BENDING PIPES

[graphic][subsumed]

T HE pipes or tubing shown in the

accompanying photograph were all

bent on a recently invented machine. They range from one to six inches in diameter, the radii of the bends being from three inches to three feet. The time for making these bends varied from one half to two and one-half minutes. Some of these bends, done by hand, would have required a gang of men, gas or fuel of some kind, and several hours of labor, so that in the saving of expense this machine pays for itself in a short time.

A 51-horse-power electric motor drives the machine, and it operates on any shape of pipe or tubings and makes any shape or style of bend.
