Fig. is an end view of the apparatus, looking substantially from the line '55 of Fig. 1.

The cage 1' is in the form of a cylindrical drum positioned horizontally to rotate about its longitudinal axis above a hopper, themouth of-which is indicated at 2. The cage 1 is built up ofmetal plates and angle sec- III) tions so as toform a substantially closed drum, except for a central longitudinal passage 3*therethrough which receives the car to be dumped, and an'upper spill-opening l,

throughwhich the contents of the. car is;

dumped when the cage is inverted so'mewhat less than the lowerhalf of the drumjis divided into three separated compartments 9, 10,'and 11, by the transverseend partitions 5 and 6, and the intermediate partitions 7 and 8. Supported by the transverse angles 12 at r the tops of theseveral partitions5, 6, 7 and 8, 2e

are longitudinally extending angle beams 13 which carry the rails 14:, which extend from end toend of the cage parallel with its axisof rotation", that is from the end partition 5 tothe end partition 6; Extending up from I the transverse partitions at either side of the car-receiving passage 3, are parallel vert1cal closed by arcuate plates. Thesmaller upper part of the drum from wall. 17 to wall18 at the top is opened'to provide the spill opening 4, and at the ends of thecage, beyond the ends of the opening l, the circumferential sur face of the drum is completed, as indicated at 19 and 20, by means of arcuate plates and suitable strengthening members." Complete annular shields 21. and 22 (hereinafter described more in detail) extend outwardly beyond the respective ends of the cage proper, substantially as continuatio-ns of the outer cylindricalcasing of the cage. Openings 23 (seeFig; 2) are formedin the outer casing of theldrum, leading to the compartments 9, 10

Annular drivlng racks-25 are also secured toithe cage adjacent its ends,.as -here shown the racks 25 be V brackets 28. In former dumpers ofthis type,-

ing mounted on flanges 26 at. the outer sides of thesupporting rails 24.- .The rails 2 1 rest on--supporting rollers-27 carried by suitable it-has'been tliought'necessary to set the supporting trunnio-ns'forthese'rollers on radial lines at; approximately 45 with the-verticalfully v adjustment.

on eachside of the axis of the druinor cage. I have'discovered that substantially halfof. this angle is suflicient to .providestabllity and the result is-that instead of a trunnion load of 1.4114 times the weight of the car andf la ding, I-havea trunnion load'of only 1.08, which decreases proportionately the power required to revolve the dumper. In order to prevent apossible tilting of the dumper on its supports, which might"throw thedrivinggears (hereinafter described) out of mesh, a pair of idler rollers. 29 are provided which engage the supporting rails 24- adja-' racks 25 on the cage. A pinion 36 secured on shaft 31 drives a gear 37 onthe shaft 38 of an automatic controller 39 which governs the driving motor33. The'gear ratio is such that shaft 38 of the controller will make oneicom plete revolution for each revolution of the cage 1, so that the controller will always rotate in complete synchronism with thecage. The controller 39 is of the type embodying a plurality of rotating cams and" cooperating con tact members whereby, after the first ele'etrical contact has been'made', the contacts in the controller will "automatically accelerate the cage rapidly to its maximum speed, then decelerate' it to a very low speed and finally cut off the power just before the cage completes its revolution and drifts into thelatch mechanism, hereinafter described. Automatic electric controllers of-this type arewell known,l and it hasnot been deemed necessary to describe or show same in detail. However, devices of this k1nd haveformerly been devised which depend on'contacts made by points on the cage itself. These devices are defective, in

that the apparatus is subject to inj ury by conit cannot be entirely protected. According to the present invention, the driving mechanism isgeared positively to the cage through spur gearing and the controller is also geared j to a secondarycounter shaft in such manner that it will always rotate in complete synchronism with the cage. InIthis manner the controller may be so positioned that it will be protected, and readily accessible for Mounted adjacent eachend of the cage is a vertical standard 40 (see Figs. 1, 2 and 5), in

