The present applicationis a division of ‘our copending application Serial No. 483,508, ?led April 1'7, 1943, and entitled “Masts, poles, and the like.” _ a series of radially directed slots 8. When it is desired to connect together two members 4 and 5, the ends are brought into close proximity with one another and there is introduced between ‘the ?anges of adjacent members 4 and 5 a plate Ill provided with lugs II on either side thereof which are arranged in planes perpendicular to ~ This invention is for a union for, connecting together the sections of a mast and the like and ' has for its object theprovision of a union which is capable of :being manufactured by mass pro the plane of the plate It). . The lugs l l are spaced duction, is quickly assembled and enables a mast to be easily-erected by the-minimum number of . ‘ personnel, and capable of' being broken down into a small number of‘ parts which are easily around the plate In and from the axis thereof at distances corresponding to the distances between the. slots 8 formed in the ?anges ‘l and the dis tances of the slots 8 from the axis of each mem ber.
