Oar-pro-pel′ler.

1. A device to imitate by machinery the action of sculling. Two submerged blades at the stern are attached to an oscillating, vertical shaft and brought broadside to the water and feathered, alternately, so as to make an effective and a return stroke. The horizontal shaft [1542]

Oar-swivel.

of the blades receives an oscillation in a vertical plane, while the sleeve to which its hub is secured is oscillated in a horizontal plane, so that it receives a double oscillation, once around its own axis and also around the axis of the vertical shaft.

In another form, the blades are oscillated with their rockframe, and are feathered, so as to move forward edgeways and move backward flatways to propel the boat.

A canal-boat, propelled by oars, was used on the Sankey Canal, Lancashire, England, in 1797. The oars made 18 strokes per minute, and were operated by a steam-engine.

1877.
