Specification of Letters Patent.

Patented June 4, 1907.

Application filed May 18,1906. Serial No. 317,485.

ore or other pulverulent material and its distribution in regular and even layers in tanks or vats for treatment, and more particularly to the conveying and distribution of metalhferous sands or res in the lixiviationdepartments of cyanid plants, where the tanks are usually circular and arranged in one Or more straight lines, so that they can be filled from cars passing successively over them, or from a belt conveyer arranged along the center line of the tanks and dumping the ore at intervals into them, whence ordinarily it is shoveled from the center toward the sides and leveled by hand labor. These sands have also been distributed by fans, somewhat similar to those used in distributing grain, such being mounted on a traveling bridge spanning the tanks, whence the sand is showered over the tanks, the fans being driven at high speed. The objection to such means, apart from its high initial and Operating cost is that ittends to both size and concentratethe ore, the heavier particles passing toward the pe riphery and the lighter and finer particles falling near the center of the tanks. 'Ihissizing and partial concentration of the ore is quite objectionable in the treatment of high grade ores, and moreover suitable electric power to operate such a distributer is not Often available.

These deficiencies in the art have led to the present improvements, the object of which is to provide a simple and ellicient a paratus, operated mechanically, which shall convey and automatically distribute, over a series of tanksybins or vats, in regular and even layers, well mixed and homogeneous, the pulverulent ores or metalliferous sands with which it is required to fill them. To this end I arrange a single belt conveyer Over the series of tanks, parallel with and adjacentto the central line thereof, usually suspended from the roof timbers, but the ways and track for the conveyer and trip ers may be supported from the tank foun ations, or in any other suitable manner. Belt conveyers and self propelling trippers to dump the ore off the belt at any giyen point within the range consists primarily in the addition to the tripper of automatic means for evenly conveying and distributing from the tripper when located over the center of agiven tank the pulverulent material from the center to the circumference in even non-concentrated layers, said means being preferably actuated by the same power which propels the trippers. Its leading elements are a vertical rotatory shaft operated at slow speed preferably from the belt wheel of the trippers at the bottom of which shaft a short horizontal belt conveyer, which I call the radial distributer, of a radius to suit the size of the tank, rotates with the shaft and at the same time moves from the center outward by its conveying portion to move the ores radially outward to all parts,- suitable means being provided to cause the radial distributer to dump its load in definite proportions as it travels outward, in such relative quantities as to insure an even distribution of the ore throughout the whole area of the tank from center to periphery.

In the drawings forming a part of this specification: Figure 1 shows the movable tripper on its ways supported from the roof timbers, the vertical shaft of the radial (llS tributer mechanism being central over one of the tanks in the line of the series, and the belt distributer extending horizontally from the center to the circumference of the tank. Fig. 2 shows a side View of the movable tripper on its ways, the main conveyer belt by which it is driven, the vertical shaft (the sustaining sleeve being omitted for clearness), and the mechanism of the radial distributer in end View. Fig. 3 shows the mechanism of the radial distributer in enlarged View, the head wheel with the gear connections by which the radial distributer is operated from the main conveyer belt, the chute for conveying the dumped ore to the radial distributer, and the details of the mechanism of said radial distributer. Fig. 4 shows in plan a line of circular tanks with the main conveyer belt located over the same, near the central line, the position of a radial distributer cen- .tral over one of the tanks, and the outer straight rail for supporting the outer end of the radial distributer in shifting from one tank to another. Fig. 5 shows a plan view of the head wheel, the mechanism which conveys motion froni it to the radial distributer, and the means for engaging and disengaging shaft of the radial distributor, driven referi said mechanism. Fig. 6 shows in side view adjustable deflectors which serve to remove the load of ore from the radial distributer belt in measured quantity, with the angular diffusing plates which spread the ore evenly in its fall. Fig. 7 shows the said deflectors in plan view over the radial distributer belt. Fig. 8 is a plan view of the rectangular spider frame secured to foot of rotatory vertical shaft 5, showing the means for supporting the short upright revolving shaft, and for sustaining the pivoted member which carries the radial distributer belt.

1 is the main conveyer belt, driven from a source not herein shown, passing in a sinuous curve around head wheel 2 and bottom wheel 25 of the movable trip er, which latter derives its motion to and fro on its ways in the usual manner from said belt, through ears not shown because forming no part 0 the present invention.

3 is the shaft of head wheel 2, divided into two

sections

3 and 3 by clutch 4, by means of which the two sections are connected and disconnected at will. 5 is the vertical rotatory ably from said head wheel by vsuitab e gear connections, with means to engage and disengage said connections. There must also be a provision to lock said gears in a fixed position when the head wheel is disconnected, as when the tripper-carriage is to be moved from tank to tank. The form of gearing which I have chosen for illustration, and which I prefer on account of its simplicity, is the worm 6 on shaft 3, meshing with worm wheel 7 on vertical shaft 5, which forms an efiicient lock against movement when disconnected, thus precluding the necessity for separate locking means, which however I may employ when other forms of gearing are resorted to.

8 is a thrust collar which supports the weight of the rotatory vertical shaft 5 and connected mechanism on the bottom member 9 of the tripper, said shaft being channeled at 35 to engage corresponding bearings inseparable collar 36, which afiords a seat for the rotatory shaft on thrust collar 8.

