Abstract
733,642. Angular bending. LAWLER, AYERS & CO., Ltd. June 30, 1953 [July 3, 1952], No. 16718/52. Class 83 (4). A tube or rod bending machine comprises a stationary former having an arcuate forming surface and an arm pivoted so as to move around the forming surface and carrying a presser which is adapted to bear upon the tube to bend it round the former as the arm is swung about its pivot, the tube being held adjacent to one end of the forming surface during such bending operation, the former being provided with a slot so that it may be pushed against the spindle on which the bending arm is pivoted or withdrawn and replaced by another. On to a spigot 12, secured to a bracket 10 a suitable arcuate-surfaced bending former 13, slotted at 14, is slid to abut an upright face of the bracket 10. The former 13 may be secured to the bracket 10 by a screw. A bifurcated lever 17, carrying a pressing roller 18 adjustable axially of the lever by a screw 20, is pivoted on the spigot 12 and embraces the former 13. In operation a tube 30 is inserted, with a guide-bar 31, between the former and the roller 18 and the bar 22 longitudinally adjusted so that a pivoted grooved block 23 thereon presses against the tube. The lever 17 is then rotated to effect the bending. The block 23 is formed with two grooves 24, 25 of different sizes to co-operate with different tubes.
