Abstract
A coupling between the piston and cylinder controlling and actuating member and the bending head of a portable pipe bending machine comprising a collar (5) made up of two half collars (5', 5") with concavities complementary with the side wall of the cylinder (3), which are removably joined (6, 6') to each other to clamp the cylinder itself, one of them (5') being rigidly joined (6, 6') to the bending head (1), a coupling which is desired further comprises structure for preventing the axial displacement of the collar (5) upon the cylinder (3), particularly a groove (9', 9") on the collar and a complementary ridge (9) on the cylinder (3).
Claims7
A portable pipe bending apparatus having a piston and cylinder controlling an actuating member, said apparatus also comprising a working head, the working head being integral with a collar made up of two half collars which together removably clamp between them the cylinder, whereby loosening of the two half collars from the cylinder enables the two half collars and with them the working head to be rotated about the cylinder to a convenient working position.
