(Cl. 209-455) This invention relates to jigs for treating ore so that as many units as desired can be assembled bearing and like materials and is concerned with to form a jig of two, four or more cells and a jigs of the known type which comprise a sieve, common piston rod 20 is provided for operating a chamber situated below the sieve and divided the pistons I5. The rod 20 passes through the 5 by a partition into two hutches, an oscillating bushes l9 and from one unit into another and 5 vibrator situated in an opening in said partition outside the tank I0 through stu?ing glands 2!. for producing pulsion and suction alternately in Each piston is held on the piston rod 20 by means each of the hutches, and means for actuating the of nuts 22 engaging screwthreaded portions of vibrator. the rod. An eccentric 23, with adjustable stroke, 10 One object of this invention is to provide an mounted on a bracket ?xed to one end wall of 10 improved jig of the aforesaid type which is so the tank [0 imparts reciprocatory movements to constructed that wear is reduced to a minimum, the piston rod 20 through a strap 24 and a con and another object is to provide simple and in expensive means for transforming existing jigs necting link 25. The drive for the eccentric, indicated in chain lines in Figure 1, may be by means of belt, chain or other gearing from any 15 convenient prime mover. The top of the tank H] is arranged to provide 15 so as to render them more e?icient. With the foregoing objects in view, the‘inven tion resides in certain novel features of construc tion hereinafter described and claimed. 20 Referring to the drawings:— Figure 1 is a side elevation, partly in section, of one form of jig, Figure 2 is a cross section on the line 2-2 of Figure 1, and Figure 3 is a cross section showing how a 25 standard jig may be converted into a jig accord ing to the present invention. Like reference numerals indicate like parts throughout. Referring ?rst to the construction shown in 30 Figures 1 and 2, the jig comprises a steel tank It] having a pyramidal bottom II. The tank has midway of its length a transverse wall l2 which divides it into two chambers each of which is divided by a partition l3 into two hutches; :35 the four hutches thus formed are indicated by the reference numerals I, II, III and IV. In each partition 13 a circular opening I4 is provided to receive a double-acting piston l5 constituting the vibrator. The piston is held in 40 the opening M by means of a ?exible annulus Hi and clamping rings I1 and 18 of ?at iron. The annulus [6 which is preferably made of rub ber, is shaped so as to allow for lateral displace ment of the piston in both directions. The piston to is preferably as shown in Figure 1 a hollow body formed by two ?at cones of mild steel plate with their rims welded together and a central bush Hi. It will be readily appreciated that such a body, if of suitable dimensions, will ?oat when 50 immersed in water, and can easily be given the correct buoyancy to compensate its own weight, thus relieving the annulus l6 of any undesirable strain. The pistons are coaxially arranged with their 55 axes all at the same height from the base line, an inclined sluice 26 at the bottom of which in each hutch is a grid 27 which supports a sieve 28 held in position by cross bars 29. For treating 20 tin ore, for example, the sieve 28 would receive a bed of hematite 30 of suitable size. Water is supplied to each of the hutches from a main pipe 3| through two branch conduits each controlled by a cook 32 and having at its outlet 25 into the tank ID, a non-return rubber ?ap valve 33. The operation of the jig is as follows. The mixture of ore-bearing sand and water is fed into the upper inlet end of the sluice 26, i. e. 30 into the left hand end of the sluice as seen in Figure l, and at the same time water is admitted into the hutches through the cocks 32. On rotat ing the eccentric 23, the rod 20 imparts a re ciprocatory motion to the pistons 15. When the 35 rod 20 moves towards the left in Figure 1 pulsion will take place in hutches I and III and the water therein will be displaced, will close the flap valves 33 and will rise through the respective ore beds lifting the sand lying thereon. Simultaneously, 40 suction will be produced in the hutches l1 and IV but as the valves 33 therein will then open and admit a certain amount of water, the action of this suction on the sand will be checked to some extent with the result that heavy particles of ore 45 will sink quickly through the sand and hematite bed while sand of lower speci?c gravity will be held in suspension and gradually float away to wards the outlet end of the sluice. The ore which has passed through the hematite bed and the 50 sieve 28 will sink to the bottom of the hutches and can be withdrawn therefrom through dis charge outlets 34. In a jig provided with two or more vibrators, it is not essential that they shall be of the same 55 2 2,070,069 size. They may be of different sizes in order to produce di?erent pulsion and suction e?ects in the different pairs of hutches which is often de sirable. Alternatively, the vibrators may be of the same size and be supported by ?exible mem bers of diiierent depths which will also give dif ferent pulsion and suction effects. Figure 3 is a cross section showing how a known jig may be converted into a jig according _to the present invention. The known jig comprises a hutch the upper part of which is divided by a par tition Ill to provide a sluice 26 and a plunger compartment 48. A plunger 49 is reciprocated vertically in the compartment 48 from an over 15 head eccentric 50. It will be seen that in these The invention is not restricted to the speci?c constructional forms shown on the drawings. 1. In a pulsating jig for treating ore-bearing and like materials, a sieve, a chamber which is closed at the top by the sieve, a transverse parti tion dividing said chamber into two hutches with an opening in said partition, a piston-vibrator which is mounted in said opening so as to produce pulsion and suction alternately in each of said 10 hutches and. which is hollow and buoyant when immersed in Water, and means for reciprocating the piston-vibrator. 2. In a pulsating jig for treating ore-bearing known jigs a plunger, or vibrator, is required for each hutch and that the sieve 29 extends only halfway across the hutch, the other half of which and like materials, a sieve, a chamber the top of 15 which is closed by the sieve, a transverse parti tion dividing said chamber into two hutches with an opening in said partition, a hollow and buoyant is occupied by the plunger compartment 48. By piston-vibrator in said opening for producing 20 dispensing with the plunger 49 and by providing instead thereof the partitions l3 and the plungers l5 of the present invention, the sieve 29 can be extended to the full width of the hutches. Jigs according to the invention may be used 25 in conjunction with launders by building the jigs with the hematite or the like bed on a level with the ?oor of the launders at a suitable position, thus combining these two methods of ore recovery. pulsion and suction alternately in each of said 20 hutches, and an actuating rod for said vibrator, which vibrator comprises two conical discs se cured together in opposed relationship around their peripheral margins and a central bush whereby the piston-vibrator is mounted on said 25 actuating rod.
