As shown in Fig. 1, the Wheels 1, on the rails 2, support the rotary car axles 3, the axles in turn supporting the axle boxings ings support the car side sills 5. The relatively light and flimsy lading holding body 6, may be of either sheet metal or of wood, and may be retained in its proper working position with respect to the side sills, by. the flat strap irons 7, which may be termed the belts or binders, the terms applied to similar flat iron straps used for similar purposes in the old type mine cars. Across the ends of the car, there are commonly two horizontal fiat iron braces 8, one on each end, see also Fig. 2.

face plate, when first Bumpers The car, as shown in Figs. 3 and 4, has the spring bumper consisting of the bumper face plate 9, the transverse bumper block 10, of wood, the fibres or grain of which, are at least approximately, at right angles to the side sills, the 11, a leaf .spring, see Fig. 5, and plate 12. w

, The bumper bolts 13, Fig. 3, one on either side, may' hold the bumper face plate, the bumper block, the bumper spring, and the spring face plate, all in working position. By unscrewing the bumper bolt nuts 14, access to 15, in the bottom plate the spring face moved for examination, whole or in part. I My improved bumper face plate 9, Figs. 3 and repairor renewal in -4, formed. up out of a sheet metal blank, is in cross section horizontal U-shaped, as in Fig. 4, inner edges have the longitudinally of the car, within the bumper review similar to Fig. 18, showing vawith part broken away, of

Except for the bolt holding seats, this is substantially the old style center bumper plate 9F, in use for many years, and usually formed up out of the rectangular sheet metal blank 9G. Evidently, it now only remains toshear the inner edges, and to punch the rivet slots and bolt holes, as shown in Figs. 3 and 8.

The bumper block 10, Figs. 3 and 4, consists of a transverse wooden beam, the 'ends of which abut against the vertical inner sides of the Z-bar side sills 5A. The grain of the wood is at least approximately parallel with the end beam-channel 17, so that the bumper shock is at right angles to the grainof the wood.

The vertical side of the bumper block next the end channel, is hollowed out to receive the bumper spring face plate 12, and the bumper spring 11, (Fig. 5), the object of the spring face plate, being to prevent the spring from cutting into the bumper block. Before the spring is entirely flattened out, the wood block comes to a bearing against the end channel, thus cushioning the final impact.

If the bumper spring 11, and its face plate 12, Figs. 3, 4, and5, be omitted, and the bumper block 10, replaced by the also transverse wooden bumper block 10A, Figs. 8 and 9, wide enough, as it appears in Fig. 9, to be held by the bolts 13, againstthe vertical member of the end channel 17A, as shown, Figs. 8 and 9, there will thus be provided a sol d springless bumper, which neveraction. Some varieties of wood are slightly comacross the grain, so that this improved springless bumper may still be cushioning in its action, in that it cushions the compressive haulage shocks, which otherwise tend to loosenthe end sill riveting, and thus shorten the life of the equipment.

Draw-bars wood) is also cushioning in its.

The form of readily detachable draw-bars shown in Figs. 3, 4 and 6, consist of the upper draw-bar 19, and the lower draw-bar 19A. The reaction plate 20, is riveted or bolted to the rear vertical face of the upper draw-bar, as shown, and is held in place by the nuts 21. The shock plate 22, is permanently riveted to the upper inner faces of the main double diagonal end beam member 23. The draw-bar slot or notch 22A, Fig. "l, in the. shock plate, engages the lower drawbar, and assists in keeping the draw-bars from swinging side ways, while a trip of cars is being pulled around a curve, although the two nuts 21 are in a position-to take care of this reaction, without other assistance.

The shock plate however, prevents the abrasicn of the main double diagonal end sill brac- The reaction plate 20, Fig. 4, is just below the shock ,plate 22, so that the reaction plate is held down bythe shock plate. The stop block 24, riveted to the front face of the lower draw-bar, also rests against the under side of the shock plate, and also serves tohold the draw-bars in their correct positions,

With this arrangement, the extra cost of spring draw-bars as compared with rigid draw-bars, is very little more than the extracost of the springsthemselves.

This also applies to my spring bumpers as compared with the rigid bumpers heretofore in use. The increase in weight, in either case, is also al- 'most only that of the springs,

The angle which the end beam diagonals make with the side sills, may evidently be varied within considerable limits.

The end channels 17, Figs. 3 and 4, may simply bear against the double diagonal web members 23, at their centers, but without being riveted to the same, as shown. The riveting of the end channels, to the double diagonal web members, as in Figs. 8 and 9, will however, bind together better, the end sill structure.

as liable to vertical displacehaula e shocks.

Wing support In addition to the horizontal end brace 8A, Figs. 13 and 16, for example, the two vertical end braces 32, riveted to the horizontal .end braces, and resting on some suitable support, have been in common use. This method of end support answers well enough, where the wings are of relatively shallow depth, as in Fig. 18, but where the wings are of approximately the same depth as the remainder of this new type car, as in Fig. 16, some additional means of end support will be required. This may to advantage be the vertical double inclined end brace 33, riveted along its upper horizontal central portion, through the lading body end, sheet 6A, to both the horizontal and vertical end braces, as shown, as well as riveted or otherwise suitably attached to the end belts 1A, at their outer ends as shown.

