  • Patent number: 10245799
    Abstract: Baler devices, systems, and methods are shown and described. In one embodiment, the device includes an access door that is generally repositionable about a maintenance opening in a compression chamber. A chamber maintenance assembly may include a repositionable chamber access door, a pair of opposing hydraulic actuators, and a pair of extension arms connecting the access door and the hydraulic actuators. The result is devices, systems, and methods to provide improved access to the compression chamber to attend to jamming maintenance.
    Type: Grant

  • Publication number: 20050126328
    Abstract: The invention provides a steering assembly (10, 10a) including a first shaft (28, 28a) having a first longitudinal axis (29, 29a). The steering assembly (10, 10a) also includes a second shaft (32, 32a) having a second longitudinal axis (33, 33a). The first and second longitudinal axis (29, 29a, 33, 33a) are transverse and offset with respect one another. The first and second shafts (28, 28a, 32, 32a) are engaged at an intersection (35, 35a) such that the second shaft (32, 32a) translates along the second longitudinal axis (33, 33a) in response to rotation of the first shaft (28, 28a) about the first longitudinal axis (29, 29a). The steering assembly (10, 10a) also includes a bearing member (34, 34a, 34b, 34c) contacting the second shaft (32, 32a). The bearing member (34, 34a) is moveable along a bearing axis (37, 37a) extending transverse to both of the first and second longitudinal axis (33, 33a) at the intersection (35, 35a) to support the second shaft (32, 32a).
