  • Patent number: 10023282
    Abstract: The gears for reversing the rowing motion for oars is a gearing mechanism configured for use with an oar. The gears for reversing the rowing motion for oars reverses the pulling motion associated with the oar. This reversal of the pulling motion allows the oar to be used normally while the rower faces the bow of a boat. The gears for reversing the rowing motion for oars comprises a drive gear mechanism, a rotation gear mechanism a handle mechanism, an oar mechanism, and a gunwale mount. The drive gear mechanism transfers power from the handle mechanism to the oar mechanism. The gunwale mount attaches the gears for reversing the rowing motion for oars to the gunwale of a boat. The rotation gear mechanism raises and lowers the oar into the water.

  • Patent number: 8051940
    Abstract: A steerable vehicle knuckle has an inboard portion defining upper and lower arms, with a kingpin between them, and has an outboard portion defining a spindle that cooperates with a fluid driven motor. The arms define a cavity where an axle end portion is pivotally received. Fluid supply ports, which supply fluid to energize the motor, are located on an upper surface of the knuckle's inboard portion. Fluid drain lines extend within the knuckle from the motor to the cavity and are utilized to drain fluid from the motor. The supply ports and drain lines are each connected to separate hoses formed in a small arc that follows closely the circular curvature of the kingpin. This arrangement of port, lines, and hoses is less expensive to produce, easier to package, more robust, allows for faster steering reaction, and is easier to assemble than conventional arrangements.
