ing equipment which 'is -well known to those y l shlled 1n 'the art and needs `no detailed' explanation.. In accordancewith the usual i practice after the overburdenfhasv been removed a snglerailway track 10 is laid on the coal .to be du l0 is Venriployedv poses in general the use of a portable coal at T which may he self propelled or whic may loe-moved. about'in any suitable manner on the track l0, and in conjunction with the tipple B up. .Only the single track` or the reason that it .must4 he shifted about to permit the mining ot all the coal. The present invention-pro tov a number of railway cars, designated/at l1, l2, 13 and 14 being the ordinary' cars,

used for tipping or transporting the coal to the point of use or storage. The portable coal tipple T maynot only be moved Aabout 'en the tracklOduringthe mining o eration in an particular locality but may item one locality to another,A

a so be moved vthereby avoiding the very serious `lossreas well as eliminating intermediate haul the coal 1s aimed-tc.

Sltationary tipple, '1110i inai'ter more fully described.

The portable coal tipple T which constitutes the present invention comprises a Wheeled platform 16 which may take the form of an ordinary railway car and which runs on the track 10. On one end of the platform 16 a power plant 17 is arranged and may utilize a steam boiler and an engine to drive the generator employed for generating the electricity utilized to drive the various instrumentalities of the tipple or an internal combustion engine may be employed for this purpose. lt is also to be understood that the Wheeled platform 16 may be self propelled by means of suitable electric motors or other means or Adjacent the power plant 17 the Wheeled platform 16 is provided with ahopper 18 into which the coal is dumped asmined from the steam shovel S. An elevator 19 is .cmployed to carry the coal from the hopper 18 to the upper of a series of classifying screens, designated generally at 20, and hererEhe elevator 19 is rotatably supported in a conventional manner on a frame 21, the

frame 21 being secured at its lower end to the wheeled platform 16 and being connect-q ed at its upper end to a pair lof masts 22. It is to be understood of course that the elevator 19 is ofconventional construction and is electrically driven in accordance with the usual practice.

'lhe shaker screens 2() constitute the means for classifying or grading the coal, and in the embodiment illustrated three shaker screens are-v employed and are arranged one above the other, there being a top screen, designated generally at 23 for separating the block coal from the egg, nut and slack, a middle screen 24 for separating the egg from the nut and slack, and a bottoln screen 25 for separating 'the nut from the slack.

As shown .in Figure 5 the shaker screen 23 includes a frame havingl tracks 26. -The screening element consists of a metallic plate 27 having perforations 28 admitting of the passage of all sizes of coal except the block size. This screening element 27 is mounted for reciprocatory movelnent on the tracks 26 by means of rollers 29 carried by axles 30- provided on the plate 27. The track 26 may consi-st of angle irons as shown although channel irons', might be lemployed to fatford a/more positive drive if found desirable.

Means is employed for imparting reciprocatory movement to the plate 27 and may comprise an electric motor 31 with which gearing 32 is associated which drives a wheel 33 fixed to a shaft 34 rotatably mounted in bearings 35 and extending transversel below the upperl end ofthe screen 23. disk 36 is also/fixed to the shaft 34 and the wheel 33 and isk 36 carries crank pins 37 which are operatively engaged with connecting rods 38, thelatter being also pivotally connected to arms 39 fixed to and extending laterally from the screening element or plate 27. Y

The screening elements of the shaker screens) 24 and 25 are similarly mounted and reciprocated.

At its lower end the screening element 27` is formed with an imperforate extension 40 providing a chute for delivering the block coal onto a loading conveyor designated generally at 41 and mounted for longitudinal moven'ient or adjustment o-n a boom desig' i nated generally at 42. may be hauled or drawn about as desired.A

'lhc boom 42 is made of structural steel and is of rectangular tubular form. As shown in Figure 2, the boom is supported on one end of the Wheeled platform 16 by means of a. bearing-plate 43 suitably fixed to theplatform 16 and serving as a mounting for a rotatable plate 44 pivotally con-` nectedby means of a pin 45 to the plate 43. The plat-e 44 is secured to the boom 42. An electric motor 46 drives the plate by means of Worm gearing 47. With this arrangement the boom 42 is mounted for swinging movement inl a horizontal plane so that slight curvature in the track 10 may be taken care of. ln addition to the supporting means thus provided for the boom 42 a. plurality of guy lines 5() extend between the masts 22 vand various points along the boom. These guy lines 50 may be separate elements or they may be composed of a single cable trained over pulleys 52 carried by each mast and pulleys 53 mounted on the boom and then Wound on a drum V54 controlled from a motor 55 by means of gearing 56.- Of course such a cable 50 is provided on each side of the boom, there being one cable for each mast 22, and there being a set of pulleys and 53 for each cable.

The conveyor 41 is shown to advantage 1n Figures 6 and 7 and comprises a mam frame 57 and a pivoted section 58. The main frame 57 includes fixed side bars 59 and the pivoted section 58 includes pivoted side bars 60, and these side bars 59 and 60 carry rollers 61 and 62 around which the endless conveyor element 63 runs. As shown to advantage in Figure 6 the pivoted bars 60 are arranged at one end of the Fixed bars 594 and areS pivotally connected to these fixed bars. The inclinanationof the bars 60 with respect to the bars 59 is controlled by means of'a cablev '65 having one end connected to the pivoted sections 58 and having its other end wound about the Winding drum 56 controlled by an electric motor 67 4mountedon the main of an electric motor 68 and gearing 69 between the electric 'motor 68 and the end frame 67 ofthe conveyor, th'wheels 71l run# roller'O overI which the conveyorv element is trained.

`With this arrangement the coal' is taken as it is mined and at the place where it is mined and is graded or classilied and the classilied products are immediately loaded into individual cars ready for shipment to the point of use or storage, In this manner the vintermediate haul of the coal as mined from the point at Which it is mined to the stationary plant at which it is graded is eliminated.- Moreover the coal is directly loaded after the grading in such a novel and efficient manner as to occasion a. minimum of handling and so as to permit of continuous operation. These advantages are had and at the Vsame time a portabletipple from place to place 'during the mining operation and from one locality to another.
