Unknown Lathes Home Page
Almost certainly by the well-known Ariston Company (who made a vast range of lathes) this interesting lathe was behind in a German army service truck in the Kongsberg area of Norway at the end of World War 2; backgeared and screwcutting, it has survived in remarkable fine mechanical condition. With a centre height of around 125 mm and a capacity between centres of 650 mm, it was stamped on the bed with a Waffen number and swastika - so confirming its likely date of manufacture as being between 1937 and 1944. For its era, this was a reasonable compact machine with a built-on, 2-speed gearbox behind the headstock acting as a countershaft - the drive to the box coming via a wide flat belt from part of the truck's drive system (though what other machinery it contained is not known).High-resolution Pictures--may take time to load
Of remarkably robust proportions for lathe's capacity, the headstock was fitted with plain bearings and 3-step cone pulley for drive by a wide flat belt.
Drive to the screwcutting and feeds gearbox came through changwheels and a tumble-reverse mechanism - the operating lever for this being of typical German (and especially Ehrlich). Although the gearbox was a proper tumbler type, from its appearance (similar to that on other Ariston lathes) the threading range would have been limited - though both a screwcutting leadscrew and power shaft were fitted, the latter driving, though the usual worm-and-wheel arrangement in the apron, to give power sliding and surfacing feeds. A pull-push button on the face of the apron selected the feed direction with a lever on the gearbox to engage and disengage it.
Of ordinary design, the compound slide rest had a cross slide of the short type (that would lead, eventually, to wear in the middle part of the way on which it ran) and a top slide whose stout appearance gives a clue as to the maker - being a typically Ariston design
The bed, with a wide detachable gap piece, was rather unusual in using four sets of V-ways, two for the saddle and two more for the tailstock.
