' Application tiled March 25, 1887. Serial No. 232,422. (No model.)
To all whom it may concern.-
Be it known that we, ORIN CAMPBELL and WILLIAM PEET,'citizens of the United States, residing at Lawrence, in the county of Douglas and State ofKansas, have invented a new and useful Improvement in Ore-Concentrators, of which the following is aspecification.
Our invention relates toimprovements in I ore-concentrators,and is designed more espe' chute.
cially to separate particles of gold or other heavy or precious metals from the sand and earth with which gold,-parlicularly, is associated in surface-diggings or mines.
The invention consistsin the construction and arrangement of the chutes down which the mixed metal and sand or earth descend,and of the mechanism for. actuating said chutes, as hereinafter described, embraced in the appended claims, and illustrated in the accompanying drawings, in which Figure 1 represents a perspective view of an ore-concentrator embodying our invention. Fig. 2 represents a vertical section of the same on the line x x of Fig. 3. Fig. 3 represents a plan view of the machine, showing the upper Fig. 4 represents a plan view of the lower shoe. Fig; 5 represents a front end view of the machine. Fig. 6 is a detailed transverse sectional view of the shoe D.
Referring to thedrawings by letter, A designates the frame of the machine, of general rectangular shape, and composed of the horizontal top and bottom beams, a and a, respectively, and the vertical end and side beams connecting the same.
B is the hopper secured to the front upper end of the frame, and provided on its front side with the door I), having its side edges beveled so as to fit into and be retained by the corre-. spondingly-beveled edges of the side'pieces The door may be held open atany point, so
as to enlarge or diminish the feed-opening b, by means of the adj listing-screw b which passes through a threaded opening in the door and impinges on the board b below. I
C is the highest chute, hung from the top beams, a, of the main frame by the metal spring-straps O O,pivoted at their upper ends to the beams a and at their lower ends upon the side strips, 0, of the chute. The chute G has a floor,;c, consisting of metal plate, to preplate-metal shoe, D, fits.
its lower end.
which have their upper and-lower ends'revent wear and tear, the side parts ofwh ich" floor are bent up againstthe side strips, 0, and
then bent down and secured to the edges of 5 said strips.
The chute is open or has no strip at its lower end, so that there is free discharge of refuse therefrom. The lower part of the door of the chute is cut away, forming a'rectangular opening, a, over which a detachable similar to the metal floorof the chute, and has its side portions similarly turned up against I the side strips, 0, and again bent outwardly to rest upon theupper edges of said strips. The shoe is provided with the V-shaped riffles d,,which run transversely across it and I The said shoe'i's I have their upper ends joined togetheror to 'the sides of the chute, so that nothingcan pass down the latter and escape the'riffles.
d d are openings through the floor of the shoe, just within the points of the riffles, and t I of proper size to allowgrainsof metal to es- 7 cape through them. v
E is a chute inclinedin the opposite direcimmediately below the hopper. The upper end of'the chute E is secured to the lower or discharge end of the chute O, and its lower end is closed with a transverse strip, e. The floor e of thechute E is similar to that of, the chute O, and is cut awayjat its lower end to make a discharge-opening, e, just above the stripe.
F F are vertical spring-straps similar to the straps O, and have their Iupper -and lower ends pivoted, respectively, upon the side strips ofthe upper chute and of the chute E near G is a chute similar to its higher end secured to the lower end of the chute E, inclining downward, thence to the front end of the machine, and suspended from I I tion-tothe chute O, the upper endof which is 1 the chute C, having 0 the chute E by the vertical spring-strapsg,
part of the floor of the chute G. Theshoe H; to:
is provided with closed V-shaped riffles h,
similar to but having larger angles than the riftles d, as there'is less refuse to separate in the chute G. I.
h If are openings through the shoe within the points of the riffles h. (See Fig. 4.) The lower end of the shoe G is open for the discharge of refuse.
I is a short spout or ('hute below the opening h, having its sides secured to the side strips, 9, and inclined downward forwardly to discharge into the drawer 2', which slides in the transverse ways i, secured to the lower beams, a, of the main frame.
The following is the actuating mechanism of the chutes.
J is a transverse shaft journaled in bearings secured to the vertical beams of the main frame, below the hopper, and carrying a pinion,j, outside of one bearing and an eccentric (ram-disk, j, centrally between its bearings. The said cam-disk rests and fits in a notch, k, in a block, K, secured to a transverse beam under the upper end of the floor of the chute G.
L is a transverse shaft turning in bearings secured to the vertical beams of the main frame below the shaft J, and having secured upon it a gear-wheel, l, which meshes with the pinion One of the extended ends of the shaft L is squared to receive a crank handle, Z, by which the said shaft is rotated by hand, and the other end has secured upon it a pulley, Z by means of which and a proper belt the machine may be actuated by an engine. The material is fed into the hopper dry, from which it is permitted to descend in proper quantities to the chute (3, which, together with the connected lower chutes, receives a longitudinal vibration from the mechanism caused by the rotation of the cam-disk in the notch. This vibration slides the material down the chute C and causes the particles of metal-such as goldto sink, through gravity, to the bottom of the moving mass; hence the said particles are caught by the riffles d and directed through the openings (1, while the bulk of the sand, earth, and other refuse passes over the riffles and out of thelower end of the chute.
From the chute O the particles of metal mixed with less refuse pass down the chute E,
which is merely a transferring-chute, into the chute G, down which the material passes and is still further concentrated by the rifiles h. The particles then pass through the openings 7L2, and, mixed with much less refuse, flow down the chute or spout I into the receiving-drawer 1'. Other chutes with similar rifiles maybe added, the material receiving one degree more of concentration from each.
By the described construction is formed a simple, compact, and effective machine for concentrating ore by the dry method.
Having thus described our invention, we claim 1. The combination of the hopper and the actuating mechanism with the communicating chutes provided with platemetal bottoms having the V-shaped closed rifiies and the openings within the points or angles of said riflies, each chute having riflles made on a wider angle than theone above, so as to decrease the numberofriiiies and floor-openings from above downward, substantially as described.
2. The combination of the main frame having the hopper, the shaft L, gear-wheell on said shaft, and the shaft J, carrying the pinionj and the cam-disk j, with the chute 0, provided with the metal floor c, the plate D, having the riffles d and the openings (1, the blocks K, having a notch, 70, to engage the cam-disk, the straps O,supporting said chute, the chute E, secured to and inclining'in a different direction from the chute G,the chute G, parallel to the chute O, and provided with the plate H, having the riffles h and openings h, and the spout or chute I, secured to chute G below chute H, substantially as described.
' In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
