Referringto' the drawingg a rotary ffaming or rotary; framed structure A comprisesa. fr'amedi structure arranged above a coaltbin or' stacking yard at a suitable longitudinalinclination"or'slope of, for eXample', 2"or,3 degrees: Both: side: walls ofthe framed structure. are formedi'of'steelplates;1*secured'to. ffame members Zor a structure;of"such frame: membersl. Oh the outside of" the: rotary framing or the. framed structure; are, at proper" intervals; attached" supporting, rings 4 having ,re-. spectively; a, peripheral protrusionv 3 and sprocket rings 6' formed respectively with wave-shaped. teeth. or sprockets SaIong the whole or a part of the groom: provided on its periphery}? Each of" the saidsupporting rings rests rotatably, at its bottom, on two grooved rollers 7--7, one for each side, and is held longitudinally in position by a pair of stops 26 provided respectively adjacent the lowest central portion of the supporting ring 4 in such a manner that these stops embrace respectively the said lowest central portion and retain the framed structure A in longitudinal position. Each of said sprocket rings 6 are carried, at its bottom, on two grooved rollers 27, one for each side. An endless chain 10 is respectively passed round the wave-shaped teeth or the sprocket 5 of the sprocket rings 6 and around a small sprocket wheel 9 mounted on the extension of the axle of a driving electric motor 8, whereby said sprocket rings 6 rotate, freely clockwise or counterclockwise. In the circuit of said electric motor 8, are inserted a starting switch 11 and a limit switch 12. The limit switch 12 initiates operation of the motor 8 with the tubs in position in the rotary framing and may be responsive, in known manner, to some physical action such as the operation of the winch 15 hereinafter described. Coal tubs are drawn up on a main rail 13 laid at an inclination of about three degrees in sets, each consisting of several, for example, six tubs. A rope 14 connected at one end to the front end of the foremost tub is secured at the other end round a winch 16, passing over a pulley 15. In the circuit of another electric motor 17 for said winch 16 are inserted an operating button switch 18 and a limit switch 20. The limit switch 20 may also be responsive to winch 15 in known manner. When after connecting the lower end of the rope 14 to the foremost tub (B) on the main rail 13, the winch 16 is operated by closing the hand switch 18, and thereby the set of tubs is pulled up into position on a rail 19 laid at the bottom of the rotatory framing (A), the winch operates automatically by means of the automatic switch 20. At the same time the starting switch 11 is closed to start the driving motor 8, whereby the sprocket wheels 9 are respectively driven to rotate the rotatory framed structure (A) through the chain by, say, 180 degrees, said framing or framed structure being kept in that angular position for a few seconds so that the coal in the tubs can be discharged completely. Therefore, at the moment the framing is caused to returned to its original position by being turned in the opposite direction, the limit switch 20 acts to drive the winch 16 in reverse so that the rope 14 is let out, allowing the empty tubs to descend over the self-acting said switches 21 onto a siding 22. The lower end of the rope 16 is then transferred from the set of empty tubs to the following set of full ones on the main rail 13 and, thus the aforesaid operations may be repeated. Immediately below the central part of the rotary framing (A) is provided a coal bin 23. In front of and behind the bin are arranged a hopper 24 and a conveyor 25 which is below the front as well as rear part of the rotatory framing, so that all the coal discharged from tubs may be gathered in the coal bin 23.

According to this invention, the tubs are hauled up in sets by the winch into the rotary framing rotatably supported with a predetermined inclination, and they are rolled over under pull of the rope so that any securing device for the tubs can be dispensed with, avoiding trouble of setting or engaging the devices. In addition, the present invention has also an advantage in that not only safe and quick operation but wholly automatic handling of the coal tubs is obtained.

Further, according to this invention, an endless chain 10 passes, as described above, around the sprocket 5 or the wave-shaped teeth of the sprocket ring 6, of large diameter, secured to the outside of the rotatory framing A and around the sprocket wheel 9, of small diameter mounted on the axle of the driving electric motor, so that the velocity of revolution of the motor is properly reduced through the smaller sprocket wheel 9 and the rotatory framed structure A can be freely turned either clockwise or counterclockwise. Further, according to this invention, when the rotary framing is stationary, that is, in the normal position, the chain 10 sags, in the lower portion thereof as shown in Fig. 7. In turning of the rotary framing together with the tubs inside, the lower portion of the chain 10 is tightened up so that the chain runs lightly whereby the rotary framing is allowed to turn or return smoothly. Accordingly, the starting of the rotary framing is simple and there is no fear of breaking the chain or overloading the electric motor. When the rotary framing goes around to roll the tubs over, the shock due to the rolling over of the tubs is relieved by tightening of the sagging in the upper portion of the chain. When returning the rotary framing after the tubs therein have been emptied, the electric motor runs lightly at first until the sagging part of the chain or its upper portion tightens up, and the resistance of the framing comes to act on the motor through the chain. Thus, according to the invention, an easy and accurate operation is always effected, insuring smooth starting and returning motion of the rotary framing with no extraordinary load falling on the chain and without any motor trouble arising.

Further, the tippler according to the present invention may be applied to the mineral ores and the like in a same manner as above described.
