  • Patent number: 8366085
    Abstract: A locating pin assembly is provided. The assembly includes a body and a cylinder assembly for moving a ram in a reciprocally linear manner. A bearing is coupled to the ram and configured to engage a bearing wedge to reduce “play” between the ram and the assembly. Illustratively, the bearing and bearing wedge reduce or substantially eliminate this “play” to prevent axial rotation of the ram.
    Type: Grant

  • Patent number: 8136803
    Abstract: An armover clamp assembly is provided that includes a housing, an actuator, a cam, a first link, a pivot pin, a driver, a rotating pin, and an arm. The cam includes a cam slot disposed therethrough and is attached to the actuator for linear movement inside the housing. The cam slot has a cam path that includes a locking portion and an extended travel portion. The first link is movably coupled to the cam slot via a cam pin coupled to the link. The cam pin is disposed in and configured to follow the cam path. The pivot pin is coupled to the first link at a position spaced apart from where the cam pin is coupled to the link. The driver is pivotally attached to the pivot pin. The rotating pin extends exterior of the housing and is attached to the driver inside the housing at a location spaced apart from the pivot pin.

  • Patent number: 7150563
    Abstract: A formed bearing assembly and a method of making the bearing is provided. The bearing assembly includes a housing and a bearing space formed therein. A slide is disposed within the bearing space and is movable along its longitudinal extent. A bearing is formed in the bearing space between the housing and the slide. The bearing is a solid, formed in the bearing space while in liquid state. At least a portion of the bearing forms the shape of at least a portion of the slide.
