    • A boat propeller wherein the blades are easily removable from the propeller hub on an individual basis to permit quick replacement for repair and/or for substituting blades of different pitch comprising a hub adapted to fit over and attach to a drive shaft; a plurality of removable blades positioned around said hub and extending radially therefrom, each of said blades comprising a water engaging blade portion and a rigid tang extending from the base and of such blade portion; a plurality of blade engaging sockets disposed on and around said hub, said sockets adapted to mate with and receive the tang of said blades; and preferably a cover plate adapted to fit over the portion of said tang within said socket, tang, cover plate each being provided with a plurality of aligned bolt holes; and a plurality of bolts extending through said aligned holes and holding each assembly thereof together. Further modifications include a blade assembly for use wherein less force will be exerted, e.g. an electric trolling motor drive, wherein the bolts may be substituted by a spring-loaded button retainer for the blade and the provision of folding blades to permit easier and safer storage of the propeller when off the drive shaft.
    • 一种船用螺旋桨,其中叶片可以单独地从螺旋桨轮毂移除,以允许快速更换修理和/或替代不同桨距的叶片,其包括适于装配并附接到驱动轴的轮毂; 多个可移除刀片,其围绕所述轮毂定位并从其径向延伸,每个所述刀片包括从所述基座和所述刀片部分延伸的水接合刀片部分和刚性柄脚; 设置在所述轮毂上和周围的多个叶片接合插座,所述插座适于与所述叶片配合并接收所述叶片的柄脚; 并且优选地,适于装配在所述插座内的所述柄脚的部分上的盖板,每个脚板盖板设置有多个对准的螺栓孔; 以及多个螺栓,其延伸穿过所述对准的孔并将其每个组件保持在一起。 进一步的修改包括用于其中将施加较少力的刀片组件,例如, 电动拖车电机驱动器,其中螺栓可以被用于叶片的弹簧加载的按钮保持器代替,并且提供折叠刀片以允许在离开驱动轴时螺旋桨更容易和更安全地存储。
