Conduit reamer tool assembly
First Claim
1. A conduit reamer assembly comprising:
- a spindle having a main body portion, a distal end and a proximal end;
drive structure on said spindle for mating with corresponding drive structure in a rotatable drive structure in or on which said conduit reamer assembly is mounted;
a conduit reamer mounted on said spindle and comprising at least two stepped cylindrical sections including a first cylindrical section and a second larger diameter section;
a first generally hook-shape formation extending radially outwardly from said first cylindrical section and defining a U-shaped space between said cylindrical section and an outer axially finger of said first formation;
said second cylindrical section having a second generally hook-shape formation extending generally radially outwardly from said second cylindrical section and defining a U-shaped space between said second cylindrical section and an outer axially extending finger of said second formation; and
said conduit reamer having means for fixing said reamer against rotation on said spindle and said U-shaped spaces being adapted to be received over a cut end of a piece of conduit for engaging the cut end as said conduit reamer is rotated.

Abstract
The conduit reamer assembly comprises: a spindle having a main body portion, a distal end and a proximal end; drive structure on the spindle for mating with corresponding drive structure in a rotatable drive structure in or on which the conduit reamer assembly is mounted; a conduit reamer mounted on the spindle and comprising at least two stepped cylindrical sections including a first cylindrical section and a second larger diameter section; a first plate-like member extending radially outwardly of the first cylindrical section and having a generally hook-shape defining a U-shaped space between the cylindrical section and an outer axially extending finger of the plate-like member; the second cylindrical section having a second plate-like member extending generally radially outwardly from the second cylindrical section and defining a U-shaped space between the second cylindrical section and an outer axially extending finger; and the conduit reamer being fixed against rotation on the spindle and the U-shaped spaces being adapted to be received over a cut end of a piece of conduit for engaging the cut end as the conduit reamer is rotated. The conduit reamer assembly can further include a tool magazine including a body having a throughbore which is received over the spindle and behind the conduit reamer. The body has a rearwardly facing surface and the tool magazine includes at least one bore, socket or hole extending into the tool magazine from the back surface thereof for receiving and storing a tool.
