Abstract
Abstract A modular coupling for fluid carrying conduits or electrical conductors comprising a rectangular parallelepipedonal body formed with at least one dovetail projection on one face and at least one pair of perpendicularly intersecting conforming dovetail grooves on an opposite face for joining the coupling to a further coupling having projections and grooves of identical cross-section.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
283 words
A pipe coupling for interconnecting a pair of pipes for fluid flow from one of said pipes to the other of said pipes, said coupling comprising a body having first and second faces which face in opposite directions and having at least two other faces which face in directions different from said directions, said first face having at least one projection thereon extending transversely thereof, said projection having a cross-sectional dimension at a portion thereof spaced from said first face which is greater than the cross-sectional dimension of said projection intermediate said portion and said first face, said second face having at least a first groove and a second groove therein extending transversely of said second face and intersecting at an angle to each other, each said first and second groove having a cross-sectional shape which matches the cross-sectional shape of said projection and having a cross-sectional dimension at a portion thereof spaced from said second face which is greater than the cross-sectional dimension thereof which is intermediate said portion of said groove and said second face, whereby one said body may be interlocated with another said body by slidably inserting said projection of said one body in a said groove of said other body, said first-mentioned body also having a pair of pipe receiving openings therein, one of said openings being in one of said two other faces and the other of said openings being in one of said two other faces, and having a fluid passageway interiorly thereof extending from said one of said openings to said other of said openings for the passage of fluid therebetween, and means at each of said openings for securing a pipe to said body.
Claim 2
Dependent Claim
283 words
A pipe coupling for interconnecting a pair of pipes for fluid flow from one of said pipes to the other of said pipes, said coupling comprising a body having first and second faces which face in opposite directions and having at least two other faces which face in directions different from said directions, said first face having at least one projection thereon extending transversely thereof, said projection having a cross-sectional dimension at a portion thereof spaced from said first face which is greater than the cross-sectional dimension of said projection intermediate said portion and said first face, said second face having at least a first groove and a second groove therein extending transversely of said second face and intersecting at an angle to each other, each said first and second groove having a cross-sectional shape which matches the cross-sectional shape of said projection and having a cross-sectional dimension at a portion thereof spaced from said second face which is greater than the cross-sectional dimension thereof which is intermediate said portion of said groove and said second face, whereby one said body may be interlocated with another said body by slidably inserting said projection of said one body in a said groove of said other body, said first-mentioned body also having a pair of pipe receiving openings therein, one of said openings being in one of said two other faces and the other of said openings being in one of said two other faces, and having a fluid passageway interiorly thereof extending from said one of said openings to said other of said openings for the passage of fluid therebetween, and means at each of said openings for securing a pipe to said body.
Claim 3
Dependent Claim
41 words
A pipe coupling as set forth in claim 1, wherein said body is of rectangular parallelepipedonal form, said projection and said first and said second groove are of conforming dovetail cross-sectional and said first groove and said second groove intersect perpendicularly.
Claim 4
Dependent Claim
45 words
A pipe coupling as set forth in claim 2, wherein said first and second faces are square, said first groove, said second groove and said projection are rectilinear, said projection bisects said first face and said first and said second grooves bisect said second face.
Claim 5
Dependent Claim
82 words
A pipe coupling as set forth in claim 2, wherein said projection is rectilinear and said first face has a second rectilinear projection thereon spaced from and parallel to said first-mentioned projection, said second projection having a cross-section the same as the cross-section of said first-mentioned projection, and wherein said second face has third and fourth intersecting grooves thereon spaced from said first groove and said second groove and of the same cross-sectional shape as said first groove and said second groove.
Claim 6
Dependent Claim
83 words
A pipe coupling as set forth in claim 4, wherein said first and second faces are rectangular and have minor sides of predetermined length, wherein the spacing between said first-mentioned projection and said second projection is greater than said predetermined length, said first groove is aligned with said third groove, said second groove is parallel to said fourth groove and the spacing between said second groove and said fourth groove is equal to said spacing between said first-mentioned projection and said second projection.
Claim 7
Dependent Claim
105 words
A pipe coupling as set forth in claim 1, wherein each of said openings is adapted to receive a smooth-walled tube, and wherein said means for securing a pipe to said body comprises flexible clamp means disposed within each of said openings, and a plurality of jaws formed on said clamp means and movable into engagement with the wall of said tube, each of said openings having a wall which increases in diameter in a direction away from its associated other face for gripping said jaws of the clamp, and further comprising a sealing gasket disposed in each of said openings for engaging said tube.
Claim 8
Dependent Claim
50 words
A pipe coupling as set forth in claim 1, wherein said body has four of said other faces and wherein said body has an opening therethrough extending between two oppositely facing other faces other than said first-mentioned two other faces for receiving means for securing said body to a support.
Claim 9
Dependent Claim
20 words
A pipe coupling as set forth in claim 1, wherein both said openings are in one of said other faces.
Claim 10
Dependent Claim
37 words
A pipe coupling as set forth in claim 1, wherein one of said openings is in one of said two other faces and the other of said openings is in the other of said two other faces.
Claim 11
Dependent Claim
29 words
A pipe coupling as set forth in claim 9, wherein said one of said two other faces is at right angles to said other of said two other faces.
Claim 12
Dependent Claim
17 words
A pipe coupling as set forth in claim 9, wherein said two other faces are oppositely facing.
