Introduced in the early 1920s, the plain-turning T-L appears to have been a simple pattern-makers' lathe or intended for both wood and light-duty metal work. Lacking both screwcutting and a speed-reducing backgear, this was the only Dalton with a 1.5" x 8 t.p.i. spindle nose and the spindle running direct in the cast iron of the headstock. An oil reservoir was formed below the spindle with a simple "bead chain", sitting in a grove half-way along the bearing, being used to dip into and lift the lubricant. All T-L lathes so far found, no matter how badly abused, have spindle bearings in good condition - a confirmation that, with the right metallurgy and surface finish (as also widely used by tens of thousands of South Bend lathes) this arrangement is almost a guarantee of a long and effective life.
Oddly, for a pattern-makers' lathe (though most usefully), the T-L was fitted with power longitudinal feed by a keyway-equipped drive rod operating the usual type of worm-and-wheel mechanism within the apron (though no parts were interchangeable with Dalton metal lathes). The last patent Hubert Dalton took out was for an effective lift-up-and-lock changewheel guard hinge, and its registration number, together with date (1922), was cast into the bed. Although the same patent number can also be found on later machines of different Lot numbers, the T-L was the only model on which the hinge was used. Using just the changewheels supplied, seven rates of power sliding feed were available from a slowest of 0.007" per revolution of the spindle..
