Abstract
The present invention relates to a pipe clamping tool assembly that may be extended to an open position such that a portion of a pipe may be laid across a lower first member, after which said pipe clamping tool assembly may be folded to a closed position wherein a second member overlies the inserted pipe and is aligned directly over said lower first member, and by actuating a lever arm the second member is engaged and pressed downwardly such that said second member and said first member cooperate to squeeze and compress the pipe so as to clamp the same and effectively close the pipe and prevent fluid from passing through the clamped area.
Claims4
A pipe clamping tool assembly for clamping and effectively closing a pipe or the like, comprising:
- a generally elongated first member having an arcuate shaped upper pipe receiving surface for receiving a portion of a pipe to be clamped;
- first and second arm means secured to opposite portions of said first member and extending therefrom;
- a generally elongated second member having an arcuate shaped lower pipe engaging surface formed thereon and movably mounted to said first arm means and movable back and forth between a first pipe loading position where a pipe or a portion thereof can be easily placed adjacent the upper engaging surface of said first member and a second pipe clamping position generally overlying said first member such that in operation a pipe receiving area is defined between said first and said second members and the pipe to be clamped or a portion thereof is disposed between said first and second members;
- and pipe clamping lever means movably mounted to said second arm means and movable with respect thereto for engaging said second member and for pressing the same downwardly towards said first member such that said pipe or portion thereof lying in said defined pipe receiving area between said first and second members is clamped and effectively closed about the area thereof lying between said first and second members, said lever means having a pressing portion that includes a roller rotatively mounted in association therewith so as to engage a portion of said second member during the clamping operation and to press thereagainst as said lever means is actuated by pivoting the same towards said second member.
A pipe clamping tool assembly for clamping and effectively closing a pipe or the like, comprising:
- a generally elongated first member having an arcuate shaped upper pipe receiving surface for receiving a portion of a pipe to be clamped;
- first and second arm means secured to opposite portions of said first member and extending therefrom with both said first and second arm means each including a pair of spaced apart plates secured about opposite sides to said first member;
- a generally elongated second member having an arcuate shaped lower pipe engaging surface formed thereon and movably mounted to said first arm means and movable back and forth between a first pipe loading position where a pipe or a portion thereof can be easily placed adjacent the upper engaging surface of said first member, and a second pipe clamping position generally overlying said first member such that in operation a pipe receiving area is defined between said first and said second members and the pipe to be clamped or a portion thereof is disposed between said first and second members;
- and pipe clamping lever means movably mounted to said second arm means and movable with respect thereto for engaging said second member and for pressing the same downwardly towards said first member such that said pipe or portion thereof lying in said defined pipe receiving area between said first and second members is clamped and effectively closed about the area thereof lying between said first and second members, and wherein said pipe clamping lever means is pivotably connected by a transverse axis across the respective plates of said second arm means and includes a locking block disposed generally adjacent the pivot axis thereof and wherein roller means is rotatively mounted within said locking block for engaging an upper surface of said second member during the pipe clamping operation such that said second member is pressed against the underlying pipe or portion thereof until said locking block and roller means are disposed in an over center locking relationship relative to said second member and the pivot axis of said pipe clamping lever means.
