Claim 2

A manual control means for operating a speed change gear and a brake for a bicycle which comprises a mounting plate fixed on a bicycle frame, a shaft protruded from one side of the mounting plate, a wire reel rotatably mounted on said shaft, a first wire secured at one end to said wire reel and at the other end to the speed change gear, said manual control means being rotatably mounted in said shaft and including a base having a working element, a second wire having one end thereof connected to the brake, said working element arranged to transfer said second wire, a main hand lever body secured to said base, a means for selectively transmitting the rotary movement of said main hand lever body, said means comprising a connecting element moving along with said main hand lever body to transmit the rotary movement thereof to said wire reel when said connecting element moves in one direction, but when it moves in the other direction, said connecting element releases the rotary movement of said main hand lever body.

Claim 3

A manual control means for operating a speed change gear and a brake for a bicycle which comprises a mounting plate secured to a bicycle frame, a shaft protruded from one side of said mounting plate, a wire reel of disc shaPe rotatably mounted in said shaft, said wire reel including an arciform channel formed adjacent the outer periphery thereof, a notch provided in the intermediate portion of said channel, said wire reel forming a narrow slot on one side thereof, a first wire having one end connected within the narrow slot of said wire reel and the other end connected to the speed change gear, a second wire having one end connected to the brake, a hand operable lever rotatably mounted on said shaft including a base provided with a working element for transferring said second wire connected to the brake, said hand operable lever comprising a main hand lever body secured to said base, a means movable with said main hand lever body and including a rodlike portion which moves along with the main hand lever body and has an engagement portion at one end thereof, and said engagement portion passing through the arciform channel of said wire reel and being displaceable therein into engagement with said notch in said channel.

Claim 4

A manual control means for operating a speed change gear and a brake for a bicycle which comprises a mounting plate secured to a bicycle frame, a shaft protruded from one side of said mounting plate, a wire reel of disc shaPe rotatably mounted in said shaft, said wire reel including an arciform channel formed adjacent the outer periphery thereof, a notch provided in the intermediate portion of said channel, said wire reel forming a narrow slot on one side thereof, a first wire having one end connected within the narrow slot of said wire reel and the other end connected to the speed change gear, a second wire having one end connected to the brake, a hand operable lever rotatably mounted on said shaft including a base provided with a working element for transferring said second wire connected to the brake, said hand operable lever comprising a main hand lever body secured to said base, a means movable with said main hand lever body and including a rodlike portion which moves along with the main hand lever body and has an engagement portion at one end thereof, and said engagement portion passing through the arciform channel of said wire reel and being displaceable therein into engagement with said notch in said channel.

Claim 5

A manual control means for operating a speed change gear and a brake for a bicycle, as set forth in claim 2, wherein said main hand lever body comprises a hollow lever body fixed on said base, a means for releasably transmitting the rotary movement of said main hand lever body in operative engagement with said rodlike portion, said rodlike portion disposed within the hollow portion of said main lever body, and said means for releasably transmitting the rotary movement comprising a knob secured to the end of said rodlike portion spaced from the end containing said engagement portion and spring biased away from said engagement portion.

Claim 6

A manual control means for operating a speed change gear and a brake for a bicycle, as set forth in claim 2, wherein said rodlike portion being disposed in spaced relationship with and arranged to move axially relative to said main hand lever body, a means for releasably transmitting the rotary movement of said main hand lever body comprising a pushbutton mounted on the opposite end of said rodlike portion from its engagement portion, and a spring biasing said pushbutton away from said engagement portion.

Claim 7

A manual control means for operating a speed change gear and a brake for a bicycle, as set forth in claim 1, wherein an indicator being rotatably secured to said mounting plate, said indicator comprising a rotary cylinder having an indicating portion for displaying the shift of the speed change gear and an indicating means, a means interconnecting said rotary cylinder and said main hand lever body for transmitting the movement of said main hand lever body to said indicating means, and said indicating means having abbreviated signs thereon for indicating both the change speed and the shifted brake.
