Abstract

959,894. Boat propulsion. T. J. GREGORY. Jan. 2, 1962 [Oct. 5, 1960], No. 34213/60. Heading B7V. Propulsion means for a boat comprises a pair of assemblies (one of which is shown in Fig. 1) for attachment to opposite sides of the boat. Each assembly comprises a base 10 attached to the boat by bolts 11 and an aft extending paddle lever 19 pivotally mounted by means of lugs 16 and 17 about pivots 14 and 15 on the arms of a rigger bracket 13. At the free end of the lever 19 is disposed a paddle 21 which is pivoted about a vertical axis 20 and contained between stops 22 so as to be capable of movement over an arc of about 60 degrees relatively to the lever 19. A bell-crank lever 28 having a handle 29 and pivoted to the base 10 at 27, is connected to the lever 19 by a link 24 and pivots 23, 25 so as to be capable of oscillating the lever 19 over an arc of approximately 60 degrees relatively to the fore-and-aft axis of the boat. The arms 28 may be connected to a vertical lever pivoted to the boat keelson and oscillatable in a vertical fore-and-aft plane.
