I offer a collection of
73
patents
of
Kimball Company or W. W. Kimball
, published
between 1866 and 1940 in the USA
(all in english).
They are in most cases busy with
various piano and organ technique inventions (including some inventions to automatical piano / musical devices)
of this wellknown company.
All patents are complete, that means contain the full text and all drawings (see example). You will get a professional overview about the inventions of this company, which you find nowhere in the world in this good quality / completeness.
Delivery is as a zipped file with a patent collection of pdf files (
not printed, not a book
).
You need only the wellknown free programme Acrobat Reader or a similar one to open the files. You can also print each file.
Copyright of the patent collection has only the seller!
