The jack is actually called the <U>hopper</U> in this action, which is inherited from the old type upright sticker actions of the 1800's. The term hopper is used when the jack is directly or indirectly attached to the key. The term sticker applies to the wooden rods which connect the hammer shanks to the undercarriages, originally <U>glued</U> with leather hinges, hence the term "stick...er". </FONT></STRONG></DIV> <DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV> <DIV><STRONG><FONT face=Arial size=2>Before you upload a translation, please change your "rolls" to "roles"!!!
