Pipe saddle assembly

Claim 2

A boss saddle valve construction for making a valve controlled connection to a fluid passage formed transversely into a pipe line comprising a flexible strap to be disposed about the pipe, the ends of said strap being disposed at the side of the pipe, valve means formed with a flow passage therein to be aligned with said fluid passage, a resilient seal between the bottom of the valve means and that annular margin of the pipe encircling said fluid passage, a pair of rigid fulcrum elements carried by said valve means and extending along the pipe, readily attachable means disposed across said fulcrum elements for interconnecting the ends of said strap, and means for tightening said strap about the pipe to compress said seal between said valve means an the pipe, the last named means acting upon the fulcrum elements to localize the application of forces thereto to compress said seal while evenly distributing compressive forces about the pipe periphery via said strap.

Claim 3

A boss saddle valve construction for making a tightly sealed valve controlled connection to a fluid passage formed transversely into a pipe line comprising a flexible strap to be disposed about the pipe, the ends of said strap being disposed at the side of the pipe and folded reversely under to dispose the end of the strap between the pipe and the strap, lugs disposed in the folds and formed to include projecting portions having bolt-receiving passages therein, valve means formed with a flow passage therein to be aligned with said fluid passage and including a pressure portion at the lower end thereof, a resilient seal between the bottom of said portion and that annular margin of the pipe encircling said fluid passage, a pair of rigid elements carried by said valve means and extending along the pipe, bolts in said bolt-receiving passages and engaging said rigid elements for interconnecting the ends of said strap thereacross, and means at said side of the pipe for tightening said strap about the pipe to bind each of the underfolded ends of the strap between its associated lug and said pipe while compressing said seal between said pressure portion and the pipe via forces applied to said rigid elements to localize the application of forces thereto to compress said seal while evenly distributing compressive forces about the pipe periphery via said strap.

Claim 4

A boss saddle valve construction for making a tightly sealed valve controlled connection to a fluid passage formed transversely into a pipe line comprising a flexible strap to be disposed about the pipe, the ends of said strap being disposed at the side of the pipe and folded reversely under to dispose the end of the strap between the pipe and the strap, lugs disposed in the folds and formed to include projecting portions having bolt-receiving passages therein, valve means formed with a flow passage therein to be aligned with said fluid passage and including a pressure portion at the lower end thereof, a resilient seal between the bottom of said portion and that annular margin of the pipe encircling said fluid passage, a pair of rigid elements carried by said valve means and extending along the pipe, bolts in said bolt-receiving passages and engaging said rigid elements for interconnecting the ends of said strap thereacross, and means at said side of the pipe for tightening said strap about the pipe to bind each of the underfolded ends of the strap between its associated lug and said pipe while compressing said seal between said pressure portion and the pipe via forces applied to said rigid elements to localize the application of forces thereto to compress said seal while evenly distributing compressive forces about the pipe periphery via said strap.

Claim 5

A boss saddle valve construction for making a tightly sealed connection to a fluid passage formed transversely into a pipe line comprising a flexible band to be strapped about the pipe, the ends of said strap being disposed atop the pipe, valve means including a pressure portion formed with a flow passage therein to be aligned with said fluid passage, a resilient seal between the bottom of said portion and that annular margin of the pipe encircling said fluid passage, a pair of rigid elements carried by said valve means and extending along the pipe for receiving compressive sealing forces locally applied thereto, readily attachable means for interconnecting the ends of said strap across said rigid elements, and means atop the pipe threadedly movable between advanced and retracted positions with respect to said pressure portion for drawing said rigid elements radially away from said pipe for tightening the strap about the pipe to compress said seal between said pressure portion and the pipe, the last named means acting upon said portion via the rigid elements to localize the application of forces thereto to urge said portion straight against said seal.

Claim 6

A boss saddle valve construction for making a tightly sealed connection to a fluid passage formed transversely into a pipe line comprising a flexible band to be strapped about the pipe, the ends of said strap being disposed atop the pipe, valve means including a pressure portion formed with a flow passage therein to be aligned with said fluid passage, a resilient seal between the bottom of said portion and that annular margin of the pipe encircling said fluid passage, a pair of rigid elements carried by said valve means and extending along the pipe for receiving compressive sealing forces locally applied thereto, readily attachable means for interconnecting the ends of said strap across said rigid elements, and means atop the pipe threadedly movable between advanced and retracted positions with respect to said pressure portion for drawing said rigid elements radially away from said pipe for tightening the strap about the pipe to compress said seal between said pressure portion and the pipe, the last named means acting upon said portion via the rigid elements to localize the application of forces thereto to urge said portion straight against said seal.

Claim 7

A unitary valve assembly for making direct connection to a fluid passage formed transversely into a pipeline comprising a flexible strap to be disposed about the pipe, boss means formed with a flow passage to be aligned with said fluid passage, a resilient sealing element disposed between the bottom of the boss means and that annular margin surface of the pipe encircling said fluid passage, said boss means including an annUlar compression element formed to include a portion of said flow passage, said compression element having an undersurface for pressing against said sealing element and a force-receiving portion formed thereabove, a valve having an exteriorly threaded, hollow, elongate body portion forming a flow passage therein, said exteriorly threaded body portion bearing against said force-receiving portion, a collar formed with rigid fulcrum elements each having a narrow support edge extending in the direction of the pipe, said collar being threaded onto said body portion for rotation relative thereto, means interconnecting the ends of the strap disposed across said fulcrum elements, said collar threadedly encircling said threaded body portion to be drawn upwardly therelong during rotation of said body portion while said collar is held from rotating by said interconnecting means disposed across said fulcrum elements.
