Abstract
Abstract To separate each of a plurality of samples of a fluid from a body of the fluid and deposit each sample into a different one of a plurality of bottles, the downwardly extending outlet of a funnel, being offset from a vertical axis of rotation of the funnel, orbits step-by-step in a circle around the vertical axis above a distributing plate as the funnel rotates to guide fluid into each of a plurality of separated inlets in the distributing plate as the fluid is pumped from the body of the fluid through intake and funnel hoses and into the large, circular upwardly extending inlet of the funnel, with the outlet of the funnel hose being positioned at a fixed location lying along an imaginary circle the downward projection of which lies within the inlet of the funnel. To guide the samples from the funnel outlet into separate bottles, the distributing plate includes a circle of inlets beneath the orbit of the funnel outlet to receive the samples and two concentric circles of outlets, with each outlet: (1) communicating with a different inlet through a passageway, which passageway extends in a different direction from the inlet than the two adjacent passageways, so that the the inlets are all in one central circle between the two circles of outlets; and (2) being positioned over the open end of a different bottle, with the bottles forming two circles of circumferentially-spaced bottles.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
155 words
A liquid sampler for sampling liquids from within a sewerage system comprising: a substantially cylindrical casing of small enough size to fit through a sewerage manhole; said casing including at least a substantially cylindrical vertical outer wall and bottom wall defining a bottle holding compartment; means for drawing fluid containing sewage into said casing and depositing it into at least one bottle; a substantially cylindrical ice compartment centered within said bottle holding compartment; said casing including first, second and third sections; said means for drawing fluid including control programming means for automatically controlling the time said fluid is drawn in accordance with a predetermined program; said first section containing said bottle holding compartment and means for distributing said fluid to a plurality of different bottles; said second section being mounted on top of said first section and containing said control programming means; and said third section being an inverted cover fitting over said second section.
Claim 2
Dependent Claim
155 words
A liquid sampler for sampling liquids from within a sewerage system comprising: a substantially cylindrical casing of small enough size to fit through a sewerage manhole; said casing including at least a substantially cylindrical vertical outer wall and bottom wall defining a bottle holding compartment; means for drawing fluid containing sewage into said casing and depositing it into at least one bottle; a substantially cylindrical ice compartment centered within said bottle holding compartment; said casing including first, second and third sections; said means for drawing fluid including control programming means for automatically controlling the time said fluid is drawn in accordance with a predetermined program; said first section containing said bottle holding compartment and means for distributing said fluid to a plurality of different bottles; said second section being mounted on top of said first section and containing said control programming means; and said third section being an inverted cover fitting over said second section.
Claim 3
Dependent Claim
38 words
A liquid sampler according to claim 1 further including section fastening means for fastening said sections with a sufficiently close fit to permit immersion of said liquid sampler for short periods of time without leakage into the sampler.
Claim 4
Dependent Claim
18 words