10 is a fixed gear wheel bolted to the bottom of the tripper carriage to mesh with a pinion 11 on short upright shaft 37, which is carried around by the vertical. shaft 5 inits revolutions, and is at the same time rotated, imparting motion to .distrib'uter belt 1.2 through bevel gears 13, 14,

sprocket wheels

15, 16, drive chain 17, and driving wheel 18. The upright shaft 37 with its attachmentsis supported. as follows: is a rectangular spider frame firmly secured to the foot of the vertical shaft 5 and rotates withit. To the top of this spider frame is secured the'hopper 23, and to its bottom is secured the hopper 24, both hoppers rotating with the frame and with the vertical shaft. A bracket arm 57 extends outward from this frame carrying a tributer belt 12 sleeve 58 in which the short upright shaft 37 is revolubly supported, with its gear attachments. The member 56 is also pivotally-secured to frame 55 by bolts 20, and carries the inner extremity of the radial distributor or conveyer, the conveyer belt of which is mounted on frame 38, which carries at its extremity the tail pulley 19, preferably mounted in take-up boxes to permit adjustment of the belt tension. There is an extension 29 on the frame 38 (shown in Fig. 1), carrying a wheel or wheels 39 traveling 'on circular rail 40 and straight rail 26 to support the outer end of the radial distributer, and aid it to pass from one tank to another in shifting the position of said distributor. Also to support the outer end of the distributer by its wheeled carriage on the railed edge 40 of the tank, on which it travels as it revolves. Said straight rail is located at the outer edge of the circular tanks in line for the purpose .of sustaining the wheeled carriage 39 as it travels from one tank to another. The member 56 pivoted on frame 55 and rotating with vertical shaft 5 sustains the main weight of the radial distributer and actuating mechanism and transfers it to the tripper carriage and supporting rails 50 by means of thrust collar 8 and separable collar 36. This joint permits the outer end of the distribute'r to seek a free bearing on the circular rail 40 by its wheeled carriage, and thus properly divide the weight between the vertical shaft and the outer rail or rails in spite of any irregularity.

2-1, 22 is a branched chute for delivery of theme from the ma n belt to hopper 23 of the radial distributer. Of said chute the branch 21 is the one ordinarily in use, the branch 22'being only for use in an emergency while the radial distributer is being adjusted- A gate 51 is provided to cut off the branch not in use, and the branch 22 is hinged as at 52 to avoid contact with the framework when in transit:

Beams

30 and 31 suspend from the roof timbers and sustain the weight of the way beams 27 and track rails 50 for the traveling tripper. Saidways and rails are located longitudinally over the line of tanks, so as to bring the vertical shaft of the distributer over the center of each tank in succession.

32 are rollers on member 38 to support dis- 33 are adjustable deflectors provisionally afixed to member 38 to extend over said belt 12 at suitable intervals, in such manner as to deflect over the side of the belt at various points a proportional quantity of ore to insure uniform distribution through: out the tank 34 are adjustable diffusing'plates located on sides of frame 38 to spread the falling ore and contribute to its equal distribution.

28 is one of the tanks of the series, shown in section.

The operation is as follows: The self propelling tripper having been brought over the center of one tank of the series, pulverulent material is fed on to the moving main conveyer belt, and carried over the head wheel of the trip er in the usual manner, but instead'of fal ing in a heap in the center of the tank as heretofore, to be distributed by more or less skilled hand labor, this invention provides for its reception by novel mechanism which insures its equal distribution from the center outward to the periphery of the tank by automatic means. The tripper being placedin fixed position centrally over the tank, as above stated, and the distributer mechanism being thrown into gear, the stream of pulverulent ore enters a hopper. (23) whence it drops through the arms of the spider frame 55 and passes to a deflecting ho per (24) which shoots it onto the distri uter belt in the direction of its travel, which is from the center of the tank outward. On its way suitable means remove from the belt at various points definite proportions of the material to evenly distribute it throughout the area of the tank as the distributer belt slowly rotates, the two simul taneous movements, circular and radial, thus covering every point of the tank surface with its due proportion of material Without the requirement of any thought or skill, in a manner vastly superior to the results of hand labor. I When one tank is properly filled the ore supply is shut ofi from the main belt, the.

distributer mechanism is thrown out of gear, and the tripper is moved by the usual means to the center of the next tank of the series. Before moving, care is taken in each case to set and lock the radial distributer belt frame at right angles to the line of travel, the outer end of said frame being supported by wheel carriage 39 pn the straight rail 26, whereby its transit is facilitated. Having taken its new position the ore supply is turned on, the radial distributer mechanism is thrown into gear, and the filling recommences.

Various means may be employed to re move-the material in graduated quantities from the distributer belt, which readily suggest themselves, but for purposes of illustrationI have shown the adjustable deflectors 33 and the angular diffusing plates 34 as a simple and easily applied means, to which however I do not confine myself. The essential invention lies in the automatic means for radial and equable distribution of pulverulent material in a circular tank of a series, in cooperation with the mechanism which delivers the said material to the trippier and moves the tripper from place to ace. p I claim, and desire to secure by Letters Patent: f
