I offer a large collection of more than 950 (!!) old patents from USA around telegraph technique (telegraphs, electrical, electro-chemical, optical type, printing telegraphs, telegraph wires, insulators of wires, construction of cables ...)  between 1840 (!) and 1880.

All patents  are complete, that means contain the full text on thousands of pages and all (often beautiful and very informative - see example) drawings.

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.

Also included is an Excel list with patent titles and datas of issue.

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. 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!!
