  • Patent number: 4398739
    Abstract: A splash guard to be suspended adjacent a vehicle wheel to reduce splash of liquid and slush comprises a sheet having a splash receiving surface covered with a plurality of spaced apart, discrete, elongated, stiff protuberances that are arranged in a pattern defining downward flow paths along the sheet and that direct liquid and slush thrown from the wheel into the flow paths, from which the liquid and slush can drain from the sheet. The sheet is reinforced by downwardly extending ribs which also impede sideward splashing. The protuberances and ribs are integral with the sheet. The sheet of elastomeric material is reinforced adjacent the splash receiving surface by embedded threads. The ribs are reinforced adjacent their free edges by embedded threads. The reinforcing threads resist excessive convex bending of the sheet. A guard of similar structure can be attached to the underside of a vehicle above the wheel.

    Abstract: A tire section individually securable to a wheel rim with other tire sections to form a tire so that such sections are replaceable when worn or damaged is disclosed comprising an improvement in which a substantially flexible tire section having a flat area is secured to a sealing adaptor plate through a steel ring mounting member integral with the tire section. The steel ring may be mounted in the bead of the tire, the bead facing inwardly or outwardly. Either a bolt or a clamp may be employed to secure the tire section to a flat sealing adaptor plate. The adaptor plate in turn may be mounted on a tire rim surface lying in a circumferential plane transversely extending from a wheel.
