Abstract

15,210. Exline, F., and Dawley, F. F. July 8. Paddle-wheels.-A paddle-wheel for use in the stern of a vessel is shown in sectional plan in Fig. 3. Paddle frames F, having stays f<1> and side-plates and carrying the vertical blades H, are pivoted on rods G, G' carried by eccentric wheels A, B mounted on a horizontal frame c of the form shown. Motion may be transmitted from the driving-shaft by sprocket-wheel and chain gearing to sprocket-wheels E' on the hubs E of the wheels A. In paddle-wheels for use at the sides of vessels, one of the discs A is dispensed with in each wheel, and the driving-discs of the two paddle-wheels are mounted on the driving-shaft, which is hollowed to receive the ends of the horizontal supporting- frame. The shafts of the wheels A, B may be arranged vertically over one another to enable the paddles or blades to be pivoted directly to these wheels. Fig. 8 shows a sectional elevation of a similar modification for use in the stern of a vessel, in which the two shafts S carry toothed wheels V geared together by a pinion W on a shaft W<1> mounted in bearings u<3> in a frame U, which also carries bearings u<2> for the ends of the shafts S, each of which is driven by a separate motor, the cranks being at right-angles to one another. These shafts carry radial arms connected by flat rings R<2> with raised bosses, through which pass rods R<3>, on which are pivoted strips carrying the blades or paddles. The paddles are made much narrower than the space between side wheels.
