work required is that of placing the tracing and the blue print paper on the continuous traveling belt. There is no need of working in a darkened room, as the lightproof compartments take its place.

been invented for use in large potato fields where scientific harvescing methods are required. It is drawn by horses and operated by a light-weight, 4 horse-power gasolene engine. This machine lifts out the roots and loose potatoes, separates the clinging potatoes from the dried vines, and deposits the potatoes in crates.

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.
