ABSTRACT:
An improved liquid sampling device comprising a liquid trough having a liquid inlet end and a liquid discharge end with a liquid sample receptacle disposed below the liquid discharge end for receiving liquid samples through an open top portion of the liquid sample receptacle into the interior thereof. The liquid sample receptacle is rotatably supported below the liquid discharge end of the liquid trough whereby the liquid sample receptacle is rotatable between a first position with the open top portion thereof open to one side and a second position with the open top portion thereof open upwardly such that liquid falling into the open top portion from the liquid discharge end of the liquid trough is collected in the interior of the liquid sample receptacle. A first receptacle actuating device is provided for rotating the liquid sample receptacle from the first position to the second position thereof in response to the liquid falling from the liquid discharge end of the liquid trough, and a second receptacle actuating device is provided for rotating the liquid sample receptacle from the second position to the first position thereof in response to a reduction in the rate of liquid falling from the liquid discharge end of the liquid trough.
