a hand portable press fitting of pipe quality

摘要

A hand-portable press having hydraulically extendable shoe forming dies for swaging a pipe coupling into pipe joint formation with a contained pipe section. Each die is separately mounted for articulated movement on the inward end of a hydraulically moveable piston and is arcuate on its innermost face with which swaging is effected. Application of hydraulic pressure, by means of a portable hand pump, forces each piston and shoe die thereon inwardly until concentrically uniform swaging of a coupling into a pressure tight pipe joint with contained pipe is effected.
