mains closed, rising and falling with the trap except when the trap is below a predetermined depth.
When the trap sinks below this predetermined depth it sinks away from the lower edge of the gate leaving an opening for discharge of slate.
Experience has shown that if the slate conveyer 16 is in operation during the higher positions of the trap there may be some coal carried into the trap along with the slate, and to prevent this loss of coal the slate conveyer is only in operation when the trap is in its low position.
The movable slate trap is supported as explained in my inventions previously referred to by links to variable moment counterweighted levers which take care of the additional weight due to the accumulation of slate by an effective increase of arm when the trap sinks, the arrangement being one in which the trap will sink by reason of greater weight from accumulating slate to an extent that is exactly balanced by the greater moment of the counterweighted levers.
As explained in my patents above referred to, material oscillation of the trap with the oscillation of the water is prevented by means of a suitable damper 18.
The electrical switch 19 controls the operation of the slate conveyer and when this switch is open the slate conveyer does not operate.
This switch is open whenever the trap is in the relatively higher positions and as the trap sinks into a relativelylow position a projecting arm 20 on a fixed part of the supporting links 21, engages a pin 22 on a lever 23, resulting in closing switch 19, which starts the slate conveyer, either by starting a motor 25 as shown in Figures 1 and 2, there being another motor 26 for operation of the coal conveyer or by closing a magnetic clutch 27 (Figures 3 and 4), on the shaft 28 of the slate conveyer and a corresponding shaft 29 co-axial with 28 operated by chain drive 30 from the motor of the coal conveyer, see Figure 4.
Closing the switch 19 by reason of the low position of the trap thus results in starting a motor 25 that is special to the slate conveyer or in closing a magnetic clutch 27 between the shaft of the slate conveyer and another shaft having continuous operation from the motor of the coal conveyer.
Figure 5 shows a modification whereby the result of having the slate conveyer only operate when there is an ample depth of slate in the jigger box is accomplished differently.
A. jigging ball 31 with an arm 32 pivoted at 33 is made of such relative weight and volume that it occupies a position between the coal and slate in the jigger box, on top of the slate and beneath the coal, with the result that it rises and falls with the depth of slate in the jigger box, and the outer end of the arm 32 is made to engage the pin 22 of the switch operating lever 23 thereby controlling as in Figure 1 the operation of the slate conveyer, the arrangement as before being one in which a sufficient depth of slate re sults in closing a circuit that starts the slate conveyer to continuous operation until the depth of slate becomes insufficient when the circuit opens and the conveyer stops.
In operation there is a relatively small rise and fall of the slate trap 13.
As the slate accumulates above the trap, the trap is depressed by reason of the greater weight upon it and in it until the gate 15 begins to open and finally until the switch 19 is closed either by an arm 20 on some part of the supporting linkage or by means of the jigging float 31. I
The greater portion of the slate within the trap is now discharged through the gate 15 and the resultant lightening of the weight upon the trap causes it to rise which stops the slate conveyer by opening the switch 19 and closes the gate 15 by coming into contact at the projecting lip 41 with the lower edge of 15.
The area of admission into the trap 13 increases as the trap rises and the trap gradually becomes charged with slate with the re sult that as slate further accumulates above it, the trap again sinks and the whole operation is repeated.
It is desirable to be able to temporarily lock the trap 13, as for example preparatory to slushing the jigger box.
This is accomplished by means of a rod 3 L attached to the bottom of the trap 13, passing through a stuffing box 35 and carried by a lever 36 hung by a link 37 to a fixture 38 on the bottom of the jigger box.
The lever 36 with pin hole 4 .2 slides along a holed plate 39 and is set in any position with respect to 39 by means of a pin adapted to fix the lever at any desired position on 39.
The handle of this lever is conveniently placed along side of the handle of the slush gate 40 so thatan operator, preparatory to slushing the jigger box, is enabled to lock the trap 13 into this higher position by mov- 5 ing the lever 36 upward and fixing it in place with a pin.
It will be evident that the weight does not increase above the movable section as rapidly as the weight of the slate in the movable section is reduced by discharge of the slate, both because there is not the same depth of addition within the same time and because the addition is not wholly slate.
I am aware that-in view of my invention and disclosure modifications and variations of my invention to meet individual whim or particular need may become evident to others skilled in the art and I claim all such variations and modifications in so far as they fall within the reasonable spirit and scope of my invention.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In apparatus for separating slate and coal, a jigger box, a Slate trap in the jigger box, means for automatic variation of the vertical position of the trap with the depth of slate in the jigger box, a slate conveyor and an automatic control between the vertical position of the trap and the operation of the conveyer.
2. In apparatus for separating slate and coal, a jigger box, a slate trap in the jigger box, means for automatic variation of the vertical position of the trap with the depth of slate in the jigger box comprising supporting linkage connected to the trap and a variable moment counterweight support con nected to the linkage, a slate conveyer and an automatic control between the vertical position of the trap and the operation of the conveyer.
3. In an apparatus for separating coal and slate, a jigger box, a slate trap in the jigg'er box, means for automatic variation of the vertical position of the trap with the depth of slate in the jigger box, a slate conveyer and an automatic control between the switch in the circuit and mechanical linkage controlling the switch and operated by the trap.
4. In an apparatus for separating coal and slate, a jigger box, a slate trap in the jigger box, means for automatic variation of the vertical position of the trap with the depth of slate in the jigger box, a slate conveyer and an automatic control between the vertical position of the trap and the operation of the conveyer comprising a motor for the conveyer, an electric circuit controlling the drive of the conveyer by the motor, aswitch in the circuit and mechanical linkage operated by the trap and controlling the switch, the motor being a magnetic clutch between a moving shaft and a shaft of the conveyer.
