interesting sales literature is available

Like the Company's range of small lathes, their No. 644 milling machine did not pretend to be anything other than a miniature utility machine. However, it was honestly made and good value for money: "This bench milling machine is designed to give compactness and solidity in a machine having a remarkably wide range of work at a price within the reach of amateurs, experimenters and every small shop". At 14-inches tall, and with a cast-iron base plate of 4-inches by 8-inches, this was a very small machine, although the weight of 51 lbs showed that little had been skimped in the production of the main castings.
Modelled on the lines of the much more expensive precision millers made by other more illustrious manufacturers (including Stark, the Waltham Machine Works and Pratt & Whitney) the head consisted of a lathe-like unit with a simple 3-speed flat belt drive with cones 1.5", 2.5" and 3.5" in diameter and 1" wide. The spindle, with a No. 1 Morse taper socket and a screwed nose to accept compression collets was ground finished and ran in an adjustable taper bearing. The 11
1/2" x 33/8" table carried a single 3/8-inch T slot and could be operated longitudinally through 7-inches of travel with a screw feed or, with the feed nut disconnected, 41/2-inches by a lever; the traverse feed was limited to just 2 inches. The 7-inches of knee elevation was arranged, like the English Centec miller of later years, though a screw and bevel gear with the operating handwheel at the back of the main casting - an inconvenient location but a design that meant no hole needed to be drilled through the mounting table to accommodate the long vertical screw often used by similar bench millers. On early models a rather unfortunate omission was any means of telling how far the table had been moved in the vertical plane, there being no depth stop, nor any engravings on the vertical feed handwheel. Happily, in later years, this omission was corrected and all versions, no matter when made, were provided with proper graduated dials on both longitudinal and traverse feeds. In 1926 the basic machine sold for $126 with a set of plain indexing centres (shown below) at $55 and a Universal set at $100. At the same time the Goodell-Pratt Model 700 lathe was $44 and its main accessories, the compound slide rest and the milling slide, sold for $85 and $60 respectively.

Very useful Indexing Centres were available in two types: the swivelling (above) with a height-adjustable tailstock at $100 and the plain (below) at $55. The centre height of both types was 11/2 inches and the division ring provided with three circles of 36, 40 and 48 holes; other plates were advertised as being available to "special order".
