Patent ID: 8286513

Claim:
A water sampling device, comprising: a cylinder; a first disk positioned at a top of the cylinder; a plurality of sampling tubes attached to the first disk; a second disk positioned on the first disk, wherein the second disk includes an aperture through which water to be sampled flows into one of the plurality of sampling tubes when the aperture is lined up with an opening of the one sampling tube, wherein the cylinder is submerged to allow the water to be sampled to flow through the aperture, wherein the second disk rotates to line up the aperture with the opening of the one sampling tube; a timing mechanism controlling rotation of the second disk the timing mechanism comprising; a first conductive strip; a second conductive strip, wherein the second conductive strip is perforated by a plurality of apertures creating non-conductive spaces between non-perforated portions of the second conductive strip; a first contact contacting the first conductive strip; and a second contact alternately contacting the second conductive strip and the non-conductive spaces; and a motor for rotating the second disk, wherein the motor is disengaged when the second contact contacts a non-conductive space.
