GEORGE S. ANDRUS, OF COLUMBIA, COLORADO.
SAMPLING APPARATUS.
SPECIFICATION formingpart of Letters Patent No. 280,994, dated July 10, 1883.
Application filed March 14, 1883. (No model.)
. in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a perspective view of the apparatus with the side of the case partially broken away. Fig. 2 is a detail view, showing the sup ports of the distributers. Fig. 3 is a perspective view of the hopper. Fig. 4 is a detail view of the delivery-hopper.
The inclosing-case may be of any suitable form and dimensions. A A are the ends. 13 B are hinged doors on the front and back, that give access to the boxes, and the lower part of the case is fitted with inclined boards 0, that lead to the deliveryhopper D. At the top of the case is a supply-hopper, E, provided with a damper, a, for regulating the supply of ma terial, so that it shall descend through the throat of the hopper in a compact mass the alternately right and left in the horizontal] rows, so that they shall empty one-half of them to the inside of the case and the others toward the outside. Each row is placed in such relation to the row beneath that the chutes inclining to the front come above the partitions k of the next lower chutes, equally at each side'thereof, and about midway from front to back.
The distributers or chutes are supported by saddles (Z, (shown most clearly in Fig. 2,) which are supported on brackets or otherwise on the sides A of the case, and each row is provided with two supporting bolts, 0, that extend through the sides of the case. 51
The apparatus is to be used in connection with crushers, pulverizers, stamps, or other machinery used for crushing or pulverizing ore or other materials, and also for sampling concentrates, tailings, placer-gravel, or other 6( minerals or materials, for the purpose of ascertaining the average value of such material from a sample taken by repeated subdivisions of a certain quantity. For that purpose the material to be sampled is conveyed to the 6, hopper E, the hinged damper being closed, as shown by dotted lines in Fig. 3, until the hopper is filled. The damper is then opened, as shown by full lines in Figs. 1 and 3, and the material passes through the throat of the hop- 7 per to the upper distributers F, where, by the partitions, it is divided into two equal portions, one-half passing to the inside of the case and thence to hopper D, and the remainder passing to the second row of distributers, to 7 be again divided, as before, and so on until the lower chutes are reached, where the material passing out-ward goes to a suitable receptacle.
The apparatus, as shown in Fig. 1, is pro- 8 vided with a set of distributers at each side of the case, the object being to obtain duplicate samples, which is always desirable, and in that arrangement the single row of distributers F at the top discharge both right and left into 8 distributers below. here but a single sample is required, one set of distributers only will be required. Each row may contain two or more of the chutes or distributers.
This apparatus is of inexpensive character, 9 and, being without machinery, does not require extra labor to attend it. It is accurate in'operation, as it divides every pound of material passing through it, instead of sampling one portion, and the accuracy is further assured 9 by the duplicate samples. It is durable, can i be readily repaired and adjusted, and cannotget out of order.
By placing the'apparatus between a crusher or pulverizer and the stamps or furnace, all I the ore will be accurately sampled at no extra expense, and the per cent. of value saved in treatment can be exactly determined. The clined alternately to the inside and outside of 10 4 sample may be taken from either row of chutes. the case, and thechutes of one row being di- Having thus fully described my invention, I rectly under the outwardly-inclined chutes of claim as new and desire to secure by Letters the row above it, as shown and described.
