The present invention refers to such car bodies which are intended particularly for omnibuses, and the roof, windows and wall sections of which are carried by a framework of horizontally and verticaliy extending tubes rigidly connected to each other, and the invention has for its object an arrangement to secure 'wall sections consist ing of sheet-metal onto said framework. The invention is substantially distinguished by the feature that the wall sections are secured with their upper edges to the tubes extending along the upper sides of the Wall sections, by means of a longitudinally extending flange on the tube formed by bulging the tube outside the cross-sectional rofile thereof, the wall sections being preferably secured with their vertical edges in grooves provided in the Vertically extending tubes, which are formed by the tube wall being dinted-in inside the cross-sectional profile of the tube. This arrangement makes it feasible to apply the sheetmetal covering on the outside of the tube frame with simple means and without the use of special securing members in the form of screws, rivets or the like, and in a manner such that the wall attains a smooth external surface.
The invention will be described more closely with reference to the accompanying drawings. Figure 1 shows a wall portion of a car body viewed from the outside. Figure 2 shows the same wall portion viewed from the inside. Figure 3 shows a cross-section of the wall portion to a larger scale. Figure 4 is a cross-section on line 4-4, Figure 5 a cross-section on line 5-5, and Figure 6 a cross-section on line 66 in Figure 3.
The body frame consists of a framework which in itself is of sufficient rigidness to be able to absorb the forces acting upon the car body, and which is composed of transverse rib members I and longitudinal bond members 2, 3 and 4. The rib members and bond members are constituted by tubular frame pieces united with one another at the crossing points, preferably through welding. The rectangular sashes thus formed constitute frames in which are mounted windows 5 and wall fillings 6, l. The framework is carried by longitudinal girders 8, between which are arranged transversely extending girders 9 adapted to carry the fioor ID. The wall portions located underneath the windows are provided with an external covering of sheet-metal, the same being divided into.sections ll of a width corresponding to the distance between the rib members. The roof [3 is carried by the longitudinally extending roof stringers 2, which are braced by transversely extending sheet-metal girders l5 provided with a Wooden filling It. it is: provided with double walls It, ll consisting preferably of wooden fibre boards covered by cloth l8, l9, said boards being united with the girders $5.
The rib members land the bond members 2, 3, :3 are made in the form of tubes provided with longitudinally extending grooves or flanges, into which the roof, the windows, the wall sections and the external covering are fitted. They are preferably made from steel bands whichare rolled to a suitable profile and bent into tubular shape and united at the edges thereof, for instance by welding. As shown in Figure 3, .the roof stringers 2 are provided with two channels 29, 2! embracing the edges of the plates it, I?
and formed by bending the edges of the steel band. Otherwise, the stringers are of such crosssectional shape that the intermediate portions located between the grooves and the tubular por tion form indentations or channels 22, 23, one of which 23 receives the edge of the external roof cloth l9 which is retained by means of a clamp 24 inserted into the channel 23, said clamp consisting of a steel band resilient in the transverse direction and having a cross-sectional shape corresponding to the profile of the channel. Said indentations or channels 22, 23 may be resilient, so that the connection between the roof and the roof stringers attains a certain elasticity, whereby the strains on the material and on the joints are equalized.
The window panes are fitted into the appurtenant sashes through the intermediary of fillets 25, 26 from elastic material, such as Para-rubber, the same being provided with an internal channel, into which the edge of the pane is fitted so as to be tightly embraced by the edges of the channel. The fillets 25, 26 form a frame in one or more pieces, which is first arranged on the which it will effectively relieve the pane of strains produced by shocks or through the resiliency of the framework. The wall fillings 6, l, which may consist of fibre boards, are fitted in a similar manner into the respective sashes by means of'rubber fillets.
The wall sections II, which form an external sheet-metal covering on the frame Work, are secured with their upper horizontal edges into a flange 2'! formed by suitable profilation of the bond members 3, said flange being provided with a groove 28 formed in the lower edge thereof, this groove being adapted to embrace the sheetmetal edge with a resilient engagement. The lateral edges of the sheet-metal members H are bent and secured in grooves 28' in the rib members l by means of wedges 29 forced into the grooves. The lower edge of the sheet-metal members il may be freely suspended or connected to the body frame or to the lower portion of the wall. By the fact that the flange 21 is formed by bulging the tube Wall outside the crosssectional profile of the tube, the sheet-metal members H may be caused to join the outside of the vertical rib members I, as will be seen from Figure 3.
By additionally securing the vertical edges of the sheet-metal members I l in grooves 28 formed by dinting-in the tube wall inside the cross-sectional profile of the tube, the joint between adjacent Wall sections may be made entirely smooth, as will appear from Figure 6, so that the wall in its entirety will have a smooth external surface.
The invention may obviously be applied to vehicles other than omnibuses, such as railway cars, tram cars and motor cars, as well as to airplanes.
