Abstract

The assembly for guiding tool or bit attachments of pneumatic hammers, e.g., picks, uses a conventional barrel, housing an intermediarily flanged shaft of circular cross section, which is elongated so as to be a sliding fit for the flange, thus containing the shaft laterally and longitudinally whilst in use. Pref. the guide barrel is integral with the hammer barrel or a suitably joined separate element. A sleeve within the hammer barrel locates the reciprocating half of the bit in the hammer, this sleeve being of uniform internal diameter or of irregular form e.g., conical.
