538,322. Structural metalwork. KILPIN, A.B. April 24, 1940, No. 7403. [Class 20 (ii)] [Also in Groups XXXI, XXII and XXXII] A transverse tubular cantilever support or bearer connecting the body of a vehicle to its chassis frame is of rectangular section with its side walls parallel between the chassis longitudinals d, e and converging towards their outer ends, and is characterized in that it is built up from channel members such as a, b, Fig. 3, or m, n, o, p, Fig. 7, secured together at their edges along the neutral plane. or planes of the bearer. In the construction shown in Fig. 3 the bearer comprises upper and lower channels a, b, welded together at l; if the chief stress is horizontal rather than vertical the members a, b may be placed side by side with the welded edges l on the upper and lower faces. In the construction shown in Fig. 7 the bearer comprises four V- channels members m ... p welded together at l. The bearers are secured to the chassis d, e by bolts f which also secure plates g to which the body (not shown) is attached. Reinforcing plates or washers h are provided and also internal fillets k. Butt or lap joints may be used, and the channel members may be secured together by rivets or bolts instead of by welding. The walls of the bearer may be corrugated to increase their strength. The converging ends of the bearer may be formed by slitting it as shown at r in the right side of Fig. 8 and welding the edges thus formed as shown at s on the left side of this Figure. The ends may converge either as seen in plan or in elevation.
