Abstract

137,007. Jaccard, A., and Koff, J. June 6, 1919. Driving-gear. - A hand - carried screw fan having folding blades is actuated by a toothed wheel train d, r, c, a ratchet wheel e and a lever f fixed to it, and a finger lever g engaging the lever f and pivoted on the fan spindle c<1>. When not in use, the three fan blades lie over one another, but when the shaft is rotated they separate and their positions are determined by three pins projecting from the framework a sufficient distance to engage the first, second and third blades respectively.
