Abstract
Abstract A coupling for pipe or the like made up of a plurality of spaced generally hollow cylindrical bodies made of sheet material and each having their adjacent ends bent back on themselves forming a pocket along each edge, an outrigger bar extends through the pocket on one edge of each of the bodies and a short bar extends through the pocket on the outer edge of each body. The short bars are connected to the outrigger by means of bolts and a flexible liner is supported inside each of the bodies forming a gasket for surrounding a pipe extending through the bodies. In the second embodiment a basic difference is that the couplings are made up of clamps or outrigger clamps at two halves rather than in a single band.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
252 words
A coupling comprising a first clamp body, a second clamp body, said clamp bodies being made of a first flat piece of material and a second flat piece of material, said flat pieces of material each having a first end and a second end and being curved into a general cylindrical shape, first pockets formed on said first ends, second pockets formed on said second ends, an outrigger bar extending through said first pockets for holding said first clamp body and said second clamp body in spaced relation to each other, a first bar means extending through said second pocket on said first clamp body, said first bar means having a plurality of holes extending therethrough, a second bar means extending through said second pocket on said second clamp body, said second bar means having a plurality of holes extending therethrough, holes in said outrigger bar, holes in said pockets, and first bolts extending through said holes in said outrigger bar and said first pocket of said first clamp body and through said holes in said first bar means and said second pocket of said first clamp body, for clamping said first clamp body, second bolts extending through said holes in said first pocket of said second body, and said outrigger bar and through said holes in said second bar means and said second pocket of said second clamp body, for clamping said second body whereby said first body and said second body are held in spaced clamped relation from one another.
Claim 2
Dependent Claim
252 words
A coupling comprising a first clamp body, a second clamp body, said clamp bodies being made of a first flat piece of material and a second flat piece of material, said flat pieces of material each having a first end and a second end and being curved into a general cylindrical shape, first pockets formed on said first ends, second pockets formed on said second ends, an outrigger bar extending through said first pockets for holding said first clamp body and said second clamp body in spaced relation to each other, a first bar means extending through said second pocket on said first clamp body, said first bar means having a plurality of holes extending therethrough, a second bar means extending through said second pocket on said second clamp body, said second bar means having a plurality of holes extending therethrough, holes in said outrigger bar, holes in said pockets, and first bolts extending through said holes in said outrigger bar and said first pocket of said first clamp body and through said holes in said first bar means and said second pocket of said first clamp body, for clamping said first clamp body, second bolts extending through said holes in said first pocket of said second body, and said outrigger bar and through said holes in said second bar means and said second pocket of said second clamp body, for clamping said second body whereby said first body and said second body are held in spaced clamped relation from one another.
Claim 3
Dependent Claim
134 words
The coupling recited in claim 1 wherein a third clamp body is provided made of a third flat piece of material having a first end and a second end, a first pocket on said first end and a second pocket formed on said second end, holes in said first pocket, a third short bar, a hole in said second pocket, a hole in said third short bar, said outrigger bar extends through said first pocket of said third body and said third short bar extends through said second pocket of said third body and third bolt means extends through holes in said said first pocket, outrigger bar, second pocket and said third short bar whereby said first clamp body, said second clamp body and said third clamp body are held in spaced clamped relation.
Claim 4
Dependent Claim
43 words
The coupling recited in claim 1 wherein said pockets are formed by bending said ends of said flat pieces of material outwardly generally perpendicular to said cylindrical shape, then bending said flat material back on itself about a radius thereby forming said pockets.
