Sprocket wear template
First Claim
1. Apparatus for gauging the wear of a toothed sprocket, said apparatus comprising a body defining first, second and third spaced peaks on the outer surface thereof, said apparatus being positioned so that with such a sprocket in a relatively less worn state, the first and third peaks may be brought into contact with adjacent flanks of adjacent teeth of a sprocket with the second peak positioned in the root area of the sprocket between the adjacent flanks, but with the second peak removed from contact with the sprocket, and with such a sprocket upon which sufficient wear has taken place, the first and third peaks may be brought into contact with the adjacent flanks of adjacent teeth of such a sprocket, bringing the second peak into contact with the sprocket in the root area of the sprocket between the adjacent flanks, and wherein the body further defines a fourth peak on the outer surface thereof, spaced from the first, second and third peaks, said apparatus being positioned so that with another differently sized toothed sprocket in a relatively less worn state, the second and fourth peaks may be brought into contact with adjacent flanks of adjacent teeth of such differently sized sprocket with the third peak positioned in the root area of the differently sized sprocket between the adjacent flanks thereof, but with the third peak removed from contact with such differently sized sprocket, and with such a differently sized sprocket upon which sufficient wear has taken place, the second and fourth peaks may be brought into contact with adjacent flanks of adjacent teeth of such differently sized sprocket, bringing the third peak into contact with the differently sized sprocket in the root area thereof between the adjacent flanks thereof.

Abstract
Apparatus for gauging the wear of a toothed sprocket includes a flat body defining a plurality of peaks about the periphery thereof. A pair of such peaks are brought into contact with adjacent flanks of adjacent teeth of the sprocket, and another peak, intermediate the pair of peaks, is brought adjacent the root area of the sprocket between such adjacent flanks, so that wear of a sprocket in such area can be observed.
