Abstract
A spacer block for dual inner and outer tire carrying rims having a medial portion with a depending keeper tang for selective positioning within a keeper groove on the spoke ends of a wheel.
Claims6
A spacer block for dual inner and outer tire carrying rims when mounted on a wheel:
- said wheel having a hub element, a plurality of spokes extending radially of said hub, and an axially oriented surface on the outer end of each spoke extending inwardly from the face of a spoke to intersect a beveled inner rim mounting surface;
- said wheel further having a spacer block keeper groove on said outer end of each spoke formed radially inward from said axially oriented surface between a spoke face and a beveled surface;
- said wheel further carrying a plurality of bolt supported clamp lugs for seating and locking said spacer block and said dual rims on the wheel after mounting, each said clamp lug having a beveled outer rim mounting surface;
- said spacer block having a medial portion with a radially inward surface coincident with an axially oriented surface on said end of each spoke and parallel sides each carrying axially projecting flanges adapted for engagement with and seating under rim gutter flanges on said outer and inner rims, during tightening of said clamp lugs;
- said spacer block medial portion further having a transverse bar with a depending keeper tang projecting radially inwardly from said transverse bar for selective positioning within a keeper groove on the end of a spoke.

A spacer block for dual inner and outer tire carrying rims when mounted on a wheel:
- said wheel having a hub element and plurality of spokes extending radially of said hub, each said spoke being hollow and having an open end bounded by parallel axially oriented surfaces, said parallel surfaces extending inwardly from the outer face of a spoke to intersect a beveled inner rim mounting surface;
- said wheel further having a spacer block keeper stop projecting axially outwardly from the rear wall of a spoke and between said parallel surfaces;
- said wheel further carrying a plurality of bolt supported clamp lugs for seating and locking said spacer block and said dual rims after mounting, each said clamp lug having a beveled rim mounting surface;
- said spacer block being quadrilateral with two parallel sides defining a trapezoid;
- said spacer block having a medial portion with a radially inward surface coincident with the parallel axially oriented surfaces on said open end of each spoke, said parallel sides of said medial portion each carrying axially projecting flanges adapted for engagement with rim gutter flanges on said inner and outer rims, during tightening of said clamp lugs;
- said spacer block medial portion further having a transverse bar with a depending keeper tang projecting inwardly for selective positioning against a keeper stop within said open end of each spoke.
