Squaring machine for various sized tubes

A tube squaring machine comprising in combination;

• a housing having a first end,
• a rotatable shaft extending from said first end of said housing, said shaft having an axis
• feed means for selectively axially extending and retracting said rotatable shaft,
• a first retainer having a first retainer body having a first end and a second end,
• attachment means on said first end of said first retainer body for removably attaching said first retainer to said first end of said housing,
• first grasping means on said second end of said first retainer body, said first grasping means for grasping a cylindrical object having a first range of diameters which can be grasped thereby,
• said first retainer body having a cantilevered axially extending substantially C-shaped mounting portion defining a semi-cylindrical section forming an open area for viewing the tube, the retainer body further having a midsection with an arcuate cross-sectional shape where said cross-section is taken perpendicular to said axis of said shaft when said first retainer is attached to said first end of said housing,
• a second retainer having a second retainer body having a first end and a second end,
• attachment means on said first end of said second retainer body for removably attaching said second retainer to said first end of said housing,
• second grasping means on said second end of said second retainer body, said second grasping means for grasping a cylindrical object having a second range of diameters which can be grasped thereby, where said second range of diameters is different from said first range of diameters, and
• said second retainer body having a cantilevered axially extending substantially C-shaped mounting portion defining a semi-cylindrical section forming an open window area for viewing the tube, the retainer body further having a midsection with an arcuate cross-sectional shape where said cross-section is taken perpendicular to said axis of said shaft when said second retainer is attached to said first end of said housing means for retaining a tool on said rotatable shaft.

A tube squaring machine comprising in combination,

• a housing having a first end, a second end, and a tubular section between said first end and said second end,
• a drive member rotatable within said housing,
• a shaft axially slidable relative to said drive member, said shaft having a first end,
• a feed screw having a threaded cylindrical outer surface, said feed screw rotatable in said housing,
• a cap fitted over said first end of said housing, said cap fixed to said feed screw for movement therewith,
• said feed screw entirely enclosed in said housing,
• means for locking said feed screw against axial movement within said housing,
• a feed ring axially movable within said housing,
• means for locking said feed ring against rotation within said housing,
• first attachment means for rotatably attaching said shaft to said feed ring, said first attachment means extending from an end of said shaft,
• said feed screw having an axial opening at an end thereof for receiving at least a portion of said attachment means,
• said feed ring having a cylindrical inner surface with threads along a portion thereof,
• said threads of said feed screw engaged with said threads of said feed ring, and
• a first retainer having a first retainer body having a first end and a second end,
• a second attachment means on said first end of said first retainer body for removably attaching said first retainer to said first end of said housing,
• first grasping means on said second end of said first retainer body, said first grasping means for grasping a cylindrical object having a first range of diameters which can be grasped thereby,
• said first retainer body having a cantilevered axially extending substantially C-shaped mounting portion defining a semi-cylindrical section forming an open window area for viewing the tube, the retainer body further having a midsection with an arcuate cross-sectional shape where said cross-section is taken perpendicular to said axis of said shaft when said first retainer is attached to said first end of said housing,
• a second retainer having a second retainer body having a first end and a second end,
• third attachment means on said first end of said second retainer body for removably attaching said second retainer to said first end of said housing,
• second grasping means on said second end of said second retainer body, said second grasping means for grasping a cylindrical object having a second range of diameters which can be grasped thereby, where said second range of diameters if different from said first range of diameters, and
• said second retainer body having a cantilevered axially extending substantially C-shaped mounting portion defining a semi-cylindrical section forming an open window area for viewing the tube, the retainer body further having a midsection with an arcuate cross-sectional shape where said cross-section is taken perpendicular to said axis of said shaft when said second retainer is attached to said first end of said housing means for retaining a tool on said rotatable shaft.
