1. An adjustable length manifold assembly, comprising:
- a rigid outer body having a bore defining a first hollow interior region;
a rigid inner body having an outer wall defining a second hollow interior region for communicating with said first hollow interior region, said outer wall having a first thread defined thereon; and
connector means for connecting said inner body with said outer body so that said inner body is rigidly held in a selectable position relative to said outer body, said connector means having an interior semicircular surface portion with a second thread defined thereon for engaging with said first thread of said inner body and said connector means being rotatable, in a first state of retention on said body, relative to said inner body for adjusting the relative positions of said inner and outer bodies and said connector means being fixed, in a second state of retention on said outer body, relative to said inner body, said connector means including;
a first yoke having a first semicircular surface and a second semicircular surface offset from said first semicircular surface;
a second yoke having a third semicircular surface and a fourth semicircular surface offset from said third semicircular surface;
hinge means for pivotally connecting said first and second yokes so that said first and third semicircular surfaces are aligned, thereby defining a first semicircular engagement surface for engaging a first portion of said outer wall of inner body, and so that said second and fourth semicircular surfaces are aligned, thereby defining a second semicircular engagement surface for engaging a second portion of said outer body; and
closure means for closing said first and second yokes to a selectable one of said first and second states of retention.

Abstract
A fluid flow system comprises a plurality of operational elements which are interconnected by rigid conduits. The present invention provides a rigid interconnecting conduit which includes a statically adjustable assembly comprising two telescopically associated members having a combined length which is variable to accommodate objects spaced at different distances and orientations. The assembly also includes a member for clamping the relatively movable elements to provide a rigid linkage once the interconnection of the objects is made.

6. A rigid adjustable length assembly for providing variable length connections between elements of a pressurized fluid flow system at a well site, said assembly comprising:
-
a first rigid pipe having a circumferential lip adjacent one end of said first rigid pipe; a second rigid pipe having a first end and a second end disposable in said first rigid pipe through said one end and further having a continuous thread defined on at least a portion of the main body of said second rigid pipe between said first and second ends; and a collar having a clamp portion for engaging said first rigid pipe adjacent said one end and having a threaded portion for engaging said thread of said second rigid pipe, said collar including; first semicircular yoke having a first semicircular, threaded surface and having a second semicircular surface radially offset from said first threaded surface; a second semicircular yoke having a third semicircular threaded surface and a fourth semicircular surface radially offset from said third threaded surface; and securing means for securing said first yoke to said second yoke so that said first and third threaded surfaces are aligned to define said threaded portion and so that said second and fourth surfaces are aligned to define said clamp portion. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
