Remember that book I committed a while ago? I’m in the process of putting a sequel together. Expect it sometime early in 2022.
The biggest trouble will be to come up with a title…
I’m committing a second book

Adapter for a handle and a cartridge of different razor systems
Don’t you just hate how your preferred handle don’t fit your favourite razor blade?
No, me neither. After all, all double edge blades based on the Probak / Gillette patents fits virtually all double edge razors.1 In the same way, virtually all injector blades will work with virtually all injector razors. And all GEM blades work with all GEM and EverReady razors.
If, however, you’re not engaging in what I consider “traditional wetshaving”2 but are using cartridges instead… yeah, then you may be familiar with the problem this patent is trying to fix.

The stationary – as in bolted down – shaving cup was not Angelo Piccione’s1 first foray into making an overly complex self cleaning lathering cup. Six years before the stationary cup he filed a patent for a, well, lathering device. The objective is more or less the same as his later lather cup. In the words of the patent text:
Continue readingThis invention relates to lathering devices for use by barbers to produce lather for shaving purposes, and has for its object the provision of a device of this character which permits of easily and conveniently cleaning the cup and brush after each shaving operation and thus render the same more sanitary as well as facilitating the work of the barber.

Stationary shaving cup
Angelo Piccione filed a patent for a stationary shaving cup in 1928. Which brought up some odd mental imagery, since in my line of work the opposite to stationary is self-propelled or towed…
A number of inventions straddle the line between insanity and brilliance. And while it’s clear that Piccione took a large step towards one of the two sides, I’m not sure what way he went with this.
Not only does Piccione’s invention sounds like it was a piece of heavy machinery, but the patent drawing1 also looks the part too. We got multiple valves, springs, and linkages. We got pipes, sprayers, and tie-rods. I can easily imagine this device in shiny brass, chrome, and glass – and part of me really wants one.

A shaving cup for a neat freak
Even a neat freak like to shave. And to make things tidy afterwards. Which is why the square shaving cup invented by Vincent Arra might be just the thing. Patent was filed in 1952, and granted in 1956, and have more numbers and arrows than most patents for shaving cups.
A lot more numbers and arrows. Let’s pick those apart, shall we?
Continue readingA more modern shaving cup
Most of the shaving cup and shaving mug patents I’ve have riffed on are old. Some are very old. But today I have a patent for a modern shaving cup to share – patented only twenty nine years ago!
Continue readingAnother revolving razor
A few days ago I wrote about a disposable revolving razor from 1966. Unshockingly – since there is nothing new under the sun – I found a broadly similar idea patented a few years prior. Funnily enough, the patent filed by Mr Alfred Curci1 is – in my eyes at least – an improvement upon the idea patented later.
I guess the chicken came before the egg, in the case of disposable revolving razors.
Continue readingEight shoot “revolver razor”
There are good ideas. There are bad ideas. And there are weird ideas. And this patent – which I can only think of as a revolver razor – is definitely a weird idea. Although I’m sure the intentions were good. Imaginably titled “disposable multi-bladed safety razor”, the patent was filed by Mr William M Choate in September 1966, and granted two and a half years later.
The basic idea is sound; Why should a disposable razor be good for only one – or at best, a few – shave?
Continue readingDisposable razor suitable for injector blades
Not all razors are meant to become heirlooms. Some are meant simply to be a disposable razor. Or, as Roy E Mullen said it in his 1966 patent application:
Continue readingThere are many occasions when an individual would find the use of a good razor to be a comfort and convenience, under circumstances where the services of a barber are not readily available and where it is either undesirable or uneconomical to purchase an ordinary razor.
