 Sampler Imbedded in Coal 



3671(b) 



SAMPLER, "comTeco" Reliable Coal Sampler. Decidedly practical for coal 

 sampling from cars and piles. Devised so as to sample coal that is 3 inches 

 or smaller in diameter. The simple construction makes it practical and easy 

 to operate. 



The cut shows the sampler imbedded in the coal. The sample has been 

 extracted from top to bottom of the coal as it lies in the car. This is the 

 true way of obtaining a thoroughly representative sample. The pipe thus 

 surrounds the sample and keeps it intact until it is withdrawn from the 

 coal. Then, by reversing the spiral, the sample of coal is emptied into a 

 receptacle suitable for that purpose. The teeth at the bottom of the pipe 

 act as "grippers," thus keeping the pipe from turning. These, together 

 with the spiral, act also as a "clipper" and shear off pieces of coal that 

 wedge between.
