Abstract
Abstract The invention concerns coupling of a control pressure line to larger diameter well tubing, as by a coupling comprising: A. A C-shaped metallic retainer body adapted for lateral connection about the tubing, B. SAID BODY FORMING A LONGITUDINALLY EXTENDING RECESS, C. ELASTOMER MEANS AT THE INNER SIDE OF THE RETAINER BODY FOR RECEPTION IN SAID RECESS TO BE COMPRESSED BETWEEN THE BODY AND THE LINE IN RESPONSE TO SAID LATERAL CONNECTION OF THE RETAINER BODY ABOUT THE TUBING.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
In apparatus for coupling a control pressure line to relatively substantially larger diameter well tubing that extends longitudinally, the combination comprising: a. a C-shaped metallic retainer body adapted for lateral connection about the tubing, b. said body forming a longitudinally extending local recess at the inner side of the body, c. resilient elastomer means at the inner side of the retainer body and bridging the recess at the inner side thereof to be stretchably deflected outwardly toward the interior of the recess by the line and in response to said lateral connection of the retainer body about the tubing, whereby the elastomer means will resiliently urge the line toward the tubing, d. the body metal being of generally uniform thickness and bulging outwardly and locally to form said recess, and latch terminals on the retainer body and spaced from said recess and adapted to be interconnected at the side of the tubing opposite said recess.
Claim 2
Dependent Claim
155 words
In apparatus for coupling a control pressure line to relatively substantially larger diameter well tubing that extends longitudinally, the combination comprising: a. a C-shaped metallic retainer body adapted for lateral connection about the tubing, b. said body forming a longitudinally extending local recess at the inner side of the body, c. resilient elastomer means at the inner side of the retainer body and bridging the recess at the inner side thereof to be stretchably deflected outwardly toward the interior of the recess by the line and in response to said lateral connection of the retainer body about the tubing, whereby the elastomer means will resiliently urge the line toward the tubing, d. the body metal being of generally uniform thickness and bulging outwardly and locally to form said recess, and latch terminals on the retainer body and spaced from said recess and adapted to be interconnected at the side of the tubing opposite said recess.
Claim 3
Dependent Claim
24 words
The combination of claim 1 including said tubing and line, the elastomer means stretched in the recess to urge the line against the tubing.
Claim 4
Dependent Claim
33 words
The combination of claim 1 wherein said elastomer means comprises a rubber sheet extending in lining relation at the inner side of the retainer and within the recess from loci proximate said terminals.
Claim 5
Dependent Claim
20 words
The combination of claim 1 including protective elastomer structure extending at the exterior of the metallic retainer and connected thereto.
Claim 6
Dependent Claim
25 words
The combination of claim 3 including rubber lips connected to said sheet and located at the exterior of the retainer proximate longitudinally opposite ends thereof.
Claim 7
Dependent Claim
19 words
The combination of claim 1 wherein said recess is sized to pass another line paralleling the first mentioned line.
Claim 8
Dependent Claim
9 words
The combination of claim 6 including said other line.
Claim 9
Dependent Claim
44 words
The combination of claim 1 wherein latch strips are attached to body edge portions proximate a split formed thereby, the latch terminals formed by the strips which stand out radially from a generally cylindrical locus defined by the body to receive coupling force aPplication.
