Abstract
299,605. Baxenden, T. G., and Collyear, J. R. Oct. 19, 1927. Bobbins and reels.- Metal spools, bobbins or reels, more particularly spools for photographic films, are made by forming the end metal discs with a hollow boss of a size and shape just to accommodate the end of the cylindrical body portion, and then subjecting the boss, with the end inserted therein, to an endwise pressure or blow, whereby the end of the body is tightly gripped in the crushed boss. Figs. 1 and 4 illustrate two forms of bosses, b, b<1> accommodating the end of the cylindrical body c. The bosses b<1> instead of being annular may be segmental, and the body c formed with projections fitting therein.
