 the United States Bureau of Mines and the American Society for Testing Materials. With 

 twelve divisions, each %-inch wide. Complete with four sampling pans, scoop and brush. 

 (See Journal of Industrial and Engineering Chemistry, Vol IX, No. 1, for January 1917) 116.00 



SAMPLER, Riffle, for reducing the 20 amd 60-mesh coal to a laboratory sample. Similar to No. 

 11802. but with twelve divisions each % inch wide. Complete with four sample pans, scoop 

 and brush 22-00 



SAMPLER, Braun Umpire Ore. for band power, for accurate and impartial sampling. Consists 

 of a hopper mounted on a support; two buckets, each divided into four parts, two open and 

 two closed; and a receiver. By means of gears attached to the handle the buckets are made 

 to revolve in opposite directions; with the same motion the hopper is agitated by means of 

 a cam and coiled spring. The sample is halved in the upper bucket and again in the lower, 

 allowing one quarter of the original to fall into the receptacle. Kefeeding the quarter ob- 

 tained gives ^ieth- an< l ^7 a second refeeding ^th of the original sample is obtained. All 

 parts are removable and easily accessible for cleaning. Width of sampler, 10 inches; length, 

 21 inches: height. 41 inches; shipping weight, 125 pounds 43.50 



SAMPLER, Braun Umpire Ore, for power, with tight and loose pulleys 54.00 



SAMPLER. Braun Universal, with tight and loose pulleys for power. Consists of two separa- 

 tors, which revolve in opposite directions, each divided into four parts. By this means, the 

 original sample is quartered in the upper separator, half going into the discard and half into 

 the lower separator, where the process is repeated, allowing one quarter of the original sam- 

 ple to fall into the receptacle, the rest going into the discharge chute. The hopper is mechan- 

 ically agitated by means of a cam, and is fitted with a gate to control the flow. The entire 

 machine is enclosed in a sheet iron shell and is practically dust-proof. Easily and quickly 

 cleaned, an air blast being the most convenient method. Length over all, 32 inches; width, 

 14 inches; height. 35 inches; size of pulleys, 12x2 inches; shipping weight, 220 pounds 106.00
