Abstract
1,252,654. Ratchet mechanism. SIEMENS A.G. 31 Jan., 1969 [31 Jan., 1968], No. 5438/69, Heading F2Q. [Also in Division H1] The stepping drive to a programmer for washing machines, for example, comprises a pawl 10 pivoted at 25 on a lever 8 which is oscillated about shaft 9 by a slide block 19 moved by an eccentric 7 driven via reduction gearing 18, 17, 16, 15 by a motor (5, Fig. 1, not shown). The pawl 10 has a knife-edge nose (11) which engages ratchet teeth near the peripheries of the end faces of a cam wheel (2) and a cam drum (1) coaxial with shaft 9 (see Division H1). The lever 8 may be of plastics material and the pawl pivot 25 and block 19 may be snapped into position therein. The aperture 21 to receive the eccentric 7 may be disposed eccentrically in the block 19 such that transposition of the block 19 with respect to the lever 8 (for example, turning it through 90 degrees) will provide some adjustment of the pawl 10 with respect to the ratchet teeth.
