Abstract: A horizontal waste material baling machine has a charging passage which leads to a compressing chamber of generally parallelopiped configuration and in which a charging plunger is reciprocably moveable for pushing waste material into the compressing chamber and compressing it into a bale. A discharge passage leads from the compressing chamber at right angles to the charging passage, and an ejection plunger is advanceable through the chamber and the discharge passage to eject the baled waste material. To ease the ejection of an oversize bale, the discharge passage wall adjacent the exit end of the charging passage is a vertically oriented planar surface of a structure that is moveable by a linear motor, such as a hydraulic cylinder, from a normal operative position at which the vertical planar surface and the opposite sidewall of the discharge passage determine the exit width to a position at which the planar surface is displaced by an amount it is desired to increase the exit width of the discharge passage.

Abstract: A horizontal baling apparatus having a compression ram which is provided so as to be reciprocally movable into the baling chamber of the apparatus, and a mechanism which scales the length of stroke of the compression ram to a total stroke of a potentiometer, from the output of which the density of a portion of a bale of material is determined as well as the necessary amount of additional material which is required on successive laminations to maintain the density.

Abstract: Compactor apparatus comprises a conveyor for supplying articles to a hopper positioned alongside the upper end of a compression chamber in which a platen powered by a hydraulic cylinder is adapted to be reciprocated. The hopper is mounted at one end of a beam balance, the displacement of the other end of which measures the weight of a charge in the hopper. When the presence of a specified charge in the hopper is sensed, the conveyor is disabled, the hopper and hydraulic cylinder with the platen in the retracted position are swung laterally to bring the hopper over the compression chamber to dump the contained articles into the chamber. The hopper and cylinder are then returned to their initial positions, the cylinder is actuated to cause the platen to compress the dumped articles, and the conveyor is again enabled to supply articles to the hopper.
