Chapmans patent (4411 of1875) claimed the 2-roller mill in con-nection with Russels maceration scheme(4094 of 1874), and a very similar patentwas taken out by Rousselot (5050 of 1876). In a later patent (2280 of 1878),Rousselot added a small feed roller to the 2-roller, as shown in Fig. 136. Atthe same time the 2-roller miU was developed by Alexander Young in theHawaiian Islands. Difficulty in feeding whilst maintaining the pressureprevented the adoption of this type. To overcome this trouble the forcedfeed of Riley (patent 17776 of 1891) was tried, Fig. 137. In this device areciprocating pusher bar, a, is driven from an eccentric or crank througha rocking shaft b, and forces the bagasse into the miU. Very similar arrangements were patented later by Fletcher (16118 of1892) and Kidd (15301 o
