CHARECO Report post Posted May 19, 2017 Wondering if yall have any resources to find patents for old industrial machines. I am on a quest to find technical drawings for an old industrial singer and have had no luck after days of searching. It appears that a lot if these old machines don't have shop manuals or maintainence guides. I'm thinking the next best step would be an original patent drawing. Any advice or leads would be greatly appreciated Thanks Quote Share this post Link to post Share on other sites
johnv474 Report post Posted June 11, 2017 You can search patents on Google; there is a section devoted to them. That said, there are also a lot of manuals available online if you keep looking. Which specific machine are you trying to find drawings of? Quote Share this post Link to post Share on other sites
