ABSTRACT:
A replaceable spindle locking system for a power tool enables an operator to replace a lock member without disassembling the tool. An externally-accessible retaining member, such as a washer, is trapped between a ledge located in a housing recess and a shoulder formed on the lock member, which is normally spring-biased out of engagement with a driven member. The coaction of these elements simultaneously and releasably normally retains both the lock member and the retaining member connected to the housing. When it is desired to replace the lock member, the operator depresses the lock member against the urging of the spring until the lock member is out of retaining engagement with the retaining member. Then the retaining member is slideably moved out of engagement with the lock member, thereby allowing the operator to quickly remove it.
