Actually, Now that I dug this out, it appears the company was 'Brown Machine Co.'
I know they made line throwing cannons, from early muzzle loading to something that took a 2" cartridge. I have one of the patterns for a small (1" bore) cannon. They also had another company called the Brown Beer Pump Company, who made the first electric motor driven beer pumps.
Wm. Asaph Brown was my mother's Grandfather. His son, my Grandfather was also William Asaph Brown. He was an Episcopalian, and was married to Mary Stack, an Irish Catholic. My mother was the 2nd of three children, and raised Episcopalian. Her older sister was a Roman Catholic Nun, and her younger brother was also raised Catholic. The night my grandfather died, my Grandmother, and Aunt brought a priest in and had my Grandfather converted to Catholic. My mother never spoke to anyone in her family again. Consequently, I know very little, and have never bothered to look up anything else.
