Abstract
Abstract An adjustable wheel bracket assembly which includes a relatively stiff wheel axle crank and a relatively flexible spring steel adjusting lever keyed to the crank is provided with tension producing mechanism to take up the tolerance and eliminate play in the assembly. The tension producing mechanism comprises a warp formed in the spring steel lever and a clamp to exert pressure on the warp and thus create tension in the system to hold the assembly together without play.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
In an adjustable wheel bracket assembly including a relatively stiff wheel axle crank, a relatively flexible adjusting lever keyed to the crank, a backup plate and detents with respect to which the lever is flexed in the course of adjusting lever position, the improvement to bias the lever and crank together under tension and thus to take up tolerance and eliminate play in the assembly and comprising a clamp for pressing the lever and crank together, said lever having a warp yieldable under clamp pressure to create tension in the lever and bias the assembly together withOut play between the assembled parts, said clamp comprising a bushing having an end face which engages the backup plate and a shoulder spaced from said face and in engagement with one of said crank and lever.
Claim 2
Dependent Claim
