residi gi" at Gary, in the county ot' Lake and State of indiana, both citizens of the United States or' .'liinegrica, have invented a certain new and useful Improvement in Coke-Oven and Charging lvieehaniem, of which the following' is a` specification.

This invention relates to coke ovens and to machinery for charging them. The olojert of the invention is to provide -a coke oven and a charging machine therefor so constructed that the material delivered into 1the oven is inueh more evenly distributed in the oven than has heretobefore been possible, thus doingv away with the large amount of labor heretofore required in spreading the material alter it has been delivered into the oven, and in eleaningE up the coal on top of l' the ovenY after the chargingr operation. A

rfurther olijeet is to so Construct the device that a .inueh larger volume of material may he charged at one time, thus greatly saving the time the oven is out of commission.. and

tl'ieret'ore inereaeing etlieieney. il.' further object of theinvention is to provide an especially arranged and equipped charging machine adapted to he passed over the oven, and to, h v special mechanism. substantially autoinatieally charge the oven without the aid ol root or top Workers adjacent to the eh:ingingr4 opening.

A further object of the invention is to entirely l(lo away With the leveling; machine Whioh in priorl construeiions have had to work through openinp's in the end oi.: the coal rereptaeles ot the oven Vto level oil the material delivered into it.

The vinvention. Consists in mechanism 'For Carrying' out the 'foregoing objects which can he easily and einnparativeljv cheaply made. which is very efficient and satistao,

toi-lv in. operation.v and is not lialile to get out oi. order. lil-ore particularly the invention consists lin many features and details of eonstruction hereafter 'fullg7 set forth in the specilieation and Claims.

s is well understood in the art, a ACoke -to root- 'each ot these compartments `with solid lirici( perforated at intervals. with holes tl'irough which coal is delivered, said Coal falling in conical piles at intervals along' coal Chambers from which condition it had. to be leveled off by mechanism ordinarily operating; through the end of the Coal eliarnf her at considerable trouble and eriense. Furthermore. an operator had to Walk along the top of each coal chamber, sweep into the surplus material left on the top in .the process oi delivering coal into it.r and then put in hy hand circular covers to close the coal Chamber preparatory to the operation of coke making. ln Construction shown in this application. the upper or roof section of the coal chamber is replaced 'o v .i compartment havingn at its cxtreme ends a diagrammatifallv indicated Wall l/l. Fig'. l connected by lonar parallelside lWalls 16 rising' from the top portionlfl of the coal chamber proper g] l l and open continuously into said such coal chamber. This top or supplemental roof passage is of appproximately the dimensions of the coal chamber to 'be `filledv and as the lengths of the side Walls 16 are therefore substantial it is necessary to tie them together. rllhis is done by two classes of intermediate Walls; 20, having through them gas passages 22 and carrying at their tops track rails 24 over which the charging machine passes; and 26 preferably sharpened at their tops in points 28 to assist in breaking up and distributing the coal passing down through the roof box 14--16 into the coal chamber proper.-

It will, of course, be understood that the oven proper consists of a multiplicity of such coal chambers placed sideby side and consequently there are a plurality of these roof passages, one for each coal chamber,y placed side by side as clearly appears in F ig. 2. Adjacent chamber walls are tied together by metallic tie rods 32 which, in the case of the Walls 20 carrying the rails 24,

lie immediately belou7 the rails. as shown in Fig. i. In Fig. 2 the numeral 34 indi- Cates the iiue from the heating chambers (not shown) which areV in the complete furnace or oven, forming no part of this invention, placed between the adjacent coal chambers.

The rectangular top openings left between the ivalls 16 and the Walls 2O are selectively closable by rectangular doors 36 which are in the construction heretofore used about 9 inches Wide and 8 feet long, and are equipped with downwardly beveled edges 38 adapted to insure tight iit when lowered to place as shown in Figs. 5 and 6.

Considering the oven construction thus :tar described, it will be seen that by passing al proper machine over the oven top and dumping coal uniformly along the reotangular openings closed'by these doors 36, a stream ot coal substantially the length of the coal chamber can be delivered into it and that said coal in passing downward said openings to and through the passages 30. will engage the points 28 of the Walls 26 and he broken up and thus fall in as near as possible an even shower into vthe coal pit below, with the result that the resulting pile in the coalchamber will be nearly, it not quite evenly, distributed and require practically no leveling. Even if some manual leveling be required. the openings closed by theI doors 86 are so much larger than the circular holes heretofore provided that such manual leveling is greatly facilitated With consequent saving oi' time and energy.

In order to obtain the advantages of the oven roof construction just described.' a. charging mechanism is provided carried by a car tra vcling along the rails .24, heretoiore referred to, said carbeing of such dimensions that all or the charging openings of a. single coal .chamber may be simultaneously charged with coal. The particular embodivment ot the car shown in the drawings coinprises a rectangular frame 40 ot any suitable constructionY mounted on the wheel 42 traveling from coal compartment to coal compartment ot' the battery or oven over the rails 24.

