Abstract
195,278. Tarbet, D. M. April 11, 1922. Addition to 182,606. Angular bending and carving; dies; mandrels. -In bending copper and like pipes by a recessed die c having outwardly-extending jaws, which alone engage the pipe at nearly diametrically opposite points, as described in the parent Specification, a flexible tubular or cylindrical flexible mandrel f is inserted in the pipe prior to bending, when effecting sharp bends or acting on pipes with comparatively thin walls. The mandrel may consist of a helical spring or a flexible metallic tube and its ends may be formed with eyes. To withdraw the mandrel after bending it is first twisted at one end to decrease its diameter. In the apparatus shown, the die is attached to an hydraulically-operated piston b.
