Parkinson "Parkson" Lathe
Far better known for their range of milling machines, Parkinson also manufactured, from approximately 1890 to 1918, a range of conventional centre (engine) lathes. The model shown below, with its distinctive 5-spoke apron handwheel and marked "War Finish" would have been constructed during WW1 (1914-1918).
With a centre height of 6.5 inches and 6-foot long bed, this was a robust machine intended for use in a general engineering or repair shop. The makers described it as their Anglo-American lathe'.... designed to combine the best features of the English and American types'. - and indeed it did bear a resemblance to contemporary Lodge and Shipley models (and the dainty tumbler reverse trigger was almost a carbon copy of that fitted to the American Pond). However, the bed was a traditional English type with flat-topped ways, massive 60-degree edge shears and channel-type cross bracing webs. The apron, with power feeds driven by flat belt through a separate shaft that carried a 4-step pulley, reflected American practice of the time with neat, rotary-handle-operated clutches for surfacing and sliding and the carriage-traverse handwheel positioned on the left. One unusual - and most useful - feature was the huge mandrel bore, a clear 2" clear all the way through, though this caused there to be insufficient room to machine the nose with a Morse taper insert (this was a standard feature, not a previous owner's modification, and mentioned in the sales literature). As on most-pre-WW1 machine tools (and the introduction of cut-down, material-saving sizes) everything was held together with the early type of Whitworth bolts with their distinctive over-large head.
