I found a strange tool at a garage sale. Nobody knew anything about it. On both sides it says
The National
PAT Nov. 11 1922.
It has a clamp to attach it to a workbench, and a weird gear sliding thing. Nothing has come up on google. Any ideas?
Thanks.
I believe patents were issued Nov 7,1922 and Nov 14, 1922 but none issued Nov11,1922. Possible wrong patent date on casting.
looks like a press to push something into a square can?...
