NiTED STAES FRANKLIN E. JACKSON AND LUCIUS R. HENLEY, OF GREENTOIVN, INDIANA.

GOLD-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 618,270, dated January 24, 1899.

Application filed April 23, 1898. Serial No- 6'78,589. (N0 model.)

To all whom it may concern:

Be it known that we, FRANKLIN E. JACKSON and LU OIUs R. HENLEY, citizens of the United States, residing at Greentown, in the county of Howard and State of Indiana,have invented new and useful Improvements in Gold-Separators, of which the following is a specification.

Our invention relates to apparatus for separating precious metals from'earth containing the same; .and its object is to provide an improved construction of such apparatus by which we secure important advantages with respect to efficiency in use.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a gold-separating apparatus constructed in accordance with ourinvention. Fig. 2 is a central longitudinal sectional view.

In the said drawings the reference-numeral 1 designates a water-tank provided near its upper end with a spout or pipe 2, having a valve 3 for opening and closing communication between said spout and tank. This spout communicates with a perforated pipe 4, located above or in an inclined sluice-box 5. Connected with this sluice-box, at the lower end thereof, is a vertical pipe 6, provided with a pipe 7 near the lower end, which communicates with said tank and is provided with a valve or stop-cock 8. At the lower end of pipe 6 is a receptacle 9, of glass or other transparent material, which receives the gold separated from the dirt, as hereinafter described. The said pipe 6 intermediate its ends is provided with a curved pipe 10, which communicates with an inclined trough 11, provided with a screen 12 at the inner end, below which is an inclined box 13. Communicating with the lower end of this box is a vertical pipe ll, provided with a curved discharge-pipe 15 and with a pipe 16, extending to and communr eating with the tank and provided with a valve 17. At the lower end of pipe 13 is a transparent receptacle 18, similar to the receptacle 0.

Theoperation is as follows The auriferousbearing dirt and gravel are placed in the sluice-box and water admitted to the perforated pipe from the tank, which, escaping into the sluice-box, dissolves the dirt, forming a plastic mass. This will escape at the lower end of the sluice-box into the vertical pipe 6, when it will meet the water-supply admitted to the pipe 6 from the tank through a pipe 7. This water-supply is so regulated that it will carry the dirt, gravel, and other like debris out through the curved pipe 10, while the gold will fall into the receptacle 9. From said pipe 10 the dirt and gravel and any gold which may be carried over therewith escape into the trough 11 and from thence through the screen to box 13 and pipe 14, where it will meet water supplied from the tank through pipe 17, when the above operation will be repeated, the tailings escaping through pipe 15 and the gold settling in the receptacle 18.

Having thus fully described our invention, what we claim is In a concentrating-machine, the combina tion with the elevated water-tank, the inclined sluice-box, and the perforated pipe located above said sluice-box and extending from end to end thereof and connected with said tank, of the vertical pipe connected with the lower end of said sluice-box having a sight-receptacle at the lower end, and provided intermediate its ends with a pipe leading to said tank, the curved pipe connected with said vertical pipe above the connection of the pipe leading to the tank, the inclined trough having a box connected with its upper end provided with a screen flush with the bottom of the trough and said trough provided with a vertical pipe connected with said tank and having a curved discharge-pipe above said connection and with a sight-receptacle at the lower end, substantially as described.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
