Abstract

18,986. B a l - lard, F. A. Sept. 3. Bending.-An apparatus for bending gas pipes &c. has a standard 1 between which and a hinged piece 3 the tube 5 to be bent is clamped. A lever 17, pivoted at 16, is placed in a vertical position so that a mandrel 20 on it can be inserted in the upper end of the tube, and the lever is then turned down against a stop 23 to bend the tube to the desired angle. The mandrel is supported by a guide 19 travelling on a rib 18 on the lever which is hollowed out to fit the tube. The movement of the mandrel during the bending is limited by a stop 22. The depth to which the tube is placed in the clamp is determined by an adjustable stop 12 having a pointer moving against a scale on the piece 3. A mandrel is placed in the part of the tube within the clamp.
