'This invention relates to pressing irons in which steam generated within the iron by electric current istransferred throunfh perforations to the material being presse The iron of this invention is constructed in such a manner that the water inlet is closed by a valve normally seated by spring tenslon which when unseated will admlt water-y through a distributor adjacent an electric 10 heating element adapted to be constantly energized, said valve preventing escape of steam around the valve stem by engagement with another seat on its upward movement.

Referring more s ecifically to the drawings, r10 designates t ebase or pressing face which is removably secured by screws 11 to Formed in the pressing face is a recess 14 which receives a pair of osses 15 projecting from the face 16 of the body portion. A 50 plurality of grooves 18 are formed in the flat held in place leso. serial no. $5,330.

faces 19 of the bosses 15 and ovcrlie rows of pcrforations 22 formed in the pressing face through which steam is emitted to the material being pressed.

Disposed between the circulaioppositely 1:.; disposed edges ofthe bosses 15 is a dis-l tributor member.\24, preferably in the form of a disk,`a portion of the bottom face of which engages the surface of the recess 14 and b a pluralityof lugs or pins 25 projecting nfyrom the face of an annular recess 26 formed in the body portion and bearing on the upper face of said distributor member.

The outside diameter of the distributor is C slightly less than the diameter of the annular recess 26 and is centered by a lug 27 formed thereon and projecting into a depression 28 in the pressing face. A plurality ot' grooves 29 are formed in the bottom face ofthe member 24 and overlie the perforations in the pressing face, the grooves in they bosses and the distributing member heilig preferably radiallydisposed and in alignment.

Wateris supplied` to the distributor member through' a pair of conduits 30, the inner endsl of which extend into `oppositely disposed openings formed in said member and is conveyed to a chamber 32 in the distributor member 24 through ports 33.' A valve 34 engages a seat 35 formed around \the upper circular edge of the distributing mjember and is provided with a stem 36 vpassing through a bore 37 in. a boss formed on the body portion. The upper end of the stem C5 is connected by apin 38 and clevis 39 to a f lever 40, vsaid valve being normally held seated by a retractile coil spring 42, the upper end of which is connected'to the lever and the lower end to an eye or the like 43 secured 90 to the'cover plate 44. Lever is pivotally connected bv a pin 45 to asuitable bracket 46 secured to the cover plate and is provided with a handle 4T preferably formed of wood or other heat insulating material. An electric heating element generally dosignated at is positioned in the body portion and Aconsists of a resistance coil 51 disposed in channels formed ina body of fire clay 'Ic or the like 52, each ,end of the coil being conmember, and a valve operating handle disnected to terminals 53 which in turn may be connected to the usual plug of a flexible wire cord extending from a suitable source of elec.- tric energy.

Cover plate 44 encloses the 'heating element and is held in place on the body member b a pair of screws 54 which also extend throng a strap 55, the free ends of which providel bales 56 for the handle 58.

Conduits 30 are disposed in parallel relation and extend through blocks 60 resting in recesses formed in the sides of the pressing face. The projecting ends of the conduits are connected to a tubey 62 detachably connected by a union 63 to a flexible cond-uit 64. The conduit 64 is adapted to be connected to a gravity feed tank or to a water faucet.

In operation the coil 51 is adapted to be constantly energized, the heat generated thereby being transmitted to the body portion and pressing face. When steam is required the operator lifts the handle (this may be easily done with the orefinger) the action of which through the lever and stem moves the valve 34 from theseat 35 into engagement with a seat 48`thcreabove formed in the face of the recess 26.

When the valve is inthis position water from the chamber 32 will ll the recess 26, then flow downwardly around the distributor into the grooves 18 and 29 wherein it will be instantly converted into steam which will then'be emitted through the perforations `22 onto the material being pressed.

From the foregoing it Will be seen that no steam can escape 'around the valve stem when it engages the seat 48 as above described, and that little or no condensation will take place due to the arrangement of the grooves and perforations therebelow.

1. An iron ot the class described comprising a pressing face having perforations therein, a body member secured to said face and an operating handle secured thereto, an electric heating element mounted in said body member, water distributing means disposed between said body member and pressing face, valve means within the body member for controlling the admission of water through said water distributing means, and a valve operating handle disposed below the first named handle, whereby the water admission valve may be operated during an ironing operation.

2. An iron of the character described comprising a pressing face having perforations therein, a body member having ooves formed in its bottoni faces overlying t e perforations in said pressing face and an operating handle secured thereto, a water distributor disposed between said body member posed below the first named handle, wherethe water admission valve may be operate during an ironing operation.

3. An'iron of the class'described comprising a pressing face having a plurality'of rows of perforations therein, a body member having a plurality of grooves formed in its face overlying the rows of perforations in said pressing face, a. water .distributor disposed v etween said pressing face-and body member,

conduits leading to saiddistributor from the exterior of the body portion adapted to be connected by iiexible conduits to a water su ply, a valve en a in a seat formed in said distributor an c osing a chamber formed therein, .said val-ve havinga steinextending through a bore formed in said bod portion, aL lever pivotally mounted on said body portion, means for connecting the valve stem to said lever, and spring means engaging said lever normally holding-said valve seated.

4. An iron of the class described comprisingv a pressing face. having a plurality of 'rows of perforations therein, a body member `having a plurality of grooves formed in its.

face overlying the rows -of perforations in said. ressing face, a water distributor disposecfbetween said pressing face and body member, conduits leadinto said distributor from the exterior of the y ed to beconnected by iexible conduits to a water supply, a valve enga ing a seat formed inlsaid distributor` and c losing a chamber formed therein, spring means" normally seatinf said valve, and means for unseating said va ve, said valve being adapted to engage-a when raised from theseat in said distributor.
