ABSTRACT:
A spool having an elongated barrel has a strap supported at one end at a bottom flange on the barrel with the strap passing upwardly therethrough out of the upper end thereof. The strap is removably attached to the bottom flange. A handle is affixed to the strap portion which extends beyond the upper end of the spool. A rigid frame having an upright portion is affixed to a base supported by casters. The frame has a member rigidly affixed to and transversely extending from the upper end of the upright portion which overhangs the spool. A lever having a transverse portion near one end is pivotally connected at the distal end of the transverse portion to the frame member. An arm is pivotably secured at one end to the upright portion and at the other end is engageable with the spool handle. A link is pivotably connected between said arm and the transverse portion to provide a toggle linkage. A downward force applied to the end of the lever serves to lift the arm and the spool by means of the engagement between the arm and the handle whereas an upward force lowers the spool. The toggle linkage serves to lock the spool in the lifted position.
