Seldom found, the Kärger horizontal milling machine was made by G. Kärger of Kraut-Strasse 52, Berlin 0.27, a company better known, from the late 1800s, as a maker of high-quality precision plain-turning and screwcutting lathes designed for use in the watch, clock and instrument-making trades.
Containing a motor dated 1942 - but believed to be much earlier - the miller shown below with its flat-belt drive and round overarm, was of a conventional design for the period, but of exceptionally robust construction and with a quality finish. The history behind its arrival in the United States is not known, but it might have been brought over having been used in an American Army repair unit based in Germany after WW2 - a not uncommon occurrence, apparently - or simply imported as a used machine in the late 1940s or early 1950s..
Fitted with a 3-speed power drive by flat belt to the usual carden shaft, the table was a21.625 inches long by 6.25 inches wide with three 17.875 inches long T-slots. Longitudinal drive was also by both a lever and a single, detachable handwheel at its left-hand end. The table drive appears to have incorporated that most useful of features, a drop-out worm by which means to drive could be instantly engaged or disengaged, adjustable stops, carried in a slot on the front face of the table, provided the means for an automatic release. Cross and elevation motions were by screw feed, the travels being 11 inches longitudinally, 6.26 inches in traverse and 8.75 inches vertically (though, oddly, the table could be lifted higher than the spindle nose). One unusual, though useful feature, was a ruler, graduated in mm, and let into the front face of the column to measure vertical travel
Looking very much like the spindle nose of a lathe shown in the Kärger lathe section of the Archive, this had what seems to be a No.3 Morse taper socket, machined on the end with a M39 x 4 thread and a short taper to take collets.
If you have a Kärger milling machine - or any literature about them or other Kärger machine tools, the writer would be pleased to hear from you.
