摘要： A bicycle having front and rear wheel caliper brakes, a pedal crank assembly having a shaft extending through a hub and projecting at its ends therebeyond for connection to pedal cranks. The shaft may be integral with the pedal cranks or may be discretely formed and threadedly secured at its ends to the pedal cranks. The bicycle also contains a brake control assembly having a cam mounted on the shaft outwardly of the hub for rotation with the shaft, the cam having at least one working edge surface, a plate carried on the shaft in substantially planar parallel relationship to the cam. The plate pivotally mounts a cam follower, in the nature of a pawl, for engaging said cam working edge upon back pedalling operation. A substantially vertically extending rod is loosely engaged at its lower end to the plate and fixedly engaged in its upper end portion to brake control cables leading from the caliper brakes. The rod is journalled for axial rotation and resilient means urges the same into spaced relationship with respect to the cam follower with which the rod is engageable upon rotation for releasing the cam follower from engagement with the cam.

摘要： A bicycle having front and rear wheel caliper brake assemblies which are connected to a swingably mounted lever which in one form of the invention is operatively engaged to the pedal shaft through friction-producing elements as well as to cables controlling the brake assemblies so that upon back pedaling action the brakes will be automatically applied; but with there being a linkage connection between said lever and a pawl engageable with a driven sprocket on the rear axle to promote slackness in the transmission chain upon brake application. In another form of the invention, the particular lever member is operatively engageable with the pedal shaft by bearing elements carried thereon and to a front pawl lockable with a drive sprocket; and there being an elongated finger-like element fixed to the lever and engageable with the transmission chain for assuring of slackness therein upon release of the said front pawl. In a further form of the invention, the particular lever member is operatively connected to a pawl lockable with a driven sprocket by a cable from the front pawl, and with a spring element engaging the cable for causing slackness to develop in the transmission cable. The bicycle also incorporates a handle bar readily shiftable between touring and racing positions, as in ten-speed bicycles, and having shift controls in the ends thereof for actuation in like manner regardless of the position in which the handle bar may be disposed.

摘要： A bicycle having front and rear wheel caliper brakes connected by cables to a plate member rockably mounted on a support rearwardly of the crankshaft; there being a latch arm engaged to said plate and having a cam follower portion for engaging a cam formed on the edge of a disc cam keyed on said crankshaft for mutual interengagement upon back pedaling action whereby said latch arm is translated rearwardly with consequent rocking of said plate member to apply a rearward pulling upon said cables for braking of the bicycle. A drive sprocket is carried upon the opposed end of said crankshaft for limited relative movement with respect thereto, there being an arcuate aperture in said drive sprocket receiving a pin from the adjacent pedal crank, which pin is relatively movable within said aperture so that after braking action said crankshaft may be rotated a predetermined distance prior to engagement of the finger with the forward end of the aperture for consequent concurrent rotation, said predetermined distance being adequate for disengaging said latch arm for brake releasing action. The brake release aspect of this invention may also be used with bicycles having front free wheel systems wherein an arrangement of intermeshing teeth are provided on the drive sprocket and a sleeve to allow for requisite relative movement.

摘要： In a bicycle having the usual main shaft with a pedal crank normal thereto, a pedal assembly wherein the foot support may be in the same plane as a shaft secured to the pedal crank or below same, such latter being of the underslung type. A toe clip and a rigid support stand are provided on the pedal and being so constructed and arranged that when in disuse, the toe clip will be presented for facile insertion of the operator's foot and with the support stand in operative bicycle supporting position. In one form of the invention, a bearing structure is provided on the shaft engaged to the crank and with a plate disposed on said bearing structure to which the pedal is secured; said plate extending forwardly and rearwardly of the bearing structure and such relationship thereto as to create a counterbalance for the toe clip. In such last mentioned arrangement, the support surface comprises an arm or arms tapering in thickness from the plate adjacent portion to the plate remote portion to provide maximum ground clearance in event of tilting.

摘要： A bicycle having front and rear wheel caliper brakes each being connected by a cable to a linkage including a swingable cam element which is normally disposed in the path of travel of a cooperating cam member mounted for movement concentrically about the pedal axle whereby the cam element through its swingability is removed from such path during forward pedaling action and is lockingly engageable with such cam member upon back pedaling action. In the latter condition force is applied to the linkage for effecting a pull upon the cables to effect braking operation. The cam members are so related to the pedal cranks that when engagement with the cam element is effected one pedal crank will be downwardly directed whereby a support stand carried upon the associated pedal may cause such pedal to swing to present the support stand for engagement with the support surface.
