International Classification:

G01B 520

US Classification:

33507, 33200

Abstract:

A tracer is provided for tracing a lens mount of an eyeglass frame, a lens or a lens pattern. The tracer comprises an object engager and an actuator. The object engager is adapted to engage the lens mount, the lens or the lens pattern. The actuator is adapted to move the object engager into contact with and then along the lens mount, the lens or the lens pattern in such a way that during movement therealong, the object engager remains against the object being traced even when the shape thereof includes high wrap. Preferably, the tracer has a shift mechanism adapted to shift the object engager from alignment with the lens mount to alignment with a second lens mount of the eyeglass frame. The actuator preferably is further adapted to trace the second lens mount in substantially the same way as the first. The actuator further includes a rotator and a pivot mechanism. The rotator is adapted to rotate the object engager along the object being traced.

International Classification:

B23P 1900

US Classification:

29758

Abstract:

A portable hand-held battery-powered crimping tool includes a gear housing containing a through bore receiving a driven gear having a crank arm that is connected by a drive link with the common pivot axis of a toggle device that pivots a pair of crimping jaws from an open released position toward a crimping position. The gear is driven by a reversible direct-current motor that is supported on the hand-held handle together with a battery pack. A releasable overrunning clutch is operated by a push button on the handle to disengage the motor drive from the drive link, whereupon the crimping jaws are pivoted toward the open released position by a biasing spring.
