Abstract

An apparatus for cleaning drains has a cable having a length and a first width and an extension disposed upon the first width of the cable to create a second width of the cable. A guide allows the length of the cable to pass therethrough but the second width whereby the cable will stop passing through the guide in a given direction if the second width contacts the guide.

Claims (24)

1. A drain cleaner comprising:

a drum for holding a cable and having a center of gravity,

a frame for rotatably holding said drum,

a handle disposed directly below said center of gravity of said drum such that a user may hold said drum without strain upon a users wrist,

said cable having a length and a first width,

an extension disposed upon said first width of said cable to create a second width of the cable,

a guide through which said length of said cable may pass therethrough but not said second width whereby said cable will stop passing through said guide in a given direction if said extension contacts said guide.

2. The apparatus of claim 1 wherein said guide at least partially surrounds said cable and has a diameter greater than said first width.

3. The apparatus of claim 1 wherein said second width is greater than said first width.

4. The apparatus of claim 1 wherein said guide is comprised of a plurality of fingers said fingers defining at least a partial surround having an internal dimension that allows said first width of said cable to pass therethrough but not said second width.

5. The apparatus of claim 4 wherein said fingers have a curved portion to form said guide and prevent said second width from passing therethrough.

6. A drain cleaner comprising:

a drum holding a cable and having a center of gravity,

a frame for rotatably holding said drum,

a handle disposed directly below said center of gravity such that a user may hold said drum without strain upon a users wrist,

said cable having a length and a first width.

7. The drain cleaner of claim 6 wherein said cable further comprises:

an extension disposed upon said first width of said cable to create a second width of the cable,

a guide disposed within said frame through which said length of said cable may pass therethrough but not said second width whereby said cable will stop passing through said guide as said cable exits said drum if said second width contacts said guide.

8. The apparatus of claim 7 wherein said guide at least partially surrounds said cable and has a diameter greater than said first width.

9. The apparatus of claim 7 wherein said second width is greater than said first width.

10. The apparatus of claim 7 wherein said guide is comprised of a plurality of fingers said fingers defining at least a partial surround having an internal dimension that allows said first width of said cable to pass therethrough but not said second width.

11. The apparatus of claim 10 wherein said fingers have a curved portion to form said guide and prevent said second width from passing therethrough.

12. The apparatus of claim 7 wherein said second width is defined by a lug.
