One of the most satisfactory types belongs to this class. In the center is a circular surface, having at the circum- ference a channel about 6 inches wide and 6 inches deep. In the bottom of this channel two gangs of 8 to 12 knives are placed dia- metrically opposite each other. The material to be sliced is fed upon the middle of the rotating surface, whence a device causes it to be carried outward to the channel, where it is forced over and through the knives by sloping arms. Special machines for cutting beans are made. By means of a vibrating hopper the beans are fed to a revolving drum with pockets that convey the material to the cutting knives. The cut beans are delivered to a screen where the short ends are sorted out. It is possible to buy machines cutting desired Fig. 2.—Hand-operated lye dipper and washing vat In the most satisfactory type of cubing machine the slices are cut, carried to a die, and forced through by means of a plunger. PITTING AND SEEDING Manufacturers find it desirable to pit or seed stone fruits, as pitted or seeded fruits dry more rapidly and sell more readily than those from which the pits or seeds are not removed. Satisfactory machines for pitting fresh cherries are on the market, and efforts are being made to develop good machines for other fresh fruits. The cherry pitter consists of a revolving drum containing numerous pockets, each of which has a hole in the bottom. The cherries are fed into these pockets, which are set in rows at regular intervals. As the drum revolves rows of synchronized plungers force the pits out through the holes in the pockets. Unless it is collected and uti- lized in some way, much
