Typical rear view of a 15" to 20" toolroom lathe

Individual drive from a headstock-mounted motor by a sort flat belt to the headstock input pulley
At first, drives were often arranged individually to suit a customer's particular preference, a choice being offered of flat belt from a factory's existing line-shafting or by a motor carried on top of the headstock or inside the headstock end bed-support plinth. With the motor attached to the lathe a variety of other systems could be ordered including by flat belt,  "silent chain" or through fibre gears - the 1920s being, after a decade or more of experimentation, a time of flux as makers struggled to come to terms with an increasing demand for machines tools that featured an integrated drive system. By the early 1930s the matter was solved by the introduction of reliable V-belts when, from small to large, lathes could be equipped with single or multiple pulleys to transmit the required 0.25 to 10 h.p. from motor to headstock

Drive from motor to headstock though straight-cut gears. To help silence the drive one of the gears was often in fibre

Plain-bearing headstock

Timken taper roller bearing spindle

Headstock with main spindle removed

Apron with its separate, quick-action, over-centre engagement levers for the power sliding and surfacing feeds. Note the rather delicate proportions of the carriage handwheel

Rear of the apron showing the power-feed reversing mechanism. Oddly, in this art-worked illustration, the maker omitted to show the left-hand section of the leadscrew and its bevel gear.

Saddle with its equal-length, T-slotted wings

Taper-turning attachment

Compound slide-rest assembly

Set-over tailstock with twin clamping bolts. The ball that can be seen in front of the spindle lock handle had a shaft that dipped into (poisonous) white lead to lubricate the centre

Draw-in collet set

Countershaft listed for lathes with 14", 16", 18" and 20" swings. The two single right-hand pulleys ran in different directions and were locked to the shaft by toggle-operated clutches
