Thread: Need help with chuck trademark

Hi GQ,

There is a good listing of German Machine tool trademarks on Wolfgang Jordan's website.

This is Wolfgangs trademarks page..
Deutsche Werkzeughersteller & -händler: Wort-/Bildmarken

This list is taken from the book 'The German machine tool industry' [ DWI ] (1942).

I have a copy of registered trademarks on base metal goods but it's mostly pre 1900, and I suspect that mark is post 1900.. anyway, your mark isn't listed there.

Wolfgang is a member here, but I don't think he often frequents the darker industrial recesses of the hard core metal forums....

Regards
Ray

PS Here's a short list of possible matching German Marks
AB put together in a hexagonal field = Hastener Werkzeugfabrik August Berger, Remscheid
GNP in the hexagon = Brockhaus sons, Oesterau b. Plettenberg, Westphalia
BZB in hexagon = Bernhard Zade, Berlin-Kaulsdorf
EH in the hexagonal Sterm = Ernst Hoyer, Hamburg

It looks like JK, or maybe KJ.

Are the marks at the bottom of the logo three letters? To me it looks like CS A or C5 A. the last one (A?) is very indistinct.
In any case they don't seem to tie up with any of the companies in Wolfgang's trademark page list.

This may sound silly but if it works, reasonably accurate for the purpose why fret over what brand it may be? Sometimes the little bits hold up things for years.

Does anyone speak Japanese. It looks like Japanese writing as they both join up perfectly.

I have tried, between orher duties, to post a picture in the proper, oriented 90 degrees right, orientation. In that position there is a "J" superimposed over a "K" in the centre of the hexagon.

Mike lives in the world of curators and documented historical truth. As a practical matter his lathe is a typical circa 1913 instrument maker's lathe, but it would be nice to have some more data points. There is evidence, for example, that it lived originally at Sopwith's. Maybe it made Camel parts?

Since Michael is far too polite to ask I took it upon myself to indulge his life-long habit of investigation of our common history.

If it is German, and made during the Nazi regime time, it would be likely to have the Eagle and swastika stamp on it . They loved stamping anything and everything with that stamp.

I have a couple of their Morse keys, made from a reddy tan coloured bakelite , the tiny Nazi stamp is there on them ! And, on the valve covers of their radios , the same tiny stamp , in ink. MIKE

Hi Greg,

More information the better, even seemingly irrelevant detail can sometimes provide the vital clue that can unravel the identity.

The only remote possibility I can come up with for a German mark might be Kolb, they listed their mark as a K in a hexagon, but no "J"

Since it's origins might be British, Grace's Guide is one the best sources for British machine historical records.

There was a JJ Kershaw in Manchester that made lathes in the late 1890's, but I haven't been able to find their mark.
