There is more to the shave than just a razor. You will need a brush, a shaving soap or cream, a mirror, and somewhere to store it all. And it was the last bit that Marcus B Behrman filed a patent for in 1922, on behalf of the American Safety Razor Corp.
The ORC of the patent is – quite honest – far from good, but the scanned images are good.
In short, it’s a small cabinet with two shelves. One with slots to hold the brush, razor and cream, one plain for holding blades and other bits and bobs. A pocket in the door holds the mirror, and a few holes in the bottom helps circulate the air. And that is – as they say – that.
The full patent can be read at Google Patents – I suggest downloading the PDF and read that instead of the OCRed text.
