Abstract

Claims (50)

1. A sewer cleaning machine comprising:

a frame;

a drum supported by the frame, the drum including a cable that is selectively extendable out of the drum; and

a motor supported by the frame and coupled to the drum, the motor operable to rotate the drum;

wherein the frame is moveable between a first position, in which the drum is supported by the frame off of a surface, and a second position, in which the drum contacts the surface,

wherein the frame includes a kickstand that is pivotable relative to the drum between the first position, in which the kickstand is lowered and configured to contact the surface, and the second position, in which the kickstand is raised and configured to be spaced apart from the surface.

2. The sewer cleaning machine of claim 1 , wherein the frame includes legs configured to support the sewer cleaning machine on the surface.

3. The sewer cleaning machine of claim 2 , wherein the legs are adjustable between the first position, in which the legs are moved to support the drum off of the surface, and the second position, in which the legs are moved so the drum engages the surface.

4. The sewer cleaning machine of claim 1 , wherein the frame includes a telescopic leg adjustable between the first position, in which the telescopic leg is extended and configured to contact the surface, and the second position, in which the telescopic leg is retracted and configured to be spaced apart from the surface.

5. The sewer cleaning machine of claim 1 , wherein the drum is rotated by the motor relative to the frame while in the second position.

6. The sewer cleaning machine of claim 1 , wherein the frame includes a handle to control the sewer cleaning machine while in the second position to move the drum along the surface.

7. A sewer cleaning machine comprising:

a frame;

a handle slidably connected to the frame;

a drum supported by the frame, the drum including a cable that is selectively extendable out of the drum; and

a motor supported by the frame and coupled to the drum, the motor operable to rotate the drum;

wherein the handle is slidable relative to the frame between a first position, in which the drum is supported by the frame off of a surface, and a second position, in which the drum contacts the surface,

wherein the frame includes a slide member that is coupled to the handle and a main body pivotably coupled to the slide member, and wherein the main body supports the drum.

8. The sewer cleaning machine of claim 7 , wherein the main body includes a channel that receives a portion of the handle, and wherein the portion of the handle is slidable within the channel between the first position and the second position.

9. The sewer cleaning machine of claim 8 , wherein

the handle includes a first leg rotatably connected to a second leg,

the first leg is coupled to the slide member, and

the second leg is slidably received in the channel.

10. The sewer cleaning machine of claim 9 , wherein

the main body includes a first portion pivotably connected to the slide member and a second portion including the channel,

the first portion and the second portion form an L-shape, and

the second portion is configured to engage the surface while the handle is in the first position.

11. The sewer cleaning machine of claim 10 , wherein

the first leg is rotatably connected to the second leg about a hinge,

a corner of the main body between the first portion and the second portion is spaced apart from the hinge when the handle in the first position, and

the corner of the main body is adjacent the hinge while the handle in the second position.

12. The sewer cleaning machine of claim 10 , wherein the main body includes a rod member coupled to the first portion and the second portion, and wherein the rod member rotatably supports the drum.

13. A sewer cleaning machine comprising:

a frame;

a handle slidably connected to the frame;

a drum supported by the frame, the drum including a cable that is selectively extendable out of the drum; and

a motor supported by the frame and coupled to the drum, the motor operable to rotate the drum;

wherein the handle is slidable relative to the frame between a first position, in which the drum is supported by the frame off of a surface, and a second position, in which the drum contacts the surface,

wherein the drum is rotated by the motor while the handle is in the second position to move the sewer cleaning machine along the surface.

14. A sewer cleaning machine comprising:

a shroud;

a drum supported by the shroud, the drum including a cable that is selectively extendable out of the drum; and

a motor supported by the shroud and coupled to the drum, the motor operable to rotate the drum;

wherein the shroud is rotatable relative to the drum in a first direction into a first position,

in which the drum is supported by the shroud off of a surface, and

wherein the shroud is rotatable relative to the drum in a second direction opposite the first direction into a second position, in which the drum contacts the surface.

15. The sewer cleaning machine of claim 14 , further comprising a handle extending from the shroud, wherein the handle is rotatable with the shroud relative to the drum between the first position and the second position.

16. The sewer cleaning machine of claim 14 , wherein the shroud includes a stand, and wherein the stand is configured to contact the surface when the shroud is in the first position.

17. The sewer cleaning machine of claim 16 , wherein the stand includes a first leg and a second leg, and wherein the first leg and the second leg are configured to contact the surface when the shroud is in the first position.

18. The sewer cleaning machine of claim 14 , wherein the drum functions as a wheel to transport the sewer cleaning machine when the shroud is in the second position.
