5 Claims, 10 Drawing Figures PATENTEDJAH 23 I975 SHEET 5 OF 6 INVENTORS Jf/T/n/offfiou 155270 OPETT/ ATTORNEYS I RAILWAY CAR WITH ELASTIC SIDE WALLS BACKGROUND OF INVENTION The present invention consists in a railway car with elastic side walls for carrying crops and discards coming from a slabbing mill.

As said crops, the weight of which may reach up to one ton, pass from said containers onto railway cars by falling freely from a height of 3-5 meters, the need arose of substituting for the conventional railway cars with stiff side walls special cars the side walls of which, carefully designed as for their shape and size, could bend so as to transform the kinetic energy of the falling body into an elastic deformation energy of the striken side wall element and adjacent ones, removing thus from said action the strike effect and consequently avoiding any permanent deformation.

SUMMARY OF INVENTION The object of the present invention is to provide a railway car with elastic side walls for carrying crops and discards coming from a slabbing mill comprising a stiff frame on which are fastened shaped sheet strips, according to their longitudinal direction, substantially C- shaped, which are arranged adjacent to each other transversally to the car longitudinal direction and are connected to each other by at least a pair of longitudinal sheet strips extending preferably between the car ends.

Said sheet strips, shaped according to their longitudinal direction, are C-shaped and comprise exactly a horizontal rectilinear central section with at the ends thereof two rectilinear upward inclined sections, two curved sections and finally two further rectilinear sections substantially vertical though slightly inclined towards the car inside.

The rectilinear central section of said shaped strips is connected to the car frame, correspondingly to the ends of said rectilinear central section preferably by bolts; the ends of said shaped strips being connected .to each other, each by a sheet strip arranged longitudinally to the car axis, which is securely connected to the car head walls; the connection between the longitudinal strips and the shaped strips being obtained preferably by bolts.

Between each shaped strip and the adjacent one there is left a free gap which is large as the strip width and preferably as wide as a fractionof said width.

The car frame comprises a substantially stiff framework covered on its top by a continuous sheet; on the two long sides of the car being arranged two .low side walls suitable to contain, together with the .car head walls, a layer of filling materials, preferably represented by slags.

The car head walls are made of channel-shaped sections arranged horizontally and overlapped to each other with their concavity directed towards'thecar outside; suitable stiffening uprights being arranged on the outer faces of said head walls.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the above listed figures, which relate to a single particular solution of a railway car improved according to the invention, numeral 1 denotes a set of sheet strips longitudinally C-shaped and comprising a flat central section 101, an upward inclined side section 102, a connection joint 103 and finally a rectilinear section slightly inclined towards the car inside and acting as a side wall portion. Said elements are to be arranged adjacent to each other, transversally to the car longitudinal axis, and between each pair of adjacent elements a gap 104 is left free; each of said shaped strips is fastened to the car bearing structure, in this case to the upper wings of beam 106 by means of four bolts 19 shown only diagrammatically in the figure. The shaped strips 1 are connected to each other by means of a pair of sheet strips 2.which join longitudinally the upper end of section 104 of each shaped strip 1; said strip 2 is connected to the shaped strips 1 by means preferably of bolts 20 shown only diagrammatically in the figure; the use of bolts allows a relatively simple and quick replacement of the shaped strips 1 which ought to be replaced being broken, warped and the like.

The two ,ends of ,strips 2 are securely fastened, still by means of bolts 33, to the car head walls formed by channel shaped sections 3 overlapped to each other and with their wings directed towards the car outside, through suitable coupling plates 32; the twohead walls are connected to two short and stiff side members formed in the same way as the head walls, obtained by .meansof lugs 4 of channel-shaped sections overlapped in the same way as the channel-shaped sections 3. The

frame 18 of the caris covered at itstop by a continuous sheet .17 intended .for collecting chips of materials of any .kind, and particularly,.together with two sheets 8 acting asside walls, itmay contain a filling 107 where sheets are .partly immersed into, said filling being further suitable to absorb the shocks caused by the workpieces falling onto the bottom concerned.

Numerals 5,6.and 7 denote metal sections acting as stiffening uprights for thetwo head walls of the car; in

order to reinforce the connection ,between said uprights and the channel-shaped sections forming the head walls, reinforcing plates 11, stiffened by elements 12, are arranged in the groove of sections 3, and on said plates said uprights are welded.

Numerals 13, 14 and 15 denote the stud of a ladder, the coupling and the steps thereof respectively.

The arrangement works as follows: the crops and discards coming from cutting of flat bloom ends fall onto the described car hitting the bottom and side walls thereof, said walls under the shock action are capable of deforming elastically not only locally, as each of shaped strips 1 is connected to the shaped strips adjacent thereto through strips 2 which take part in said deformation.

The slag filling the car bottom is suitable to absorb the direct shocks which otherwise would be suffered by the central portion of the car bottom which is not in position to deform elastically.

Obviously, the form of the shaping of strips 1 may be modified, as well as the number of strips 2 joining said strips 1.
