Definitions

  • My invention relates to railway car roofs and more particularly to that type ofI railway car roof which is self-sustaining ⁇ and wherein a plu,- rality of metallic roof sheets span from side plate to side plate of the car and are connected thereto and Which preferably have raised panels along their adjacent margins and upstanding nan'ges along their adjacentedges rigidly connected together to form a load sustainingstructure.
  • Each of the roof sheets is pitched or arched ⁇ from a central ridge portion toward the side plates and the metal in the portion on each side o'f the ridge is disposed in upper and lower planes forniing the aforementioned panels.
  • the panel is usually formed therein throughout the length of said sheet with the ends of said panels merging into the plane of the sheet approximately at the eaves where the sheet turns downl over the side plates of the car, thereby functioning as beams between the side walls ofthe car.
  • the panel is of constant depth and width throughout its length, and the sides of the panels are disposedat an angle as close to a right angle to the' plane of the sheet as practicable, thus giving greater strength to the panel.
  • Another object is to form a plurality of panels in each sheet, said panels extending from adjacent opposite ends of the sheet', overlapping each other at the approximate transverse centerA of the sheet, and merging into said sheet between the transverse center of the sheet and the end of an adjacent panel, sothat adjacent panels form, in eifect, a beam between opposite ends of said sheet.
  • a further object is to space said panels so that the webs of the panels are spaced equal distances apart at the ridge of the roofso as to substan-l tially equally distribute the strength of the sheet along said ridge.
  • Still another object ofthe invention is to form adjacent panels so as to provide a diagonally

  • Figure 6 ⁇ is a plan view of a car roof sheet showing still another modied form of the invention.
  • Figure 7 is a combined section on line 'l-l of Figure 6' and side elevation thereof.
  • FIG. 8 Sand 10 are cross-sectional views on lines 8-8, 9 9 and
  • Figure 11 shows a means of uniting adjacent roof sheets by automatic welding.
  • My invention is shown as einbodied in a oar roof comprising metal side plates of substantially Zsshaped cross' section which extend from' end to end of the car and have a portion l disposed horizontally to rest upon and be secured to the tops of the longitudinally spaced vertical side posts (not shown) of the car. From the outer edges of said portion l depends a flange 2 which overlaps the upper outer edge of the side posts, and at the inner edges of said portion I an upstanding flange 3' is provided, it having an inwardly turned reange 4 extending in the plane of the roof ofthe car. ⁇
  • The' car roof comprises a plurality of roof sheets 5 each preferably having a pair of panels 6 formed therein, said panels extending ⁇ from adjacent opposite ends of the sheet, overlapping' each otherV and merging into said sheet between the transverse center of the sheetV and the end of the other panel so that said panels form, in effect, a beam between opposite ends of said sheet.
  • these panels are preferably pressedupwardly from the plane of the roof sheets andare of constant depth from the ridge toward the eaves, but as they approach the eaves, the panels decrease in depth on a gracefulV curve to the side plate reilange 4 upon Awhich the roof sheets rest and are curved down thereover and secured to the vertical flange 3V thereof, as by the row of rivets indicated at 1.
  • Each pair of panels functions as beams and carries any loads imposed thereon to their supporting side plates and, therefore, the side walls or webs 8 of the panels are formed as nearly at a right angle to the plane of the sheets as practicable, thus affording additional strength to the panel as a beam.
  • the weakest point of a beam is that area midway between its points of support, it becomes desirable to strengthen that area, if possible.
  • the pair of panels in each sheet as being of substantially like scalene triangular form, with the vertices 9 of each pair overlapping so that the longitudinal central area of the sheets between the two vertices 9 has pressed therein four side walls or webs 8 instead of two as in the remainder of the sheet, which remainder, however, is close to the supporting side plates, and thus does not Aneed as much strengthening.
  • the central otherwise Weakest portion of the panel is materially strengthened, thereby accomplishing the primary purpose of the invention.
  • roof sheets are formed with upwardly turned flanges I8 which abut, and adjacent sheets are held together by a seam cap I I overlapping adjacentA flanges and all secured together by a row of rivets, indicated at I2, as is common in this type of roof.
  • the roof sheets are disposed diagonallyacross the car from side plate to side plate thereof, which, when the car is moving will tend to deflect water thereon along the seam caps and 01T the car rather than tend to drive the water under the seam caps as might be the case when the roof sheets are disposed at right angles to the car sides. Also disposing said seam caps diagonally will provide a gusset action and thereby increase the strength of the roof.
  • the side walls or webs 8 of the panels are preferably formed substantially parallel with a line 21 drawn between opposite ends 28 of adjacent seam caps, thus in cooperation with the space 29 between the panels at the ridge forming a diagonal stiifener between the ends 28 of the seam caps. Furthermore, the space 26 between said panels and seam caps form, in effect, depressed panels further cooperating with the raised panels and seams to provide a strong roof structure.
  • the running board I3 is supported in any acceptable manner, as by the brackets I4 secured to the seam caps by the rivets I2.
  • the roof sheets 20 are disposed at right angles to the sides of the car and the panels 2
  • the overlapping panels 25 are of constant width but yet overlap at the longitudinal center of the car, thereby strengthening the ridge area of the roof.
  • each triangular panel occurs adjacent one end of the sheet and each panel extends across the sion 31 between the panels 36 extends from end to end of the panels between the adjacent diagonal and parallel webs 40 thereof, and also it will be noted that the outer webs 4I of a pair of adjacent panels in this modification are parallel with the sides 46 of the sheet and with each other. Thus each triangular panel extends from adjacent one end of the sheet substantially but not entirely across the sheet.
  • the panels 36 and stilener 31 therebetween have been designed so that transversely across the sheet at the center they are of equal width, and furthermore the spaces 38 between the outer webs 4I of the panels and the adjacent upstanding flanges 39 at the sides of the sheet are equal in width to the width of the panels 36 at the center of the sheet, as clearly shown in Figure 8.
  • the meeting margins 41 of adjacent sheets are preferably secured together (by use of a separate element, as shown in Figure 2, or by forming the sheets, as shown in Figure 8) to form a stifrener or carline between opposite ends of the sheet, or in other words, between the opposite side plates or side walls of the car.
  • the webs of the panels and the stifeners are equally spaced apart along the ridge or longitudinal center 43 of the roof so that the strength of the several panels (that is the roof) is equally distributed throughout the length of the car.
  • Figure 11 shows means for joining two adjacent sheets together by automatic welding equipment