Supported on this truck frame 4U by any suitable means such, for instance, as the construction 44, 46 is a `coal compartment or chamber 48 extending the length ot the car and `the length of the coal chamber to be charged having at its top intake openings 50 for the reception of coaland at its bottom a plurality of longitudinally arranged discharge ports 52, one for each-of theopenings in the oven top closable by the doors 36.

vThis coal chamber 48 is made of known predetermined coal capacity thereby dispensing with the necessity of Weighing the coal about to be inserted in the coal chamber. In ordinary practice chamber 48 is made ot exactly the right size to take the proper amount oi coal for charging a. given coal chamber of the coke oven. It is therefore necessary only to bring one load to each coal chamber in order to charge the entire coke oven. In charging an oven a train of cars equipped ivith coal chambers 48 may be passed over the oven one car being discharged into each coal chamber or the saine car may be sent back and reloaded and successively used in charging successive coal chambers Without departing from this invention.

Pivoted on suitable brackets 54 on opposite sides of discharge chute or passage 52 are doors 56 or'closing the bottom of the chute and controlling the discharge of coal from coal chamber 48. -The ends of these doors 56 are equipped With end members 58. Fig. 8. provided with slots 60 in which crank pin bolts 62 on the ends of connecting rods 64 are adapted to slide. These connecting rodsare adjustable in length through the threaded links 66 clearly shown in Fig. 8. The opposite ends of these connecting rods are mounted on. 'the end of' a crank arm 68, on a shaft 70. driven by a worm gea-r 72, driven by a Worm 74. on a rod 76, operated by a hand wheel '78. located within the operator`s cage or house 80. The operator can by properly turning this wheel 78 open and close doors 56 for obvious purpose of controlling` the discharge ot coal from chamber 48. Shaft 70, just referred to. also carries the lever arm 82 on whose outer' end is a.. counter weight 84 detachably .adjustable along slot 86., This eounterwei'glit serves the function of normally holding the doors 56 closed witlioit the strain thereof being carried by the gear mechanism 72. 74.

The operatos house or cage 8O also contains car driving' mechanism whichin the :useable particular case here illustrated is merely an electric motor 88 driving one of the Wheels 24 through the sprocket oliain mechanism 90. The controller for the motor 8S is indi cated at 92.

intermediate between the ear frame Ai() and various parts heretofore described7 are stationary beams 94 and S96 at rightl angles to each other. Supported on beams 94 are cross beams 102, one pair ol such beams for each oi the two lifting (cylinders 101. llaeh one oi' these cylinders 104 operates a vertieal piston rod 10G ou'whoselower end is a Cross head meehanism, made up of parallelfbeams 98, 'irojeetingarm 108., and rollers 110 traveling on guides 112 depending from beams 9-1 and connected together at their lower` end by .cross member 111i. Extending parallel with the beams 9S and inside the guides 112 is an angular rod 100, reelproeatively mounted ou brackets 11G7 which are in turn vmounted on 'beam 98.

Rod 14)() is driven bach and for" Ward at the will of the operator by manipre latinoF hand lever 11S piroted on the bottom ot beam 98 at 12A),A there being pin and slot connections 1F32S rod. Between the beams S8 and at points remote 'from the suspension mechanism 10G are blot-ks 12e in Whieh are rotatably mounted Vertical siialits 1536. These Shafts are rotatable through approximately 90 by being" equil'iped.with lever arms ll connected to rod lill) through pin and slot connections 130 eleaily appearinglf in Fig. 1 0. These .shafts 126 are located along the oar one to eaoh end of eaeh door 3b. (in the bottom of each shalt: 126 is an elongated button 182 adapted to be turned by the reoiprcmation ot' the rod 100 between two }iositi iiis,-in one of which it freely passes through the spare or buttonliole 134 between angular liaugre members 13G attached to the door, and in the other of which it is in the position shown in, t3, behind said Hannes and leonsequently eures the door to the adjacent shaft 1% so that 'vertical movement of the shaft Will lift the door. l

rllhis reeiproeation of the shafts and lifting the door obviously' talles place when the operator manipulates the air or other source or' power in cylinders 1041 to lift pistou rods 106 and consequently beams 98. ln the particular construction shown in the drawings cylinders 10i are supplied with air through au air Compressor 140 operated by a motor l14112 controlled by the operator iu his cage through Wires eoutained iu pipe 111. Pipingf 146 is that by which the compressor 140 supplies and operates cylinders 10ft.

general operati/m. i

rllhe operator haring' his ear loaded with coal, in compartment' 48 and the doors 56 elosed as shown in Fig. i2 and with beams 98 drawn up shown iu Fig. 1 but without the between the lever and the doors attached thereto. turns on power to -drive the ear overthe partieular coal ellam- -ber oli the oven which is to be charged with lates the'air in the cylinders 10e to lift all" the doors 36 to the position. shown in Fig. 1. He new moves his car along the track until Chute 54 is over the door openings, extending lengthwise of the eoal receptacle. ,He

nou takes hold of wheel 78. opens the doors 56. whereuliou the' contents ot' chamber 48 slides into the oven opening through the passages 30 heretofore deseribed. and, evenly distributes itsel'l2 along the length of the eoal receptacle. The operator new manipulates handle 7S to elose door 5G, then moves his oar until the doors 36 are ,over their respective entrances to the coal receptacles. whereupon he reverses his operation of oylinder 104, lowers the doors to closed position, and then reverses lever 11S thus releasingI the buttons 132. lele then manipulates cylinders 101 to raise the shafts 1526 to original position 'whereupon he is ready to move his ear on to get another load ot eoal v f As shown in Fig. 1 floors 3d are all in line with each other and are referred to as alined.' Similarly doors 56 extend end to endI across the hopper and are alined.l
