I offer a collection of over 900 (!!) old patents around chain saw technique from USA and Great Britain, published between 1860 (!) and 1970.
All patents are complete, that means contain the full text and all (often beautiful and informative - see example) drawings.
Most of the patents are busy with chainsaw technique, like chain saw construtions, saw chains, motors and other parts. In the time periode before 1900 the collection contains also some other saws.
The inventors come mostly from USA, but also from some other countries, here are some companies which you can find in the collection:
McCulloch Corp., Stihl (Germany), Chain Saw Co., Mall Tool Co., Omark Industries Inc., Outboard Marine Corp., Remington Arms Co.
The collection is created by the seller and is the world best overview about patent situation of chain saw technique in this long time period!
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 numbers, datas of issue, patent titles and often also inventors and/or owners of the patents.
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!!
Copyright of the CDs has only the seller!
