UNITED .TATES mien w. sanroan. or xNoxmtE, TENNESSEE ILWAY CAR Application led Hay @.1928. Serial No. 276,016. ,i

This improvement lrelates particularly to mine cars which are intended tobe loaded in the mine and brought 'out of the mine in a train or trip and moved over a track and I a across a tipple for discharge of the mineral through the bottoms of the cars while the cars are crossing the'tipple, the object being to attain quick discharge of the loads from all the cars.

it@ For an example et cars of this type, reerence is made to United States Patent, No.

` 1,268,390; granted to me June d, 1918. 2in

the car of that patent there is a main frame composed of two relatively long side sills and 'te endstructures connecting the ends oi the side sills. The side sills are shown as consisting of metal channels, the webs ci :the

channels being npright and the danges being turned outward horizontally and the two sina@ gle axles extending through hxed bearings in the webs of the side sills..

The mining operation, particularly coal mining, is now entering a new phase. The operation is becoming almostentirely mechanical. Loading machines are being introduced to dispense with men. The prob-"f lem, therefore, oi obtaining a satisfactory car for mechanical doading has become acute.

The loading machines can load the cars quickly, but a great deal of time is lost in car shifting. The successful use of coal loading and coal cutting machines depends, therefore, on using a mine car of as large capacity as possible. The head room being limited and the tracks being curved, the mine car capacity hasA been limited to short wheel base designs of relatively low height. The short wheel base requires short overall len h.

Some mine cars are dumped by tilting and discharging material fromthe front end. A second method consists in rotating' the car sidewise and thus discharging its load.

These methods are not suited to use with lar e cars carrying heavy loads. The wear an tear on the cars and on the tipple structure is excessive.

A Coal `mining Acars equipped with four wheels and two axles need flexibility in oing around curves. For that it has been ound necessary to use loose wheels on axles.

There is a limit to the load that can be put on one bearing for loose fit. Particularly .does this refer to the roller bearing type of wheel, which is most always the easiest running. Most roller bearings are not case 55 hardenedor ground and there is a limit to the load they will stand. The largest standard roller bearing equipment which can econome ically be supplied in mine cars has three inch axles. Two such axles will handle a'lload of en ive or six tons and no more. Hence, a car which is to haul a heavier load must have more axles. v

The problem has thus arisen to provide a mine car large enough to hold as much as ten e5 tons of coal, in order that the cutting machine and the -loading machine can be used most eiiciently-cut and load more coal without car shifting. The car has to be exible for curves and flexible on the tracksto adapt it 1?@ to run on uneven tracks. Accordingly my present invention is described as including a body having its main part extended downward farther than insimilar cars and preferably having two trucks each of which has 75 two axles and four wheels and is swiveled.. This car can be made as long as permitted by the. track curves, and the capacity can be brought u to a ten ton load. Thus the height can e kept within limits. But, using 80 the trucks has heretofore necessitated placing the side sills high enough to be above the trucks, and so placing the structure parts supported by the side sills as to avoid extending any of those parts downward over the 85 outer faces of the wheels. The bottom discharge or dumping being between the rails on which the car wheels run, the discharge opening has necessarily been as narrow as the space between the rack rails. And here- 96 tofore the side sills in these truck cars have been spaced from each other a distance a proximately equalling the width of the d1scharge opening. Thus the side sills have been placed 1n 'upright planes which extended 9.5 downward near the inner faces of the car wheels. The side walls of the c ar body have been supported on the side sills and extended ,obliquely outward and upward from the up er edges ofthe side sills. From the upper hne .10

of this slanting part of the wall, another part extended upward in an upright plane tothe height of the car. rl`he port1on of the body wall extending outward needed to be slanting (not horizontal) in -order to cause the coal in the side parts of the car body to slide to the discharge opening when the bottom doors were opened. Placing the side sills at such height and that near each other resulted in placing the lower edges of the slanting parts of the body walls high above the track.

By lowering the slanting parts of the car body walls, more space is provided in the lower part of the car body. Thatis desir,- able, because it has become desirable to increase the load capacity of these cars. Such slanting parts can be lowered by moving the side sills bodily outward horizontally or approximately horizontally, the slanting body walls then resting on the side sills and extending obliquely downward toward the middle of the car. lf the side sills are of channel-form, it is preferable to tilt them outward sidewise to the slant oit' the slanting walls and place the web of the sill iatwise against the outer face of the slanting walls andjoin the web and the wall by riveting. By thus tilting the sills the slanting wals can be placed still lower while the sills remain at the same elevation. When the side sills are thus moved bodily outward, opportunity is given :for varying the height or the sills above 'the track. For then the side sills are out of the range of the car wheels, and the sills may be supported on a cross member which is supported on the wheels, the support of the cross member on the wheels being, i' desired, at an elevation different from the elevation of the sills.

