Dual heat level soldering iron

Claim 1

A MANUAL ELECTRIC TOOL COMPRISING: A HANDLE PORTION; AN ELECTRICALLY OPERATED WORK PORTION CARRIED AND SUPPORTED BY SAID HANDLE PORTION; WIRING MEANS HAVING A PAIR OF LEADS FOR CONNECTING SAID TOOL TO AN ALTERNATING CURRENT SOURCE OF ELECTRIC POWER, AND BEING CONNECTED WITH SAID ELECTRICALLY OPERATED WORK PORTION TO CARRY SAID ELECTRIC POWER TO SAID WORK PORTION; A GRAVITY ACTUATED SWITCH MEANS DISPOSED IN SAID HANDLE PORTION AND CONNECTED IN SERIES WITH ONE OF SAID PAIR OF LEADS OF SAID WIRING MEANS, SAID SWITCH MEANS HAVING A CLOSED POSITION WHEN SAID HANDLE PORTION IS HELD IN AN OPERATIVE POSITION BY A USER OF SAID TOOL SO AS TO BE AT A HIGHER LEVEL THAN SAID WORK PORTION AND AN OPEN POSITION WHEN SAID HANDLE IS AT A LOWER LEVEL THAN SAID WORK PORTION AS WHEN SAID WORK PORTION IS INOPERATIVE ON A REST RAISED ABOVE A WORK SURFACE AND SAID HANDLE PORTION RESTS UPON SAID WORK SURFACE; AND A DIODE CONNECTED IN PARALLEL WITH SAID GRAVITY ACTUATED SWITCH MEANS, SAID DIODE FORMING A CONDUCTIVE PATH FOR ONLY ONE HALF CYCLE OF SAID ALTERNATING CURRENT WHEN SAID HANDLE IS IN SAID INOPERATIVE POSITION THEREOF AND SAID DIODE BEING SHORT-CIRCUITED BY SAID GRAVITY ACTUATED SWITCH MEANS WHEN SAID HANDLE PORTION IS HELD IN SAID OPERATIVE POSITION BY SAID USER WHEREBY BOTH HALF CYCLES OF SAID ALTERNATING CURRENT ARE APPLIED TO SAID WORK PORTION, SO THAT, DURING SAID SHORT CIRCUITED OPERATION OF SAID DIODE FULL ELECTRIC POWER IS THEREBY APPLIED TO SAID WORK PORTION AND DURING SAID INOPERATIVE POSITION OF SAID TOOL WHILE SAID DIODE IS IN SERIES WITH ONE LEAD OF SAID PAIR OF LEADS, AND THE OPEN CONDITION OF SAID GRAVITY ACTUATED SWITCH PREVAILS, ONLY ONE-HALF CYCLE OF SAID ELECTRIC POWER IS APPLIED TO SAID WORK PORTION, PROTECING SAID WORK PORTION FROM EXCESSIVE ENERGY DRAIN WHEN NOT IN USE.
