The forward leg 32 of the handle member 38 is hollow and provides a recess 34 which registers approximately with an opening 38 in the upper surface of the reservoir 22. A tube 38 having an upper flare 4G is firmly sealed to the rim of the opening 36 and acts on an upwardly projecting filling funnel therefor.. The tube 38 projects upwardly above the upper surface of the reservoir 22 and into the recess 34 of the handle. ably the flare 48 is formed after the leg 32 of Preferhandle is placed over the tube 38, as by spinl ning or swaging, and serves as means to x the handle to the reservoir at the forward end. The construction shown in Fig. 1 with the 'main portion of forward leg 32 of handle. 38 spaced outwardly from tube 38 is also preferred since a minimum of surface contact is permitted in order that heat transfer to the handle shall not be eX- cessive.
A valve orseal 42 consists of av disc-shaped member provided with a resilient sealing ring 44 of rubber-like material, and the same is capable of engaging in the flare 48 to close and seal the upper end of the tube 38. A central, upwardly extending stem 48 on the valve 42 passes slidably through a central aperture in a spider 48 firmly mounted in the recess 34 above the upper end of the tube 38. The spider includes apertures 50 to permit passage of water therethrough. A compression spring 52 surrounds the stem 46 between the spider 48 and valve 42 and urges the valve into sealing position in the flare 4l), tightly closing the upper end of tube 38.
Means is also provided for lifting the valve 42 away from the flare 48 against the force of spring 52 and includes a lever 54 pivotally mounted midway of its length in a slot 56 formed in the grip portion 58 of handle member 30, by means of a pin 68. One end of the lever 54 has a pin-andslot connection 82 with the upper end of valve stem 48, and the other Aend 64 thereof projects upwardly out of the groove 58, to act as a cam follower. A portionof the grip 58 of handle member 38 is not integrally formed with the rest of the grip and is slidably mounted with respect thereto for movement along the handle. This grip portion forms Ia combined closure for the upper end of recess 34, a manual operating mem-v ber for raising valve 42 by means of lever 54, and is designated by reference character 85. Any suitable slidable mounting which retains the slidable grip section 68 in place on the handle will serve the purpose, but a preferred form of connection is shown in the drawings wherein slotted plates 88 are firmly embedded in the main grip section 58 and are received in grooves 'I8 in the slidable grip section 88, while a cross pin 'l2 carried by grip section 85 passes through the slots in the plates to retain the parts in place and provide limiting stops for the sliding movement. The undersurface of slidable grip section 86 is provided With a cam surface I4, 78 which, by cooperating with the projecting end 84 of lever' 54 rst lifts the valve'42 and then retains the same lifted as the grip section is moved rearwardly, or towards theright, as shown in the drawing, or permits the` valve 42 torloweragainst the flare 40 as the grip section B8 is moved all the way forward, or to the left in the drawing.
A spring urged latch 'I8 automatically engages in a notch 8v!! to prevent movement of the grip section 68 after it hasl been moved forwardly all 4 to move the grip rearwardly it is then necessary to press a release button 82 which is exposed at the upper surface of the grip section 88 in a sha1- low recess 84, and which is operatively engaged with the latch 18 to release the same.
Threadedly mounted in an opening in the plate i8 and in another opening in the proximate bottom wall of the reservoir 22 is the lower end of a standpipe `88. YClamped between these two walls by means of said threaded connection is :preferably provided a sealing member or gasket 88 which prevents any leakage of moisture around the outer surface of pipe 86 between the reservoir 22 and steam chamber I8. The standpipe 86 Vprojectsupwardly through the opening 36 and above the top surface of the reservoir 22 into the Ypipe 86 is closed off, preferably by pinching or crimping, so as to prevent accidental ingress of moisture to steam chamber I8 during filling, and has side openings S8 at its upper end to form steam passages connecting the upper portion of the tube 38 with the chamber I8 and with jets 20.
The forward wall of the forward leg 32 of the handle member 38 has a vent or relief opening 92 which communicates with the recess 34 between the valve 42 and the closure portion of slidable grip section 88 for a purpose which will hereinafter appear.
