Abstract
Official abstract text for this publication.
A sprocket guard assembly comprising a sprocket having sprocket radial spokes, and having teeth on an outer perimeter, the teeth disposed in a plane CL1, each sprocket radial spoke communicating with a first cylindrical surface, a circular member having circular member radial spokes, and each circular member radial spoke communicating with a second cylindrical surface, a collar having an outer cylindrical surface, a fastener engaging the collar, the first cylindrical surface and the second cylindrical surface engaging the outer cylindrical surface, all coplanar in a plane CL2, and plane CL1 is offset from plane CL2.
First claim
Opening claim text (preview).
We claim: 1. A sprocket guard comprising: a sprocket having sprocket radial spokes, and having teeth on an outer perimeter, the teeth disposed in a first plane (CL 1 ); each sprocket radial spoke communicating with a corresponding first cylindrical surface; a circular member defining an axis and a second plane (CL 2 ) perpendicular to the axis; the circular member having circular member radial spokes, and each circular member radial spoke communicating with a corresponding second cylindrical surface; a collar having an outer cylindrical surface; and a fastener engaging the collar; wherein the first plane (CL 1 ) is parallel to and offset from the second plane (CL 2 ); and the first cylindrical surface and the second cylindrical surface engaging the outer cylindrical surface, all extending axially from the second plane (CL 2 ) to the first plane (CL 1 ). 2. The sprocket guard as in claim 1 , wherein the teeth engage an endless member. 3. The sprocket guard as in claim 1 , wherein the teeth engage a belt. 4. The sprocket guard as in claim 1 , wherein the fastener is threaded. 5. The sprocket guard as in claim 1 , wherein the sprocket comprises a recess for receiving the collar.
