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.

Abstract:

The chuck assembly comprises: a chuck body having an outer end portion, an outer periphery and a central axial bore extending at least part way therethrough; a nose collar mounted on the outer end portion of the chuck body; structure for mounting the chuck body onto the outer end of a shaft of a powered drive mechanism; the outer end portion of the chuck body having at least one radially extending bore therein which extends from the outer periphery of the chuck body inwardly to an opening which opens to the central bore and which has a diameter less than the diameter of the radial bore; at least one ball or detent in the at least one radial bore; urging mechanism for urging the ball or detent into the radial bore and part way through the opening; releasing mechanism for allowing the ball or detent to move radially outwardly in the radial bore and away from the opening; and structure in the central bore for engaging a tool shank and preventing rotation of the tool shank relative to the chuck body.

US Classification:

279137

Abstract:

The elongate rod shaped non-impact and non percussion drilling tool comprises: a non-impact and non-percussion drilling tool or implement formation at an outer end of the shank, a portion of the shank having a polygonal cross section at a location on the shank other than at an inner end of the shank, an annular groove in the shank which is only wide enough to receive a detent to prevent axial movement of the tool when it is received in a snap-in chuck assembly and a spline formation at an inner end of the shank. The chuck assembly includes either a polygonal drive structure in a center bore of the chuck assembly or a rotatable nose collar or an axially movable nose collar whereby a tool received in the center bore is held by friction in the polygonal drive structure or by a rotatable movement or an axial movement of the nose collar.
