To all whom 'it may concern:

Be it known that I, Oni: J'oiixsox, residing in tiilwaiikee, in the county of Milwaukee and State of lllisconsin, have invented new andA iisefiil Improvements in Aipara- Dis* i charging Material, of whichthe following is a description, reference being had to the accompanyiiig` drawings, which are a part of this specitication. v A

My intention has relation to improvements iii apparatus for elevating, transport ing, and discharging material.

'lliepriniarr object of the invention is to provide .a' construction wherein the power -mediiiin for causingthe travel ofthe carringe, for raising and lowering the bucket,

and i' or opening and closing the bucket jaws is earriedsdirectly on and travels with the carriage. vinstead of being stationary and independent of the carriage, as has heretosfere been the practice in this class of devices.

further object resides in employing, in connection with a construction of the above character, a in'eans for balancing the weightot the bucket.

Vith the above primary, and other incidental, objects in view, the invention consists of the devices and parts, or the equivalents thereof, as hereinafter more fully set forth. l

to travel on the rails of the track.

of the invention will now be' referred to,viz.',' y

the arrangement of the power, mediuiiifo'r' driving the carriage, for raising' and lowering tliebiicket, and for opening and closing: the Jaws of the bucket, thesaid power inediiiin being carried directly by the carriage,

and being under the control of an operator" on thecarriage.

The numerals 20, 21 and-:22 indicate,re'

spectively, three motors which are nioiintcd directly on the carriagef The motor-9.0, at

the rear of the "carriage, is for the purpose et' d riviiig the carriage` or, in other words,

causing the travel of said carriage, and to this end the motor shaft is geared up to thel axle of the rear wheels of the carriage, so that when said motor is started, the rotation' of the motor shaft will cause the rotation of the axle. and hence the carriage will oe nioved either forwardly or rearwardly,inv

accordance with the direction of turning of the motor shaft. The two remaining ino-w:

tors Q1 and 22 are respectively for the purpose of operating the ropcsfor opening and closing the bucket jaws and for raising and Y lowering the bucket. the operation of which will be hereinafter fully pointed out.

I employ in connection with my invention, Va clam-shell bucket. the two main members `of which consist of segmental jaws 23--23 'genial sie thejws numeral 29. This rope is meeting. Just below the ae `pivotally connected to a pivot shaftQ by means of arms 25.- The amis cross each other in diagonal planes, and at their upper extremities, .above the pivot shaft, carry 'sheaves 26-26. f Links 27 are connected to the outer ends of the upper of the pivoted bottom segments or andeonverge upwardly to a point of pointo convergenceot the links 27 is carried a sheave 28.

he rope or cable for opening and closing of the bucket is indicated bj' the connected at one end to the front end vof the carriage, thence iscarried forwardly around a guide sheave jaws,

-' 30 at the frontl end of the booni l0, thence guide sheave 32,

rearwardly and beneath a guide sheave 3l, thence at a slight upward inclination over a thence continued rearwardly at a sheave ,Blteonnected to the top of a counter-weight 35, thence upwardly and over a A of rope, 'indicated wound therearound a plurality .of times, and

' and thence upwardly and connected at its continued downwardly to slieave 28. Extensionrope 38, after leaving sheave 28, is continued around ione of the sheaves 26, -thence upwardly and over sheave 28, thence downwardly and around the other sheave 26,

end toa stud 39..

The-lifting or elevating rope is indicated by the numeral 40, and the lower end of this rope is connected to an eye 4l at the point of convergence of the two links 27. :This -rope is'continued to and wound around and secured to another drum 42 carriedthe carriage. The motor E21 controls the. winding of drum 37, that is to say, the shaft of this motor is geared up to the drain shaft, so f that when the motor is set in its shaft rotated, the drum shaft 'will be ro operation and tated in a direction to either raise or lower the rope 38, in accordance with the direction of rotation of the motor shaft. Drum 42 is controlled 'by motor 9,2 in the same manner,

.that is to say, the motor shaft is geared up to' the drum shaft, soas to rotate Vthe drum in a direction either to raise or lower the rope 40, in accordance with the direction of turning of the motor shaft. The several motors 20, 21 and 22 are all under the control ort an operator traveling with the carslight decline, and over a guide slieave 33 at the rear end of the frame S, thence downwardly and around a 38. The

venieiitly located with respect -right shafts 55-55.

'the different motors,- provide trolley poles l5-'15 carrying trolley wheels 4G. These wheels 46 are adapted-to engag electrical conductors artrolley rails 47447 extending longitudinally along the main frame 8, ex

tensions 48, thereof, also extending lougi tudinally along the boom. The current passes from one of the trlley rails, down the trolleypole'to the controlling levers ell, and

by suitable manipulation of these levers bv .the operator any one orinore of the inotoiis may be thrown into the circuit, and the inotors thus operated. The. other trolley pole and rail form thereturn for the electrical current.