The principal object ofthis invention is to edectsuch tilting and outward removal of the side sills and thereby edect such lowering orn the slanting parts of the body side walls. As will be described further on, each side sill is given a new Y osition against the lower or outer face of t e slanting part of the body side wall.

As above stated, the main part of ythe body structure in my improved car is the frame consisting of side sills and end structures or end sills. ln that frame are two side sills, A, A, and two end structures or end sills, B, B. ln the i'orm shown in the drawings,

the side sills are metal channels separated from each other farther than the width of the discharge opening in the inished car body structure and each sill having a web, Al, and danges, A2. ln other similar cars as heretofore built, that width has usually been equal to the distance between the trackv rails on which the car is to run. ln my present car, the side sills are parallel to each other and they are shown extending lengthwise as far as the side walls of the upper part of the car body extend. ln lieu of being placed to bring the webs, Al, of the sills into the upright position, these sills are turned or tilted outward sidewise to bring the webs to the slant that is givenl to the adjacent parts of the body side walls, the flanges, A2, being turned obliquely outward and downward.

At each end of the car, the adjacent ends of the sills, A, A, are joined by an end sill, B, which extends horizontally from one side sill to the other. The chief element of this end sill isa member formed by bending plate metal to produce an upright web, B1, and an upper horizontal flange, B2, and a lower horizontal ilange, B3, similar to the main element of the end sill structure described and illustrated in my Letters Patent of the United States, No. 1,486,547, granted to me March 11, 1924. On the lower ilange, B3, rests a iiling member, B4. A buffer member, B5, extends over the outer part of said filling member and over the upper face and the lower tace of said member. Av coupling pin, B6,

lll)

' of ordinary form extends downward through the flange, B2, and the buffer member, B5, g1; filling member, B4, and the lower flange,

The meeting ends of the side sills and the end sill are joined by corner angle members. (Figs 11a, 11b and 3a.) Each such member has a wing, C, lying against and riveted to the web, B1, of the end sill. Another inclined wing, C1, extends across the adjacent end of the side sill and along the outer inclined face ofthe web, A1, of the side sill and is riveted to said web.

The side sill and the end sill are further joined by means of a metal top plate, C2, which extends across the upper face of the upper flange, B2, and is riveted thereto and also receives the coupling pin, B6. At each end said plate extends obliquely downward over the upper flange, A2, of each side sill and is riveted to said flange. At the back of the end sill, B1, an angle bar, C3, has its horizontal web bearing against the under face of the top plate, C2, and is riveted thereto and has its upright flange resting against the adjacent web, B1, of the end str)ucture and riveted to said web. s (Fig. 3a

Above each truck is a lower transverse frame member, D, and an upper transverse frame member, D1. The member, D, is straight and crosses each side sill immediately below said sill. Said member,-D, is shown in the form of a horizontal channel having itsflanges turned downward. The

lmember, Dl, is also shown as a metal channel. It has its flanges turned upward, its web resting upon the web of the member, D, and secured thereto by rivets. Each end of the member, D1, is turned upward obliquely and made to rest on the upper face of the adjacent side sill. A cast iron filling block, D2, is shaped to rest on the web of the transverse member, D, and to bear against the lowerface of the web of the side sill. Bindfing bolts,rD3, extend through the web of the transverse member, Dlthe web of the' side sill, the filling block, and the web of the lower transverse member, D. Thus the side sill and the transverse members, D and Dl, are firmly bound to each other. verse members, D and Dl, are auxiliary to the end sills in the carvbody frame.

Each transverse channel member, D, is supported by one of the trucks, as next described.

Each end of the frame Vformed by the side sills and the end structures and the transverse members, D and D1, is supported on the track rails, R, by means of a truck having two axles, Wl, and two wheels, W, mounted on each axle. The axles rest in bearings, W2, supported on channel members, W31" The channel members are joined to each other by` rreans of transverse mem- The trans-- bers, W4, placed in upright planes and having their en'ds abutting against the channel members. Angle members, W5, are joined to the members, W4, and the channel memmembers, W6 and D, are turntable blocks, lfV? and W8, theI lower block, W7, being seaty ed in and secured to the channel member, W6, and the upper block, W8, being fitted into and secured to the channel member, D. A king pin, W9, `extends through the channel member, D, and the blocks, W7 and W8, and the channel member, W6. Below the channel member, W6, a nut, W10, is applied tothe king pin. In each end of the lower channel member, W6, is placed and suitably secured a pillow block, yXVll; and above each of said blocks there is placed in and suitably secured to the channel lmember, D, acorrespending' pillow block@ W12. The blocks W1lareseparatedfrom the blocks, W12, sufficiently to allow some sidewise rocking of the car body or tilting of the truck in passing-Wer irregularities in the rail track.

