Linkage research

[unk]

I have thought up a linkage than does straight-line motion.

It's not (as far as I can tell) like any of the examples on the net.

Are there others/other places to look as this one must have been thunk up
before.

That can cover a lot of territory. Besides the classical linkages
described in Jim's link, and a limited Watt's linkage, there is the
rhombic drive, used in advanced Stirling engines, and the linkage used
in the original Atkinson-cycle engine patents.

But the definition of a straight-line linkage can get a little fuzzy,
depending on who'se doing the defining. It basic terms, a conventional
crank, driving a piston in a constraining cylinder through a
connecting rod, produces "straight-line motion."

There also are a couple of books, the titles of which I can't
remember, that describe all kinds of new and old mechanisms. I recall
that quite a few of them were mechanisms used by designers of
production machinery, which tends to have a lot of rotary-to-linear
motion requirements.

Have you looked at the old books via archive.com? Like:

Undoubtedly you'll find it or a close variant in one of Leonardo's
sketchbooks... :)

Have a browse through this book and see if its in there:

Mechanisms and Mechanical Devices Sourcebook.

[DoN. Nichols]

Try _Ingenious Mechanisms for designers and inventors_, a
four-volume set edited by Franklin D. Jones, published by Industrial
Press, Inc. While the volumes which I have are perhaps ten years old or
so, but has a copyright date of 1930 for Volume I.

Enjoy,
DoN.

404 error, sadly. Here's a google link to it:

I was about to suggest both of those, Leon.

They're great to relax with, spending a rain/snow day inside.

Oops, that one resolved to elephant-ads. Do not go there.
