Myimprovement relates particularly to conplingfmechanism designed for the Vautomatic coupling of mine cars usedv on rail igaelrs Vwhich are unevenly supportedy and which have frequent and irregular curves and frequent changes in` grade.

Y 51e-mo nig.

One object of th invention is to provide a simple coupling'VV structure Which Will.

become. engaged automatically when cars are pushed endW-ise against each other un'- der. the varying eonditions mentioned above ani which coupling structure Will remain in engagement during pushing and pulling and jolting of the ears at varying velocityv on such irregular trackage as I have above indicated. l V A, 'further object of the improvement is to, provide such -a coupling'l structure in a Vo'rm 'which vvfill permit disengagement of 'the coupling structuresl of adjoining ears 'and putting said structures into such` posi'- tion as tol permit therrotating of. one of the cars-parallel Vto the length ofthe car without interference of the` coupling n or bumper elenjients or' one car with the coupling or bumper Vrelements ot the adjoining ear or car, this arrangement allowing a tra-in oi such cars to be moved progressively through a rotary tipple, the car o rcars at the time in the tipple being turned by the tipple for dumping, until all the cars have been thus emptied, and the cars being ac apte-d to automatic recoupling byV pushing or bumping the cars against eachother.

. it further object of the invention is to provide a bumper structure comprising bumper castings which are combined WithV the car bottom structure in an elfective manner. Y

in the accompanying drawings, Fig'. l is a plan showing ends of cars pro- Vvided with my improved coupling and bumper structure, the cars beingy in alignment' with each other;v

Reterring to said drawings, A, is the nood-.en car bottom. This may be two and. one-half inches thick. A1 a bumper block applied tothe lower. facenti the car "botable thickness, for example .twoand onehalllv inches. At each end of the car, the

tom and formed of Wooden plankv of suithorizontal section on the line, e

bumper, block projects beyond lthe lcar `bottom toward the adjacent end of 'the adjacent car to 'form fan abutment forv the vbumper casting. The bumper bloclr is'secured to the car bottoni by `means, oi vupright bolts which also entend through othenparts, as

will be described further on.

f The car: bottom, 'A, extends across the Width of the car and4 each end extendsv to, apilane which is upright and .perpendicular to the length of the car, -At the end of the ear shown bythe Vright hand Apart ofFigs. l, 2, @erfand l, the free end or the bumper block, A1, conforms to yand lbears yagainst the inner face of the lower 'lange,-B1`, of the riOht hand bumper casting, BQ Above enr the flange, B17, said bumper rcasting 'has a..

'At the right of Vthe-llanges, B1 and B2, the casting B, has "ahor-izon'tal floor, B3, which rests on theupper face of vthe Wooden bumperblock, A1.v At the rigl'it of said floor-is an incline, B4, which rises to bring its upper face, tothe^level of the upper face of the carfbottom, A, at a short distance toward Athelgn't Yof the adjacent end edge oi' the car'bottom. :"Tlience y saidcasting has a horizontal section which extends to the upper edge of .the adjacent end of the carfbottom. flange, 139, entends downward along-the end ofthe car betteln and. te the upper faee Qi' At ear/h. end :Qff the seethe bumper block. u y tion, tong-ue, IVE?, extends tow-ard the right Aall@ is. counter-snel@ t@ 'the errer face of. the ear bottom Midway Alietween freni the section,` B5, yandisV count@ 1..

ninas, inea-ne, E?, @at ndsfrearwardinto the upper face of the car bottom, The tongue, B8, is longer than the tongues, B7; long kenough to receive two bolts, as Vexplained further on.

