Abstract

24,258. Jaeger, F. Oct. 28, 1909, [Convention date]. [Addition to 598/09.] Posts. - Aerial masts or posts of the extensible type such as are described in the parent Specification are made with the flexible strips contained within a series of telescopic tubes which act in the place of the spacing- pieces described in that Specification. The flexible strips are detachably connected round a common axis, and are adapted to be coiled for shutting-down the mast. The tubes 3 may be either of circular or rectangular cross-section, and the bands 1, 2 may, as shown in Figs. 1 and 2, be arranged to give a cruciform crosssection, projections 4 being arranged on the strip 1 to keep the strips 2 in place. As shown in Figs. 6 and 8, the bands 5, 6 may be arranged to give a rectangular cross-section, and instead of using spacing-stops 4, the bands may be interlocked so as to give polygonal cross-sections as shown in Fig. 16. In the construction shown in Fig. 9, the parallel strips 7 are held apart by a zigzag strip 8 placed between them.
