Retractablebrushes is nothing new. A combined multi-position shaving brush with a built in lather rubber device? That’s more unusual.
Patented by Leon Tobias in 1920, the brush was – of course – touted as a new and improved shaving brush. In the words of the patent:
This invention relates to improvements in shaving brushes, an object of the invention being to provide a shaving brush equipped with the ordinary bristles for forming and distributing lather and also provided with means for rubbing the lather into the face to soften the heard, the parts so constructed and arranged as to permit either the bristles or the rubbing device to be exposed for use at the end of suitable handle.
Whenever I see a patent with a particularly odd name, like “disposable cylindrical razor apparatus”, I wonder if Leonardo da Quirm1 was involved somehow.
So what is a disposable cylindrical razor apparatus? When all is said and done, it is a disposable razor in an odd format. Disposable razors is nothing new, and I’ve covereda few overthe years – some in weird shapes. But what makes this one stick out is that it comes with four cutting surfaces, and looks to be meant to be used as a shavette.
Remember the abandoned patent application I shared with you last week? Remember how I said one reason for the abandonment might be the existence of a lot of prior art? Well, I found one piece of prior art; Dyer T Kendrick’s 1902 patent for a push up shave stick.
