Sheet squaring apparatus

Claim 1

A sheet metal squaring apparatus comprising in combination: support means providing a pivot means on which a carrier means may be attached and pivoted; a carrier means including a base support structure receivable of a flat surface of a metal sheet bottom face for support of such metal sheet; the carrier means further including two separate flat-faced sides each extending uprightly from a plane in which the carrier means base support structure extends, and each flat-faced side extending laterally in a direction substantially perpendicular to the plane of the other flat-faced side; said carrier means being positioned and pivotably attached to the pivot means such that the base support structure is pivotable between alternate horizontal and substantially upright plane positions and such that when pivoted into the substantially upright position of the base support structure, the perpendicular planes are both pointed substantially angularly downwardly; clamp means mounted on the carrier means at a point such that stacked metal sheets are firmly clampable between the clamping means and the base support structure, the clamping means being adjustably clampable and releasable of a stack of metal sheets supported on the base support structure; and vibrator means mounted on the carrier means for selectively vibrating simultaneously the two separate flat-faced sides, the vibrator means including two separate vibrators one mounted fixedly on one of the two separate flatfaced sides and the remaining other vibrator mounted fixedly on the remaining other flat-faced side, and the vibrator means further including a micro-switch means for automatically activating the two separate vibrators when the carrier means is pivoted such that the base support structure extends in the substantially upright plane, and for automatically deactivating the vibration when the carrier means is pivoted to remove the base support structure from the substantially upright plane state.
