Claims
- 1. A wasteline cleanout tool of the character having an elongated coiled spring housed within a drum having a forward neck portion through which the coiled spring can be withdrawn and a rearward hub, said tool comprising:
- (a) a frame having a base, including first and second removable interconnected portions, a forward portion connected to said first portion of said base and a rearward portion connected to said second base portion;
- (b) feed means connected to said forward portion of said frame for removable engagement with the coiled spring to controllably withdraw the coiled spring from the drum thereof, said feed means including hub engaging means for releasable engagement with the rearward hub of the drum; and
- (c) frame supporting means for supporting said frame, said frame supporting means being movable about a fulcrum from a first position wherein said base of said frame extends substantially horizontally to a second position wherein said base extends angularly upwardly, said frame supporting means comprising a transport assembly having:
- (i) an upper portion including hand engaging means for engagement by the hands of the operator of the tool, a pair of downwardly extending tubular members connected to said hand engaging means, and a spring mounted within each of said downwardly extending members; and
- (ii) a lower portion including a pair of rearwardly extending legs, a pair of wheels rotatably carried by said rearwardly extending legs and a pair of upwardly extending legs telescopically receivable within said downwardly extending tubular members for engagement with said spring, whereby a downward pressure exerted on said hand engaging means will cause telescopic movement of said upwardly extending legs within said downwardly extending tubular member against the urging of said spring.
- 2. A wasteline cleanout tool of the character having an elongated coiled spring housed within a drum having a forward neck portion through which the coiled spring can be withdrawn and a rearward hub, said tool comprising:
- (a) a frame having a base, including first and second removably interconnected portions, a forward portion connected to said first portion of said base, and a rearward portion connected to said second base portion;
- (b) feed means connected to said forward portion of said frame for removable engagement with the coiled spring to controllably withdraw the coiled spring from the drum through the forward neck portion thereof;
- (c) drive means connected to said rearward portion of said frame for rotating said drum about the central axis thereof; and
- (d) frame supporting means for supporting said frame, said frame supporting means being movable about a fulcrum from a first position wherein said base of said frame extends substantially horizontally to a second position wherein said base extends angularly upwardly, said frame supporting means comprising a transport assembly having:
- (i) a lower portion including a pair of rearwardly extending legs, and a pair of upwardly extending legs;
- (ii) an upper portion including a pair of downwardly extending tubular members receivable over said upwardly extending legs of said lower portion, and biasing means for yieldably resisting upward movement of said pair of upwardly extending legs of said lower portion.
- 3. A wasteline cleanout tool as defined in claim 2, further including a pair of wheels rotatably carried by said rearwardly extending legs of said lower portion.
- 4. A wasteline cleanout tool as defined in claim 2, in which said upper portion further includes hand engaging means for engagement by the operator of the tool.
- 5. A wasteline cleanout tool as defined in claim 2 in which said upwardly extending legs of said lower portion are telescopically receivable within said tubular members of said upper portion and in which said biasing means comprise a pair of coiled springs mounted within said tubular members of said upper portion.
- 6. A ground supported wasteline cleanout tool of the character having an elongated coiled spring housed within a drum having a forward neck portion through which the coiled spring can be withdrawn and a rearward hub, said tool comprising:
- (a) a frame assembly including:
- (i) first and second removably interconnected base portions, said second base portion having a forward ground engaging extremity disposed proximate said first base portion and a rearward ground engaging extremity spaced apart from said first base portion;
- (ii) a forward frame portion connected to said first base portion; and
- (iii) a rearward frame portion connected to said second base portion, said rearward frame portion rotatably supporting the drum;
- (b) feed means connected to said forward frame portion for removable engagement with the coiled spring to controllably withdraw the coiled spring from the drum through the forward neck portion thereof;
- (c) drive means connected to said rearward frame portion for rotating said drum about the central axis thereof; and
- (d) frame supporting means for supporting said frame, and for normally maintaining said second base portion elevated relative to the ground substantially parallel thereto, said drum being removable from said second frame portion upon separation of said first and second base portions, and upon tilting said second base portion forwardly to move said forward ground engaging extremity into engagement with the ground, said frame supporting means also being movable about said rearward ground engaging extremity from a first position wherein said second base portion extends angularly upwardly to permit connection and disconnection of said first and second base portions.
- 7. A tool as defined in claim 6, in which said frame supporting means comprises a transport assembly having:
- (i) a lower portion including a pair of rearwardly extending legs and a pair of upwardly extending legs;
- (ii) an upper portion including a pair of downwardly extending tubular members telescopically receivable over said upwardly extending legs of said lower portion.
- 8. A wasteline cleanout tool as defined in claim 7, further including biasing means for yieldably resisting upward movement of said pair of upwardly extending legs of said lower portion.
- 9. A wasteline cleanout tool as defined in claim 8, in which said biasing means comprise a pair of coiled springs mounted within said tubular members of said upper portion.
