ABSTRACT:
An apparatus for use in removing and replacing a grinding wheel of a portable industrial grinder of the type having an output shaft, a grinding wheel support sleeve on the shaft, a non-circular collar formed on the sleeve, and laterally extending handles. The apparatus includes an upstanding housing having a top wall with a slot formed therein. The slot is open at one end and is dimensioned to receive and engage the non-circular collar of the shaft support sleeve of the portable grinder with the grinding wheel being supported on the top wall. The housing is equipped with an opening in at least one side thereof to permit the portable grinder to be positioned in the housing below the slotted top wall. A grinding wheel clamp adapted to engage the grinding wheel when it is supported on the top wall of the housing is provided. The grinding wheel clamp has two fixed fingers which engage the periphery of the grinding wheel at circumferentially spaced locations thereon and a movable finger circumferentially spaced relative to the two fixed fingers. A support arm is provided which extends over the top wall of the housing and is pivotally mounted relative to the housing for rotation about a vertical axis. The grinding wheel clamp is pivotally connected to the support arm and is slidable along the length of a portion of the support arm. The grinding wheel clamp may be releasable locked at selected positions along the length of the portion of the support arm. The movable finger is pivotally mounted for movement at right angles to the direction of unloosening rotation of the grinding wheel so that the arm of which the finger is a part can be used both to clamp the grinding wheel and to rotate it to loosen it.