which isslidable a carriage 41, positioned betweentwoheavy compression springs 42 and so that the carriage is yieldable vertically in either direction, but will normally be held c When thelug is engaged'between the latches 44 and/l5, the cage 'is locked in its normal up-f right position. The upper latch 44 is pivoted intermediately at 47 tocarriage 41, and has a short upper arm 48 adapted toengage a fixedstop 49 'so as to limit theoutward movement of the lower arm of the latchwhich engages the lug 46. A third arm 50 on the latchmember is pivotally connected with a rod 51 which extends up throughsa spring 52 which acts to normally hold the latch 44 yieldably in the positionshown in the drawings. However, when'the cage 1 is rotated clockwise, (Fig. 5) the lug 46' on the cage willdepress- 29 the latch 44against' the action of spring 52' until the lug 46 reaches the position shown in the drawings, at which time the latch 44 will springback in engagement withthe upper face of the lug. The lower latch member 45 is pivoted intermediately at 53 and has a lower arm'54 adapted to engage afixe'dstop 55' tohold the latch in the locking-position shown, Arm 54 has a pin and slot connection 56 with a'crank arm 57 extending upwardly from a I 80 rock shaft58 which extends longitudinally parallel with the axis of the cage It is to be understood that all of thelatch mechanism so far described is duplicated at each end of the cage. A manually operable lever'59 is secured-to one end of rock shaft 58, so that by moving this'lever in a counter-clockwisedirection (Fig. the lower'latch members45 will be swung inwardly'out of engagement with the lugs 46 so that the cage is released for rotation in a clockwise direction. Acam lug 60 on the lever59 is adapted to engage-a starting switch 61 of any approved type, when the lever is swung-inthe direction to release the latches 45, this switch 61-serving to complete the first electrical contact for controller 39 to initiate the cycle of rotatingmovements of the cage 1. After the rotation of thecage has commenced, the manually operable lever'59 is moved back to the normal position shown in the drawings and afterthe cage has com pleted one revolution the lugs 46 will snap into place between the latches 44 and'45 so as to'lock the cage in normaljupright position.-

Of course the controller 39 will stop the motor'33 at this timeso that; power isno; longer being applied'to the i cage to rotate -same.

Since the entire latch assembly is'fioating be- I tween the compression spr1ngs'42 and" 43, it

can yield to some extent in either direction to fi -cushion the shock of stopping the cage. I

It will be understood that the 'electric'con; trolling connections for motor 33 include a cut-out switch and reversing-mechanism (not here shown) so that the" rotation of carriage 1 can; ifnecessaryabe stopped'at anypomt 111- -.tion, in an obvious manner.

In such case, the lower latches 45 will yield inwardly to permit thelugs 46 to, return to locking posi- The stationary tracks 62 and'6, 3 leadingtO and from the cage projectiihto the annular end shieldsi2l' and 22 so as tomeetthe re'spec-v' tive ends, of tracks -l4-int-he cage; These inwardly projecting endsot tracks 62 and 63 are,

carried by cantilever I-beams- .64 securedto fixed anchorages 65. It will be understood 7 that ,a'continuous train of carsjoined by swivel connections are moved through this 1 apparatus, so that when one caris carried by the cagel and rotatedto dump its contents,

the immediately adjacent cars will remain stationary on the fixed trackways 62 and 68.

In order to prevent the coal or other ma terial from spilling out of the ends'of the cage 1 during the dumping operation, the an-' nular end shields 21 and 22, hereinabove reierred to,.are provided, these shields project 111g outwardly around the ends of the fixed tracks 62 and 63. These shields can be'extended without difliculty :far enough to ene velop'the ends of the next: cars at each end of the dumper, and will catch perfectly all lading that may fall over the endofthe car or may be crowded'off during rotation of the dumper. Each of the cylindrical shields 21 and 22 is finished at the outer end by an in wardly extending annular ring or flange 66, the outside diameter of which is the diameter. V

of the cage, and the inner diameter ofwhich may be the least diameter that will clear the car and its lading. A substantially semicircular: shield. 67 is hung from the beams 64 which support the fixedrails 62 and 63.v

