Abstract

25,910. Blumer, L. Nov. 13, 1912, [Convention date]. Flexible metal tubes.-In flexible metal tubes of helically coiled interlocking strip, having an internal helical strip covering the grooves of the tube and constrained to partake of the movements of the outer strip by a projection which enters the grooves, the overlapping edges of the internal strip are made tight by packing a housed in a groove in the strip, and the protuberance due to the presence of this groove engages, without play, a groove in the outer tube.
