Abstract

193,104. Handoll, P. G. Nov. 3, 1921. Cleaning internally. - A percussive tool for scaling boiler tubes has a hollow piston member f, with cutting edges f<4>, f<5> at the ends, reciprocated to strike each side of the tube in turn by fluid pressure supplied by a pipe c. From the position shown the piston is driven downwards until the port k is closed, exhaust taking place near the end of the stroke past flats f<6>. Pressure in the space i then reverses the piston. Forward scraping edges a<1> may be formed on the body. Reference has been directed by the Comptroller to Specifications 15450/05, 3113/14, and 104,099.
