I cover both sides of zthe `wheel l them "by" the fori` near the periphery with sieves, or perfora l l tions in wood, sheet orcast metal; or I cover t h both sides of the wheel with planksJsheet or A cast metal, and leave a concentric opening of t h t h 55 one quarter of an inchmore or less, through wheel@ thenxbeing` in which theredueed matter can pass out of troduces jthe gold1 l which has remained on the perforated part of the gutter No. 1 over the two'incline'd gutters No. 3 and No. 4L into the inner part of the wheel or receiver. The only parts of 'the receiver with which the clay, cement, etc.

comesin contact, are the arms of the wheel, the cover of the two sides, the door and the perforated metal; The clay, cement etc. fall on the perforated metal represented in the Section by the line a b c and in the model by a piece of perforated metal covering about 1; of the inner surface. In consequence of the rotary or circular motion and the friction with the inner parts of the wheel, the clay, cement, etc. are reduced to mud and pass with the gold through the openings out of the wheel intoV ordinary sluices, where the mud and sand pass 0E and the gold remains. By the velocity of the wheel as well as through the openingY around the center the quantity of stones or fragments in the wheel can be ascertained and, when necessary, are discharged through the door in the periphery of the Wheel and removed and treated in the same way as coarse gravel mixed with stones and containing fine or coarse gold or both. VIt may be stated here, that if there is a scarcity of water, say one inch only, a quantity insuflicient for any mining operation', thata box with water maybe placed belowthe wheel and large enough to keep the Vlower part of the wheel under water. If the wheel is then set in motion by some other power, the result will be the same, that is to say: mud, clean pieces of rocksv and whatever gold there may be. One inch of water will then be used with advantage to washthe gold out from material of such light consistency and aggregation. Taking 20 inches of water for one sluice head at 2 dollars per day, the expense of one horse power will be less in many cases.` But. even 2O inches of water are of no use for such material, for which the machine of the applicant is intended unless one cubic foot of gold bearing matter contains more than 4 cents of gold.

Adoantages.-The following facts will show the advantages resulting from the use of my gold-isolator. It is a known fact that most of the gold deposits are worked over a second and third time and that they pay sometimes better than the first time. The cause of which is that particles of gold have been kept inclosed in pieces of clay, cement etc. and that such have been thrown out by the sluicer or carried off by the current of the water and formed the tailings. The exposure to the air and water isolating the constituent parts of the clay cement etc. prol duces partly or wholly the principal condition for successful gold mining, via: the separation or isolation of the constituent parts of the gold bearing matter. Itis further known that in many cases, where clay, cement or other tenacious earthy matter are predominating, only a small quantity can be worked in'onetday and that such material is exposed to the air, or dried, burned and 'stamped for the purpose of isolating the gold.

By the use of this gold-isolator there is: First, a complete isolation of the gold from all other matterf Second,fno gold deposit Will'have to be worked over a second time. Third, a large quantity of clay cement etc. can be worked, which at present can not be done; either Ybecause the means of reduction are Vtoo expensive like drying, burning, and stamping, or they Veiect only a partial reduction and on a small quantity. A goldisolator erected by the applicant for his private use in Dotys Flat, Placer county, California, is about 7% -feet in diameter and 2 feet wide. Vith less than 10 inches of water and a'vfall of about 10 feet it reduces 1 cubic foot of hard clay in 2 minutes. In the manner of working, as used at present, only about 83 cubic feet jof 'the same Vmaterial could be worked in 10 hours and using 2() inches of water. By using 20 inches of water on the gold-isolator the result would be 600 cubic feet inY 10 hours. Fourth, poor deposits can be worked because a large quantity of gold bearing matter can be reduced. Fifth, whereas the same amount of waterl will reduce a larger quantity,I the charges for it will be less in proportion. Sixth, `there is a large saving of labor, because the goldisolator does all the work of reduction and no deposit will. have to be worked over a second time. Seven-th, gold mining can be carried on in flats and plains, where there is no fall for the water as used at present, and in such high places where a small quantity of water can be got only; because the gold-isolator can be set in motion by some other power and a few inches of water can be pumped. One horse power will eect as much as 100 inches of water costing 10 dollars per day and by using it in the manner it is done at present in the process of sluicing CLESTIN VRINGEL.
