Claims
- 1. A tube cleaning apparatus comprising a portable housing, a reversible drive motor mounted within the housing, an elongated cable having a brash assembly affixed thereto for cleaning the interior surfaces of tubes, a protective casing covering the cable, means affixed to the housing powered by said drive motor for engaging the cable intermediate its ends and for propelling the cable and brush assembly into and out of tubes for cleaning the interior surfaces of the tubes, and a portable control handle having a passageway for positioning the cable and brush assembly at each tube to be cleaned, and the control handle having means for signalling the propelling means to propel the cable and brush assembly into and out of tubes and to stop movement of the cable and brush assembly.
- 2. A tube cleaning apparatus as defined in claim 1 in which the control handle issues pneumatic signals to control the cable and brash assembly.
- 3. A tube cleaning apparatus comprising an elongated cable having a brush assembly affixed thereto for cleaning the interior surfaces of tubes, a protective casing covering the cable, a power console, a reversible drive motor mounted within the power console, air switch means for operating the motor in forward and reverse modes, means affixed to the power console driven by the drive motor for engaging the cable intermediate its ends and for propelling the cable and brush assembly into and out of tubes for cleaning the interior surfaces of the tubes, and a portable control handle having a passageway for positioning the cable and brush assembly at each tube to be cleaned, and the control handle having means for signalling the air switch means to propel the cable and brush assembly into and out of tubes and to stop movement of the cable and brush assembly.
- 4. A tube cleaning apparatus as defined in claim 3 in which the control handle includes means for generating air pulses.
- 5. A tube cleaning apparatus as defined in claim 4 in which the means for generating air pulses comprises forward and reverse air bellows fitted into the control handle, and in which the control handle includes a trigger for selectively actuating the means for generating air pulses for moving the brush assembly.
- 6. A tube cleaning apparatus as defined in claim 3 which further includes an arresting device for stopping forward progress of the cable and brush assembly.
- 7. A tube cleaning apparatus comprising a portable housing, an elongated cable having a brush assembly affixed thereto for cleaning the interior surfaces of tubes, a protective casing covering the cable, a reversible drive motor within the portable housing, air switch means for operating the motor in forward and reverse modes, means affixed to the housing driven by the drive motor for engaging the cable intermediate its ends and for propelling the cable and brush assembly into and out of tubes for cleaning the interior surfaces of the tubes, an air supply providing control air, air links connecting the air supply to the air switch means, a portable control handle having a passageway for positioning the cable and brush assembly at each tube to be cleaned, and air links to the control handle for signalling the air switch means to propel the cable and brush assembly into and out of tubes and to stop movement of the cable and brush assembly.
