Abstract
Abstract A two-piece exhaust system clamp assembly includes a flexible wire clamp wrapped around an exhaust system component and having a threaded shank at one end thereof which is inserted through an eyelet formed at the other end. A shouldered nut is rotatably journalled in the eyelet and threaded over the shank to apply a clamping force about the circumference of the component.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
186 words
In a motor vehicle exhaust system, a two-piece clamp assembly for mounting an exhaust system component comprising: a contractible clamp formed from a single piece of flexible wire, said clamp including an intermediate section defining a first loop having an inner periphery engageable with the surface of the component, said clamp having a straight first end disposed tangential to said first loop and having a threaded shank formed thereon, said clamp further having a circular eyelet formed at the other end disposed tangential to said first loop, said eyelet including a closed loop having a free end overlapping said first loop and defining an opening normal to the first loop and registering with said first end and into which said threaded shank is received; and an internally threaded shouldered nut engaging said shank having a bushing end journalled in the opening of said closed loop and having an annular flange bearing against the closed loop, said nut having a head section adapted to be engaged by an adjusting tool whereby adjustment of said nut contracts the first loop to apply a clamping load against said component.
