24,558. Marsh, J. F. Nov. 6. Cleaning pipes and tubes.- For cleaning or scraping pipes and tubes, arms a carrying cutting-edges a' shaped like a round-nosed chisel are hinged directly to one boss f upon a screwed rod k and indirectly by means of links c to a second boss b. The boss f is fixed, while the boss b is pressed forward by a spring within an adjustable casing i. The arms have projections a<2> which, when the tool is in a tube, overlap so that the whole of the surface is scraped. The scale may fall through spaces m in the arms.
