchet wheel (47). A catch (61) on the cam disc (13) and a projection (64) on the set-back edge (63) of the cam disc (13) control a device for interrupting the transmission of force from the hand lever (46) to the ratchet wheel (47) once the spring (12) is fully tensioned.

    摘要： The present invention relates to an operating mechanism for a circuit breaker; having an opening means (3) carrying out open-circuit operation by deenergization thereof and a clos­ing means (7) carrying out closing-circuit operation by rotation of a cam (11) caused by deenergization of the closing means so that the opening means conserves energy by deenergization of the closing means and the closing means conserves energy by rotation of the cam; and the operating mechanism according to the present invention is provided with a large gear (8) fixed coaxially with the cam and lacking in teeth in part (8a) and a small gear (9) rotatably driven by a drive source in relation of engaging with the large gear, so that the non-tooth portion of the large gear is provided at the position thereof where the large gear disengages from the small gear just after the closing means completes its energy conservation, whereby the small gear, after completion of energy conservation of the closing means is completed, runs idle in the non-tooth por­tion and the drive source for the small gear is free from pulsation of a load and the drive source smoothly rotates, resulting in that a small drive source is enough for use and the large gear and small gear are not subjected to an over­load, thereby the present invention can provide an operating mechanism of a large current and a large capacity.

    摘要： In a switch operating mechanism in which the elastic force of a spring energized is trasmitted through a link mechanism to achieve a switch opening or closing operation, one end of a first torsion bar (28, 29) is fixedly secured to a rotatable member (26, 27) while the other end is fixedly secured to a stationary part (1) of the mechanism, and one end of a seocond torsion bar (34, 35) is fixedly secured to the rotatable member (26, 27) in such a manner that the one end is diametrically opposite to the one end of the first torsion bar while the other end (32, 33) is rotatably supported by the stationary part and coupled to the link mechanism.

    摘要： A device for controlling the rotation of shaft (12) through a preselected angle narrower than 360°. On the shaft there are mounted two fresh-wheels (10,11) one at least of which is actuatable by a lever (18) to which a predominantly rectilinear reciprocation is impressed. The connection between the lever (18) and the outer ring (17) of the free-wheel is embodied by a pin (25) integral with the ring and engaged by a slot (26) formed in the vicinity of the free end of the lever. The slope of the slot is such that in the thrust stroke of the lever it causes the lever end to approach a cylindrical race (29) of a disc (28) keyed to the shaft (12) beside the free wheel. In a determined position this race is cut away by a hollow space (30) so that when the lever end arrives in registry with the hollow space, it can be depressed and thus it prevents the drive transfer for the free-wheel ring.
