Abstract: To eliminate the need for using a hand wrench or another hand tool to remove lock nuts, screws, or other fasteners, to be able thereafter to remove a circular saw blade from a powered hand or table saw, this quick change mechanism is installed on the shaft or arbor of the powered saw. There is a preassembly of: a splined and grooved circular saw blade holder; a complementary splined slide lock with upwardly extending spline finger, for axially sliding on the blade holder; an installation bolt passable down through this blade holder and this slide lock, having an axial spring receiving cavity in a tapered head, also having an allen wrench receiving cavity; a coiled spring to be received in this cavity; and a release button with depending spring legs terminating in feet for passing about this coiled spring and down alongside the blade holder, via grooves formed in the spline recesses of this blade holder.

Abstract: In one embodiment of this quick change mechanism, a narrow six spline hub is installed in the arbor hole of a circular saw blade or other disc tool heads such as grinders, sanders and buffers. This hub slides onto a matching splined drive shaft in which a narrow section of spline lands has been removed circumferentially to fit the width of the splined hub that is secured to the circular saw blade. A fifteen degree rotation of this splined blade hub on this shaft aligns all the lands and grooves, thus locking the hub relative the longitudinal axis of the drive shaft. To continue the locking, by locking the hub in rotation relative to the shaft, a splined sliding collar with spline land extensions, serving as locking fingers, is interposed into the spline grooves of the drive shaft and also the hub grooves. A blind longitudinal hole in the drive shaft contains a compression spring and an unthreaded bolt.
