Abstract
Abstract Pipe clamping apparatus for use in welding the confronting ends of pipe members to one another comprises a clamping chain structure adapted to embrace one of the pipe members adjacent one end thereof and carrying a number of support members which extend axially of the pipe members and span the joint therebetween, each of the support members having adjustable members engageable with the other pipe member for maintaining the latter in axial alignment with the first pipe member. The support members carry spacing members adjustable longitudinally of the support members and operable to enter the joint between the two pipe members and space the confronting ends thereof a predetermined distance apart.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
144 words
Apparatus for use in welding to one another confronting ends of a pair of pipe members having a joint therebetween, said apparatus comprising clamp means forming a loop of such size as to encircle one of said pipe members; a plurality of elongate support members carried by said clamp means and extending axially of said loop a distance sufficient to span the joint between and engage both of said pipe members; spacer means for each of a selected number of said support members; and means mounting each of said spacer means on the associated support member for movement axially of said loop to a position in which said spacer means may overlie the joint and for movement radially inwardly of said loop to a position in which said spacer means may enter the joint and space the confronting ends of said pipe members apart.
Claim 2
Dependent Claim
144 words
Apparatus for use in welding to one another confronting ends of a pair of pipe members having a joint therebetween, said apparatus comprising clamp means forming a loop of such size as to encircle one of said pipe members; a plurality of elongate support members carried by said clamp means and extending axially of said loop a distance sufficient to span the joint between and engage both of said pipe members; spacer means for each of a selected number of said support members; and means mounting each of said spacer means on the associated support member for movement axially of said loop to a position in which said spacer means may overlie the joint and for movement radially inwardly of said loop to a position in which said spacer means may enter the joint and space the confronting ends of said pipe members apart.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1 wherein said clamp means comprises a flexible chain.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 1 including releasable latch means acting between said clamp means and selected ones of said support members for enabling adjustment of the latter relatively to said clamp means.
Claim 5
Dependent Claim
26 words
Apparatus according to claim 1 wherein the mounting meAns for each of said spacer means mounts the latter to one side of the associated support member.
Claim 6
Dependent Claim
26 words
Apparatus according to claim 1 wherein each of said spacer means comprises a member having one end thereof tapered in a direction toward said pipe lengths.
Claim 7
Dependent Claim
16 words
Apparatus according to claim 5 wherein each of said spacer means comprises a screw threaded member.
Claim 8
Dependent Claim
33 words
Apparatus according to claim 1 including at least one adjusting member carried by each of said support members for movement relative thereto into and out of engagement with one of said pipe lengths.
Claim 9
Dependent Claim
39 words
Apparatus according to claim 7 wherein a selected number of said support members carry a second adjusting member spaced from the first mentioned adjusting member and movable into and out of engagement with the other of said pipe lengths.
Claim 10
Dependent Claim
20 words
Apparatus according to claim 8 wherein the spacer means is mounted between the first mentioned and said second adjusting members.
Claim 11
Dependent Claim
19 words
Apparatus according to claim 1 wherein said mounting means comprises a harness slidable longitudinally of the associated support member.
Claim 12
Dependent Claim
80 words
Apparatus for spacing apart a pair of pipe members arranged in end to end relation with a joint therebetween said apparatus comprising an elongate support member adapted to overlie both of said pipe members and span said joint; movable spacing means for entering said joint and moving said pipe members apart; and means mounting said spacing means for movement both longitudinally of and rockably relative to said support member, said mounting means comprising a harness loosely embracing said support member.
Claim 13
Dependent Claim
80 words
Apparatus for spacing apart a pair of pipe members arranged in end to end relation with a joint therebetween said apparatus comprising an elongate support member adapted to overlie both of said pipe members and span said joint; movable spacing means for entering said joint and moving said pipe members apart; and means mounting said spacing means for movement both longitudinally of and rockably relative to said support member, said mounting means comprising a harness loosely embracing said support member.
Claim 14
Dependent Claim
42 words
Apparatus according to claim 11 wherein said support member has a longitudinal axis defining a first plane and wherein said spacing means is mounted to one side of said support member for movement in a second plane which intersects said first plane.
Claim 15
Dependent Claim
17 words
Apparatus according to claim 11 wherein said spacing means comprises an elongate member tapered at one end.
Claim 16
Dependent Claim
146 words
Apparatus for use in joining to one another confronting ends of a pair of pipe members having a joint therebetween, said apparatus comprising clamp means forming a loop of such size as to encircle one of said pipe members; a plurality of elongate support members slidably carried by said clamp means for movement circumferentially of said loop, each of said support members extending axially of said loop a distance sufficient to span the joint between said pipe members; means for releasably latching said support members in selected positions of slidable adjustment relative to said clamp means; spacer means for each of a selected number of said support members operable to enter the joint between said pipe members and space the confronting ends of said pipe members from one another; and means mounting said spacer means on the associated support members for movement longitudinally of the latter.
