Abstract

372,719. Portable angular benders. PETITIAUX, M., 16, Rue Notre-Dame, Toulouse, France. Feb. 16, 1932, No. 4574. Convention date, Feb. 26, 1931. [Class 83 (iv).] A portable threepoint tube-bender is actuated by a variable-throw handpump. A fluidoperated plunger 6 returned by a spring 7 sliding in the cylinder 9 co-operates with rollers 3 mounted on brackets 4 to bend a tube 2, the pressure required to actuate the plunger 6 being supplied by a vertically arranged pump 11, driven through a connecting rod 13 by the lever handle 26. The stroke of the pump is varied by sliding the block 14 along the crank 15, notches being provided on a graduated bar 19 to give the throw required for bending pipes of various diameters. A pipe vice 22 is carried by the cylinder 9 which has a casing 10 providing a reservoir for fluid.
