WASHINGTON BAKER VANDERLIP, or sen DIEGO, cerrronura, assreiven FIVE ONE HUNDREDTHS T0 nn vnsr senses-mow, or new sonar,

To all whom it may concern Be it known that l, lNAsHINe'roN BAKER VANDERLIP, acitizen of the United States,

residing at San Diego, in the countyof San Diego and State of California, havefinvented certain new and useful Improve ments in Ore-Concentrators;and I do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.

My present invention relates to lIl'lpIOYG- merits in concentrators for ores and the like, preferably, though not necessarily, of the .batea or centripetal type wherein a circular vanning movement is imparted to the concentrating table,fand wherein the discharge of the heavy concentrates is accelerated by. a suitable revolving Worm screw, and Wherein this Worm screw may be driven at a vari able speed to conform to the desired rate of delivery of the concentrates; and in vvhich the separation of ,the concentrates from the gangue is accelerated by a series Of radial battle plates mounted in'the bottom of the pan, and whereby also the radius of the circular movement of the pan may be adjusted within limits, so as to impart a variable lateral throw to the pan.

My invention will be more clearly understood after reference to the accompanying drawings, which show the embodiment of the invention, and in Which like parts are indicated by siniilar reference symbols throughout the several views.

1 represents the outer Wall of the p which is attached to and moves with the pan 2, which is in the form of an inverted frus tum of a cone, having the central opening Surrounding the exterior of this conical portion 2 of the pan is a launder a forthe Fig. '3, as seen from the bottom of 5 is an end view as seenfroin the launder f gangue, in-the forin ofa circular trough which is l'JIOLCliflIlClSllflllOW as at 5, and narrow and deep as at- 6, the narrow. and deep portions terminating in outlets 7 which open into any suitable troughs or other conveyers, not shown,for carrying oif the gangue.

Mounted in the interior of the conical portion of the pan are a series .01 radial bafiie plates, preferably of difl'erentlengths and staggered, as shown at 9 and 10. These baille plates are secured ,to the bottom of the pan in any convenient way as by the flanges and bolts shown in Fig. l, and between these flanges, and next to the bottom of the pan,

the baffle plates are cut away to form elongated openings 11, see Fig. 2. Thesebaflle platespreferably all terminate at substantially the Same distance from the outer edge of the cone part of the'pan, but em nenends of the baffle plates 9 project farther toward the opening e than do the short F 2. In this. cylinder is mounted the WOTL'l'Il conveyer 14L, nounted on" the shaft 15 which is gournaled at one end in the botto n .of the cylinder 13, and at the other end in the bearing 17 supported by the bracket 16,

"secured to the inside of thebcttom of the This cylinder 13 .has a delivery opening 13*,through Which theconcentrates fed by 'carriedv by the supports 30. is journaled in "sleeves 31 carried by the the conveyer'le pass. The pan is given a vanning movement, as will be hereinafter described, and to impartrotary motion to the'shaft 15 I provide a broken shaft, consisting vof-the universal joint 18, the shaftsegment 19, splined as at 19 to slide in the sleeve 20, connected by the universal joint 20% to the segment 21, which'segmentcarries the Worm gear 22 meshing with the worm 23 on the shaft 2 which shaft carries the frictiQn. cone 25 Opposite this friction cone, and reversely disposed, is a similar friction cone 26' mounted on the shaft 27 carrying the beveled gear 28 meshing with the beveled gear 52 on the main drive shaft 51., 7

The shaft 27 is mounted inbearings 29 The shaft 24:

stems 32, adjustably mounted in the blocks 34-QBetween the bearings 31 and blocks 34:

other I provide the springs 33, which tend to press "the cone 25 toward the cone 26. These bearings 3d are carried bythe frame35. The stems 32 may be adjusted by means of the adjusting screw bolts 36.

Passing between the two'c'ones is a belt or collar 37, of leather, reinforced rubber, or suitable material, which passes through the shifter 38 and feeding nuts 39 engaging the screw rod 40, having a handle 41. The shifter slides freely on the rod 42,

and may be moved backward or forward along said rodby turning the handle 41. The rod 42 is secured, at its opposite ends to the brackets 43 and 14 carried by the frame 35, and the rod. 46 is journaled in said 7 brackets.

it will be evident that by moving the collar 37 to the right or left between the two friction (zones that the angular velocity of the cone 25, relative to that of the cone 26, may be increased or decreased as desired. In order to throw the cone 25 entirely out of; engagementwhen desired, I provlde a grooved collar 15, fastto the cone 25 and The opposite pair of eccentrics 55 are driven by thebeveled gear 56 carried by the shaft I 27, which beveled gear meshes with the beveled gear 57 on the shaft 51*, at thetwo ends of which shaft are the beveled gears 52 which mesh with the beveled gears 53 and drive the corresponding shaft 5 1 and eccentrics 55. These beveled gears are all arranged so that the various shafts 5 1 and the various eccentrics shall all have the same angular velocity, and in order to get the properdirection of movement of the eccentrics on opposite sides of the pan, the beveled gear 53 should be reversely disposed to the beveled gear 53 The eccentrics 55 may be preferably of the well known type known as adjustable eccentrics, whose eccentricity may be varied within limits, as desired, so that the throw of the eccentrics may be increased or decreased as desired. These eccentrics engage the cylindrical bearings 58 in the housing 59, see Fig. 2. Each eccentric 55 is provided with a stem 60 concentric with the bearing 58, and surrounding this stem are the end friction bearings 61.

Lubricant may be supplied through a suitable lubricator 62.

The housings 59 are rigidly attached to the under frame 63 carrying the pan. The shafts 55 supporting the pan are journaled in hollow columns 61, secured together by suitable tie rods 65.

The ore for treatment is preferably provided to the pan by a feeding device which will evenly distribute the feed of the wet ore to the pan. Such an apparatus is shown in section in Fig. 2, in which represents supporting beams secured to any suitable framework, not shown, which beams support the trough or tank 71, provided with an opening 72 above the cylinder 73, which is supported from the tank 71 beneath which is suspended, as by means of the link 74, a cylindrical metal receptacle 75, beneath which is suspended an inverted cup-shaped receptacle 76, having the flanged annular trough 7 7, which is substantially concentric with the axis of the pan.

7 It will be obvious that if the ore in the usual semi-liquid state be supplied to the tank 71 it will flow through the opening 72 and into the receptacle 75, and overflowing around the sides of this receptacle it will flow into the annular trough 77, and from which it will flow in a substantially uniform sheet into the pan at a suitable distance from the opening 3 therein.

The operation of the device is as fol.- lows Suppose all the parts of the machine to be in operation and the pan to be given the vanning motion imparted to it by the eccentrics 55, the ore in the wet condition as it comes from the stamp mills is fed into the tank 71, flowing down into the receptacle 75, and it flows over the upper sides of said receptacle and into the annular trough 77, whence it is distributed in an even sheet onto the top of the ore already in the pan. The heavier concentrates are gradually shaken to the bottom of the pan under the action of ning said pan, and adjustable .means for i bottom, a substantially vertical cylinder mountedbelowthe opening in said pan and "having a discharge opening, a worm conveyer having close convolutions mounted in i said cylinder, the said cylinder being provided with a discharge'opening below said worm, a fiexlble shaft for rotatlng said wormconveyer, means for vanning said pan, and means-for rotating said flexible shaft. while said pan is in motion, substantially as described.
