Abstract
Abstract A fluid sampling apparatus having an elongated member which carries a pivotal platform at one end and a handle at the other end. An operating lever extends from the handle to the platform whereby a vessel attached to the platform can be pivoted by pulling the lever at the handle, thereby moving the vessel from inverted position to upright position to cause fluid at a predetermined depth or level within a body of fluid to enter the vessel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid comprising in combination, an elongated member having handle means at one end and being of such length that with said handle means above the surface of a body of fluid the other end may be positioned at a predetermined depth therein, a platform adapted to hold a vessel and pivotally mounted on said elongated member at said other end thereof to pivot about an axis at substantially right angles to said elongated member, and operating means connected relative to said platform and extending to said handle to pivot said platform and vessel thereon substantially 180°.
Claim 2
Dependent Claim
113 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid comprising in combination, an elongated member having handle means at one end and being of such length that with said handle means above the surface of a body of fluid the other end may be positioned at a predetermined depth therein, a platform adapted to hold a vessel and pivotally mounted on said elongated member at said other end thereof to pivot about an axis at substantially right angles to said elongated member, and operating means connected relative to said platform and extending to said handle to pivot said platform and vessel thereon substantially 180°.
Claim 3
Dependent Claim
46 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid according to claim 1, wherein said operating means in pivoting said platform said 180° causes said vessel to be moved from inverted to upright position in said fluid.
Claim 4
Dependent Claim
38 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid according to claim 2, wherein said operating means is actuatable at said handle means to pivot said platform said 180°.
Claim 5
Dependent Claim
55 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid according to claim 3, wherein said elongated member is formed with a transverse opening at said other end and said platform is provided with a tubular extension in said opening and pivotal therein to pivot said platform.
Claim 6
Dependent Claim
61 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid according to claim 4, wherein said operating means includes a generally reciprocatable lever extending along said elongated member and having a lower end portion connected to said tubular extension whereby reciprocating movement of said lever effects pivotal movement of said extension and platform.
Claim 7
Dependent Claim
44 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid according to claim 5, wherein said lever has an upper end portion adapted to be manually engaged and pulled to effect reciprocating movement of said lever.
Claim 8
Dependent Claim
39 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid according to claim 6, wherein said platform is provided with holding means for retaining a vessel having a generally flat base.
Claim 9
Dependent Claim
47 words
A fluid sampling apparatus for obtaining a fluid sample at a predetermined depth in a body of fluid according to claim 7, wherein said other end of said elongated member is formed with a generally flat surface at right angles to the axis of said opening therein.
