Wheel and winch assemblies utilizing identical hubs and axles in a toy construction set

In a toy construction set, a block adapted to be attached to other blocks, an axle projecting from one side of said block, a hub member having a bore therein of greater length than that of the axle so that said axle extends only partway through said bore, said hub member being spool-shaped and having a cylindrical rim at each end thereof, means releasably retaining said axle within said bore, and a crank unit having means thereon engageable with one of said cylindrical rims, said means on said crank unit including a plurality of angularly spaced spring fingers extending from a crank disk inside larger diameter rim, each of said spring fingers having a lip at the free end thereof for resiliently bearing against the inner surface of said one rim.

In a toy construction set, a plurality of special blocks adapted to be attached to other blocks, an axle projecting from one side of each of said special blocks, and a plurality of identical spool-shaped hubs having a bore therein, means for releasably engaging said axles to retain at least a portion of said axles within said bores, a tire on at least one of said hubs to provide a wheel assembly, a crank unit on another of said hubs to provide a winch assembly, and locking means having a shank portion extending through said crank unit and shiftable into obstructive through which said shank portion extends and the cross section of said shank portion also being noncircular to prevent rotation of said crank unit relative to said locking means.

In a toy construction set, a plurality of special blocks adapted to be attached to other blocks, an axle projecting from one side of each of said special blocks, and a plurality of identical spool-shaped hubs having a bore therein, means for releasably engaging said axles to retain at least a portion of said axles within said bores, said axles extending only partway through said bores, a tire on at least one of said hubs to provide a wheel assembly, and a crank unit on another of said hubs to provide a winch assembly, said crank unit provided for engaging a portion of said hub.

In a toy construction set, a block adapted to be attached to other blocks, an axle projecting from one side of said block, a hub member having a bore therein of greater length than than of the axle so that said axle extends only partway through said bore, said hub member being spool-shaped having a rim at each end thereof, said hub member having an ear with a hole therein for the attachment of one end of a cord, a crank unit having means thereon engageable with one of said cylindrical rims, and means releasably retaining said axle within said bore, said releasably retaining means including an annular rib in said bore, and said axle having a longitudinal slot therein so as to form a pair of resilient legs, the free end portions of which legs have grooves formed therein for receiving segments of said rib.
