Abstract

1390198 Jacks having flexible thrust chains MANUFACTURE DE MACHINES DUHAUTRHIN and CENTRE D'ETUDES ET D'APPLICATIONS DES TECHNIQUES DE PRODUCTION CTP 26 April 1972 [26 April 1971] 19481/72 Heading B8J [Also in Division F2] A jack comprises a chain rigid under compression when extended by rotation of a drive wheel 3 in a casing 4. The drive wheel 3 divides the chain into an active part A and an inactive part B. The inactive part B is bolted to the casing 4 at 10 and is wrapped around a chain wheel 8 free to move with the inactive part B as it is folded up at half the speed of the active part A. The effective length of the jack can be altered by adding or removing links at the inactive end at 10. In a modification, the inactive portion (B<SP>1</SP>) of the chain is diverted a further 90 degrees so as to be parallel to the active portion A<SP>1</SP>, Fig. 2 (not shown). In a further embodiment, Fig. 3(a) (not shown), the inactive portion (B<SP>11</SP>) is arranged in three parallel sections, its end link being attached by bolts (10<SP>11</SP>) to a moving guide-plate (11) after passing around a chain wheel (13) carried by the casing (4<SP>11</SP>) and driven from the wheel (3<SP>11</SP>) through a reduction gear.