At each side of 'the car body a lower side plate, E, extends obliquely aero/ss the upper face of the adjacent side sill, A, and is secured to the side sill by rivets or bolts. Between the trucks, each lower side plate, E., extends obliquely downward a little beyond the inner plane of the adjacent truck wheels, W, and then downward to form an upright part, El, which extends nearly to the level of the top'of the track rails, R. The end edges of the parts, El, are upright. The lower edge of said part, El, is bent outward to form afiange, E2. Upright gusset plates, E4, are inserted between that flange and the lower flange of the adjacent side sill and have flanges bearing againstthe .side sill lower flange, A2 and against the flange, E2,

and against the adjacent face of the side plate, and the part, El, of the side plate and said gusset plate flanges are riveted` The gusset plates are omitted from Figs. 3,

4 and 5.)

Near and at opposite-sides of the middle I transverse, upright plane of the car, a bearing plate, E5, is riveted to the outer face of zontal door hinge rods, I. These r'ods exten'd from one side plate part, E1, to the other and through said parts and the bearing plates,

E5. Each projecting end of each rod receives a nut, I2. At the inner face of the adjacent side plate part, El, each rod has an annnular shoulder, Il. (Fig. 4;.) The bottom doors are supported by thesehinge rods, as will be described further on.

Each side plate, E, extends obliquely upward beyond the side sill, A, until it meets the lower edge of the upper side plate, E3. Above the part, El, the end edges of the plate, E, extend obliquely upward toward the ends of the car. The horizontal edges of the plate, E, and the plate, E3, are suitably secured to each other, as by overlapping and riveting. The upper plate, E3, extends upward to the upper edge of the car body.

Each end of each upper side plate, E3, extends obliquely endwise and upward. to the end of the car body and thence upward along the end of the car body.

At each end of the car body, an end plate, E6, extends from one upper side plate and the adjacent lower side plate to the other side plates and has itsedges secured to the adjacent edges of said other plates by means of angle bars, E7, bolts or rivets joining the angle bars to the plates. The lower ed e of each end plate, E6, extends downwar between the other plates close to the adjacent bottom door, as will be described further on.

At the forward end of the car a cross bar, L5, bears against the outer face of the adj acent end plate, E6, and is suitably secured to said plate. This is a means of reinforcing the end plate and the angle bars used for joining theend plate to the side plates.

Binding straps, E8, extend over the outer face of the upper part of each side wall, E3, and are folded over the outer or upper flange, A2, of each inclined side sill and extend over the outer or lower face of the web, A1, of the side sill, and said straps are riveted to the adjacent walls and side sills. Thus the walls are reinforced and are firmly bound to the side sills, whereby greater firmness is given to the body of the c ar.

Thispart of the car body is further reinforced by two standards, Ll, which rest on the top plate, C2, and bear against the outer face of the end plate andare suitably secured thereto as by riveting. On the lowerend of each standard is a foot, L2, turned away from the body of the car and resting on and riveted to the top plate, C2. At the rear end of the car body, standards, L1, are applied as at the forward end of the car. Forward of these rear standards, a reinforcing plate, L3, has its lower edge turned horizontally forward and has each end resting on a foot plate,

:,saaae'r L4, which Arests on the upper face of the adjacent side sill. The foot plates and the plate, L3, are riveted to the side sills and to each other. The upper edge of the plate, L3, is riveted to the end plate, E6.

At the forward ends of the parts, E1, of the side plates, E, an extension end plate, M, reaches horizontally from one of said plates, E, -to the other and across the ends of said plates and has an upper oblique part which overlaps the under face of the end plate, E6, and is riveted thereto. The ends of the extension plate, M, are extended and folded to lie against the adjacent outer face of a reinforcing plate, M1, lying against the outer face of each part, El, of the side plates, E, and each folded end is suitably secured to the adjacent reinforcing plate, Ml, and the plate, El. This extenslon plate, M, serves to connect the end plate, E6, and the plates, El, to each other, whereby this downward extension structure is made stronger. To the downward extension structure are to be added the automatically-controlled plate metal doors, F, G and H.

