The Armstrong ratchet consists in a light but strong mal-leable iron ring, which carries the ratchet and pawl, andwhich is slipped over the barrel of the stock and securelyattached to it by a thumb screw. No extra handle is pro-vided as the extension is tapped to receive one of the stockhandles. It may be adjusted for turning the stockin either direction. This is a strong and thoroughly reliable tool thathas proved of great service and value to pipe fittersand engineers, enabling them to use regular Arm-strong stocks for threading pipe in positions whereotherwise they would have to take down the pipe.
