Duplicating system for a lathe

A lathe duplicating system comprising:

• means for supporting a pattern to be duplicated;
• table means for supporting a cutting tool;
• tool support means for holding a cutting tool, said support means including a base adapted to slidably engage said table means, follower means attached to and extending above said base and including a tip for engaging a pattern, a tool rod slidably engaging said base and extending outwardly therefrom, a cutting tool attached to an outer end of said tool rod, means for accurately positioning said tool rod relative to said base such that said cutting tool is vertically aligned with said follower tip;
• and
• insert guide means for engaging said cutting tool to prevent rotation thereof during a turning operation, said insert guide means being slidably positionable along said tool rod toward and away from said cutting tool whereby clearance may be provided to allow said cutting tool to be pivoted on said tool rod.

• table means for supporting a cutting tool;
• tool support means for holding a cutting tool, said support means including a base adapted to slidably engage said table means, follower means attached to and extending above said base and including a tip for engaging a pattern, a tool rod slidably engaging said base and extending outwardly therefrom, a cutting tool attached to an outer end of said tool rod, means for accurately positioning said tool rod relative to said base such that said cutting tool is vertically aligned with said follower tip;
• said cutting tool being pivotally attached to said tool rod and shaped to present either a substantially flat or a protruding rearward edge;
• and
• said system further comprising insert guide means for engaging said cutting tool to prevent rotation thereof during a turning operation, said guide means including a substantially flat front face positioned to engage said flat rearward edge of said cutting tool, a recess formed in said front face shaped to receive said protruding rearward edge of said cutting tool therein, an elongated slot formed therethrough, and a screw extending through said slot and threaded into said tool rod, such that said insert guide means slidably positionable on said tool rod, whereby said insert guide means may be retracted from engagement with said cutting tool to allow said cutting tool to be pivoted on said tool rod.

• means for supporting a cutting tool;
• tool support means for holding a cutting tool, said support means including a base, follower means attached to and extending above said base for engaging a pattern, a tool rod extending outwardly from said base, and a cutting tool pivotally attached to an outer end of said tool rod and shaped to present either a substantially flat or a protruding rearward edge;
• and
• insert guide means for engaging said cutting tool to prevent rotation thereof during a turning operation, said insert guide means being slidably positionable along said tool rod toward and away from said cutting tool whereby clearance may be provided to allow said cutting tool to be pivoted on said tool rod.

A lathe duplicating system comprising:

• means for supporting a pattern to be duplicated;
• table means for supporting a cutting tool;
• a base adapted to engage said table means in direct slidable contact therewith
• means defining a bore in said base,
• a tool rod slidably received in said bore and having an end thereof projecting outwardly therefrom;
• a cutting tool,
• means mounting said cutting tool on said outwardly projecting end of said tool rod;
• follower means mounted on said base above said tool rod in substantial alignment therewith;
• a follower tip mounted on an outer end of said follower means;
• and
• means projecting into said bore and engaging said tool rod at a predetermined position therealong and vertically aligning said follower tip and said cutting tool.

A lathe duplicating system comprising:

• means for supporting a pattern to be duplicated;
• table means for supporting a cutting tool;
• a base adapted slidably to engage said table means,
• means defining a bore in said base,
• a substantially cylindrical tool rod slidably received in said bore and having an end thereof projecting outwardly therefrom;
• a cutting tool,
• means mounting said cutting tool on said outwardly projecting end of said tool rod;
• follower means mounted on said base above said tool rod in substantial alignment therewith;
• a follower tip mounted on an outer end of said follower means;
• and
• a pointed screw received in a threaded bore intersecting said tool rod receiving bore;
• said screw projecting into said tool rod receiving bore and engaging said tool rod at a circumferential groove formed in said tool rod at a predetermined position therealong and vertically aligning said follower tip and said cutting tool.
