Abstract
The invention provides a taper tool, including a movable sleeve that has flanges with inclined surfaces for use as hand-holds. The sleeve rides on bearings, which are mounted in recesses out of the user's way. A spring-loaded wireform retainer secures the bearings in their respective recesses. The retainers include quick-change tabs that hold the retainers in a servicing position that permits the bearings to be easily removed and replaced. The taper tool also includes a spool mounting assembly having a guard rod that swings out and away from a tape spool for facilitating replenishment of the tape. When the guard rod is in the closed position, it is secured by a detent located on the tape spool spindle. The spool mounting assembly includes a base, a tape spool, a spindle, a guard rod and an end protector having rounded, grippable exterior edges.
