Description: I offer a collection of over 600 (!!) patents around pencil sharpeners / pointers or relating items from USA and Great Britain between 1920 (!) and 1980 (all in english). All patents are complete, that means contain the full text and all drawings (see example - often the drawings are artful and informative). The patents inform about pencil sharpeners / pointers or also chalk sharpeners of various types or parts of it (for example blades). Partially the patents are busy with such objects in connection with others like pen rack, envelope opener, pencil case and some more. The owners / inventors comes especially from USA and GB, but also from some other countries like Germany and Japan. You will find for example documents from Automatic Pencil Sharpener Company (APSCO) and Boston, but also Möbius, Jupiter and Avanti (all from Germany). I think that it is a very interesting material for all collectors of such objects.Also included is an Excel list with patent numbers, datas of issue, inventor and/or owner names 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. This is a very comfortable way to exploit the extensive document material. 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 or use any other free open office 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!! Delivery is as pdf-file collection (*.pdf) on CD (not as printed book!). Each file contains one complete patent. You need only the wellknown free programme Acrobat Reader or a similar one to open the files. You can also print each file. If you take for example "antique style paper" you can make nice pictures for wall decoration for yourself. Copyright of the CD has only the seller! Shipping worldwide as airmail letter. You can also buy more patent collections - the shipping price will not increase!
