,To u/ whom. it may cor/cern:

lie it knou'ntliat i'JfiuiosmoK W. LovsLL, :i citizen of the United States,r residing at tfiei'eiund. in the county of Cuyahoga and finite ot @him have invented a certain new und useful improvement in Coal-lilandiinglfluiuls` oi which the following isa iull, rieur. and erect descriiition.

'tbe'irmfit intention relates 'to a coal liuinlli e plant adapted especially for use ir. ii locality to which. coal-is brought from :i distance, generally in large quantities, l und stored for future use or sale.

The nminobject ot' the present invention is to provide coul storage plant. wherein coni can be stored and later reclaimed much moreeieiiively, with less damage to the foal. and with the expenditure of less time und labor than has been possible heretofore.

finther, the invention aims to provide a :foul handling plant or system ii'xcludingl e' Y inclosure designed to receive sind hold l: quantities of coal and an appeis for grading and delivering ,eroded z coul, together with 'conveying means for transporting the coal to various parts of the incl sure and additional conveying means sporting the coal from an); partof insure to the coal grading and de- .rng apparatus, the Whole beinen so deed und arrnnged that coal can be A,died in s very economical manner, as 'regni-ds length of haulage and espenditure oi t .i und iabor, und withvery little injury to the coal. l

"ne above and other objects ere accomicd by my invention which be summarized as consisting in certain combinations and arrangements of ris which will be described in the speciciiion and set forth in 4the appended ciainis. l

in the drawings wherein have shown one embodiment of my invention., Figure i a ple view of a coal handling plant constructed and arranged in. accordance with the preierred form of my invention; Fig. 2

a partial side elevation 4and a partial seci view through the same; Fig. 3 is a View of a storage .inclosure and screeng; tower, arranged adjacent the storage inclosure; Fig. i is an enlarged side View ci" the screening tower with parts broken away; Fig. is an end view of the saune V.oolting toward the right ci Fig. 4 5 Fig'. 6

isla horizontal sectional view through the screening tower, showinfr in plan the arrangement of several lioppers'for receiving graded coal from the rotar);7 screens of the tower; F ig'. 7 is an end View of the tower looking toward theleft of Fig. 4; and Fig. E# is a side view of e sclf-loading car which is employed in reclaiming the stored coal, and in this case is adapted to convey coal 'from the inclosure to the screening tower.

The coal handling plant constructed in accordance with my invention is, as here shown. arranged upon a dock A, to which coni muy be brought in large quantities by vessels, one of which is indicated at B, The coalis unloaded from the vesselsand stored on the doeii or transported to cars, by means of an unloader C, which, except for one or tivo features, is of well known and standard construction. This unloader includes in this case a bridge C which is supported on towers C? and C3 mounted on Wheels adapted 4to run along tower tracks C4. The unioader also includes a bucket C5 and a trollefv C, both of which may be of the usual construction. Ungra'ded coal .may be loaded directly into cars D adapted to run along ioading tracks D the tracks C* for bridge toWerCt. Between and alone; the tracks for tower C3 areadditional iouding; tracks E aloner Which may be run cera i?. adapted to be 'loaded with coal conveyed by the bucket either :troni the Jessi or from a storage piie on the doelt. Preerebly the tower C3 is provided with screens (not shown), and suitable discharge chutes by means of which the coal' may be screened and the desired grades or sizes loaded into the cars E. A screening tower F is shown alongside the tower C3 and this tower F may be provided with suit-' able screens` and elevating means, b v means of which the screenings or smaller pieces of coal'wliicli passed through the screens of tower C3 may be raised to the top of tower F and again screened.

The major portion of the coal unloaded from the vessels is uhu-ally dumped in one or more huge piles on the dock. This is satisfactory for bituminous` coal, but objectionable for anthracite, and accordingly, 'I prefer to 'provide on the dock a storage inclosure G, adapted especially for anthracite coal and have in'ovidcd effect-ive means for storing the coal. or for introducing the suine into arranged in proximity to ditlierent parts ot the inelosnre, and, in addition, have provided novel and very satist'aetory means for reelaiming the eoal or 'tor withdrawing` it trom any part ot the inelosure. The inelosure G is aranged on the doek between the two innermost loading traeks, and along the line ot travel ot the bridge, so that the latter may pass over the same. rl`he lateral dimensions of' the inelosure. are quite large soas to provide very great eapacity. ln faet, for the uses tor which this partieular plant is designed` the Capacity is in exeess of one-hundred, thousand tons. The heightI of the inelosure is, however, relatively small, so that the bueket supported by thebridge will have sutlieient clearance when. swinging over the saine. ln order that the eoal may be properly introdueed into an inelosnre otl this type, and in order that all parts may be supplied with coal and filled to eapaeityA` it desired. l arrange for introducing the eoal at a large number ot points in the top ot the inelosure. Aeeordingly, I provide in the top a large number of hatehes G', each ot suftieient size to aeeomrnodate and to permit the passage therethrough ot a bueket load. rlhese hatehes are preferably provided with liateh eovers. not here shown` whieh may be arranged tor sliding movement so as to uneover a hatch opening until sntlieient eoal has been admitted tluretlnmigh, and then to close the op,ening. These hatehes` it will be seen, are ar 'auged 'in longitudinal and transverse. rows, and are suftieiently elose together to admit oit the entire inelosure being filled or eharged with eeal evenly and to full capacity.

