Abstract
A compact auger-type cleanout tool for use in clearing stoppages in waste pipes associated with sinks, bathtubs, water closets and the like in which any required number of additional lengths of plumbers' snake can be added to the device without removing the snake from the line. The device includes one or more telescoping tubular housings and a drive member associated therewith adapted to transmit rotary movement to the plumbers' snake. The initial length of snake fed into the line includes a uniquely designed coupling leader to which additional lengths of snake can readily be coupled making the device suitable for cleanout of very long runs of waste pipe.
Claims10
A waste pipe cleanout device comprising:
- (a) a first elongated casing member;
- (b) an elongated drive member telescopically receivable in said first casing member;
- (c) interengaging means affixed to one end of said drive member for rotating said member;
- (d) a coupling leader connected to the other end of said drive member and adapted to project a limited distance from said casing member when said drive member is fully telescopically received therewithin, said coupling leader being rotatable with said drive member and having first interlocking means at its free end for removably interlocking together therewith a length of flexible coiled spring;
- and
- (e) a length of flexible coiled spring having at one end thereof a second interlocking means adapted to mate with said first interlocking means whereby rotation of said drive member causes rotation of said coiled spring.
A waste pipe cleanout device comprising:
- (a) a first elongated casing member;
- (b) an elongated drive member telescopically receivable in said first casing member;
- (c) a second elongated casing member adapted to telescopically receive said first elongated casing member;
- (d) a crank handle affixed to one end of said drive member for rotating said member;
- (e) a coupling leader connected to the other end of said drive member and adapted to project a limited distance from said first casing member when said drive member is fully telescopically received therewithin, said coupling leader being rotatable with said drive member and having first interlocking means of its free end for removably interlocking together therewith a length of flexible coiled spring;
- and
- (f) a length of flexible coiled spring having at one end thereof a second interlocking means adapted to mate with said first interlocking means whereby rotation of said drive member causes rotation of said coiled spring, said coiled spring having a length substantially equal to the combined length of said first and second casing members.
A waste pipe cleanout device comprising:
- (a) a first elongated casing member;
- (b) an elongated drive member telescopically receivable in said first casing member, said drive member being hollow and having proximate each end thereof leader connecting means;
- (c) a second elongated casing member adapted to telescopically receive said first elongated casing member;
- (d) a crank handle affixed to said drive member for rotating said member;
- (e) a coupling leader having at a first end connecting means adapted to mateable engage said leader connecting means whereby said coupling leader is rotatable with said drive member and having at its second end spring interlocking means for removably interlocking together therewith a length of flexible coiled spring;
- and
- (f) a length of flexible coiled spring having at one end thereof interlocking means adapted to mate with said spring interlocking means whereby rotation of said drive member causes rotation of said coiled spring, said coiled spring having a length substantially equal to the combined length of said first casing member, said second casing member and said hollow drive member.
