Abstract:
A manually controlled chain driver apparatus for a bicycle drive chain derailer providing necessary forward chain movement less power transmission to bicycle pedals for derailer operation during stopping and coasting instances when pedaling motion has ceased or is not possible.

Claim (Index 7):
7 - A bicycle derailer chain driver apparatus comprising:\n a) a bicycle rear wheel hub drive chain derailer, b) said bicycle drive chain in constant engagement with one of a plurality of a bicycle rear wheel hub power transmission drive chain sprockets, c) said rear wheel hub slaved to a pawl and ratchet assembly through attachment to ratchet hub thereof embodying a plurality of ratchet pockets and internally housing a rotating pawl hub fitted with a corresponding plurality of pawls of predominantly circular midsections urged in outward radial direction by means of a corresponding plurality of compression springs and adapted for engagement with said plurality of ratchet pockets, d) said pawl hub including a radial extension retaining said pawls between a corresponding plurality of axial inner and outer gib extensions between mating concentric circular peripheries, including mating features limiting inward and outward radial movement of said pawls and embodying said corresponding plurality of compression springs urging said pawls in outward radial direction, and an axial extension internal and rotationally secured to said bicycle rear wheel hub power transmission drive chain sprockets, e) said plurality of pawls further adapted for engagement with said ratchet pockets upon forward actuation of bicycle pedals, resultant forward movement of said drive chain and forward rotation of said bicycle rear wheel hub power transmission drive chain sprockets, f) a pawls collapsing and drive chain driving apparatus including an electrically powered chain driver motor, a thereto connected power transmission means with an affixed rotary connection to a power transmission cam hub concentric to said pawl hub and including a radial extension embodying a plurality of cams serving to draw said pawls in inward radial direction through mating recessed features thereof, in turn forcing corresponding rotation of said pawls, said pawl hub, thereto retained said bicycle rear wheel hub power transmission drive chain sprockets and said drive chain upon said pawls reaching end of respective inward radial travel thereof, g) a pedals forward clutching apparatus fitted for actuation of said drive chain upon a forward pedaling motion and slip upon actuation of said bicycle drive chain driver with said pedals in a predominantly stationary state, h) a power pack for energizing said electrically powered chain driver motor, and g) a rider power switch for actuating said electrically powered chain driver motor, Whereby upon need to operate said bicycle derailer along with inability to alternate said bicycle pedals, rider triggers said chain driver power switch thereby energizing said electrically powered chain driver motor forcing rotation of said cam hub, collapse of said pawls, disengagement to said rear wheel drive hub, rotation of said pawl hub and thereto retained said rear wheel hub power transmission drive sprockets, forward movement of said drive chain in turn enabling the rider to actuate said bicycle drive chain derailer with said pedals forward clutching apparatus providing desirable slip action of said drive chain thereby circumventing power transmission thereof to said pedals of said bicycle.
