Abstract

971,914. Gearing for conveying rotary motion; variable speed ratchet gearing. VIRGINIO RIMOLDI & C. S.p.A. March 28, 1961 [April 8, 1960], No. 11343/61. Headings F2D and F2Q. [Also in Division D1] The vertical feed-shaft 115 of an overedge stitch sewing machine is given a step-by-step rotational movement from the main driving- shaft 39 of the machine through an oscillating lever 101 and a one-way coupling, and is held by a one-way brake against rotation in the other direction. The one-way coupling and brake comprises cam members 105, 106 carried on the shaft 115 within casing members 102, 103, respectively, the latter member being fixed and rollers 107, 108 being disposed between the corresponding cam and casing members. The cam members 105, 106 are arranged so that shaft 115 is carried along by rotation of member 102 by lever 101 in one direction while it is held by the fixed member 103 when the member 102 is rotated in the opposite direction. The member 102 is oscillated by drive means comprising an eccentric 87 on the main shaft 39 coupled to one end of a rod 91 adjustably slidable in a cylindrical pivot pin 120, the other end of the rod being coupled to one arm 94 (see Fig. 4) of a bell-crank lever, the other arm of which carries a block engaging a slot in lever 101 attached to member 102. The pivot pin 120 is carried at one end of a lever 122 pivoted at 123 and its position is adjusted by an eccentric 126 rotated by a calibrated knob to vary the oscillation of the lever 101 and the feed increment of shaft 115.
