` To atl whom it may cancern:

Be it known that we, Enron T. CHRISTEN- snN and DAVID M.

A pipe-coupling comprising similar eylindrieal sleeves having llaring outer ends, and provided on their adjacent` inner ends with ilangeseXt-ending in a plane inclined to the axial line of said sleeves, each flange being provided with a series of apertures evenly disposed lroin each other, and adapted to register with the apertures ol the adjacent flange, bolts engaging said apertures and clamping said y'lai'iges together, set-rings holted to the outer ends oli said sleeves independently ol" each other, and provided with an inner diameter extending flush with the inner diameter .of the respective sleeves, substantially as shown 'and deseriliei'l.

2. A pipe-coupling comprising similar cvlindrical sleeves having'lilaring outer ends, and provided on their adjacent inner cnds with flanges extending in a plane inclined to the axial line of said sleeves, cach llangc being provided with a series olE apertures evenlv disposed troni each other and adapted to .register with the ajiertures ol the adjacent llange, holtsengaging said apertures and elamping said llangcs together, rings bolted to the outer ends ol' said sleeves independently ol eachother and having their inner Wall extending llnshwith the inner wall of said sleeves, and constructed in sections adapted to be adjusted laterally relatively to each other, i'i'ieans l'or elainping the sections of said. rings together7 and lor securing said ring lto the end ol the inljacent. sleeve, substantially as shown and described.

3.