In operation, assuming the iron to be in the condition illustrated in Fig. 1, and without water, the button 82 is depressed to release latch '18, and grip section 88 is slid rearwardly by the thumb of the same hand which grasps the handle 38, uncovering the upper end of recess 34 in the for ward leg 32 of the handle. This rearward movement of the grip section also simultaneously raises and holds valve 42 away from flare 48 by the impingement of cam surfaces 14, '1S upon. the upper endk 64 ofthe lever 54. The iron is then ready for filling `and has been brought tov that condition by movements which can be conducted entirely by the hand which engages the grip portion 58 of handle 38. In the meantime the other hand of the operator may be engaged in filling the iron with the desired quantity of water.
-vThe water is introduced through the upper end ofrecess 34, passes through openings 5G in spider 48. between the raised valve 42 and the flare 48, through tube 38 and into the reservoir 22. The water first engages the baille 28 and runs from the lateral edges thereof (not shown) into the lower portions of the rreservoir 22. Since the upper end of standpipe 86 is closed as shown by reference character 88, and since the openings Bil are in the sides thereof, the danger of introducing water into the standpipe during lling is removed. 1
When filling of the iron is completed, the thumb of the hand which grasps the grip portion 58. is moved forward to slide the grip section 66 forward. As the end 84 of lever 54 leaves the flat section' I8 of the cam surface, valve 42 is no longer-retained in open position. Further movement forward permits the end 64 of lever 54 to travel upward along the sloping cam face 'I4 and nallyfvalve 42 closes tightly against flare 40 under the influence of spring 52. At the same time, the grip section 88 moves forward until it closes the upper end of recess 34 to prevent inadvertent dropping of any foreign mattei' into the filling system while the iron is in use or stored,`
and `until the iron is ready for emptying or for the way into grip completing position- -In order anotherrelling. As the grip section 66 moves to-flnal closing position, thelatch 18f snapsinto the recesse to retain the grip section in forward position.
Passage of electricl current through the element Illin the. conventional manner causes the soley plate I2 to heat up and thusraises theY temperature of the-water in reservoir 22. When the temperature becomessuiiciently high, steam is driven oi from the upper surfaceofzthewater, passes aroundl thev baffles 24,; 26 and- 28, up into the tube` 38; through openings 90 into the standpipe-'86y and downwardly VintoI steam chamber Il;v
from whencerit isl ejected byjets 2li onto the materialbeing ironed. FromV thisit can be seen that, with the valve42 closing its upper end; the filling tube138-1becomes a steam dome cooperating with' thestandpipe 86fito `provide a trap which prevents water droplets from reachingitheesteam ,jets 20'.;
In `case-anyof; the steam passages, such. as jets;V 20, should somehow become clogged, and cause arise of pressureto occurgin the reservoir 22; vthe' invention also serves the purpose of a relief'orisafety valve. Whenfthe steam ,pressure becomes sumcient to overcome: the force of spring 52, the valve 42 raises-slightly andrelieves thev pressure, allowing the steamv to escape through exhaust opening or vent 92. Thisopenvf ing.v is located in the front portion; of the front` leg 32 of handle 30y so as to ber directed gene erallyawayfrom the operator at all times to avoid the possibility of injury or discomfort. Theforward location ofthe opening 9,2 is also such that4 a slight cloud of. condensing lsteam issuing therefrom will quicklyA catch the eye of the operator and give prompt warning of the improper functioning oftheiron.
From the foregoing` description it can be seen that .the invention provides aneconoinical structure for a steam iron which combines the functions .of a .steam domel orfwater trap, a filling mechanism, and a relief valve. Furthermore, the parts are conveniently arranged at the forward part of the iron so that filling canL takeplace conveniently through .the forward upper part of theV handle, and the relief valve exhaust can be.
forwardly directed ina conspicuous, yet harmless direction.
Furthermore a novel handle is providedsucn thata section, Sethereof is slidable to two positions.. In the rst position the section completes a, smoothly contoured comfortable. handle suitable for ironing,.,and at the same time closesthefilling system of the iron to prevent access of foreign matter thereto. In the second position it vopens thevfilling system for the introduction of water. In addition the slidable portion of the handle is interconnected with va steam dome closure valve soas to open and close the same automatically in response to sliding of the handle section. The slidable section 5B ofi-the handle is so located as to be vconveniently operthroughv and 'havingfan open'itop; theothe'r1end of the passage. communicating; with@ said reser-.
