Definitions

  • vvel'riclezweight is to use light metals such as aluminium alloys wherever possible in place of the steel previously -used but;..in '-genera], the design of wagons usingv aluminium alloyshasmerely followed the design of steel wagons without any real attempt being made to redesign so"tl'fatmaxirnum weigh't savings can be achieved.
  • a subsidiary-object of the invention is toprovide a rotarytype dump wagon (i.e., awa'gon'which"nraygbe': placed in a roll-over mechanism'forunloading) having the above advantage.
  • the wagon of the invention canb'evconstructed' pri marily from aluminium alloysto-achieve maximumweight saving, but it will be realised that theadesign is also applicable to steel constructionand particularly-to wagons constructed from high tensile.
  • steelz According to the invention there is providedxa-raih way wagon body comprising a longitudinal centre:sill;- a-bolster of curved cradle formation supported from said sill at or'adjacent each of itsends, a sk'in 'orshell having its lower area of curved configurationitto'match
  • the upper edgesofithe' channels 12 may be provided with integrally-extruded additionalflanges 18 as illustrated in FIG.
  • the lower plates 16 of the sill section 10 Adjacent each end of the sill 10 flanges 24, 26 with apair of spaced connecting webs 2851f so desired, the lower plates 16 of the sill section 10 may .belocated only adjacent the bolsters 22 and ap-' basementte bridging connections 32 may be welded to the lowerpartsof the channel sections at spaced locations in the length of'the sill.
  • the body shell- 34 is supported on the bolsters 22 and hasa curved configuration substantially throughout.
  • each bulkhead welded transversely of "and "within said skin” or shell, the external configuration of' each bulkhead being substantially identical with the: required crosssectional internal shape of the shell; each bulk-head. extending upwardly substantially to the'upper extremity of the shell at least adjacent each side' of the shell," and I a longitudinal stringer on each side ofsaid wagon sup-- ported from said bulkheads, the upper'sections of said shell being curved inwardly and I connected to said stringers.
  • FIG. 1 is a plan view of a wagon according to the in-- vention.
  • FIG. 2' is a side elevationalview of th'e wagon partly
  • the wagon of this embodiment hasacentre sill-10 which is preferably a box section made up from apair of spaced, extruded aluminium sections in the form of 1 channels 12 arranged with their webs-14in an vertical plane.
  • the lower flanges of the channels are connected 1 by welding to a plate 16 and theupper flanges maybe similarly connected.
  • the shell has a substantially flat base where it sits on the sill 10 'and fora short distance beyond the sill j:
  • the shell'then follows a relatively small radius throughan angle ofapproximately 90 to the point of greatest width.
  • the upper section of the shell curves inwardly at a greater radius.
  • the sides of the shell are connected at their upper edges to longitudinal stringers 36, and the overall curve selected for the shell is such that, assuming the wagon to be fully loaded and the shell to be substantially supported from said stringers, the stress in the shell approachespure tension-with little if any bending stress. This'enables the thicknessof the skin to be reduced to the minimum subject'topractical considerations such as thewear and tear andknocks'which railway wagons receive in use; v
  • the ends 38 6f the shell may be of curved configuration asseen in plan view, but are preferaby straight and I slope inwardly from their upper edges towards their lower edges as illustrated in the drawings.
  • each bulkhead in the present a case is'substantiallyin the shape of a horseshoe having: a relatively heavy spreader section in the lower area of the shell and tapering upwardly at each side of the shell to the upper edges of the latter-to act as supports for stringers 36.
  • the outer surface of each bulkhead 40 is shaped to conform to the required internal shape of the shelli
  • the shell extends substantially the full length of the sill as seenin FIG. 2and the end walls 38 of the body are welded inside the ends of the shell as also shown in FIG. 2' and are strengthened by horizontal stiffeners 58 of I-section welded horizontally across their end surfaces. The stiffeners are also welded to the internal surface of the shell.
  • a pair-of transverse stringers 62 are welded to the ends of longitudinal stringers 36 and to the upper edges of the ends 38 of the shell.
  • a bolster 22 of" curved cradle configuration is welded to the sill.
  • Each: bolster is of box section, having upper and lower the longitudinal stringers are provided with grooves 64 as illustrated in FIG. 3 adapted to receive the upper edges of the shell.
  • the shell is made in two halves, each of which has its upper edge engaged with one of the longitudinal stringers and its lower edge abutted against one of the shoulders 20 of sill 10.
  • the tipping mechanism usually includes a pair of vertically spaced horizontal beams arranged at each side of the track and adapted to be moved horizontally to engage the sides of the wagon preparatory to the tipping action.
  • suitable arrangements are made in the area of each of the bulkheads. Preferably there are three such bulkheads, one in alignment with each of the two bolsters adjacent each end of the wagon, and the third located approximately at the centre of the length of the wagon.
  • plates 70 are attached to the outer surface of the shell at the position at which the shell is approximately vertical, i.e., at the point of maximum outward projection of the shell.
  • Plates 70 are preferably made of manganese steel for durability. In this case they are attached to the surface of the shell by means of bolts. In cases where plates 70 are made from an aluminium alloy they may be welded to the shell.
  • a pad 72 bolted or welded to each end of each bolster.
  • a bracket 74 which is welded to the outersurface of the shell and which is provided with a pad 76.
  • each bulkhead having its lower area of curved configuration to match the curve of said bolsters, a plurality of spaced bulkheads welded transversely of and within said skin or shell, the external configurationof each bulkhead being substantially identical with the required cross-sectional internal shape of the shell, each bulkhead extending upwardly substantially to the upper extremity of the shell at least adjacent each side of the shell, and a longitudinal stringer on each side of said wagon supported from said bulkheads, the upper sections of said shell being curved inwardly and connected to saidstringers.
  • a railway wagon body as claimed in claim I including three of said bulkheads, one substantially in alignment with each of said bolsters and the third located substantially mid-way between said bolsters.
  • each of said bulkheads comprises a substantially flat base connected with acurved section of relatively small radius through an angle of approximately and an upper section curving inwardly about a relatively large radius.
  • a railway wagon as claimed in claim 3 including a plurality of plates each attached by welding to the outer surface of said shell along its line of greatest outward projection and in alignment with'each side of each of saidbulkheads for engagement by an upper.
  • a railway wagon body as claimed in claim 1 having end walls which slope downwardly and inwardly and are welded within said shell.
