Abstract
867,633. Gearing for starting and stopping machinery. ZAVODY V.I. LENINA PLZEN, NARODNI PODNIK. April 10, 1959, No. 12194/59. Class 80 (2). A crank-shaft 3 is driven intermittently from a constantly driven shaft 24. Stepped bevel wheels 25, 26 mesh bevel wheels 9, 13 on hollow shafts 27, 28 to drive them at speed ratio of 3: 1 respectively. Shaft 27 carries a pawl 12 engageable with a tooth 8 fast with a crank disc 4 of the shaft 3. The hollow shaft 28 carries a cam 14 engaged by a follower roller 15 connected by a two-arm lever 16 (which is pivoted at 17) to a roller 19 which, when roller 15 is displaced by a swell of the cam, contacts a tail of the pawl 12 to disengage it from the tooth 8 and thus discontinues the drive of shaft 3. A member 20 associated with the roller 19 applies a brake (Fig. 7, not shown) to station the shaft 3. The pawl release and brake mechanism is duplicated at the opposite side of the shafts, and thus for half a revolution shaft 3 rotates with the shaft 27, followed by a dwell during a complete revolution of the shaft 27, and so on.
