Abstract

322,399. Marks, Sir G. C., (Ingersoll-Rand Co.). Feb. 18, 1929. Percussive tools.-A tool retainer of bent wire attached to trunnions on the barrel is formed with a yoke G and two inner coils P, these latter being so shaped that when the retainer falls into the postiion shown dotted in Fig. 2 they engage the collar E on the drill steel on its upward stroke and so prevent the accidental release. Shallow grooves L are formed on the barrel to help keep the retainer in position.
