  • Patent number: 4753448
    Abstract: A rear wheel brake cable arrangement for a free style bicycle comprises a first cable connected between a rear wheel brake lever and a rocking member mounted for swiveling movement to a stem pipe, and a second cable connecting the rear wheel brake mechanism to a vertically movable member coaxially mounted on the stem pipe. Depressing of the rear wheel brake lever causes swiveling movement of the rocking member which moves a pair of links that transmit a uniform force to move the vertically movable member and thereby a rotary member along the stem pipe to cause movement of the second cable connected to the rotary member.

  • Patent number: 4753325
    Abstract: A parking brake assembly comprising a pair of brake shoes pivotally mounted on a backing plate, a brake operating lever pivoted to the brake shoe and operable by a remote cable for pivoting the brake shoes against a brake drum, and a coil spring provided under compression between the brake lever and the backing plate. During shipment of the parking brake assembly, it is attached to an axle and the coil spring has an end that extends to an opening in the back plate. The cable including a conduit and an inner member, preferably a flexible strand, is handled separately. After the parking brake assembly is attached to an automotive vehicle, the cable can be connected even though the brake drum is in place and prevents seeing the interior of the brake assembly. Specifically, the strand is then forced through the conduit and the coil.

  • Patent number: 4479658
    Abstract: The invention is a wheelbarrow which includes a hand-actuated braking system. The wheelbarrow comprises a frame, a wheel rotatably attached to the frame, a pan attached to the frame which contains the material to be transported, and a braking system which allows the user to manually apply a braking force to the wheel. The braking system employs a drum brake consisting of one or more brake shoes disposed within the hub of the wheel. A backplate encloses the brake mechanism within the hub to hinder foreign matter, such as water, mud, or oil from interposing itself between the brake shoe or shoes and the inner surface of the hub and interfering with the generation of the braking force. The braking system is actuated by means of a pivoted lever installed on the frame and linked to the brake by a flexible cable whose length can be adjusted. Legs can be attached to the bottom of the frame so that the wheelbarrow can stand unsupported in an upright position.

A brake lever is operatinely connected with the brake shoes housed in a brake drum so that the brake lever is pivoted by operation of the brake wire to outwardly expand the brake shoes to place the shoe linings into frictional engagement with a brake surface of the brake drum. The return angle of the brake lever upon a brake releasing operation is rendered constant by a stopper mechanism. The brake wire comprises an inner wire member connected to the brake lever, and an outer wire member slidably fitted over the inner member and urged by a compression spring in a direction away from the brake lever.

  • Patent number: 4351418
    Abstract: A brake compensator for a vehicle using a resilient device or resilient elastomeric material which is connected to the cable or the cable sheath of a cable-controlled brake, and is extended or compressed in response to a force applied thereon when a brake is applied. In one embodiment, the resilient device is disposed between the sheath and the frame of a vehicle, and is arranged so that the control cable passes directly through the compensator and to a brake caliper. In a further embodiment, the brake compensator may be disposed between the sections of sheath around a continuous brake cable. This arrangement avoids the need for an assembly to mount the compensator to the vehicle frame. Apparatus is shown for pre-loading the resilient device and thereby advantageously adjusting for different product and rider characteristics. Additionally, structure may be provided for limiting the maximum compression, beyond which the cable and sheath operate in a conventional manner.

  • Patent number: 4102439
    Abstract: The invention contemplates a bicycle-braking system in which the rear-wheel brake is selectively operable, in which rear wheel braking torque is the means of actuating the front brake, and further in which substantial force-amplification characterizes the actuating connection between (a) rear-wheel torque-reaction pick-off and (b) front brake actuation. Rear-wheel braking torque is noted by physical displacement against a spring, so that if front-wheel brake torque becomes so effective as to substantially reduce rear-wheel brake torque, the spring will automatically react to reduce the magnitude of front-wheel brake effort.