A horizontal door hinge rod, F2, has its ends resting in bearings formed in the plates, El and M1, and the folded ends of the extension end plates, M. Hinge members, F1, are applied to the rod, F2, to support the door, F.

Hin e blocks, I3, are applied to the hinge rods, ,"to support the forward ends of the doors, G and H. The upper faces of these blocks, I3, are shown concentric with the shafts on which they are supported, and the adjacent part of each door is correspondingly curved and secured to the blocks. The forward door, F, and the middle door, G, are curved downward between their ends. The rear edge of the front door, F, rests onthe forward edge of the door, G, when these doors are in the raised or closed position. The rear edge of the door. G, rests on the forward edge of the door. H, when these doors are in the raised or closed position. The hinge blocks, I3, and the forward ends of the doors, G and H, extend forward beyond the hinge rods, I, sufficiently to allow the doors, F and G, to pass the adjacent shaft for downward turning of said doors. On the rear edge of the rear door, H, is a latch arm, J, which is positioned to be engaged by the latch hook, Jl. when said door is in the raised position.

The hook, J 1, is extended downward from the transverse arm, J 2, which is pivoted on the pintle, J3, which extends through the binding plate, J4. and the hanger, J 5. and the arm, J2, and the upper part o`f the hook, J l, said part of said hook being channeled horizontally to receive the arm. (Figs. 2, 3, 4, 4a, 5, 8, 9"and 10). Said arm and said hook are joined by bolts or rivets. The ends of the binding plate, J4, are ysecured to the end wall, E6, by means of ears, J6,

assess? which extend from the ends of the binding late. The upper edge of the' binding plate, 4, is bent obliquel to bear atwise against the outer face of t e end plate, E6, of the car body, and said edge is riveted to said end plate. It is to be noted that the arm, J2, and the hook, J 1 constitute 'a bell crank l turning on theA pintle, J3. Upward movecome disengaged from the rear edge of they next forward door, G. That door being tionary cam member, K, (Fig. 10) is placed nowfree, it falls by reason of its own weight andthe. weight of the material resting thereon. That movement of the door, G, by turnin on the axial line of the adjacent shaft, causes disengagement ofthe forward edge of the door, G., from `the rear edge of the door, F. The door, F, being now free, it falls (turning on the hinge rod, F2) due -to its own weight and the weight of the material resting on that door. When in their lower osition, all the doors extend into the s ace tween the trackv rails, R.

For suc releasing of the door, H, a stabeside the rail track in posltion to engage the loweredgeof said arm, J2, when the car'reaches the place at which the discharge of its load is to be made. f

To limit the downward movement .of the i bell crank arm, J2, when the latch arm, J,

' the hook is pushed in the reverse `and below the latch arm, J.

' rial from the car body ment with a stationary cam member,

has been released from thehook, J 1, a bracket, J 8, is placed on the rear body plate, E2, in position to extend below the arm, J2, to engage the latter when it has descended far enough to brinA the hook into the path of the latch arm, On the lower end of the hook, J 1, is an oblique edge, J7 ,which is normally held in 'the path of the latch arm, J. (Fig. 8.) When the rear door is raised, said latch arm bears against said oblique edge and pushes the hook laterally until said arm is above the hook, ywhereupon the greater weight of the bell crank) arm, J2, causes the tilting of the/bell crank whereby ldirection As already herein stated, the opening ofy these doors and the discharge of the mateare to take lace while the car is p'assmg over the tlpple or otherstructure throu h which the dischar e is to be made. e continued forwar movement of the car brings the lower face of the forward door, F, into enga located between the track rai1s, R, and supported on the ties T and rising to a sufricient height to force the rear end of said door upward a little wayabove its normal 1 or closed position. Said cam member is extended horizontally far enough to maintain its'engagement with the forward door until the door, G, has in the same manner been engaged by the inclined portionof said cam member and has been forced upward theref' bya little way above its normal or closed position and until the rear door, H, has been in the same manner forced upwardruntil the latch arm, J, has moved upward and' forced the hook, J1, sidewise and until said arm is above said hook and the hook has va resumed normal position. Then, with. the passing of the forward door, F, out of engagement with the cam member, K1, the rear part of said door descends by gravity and .again rests on the forward part of the middle door, G. When the door, G, passes out of engagement with the cam member, K1, said door descends and its rear edge again rests on the forward edge'of the rear door, H. When the door, H, passes out of engagement with the cam member, K1, 'it de.- scends by avity until the latch arm, J, e11-l `gages the ook, J l. Thus all the doors are again in their normal or closed positions and the car body is again ready to`receive a new 95 load.
