If any reader has a C.L.H., the writer would be interested to hear from you
One of only a few indigenous designs of watchmakers' lathe from the United Kingdom, the C.L.H. was manufactured by C. Levitt & Son of Stockton-on-Forest, near York. Several versions are known to have been offered, including the conventionally arranged Geneva-pattern No. 14 with its main castings in bronze, a 40 mm centre height and a spindle to take 8 mm collets - and the almost identical No. 11 with a bed so short that it was unable to mount a tailstock.
Designed to be clamped in a vice, the very rare bronze-body No. 7 is shown immediately below. Of simple, one-piece construction and 5.5-inches long, it was fitted with a ground spindle running directly in the material of the headstock - the casting being split on one side and fitted with clamp screws, a most unusual arrangement for this class of lathe yet one which, in practice, worked perfectly well. The 0.5-inch diameter spindle took 8 mm collets and was turned by a 2-step pulley overhung on its outboard end, a simple and cheap-to-produce solution. The tailstock was of the most basic kind with just a push-spindle 0.25-inches in diameter and a locking screw that bore directly against it. Following the company tradition of offering lathes without tailstocks, a No. 8 version was also produced; this was identical to the No. 7 but with a bed cut short and just long enough to mount the hand T-rest assembly.
Shown at the bottom of the page is what could be another version of the C.L.H. - though this is a much more complex machine that lacks any maker's marks and may well be by another Company altogether.
Over page are two other types: one that might well be an early version with the simple split headstock bearings supported on slender posts, the other with a most odd "triangular" form of bed turned round at the ends.
