The rib members land the bond members 2, 3, :3 are made in the form of tubes provided with longitudinally extending grooves or ?anges, into ing of sheet-metal onto said framework. The invention is substantially distinguished by the which the roof, the windows, the wall sections at the crossing points, preferably through weld edge of the sash, said edge portion being grooved and the external covering are fitted. They are feature that the wall sections are secured with 10 preferably made from steel bands whichare rolled to a suitable pro?le and bent into tubular their upper edges to the tubes extending along shape and united at the‘ edges thereof, for in the upper sides of the Wall sections, by means of stance by welding. As shown in Figure 3, .the a longitudinally extending flange on the tube roof stringers 2 are provided with two‘ channels formed by bulging the tube outside the cross-sec tional pro?le thereof, the wall sections being pref 15 29, 2! embracing the edges of the plates it, I? and formed ‘by bending the edges of the steel ‘ erably secured with their vertical edges in grooves band. Otherwise, the stringers are of such cross provided in the Vertically extending tubes, which sectional shape that the intermediate portions are formed by the tube wall being dinted-in in located between the grooves and the tubular por— side the cross-sectional pro?le of the tube. This tion form indentations or channels 22, 23, one of arrangement makes it feasible to apply the sheet which 23 receives the edge of the external roof metal covering on the outside of the tube frame cloth l9 which is retained by means of a clamp with simple means and without the use of spe 24 inserted into the channel 23, said clamp con cial securing members in the form of screws, sisting of a steel band resilient in the transverse rivets or the like, and in a manner such that the 25 direction and having a cross-sectional shape cor wall attains a smooth external surface. responding to the profile of the channel. Said The invention will be described more closely indentations or channels 22, 23 may be resilient, with reference to the accompanying drawings. so that the connection between the roof and the Figure 1 shows a wall portion of a car body viewed roof stringers attains a certain elasticity, where from the outside. Figure 2 shows the same wall by the strains on the material and on the joints portion viewed from the inside. Figure 3 shows are equalized. a cross-section of the wall portion to a larger The window panes are ?tted into the appur scale. Figure 4 is a cross-section on line 4-4, tenant sashes through the intermediary of ?llets Figure 5 a cross-section on line 5-5, and Figure 25, 26 from elastic material, such as Para-rub 6 a cross-section on line 6—6 in Figure 3. The body frame consists of a framework which 35 ber, the same being provided with an internal channel, into which the edge of the pane is ?tted in itself is of sufficient rigidness to be able to ab so as to be tightly embraced by the’ edges of the ‘sorb the forces acting upon the car body, and channel. The ?llets 25, 26 form a frame in one which is composed of ‘transverse rib members I or more pieces, which is ?rst arranged on the ‘ and longitudinal bond members 2, 3 and 4. The glass pane, whereupon the rubber frame is ?xed rib members and bond members are constituted in place in the sash by being forced over the inner by tubular frame pieces united with one another or suitably pro?led to provide a tight joint and a ing. The rectangular sashes thus formed con secure engagement between the rubber frame and stitute frames in which are mounted windows 5 and wall ?llings ‘6, l. The framework is carried 45 the sash. Thus the rubber frame serves at‘ the same time as a means for tightening and secur by longitudinal girders 8, between which are ar ing the edge of the pane to the frame, besides ranged transversely extending girders 9 adapted which it will effectively relieve the pane of strains . to carry the ?oor ID. The wall portions located underneath the windows are provided with an produced by shocks or through the resiliency of external covering of sheet-metal, the same being 50 the framework. The wall ?llings 6, ‘l, which may consist of ?bre boards, are ?tted in a similar man divided into.sections ll of a width correspond ner into the respective sashes by means of'rubber ing to the distance between the rib members. ?llets. The roof [3 is carried by the longitudinally ex The wall sections II, which form an external tending roof stringers 2, which are braced by transversely extending sheet-metal girders l5 55 sheet-metal covering on the frame Work, are se 2,411,226 3 cured with their upper horizontal edges into a ?ange 2'! formed by suitable pro?lation of the bond members 3, said ?ange being provided with a groove 28 formed in the lower edge thereof, this groove being adapted to embrace the sheet metal edge with a resilient engagement. The lateral edges of the sheet-metal members H are bent and secured in grooves 28' in the rib mem 4 2. In a car body, a frame including horizontal and verticaltubes rigidly secured together, spaced and mutually cooperating resilient ?anges formed longitudinally on each horizontal tube and lying outside of the tubular cross sectional pro?le thereof, and wall sections disposed tangentially of said tubes and each having smooth and ?at upper edges resiliently‘ gripped and frictionally bers l by means of wedges 29 forced into the ‘ held between said resilient ?anges, said wall sec grooves. The lower edge of the sheet-metal 10 tions having inturned vertical edges, the vertical members il may be freely suspended or con tubes having grooves lying inside the tubular cross nected to the body frame or to the lower portion sectional pro?le thereof receiving the inturned of the wall.

In a car body, a frame including horizontal sectional pro?le of the tube, the sheet-metal 15 and vertical tubes rigidly secured together, spaced members H may be caused to join the outside of and mutually cooperating resilient ?anges formed the vertical rib members I, as will be seen from longitudinally on each horizontal tube and lying Figure 3. outside of the tubular cross sectional pro?le By additionally securing the vertical edges of thereof, and wall sections disposed tangentially the sheet-metal members I l in grooves 28’ formed 20 of said tubes and each having smooth and flat by dinting-in the tube wall inside the cross-sec tional pro?le of the tube, the joint between ad jacent Wall sections may be made entirely smooth, upper edges resiliently gripped andv frictionally held between said resilient ?anges, said ?anges‘ being formed on the portions of the tubes exter as will appear from Figure 6, so that the wall nal to the car body and means on certain of the in its entirety will have a smooth external sur 25 mutually facing portions of the horizontal and face. verticaltubes for securing window frames thereto. The invention may obviously be applied to ve ll.
