A lot of patents I’ve discussed are about making your shavegear smaller, handier, and more portable. And it makes sense, in a way, to have things that pack small for travel – doubly so in the days before we all drove automobiles. So I can see why Charles Finley applied for a combination drinking cup and shaving mug back in 1901. I just don’t see why anyone would combine the two.

Sadly the patent don’t say why Charles felt this was a good idea. But it does claim it to be an improved combined cup and mug, so there must have been some earlier (and worse) versions of this.
