Abstract:
A load indicator for use with a railway car hand brake that is connected to a railway car brake rigging comprising a housing, a plurality of levers pivotally mounted in the housing, each of the plurality of levers having a first end and an opposite second end, a plate coupled to each of the plurality of lever second ends, wherein the plate is moveable with respect to the housing, and a plurality of springs each operatively coupled between a respective one of the plurality of lever first ends and the housing. At least one of the plurality of lever first ends is moveable between a first position in which tension exerted on the plate from the railway car hand brake is within a predetermined range, and a second position in which tension exerted on the load indicator from the railway car brake rigging is outside the predetermined range.
Abstract:
A brake pad assembly includes a shank with a brake pad connected to a first end thereof and the shank extends through a support frame, a first positioning member, a brake arm, a second positioning member, a holding member and is threadedly connected to a nut. The first positioning member and the second positioning member are located on two opposite sides of the brake arm and each of which has two lugs which are retained in a hole of the brake arm. By the lugs, the two positioning members can only be rotated at a limited angle in the hole of the brake arm.

Abstract:
A brake and lock device includes a lever pivotally connected with a fork of a bicycle, a brake shoe attached to the lever for braking a wheel and a lock attached to the lever for locking the wheel. The lock includes a core for receiving a key and a latch connected with the core for locking the wheel. The core includes a first end for receiving the key and a second end connected with the latch. The first end of the core defines a keyhole. The core includes a mandrel extending from the second end thereof for connection with the latch. The latch defines a recess for receiving the mandrel and two holes in communication with the recess. The mandrel defines a hole. A pin can be inserted through the holes defined in the latch and in the mandrel. The latch may include a protective sleeve mounted thereon. The mandrel can be rotated so that the latch can be pivoted to interfere with spokes of a wheel mounted in the fork.
Abstract:
A brake device for a bicycle includes a control portion disposed to a front fork of the bicycle, the control portion having a bottom with a tubular element extending therefrom and a first piston received therein with a first resilient element disposed between the first piston and the bottom, hydraulic liquid received between the first piston and the bottom, two pipes respectively communicated with a space filled with hydraulic liquid and connected to a corresponding brake part disposed at the front fork, an actuating device slidably received in the control portion and operated by the brake cable so as to push the first piston toward the bottoms the brake part having a second piston received therein with a rod extending therefrom which has a brake pad disposed at a distal end thereof, a board received in the brake part and the rod extending therethrough, a second resilient element disposed between the second piston and the board such that when the brake cable is pulled to push the first piston to pressurize the hydraulic liquid into the brake part, the second piston and the brake pad are pushed to stop the bicycle.
Abstract:
A bicycle brake shoe for making press contact with a bicycle wheel rim to apply a braking force thereto. The brake shoe includes a shoe body which is elongated in the rotation direction of the wheel rim and which has a braking surface opposite to the braked surface of the rim. The shoe body also includes at least one slit extending in a direction transverse to the longitudinal dimension of the braking surface and extending inwardly into the shoe body to a predetermined depth.
Abstract:
A pedal actuated caliper brake actuating mechanism for a bicycle having a multi-gear chain drive includes an elongate lever mounted on the bicycle frame for resiliently resisted pivotal movement from a rest position about an axis generally coincident with that of the pedal driven main sproket. The lever is formed with two upwardly facing abutment surfaces closely spaced from opposite sides of the path of movement of the main sprocket teeth along the lower rear quadrant of the sprocket. An arm pivotally mounted at its lower end on the lever carries a horizontal roller at its upper end which projects above and laterally across both abutment surfaces and the sprocket tooth path. A resilient member fixed at one end to the arm carries a plate at its upper end which projects into the sprocket tooth path at an inclination such that the teeth slide past the plate during forward rotation of the sprocket and positively engage the plate and drive it downwardly upon reverse rotation of the sprocket. Downward movement of the plate pivots the arm to shift the roller below a downwardly moving tooth of the sprocket which in turn drives the roller into engagement with the abutment surfaces of the lever to depress the lever. Depression of the lever first actuates a mechanism to frictionally engage the rear sprocket for minimal rotation relative to the frame and then tensions a cable to apply the brake.
Abstract:
The invention relates to a rim brake for a bicycle or the like and in which the brake lining can be moved via a pivotally mounted actuating member and a support member which carries the brake lining and is movable at right angles to the rim. The actuating member is rotatable about an axis which may coincide with the axis of displacement of the support member and is connected to the support member via a threaded control such that rotation of the actuating member in one direction imparts axial movement of the support member in a direction to apply the brake lining to the rim.
Abstract:
A rim brake construction especially adapted for use with the rear wheel of a bicycle comprises a pair of brake units adapted for mounting on the bicycle frame members which straddle the rear wheel. Each brake unit has a housing pivotally and symmetrically mounted on its associated frame member. Each housing has a pair of brake lining carriers operable to move into braking engagement with the rear wheel rim in response to the application of a braking force. The lining carriers are biased by springs to a brake released position.
Abstract:
A bicycle is provided with wheels whose axle hubs are eccentric with respect to the wheel geometric center. A bicycle with such wheels and in forward motion will cause its rider to also oscillate up and down as the wheel axles rise and fall due to the wheel eccentricity. The purpose of such motions superposed on the forward travel motion is to exercise the rider's body more effectively by subjecting it to accelerations similar to those experienced in riding a horse.
