摘要： 2894. Martin, J. H. Feb. 5. Endless - chain motors. - An endless - chain water-current motor is fitted with vanes that feather when out of the water, lateral deflectors for directing the stream upon the vanes, and a floating forward deflector for deflecting floating debris. The motor proper comprises two parallel floats 1, 2, carrying a framework upon which four sprocket-wheels 6 carrying two chains 8. These chains are connected across by spindles 7 carrying V-shaped vanes 18. A ratchet mechanism on each vane prevents backward rotation. Forward rotation, for feathering and unfeathering, is effected at each end of the machine by a standing ratchet engaging a pinion carried on each spindle 7. The chains have lateral wheels 28, Fig. 3, running between rails 25, 26. Deflecting-boards 34 direct the lateral stream upon the vanes. Power is taken off the sprocket-wheel spindle 4. The motor is chained to a device comprising two floats 43 carrying a framework wherein is a shallow float 50 capable of vertical movement. The float 50, while too shallow to interfere materially with the flow of the stream, suffices to deflect any floating matter likely to injure the vanes.
