1 shows the angle measuring tool 10 which comprises a measuring slide 20 and a measuring base 30. The distal end of the first elbow part is inserted into the second part until it bottoms against or abuts the stop, providing an elbow of fixed included angle.įIG. ![]() An internal stop is provided within the second elbow part. The first elbow part can be precut to a desired included angle within a pipe system and inserted into the proximal end of the second elbow part. The second elbow part has the same radius of curvature as the first elbow part. The distal end of the first part has a constant radius of curvature which fits into the proximal end of the second elbow part. The proximal end of the first elbow part and the distal end of the second elbow part are contemplated to accommodate standard pipes and fittings. The preferable pipe elbow comprises two parts, each with a proximal, or upstream end, and a distal, or downstream end. 1, 1997 in the name of Byrnes, incorporated herein by reference. An ideal elbow is that disclosed in the U.S. The pipe elbows best suited for use with the current invention are elbows designed to be cut to a required angle. The angle measuring tool 10 and the angle marking tool 40 are intended for use in measuring and marking pipe elbows.
