Of very unusual design and unknown date (though it may well have been current in the 1920s) the 4-inch centre height by 10-inches between centres plain-turning E. A. Adams lathe was made in Providence, Rhode Island. The bed was formed from a box-section iron casting with, in a reversal of usual practice, the flat-topped V-edged carriage way cantilevered out to the left - an arrangement that offered the headstock very little support. The slender tailstock, with its spindle clamp a crude, direct-acting screw, was better provided for and, when extended to allow the lathe's maximum capacity to be used, was only a little to the right of the main mass of the bed. The headstock, whose bronze bearings were threaded on their ends and, for adjustment, drawn down into their tapered seats by large ring nuts, continued the theme of "flexibility in construction" with the left-hand bearing held on the end of a slender arm and the right on top of a short, unbraced vertical post.
Although the makers was good enough to specify a compound slide rest this was, unaccountably,  carried on top of a vertical slide running in ways formed on the front face of the apron. Although this arrangement meant that the tool height could be quickly and accurately adjusted (by a very small-diameter handwheel) it brought in its train even less rigidity between the cutting tool and workpiece.
The slides' feed-screws were bereft of micrometer dials and the cross slide had a very limited travel whilst the carrier for the feed screw was a simple flat plate - and not the type of extended  housing that would have allowed the slide extra travel by being allowed to pass over its ways.
If any reader has an E. A. Adams lathe the writer would be interested to hear from them.
