1,069,894. Linkwork. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 8, 1964 [May 10, 1963], No. 19387/64. Heading F2K. The articulated arms 1, 21 of a remote handling linkage are coupled for opposite angular movement by pulleys 7a, 7b and 8a, 8b fast therewith and connected by compensation cables 9a, 9b thus maintaining constant the length of transmission cables 4 between free pulleys 5, 6. Each set of arm-pulleys 7a, 8a may have two crossed compensating cables with helical pulley attachment grooves 22. Connecting link 3a may be adjustable for cable tensioning. In a modification, Fig. 2 (not shown), articulated arms (11, 2) of a polygonal linkage are coupled by compensating cables (16, 17) and (9) running over free pulleys (15, 7) between pulleys (14, 8) fast with arms (11, 2). |
