EEDUCTION OF POTATOES. When the potatoes have been boiled suitably, they occupy a greater space, and this dilatation causes their peel, which is not very strong, to be broken ; this ren- ders them proper to be submitted to the action of the reducing machine, of which a description will now be given. This machine is represented by figs. 17 and 18. Fig. 17 is a lateral elevation of it, showing the side of the machine where the two wheels work in each other. Fig. 18 is a plan of the machine, as seen from above, without the hopper. The same letters represent the same pieces in both figures. A A A A is a strong frame built in oak. B and c are two cylinders made of wood or of stone, but better of cast-metal. These two cylinders are of equal diameters; they are a short distance from each other, and their function is to break the potatoes by their unequal rotatory motion. This unequal rotation is ob- tained by means of two wheels of difl*erent diameters, a and 6. D is a movable hopper, supported by the frame in c d. made for the purpose of receiving the potatoes to submit them to the action of the cylinders. E, F are two handles fixed on the axis of the cylinder 0. They serve to work the machine. G H is a scraper. It hangs on e, and the weight g^ which acts upon the lever G e, presses the extremity h of the scraper against the cylinder B. This scraper It is