The distance between the axles is commonly, at least approximately, about one-third of the lading body length, so that over axles 3, Fig. 13, will be a for the wing supporting cross channels or beams, 34. .Over the axles is however a suitable place for derailed, it is also of advantage to be'able to get at the rails where the car wheels should bearon the same, these wheel recesses also serving this second purpose. The tops of these wheel recesses, also herein termed the wheel housings, will also require support, so that over the axles is again a suitable location As shown in Fig. 15, thewing and wheel recess supporting cross channel or beam 34, rests on and is riveted to the upper flanges of the Z-bar supporting side sills 58, its ends being riveted to the lading siding the cross channels or beams, I for other reasons, which will appear further on.

ing outward;

for one set of wing supports.

6B, and to the structural angle side brace 35, which latter is in turn riveted to the belts 7A.

The lading siding 60, over the wheels, also herein termed the wheel housing cover plates, may evidentl y be. riveted to the under sidev of siding resting conveniently upon the upper flanges of the longitudinal side sills,-under the cross channels, as shown. This cross channel is evidently but an extension of the same principle to the wing body support, as the longitudinal supporting side sillsbear to the main car body.

.In combination with the main belts 7A, Fig. 17, may be used the double inclined belt braces, 7B,

the central horizontal portion of which rests on the Z-bar side sills SE, from which points the belt braces slope downwardly to meet the outer portion of the main belts which support the sloping wing bottoms, being there riveted to same, as shown. This combination makes what is known as a truss, and may be made amply strong for the purpose, at a relatively small cost. At the lower outside riveted what may be termed special angles 36, conforming to the shape of the corner, as shown,

and flanged at their top edges, and protecting the corner against abrasion. These special angles will serve admirably for engagement with the cradle dump, as the dumping strains will thus be delivered to the supporting side sills.

In much'the same way, however, the side bracing channels 35, Fig. 17,

willalso serve, admirably, for engagementwith the cradle dump, as they will also deliver to the side sills, the dumping trains, the side sills in dumping strains to the several belts, and thuswithout material strain on the relatively light and flimsy lading holding body, at any one point particularly.

For the longer cars now in use, five belts 7A,

Fig. 13, will be a convenient number, which may be arranged, as shown. In this case, the four special angles 36,

are connected with the two pairs'of end belts.

This will give the cradle dump a connection with the side sills, by means of two belt trusses and the two car end plate trusses, amply sufiicient for the purpose.

Where the service is severe, evidently the belt truss shown in Fig. 1'7 may also be used in con- 1 nection with the end plate truss shown in Fig. 16, while the wingsupporting channels may be used in place of the belt trusses, also in connection with the endplate trusses. Plate trusses may also evidently replace either the belt trusses or the wing supporting channels.

The side bracing angle 35, Figs. l5'and 16 as well as 1'], may extend the whole length of the car, see also Fig. 13. The special function, however, of this angle, is, to of the wings, in the middle of the car, from bulgthese angles being kept from spreading themselves by means of the wing supporting channels; 34, hereinvalso termed cantilevers? Evidently, then, 35, Fig. 13, may be replaced by the shorter side bracing angle 35A, Fig. 14, attached at its ends, to, say the two belts '70, at the farthest sides of the wheel recesses.

The right and left vertical sides of the wheel When the car is turned over side ways, to be turn delivering the keep the vertical sides the side bracing angle the cross channel, the inner edges of this lading 1 corner of the wings, may be two on either side of the car,

The axle may also have an inverted U-shaped housing 41, Figs. 2 and 19.

and end sills, binds together In Fig. 23, the vertical sides 6G, of the wheel housings, herein so termed lading wing supportand riveted to the same. I

Evidently, in the manner described, the wheel housings may thus serve as an economical and efficient means of wing support.

A vertical plate 49, Fig. 23, mayconnect the car bottom 16 and the wing brace 33A, in part to support the bottom, and in part to stiffen the wing brace from being bent down near the center by heavy pieces of lading. This plate will also stiffen against buckling, the flat strap strut 50, which latter keeps the lower parts of the side sills weight of the wings and lading, independently of the lading bottom rivets.

The side stiffening angle 35A, Fig. 23, extends from the right vertical side, as shown, of the right wheel recess, Fig. 14, to the left vertical side of the left wheel recess. Therefore, there may be only two of the double diagonal wing supports, 33A, between the two ends of the car, one at-either end of the side stiffening angles. This will reto" the lading within the traction truck proper; Where the double diagonal wing braces or supports, 33A, are used betv jeen the ends 'of the car, it will reduce the number of different parts in to also use this form in place of the end brace 33, see Fig. 16.

