Jay's patent "has for its object to provide a portable coffee-roaster, which shall be simple in construction, and capable of being converted into a device for popping corn. It consists in a cylindrical case, composed of sheet-metal, or other suitable material, and provided with a vertical crank-shaft, upon which are arranged, within the case, and at right angles to each other, two horizontal stirrers, one serving to lift the coffee from the bottom of the case, to prevent its burning, while the other thoroughly stirs and agitates the entire mass." (Patent Number 97,644)
