The first and second clamp members each include a first clamp jaw and a second clamp jaw longitudinally spaced from the first clamp jaw. Each one of a first plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the first clamp member, and each one of a second plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the second clamp member. An assembly made from a kit of components is also disclosed. The kit includes an apparatus for aligning sections of pipe, and a plurality of shoe inserts. The assembly includes the apparatus and at least two of the shoe inserts coupled with the apparatus. ## Claims ### Claim 1 An apparatus for aligning sections of pipe, the apparatus comprising: a first clamp member comprising a first clamp jaw and a second clamp jaw longitudinally spaced from the first clamp jaw; a second clamp member hingedly coupled with the first clamp member, the second clamp member comprising a first clamp jaw and a second clamp jaw longitudinally spaced from the first clamp jaw; a first turnbuckle assembly and a second turnbuckle assembly, wherein each turnbuckle assembly comprises a first clevis, a second clevis, a rod, and a torquing member secured to the rod, wherein each clevis is threadedly engaged with the rod; and a turnbuckle lug having a first portion and a second portion, wherein the second portion is integral with and extends away from the first portion, wherein the second portion is T shaped, wherein the first portion is coupled with the first turnbuckle assembly, and wherein the second portion is coupled with the first clamp jaw of the first clamp member; wherein each one of the first clamp jaw and the second clamp jaw of the first clamp member, and each one of the first clamp jaw and the second clamp jaw of the second clamp member, comprises a first frame and a second frame spaced apart from the first frame by one or more spacers; wherein the first turnbuckle assembly is coupled with each one of, and is adjustable to vary the longitudinal spacing between, the first clamp jaw and the second clamp jaw of the first clamp member; and wherein the second turnbuckle assembly is coupled with each one of, and is adjustable to vary the longitudinal spacing between, the first clamp jaw and the second clamp jaw of the second clamp member. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the torquing member of the first turnbuckle assembly comprises a nut having a polygonal shape, and having a first end surface and a second end surface spaced from the first end surface. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the nut is positioned midway between the first clevis and the second clevis of the first turnbuckle assembly. ### Claim 4 (depends on 2) The apparatus of claim 2, wherein the first end surface of the torquing member of the first turnbuckle assembly is spaced apart from the first clevis of the first turnbuckle assembly by a first distance; and the length of the first clevis of the first turnbuckle assembly is greater than the first distance. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the turnbuckle lug further comprises a rectangular insert and a first post which is integral with said rectangular insert. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the turnbuckle lug further comprising a second post integral with said rectangular insert. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the first post and the second post extend away from opposite sides of the rectangular insert. ### Claim 8 (depends on 6) The apparatus of claim 6, wherein the first post and the second post each have a rectangular cross-sectional shape. ### Claim 9 (depends on 1) The apparatus of claim 1 further comprising: a threaded member extending through a solid portion of the first clevis and into selective engagement with the first portion of the lug. ### Claim 10 (depends on 1) The apparatus of claim 1, further comprising: a first hinge, wherein the first clamp jaw of the first clamp member and the first clamp jaw of the second clamp member are pivotally coupled with the first hinge; and a second hinge, wherein the second clamp jaw of the first clamp member and the second clamp jaw of the second clamp member are pivotally coupled with the second hinge; wherein each of the first clamp member and the second clamp member is pivotable between an open position and a closed position. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the torquing member of the first turnbuckle assembly comprises a nut having a polygonal shape, and having a first end surface and a second end surface spaced from the first end surface. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the nut is positioned midway between the first clevis and the second clevis of the first turnbuckle assembly. ### Claim 13 (depends on 11) The apparatus of claim 11, wherein the first end surface of the torquing member of the first turnbuckle assembly is spaced apart from the first clevis of the first turnbuckle assembly by a first distance; and the length of the first clevis of the first turnbuckle assembly is greater than the first distance. ### Claim 14 (depends on 10) The apparatus of claim 10, wherein the turnbuckle lug further comprises a rectangular insert and a first post which is integral with said rectangular insert. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the further comprising a second post integral with said rectangular insert. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the first post and the second post extend away from opposite sides of the rectangular insert. ### Claim 17 (depends on 15) The apparatus of claim 15, wherein the first post and the second post each have a rectangular cross-sectional shape. ### Claim 18 (depends on 10) The apparatus of claim 10 further comprising: a threaded member extending through a solid portion of the first clevis and into selective engagement with the first portion of the lug.