In my application #424,132, filed Nov. 15,1920,

short inclined or sloping wing body supporting braces, similar to the short-braces 333, Fig. 2 were disclosed, but without the tie rod 51, which may be over the car axles. The outside lading body double inclined. cross braces 33A, Fig. 23, which as shown, are continuous from end to end, may be termed outside lading body double inclined crossbraces, in order to distinguish the same from the short sectional inclined cross braces previously disclosed.

With the double inclined cross braces 33A, the weight of the outside lading'body, on one side of the truck, is the weight of the outside lading body on the other side of the truck. The double inclined cross braces 33, Fig. 15, and 33A, Fig. 23, as being transverse of the car, will also be herein designated as transverse integral double inclined supporting members. Somewhat similarly, the cross channels34, Fig. 15, and 34A, Fig. 19, will also be herein designated as transverse supporting beams, and again also as transverse supporting members, which term also obviously include the cross braces 33, 33A, as Again, somewhat similarly, the lading end closure 6A, Fig. 16, is obviously reinforced by the double diagonal cross brace 33, and will therefore be also herein designated as a diagonally reinforced lading end closure. Again,somewhat similarly, the lading siding proper 613, Fig. l3, is reinforced by the horizontal angle 35, and will therefore be also herein designated as horizontally reinforced lading siding.

For cradle dump cars, the wing supporting cross channel 34, Fig. 15, for instance, may be a built up channel or angle, of greater depth than shown, top is ievi with the top of the car, in which case, the car may be considered as consisting of three separate compartments. I

Instead of the one belt 7A, Fig. 13', there may for example be two belts'lF, Fig. 1.4, between the wheel recesses. one closely adjacent to either of the two adjacent vertical faces of the wheel housings.

The lading siding 6, Figs; Land 2, may be put inside the belts, but putting the siding outside the belts, as shown herein, gives something of a gain in capacity without increase in cost.

The cast steel draw-bar 19D, Figs. 25 and 2'7,

2 may evidently replace the two wrought draw-bars 19B and 19C, Figs. 8 and 9, for example, which .as being transverse of the car,

latter may also be welded or otherwise suitably united, for the purpose.

As shown in Figs. 25 and 2'7, the cast steel drawbar 19D, may be said to consist of the vertical downwardly extending channel-shape shank 19D, and the horizontal draw-head proper 19E; the slide plate 25, and the reaction plate 20A, being riveted to the rear and front of the vertical part of the draw-bar shank, as shown. The spiral spring 51, with its seat 52, may evidently replace the leaf spring 27 of Figs. 8 and 9.

The pressed end channels 1'7, Fig. 4, and 17A, Fig. 9, etc., also evidently be replaced by equivalent forms, as for example, by the special channel 17B, Figs. 26, 2'7 and 28, formed up out of the sheet metal blankrol'lB, Fig. 28, in a manner similar to that in which the double diagonal end brace 23B, Fig.3, was formed.

What appear asthe horizontal. flanges of the end channel 173, Fig. 2'7, may have an outside edge, which when viewed from the top, as in Fig. 26, is the sector of a'circle, and thus approximately parallel to the adjacent and outer edge or face of the-bumper face plate 9, and of the bumper block 10. The bumper vertical bolts 53, held in place by theif nuts 53A,- are passed, as shown, through the end channel, the bumper face plate and bumper block, as one method of retaining the bumper face working position. The structural angle 54 may be riveted to the vertical sides of both the side and end sills, secure them together.

The bumper leaf spring 11, Figs. 3, 4 and 5, also herein termed the bumper transverse leaf spring,

The outside lading supporting cross channel 34, may replace the double inclined end braces 33, Fig. 16.

The angle which the bottom part or nearly horizontal portion of the belt 7A; Fig. 16, makes with the web plate of the side sill 513 may be varied within considerable limits. If this angle is made 90 degrees, or a right angle, the car than becomes, in end view, a rectangular or box car. As shown in Fig. 24, the bottom portions of the belt 7G, with the attached lading siding 61, may also be made more sloping toward the center of the car, than also 4 approximately rectangular in side view, while the said lading holding body shown in Fig. 15 may also be said to be approximately rectangular in end view, more particularly in so far as lading. capacity is concerned. The term rectangular lading holding bodies is therefore to be understood to include lading holding bodies which are approximately rectangular, both transversely and longitudinally of the car.

The boxings 4, Fig.1, and 4A, Fig. 14, may be said to be integral side sill reinforcing axle boxings, to compensate for the metal removed from the side sills 50, Fig. 12, thus making the holes 48 for the insertion of the axles 3, Fig. 14, and a portion of the axle bearing proper, as per my ap- #676,326, filed Nov. 22, 1923. (Now Patent No. 1,530,333, dated March 1'1, 1925.)

As shown in Fig. 19, the lading holding body, as a whole, consists more particularly of the lading end closures 6J, the lading wing lading siding proper 6K, the lading wing lading bottoms 6L, and the traction truck lading bottom 1613. All of the said lading bottoms are plate and bumper block, in
