When you say post card, you usually think of something vivid and touristy that you’ll mail of to distant relatives when you’re on vacation. But a post card is – when you come down to it – just a piece of thick paper or thin cardboard that you write upon and send in the mail with no envelope. No one ever said it had to include the words “wish you were here” on the back.
Continue readingThe result of over four years of careful study and experimentation. Made after secret formula, and with a superlatively keen edge. So hard it will cut glass. Keener and more durable. And no, I’m not referring to the ad copy of the latest multi-blade plastic horror to be peddled by Gillette. I’m referring to the ad copy from a 1908 advertisement for their “new process” blade.

Like so many others – Edward L Corbet, John T Cooney, Marguerite Faučon, and Aron Braunstein & Angel Rattiner to mention just a few – inventors, Gustav Koch searched for a sanitary, hygienic, and disposable shaving brush. If it worked well for making lather, it was a bonus. If it dodn’t need a cup, that would be one less unsanitary item to worry about.
Continue readingSimplicity is often seen as a goal. And sometimes it can be taken too far, as with Samuel C Yeaton Jr’s simple sheet metal razor patented in 1910. Which is not to say that he described it in simple terms.
To quote from the patent text:
My invention relates particularly to safety razors and comprises a holder for retaining the razor blade adapted for use with a blade having two cutting edges, oppositely disposed, and is constructed to permit the repeated use of the blade as often as it is resharpened. The retaining frame comprises two sides, upon whose outer edges are formed protective combs having the ends folded over forming lips. The four corners of the blade are held in spring pressed engagement between these lips. This always insures accurate and correct positions of the cutting edges upon their respective combs, which is not altered (owing to the spring pressed engagement of the lips) when the razor is reduced in transverse dimension after it has been resharpened.
In short, it’s a springy sheet metal piece that has been bent into the shape of a razor. The blade stops presses against the blade, and holds it in place. There is no top cap, as we know it from a regular three piece razor.
It is worth noting that the razor was clearly meant for blades that was meant to be sharpened and stropped. The ‘normal’ double edged blade – as known in 1910 – would likely not be suitable for use in Samuel’s razor. A modern, thin double edged blade would be too flexible to be usable. But with a blade more suitable for the razor, there is no reason why Samuel’s simple sheet metal razor wouldn’t work as intended.
Of course, Samuel’s razor isn’t the first simple sheet metal design we’ve had a look at. Among others, we’ve looked at Camfield’s simple injector, Parkinson’s folded razor, Greist and Boyler’s inexpensive razor, and Jackson’s one piece razor. And a fair bit more, as you’ll find on my blog.
What makes Samuel’s simple sheet metal razor stand out is that pressure is applied to the edges, as opposed to the flat sides of the blade.
The patent is, naturally, long expired. It won’t work with a modern, flexible double edged blade, but the design should easily be modified to take a stiffer single edged blade like a GEM. The question is why?

On Tuesday we looked at a somewhat portable barber’s chair and stool, from 1865. But the need for a portable barber chair seems to still be with us, because in 2020 Sandra Riley applied for a patent for her Cut and Go Barber Chair.
She is also helpful enough to give a detailed background for why she came up with the invention:

Fear not; Henry Remick have patented a handy, folding chair and stool for barbers (and also dentists and so on). It also came with a telescoping barber pole, because… because why not, I guess.
Continue readingAt the turn of the last century, Amos H Jackson patented a one piece razor made from sheet metal. Well, he patented two, but the first one was not quite a one piece razor.
Continue readingWilliam Herzberg patented an indicating sealed shaving cup in 1911, as part of the quest to make sure that your barber didn’t infect you with whatever ailment the previous customer had.
He was not the first, not the last. We have looked at a great many solutions to that problem over the years. But his solution was different enough and simple enough that it warranted a look.

But what about the soap that sat in the grip? There is at least half an inch of soap in there.
No need to waste it though:
