Abstract

A stamped and welded clamp for pipe or tube joints having a plurality of arcuate segments pivotally attached to each other and separable at one location so as to facilitate wrapping about the joint. Each segment forms a Vee shaped recess on its inside face and each is formed from similar pieces projection welded together and having top and lateral reinforcing flanges. A special T-bolt serves to secure and tighten the assembly and employ a T-shaped bolt and which fits slidably into a mating housing having a stepped end-face to serve to restrain the bolt from turning during tightening.

Claims

1. A quick-release segmented Vee clamp for securing tubing in end-to-end gas-tight relationship, comprising a plurality of arcuate segments each being pivotaly connected to the adjacent segment and having one of the segments joined to another by means of a quick disconnect T-bolt, each segment being formed of stamped sheet metal pieces defining a Vee shaped recess therebetween and having a radialy extending flange, the pieces being welded together about the flange, and outwardly extending reinforcing means on each piece, said one of the segments having a tubular housing formed on a free end thereof, the shank of said bolt passing therethrough and having a nut threaded thereon, the said another segment having a generally rectangular housing having a height less than its width and adapted to receive the head of the T-bolt in one position of the bolt but restraining the T-bolt head from withdrawal in another position of the bolt.

2. A quick-release segmented Vee clamp as defined in claim 1, wherein the pieces are joined together by projection welding.

3. A quick-release segmented Vee clamp as defined in claim 1 and including three segments.

4. A quick-release segmented clamp as defined in claim 3, wherein the pivotal connection between adjacent segments comprises a pair of spaced ears on the end of one segment and a pair of lugs in face-to-face contact on the adjacent segment and pivot pin means passing through said ears and lugs.

5. A quick-release segmented clamp as defined in claim 3, wherein the pivotal connection between adjacent segments comprises a pair of spaced ears on the end of one segment and a pair of spaced ears on the adjacent segment, each set of ears being offset from each other, and pivot pin means passing through said ears.

6. A quick-release coupling for securing and tightening a segmented pipe or tube clamp, said clamp having a cylindrical housing on one end thereof and an oval housing on the other end thereof, threaded bolt means passing through said cylindrical housing and having a nut thereon adapted to contact the outside of the cylindrical housing, said bolt means having a T-shaped head on one end thereof adapted to slide freely through said oval housing when the T-head is oriented properly with the longer dimension of the oval housing, notch means on the outer face of said oval housing for receiving the inside face of the T-head aftre the T-head is inserted through the oval housing and rotated therein, so as to lock the bolt from further rotation during torquing of said nut.

7. A quick-release coupling as defined in claim 6, wherein a pair of notch means are provided on said outer face of the oval housing said notch means being on opposite sides of said outer face.

8. A quick-release coupling as defined in claim 6, wherein said notch means has two sides generally transverse to said outer face of the oval housing, one side being longer than the other.

9. A quick-release coupling as defined in claim 6, wherein said nut includes frictional retaining means thereon which may be used to manually rotate, insert and finally position said bolt during installation.
