Month in the Patent Office

Abstract

Means for securing together the halves 1, 2, no, 1, of an aeroplane wing constructed, e.g. as in Specification 767,674, comprises a bolt or stud 28 with a threaded shank 4 and a nut 8 having a coned exterior and a conical bore to receive a coned lock‐nut 9. The bolt is conical and engages a bore 16 in the wing halves, nut 8 engaging a conical bore 26. In another arrangement, a stud 5, no. 2 having threaded ends 4 is pushed, at a temperature lower than that of the wing halves, into aligned parallel portions 7 of bores in said halves, and nuts 8 are applied to the ends 4 and engage the coned bore portions 6. Lock‐nuts 9 are then screwed on the ends and engage the conical bores in nuts 8. The ends of the nuts having turning flats or recesses 18, 19 may be cut off flush with the wing surfaces, after tightening.
