SAMPLER, Hand, Braun Umpire—The buckets revolve in opposite directions, and each bucket is divided into four parts, two closed and two open. The sample is halved in the upper bucket and again in the lower, allowing one-quarter of the original to fall into the receptacle. Re-feeding the quarter obtained gives one-sixteenth of the original, and again re-feeding, a sixty- fourth is obtained, etc.
A cam on the crankshaft agitates the hopper by striking a strap, which is attached to the hopper with a coiled spring, and by means of an eccentric lever the force of the blows may be varied at will. The upper and lower buckets may be quickly removed, and all portions are readily accessible for cleaning, making it impossible to salt subsequent samples.
