Patent ES-402067-A1 (ES)
Title: Chain-type jack for handling tensile and compressive loads
IPC: B66F3/06
Filed: 1972-04-25
Abstract: An improved jack includes a fixed housing through which an elongated drive chain extends. A sprocket within the housing advances and retracts the chain through the housing via forward and rearward exit ports to provide a desired change in the direction of motion of the chain. The portion of the chain extending from the rearward port of the housing is further rotated back on itself through engagement with a floating guide member. The rear end of the chain is suitably anchored. The combination of the guiding member and the anchoring means serves to restrict the overall rearward extension of the guide member to a prescribed fraction of the forward extension and permits the form factor of the jack in its retracted position to be smaller than that in its extended position. The adjacent links of the chain include interlocking, axially aligned projections for withstanding compressive as well as tensile loads.
