American Safety Razor Corporation

I came across this bit of research about the American Safety Razor Corporation by Ulysses Pantoja (@udrako) from Brazil.

He agreed to translate the text into English and allowed me to host this and a German translation on my web site.

There are five parts and they are available in English, German and the original Portuguese.

Any patent numbers mentioned and any patent images are of course clickable links.

Timeline

Member @mata_66 on the Badger & Blade forum has made a chart detailing the history of the American Safety Razor Company.
The original document can be found here.
I'm trying to convert his work into a timeline web page with images for all the razors mentioned.