At. a suitable loeality, preterabl)7 adjacent the ineloslfre is a sereening tower ll. or, as hereinafter referred to, an apparatus tor grading and delivering graded eoai whieh is reclaimed or taken trom the inelosure atter thelatter has been titled or partially tilled in the manner previoi'tsly stated. To eonvey the eoal trom the inelosure to the tower il, I preferably employ a selt loading ear, sueh as shown at-,K in Fig. S. and have provided `tor the ear a traek l wh-ieh extends from the tower along the t'ront ot the inelosure. as indieated in Fig. Vt, and trom the traek K l provide branehes KL whieh extend into various parts ot the inelosnre. ts here shown, two otl these bram-hes extend t'rom the. t'ront ot the inelosure to the rear thereof beneath eaeh longitudinal row ot hatehes. Consequently, when the eoal is dumped into the inelosure` it will tall direetly onto ythe traelt brani-hes KL in a manner suehthat the eoal eau be reelaimed by a self-loading ear. 'lhe ear itselt may be ol any .suitable eonstroetion. but l prefer to provide a ear whieh is propellwl eleetrieall)y and will seoop up a load when moving 't'orwardly along one ot the trai-k branehes K.

After the car is loaded, it is shifted to the tower H, and the load may be dumped in any suitable mannen-in this ease by tilting or inelining the aix so that the load may slide into a pit I adjaeent the lower end ot' an elevator J, forming a part ofthe tower or grading and delivering apparatusvH. In this manner the coal can be removed from all parts of the inelosure.

The self-loading ear K shown in Fig. 8 is pretereably driven by one or more electric motors. and ineludes a body 7n and a door beneath whieh the. motors and gearing for driving the ear and operating other parts are leeated, as shown by dotted lines. At the top of the ear body'is the operatorsl station ZE, in which is located the controller, levers and other operating parts. The torward portion ot the floor ear inelines downwardly as shown, and at the front, the ear body is provided with a eombined seoop and gate whieh is designed to be lowered tothe position shown in the drawing when the ar is being titled. and then to be swung upwardly to prevent the coal from dropping from the torwa rd end when the load is being conveyed to theI screening tower, or other loeality. This gate may be raised by the motor by diseonneeting the latter 'from the driving wheels, and eonneeting it through a train ot gearing to a d rum; which receives a cable the forward end ot which is conneeted to the gate. The ear may be filled by driving it into the storage pile by the developed driving power` but in ease sutlieient power eau not. develop by the motors to effectively till the ear in t is manner, the ears may be toreed into the storage pile so as to receive a load, by 'connecting the motor or motors to a gear arranged'to engage with a slidine rack Z'5 which is carried by the ear and is designed to betempoarily fastened by 'means ot a eateh r at the rear end of the rack. to one of a series ot fixed pins arranged at intervals along eaeh of the traek branches.` To move the ear into the body ot' eoal, so as to cause the ear to reeeive a load, the raek when in its inner position will be attached to one of the abutment pins ZT b v means of the lateh 7e, and `thenee by the gear operating on the raele'the ear will he propelled forwardly relative to the raek whieh is thusv held stationary. The ear is provided at the rear with one or more discharge doors f] through which, the load may bey diseharged. To discharge the eoal, the ear is preferably run upon a tilting platform. (not shown), which is intended to tilt the ear so that the load will'be discharged Lwhen the doors are nnlatelnth'and then :nitoiuatieally ret urn to normal or horizontal position. a

"lhe tover ll'. the eonstruetion of whieh` may be varied eoiisi(lefal ly, inelndes in this instance a suitable 'tritme strueture L, near the top of which ere arranged three set-s of rotary screens N sind @,tne sets M and N being in linewitli eachother and on opposite sides of the center line oi the tower, and the set O being beneath the sets M end N and in the center line ofthe tower. The setsy ci' screens are supported on' rollers et ev sliglit inclination, nnd rnziy lie rotated in any suitable manner and et any desired speed. The-screen M includes an cuter, imperforate cylindrical casing m, and tliree concentric screens m', fm2, and m3,wliicli project outwardly beyond the casing difieren# amounts, tire innermost screen 'projecting from the casing tlie greatest distance, in a similar manner', the set N includes e cylindrical casing n, and three concentric screens. nf, ai? and nii, which are arranged in e manner similar to that of the screens andi casing of the set M. The innermost screens of both sets M and N receive coal from the elevator J, which, et its upper end, is prei vided with a discliargecliute J" having two spouts J2, each of which is designed to direct coal into one oi the screens. Beneath tlie outer 'projecting ends of' the several screens and screen ensings are lioppers receivers R", R2, R3, and lf3-the first ci which receives `the larg-est size of ccnl, namely, so-called egg cool; the second, stove coal; the third, nut coal; and the fourth receives from the imperforate cesings m and it, the dust and smaller pieces which are passed through three screens of escli set. .Traded coal passes from the receivers E', R2, R3, through discharge spouts into lion pers S, ,""2, und Si end the coal which passes into the receiver liti discharged ley means of e suitable spout into the innermost screen of the lower set 0,- Whicli consists of nn imperorete outer casing; o eine two con centric screens o and o Jliicli project ont wurdly from the casing' o different distances, :is sli-own clearly in Figf.' The coal 'which enters the inner screen 02 is then again screened and graded,-pea coul, intel-:Wheat coal and dust passing into the receivers T, T2 und T, und tlien into lloppers Si, und S, the hoppers S to S being, arranged in the manner shown in Figs. 4, 5 end 6. These' various lioppers are provided near the center piene ef the tower with discharge spouts ST, the passage of coal through each of which muy ce controlled manually so ibut the desire-i gilt-ide or sir/.e of coal een lie obtained any time. These spouts are edspted to discharge tlie coul ents one or incre substantially horizontal endless conve-yers U having e discharge chute V by which the coal can be disclirged into cnrs W or other suitable coul receiving members.

W'hilc I prefer to .einplny the Ainclosure 'for tlic stored coul, under some circmnn stances, ill, inclosure may be dene zii-.sw
