Definitions

  • a car side should be free from rivet heads, unnecessary bulges and indentations in the side sheathing, and, although the rivets have been eliminated for sometime in the car building industry by the use of welding, irregularities such as bulges and pitting left after the welding operation has been completed have not disappeared. Attempts have been made to hide these blemishes by the use of paint in various manners, but their presence can be detected.
  • the present invention completely eliminates these undesirable irregular ties so that good aerodynamic qualities can be obtained andthe outer appearance of a car incorporating this nvention is smooth, regular.
  • FIG. 1 is an elevational view of a car side employing the present invention viewed from the outer side of the car, aportion of the car side being broken away;
  • Fig. 2 is an elevational view of the car side shown in Fig. 1, but viewed from the inside of I the car;
  • Fig. 3 is an enlarged longitudinal sectional view through a portion of the car side shown in Fig. 2 showing the relationships of the side sheathing, the stifieners, and certain side fram -the side sheathing, reinforcing stiffeners, and
  • FIG. 6 is a detail view of individual side sheet segments before being welded together showing the stiffeners in place;
  • Fig. 9 is a diagrammatic view of. the car side "and an underframe showing in an exaggerated manner the camber in the side and underframe;
  • Fig. 10' is a diagrammatic view showing the car side mounted on the underframe showing the condition which they assume after the car is disc completed andthecamberhasbeen'almostoompletely straightenedout:
  • Fig. ii is a vertical transverse sectional view through the car the view being enlarged and with parts omitted for the purpose of clarity:
  • a completed car side forming the 'subiect mat ter of the present invention viewed from the side includes an integral sheathing II, reinforced by stiffeners ll (Fig. 2) extending substantmlly over the entire inner face of the sheathing. These stifleners are placed on the sheathing so as to provide room for side framing members which comprise longitudinal mem-' bers (Figs. 2 and 5), including a side sill II, a belt rail 18, a window header II, a side plate 2
  • the integral sheathing ll comprises a plurality of relatively small sheathing segments or sheets 24 and 2! (Fig. 6), the former of which may be referred to as letter board panel sheets and the latter as girder sheet segments.
  • the window openings 28 are cut out of a plurality of letter board panels 24, and then the'stiifeners II are spot welded to the inner surface of all the letter board panels and girder sheet segments making up the side sheathing. This welding operation is performed is such a manner that each individual sheet is perfectly straight upon cooling.
  • complementary letter board panels and girder sheet segments II and II are placed with their adjoining edges 21 abutting, and are then are welded together to make up units of letter board panels and girder sheet segments 24 and 1!, respectively.
  • a plurality of these units. sufficient in number to make up the entire car side sheathing are placed with their complementary vertical edges abutting, and then are arc welded to form the integral sheathing ll reinforced by stifi'eners ll.
  • the sheathing so constructed and reinforced is straight and the outer sheathing surfacels smooth and substantially free from buckles and other irregularities.
  • stiffener are spot welded to the individual sheets by applying the electrodes to the inner surface of the stiffeners so that the cavities caused by electrode pressure appear on the stiifeners rather than on the outside of the sheets. It is contemplated in the present invention that the welding shall be done in this manner.
  • the car side frame is completely welded together in a separate jig apart'from the side sheathing in any well known manner and then. after it has been straightened, it is placed against the inner face of the completed side sheathing, after first grinding flush the weld headings on the sheathing, with its various fram- .flve-dghths of an inch.
  • the window opening is indicated as being entirely in the letter board panel sheets, but obviously it can be divided between the adjoining.
  • each reinforced sheet 14 and I! must be straight before the entire sheathing is welded together, and this straightness must be "frozen" into the sheet.
  • the outside sheathing may be .078 of an inch in thickness.
  • the sheathing ll may be supported on a vertical jig, generally indicated at '35, by clamps 3', which suspend the sheathing buckles b1, properly anchored atone of their invention has completely overcome this difficulty.
  • the stiffener-s Ii are spaced apart so as to allow clearance for the side framing members, so that the side frame maybe applied directly against the sheathing II.
  • the frame then, is welded directly to the sheathing, I
  • stiffeners ll substantially cover the innor face of the'sheathing in the areas between framing members.
  • the side frame and sheathing are during the welding heat takes place before the two are Joined. In this manner the side frame is free to expand and contract without in any way affecting the sheathing and likewise the sheathing can expand and contract without being restrained by the frame.
  • the car side is fabricated separate and apart from the remainder of the car.
  • the underframe likewise is fabricated separately. Both the side and the under-frame may be cambered-to compensate for bending caused by the added weight on the underframe of the various parts and equipment making up the completed car body.
  • FIG. 9 the car, sideis indicat d at 4
  • the camber in these two members has been exaggerated in order to make it visible on such a small scale.
  • the degree of camber in the side and the underframe is approximately the same so that these two parts can be joined.

  • underframe per se forms no part of the present invention, for purpose of illustration in Fig. 11-th e underframe is shown to include a center sill 43 and cross bearers N.
  • the car sides and the underframe are joined at I the side sills in some suitable manner.
