Another object of this invention is to provide ssuoii an automatically controlled iron, in wiiie automatic feature may be eliminateri F (i the iron heated mntinuousiy.

The ends of the strip forming the heating element 2 may be brought out at the rear of the iron Shown at i and to form terminals for con eating the heating element 52 to the air- ("llt.

With the arm 23 in this position, the frame 17 will be held in depressed position and the contacts 8 and 9 will be held closed sothat the circuit through theheating element 2 will be maintained so long as the latch 23 is maintained in position,

It will thus be seen that as long as the iron is in operatiomjshe circuit heating element2 will be closed by depression of the grip 18 so as to close the contaste 8 and 9. Heat will, therefore, be
