Abstract

Tubular aircraft members have their ends shaped to the form of a fork with two oppositely disposed partly flat tapering prongs stabilised by a bridge‐piece having flat ends lying on and rigidly connected to the flat ends of the prongs. Fig. 1 shows a tube 1 having an end shaped to form prongs 2,3 between which a fluted bridge‐piece 4 (Fig. 2) is secured by rivets 7 which also serve to secure external reinforcing members 10 riveted to tube 1 at 11. Fig. 3 shows a means for connnecting a number of mutually inclined tubular members to a main member 12 of tubular or other section. A ∪‐shaped bridge‐piece 13 is bolted to member 12 and members 18, 19 shaped as shown in Fig. 1 are bolted between flat sides 15 of bridge‐piece 13 so as to lie in the same plane with member 12. Further tubular members may be connected to tube 12 in a similar manner but in a plane at right‐angles to the containing tubes 18, 19 by means of a second ∪‐piece 29 secured to a flat side of ∪‐piece 13 by the bolts which secure the latter to member 12. ∪‐piece 13 is fluted and apertured as shown. ∪‐piece 29 is offset on bolts 22 to bring as great an area of its base on the flat side 15 of ∪‐piece 13. The tubular member may be formed by bending steel strip, causing the edges to approach one another. These edges may or may not be connected together.
