In the machine represented in Fig. 2 the upperrollers arc c(n-rugated, and are 17 in. in diameter and 136 in. in length. Heavy car-springs arearranged between the boxes of the adjustable roller. The lower rollers are smooth, 24 in. indiameter and :36 in. long, and are geared to run at differential motion. The height of thismachine is .5 ft. (> in., and it crushes clay sufficient for from to bricks per day. The Ports Claj/ Disinfegrator, illustrated in Fig. 4, is especially adapted for tough, stonyclay, which it pulverizes by removing successive
