GOLD-SAVING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 419,908, dated anuary 21, 1890. Application filed .Tune 19, 1889. Serial No. 314.862. (No model.)
To all whom it may concern:
Be it known that I, OLIN I-I. BAGLEY, of Knappa, Olatsop county, State of Oregon, have invented an Improvement in Gold-Saving Apparatus; and I hereby declare the following to be a full, clear, and eXact description of the same.
My invention relates to the class of apparatus or machines especially adapted for saving tine gold from black sand; and my invention consists in the hereinafter-described novel construction of separating-table and the peculiar riffles thereon.
The object of my invention is to provide a simple and effective machine for saving gold from black sand.
Referring tothe accompanying drawings for a more complete explanation of my invention, Figure 1 is a vertical longitudinal section of my apparatus. Fig. 2 is a plan. Figs. 3 and 4. are modified forms of riftles.
The frame A of the table is made up of side and end pieces properly joined. The bottom or working surface of the table is made of a plate B at the head, the surface of which is grooved, as shown, and successive plates C, each of which carries or has formed with it a riiiie l). All these plates are secured in grooves a of the side pieces of frame A, rubber strips a being placed in the grooves to form tight joints, the whole series of plates being held in place by a single key E, driven in between the lowermost plate and the end bar of the frame A.
The riiiies D, carried by plates C, have inwardly-beveled recessed or concaved faces, and each end is provided or formed with eX- tension flanges or Wings CZ, whichv project toward the head of the table and upwardly along the sides of the frame.
To better understand the invention as far as described, I will at this point set forth its operation. The whole table is int-ended to be suspended at an inclination from or mounted upon hangers or standards and mechanism connected with it, so as to impart to it a side shake and a bump, buffers a2 being provided on its sides. This hanging and motion I have not deemed it necessary herein to show, as many machines of this and kindred classes are so arranged and operated, and for the sake of clearness I have omitted these devices, as they form no part of my present invention. The gold-bear ing sand and sufficient water are fed upon the head of the table, and, passing first over the grooved plate B, the current is broken and sufficiently retarded thereby to prevent the stuff from rushing too fast over the rst riftle of the series. Then meeting said riftle, a separation of the gold from the sand takes place, the gold being caught by the beveled or recessed face ofthe riflie, and, spreading out to each end thereof, leaves the sand and water about the center of the rifile, over which it flows and repeats the action on Vthe next riftie. At the ends of each rifle the flanges or wings d prevent the water from splashing sand or gold .over the ends and keep the sand and Water nearer the center.
The recessed faces of the riiiies may be curved in the direction of the length of the riffle, or they may be straight. The rifties may be formed, as shown in Fig. 3, of a single metal plate bent upwardly at one end and curved out to form the recessed face and the end lianges integral, or they may be formed, as shown in Fig. 4, of a single metal strip curved and of a semi-cylindrical shape, but in every case presenting the recessed face to the downward flow of the sand and Water.
The riftles are cleaned or partially cleaned with a fiat shovel and brush; but when a general cleaning is desired one side of frame A is detached7 so that all the plates, being released, may be taken out and cleaned.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patenta isa l. In a gold-saving apparatus, a riiiie for the table having a recessed face formed by turning the material at one side of the riffle back upon itself, said ril-lie having projecting end nanges or wings, substantially as de scribed.
2. In a gold-saving apparatus, a riiitle -ior the table-surface having the material thereof at one side turned back upon itself to form a recessed face curved in the direction of its length and opposing the now of material on the table, substantially as described.
3. In a goldsaving apparatus, a riiie for IOO the table-surface having the material at one side turned back upon itself to forni a recessed face that is opposed to the flow of material on the table, said rifiie being` curved lengthwise and provided With forward1y-pro jecting iiangcs or Wings at its ends, substantially as described.
4. In a gold-saving apparatus, the combination of the frame A, the grooved plate B 1o at the head of the frame, and the plates C,
.forming the bottom thereof, and the recessed In witness whereof I have hereunto set my I5 hand.
