Abstract
An apparatus including a cylindrical body defined by forward and rear threaded end portions to receive a respective forward and rear collar. The forward collar is cooperative with pivotally mounted wedge plates that cooperate with the forward collar to direct associated presser feet into engagement with an associated workpiece to coaxially clamp the workpiece internally of the cylindrical body. The rear collar includes an internally threaded component for cooperation with the rear threads and a radially aligned cutter blade that is directed overlying the workpiece to effect cutting of the workpiece during rotation of the rear collar relative to the workpiece while clamped within the cylindrical body.
Claims6
A hand lathe apparatus comprising,
- an elongate longitudinally aligned cylindrical body, the cylindrical body including a through-extending bore defined by a coaxially aligned interior cylindrical surface, and
- the cylindrical body including a forward end and a rear end, the forward end and the rear end each including a respective forward thread and rear thread each respectively formed in surrounding relationship relative to the cylindrical body, and
- a forward collar mounted about the forward threads, and
- a rear collar mounted about the rear threads, and
- clamping means mounted through the cylindrical body for selective clamping of a workpiece directed through the cylindrical body, wherein the forward collar is cooperative with the clamping means to effect clamping of the workpiece, and
- wherein the rear collar is threadedly mounted about the rear threads to effect profiling of the workpiece mounted within the cylindrical body, and
- wherein the clamping means includes a series of wedge plates, the wedge plates each positioned at an equal spacing relative to the forward end of the cylindrical body, and each received within a "T" shaped slot directed through the cylindrical body, and each wedge plate including a "U" shaped presser foot pivotally mounted adjacent a rear end of each wedge plate, and each wedge plate including a forward axle, the forward axle orthogonally aligned relative to an axis defined by the cylindrical body and mounted within the cylindrical body.
