Abstract
Abstract A steam iron having a forward-pointing spray nozzle for dampening laundry being ironed provides for a substantially greater spray area to be covered by including a water-supply channel passing from a pump through the pump piston-rod to the spray nozzle which is secured to the piston rod. Manipulation of an operating button causes the spray nozzle to move up and down with the piston rod while spraying is taking place, as well as causing a valve port to be opened, closed, and scraped out simultaneously.

Claim 1
Independent Claim
203 words
In a steam iron of the type having a water reservoir in which a pump having a piston rod is disposed, bias means on said piston rod for urging said rod upwardly with respect to said pump, an operating button secured to said piston rod for vertical movement therewith, said pump being actuated in response to depression of said button and rod against the urging of said bias means, and a forward-pointing spray nozzle fed by said pump, said steam iron further comprising a steam chamber, a valve port disposed between said water reservoir and said steam chamber and a valve stem for opening and closing said valve port, the improvement comprising: a water-supply channel communicating with both said pump and said spray nozzle and passing through said piston rod, said spray nozzle being secured to said piston rod for vertical movement therewith whereby upon depression of said operating button, water is pumped through said channel and downwardly moving spray nozzle, and said valve stem also being secured to said operating button for vertical movement therewith whereby said valve port is closed upon depression of said operating button and opened in response to upward movement of said operating button by said bias means.
