Key duplication attachment device for rotary tool with profiled abrasive cutter

Abstract

A key grinding duplicating attachment that includes a base with upright bearing supports juxtaposed which supports a horizontal guide bar transporting control housing assembly. Said assembly movement being slidable on a horizontal axis, swingable upward and downward in contact with top edge of the keys. Base solid mount angled vise support uprights with clamping vises juxtaposed for specimen and blank keys. The said transporting control housing assembly supports a modulate direct output rotary tool high speed high torque motor or an equivalent, profiled abrasive key grinder arbor assembly, a juxtaposed profiled stylus in line. An effortless means to produce usable duplicated keys continually.

1 . A horizontal guide transporting housing body which includes through guide bar secured to uprights juxtaposed bearing support means said member having a hole near its upper ends allowing for swinging upward and downward contacting key top surface, also slide on a horizontal axis.  
     
     
         2 . Having a rotary tool power motor and/or high torque high speed power source, having an output shaft, a rotating cutting type cutter attached to an output means.  
     
     
         3 . A horizontal guide transporting housing body to fasten a rotary motor and or rotary motor tool.  
     
     
         4 . A duplicating profiled stylus attached to said transporting housing body means.  
     
     
         5 . A horizontal guide support bar slide incorporated in said transport housing means.  
     
     
         6 . Solid mount vise supports angled to uprights to rectangular base frame.  
     
     
         7 . Clamping vise devices attached to solid mount uprights for clamping keys.  
     
     
         8 . An actuating handle means being the rotary tool motor housing, attached to horizontal guide transporting housing, to force the rotating cutter into contact with blank key and a duplicating profiled stylus, in contact with specimen key.
