Abstract
710,689. Converting rotary into reciprocating motion. COSMANN, F. May 23, 1952 [May 26, 1951], No. 13072/52. Class 80 (1) [Also in Group XXI] To impart to a cable under tension, such as the supporting cable of a percussive boring tool or the monkey of a pile driver, a reciprocatory motion at a high speed in one direction and at a low speed in the other direction there is provided a mechanism consisting of a pulley 13 that engages the cable 7 and is carried on a crank 14 secured to a shaft 15 on which rotates a continuously driven gear wheel 17, Formed on the internal peripheral flange 20 of the gear wheel are teeth 19, which are engaged by a spring loaded pawl 25 mounted on a radial arm or arms 21 secured to the shaft 15. In operation the'pawl 25 when at its lowest position engages the teeth 19 so that the gear wheel 17 for half a revolution by means of the pawl 25, arms 21 and shaft 15 causes the crank 14 to deflect the cable 7. At the end of the half revolution of the gear wheel 17 the pawl 25, due to the tension in the cable 7, rapidly passes over the teeth 19 until it again reaches its lowest position and the cycle of operations is then repeated. The gear wheel 17 may be replaced by a pair of wheels interconnected by pins with which the pawl now mounted between the wheels engages.
