Abstract: A bicycle wheel rim is composed of a friction surface extending along the rim. The friction surface is provided with a plurality of action units each having a primary action area and a secondary action area and a secondary action area. The primary action area has a flat surface capable of frictional engagement with the brake shoes of a bicycle brake system. The secondary action area has a concave surface capable of frictional engagement with the brake shoes of the bicycle brake system. The action units of the bicycle wheel rim are thus capable of cooperating with the brake shoes to bring about a smooth and stable braking action for slowing or stopping the bicycle wheel in motion.

Abstract: A manually adjustable wheel for, e.g. a tractor, comprising a generally octagonal disc having four longer sides and four shorter sides, the rim having lugs to which the disc is bolted, the rim/disc bolts being arranged in pairs on the shorter sides of the disc only.

Abstract: A cast metal automobile wheel with front and rear ends, an outer annular rim portion, a radially extending intermediate disc portion, a forwardly projecting central cone portion and annular series of circumferentially spaced circumferentially and radially extending wire spokes extending from the cone and disc portions to the rim portion; the spokes have radial inner ends releasably engaged in related radially outwardly disposed openings in the cone and disc portions and have spoke nuts on their radial outer ends releasably held between the rim portion and a clamp ring screw fastened to said rim portion; the rim portion and clamp ring have flat opposing annular surface; each of said annular opposing surfaces has circumferentially spaced radially extending nut seats opposing and closed by the other of said surfaces and in which related spoke nuts are engaged and captively retained.

Abstract: An automotive vehicle wheel having a solid wheel body, provided with replaceable rows of inner and outer spokes. The spokes are purely ornamental and are readily replaceable in the event of damage. Such replaceability is made possible by providing each spoke with a longitudinally moveable mounting member. The mounting member is rotated relative to its respective spoke so as to place such spokes in longitudinal compression to hold them in place on the wheel.

Abstract: A spoked wheel is disclosed herein having a rim including a pair of circular flanges outwardly projecting from the opposite sides thereof so as to accommodate a pneumatic, tubeless tire. The rim further includes a false rim depending from the inside diameter of the rim and separated from the rim by an annular passageway. The false rim is provided with a plurality of offset and spaced apart holes for receiving spoke anchoring pins. Provided between adjacent ones of the holes, the false rim is provided with an access aperture through which replacement pins may be inserted. A removable cap covers each of the apertures when not in use.

Abstract: An improved automobile wheel with wire spokes and a novel method for making a spoked wheel. A metal spoked automotive wheel for tubeless tires having an outer circular rim with drop center adapted for receiving a tire is attached to a tubular hub assembly having means for receiving wire spokes. Wire spokes extend radially outward from the hub with terminal threads adapted for mounting a felly with threaded spoke nipples. The improved wheel center includes a narrow concentric inner felly of solid cross-section with holes for receiving the spoke nipples and peripheral portions for engaging the tire rim drop center. The felly has spaced-apart radial nipple-receiving holes and is integrally joined to the drop center of the rim at the flange.
