Abstract:
1. In a series of successively sized segmented pipe couplings each coupling adapted to securably connect the similarly configured and sized pipe ends of juxtaposed pipes; each one of said series of segmented pipe couplings comprising at least two arcuate segments to be assembled in arcuate end-to-end relationship for encircling the juxtaposed ends of the pipes to be coupled; each of said coupling segments including; each one of said series having a different diameter and intended to couple together two pipes having the same pipe diameter; each first segmented pipe coupling in a first one of said series having a first diameter and each second segmented pipe coupling in a second one of said series having a second diameter, said second segmented pipe couplings being the next successively sized couplings within said series after said first segmented pipe couplings, with said second diameter being greater than said first diameter, said first segmented pipe couplings being intended to couple together pipes having respective pipe diameters that are different from the respective pipe diameters of pipes that said second segmented pipe couplings are intended to couple together, wherein said coupling segments m any one of said series are identical to each other and symmetric such that each bolt pad on any coupling segment in any one of said series is alignable into a fully bolt tightened connection with any bolt pad of any other coupling segment in that one of said series, the improvement comprising:
