Old Coffee Roasters                                                                

This Patent was quickly replaced by US Patent 772,498, http://www.oldcoffeeroasters.com/'04_screen.htm which was Manning Bowman's new screen design that was used in all of their future spray percolators. I was lucky in acquiring this early example before they switched to the improved screen design.