The draw bar, C, extends lengthwise across the car bottom, preferably from one end ot' the carto the other, and in the form shown by the drawings, rests on the upper face of the4 car bottom and on the tongue, B8, and the section, B5, and on the incline, B4, the end of the draw bar being inclined to conform to the incline, B4. An. inclined bolt, C1, extends through the end of the d raw bar and the incline, B4, of the bumper casting and serves to bind the draw bar to said casting. In the plane of the line, 6 6, of Fig. l, which plane is upright and perpendicular to the length of the car, a bolt, C2, extends downward through the draw bar and the tongue, B8, and the carbottom, A, and the bumper block, A1, and the binder iron, C4, which is applied transversely against the lower face of the car bottom and the bumper block and extends upward at each side edge of the car bottom. Said bolt also extends through the middle tie plate, C5,

Vwhich extendsparallel to the length of the car and over-laps the binderv iron, (lt, and extends along the lower face of the bumper block nearly to the bumper casting flange, B1, where it is secured to tlielower face of the bumper block by an upright bolt, C7, extending downward through the bumper casting floor, B3, and the bumper block and the t-ie plate.

At the right of the bolt, C2, Va bolt, C5, extends through the draw bar, the tongue, B2, andv thel car bottom and the bumper block. In the plane of the line, 6*(5, an upright bolt, C5, extends downward through eachV adjacent tongue, B7, and the ear bottom and the bumper block and the binder iron, C4.

On the line, 5-5, four more bolts, C7, extend through the bumper casting floor and the bumper block.

At each side edge of the bumper casting an upright flange, B9, rises from the floor, B2, and is integral with the upper flange, B2, and extends from said flange to the flange, B5, andV is integral therewitl The two flanges, B1 and B2, of the bumper casting, B, together form a bumper casting wall which has its outer face curved in an upright plane and also in a horizontal plane.

Turning now to the left hand part of Figs. 1, 2, 3 and 4, A is again a part ot' a wooden car bottom and A1 is the bumper block. It is to be understood that there may be a separate bumper block at each end of the car or a single piece may extend from end to end of the car and each end of said pieceserve to co-operate with the ca-r bottom for securing and staying the bumper castings,r i

D is the bumper casting placed on the end of the car opposite the end which bears the bumper casting, A. This casting has a top plate, D1, and a vcross wall, D2, extendiii; 'dowiiward from the top plate. Alllxtending i to the right from the cross wall and downweird trom the top plate are outer or side walls, D3. To the right of the cross wall, the middle part of the too plate, D1, is omitted.

From each Yedge thus formed from the top,

each side wall, D5, to the adjacent inner upright wall, D4, and from each wall, D4, to the other wall, Dt; butthis part of the wall, D5, does not extend upward as high as the top plate, this part ot' the wall, D5, being left low to make room for the hook, as will'be hereafter described. The wall, D5, stands below the level of the lower edges of the walls, D5, D4 and the llanges,'D5.

This outer `cross wall forms the bumper face oit' the casting.

in the left hand part of each inner wall, D4, is a bearing, B7, which opens downward and receives the journal, E3, of the hook, E. rlhe hook, E, extends from its journal rightward between the walls', D, and across the wall, D5. The journal, E5, is only long enough to reach across the walls, D4. The

lower part of said journal rests on the bumper plate, A1. rlhus `the walls, D4, and the transverse wall, D2, and the bumper plate together form a bearing for the journal,

On each end of' the journal is a wrist, E4. rlliese wrists are located at the left and a little above the axial line of the journal. On the inner face. of the outer ycross wall, D5, and near each inner wall, D4, is an ear, D8, into which there is secured one eno. of a ``contracting coiled spring, E5, the other end of said spring being coupled to the adjacent wrist, E4. E, is a head,E1, on which is a point, E2, which is to engage the bumper casting, B of another car.

The end of the carbottoin, A, extends beneath the left hand part of the top plate, D1, and abuts' against the left hand tace of the cross wall, D2, that part of the top plate being counter-sunk into the bottom, A. The draw bar, C, extends across that part of the top plate. The bumper block, A1, lies beneath and bears against the bottom, A, and the cross wall, D2, and the flanges, D, and abuts against the inner face of the outer cross wall, D5. bumper block is slotted to make room for On the outer end of the hook, I
