Notable as the world's first lathe with an integrated all-V-belt drive system, the Atlas manufactured but Craftsman-badged  9-inch "compound-drive" has also been discovered as the "Metalcraft ", "Partner" and "Metalmaster". A U.S. patent, number 1909522, was granted on May 16th 1933 to one Mr. James G. Collins - but assigned to the Atlas Press Company of whom, presumably, he was an employee. Sold through the Sears mail-order company both lathes had straight-sided box-type bed feet identical to those shown in the patent drawings - and quite different to the splayed feet on the models illustrated in the first Atlas catalogue.
If any reader has details of how these machines were marketed - especially the "Metalcraft" for which separate catalogs and advertisements must have been prepared -  the writer would be very interested to hear from you.

A remarkably fine and original early Atlas 9-inch Atlas--only the ball on the belt-tensioning lever appears to have been modified

A tailstock-end view showing the very light leadscrew bearing-support bracket. So fragile was this component that it often snapped off - in a usefully sacrificial way - when the carriage was accidentally run into the chuck or tailstock

On its introduction in 1932 the lathe caused a sensation - instead of flat-belt drive from a clumsy wall-or ceiling mounted countershaft and motor, here was the world's first with a neat, built-on countershaft unit and all-V-belt drive. A basic arrangement much copied since and still in use today

Semi-circular finger grip groove to engage the high/low pulley drive setting

Simple but effect screw-down grease caps lubricated the countershaft bearings

Be responsible for your own safety: changewheel guarding was perfunctory - and non-existent over the belts

Pressure die-cast ZAMAK changewheels in place arranged in a compound reduction for a slow carriage feed

Lightweight but commodious changewheel bracket allowed a vast range of pitches to be generated
