  • Patent number: 9932097
    Abstract: Disclosed herein is a trimmable pod drive assembly that includes a pod drive unit having a transmission assembly secured to a steering unit, a gear case assembly coupled to and rotatable by the steering unit about a steering axis, and a propeller rotatable about a propeller driveshaft axis extending through the gear case assembly so as to generate thrust along a thrust vector. The trimmable pod drive assembly further includes a trim assembly secured to the pod drive unit in a manner allowing for rotation of the pod drive unit about a trim axis that is substantially perpendicular to the steering axis, wherein actuation of at least one component of the trim assembly causes movement of the pod drive unit and the thrust vector about the trim axis.

  • Publication number: 20130273792
    Abstract: An outboard motor for a marine vessel application, transmission devices for such an outboard motor, and related methods of making, operating, and modifying attributes of same, are disclosed herein. In at least one embodiment, the motor includes a horizontal-crankshaft engine in an upper portion of the motor, positioned substantially above a trimming axis of the motor. In at least another embodiment, first, second and third transmission devices are employed to transmit rotational power from the engine to propeller(s). In at least a further embodiment, the motor is made to include a rigid interior assembly formed by the engine, multiple transmission devices, and a further structural component. In further embodiments, the motor includes numerous cooling, exhaust, and/or oil system components, and/or other transmission features. In at least some additional embodiments, a transmission device of the motor is configured to facilitate gear ratio variation and/or includes an integrated oil pump.

  • Patent number: 6179004
    Abstract: A vacuum holder for use with an automated carton erecting and packing line and mountable on a rotary carton placer for removing cartons into which product is to be placed includes vacuum cup for removing a carton from a store of cartons. The cartons including a foldable flap. The vacuum holder includes a set of vacuum cups that will engage a flap and at an appropriate time in the carton erection sequence will be positively actuated under control of a power actuator to fold the flap to a desired position prior to depositing the carton on a conveyor line. A rotary manifold carries both vacuum for vacuum cups holding the carton, and fluid pressure for the power actuators to the rotating carton placer.

  • Patent number: 5579895
    Abstract: A crosspush conveyor moves cans laterally of a can conveyor into cartons that are also moving at the same speed as the can conveyor. The crosspush conveyor is mounted on a pair of sprockets that support roller chains to form two straight lengths, with the lengths being positioned at an angle relative to the direction of movement of the can conveyor. A plurality of paddles or pushers are mounted onto the chain conveyor and are pivotally mounted so that they can pivot away from a working position as they move through a selected portion of their path of travel. The paddles are supported in a working position on guide rails to hold the pusher members so that they will move cans laterally of the can conveyor on one side of the conveyor. The crosspush conveyor operates without a separate control cam for holding the crosspush members in position throughout the travel of the conveyor.
