Abstract

783,909. Linkwork. GIESSEREI & MASCHINENFABRIK OSTERWALDER AKT.-GES. May 2, 1955 [April 30, 1954], No. 12634/55. Class 80 (3). A rod 2 and plate 3 forming a toggle between an abutment 4 and a reciprocable press ram 1 are actuated by a lever 5 pivoted at 6 to two connecting-rods 7, 11 actuated respectively by a crank 8 and an eccentric 12 on intergeared shafts 9, 13 driven at the same speed but in opposite directions by an electric motor 17. The gear 14 is slidable on the shaft 13 so that the angular relation between the shafts 9, 13 may be varied to vary the ram stroke. With the arrangement shown, the time taken for a half-cycle measured from the mid-stroke position is considerably longer in the front half of the stroke than in the rear half so as to prolong the operating time and allow deformed material to flow. Interchangeable eccentrics may be provided to vary the throw of the crank or eccentric.
