Description: I offer a collection of over 1400 (!!!) old patents around piano-fortes from USA between 1838 (!) and 1899. All patents are complete, that means contain the full text and all drawings (see example). The amount of the material is about 5000 pages!! The patents are busy mostly with piano-forte, parts/attachments of it (grand piano, upright piano, piano-action, tuning-attachment, damper, sounding boards, lock for pianos ..) and also accessories like piano stools. The inventors / owners are single persons and a lot of companies, for example also Steinway. They come in most cases from USA, but also from some other contries. You will get a phantastic overview about the technical details around piano-fortes! Delivery is as patent collection of pdf files (*.pdf) on a CD (not as a book). In order to see and to print the files you need only the wellknown Acrobat Reader or a similar programme. Also included is an Excel list with patent numbers, datas of issue and patent titles. The list is linked directly to the patent files so that each patent will be open easily if you click on the link.It is not really a problem if you do not have the programme Excel from Microsoft. Look for "Excel Viewer" at google and you will find freeware version of an Excel Viewer programme. So you can open and print the Excel table without problem! Of course you can open each patent file also direct without using of the Excel table!!Copyright of the CD has only the seller!Shipping worldwide as airmail letter.
