PATENT OFFICE.
OF NEW YORK, N. l'.
IMPROVED APPARATUS FOR CONCENTRATING AURIFEROUS ORES.
Specification forming part of Letters Patent No. 42,06 5, dated'Mareh 29, 1864 5 antedated March 21, 1E64.
To all whom it may concern Beit known that I, JosErl-r A. BERTULA, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Means forv Ooncentrating Auriferous Ores and Sands;
' tudinal section ot' my concentrating apparatus.
llnclineol planes with cross slats or rifles have heretofore been employed for concentrating metallic ores or sands washed over such inclined trough by water supplied at the upper end.
My said invention applies to this general character of concentrating apparatus; and it consists in a movable grating or gratings, whith rest upon the inclined planel or trough and form grooves or ritles for the concentration of the auriferous sands or ores, and when raised allow such concentrated materials to be washed to the lower end ot' the incline or into any suitable receptacle, thus avoiding the trouble and delay experienced in cleaning out the grooves separately, as has' heretofore been done, and I make the grating deeper atv the lower end of each section than-at the upper end, so as to form a deeper groove or receptacle for the metallic ores and sands, and thereby retain in such rilies the heaviest particles in the shallow grooves, while the less valuable portions are deposited in the deeper graoves.
In the drawing, a is a screen or sieve, upon Which the metallic ores or sands are placed, and the sufficiently line .portions washed through such screen by a stream of water supplied at the pipe b, or otherwise, while those particles that are two large are conveyed away for regrinding. The metallic ores or sand and water run away upon the inclined plane or trough c, that is made .of any suitable material and placed at the required inclination.
d is a grating, which I prefer to be made ot' metal, ot a width to till the trough, and of any suitable length, so that one, two, ormorev terials lodge as conveyed along by the stream l of water, and these bars or slats are deepest at the lower end, or are gradually deeper from the upper to the lower end of said grating, as shown, in order that the lighter metallic particles may be deposited in the deeper grooves formed between said slats,where the current of water will not act so powerfully as ih the shallowcr grooves. When the grooves become sucientl y f ull,the metallic ores or sands are cleaned out of them by allowing the water to flow while the grating or gratings are raised,- and the concentrated materials may be removed frein the lower end of the incline or pass into any suitable receptacle. Pins may be introduced through the sides ot the trough to hold up the gratings While they are being washed out and the concentrated ores delivered. By this means the delay and costot' removing the concentrated material from the grooves or rides is very much lessened.
What I claim, and desire to secure by Let. ters Patent, isl 1. 'lhc movable grating or gratings d, applied to the inclined plane or trough of oreconcen trating apparatus, for the purposes and substantially as specified.
2. The bars or slats 1 l, found deeper at the lower end ot' the grating than at the upper end, for the purposes and as specified.
In witness whereofI have hereunto set my signature this 31st day of August, 1863.
