Screw-driven vises are not modern inventions. The earliest screw-driven vise that I know of is this Italian vise that is circa 1300. I am always looking for earlier vises because the screw mechanism has been around since Archimedes, though his screw was originally used for irrigation.
This year I have been delving deep into a codex that was written in 1505 by a patrician named Martin Loffelholz. The 76-page proto-book is filled with hand-colored drawings and descriptions of tools, weapons, locks and even a love potion. With the help of some German friends (thanks Görge Jonuschat!), we have transliterated and translated much of the codex.
I’m currently writing a book about the workbenches that Loffelholz illustrated in the codex, but there is a lot of other great stuff in there that I’m going to share here.
Exhibit A is from page 33 of the codex and illustrates a portable vise that can grip stuff when it is above the work surface. Such a vise is great for close-up work (think: saw sharpening) and was a common fixture in shops in the 19th and early 20th centuries. Check out this version from Old Salem’s workshop. The vise also appears in catalogs from the early 20th century, such as this one from La Forge Royale.
The Loffelholz vise is a bit of a puzzle. Did Loffelholz invent it? Or (more likely) is it something that he saw in a workshop and drew in his codex? The translation of the text that goes with the drawing is as such:
Top text: “This screw tightens from this side.”
Middle text: “This screw from the other side.”
Lower text: “A Vise you may screw or pin to anything.”
So we can say that the vise is portable (the pointy pin on the end of the chop is a dead giveaway). And that it screws from both sides. It reminds me of a handscrew especially in that it tightens from both sides.
Also worth noting: the vise has metal jaws. And the garter-looking thing is a mystery to me. I’m at a loss as to why the vise would need a garter there, unless it was the device that engaged the top screw. But that would be weird because the vise would seem to work better if the top screw were fixed in the front jaw.
The only way to answer these questions is to speculate wildly on an internet message board. No. Strike that. The only way to answer these questions is to build the thing.
The boys at Benchcrafted are building a vise similar to this, which they call their Hi Vise. But it’s more like the modern French versions than the 1505 version. So I might have another project ahead of me that will fail (again) to benefit my family. Eating off a bench – or a vise – isn’t easy.
