' ALBERTO NOBZEGA, OF NEW YORIL'N. Y.

ORE CLASSIFIER.

Application filed Gctober 4, 192-9. Serial N'o. 414,395.

To all whom it may concern:

Be it known that I. ALBERTO Nom nee. a citizen of the Republic of Peru, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in ()re Classifiers, of which the following is a specification.

This invention relates to ore classifiers and one of the principal objects is to pro duce' a device of this nature which shall be simple of construction. comparatively. inexpensive to manufacture, and cflicientv for the purpose for which it is designed.

Another object is to provide a plurality of co-acting conical members for receiving and directing the differently separate members, a

Another object is to provide an improved agitating means for the conical members.

Anotherv object is to provide a simple adjusting means for said agitating means.

Other objects will appear hereinafter.

All of these objects are accomplished by means described andclaimed hereinafter and fully illustrated in the accompanying drawing comprising two sheets, in which Figure 1 is a vertical sectional view of my improved ore classifier.

Figure 2 is a top plan view of the distributing cone.

Figure 3 is a top plan view of the entire device.

Figure 4- is atop plan view of the col lectlng ring.

Figure 5 is a detail view of the overflow gate.

Figure 6 is a detail view of the adjustable members of the agitating device;

Figure 7 is a detailview of oneof the spring seats Figure 'Sis a detail view of one of the adjustable distributor retainers.

Like characters ofreference parts in alllviews.

This invention contemplates providing an oreclassifier in which the ore crushed and mixed with water is discharged onto a vibratory cone from which it is distributed against the-side walls of; a funnel shaped receiver which is filled with waterhaving an upward current and which washes away the small and lightparticles, the heavier denote like and larger particles rebounding from the sides of the receiver to difi'erent distances are caught by suitable separating means and directed to difi'erent receptacles.

.Referring more particularly to the drawing, 1 represents the framework which is shown as constructed of wooden beams but which may be of any suitable material. and

.construction to support the mechanism hereinafter described. The framework 1 is provided with metal members 2 having collarsor spring seats 3. Mounted in these spring seats are the lower ends of a plurality of spiral springs 4, the upper ends of which are secured to and support an annular member 5 through an opening in the center of which a funnel-shaped receiving member 6 protrudes. The members 5 and 6 are secured togetherin any suitable manner so as to form a trough 7 said trough being inclined toward a spout or delivery element 8. A cover 9 may be hingedly or otherwise secured to the member 5.

. The funnel 6 is provided near its bottom with an outlet 10 controlled by a valve 11, and is provided with an inlet 12 controlled by a valve 13 for permitting the inflow of water from a pipe or hose 14. The funnel 6 is provided at'its top with an aperture or slot in its edge. Adjacent to this slot flanges 15 extend into the funnel from the sides thereof and are connected by pins 16. In the guideways formed by flanges 15 and between the side of the funnel 6 and the pins M3 is inserted a pair of oppositely inclined slides 18 by sliding which toward. or away from each other the level of the water in the funnel is regulated. A glass 19 is set into the side of funnel 6 to permit the operator to view the interior.

Mounted in the base of the funnel 6 is pipe 20 controlled by a valve 21 and having secured to its upper end a collecting funnel or cone 22.

A pipe 28 conducts pulp to a discharge nozzle 24 and is provided with a controlling valve 25. This pipe, passes through an aperture 26 in the cover 9, said aperture being large enough to permit relative movement of members 9 and 24. From nozzle 24 the pulp is discharged onto a conical distributing plate 27 provided with directing ribs '28 which divide the pulp and lead it against various portions of the Wall of the funnel 6. Near the periphery ofcone 27 bolts 29 ass through said cone and also through 5 ots 30 in members 31, said members being rounded at 32 and adapted to be seated against the wall of the funnel 6. By extending these members to a greater or less extent the plate 27 may be adjusted to a higher or lower position in the cone or funnel 6, increasing or reducing the space between the edge of the cone 27 and the wall of the funnel.

