Specification of Letters Patent.

Patented Sept. 22, 1908.

Application filed January 22, 1907. Serial No. 353,482.

To all whom it may concern: 1

Be it known that I, ARTHUR. TAYLOR, a subject of-the King of Great Britainand Ireland,

of 71 Edith road, Kensington, in 'the county of London, England, engineer, and whose post-office address is 71 Edith road, Kens1ng ton, London aforesaid have invented new and useful Improvements in Suitable Apparatusfor Concentrating and l/Vashing Minerals,of which the following is a specification.

My invention has for its object to provide suitable apparatus for concentrating and washing minerals, such as finely divided ores, or small coal, whereby any desired rapidity of vibration can be imparted to the gratings,

vorsieves, or to the water in which the mineral is treated, with a minimum expenditure of motive power and with less wear and tear centrating washing apparatus in such manthan heretofore and so that a very efficient concentrating, or washing effect, is obtained even in extremely finely divided minerals. For efficient concentration, or washing, by jigging of finely divided minerals, the lengt l of the pulsations, or strokes, due to the vibration, should lee-reduced to aminimum and the rapidity thereof should be increased to a maximumso as to pulsatory vibrations.

According to my invention I employ a vibrator in combination with the jig, or conner that its pulsations, or vibrations are imparted to the jig, or concentrating, or wash- 111g, ap aratus, or a part, or parts, thereof so as to o tain the required movements, the vibrator being supported on and connected with the jig, or concentrating, or washing apparatus, or with a part thereof by flexible connections, and the said jig, or concentrating, or washing apparatus or the partthereof to which the vibrations'are to be imparted being supported by springs, all as hereinafter more particularly explained.

The vibrator which I employ preferably consists of an eccentric rotatable shaft with journals, whose axes are not coincident with the axis of the shaft. This shaft should be provided with adjustable eccentric weights whose center of gravity can be brought nearer'to, or further from, the center line of the journals. for example, of eccentric wheels, disks, or sleeves, fitted on the shaft so that by moving them round on the shaft, the centers of the Wheels, disks, or sleeves, and the axes of the journals, can be brought nearer to, or furproduce very rapid.

The said weights may consist,

ther from, each other, or the said weights may be otherwiseattached to the shaft so that they can be fixed nearer to, or further from the shaft, keys, or screws, or other suit able means, being provided for fixing the weights in their adjusted positions.

The vibrator may be driven by any suitable mcans, such, for instance, as a belt passing over a pulley keyed to the shaft and made with an eccentric boss so that it can be adjusted andfixcd by keys, screws, or other fastenings, in such a position on the shaft, that it will rotate concentrically, or nearly so, when the shaft journals and weights are all rotating ccccntrically, or the vibrator may be driven by the torsion of a flexible rod, or wire rope, or articulated driver, or by spring gear. The motions of the vibrator are transmitted tlu-rcfrom in the required manner to the part, or parts, to be acted upon by it byflexible connecting rods attached at one end to the journals of the shaft by bearings, and at the other end to the part, or parts, of the jig or concentrating or washing apparatus to be acted on by bolts, screws, keys, or other means of attachment.

. The accompanying drawingsshow examples of how my invention can be carried out in practice, but I do not limit myself to these examples. I

Figure 1 is a side view of the vibrator, partly in section, Fig. 2 is,- an end elevation of the same. Fig. 3 is an end elevation of the vibrator as applied to a ji shown partly in section; Fig. 4 is a side'e evation partly in section at right angles to Fig. 3; Fig. 5 is an end elevation of the vibrator asapplied to a jig of different construction; Fig. 6 is a side elevation of the same, artly in section, at right angles to Fig. 5; Fig. 7 is an end elevation, partly in section, of the vibrator as aplied to a jig of still another construction;

ig. 8 is a side elevation, partly in section, of the same at right angles to Fig. 7; Fig. 9 is an end elevation, partly in section, of the vibrator applied to a jig embodying another modificatlon; and Fig. 10 is a side elevation, partly in section, of the same partly in section at 'ri ht 'an les to Fig. 9. I

Fig. 1 s ows t e vibrator artly in section and partly in elevation, ant Fig. 2 shows it in end elevation. The shaft 1 has, at its ends, journals 2 whose axes (z) are not in line with the axis 'y of the shaft 1. Keyed onto the shaft 1 are sleeves 3 concentric with the wheels, 4 and the shaft ltogether, or be adjusted and fixed in an op osite position, in

which the eccentricity 0 the shaft 1 will compensate that of the disks, or fly-wheels, 4 so that the said disks, or fly-wheels, 4 will be nearly concentric withthe journals 2 of the shaft 1. By adjustment and fixing in intermediate positions', any intermediate eccentricity can be obtained.

The shaft 1 is provided with the pulley 6 A fixed to it and driven for example by a belt from a pulley vertically above it, or in any other "suitable position. The ulley 6 is made with aneccentric boss so t at, by being moved round on the eccentric shaft 1, it

p can be adjusted to," and fixed in the required position by any suitable keys, or bolts, in a position in which it will rotate concentrically-itself, that is, with its axis in a line between the axes of the disks, or fly-wheels, 4 and the axes of the journals 2 of the shaft 1.

