Abstract

251,181. Harvie, D., and Harvie, D. Oct. 31, 1925. Pipes.-In making expansion balls for pipes a die-holder 1 carried on stools 2 is inserted into the pipe 3 and supports interchangeable dies 4 with synclastic surfaces. A movable die 5 with counterpart surface is actuated by a ram 6. The shape of the die 5 is varied by pads 7. The pipe is rotated step by step between the pressings and is annealed at the completion of each cycle of operations. Specifications 1097/77, 2671/88, 4680/88, and 107,492 are referred to.