An auxiliary pipe 33 is controlled by a valve 34 to permit the use of more water when desired.

Mounted slidably. in bearings 35 in the top 9 and passing freely through sleeves 36 in the distributor 27 are vertical rods 37 which are screw threaded at their upper ends.

and provided with adjusting wheels or handles 38. Secured to the lower ends of rods 37 is a deflector ring or truncated cone 39.

Secured toa shaft 40 which may be rotated by any desired means is a cam wheel 41 provided with a plurality of cams or lugs 42. I

Secured to the outer side of the cone 6 is a member 43 having a lug 44 adapted to be operated upon by the cams 42 to effect vibration of the cone 6 and the devices supported thereby. The inner face of the member 43 is provided with a plurality of serrations45 which are adapted to co-act with teeth 46 011 a wedge member 47 inserted between member 43 and the cone 6. By adjusting the teeth and serrations the wedge 47 will, hold the lug 44 further out and thereby agreater agitation of the devices will be efi'ected by the cams 42.

The cone 22 is adjustable vertically to any desired height in the cone 6 and may be brought low enough to entirely close off the flow of water from pipe 12. Packing 50 forms a tight closure around 20 and screw 51 will hold funnel 22 in any adjusted position.

In operation the pulp is discharged onto distributor plate 27 and moves downwardly thereon into the water in the cone 6. The water circulating upwardly from inlet 12 washes the small and light particles out through the gates 18 into the trough 7 and out through spout 8. The larger and heavier lumps will roll against the sides of cone 6 and rebound therefrom being collected by ring 39 and directed into the receptacle funnel 2.2 from which they may be drawn off through pipe 20 and valve 21. The intermediate particles will follow down the sides of the funnel 6 and may be drawn ofi through outlet 10 and valve 11. The cam device keeps the cone 6 and connected parts in vibration so as to prevent jamming or clogging of the parts. By adjusting the height of the plate 27 and the ring 39, the size of the lumps received by the receptacles may be varied.

It is of course understood that by the use of more cones and deflector rings, a greater variety of grading may be obtained.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any Way departing from the spirit of my invention; and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

What I claim as new and desire to secure by Letters Patent is 1. In a device of the class described the combination of a plurality of concentric receptacles, means for maintaining a fluid level in said receptacles, means for discharging pulp into said receptacle, a conical deflector plate for receiving the discharged pulp and directing it against one of said receptacles to effect variable rebound of the particles, said platebeing arranged with its edge below the fluid level; and means for varying the fluid level for varying the rebound. e

2. In a device of the class described, the combination of a conical receptacle, a second conical receptacle, means for discharging pulp into the first said receptacle, a distributing plate'adapted to receive said pulp from said discharging means and to direct the same toward the wall of the first said receptacle, and a collecting ring adapted to catch certain portions of said pulp and direct the same into the said second conical,

pulp into the first said receptacle, a dis-.

tributing plate adapted to receive said pulp from said discharging means and to direct the same toward the wall of the first said receptacle, a collecting ring adapted to catch certain portions of said pulp and direct the same into the said second conical receptacle, and adjustable supporting means for said ring. V

4. In a device of the class described, the combination of a conical receptacle, a second conical receptacle, means for discharging pulp into the first said receptacle, a distributing plate adapted to receive said pulp from said discharging means and to direct the same toward the wall of the first said receptacle, a collecting ring adapted to catch certain portions of said pulp and direct the same into the said second conical receptacle, adjustable supporting means for said ring.

and means for vibrating the first said re pulp into the first said receptacle, a dis tributing plate adapted to receive said pulp from said discharging means and to direct the same toward the Wall of the first said receptacle, a collecting ring adapted to catch certain portions of said pulp and direct the same into the said second conical receptacle adjustable supporting means for said ring, means for vibrating the first said receptacle, and means for admitting Water near the bottom of the first said receptacle.

6. In a device of the class described, the combination of a conical receptacle, a second conical receptacle, means for discharging pulp into the first said receptacle, a dissignature.
