Gas sampler

Claim 1

A device for retrieving fluid samples from a flow line having access ports provided therein, an comprising shank means adapted for selective engagement with the access ports, tube means carried by the shank means and reciprocal with respect thereto, fluid passageway means provided in said tube means and having at least one open end for selective communication with the interior of the flow line, said open end being movable to substantially any desired transverse position within the flow line for admitting fluid samples into the fluid passageway from substantially any desired cross-sectional area of the flow line, and valve means carried by the tube means for selectively opening the fluid passageway for directing the fluid sample from the interior of the flow line to the exterior of the tube means, said shank means comprising an externally threaded stem, and said tube means being provided with complementary threaded means for engagement with the threaded stem to provide said reciprocation therebetween.

Claim 2

A device for retrieving fluid samples from a flow line having access ports provided therein, an comprising shank means adapted for selective engagement with the access ports, tube means carried by the shank means and reciprocal with respect thereto, fluid passageway means provided in said tube means and having at least one open end for selective communication with the interior of the flow line, said open end being movable to substantially any desired transverse position within the flow line for admitting fluid samples into the fluid passageway from substantially any desired cross-sectional area of the flow line, and valve means carried by the tube means for selectively opening the fluid passageway for directing the fluid sample from the interior of the flow line to the exterior of the tube means, said shank means comprising an externally threaded stem, and said tube means being provided with complementary threaded means for engagement with the threaded stem to provide said reciprocation therebetween.

Claim 3

A device for retrieving fluid samples from a flow line having access ports provided therein, and comprising shank means adapted for selective engagement with the access ports, tube means carried by the shank means and reciprocal with respect thereto, fluid passageway means provided in said tube means and having at least one open end for selective communication with the interior of the flow line, said open end being movable to substantially any desired transverse position within the flow line for admitting fluid samples into the fluid passageway from substantially any desired cross-sectional area of the flow line, and valve means carried by the tube means for selectively opening the fluid passageway for directing the fluid sample from the interior of the flow line to the exterior of the tube means, said tube means comprising an outer sleeve reciprocally secured to the shank means, and an inner tube carried by the outer sleeve and extending longitudinally through the shank means, means interposed between the inner tube and outer sleeve for providing simultaneous longitudinal movement therebetween and independent rotation movement about the longitudinal axes thereof, said inner tube being provided with said fluid passageway means extending longitudinally therebetween.

Claim 4

A device for retrieving fluid samples from a flow line having access ports provided therein, and comprising shank means adapted for selective engagement with the access ports, tube means carried by the shank means and reciprocal with respect thereto, fluid passageway means provided in said tube means and having at least one open end for selective communication with the interior of the flow line, said open end being movable to substantially any desired transverse position within the flow line for admitting fluid samples into the fluid passageway from substantially any desired cross-sectional area of the flow line, and valve means carried by the tube means for selectively opening the fluid passageway for directing the fluid sample from the interior of the flow line to the exterior of the tube means, said tube means comprising an outer sleeve reciprocally secured to the shank means, and an inner tube carried by the outer sleeve and extending longitudinally through the shank means, means interposed between the inner tube and outer sleeve for providing simultaneous longitudinal movement therebetween and independent rotation movement about the longitudinal axes thereof, said inner tube being provided with said fluid passageway means extending longitudinally therebetween.

Claim 7

A device for retrieving fluid samples from a flow line having at least one access port provided therein, and comprising threaded shank means adapted for removable engagement with the access port, a longitudinally extending bore provided in said shank means, a tube member extending longitudinally in and through said shank means and reciprocal with respect thereto, an outer sleeve concentrically arranged with respect to the inner tube and shank means, hand wheel means threadedly secured to the shank means and reciprocal therealong, means securing the outer sleeve to the hand wheel means for movement simultaneously therewith, means interposed between the inner tube and outer sleeve for providing simultaneous longitudinal movement therebetween and independent rotation movement therebetween about the respective longitudinal axes thereof, sealing means interposed between the shank means and the outer sleeve and inner tube for precluding leakage of fluid therebetween, and stop means provided on the shank means for limiting the reciprocal movement of the wheel Means therealong.

Claim 8

A device for retrieving fluid samples from a flow line having at least one access port provided therein, and comprising threaded shank means adapted for removable engagement with the access port, a longitudinally extending bore provided in said shank means, a tube member extending longitudinally in and through said shank means and reciprocal with respect thereto, an outer sleeve concentrically arranged with respect to the inner tube and shank means, hand wheel means threadedly secured to the shank means and reciprocal therealong, means securing the outer sleeve to the hand wheel means for movement simultaneously therewith, means interposed between the inner tube and outer sleeve for providing simultaneous longitudinal movement therebetween and independent rotation movement therebetween about the respective longitudinal axes thereof, sealing means interposed between the shank means and the outer sleeve and inner tube for precluding leakage of fluid therebetween, and stop means provided on the shank means for limiting the reciprocal movement of the wheel Means therealong.
