ORE-CONCENIL-RATOR.

Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed December 2, 1904. Serial No. 235,269.

To all whom it may concern:

Be it known that I, VVILLiAM ORSBORNE J OURNEAY, a citizen of the United States, and a resident of San Antonio, in the county of Bexar and State of Texas, have invented an Improved Ore-Concentrator, of which the following is a specification.

My invention is an improved machine for separating valuable portions of ores from the gangue. The construction, arrangement, combination, and operation of parts are hereinafter described, the features ofnovelty being specifically indicated in the claims.

In the accompanying drawings, Figure 1 is a longitudinal section of the machine. Fig. 2 is a side elevation of the machine without the outside or supporting frame. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4 is a horizontal section on the line 4 4 of Fig. 2. Fig. 5 is a horizontal section on the line 5 5 of Fig. 2. Fig. 6 is a horizontal section on the line 6 6 of Fig. 2. Fig. 7 is in part a plan view and in part a horizontal section of the cut-off valve applied to the lower portion of the machine.

The working parts of the machine are supported in a suitable rigid iron or wooden frame 1. The pulp or material composed of mixed ores and gangue is received from rolls or stamps into a flaring hopper 2, whose .lower portion is constructed as a cylinder, and

from which it passes into the main receiver 4. The same is constructed with a cylindrical body and conical lower portion, its lower terminal being a receiver for the concentrates, the same having a form similar to the receiver 4. The latter is supported by brackets 5, attached to the 'main frame 1. The hopper, with its cylinder 3, is attached to the hollow shaft 6 by means of horizontal bars or arms 7. (See Fig. 1.) The bars 7 have flanged or outturned ends, which are bolted to the respective parts in a suitable manner. The shaft 6 is arranged in suitable bearings 8 and 9, supported upon the upper portion of the frame 1 and provided with supports 10, formed of Babbitt metal or some other metal which will have but slight friction. In place of such hearing I may employ antifrictionrollers. Rotation is imparted to the hollow shaft 6 by means of bevel-gearing 11, operated by a horizontal shaft 12, having a bandpulley or other propelling device 13. It will be seen that the shaft 6 extends down nearly to the bottom of the lower or concentrate receiver 4 and that guides 14'are arranged at the lower end of the cone of receiver 4, through which the shaft passes and in which it is free to rotate.

To the cylindrical body 30f the pulp receiver or hopper I attach curved arms 15, (see Fig. 3,) which are extended horizontally and to which a series of vertical bars or plates 16 are secured, as shown. Owing to the conical form of thelower portion of the main receiver 4, the lower portions of the plates 16 converge in a similar way. It is apparent that the main receiver 4 is stationary, while the hopper, with its cylinder 3 and the attached stirrer 15 16, is revolved by means ofthe shaft 12 and the miter-gearing 11. By this means the pulp is stirred or agitated in the main receiver, the heavier particles being forced toward the center and descending, while the lighter portions, such as sand, are forced upward and pass off through the opening 17 in the upper portion of the receiver 4 and are thus discharged into aflaring hopper 18, that surrounds such portion of receiver 4. The upper edge of this hopper is turned outward and downward and overhangs a circular trough 19, which is inclined from one side to the other of the main receiver4 and provided at its lowest point with a discharge-spout 20. Below the opening 17 in receiver 4 are other similar openings 17. Such portions of the material as may be forced upward and pass outward through the openings 17 and have suflicient weight will pass down in the hopper 18 and again enter the receiver 4 through the lower openings 17 while the lighter portions or tailings proper will pass off over the top of the hopper 18 and into the surrounding trough 19. In order to facilitate the separation of the heavy and light materials, I provide a water-inlet pipe 21, which,

as shownin Figs. 1 and 4, connects with an annular jacket 22, forming a space surrounding the conical lower portion of the receiver 4. Such portion of the receiver has a series of tangential slots 23, through which waterhas access to the interior. A valve 24 is provided in the pipe 21 for controlling admission of water at this point. Within the concentrate chamber or receiver 4", forming the lower end of the main receiver 4, I arrange a small agitator'or stirrer 15 16*, which is a counterpart of the stirrer and agitator in receiver 4, save in respect to size. It is attached to the hollow shaft 6, and thus revolves with it in the same manner as the larger agitator.

