Sliding inthis reciprocating ram, is another, whichcarries the former to be used, and thisis moved in or cut out by a screw oper-ated by the hand wheel. This gives avery delicate means of adjustment inmanipulating the work and bending to n number oi pieces can be bentexactlj alike 1«> maintaining the last po-sitii u i hand wheel. The effect of bending in this manner, by the formerfollowing up the work and exerting ateach stroke a little more pressure, isless detrimental to the material than a. Power Bender and Straightener. This machine for bending pipe, struc-tural iron, round and flat bars of variouskinds and sizes, has been developed byH. B. Underwood & Co., of Philadelphia,Pa., after considerable experience withdifferent types of mechanical appliancesin this field. It is capable, not only ofbending, but also of straightening mate-rial quickly and also efficiently. It isadapted for a large variety of work. Instead of requiring a large numberof dies or formers, it is only necessaryto have on this machine a set for the POWER PIPE KEXDER AND STRAIGHTENER. sudden bend, or trying to shape the pieceat one movement. Only a little skill isrequired to operate this machine, thereis no complication and nothing to do butmove the pipes along and turn the handwheel to suit the requirements of thework in hand.
