Hoisting Apparatus.

Description: 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.
