Hoisting Apparatus. (open access)

Hoisting Apparatus.

Patent for improvements in hoisting apparatus by “employing two cables and two sheaves that one cable and one sheave operate to elevate the weight or object in an approximately-vertical plane, so as to avoid contact with any side obstruction, while the secondary cable can subsequently be slackened sufficiently to permit the traveling sheave of the hoisting-cable to run off in a lateral direction and carry with it the sheave of the slackened secondary cable, for the purpose of transferring the object or weight to a desired position out of the line of the approximately-vertical direction first given to it.” (Page 2, lines 4-16) Illustration is included.
