Rocking in Tawas

Hi folks! This is a folding rocking chair I purchased at a local thrift store here in my hometown of Tawas, MI. The metal tag on its side reads:
"GOLD MEDAL" Folding Furniture Co.
Racine, WIS. Made in the u.s.a.
Patents Pending
I am having a problem with the research dating and naming the chair though.. If anyone has any information as to when it was made and the style name i would appreciate it very much!
So onto my story. In the store a gentleman was carrying the chair in its folded state and I payed little attention until he opened it up and placed it on the showroom floor. To my surprise he was a volunteer for the store and wasn't someone buying it. Swiftly I walked over to it, collapsed it and asked the selling price. The man shrugged and said five bucks! Elated, I opened my billfold and soon after it was riding next to me on the way home!
I found this to be probably one of my favorite pieces of furniture that I own. It is old. I do know that much but very funtional and comfortable infact I am sitting in it as i type. And for those reasons I am very proud to own it. A fisherman, guy I didn't know, offered me one hundred dollars one day as I sit rocking on the dock watching my poles. I laughed and kindly said thanks for the offer but its not for sale. He didn't have any information about the chair nor did I fish for any from him. But that made me even more proud of it and still every day I take it somewhere I get several comments of admiration about this darned ol' good chair.
Thanks for your time and any information you might have leading to the identification of my chair. Jeff
