Abstract: A vertical baler includes a housing defining a compacting chamber which receives a vertically moveable and power operated horizontal platen. The chamber has a front opening, and the lower portion of the chamber is closed by a pivotal door member which is secured to the cabinet by a latch mechanism including two separate pivotal members releasably connected by an over-center lock element. The upper part of the opening is closed by a vertical safety gate member which retracts upwardly and is partially counterbalanced by a torsion coil spring having one end portion secured to the housing. The other end portion of the coil spring is connected to a shaft supporting a pair of winch members around which are wrapped corresponding cables connected to the lower portion of the gate member.

Abstract: A vertical baler has a generally rectangular compacting chamber defined by vertical wall members extending from a base, and the chamber is closed by pivotal front doors and a vertically retractable safety gate. A vertically movable horizontal platen is suspended within the chamber by a hydraulic cylinder, and batches of scrap material compacted within the chamber are held down by dog members some of which are pivotally supported. A set of flexible bale ejecting members are coupled to the pivotal dog members and bias the dog members inwardly into the chamber when compacting material, and the ejecting members are then coupled to the platen to provide for ejecting a tied bale in response to upward retraction of the platen.
