Abstract
Abstract Apparatus for cleaning the interior of a tube comprises a hose which has a jet producing head at one end thereof and which is connected to a supply of pressurized water at its other end. The hose is wound on a reel which has a drive mechanism, such as a motor for rotating the reel in either direction to wind and unwind hose on the reel. The apparatus also includes a housing within which the jet producing head can be accommodated and from which the head can be ejected.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
Cleaning apparatus for cleaning the interior of a tube or tubes, said apparatus comprising a hose having at one end thereof a jet producing head, a reel on which said hose is wound, drive means for rotating the reel to either unwind hose therefrom or wind hose onto the reel, a hand holdable housing having a barrel in which said head can be accommodated and from which the head can be ejected along a tube to be cleaned, the hose, when said head has been ejected, passing through said barrel, first and second switch means carried by said housing, actuation of said first switch means causing said drive means to rotate the reel in one direction and actuation of said second switch means causing said reel to rotate in the opposite direction, and means for supply water under pressure to said hose.
Claim 2
Dependent Claim
142 words
Cleaning apparatus for cleaning the interior of a tube or tubes, said apparatus comprising a hose having at one end thereof a jet producing head, a reel on which said hose is wound, drive means for rotating the reel to either unwind hose therefrom or wind hose onto the reel, a hand holdable housing having a barrel in which said head can be accommodated and from which the head can be ejected along a tube to be cleaned, the hose, when said head has been ejected, passing through said barrel, first and second switch means carried by said housing, actuation of said first switch means causing said drive means to rotate the reel in one direction and actuation of said second switch means causing said reel to rotate in the opposite direction, and means for supply water under pressure to said hose.
Claim 3
Dependent Claim
14 words
Apparatus as claimed in claim 1 wherein said drive means is a hydrostatic motor.
Claim 4
Dependent Claim
56 words
Apparatus as claimed in claim 1 wherein said first switch means is actuable by said head to cause said drive means to rotate the reel in the one direction, and said second switch means is actuable by a stop carried by the hose to cause said drive means to rotate the reel in the opposite direction.
Claim 5
Dependent Claim
21 words
Apparatus as claimed in claim 3 including a manually operable third switch, actuation of which inhibits operation of the drive means.
Claim 6
Dependent Claim
