Abstract
Abstract An elongated member has a short depending leg at one end and a pair of longer legs diverging from the other end. The pipe to be laid is suspended from the elongated member between the diverging legs. Adjusting structure is disposed on the frame to move the suspended pipe axially. Also, the structure will individually adjust vertically the ends of the pipe when the frame has been lowered to rest upon the bottom of the body of water where the pipe is to be laid.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
173 words
An apparatus for the laying of a plurality of end to end and connectable pipe sections underwater comprising an elongated frame member having a first generally vertical leg at one end and a pair of individually adjustable ground engaging legs diverging from said elongated member at the other end thereof together forming an inverted V, said first leg being of fixed length and shorter Than said pair of legs, cable means for suspending a section of pipe from said frame between said pair of legs, winch means on said frame for moving said suspended pipe section axially, winch means on said frame for selectively adjusting vertically each end of the suspended pipe section, and an arcuate positioning guide at the end of said first leg resting upon the annulus of a previously laid pipe section, providing the sole support for said frame member at said one end, the supporting of the frame member by said legs permitting said suspended section to be axially aligned with and connectable to said previously laid pipe section.
Claim 2
Independent Claim
173 words
An apparatus for the laying of a plurality of end to end and connectable pipe sections underwater comprising an elongated frame member having a first generally vertical leg at one end and a pair of individually adjustable ground engaging legs diverging from said elongated member at the other end thereof together forming an inverted V, said first leg being of fixed length and shorter Than said pair of legs, cable means for suspending a section of pipe from said frame between said pair of legs, winch means on said frame for moving said suspended pipe section axially, winch means on said frame for selectively adjusting vertically each end of the suspended pipe section, and an arcuate positioning guide at the end of said first leg resting upon the annulus of a previously laid pipe section, providing the sole support for said frame member at said one end, the supporting of the frame member by said legs permitting said suspended section to be axially aligned with and connectable to said previously laid pipe section.
Claim 3
Dependent Claim
23 words
An apparatus as claimed in claim 1 wherein said winch means is controlled by means disposed on said frame adjacent said first leg.
