Manufactured by Globe Products Mfg. Co. of 3380 Robertson Blvd., Ashley, Los Angeles, California the Globe lathe milling attachment had a principle of operation like that of a "Lincoln" miller where the workpiece, instead of moving, was clamped to a table and the cutter head made to travel across it.
Very heavily-built, the unit was available with a base machined ready to fit a variety of popular lathes - including Atlas and Craftsman  9", 10" and 12"; Clausing and Logan 10", Sheldon 10", 11" and 12"; South Bend 16", Workshop 9", Model R and Heavy Ten and the Lodge & Shipley 18". Other fittings could be supplied to order and the Company boasted of  Government contracts to provide specially equipped and develop units for a variety of novel purposes. Although not mentioned in the advertising literature, the unit may have been made in more than one size and models marked 90-91 50-51 have been discovered. The spindle was, likewise, available with a variety of fittings, commonly being specified with  a 1-1/2 inch x 8 t.p.i. nose thread and either a No. 2 Morse or No. 9 Browne and Sharpe taper.
Built in two main parts, the attachment consisted of a spindle-carrying head mounted on a vertical slide and a cross slide to replace that normally fitted to the lathe. The head was clamped to the lathe bed and driven by an adaptor that plugged into the headstock; the 12" x 41/2" slide with 4.5 inches of travel (on the 50-51) carried a single 3/8" longitudinal T slot that allowed various work-holding fixtures to be mounted including an ingenious "hinged-tongue" vice, a raiser block and a simple but effective 4.25-inch centre height dividing head with matching tailstock. A third component was also available: an arbor support casting that was braced by having a recess for the tailstock ram to enter and the base held between the bedways with an expander screw used to secure it in place. The support casting carried a slideway with an adjustable ball-bearing support into which the end of the 8-inch long arbor could be fitted.
Like all designers attempting to provide a universal milling head for lathe mounting, those of the Globe faced two main problems: how to provide a neat, self-contained multi-speed drive (which avoided heavy, complex and costly overhead belt runs) and how to keep that drive working as the head was raised and lowered. The Californian engineers solved the problems by arranging for the headstock spindle to provide the power and speeds (via a plug-in adaptor) and for the A-section V-belt drive to go first to a two-step pulley and from there to the spindle by a second belt (at a ratio of 1 : 1) with the tension adjusted (as the head moved) by a jockey pulley bearing against its back surface.
Constructed in close-grained cast iron, the main castings were fully normalized to relieve stresses before machining, with the slides finished by hand scraping. The spindle was made in a "high-grade steel" and rotated in double shielded ball bearings lubricated through simple flip-lid oilers. The Acme-form elevation screw was a generous 0.5-inches in diameter, ran through a bronze nut and was fitted  with the zeroing micrometer dial graduated in intervals of 0.001"; the thrust was absorbed against a hardened steel collar.
One ingenious use of the unit was to mount a lathe chuck or other fitting on the end of the spindle and use the unit as a sub-headstock of increased centre height (in the pictures below an owner has constructed a most useful 19-inch diameter faceplate to take advantage of this) A raiser block was also provided to mount on top of the Globe cross slide and carry the lathe's ordinary top slide.
