Oak dining table, side board & buffet

I purchased this dining set at auction. It includes the buffet, side board, table with 3 leaves,7 chairs and one chair with arms. The manufacturer's plate is inscribed "Licensed under BROWN patent no. 975,604 - Nov. 15, 1910 : no. 48382".

I'm interested in any information that I can get on the manufacturer, country of origin, etc.

Thanks!