One of these cars, as shown 5 in Fig. 5', has awidth suficient to substantially fill the passage 3 between the-sidewalls l5 and 16. Car-holding angles are secured to the-side walls 15 and 16, and angle brackets 71 secured to the respective sidesofthe car engage under the fixed angles 70 as the 7 car moves. into the cage: These inter-engag ing angles will support the car in an obvious manner during the rotation of the cage. It will be apparent that the spill shields 17 and 18 built inthe cage extend radially substan tially from the opposite side edges of the upper open side of thecar so that substantially all of the mater'ial held within the car will be directed outwardly through opening i the dumper .is rotate Another standard type of car is illustrated in Fig. 4, this car being much narrower than the passage 3. For cooperation with this type of-car, pivotedcar stops'or horns are .provi'ded to swing up and engage-over the wheels 72 of the car, thus holding the car down against the supporting rails 14. Means Sis provided to automatically engage these horns with the wheels as thecar moves into.

position within the cage, and to release the hornsafter the dumping operation has been completed. There are two independently op-- 'ei'able' sets of horns 73 and 74, the horns 7 3 being adapted to engage the front wheels of the car as it moves into position within the cage, and the horns 7tsubsequently engag ing the rear wheels after the car has been .tstopped against the front horns 7 3. Substan-f tially identical means is provided for automatically movin'geach set ofhorns 73 and 74:

In Fig. 3 both set-sot horns-are shown locked in released position, but the horns "T3 are shown in dotted lines after; they have been moved to locking position. Each set of'horns, (for example the. horns '74), are mounted at their lower ends on shafts 75, which are mounted for rockingmovement 1nthe cage structure. Crank arms/76 secured to shafts are connected through links 77 with the oppositely projecting lever arms 78 and79 of a rocker member centrally pivoted at 80 on a fixed bracket81. An upper arm-82 of the rockermember is pivoted at 83 to a rod or link 84 which projects througha compression spring 8 5, so, mounted as 'tonormally move the 'rockerniemberto the position shown in Fig; 7

member which actuates the horns .74. A cam lug 97 formed on-the' bottom of bar 90 is adapted to engage behind a fixed stop 98 in the cage frame, as shown in Fig.3 3, and thus holds the rocker in this position against the 7 force of spri ng85, with the horns 74L in released position, as shown in Fig. 3.

A second latch bar 106 (see dotted lines Fig. 3) is formed with a slot 107 adapted to 1 receive the stud 87 on the. rocker member which operates the other pairfof horns 7 3. Latch bar 106 is mounted parallel with the bar 90 but spaced laterally thereform, as indicated in Fig.1, and is connected at one end 1 with the rock shaft 88 by alcrankiarm simidown at its other end by a spring pressed rod similar to the rod 92. jThe latch bar 106 has no cam lug similar to 'the ,lug 97 i on bar 90,] and the slot '107 1 in bar 106 is much shorter than-the slot 96 in the bar '90, so that when-thelatch bar 106 is raised, the slot 107 may be completely released-from the stud 87 on the rocker meme 7 berg -As shown'inFig. 3 in dotted lines, the

" A crank arm 118 extendinggupwardly from "rock'shaft88is connected by link 119 with fthe shaft 120 of a releasing roller 121. Shaft 120 is also supported by links 122 pivoted at Y their upper ends 123 in the cage frame.

When the horns are in released' position, as

indicated in solid lines in Fig. 3, the roller '121 will be in "the position shown in that figure; When the-horns are'moved to locking Q engagement with the wheels 72 of the car,

the r0ller'121 will be projected outwardly through. ai suitable opening ins'the casing of the: cage, to the position shown in Fig. 1. As the cage 1 approaches the end ofits rotation, roller 121 will engage'the fixed cam 124 "mounted adjacent the cage, and will be again pushed into the position shown in Fig. 3 to return-the horns to their unlocked" positions.

" In describing the operation of this car 1 loclii'ngmechanism, we will first assume that the parts are all in the released positions indicated in solid lines in Fig. 3.' As-a car moves into the cage,' the cam or lug 105, positioned beneaththecar, will first engage the 'le'ver arm 117 ,jwhichthrough the'link and ,"lever connections previously described, will "elevate the lumbar-106 torelease the pin 87-onth'e rocker-which actuates the horns 73.

The corresponding spring' '85''will now ex pand to swing the horns '73 upwardly to the dotted line position indicated in 'Fig. As *the 'forward' wheels '72 of the can'move forward into engagement with horns .73, the cam "105 will engage the second lever arm'104, thus liftingthe other -latch4bar-90 so as to release the locking h1g9? ftrom'the fixed stop 98.
