Abstract:

A rear wheel hub and chainless drive train gear assembly for use on a bicycle having an axle bracket fixed to the frame of the bicycle, a spindle extending axially through the axle bracket and left and right pedal crank arms for rotating the spindle upon application of a pedaling force. A primary drive gear fitted to the spindle drivingly engages carrier gears which operate a planet gear cage housing and a multiple planetary gear and sun gear arrangement according to various gear ratios determined by selective operation of a clutch assembly. Planetary gear groups each include an integral set of planetary gears of varying size which mesh with corresponding sun gear rings. Operation of the clutch assembly serves to selectively engage pawl stops with a corresponding sun gear ring, thereby engaging the corresponding sun gear ring with one of the planetary gears of the planetary gear groups according to a selected gear ratio. The planetary gear groups drive an annular gear ring and an associated annular needle bearing which, in a forward clockwise rotation, engages the hub body to rotate the rear bicycle wheel. Reverse rotation of the annular gear, in a counter-clockwise rotation, results in a freewheeling of the drive train gear assembly relative to the hub body.

Abstract:

A game of skill includes a playing board having a perimeter surrounding a playing area divided into equally sized boxes, wherein each box is marked with an identifying element, such as a geometric shape and/or symbol of a particular color. The identifying elements dictate the permitted direction of movement of corresponding playing pieces along avenues formed by the arrangement of identifying elements within the boxes. Scoring points are indicated at the juncture of four box corners, identifying the center of four adjacently positioned boxes in a square area. The playing pieces are provided in contrasting colors to identify each player. Each player is provided with four sets of playing pieces, the playing pieces in each set being of a particular group to identify the permitted movement of the playing pieces of that group. Each player is further provided with scoring pieces of contrasting color. When a scoring point is surrounded on three sides (i. e.
