Hy′dro-stat′ic Bal′ing-press.

One in which the force of water under pressure is made to compress the fibrous material to be baled.

In the example shown, the beater B is first operated, and, when the process has gone to a certain extent, the beater is made stationary, and the follower D raised. Both operations are effected by hydraulic operation. The suspension rope of the beater winds on the wheel M, which is rotated by pinion and rack, the latter being depressed by a piston in cylinder J. The rope is tripped off the wheel from time to time, automatically, allowing the weight B to fall, and again and again re-winds and slips off. At the proper time the cock is turned and the water turned on to the other cylinder J, beneath the follower D, and the latter is raised by the pressure of water beneath the piston in said cylinder. G represents the material under pressure.

In Fig. 2626 the motive-power is water under pressure. The cylinder A is open at both ends, has two ports, E and F, at the center, to receive and discharge respectively the water from the pump or head. There are two rams B in cylinder A, working in opposite directions toward heads C. G is the space for the material to be pressed. D are connecting-rods, connecting the heads C together to resist the strain of the rams B, and forming guides for the rams.