The motion 'ofthe vibrator is transmitted by the spring connecting rods 7 to the part of the jig, or concentrating, or washingap aratus to be acted upon, the said rods 7 eing fitted at one end onto the journals 2 and provided'with the bushings 8 kept in position by washers 9 held in place by pins, keys, nuts, or the like. The main parts of the rods 7 are of flexible material, such as thin, well temlpered, spring steel to allow of free lateral viration. said rods 7 are connected to .the part of the jig, or concentrating or washing apparatus to be acted upon, which connection can be done by formin screws on such end, passing these screws t rough attachments to the part to be acted upon and screwing on nuts, or the ends may be slotted to receive cotter pins, or any other suitable means of attachment can be used. The mass constituted by the shaft 1, sleeves 3, disks, or fly-wheels, 4 and pulley v6, will tend to rotate on the center of gravity of the whole mass. If the journals 2 be not in the center of rotation, they will tend to rotate eccentrically and will impart a gyratory motion to the u' per ends of the rods 7, and as the sprin of t e rods 7 allows of free movement laterall only vertical vibrations, or pulsations, will-be transmitted by the lower ends of the rods, and consequently no ower is absorbed in the lateral vibration an the whole of the power, less a minimum of friction, is usefully applied to the part to be acted upon.

Figs. 3 and 4 are sectional elevaticins, at right angles to each other, showing the application of the vibrator to a jig in which a The other, and lower, ends of the .this arrangement the upper grating 10 is fixed in the hutch 11, the proections 12 from which rest between the s rings 13. The sides of the lower part of t e hutch 11 should be thin metal, or other flexible material, to allow of their vibrating, or pulsating. The flexible rods 7 of the v1- brator are connected to the upper art of the hutch by the bridge-pieces 14. he overflow is marked 15 and 16 is the spout for feeding in the material to be treated. The concentrates are drawn off through the valve 17, which is provided with a spiral spring 18 to keep it normally closed by acting on the opening lever. Water is supplied under the grating 10, by the pi e 19 connected to a source of water supp y by a flexible tube. The projection 12 and the springs 13 are shown as being held in position by rods 20 and are carried by beams 21. In this arrangement the whole apparatus vibrates, or pulsates, the flexibility of the sides of the hutch 11 allowing the water to rise and fall through the grating 10 at each vibration, or pulsation. This apparatus is especially adapted for treating the finest slimes. In this arrangement the flexible rods 7 from the vibrator may be applied to any other convenient-part, such as the lower part of the hutch, or to one, or more, of the sides of the,

hutch made especially thin to allow of the requisite vibration.

Figs. 5 and 6 are sectional elevations at right angles to each other showing the a plication of the vibrator to a jig in which tfie grating 10 is fixed in the upper part of the hutch 11, which is divided Into two parts joined by a flexible joint at- 22. The upper part of the hutch 11 may, or may not, be provided with springs at 13, an the lower part ofthe hutch may, or may not, be held by supports. In part of the hutch vibrates, or pulsates, with the grating, and it is especially adapted for the treatment of sand and slimes.

Figs. 7 and 8 illustrate, in sectional elevations at right angles to each other, the application of. the vibrator to the grating 10 of a jig, the said grating being suspended in a fixed hutch 11 The grating 10 is suspended by the projections 12 on springs 13, held in position by rods 20, on the top of the hutch and is rovided with an overflow 15 attached to the utch by a flexible connection to allow of the grating moving and prevent the escape of water, except from above the grating 10. The draw-off valve 17 for the concentrates is shown as being normaly kept closed by a lever and weight 18. In this arrangement the grating 10 only vibrates, or pulsates. The said arrangement is suitable for treating sand and coarse slimes.

Figs. 9 and 10 illustrate, in sectional elevations at right angles to each other, the application of the vibrator to a jig with a plun- (projections 12 resting on gr: 23. The flexible connecting rods 7 are ed to the plunger rods 24, which pass through guides in cross-bars 26fixed across one division of the upper part of the hutch 11 Theplunger is supported by springs 13 as shown. In thisarrangement the plunger moves and communicates pulsations to the water, other division of the upper'part of the hutch 11 and is motionless. his arrangement is especially suitable for treating coarser materials. s L

The parts which are shown in Figs. 5 to 10 corresponding to those shown in Figs. 3 and 4 are marked with thesame reference numerals. I

It will be evident that my inventioncan be analogously ap lied in various ways to suit. various conditions, or requiren'aents.

By the use of a combined vibrator and jig, or concentrating, or washing apparatus as described, minerals in a fine state of di vision, as well as in a-coarser state, can ,be

' shaking, motion to sieves, sortm brought to the highest, or any required,"degree of concentration; It will be seen that the apparatus is of very simple construction,

requiring but a minimum of motive power.

It is subject to a minimum of wear and tear,

and entails a minimum cost of labor in the concentrating, or washing, of minerals.
