Abstract

615,399. Angular bending. DARD, L. Aug. 12, 1946, No. 23872. Convention date, June 6. [Class 83 (iv)] Apparatus for bending tubes &c. comprises a horizontal hydraulic jack 1 with vertical pump 6 actuated by a hand-lever 13. A head 27 adjustable about the axis of the jack overhangs a bench B and carries bending rollers in lugs 28 or in bearing holes which co-operate with a detachable head on the ram to effect bending. The hydraulic cylinder is fitted with a release valve 21 and is restored after release of pressure by a spring connected between the ram and the casing.
