    Fig. 206. If a water-power is not at command, the machinery may be driven by a single horse attached to a shaft at the outside of the building. Motion is conveyed by a lying shaft, to the wheel A, and this, by the pinion B, gives motion to a shaft, on which is a crank I), as seen in Fig. 206. By this crank, and the connect¬ ing-rod K, motion is conveyed to the beam E, which is thus al¬ ternately raised and depressed. To this beam is attached the handle F connected with the cross-handle GfH. This handle passes through a hole in the lid of the churn I, and to the lower part of it is fixed a circular perforated board, fitting the churn. Motion being given to the machine, the handle is raised and de¬ pressed, and, by a rapid succession of strokes, the milk is speedily churned. In order to render the strokes longer or shorter, as may be wished, the end of the connecting-rod K can, by means of the screw L, be moved nearer to, or farther from, the centre of motion of the beam. When it is nearer to the centre, the end of the beam makes a larger sweep, and longer strokes are given by the handle. The size of the churn may be sufficient to contain 7 0 gallons of milk or more : or, there may be two churns, with handles attached to the same beam. This machine has been found to be greatly superior in efficiency and despatch to any that had been before in use. Butter may be obtained either by separating the cream from