If desired,'the entire apparatus-suny be inade portable, in order that it may be conto a vessel from which coal is to be taken, or with respect to piles of coal at dilerent locations.,

This is accomplished byproviding wheels 49 at the lower ends of the lower portions 16 of the side supports 17, and similar wheels at the lower end of the legs l2 of the rear support. These wheels, it desired, may run on suitable rails 50. Mechanical means are advantageously employed for causing the entire apparatus to travel along the rails, and Ato this end I provide the side frames 17 with a motor 5l, the shaft 52 thereof being geared to :nid adapted to rotate upright shafts 55 through the internieshing of the gears 53453, Qn* the ends of shaft with gears 54:54 .Tori the upper ends of said up- The lower ends of these upright shafts are geared to the axles of the w eels 49 so vas to cause the rotation oic said a les. A motor 56 is mounted on the learn( sporting frame, and the motor shaft 110 57 d i an upright shaft 58 through the niediflli of suitable gearing,` and this upright 58, in turn, drives ,the axles of the V wheels 49 of this rear supporting frame through the medium of the gearing between the lower end of shaft 5S. and the axles of wheels 49.

The inveited U-shaped low`er portions 16 of the side frames 17 are suiliciently high to permit of the passage of cars beneath the top member thereof. These cars are shown by dotted lines in Fig. 1, and the two outer cars are indicated by the numerals 59, 59, and the intermediate smaller car by the numeral 60.. It' desired, after the bucket is loaded,and raised, the carriage 18 can be moved to a position along its track so as to dump its load into a hopper 61. This hopper has leading therefrom a passage (l2, and the bottom of passage 62 'formed by an finalised Screen es.' The mi which is de; posited in the hopper 61 passes into the pas-Y sage 62, and the large lumps .of co'al' pass down-the inclined screen,'and through dis'- charge spouts- GAQ-GiUu-ihich diyerge outwardly in directions 'to discharge into the "cars :S9-Q59.v The'ifiner particles of coal ,p'a'ss through theineslies of the sieve, and enter, a

spout 65,. whichfis'in pjsitionfto'discharge.

vthese tine particles intol the car 60.

For the sake of describing the operation Y of the apparatus, it will be assumed that the bucket shown in Fim 1 had been first low Vered into the vessel 66, with the jaws of the bucket intheir open position. The motor 21, under the operation of the apparatus would then be thrown into operation, and this would y'cause a winding o' cable 38 and a closing ofthe jaws'of the bucket e The motor 22 is next put into operation, and both motors "will then he effective' in winding up I cables 38 and 40, and consequently hoisting tion, in accordance the loaded bucketiip to the carriage. Motor 20A is now set into operation, and this will cause the carriage totravel in either direc- 'itli the direction of turning of the motor shaft, and the carriage will then travel to av place where it is desired toduinp lthe load. When this place is reached, rope 40 is held, the niotor 21 reversed, and the shaftthereof thereby caused to rotatein a direction to unwind rope 38.

- This will cause au opening of the bucket jaw-'sand a dumping of the contents of the bucket, and if itis desired to first lower before dumping, motor 22 is reversed, which will ,cause an unwinding of rope 40, and when thebuckct is lowered sulliciently motor 2-2`can be thrown out of operation and inotor 21 put into operation in a ina-nner toopen the jaws as hereinbefore described. After .the bucket has discharged its contents. the motor 20 may again be set in action in such manner as to cause the carriage to travel along the ti'ack to the point of loading.

It will be seen that by the arrange-.nent of the ropes in connection with'l the counterweight 35 the weight oi' heft ot the empty bucket is always countei'balanccd. :While provision has heretofore been nia de for counterbalancing the weight ot the empty buckets in this class of devices,- Vet l aiu not aware that a counterbalancingmeans has been provided in connection with av carriage in which the power uiediiuu for operating the carriage tion, however,l is, the provision:broadly-of the power inediuni `carried by the-carriage;

ordinarf'arr: iig veineuts,'A where :theA power mediuinis located at a point' distantfromdistance from tliepositionof the operator being' frequently .very great. :ln "fact, under Athe/,old construction it is frequently neces- Saly' 'folan exti'a'-nian 'tobestationed at -the point of dumping tosignalthe operatorat Ltlie-fpoint .,wliere" .the power...inediuni -is con-1 trolled,A so that said operator inay know when to drop the bucket. Under my present improvement, wherein the operator tra-vels with the load, and is at a point above the load, he is always in a )osition to -riew the entire operation of loa ing and unloading, and can thereby iuost advantageously control the saine. My improved construction, also, renders it necessary 'only tofemploy minimum amount of'rope, owing to the fact that the winding druins are carried directly on the carriage. Y

Y In Fig. 7 o'dbe drawing I show a slightly modified mrope connection wherein instead of the rope 38, after leaving the lastl sheave 2G beine' connected terminali to a stud 28, is continued up into the groove ofsheave 28, ata point opposite to its first vcontact with said sheaveand extended to and connected with a pin or stud 6T r0- jecting laterally from the; carriage 18. his Fig. 7 construction of bucket is similar to the construction of bucket covered in Letters .Patent issued jointly to the present ap li-v cant and John Johnson under Patent Jo. 716.5239, dated Dec. 16, 1909., and should be provided with the locking means fully described in said Letters Patent, the locking means referred to providing for locking the bucketin a. closed position, and alsolocking the saine in an open position. i

Referring more in detail t the operation of the bucket, it is to be statet` that by winding upon the rope 38, the upper ends of the arms 25 are brought together, and the jaws of the bucket ai'e consequently also brought together and closed. On the other hand, by unwinding or slackening rope 3S, and holding rope 40 tautl` the bucket jaws will open by gravity.
