Abstract: A mechanism for opening and closing an angularly movable panel, comprising a drive box for attachment to a fixed frame, the drive box housing a cable wheel rotatable upon translation of a control cable when in operative association therewith, a chaincase having a sprocket operatively connected with a chain located in a casing, the chain being for attachment at one end to an angularly movable panel, rotation of the sprocket effecting translation of the chain into, or out of, the casing in accordance with the sense of sprocket rotation, the chaincase being mountable in any of four different positions on the drive box.

Abstract: A ship's steering unit comprising a housing, a cable wheel mounted within the housing, a shaft with a pinion thereon in driving engagement with the cable wheel, and a one-piece body which serves as a bearing support for the shaft, the shaft having a shroud portion providing a member for mounting the unit to a support surface, which when the unit is orientated with its housing lowermost is spaced below the upper region of the shaft and the bearing support therefor.

Abstract: An operator mechanism for translating the core of a cable having a casing guiding the core, comprising a cable wheel mounted for rotation inside a housing, the cable wheel being adapted for attachment of the core to a defined region of the periphery thereof so that the core, when so attached, will, at its attached area, be rotatably fast with the peripheral region of the cable wheel, a handle for rotating the cable wheel, the handle being positioned outside the housing and adjacent a forward end face thereof, the handle being capable of operative securement with respect to the cable wheel in any of a plurality of angular orientations relative thereto about the axis thereof.

Abstract: A motion transmitting unit comprising a housing, a cable wheel mounted within the housing, a shaft with a pinion thereon in driving engagement with the cable wheel, and a onepiece body which serves as a bearing support for the shaft, the shaft having a shroud portion providing a member for mounting the unit to a support surface, which when the unit is orientated with its housing lowermost is spaced below the upper region of the shaft and the bearing support therefor.
