Hi All,
IMO, the best way to get free ((in .html format for automatic translation and .pdf format for the drawings) or only .pdf format) patents is to use the Swiss Patent Site at this URL:
http://l2.espacenet.com/espacenet/viewer?PN=********&CY=ep&LG=en&DB=EPD
where ******* is the number of the patent.
Example:

If you want some gravity wheels patents, please just check out:

Three old French patents about gravity wheels.
You don't speak French? Ask me for more informations or just study the drawings. Very informative.
An old stange Irish one:
