The backing plate has two rear flanges each being L-shaped and having an inner portion depending from its inner surface and a rearwardly projecting outer tongue portion, these rear flanges being sized to pass through the apertures in the brake shoe platform. Also, the backing plate has two front flanges, each having an inner portion depending from its inner surface and an outer tongue portion, these front flanges being arranged to slide into the recesses at the front edge of the platform.

Abstract: A bicycle brake shoe assembly including multiple brake pads of different braking compounds replaceably inserted sequentially into a truncated pad holder. The pads have an overlap at one end and an under-lap at the other end such that upon assembly within the holder an overlap portion is mated over an under-lap portion. The pads are captured and retained in place in the truncated holder by a removable end cap. The overlap/under-lap pad mating cooperates with the pad holder and end cap to prevent pad pull out because of wheel rim movement forces on the pads. The brake shoe assembly has a transverse curvature substantially in conformance with the radius of curvature of the bicycle wheel rim, thereby improving pad contact with the wheel rim.

Abstract: A light-weight brake shoe for a rotary disc brake having a removable and replaceable friction pad. The brake shoe provides a thin-walled backing plate having a side wall for cooperatively engaging the friction pad. The side wall of the backing plate has a pair of raised lip portions for cooperatively engaging a complementary groove provided in the bottom wall of the friction pad. An irregularly shaped spring cooperatively engages a tapered groove provided in the top wall of the friction pad for biasing the friction pad into cooperative engagement with the side wall of the backing plate. The tapered groove of the friction pad provides a downwardly and inwardly biasing force in order that the friction pad maintains cooperative engagement with the side wall of the backing plate while also ensuring that the friction pad avoids dragging on the brake rotor of the vehicle when the brake is not activated.

Abstract: A latch retaining spring with clip for securely locking a brake shoe on a brake head carrier of a disc brake assembly for railway vehicles. The wire clip includes a coiled loop portion having a first straight leg section extending from one end thereof. A reverse turned portion extending from the other end of the coiled loop portion and terminating in a second straight leg portion. The first straight leg portion is inserted into a through hole formed in one of two lugs carried by the brake head carrier and into an aligned through hole formed in a pivotal latch member. The second straight leg portion inserted into a through hole formed in another of the two lugs carried by the brake head carrier.

Abstract: The present invention provides a pad retaining plate assembly which can be operated to allow for pad replacement without any part having to be removed and without the inconvenience of having to deal with nuts, bolts, etc. The pad retaining plate assembly comprises a latch member which is movable relative to a guide, the guide being secured to a brake shoe so that the latch member can then attain an operative position wherein the latch member projects through an aperture in the brake shoe. A spring also mounted on the brake shoe is arranged to grip the latch member and to hold the latch member in the said operative position when this position is attained. The latch member can be moved away by a simple tool against the grip of the spring to facilitate pad replacement.

Abstract: An improvement in mounting brake shoes on disk brakes for railroad cars in which securing member is mounted beneath the open ended groove in the brake assembly to which the shoe is mounted. The securing member moves a predetermined longitudinal distance after being unbolted from the brake assembly, is pivotable relative thereto. The securing member has an anchoring pin protruding therefrom on which a brake shoe may rest as it is being lowered from the brake assembly so that a single person can change a heavy brake shoe without fear of injury.

Abstract: The present invention provides a brake pad retaining plate assembly which is a sub-assembly which can be simply bolted to the plate of a brake shoe assembly. This sub-assembly basically comprises a retaining plate which has a pair of bolts screwed into parallel bores in one end of the plate, the shafts of the bolts extending through aligned bores in first and second plate members. A spring engages over the shaft of each bolt and engages against the retaining plate, biassing the plate members towards the heads of the bolts; the plate member nearest to the retaining plate being adapted to be secured to the shoe plate. Thus the brake pad retaining assembly of the present invention can be mounted simply by bolting the plate member nearest the retaining plate, to the shoe plate. Further, the retaining plate can only be released by engaging a suitable tool between the plate members. Thus accidental release cannot occur.
