Automatic abrasive sleeve tightening means and quick release system for an oscillating spindle sander

Abstract

A quick release system for an oscillating spindle sander comprises a linearly elongated shaft inserted and housed within a cavity of a sanding drum. A top washer comprising a central aperture and a pair of downwardly projecting prongs aligned about a circumference of the central aperture and insertable into notches formed within the top of the shaft. A pin assembly is insertable into the shaft to impinge the top washer with the sanding drum, thereby compressing an abrasive sanding sleeve placed onto said sanding drum and permitting sanding of an object. The pin assembly may be released and removed from the shaft, permitting removal of the top washer. Upon removal of the top washer, the abrasive sanding sleeve may be removed and disposed of, or inverted so as to use the unused portion of the sanding sleeve, and thus extending the useful life of the sleeve.
