Timothy wroteI’m sure we all know what the Push key Padlock look like. I found this Patent US1196218 as this is what they call Keyless Lock. I have never see this lock anywhere and it would be nice to know what it really look like…….Timothy…..
Interesting find, I wonder if it was ever manufactured? Pre-dates the 1939 US Patent 2183168 for the Sesamee “permutation” padlock originally made by Bemis & Call of Springfield, MA by over twenty years!
