Abstract

21,156. Maier, F. Sept. 25. Sockets.-A drill socket has a conical helical spring 5 fitting in the tapered shank 2 and held in position by a ring 6, its front end engaging a shoulder 4. Pressure on the drill 10 causes the spring to grip it; the drill is released by inserting a tool in slots 8 or 9 to press back the spring.
