JIGGING-MACHINE FOR DRESSING ORES.
Specification of Letters Patent.
Patented July 26, 1910.
Application filed August 31, 1904. Serial No. 222,896.
To all whom it may concern:
Be it known that I, HENRY RICHARD HANCOCK, mining engineer, a subject of the King of Great Britain, residing at Burnside, in the State of South Australia, in the Commonwealth of Australia, have invented certain new and useful Improvements in J igging-Machines for Dressing Ores, of which the following is a specification.
This invention relates to jigging machines, and the object of the invention is'to provide an apparatus of this character which is effective in operation and which secures certain novel results, all as hereinafter more particularly pointed out.
In the drawings accompanying and forming a part of this specification I illustrate an organization involving my invention, which I will set forth in detail in the following description, but I do not limit myself to the showing thus made, for material variations may be adopted within the scope of my claims succeeding said description.
The foregoing advantages, as well as others possessed by the machine represented in the drawings, will be fully disclosed in the said description and in said drawings Figure 1 is a side view partly in section of the hutch and jigging apparatus showin my improvements. Fig. 2 is a sectional end view of the hutch and sieve showing tailings discharge, rubbers, and water pressure apparatus. Fig. 3 is a part plan of the hutch and sieve showing the rubbers between the sides thereof. Figs. 4c and 5 are detail side view and plan respectively of my improved tailings discharge. Fig. 6 is a detail view of the steel shoe as attached to the cam lever. Figs. 7 8, and 9 are detail sectional views of the sleeves or protectors on the lever shaft.
A is the hutch mounted on suitable supports and divided into any suitable number of compartments A by means of movable divisions A provided with india-rubber or other flaps A Within the hutch A the sieve B is suspended to which is imparted an alternate rise and fall simultaneously with a forward and backward motion by means of the cam C. The, ore is fed on to the sieve at B and the tailings carried over the discharge end B into the tailings compartment D.
The tailings compartment D is provided with an improved apparatus for automatically discharging the tailings at the end of the hutch A without undue loss of water. The apparatus consists of two or more valves E of iron or brass preferably conical in shape which fit into seatings E in the bottom of the hutch A. The seatings may be of iron or'where the water is deleterious of wood and be readily renewed when worn from use. Each valve E is connected to a vertical rod E provided with a lever F at its upper end. The levers F are keyed to shafts F extending across the top of the hutch A and may be arranged in pairs as shown in Figs. 4 and 5 by being connected or coupled at their upper ends by means of plates F".
A driving shaft G is provided across the hutch A on which are mounted two cams G set at different angles. The shaft G is preferably revolved at about fourteen revolutions a minute and the cams G as they revolve engage reels F attached to the plates F thereby lifting the vertical rods E and opening the valves E alternately by means of the levers F.- On the, cams G disengaging the reels F the vertical rods E are re leased and the valves E by their own weight fall into their seatings E. Care must be taken that the rods E and valves E combined are of suflicient weight to insure their effectively closing the seatings when released from the cams G. An automatic discharge of the tailings is thereby effected Without undue loss of water from the hutch A and from the cams G being mounted at different angles on the shaft G the valves E are opened and closed alternately. If a large quantity of tailings is to be produced two pairs of valves E may be in operation at one time (as shown in Figs. 4 and 5 of the drawings). With a smaller quantity of tailings a lesser number of valves may be employed while when treating very rich ore producing a still smaller quantity of tailings the apparatus can be thrown out of gear by turning the belt on to a loose pulley.
The hutch A at the discharge end B of the sieve B is divided byvmeans of a slanting partition H so fixed in the end of the hutch A that its upper end is about two inches from the end B of the sieve B. Any slimes which may escape on to the sieve B from the slime washers are carried by the flow of water over the end of the sieve B and the partition H and settling obliquely are caught by the partition H and run out through the outlet H at the bottom in the end of the hutch A. The tailings discharging from the end B of the sieve B drop ver tically underneath the slanting partition H into the tailings compartment D from whence they are withdrawn through the valve openings E.
In order to more effectively maintain the sieve B in position and prevent the water from rising except through the sieve B I interpose rubbers of hardwood or other suitable material and india-rubber between the sides of the hutch A and of the sieve B in segments for the Whole length thereof. The hard wood is attached by means of a plate J and bolts J 2 to the hutch and in use projects against the india-rubber R suitably attached to the sides of the sieve B.
For the purpose of treating heavy ores and insuring the heavy particles of ore stuff being carried over the sieve I introduce water under regulated pressure to the sieve B with every pulsation thereof through the openings K provided with india-rubber flap valves K The water is supplied from an overhead cistern fitted say twelve feet or more above the level of the sieve according to the nature and density of the material under treatment kept full of water and connected by means of a pipe or launder K with the flap valves. Taps J are provided in the pipes K to regulate the supply. In practice the introduction of this Water under regulated pressurehas been found of the greatest importance in improving the efficiency of the jig and preventing the tendency of the water to form a vacuum at the rising of the sieve as it also prevents the light waste on the top of the sieve from being drawn into the concentrates by suction at the rising of the sieve. The flow of water upward through the sieve under regulated pressure further serves to kee the waste stuff in a state of buoyancy an to cause it to be carried over with the tailings at the discharge end of the sieve.
In order to preserve and protect the longitudinal lever L which is actuated by the cam C from which motion is imparted to the entire machine the end of the longitudinal lever so attached by the cam is provided with a cast steel shoe L which may be fitted to it by a bolt L and when worn out be readily renewable.
To economize the wear and tear on the longitudinal lever shafts M at each end of the hutch sleeves or protectors M of iron or steel are attached to the shaft M. These sleeves or protectors h are fitted into 'brasses M and are held in position by collars N at each end of the plumber block N. The collars N are fastened by means of set screws N The sleeves or protectors M take the wear and tear off the cam lever shaft M and preserve the said shaft M from the waste water and other deleterious water flowing from the valves 0 of the hutch A and may be readily renewed.
Upon the shafts M are fixed crank arms 5, to the inner ends of which are jointed rods, each designated by 6, the rods rising from the respective crank arms, and being connected at their upper ends to the crossrods 7 located above and near the opposite ends of the sieve. The sieve is flexibly suspended from these cross-rods 7 Connected to one of the cross-rods in any desirable way are radius links, as 8, said links being jointed to some relatively stationary part of the apparatus.
The foregoing is a brief description of a way of securing a vibratory motion of the sieve in the manner hereinbefore set forth.
It will be understood that the levers L are linked together, to secure their motion in unison. A power shaft, as 9, is represented as situated below the inner ends of the two levers L and as provided with a substan tially triangular cam, as 10. The shaft 9 may be operated in any desirable way. Upon its rotation the cam 10 will engage the shoe L to impart, through the intervening mechanism just set forth, an up and down and endwise reciprocatory motion to the sieve. I
\Vhat I claim as my invention, and desire to secure by Letters Patent, is
1. In an apparatus of the class described, a hutch, a sieve mounted in the hutch for endwise and vertical reciprocatory motion, the hutch having outlets at the delivery end of the sieve, a valve for each outlet, and automatic means for opening the valves at inter vals and in alternation. I
