Abstract: This invention relates to dereeling apparatus for unreeling wire from a spool preferably disposed with the axis thereof upright. A first cylindrical shroud is adapted to be positioned coaxially over the spool in radially spaced relation therewith and with the upper end of the shroud disposed above the spool. A ring of multiple circumferentially spaced axially extending bristles of resilient material is provided on the upper end of the shroud. A second cylindrical shroud of larger diameter than the first and coaxially disposed to overlie the ring in radially spaced position is mounted on the upper end of the first shroud. The second shroud is provided with a cover having a centrally located aperture which receives a strand of wire being unreeled from the spool.

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.

Abstract: A spool barrel has flat sides which preferably are tapered from one end to the other. Rounded corners are formed between adjacent side edges. Each of the corners has a plurality of wire receiving ridges whereby the first or base layer of wire windings on the spool will nest in the grooves or channels between the ridges and be held thereby against axial movement on the spool barrel. A molded spool barrel having an integral molded lower flange has a molded upper flange removably attached to the upper barrel end.

Abstract: A pressure sensitive valve is mounted on the barrel of a magnet wire spool to be closed by wire wrapped on the barrel. Superatmospheric pressure is maintained internally of the barrel which is released upon opening of the valve by removal of the wire from the spool. A pressure-sensing device activates in response to such pressure release to provide a warning signal or suitable control function.