A shaft 25 extends down through the, hollow shaft6 and is connected with a horizontal plunger 26, arranged in the lower portion of the hopper-cylinder 3. This plunger consists of radial arms which extend laterally through slots in the hollow shaft 6. (See Fig. 4.) To the upper portion of the shaft 25 are applied two disks 27 28, which are spaced apart and between which a cam 29 is arranged torevolve. (See Figs. 1 and 2.)

other propelling medium 31.

It is apparent that the rotation of the cam 29 will impart an up-and-down or reciprocating movement to the shaft 25, and therebyto the plunger 26, which will in turn impart a pulsation to the pulp in the main receiver 4, which, as experience has demonstrated, materially facilitates the separation of the concentrates from the other material. It will be seen that this pulsating operation goes on simultaneously withthe rotation of the receiver and agitators in the receiver 4 and concentrate-chamber 4, the plunger 26 necessarily revolving with the shaft 6 and its connected parts. i

At any time when it may be desiredthe main receiver 4 may be cut off from the concentrate-chamber 4 by means of a valve composed of two horizontal wings 32, (see Fig. 7,) which are pivoted at a common point 33 and adapted to swing horizontally to open or close. The said wings or valves are operated by means of links or pivoted arms 34, which are connected with a nut 35, and a rotary cylindrical screw 36, that passes through said bar and is provided with ahandle 37. The operation is obvious. The function of this valve 1 is ordinarily called into play when the chamallow discharge of the concentrates therein. 1

, This valve may be constructed in various ways;

but, as shown in Fig. 5, it may consist of a horizontal triangular plate pivoted at 40 and provided with a handle 41 for operating it and with an opening 42, that may be brought into or out of registration with the dischargenozzle 43 of the concentrate-chamber.

A water-chamber 44 (see Figs. 1, 6) surrounds the cylindrical portion of the concentrate-chamber 4, and slits are provided in the adjacent portion of the chamber in the same manner as illustrated in Fig. 4'in relation to the main pulp-receiver 4. The said slots are narrowand tangential, as shown, so that water is admitted in thin or sheet-like currents that are directed around the inner side or wall of the receiver.

Water is admitted to the chamber 44 by The cam is fixed on a' horizontal shaft 30, having a band-pulley or.

means of a pipe 45, provided with a stop-cock 46. The water thus admitted serves to wash the concentrates, as will be readily understood. The general operation of the appa: ratus may be briefly recapitulated, as follows:

The pulp delivered from stamps or rolls into the hopper 2 passes through the cylin drical portion 3 thereof and into the main receiver 4. The agitator 15 16 therein revolves ,with the hopper at a rate of, say, thirty to sixty revolutions per minute, the speed being determined mainly by the material being: The revolving wings 15 16 not only treated. agitate the pulp, the same passing to some extent between the parallel strips 16, but the material is thrown outward by centrifugal action, and by the effect of gravity theheavier particles pass gradually to the bottom of the:

of pulp in the receiver 4 and the lower chamber 4.

centrates, and then, the lower valve 39 being opened, the concentrates are discharged. Wa-

ter may be turned on through pipe 45 and water-jacket 44 to clean the concentrates and also to make the machine work more easily, I

since the series of tangential water-currents admitted from the surrounding chamber flow in the usual direction of rotation of the agitator; but the latter may be reversed if it be desired to create greater agitation of the concentrates and to wash them more thoroughly. 1

Water forced through the pipe 21 into the receiver 44 obviously renders the pulp thin ner, and thus facilitates the rotation of the agitator 15 16, so that the worthless and light material is more easily carried upward and caused to flow out of the receiver into the surrounding hopper 18. finally accumulate in the top portion of such hopper pass over-the curved edge of the same into the delivery-trough 19.

It will be understood that ordinarilythat is to say, when the machine is not worked too fast and not flushed with too much waterlittle or no valuable material will pass downward in the outside hopper 18. Thus the machine operates continuously and concentrates the valuable portion of the ore rapidly and perfectly. The machine can be worked with greater activity when the material is sized before introduction into the same.

The tailings which '95 When it is observed through the glass window 38 that the chamber 4 is filled with concentrates, the valve 32 is closed to prevent sands, &c., from mixing with the con- A pipe 47, provided with a stop-cock 48, (see Fig. 1,) is connected with the lower end of the conical pulp-receiver L for use in discharging the liquid or finer portion of the pulp when required.
