Abstract
A tube cleaning tool for removal of hard deposits from the interior wall of a tube has a cylindrical body portion with an outer diameter, less than the inner diameter of the tube, a nose portion at one end and a tail portion at the other end, with a plurality of spaced freewheeling cutting wheels provided on the body portion which extend outwardly therefrom, the cutting wheels at least partially contained within the confines of the cylindrical body portion and rotatable about an axis transverse the longitudinal axis of the cylindrical body portion.
Claims20
A tube cleaning tool for loosening of hard deposits collected on an interior wall of a tube comprising:
- a cylindrical body portion having an outer diameter, less than the inner diameter of said tube, and a longitudinal axis;
- a nose portion on one end of said cylindrical body portion;
- a tail portion on the other end of said cylindrical body portion;
- and
- a plurality of spaced freewheeling cutting wheels provided in and extending radially outwardly from said cylindrical body portion, said cutting wheels being at least partially contained within the confines of said cylindrical body, each said cutting wheel rotatable about an axis that is transverse to the longitudinal axis of said cylindrical body portion and in a fixed position relative to said longitudinal axis.
A tube cleaning tool as defined in claim wherein a major portion of said cutting wheels are contained within the confines of said cylindrical body.
A tube cleaning tool as defined in claim wherein said tail portion has thereon an outwardly and rearwardly extending flexible skirt.
A tube cleaning tool as defined in claim wherein a first plurality of said spaced cutting wheels are, provided adjacent said nose portion of said cylindrical body and a second plurality of spaced cutting wheels are provided adjacent said tail portion of said cylindrical body.
A tube cleaning tool for loosening of hard deposits collected o an interior wall of a tube comprising:
- a cylindrical body portion, having an outer diameter less than the inner diameter of said tube and a longitudinal axis, comprising a cylindrical member having a recess in one end thereof forming an encircling wall about said recess and wherein spaced slots are formed in said encircling wall for positioning of cutting wheels therein and at least partially within the confines of said cylindrical body,
- a nose portion on one end of said cylindrical body portion, said nose portion formed as a truncated cone having a base with a rearwardly extending tubular member provided thereon, said rearwardly extending tubular member having an outer diameter which cooperates with an inner diameter of said encircling wall of the recess of said cylindrical member and channels in said tubular member which align with the slots in said encircling wall, said tubular member engaged in the recess of said cylindrical member;
- a tail portion on the other end of said cylindrical body portion having an outwardly and rearwardly extending flexible skirt thereon;
- and
- a plurality of spaced freewheeling cutting wheels provided in and extending radially outwardly, through said spaced slots, from said cylindrical body portion, said cutting wheels being at least partially contained within the confines of said cylindrical body, each said cutting wheel rotatable about an axis that is transverse to the longitudinal axis of said cylindrical body portion.
