Grandpa Spaine's patents

Grandpa Spaine

Grandpa Spaine worked for Singer Sewing Machine from his 20s until he finally finished his baseball sewing machine when he was in his 80s. I had always heard that he had several patents, and had even seen the documents for one or two in his papers, but, I didn't know how many or what they were.

Google can be a big help. A quick search of the US patent records turned up 16 19 patents. (the google page only turned up 16, freepatentsonline found 19.)

And, as a bonus, the search also turned up a patent of Uncle Peter's.
