Abstract
18,668. Pardella, J., and Penkalla, F. Aug. 29. Oars.-A semicircular plate, moved edgewise through the water, has the after portion b enlarged so that it may act as a stop for the hinged portions c, d. During the propelling stroke, these portions of the oar are at right-angles to the plate, and, during the backward stroke, are closed against it, as shown. Fig. 1 shows a boat fitted with this oar, which is simply reciprocated, the necessity of lifting it out of the water at the backward stroke being obviated.
