Abstract

470,630. Percussive drills. ELOY, F. April 8, 1937, No. 10011. Convention date, May 22, 1936. [Class 124] A percussive tool for piercing the tapping holes of blast furnaces has its piston 4 formed with an axial bore 3 and extension guides 5. During the piercing operation the annular face 10 of the piston strikes an anvil block (not shown) carrying the piercing tool. For withdrawing the tool the anvil block is removed and the tool 20 passed through a guide 19, the piston bore 3 and a bush 30. It is then clamped by the eccentric clamp 14, 15 and back blows from the face 11 of the piston strike the bush 30 and through this to the clamp casing.
