ABSTRACT:
An instrument and tool honing mechanism in which a gear rack is mounted on and movable with a reciprocable bar, and a spindle having a pinion thereon is supported by a fixture in a transverse relationship to said bar with the pinion in engagement with the gear rack. A honing element is mounted on the spindle, and when the bar reciprocates, the rack creates a reciprocating movement in the spindle, and hence rotates the honing element on the spindle. The mechanism is preferably constructed as an attachment for a honing machine, and is capable of being readily mounted on and removed from the machine. The fixture preferably is pivoted to the rear of the reciprocable bar for angular movement from a position substantially horizontal to an elevated position where the pinion is disengaged from the gear rack. The honing element may be spherical or cylindrical shaped, and is normally mounted on a forwardly projecting end of the spindle where it can easily be used to recondition instruments and tools of the type normally used by dentists and doctors.
