I offer a collection of 232 historical patents from wellknown company BALDWIN LOCOMOTIVE WORKS, published between 1909 and 1945 in USA (all in english).
They are busy mostly with inventions around locomotive technique (locomotive, frame for locomotive, tender, boiler, piston valve...), but also from some trucks and other technical parts more.
All patents are complete, that means contain the full text and all drawings (see example). You will get a professional overview about the inventtions 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!
