524,861. Panels. LINDSAY, H. B. Nov. 11, 1938, No. 32845. Convention date, Jan. 26. [Class 20 (iv)] [Also in Group XXXII] In a vehicle body, container, building or like structure provided with side and roof faces, edge-defining frame members of each of these faces are continued in curved form and in the same cross section to join edge-defining frame members of adjoining faces. The frame members may be of channel section and may receive the inturned edges of sheathing sheets which extend across the openings formed by the frame members, these edges being clamped by bars also received in the channels. As applied to a refrigerator car the underframe comprises crossbearers 11, side sills 12 and end sills which support a framework of channel bars having flat outwardly extending flanges 14. Some of the bars extend horizontally as at 15, 16 and are joined by curved corner pieces 17 to form the wall portions and others 21, 22 are connected by curved extensions 24 of the vertical members 23 to form the roof portion. The sheathing 43 is flanged at the edges to enter the channels and is secured therein by other inverted channels 29 secured by bolts &c. 36. The channels may be strengthened by clips to prevent spreading. The floor plate 37 is secured at the edges in a longitudinal channel 16 connected to an angle 13 secured to the side sills 12. The edges of the sheathing may be slotted to facilitate bending the plates to curved form for the corner pieces and the curved edges between the sides, and sides and roof. The flanged edges of the sheath plates are bent in an inward direction to form a lip which is engaged by the flanges of the channel 29 whereby the plates are tensioned when clamped in position, the distance between the bottom of the bend and the bottom of the channel 16 determining the tension in the sheath plates when assembled.
