Abstract:

Apparatus for taking dents, bends, and crushed areas out of siphon tubes and restoring the tubes to their original shape, the apparatus comprising a pair of end plugs, a pair of tube vises, a pair of screw clamps, and an hydraulic pump. The hydraulic pump has an inlet from a water source, such as a common garden hose, and an outlet to one of the end plugs. The end plugs each have an internal fluid passage for fluid communication with the interior of the tube to be restored. A second end plug is attached to the other end of the tube; the second plug terminating in a draincock for ridding the system of any air. The end plugs are held in sealed engagement with the ends of the tube to be restored by means of screw clamps which are anchored to the tube by means of the vises. To restore a crushed tube, water is allowed to fill the system through the inlet of the hydraulic pump. The draincock is then closed, sealing the system.
