e in garment pressing machines and while the invention produces a press which is of general utility it is designed morevparticularly for domestic work.

Hitherto garment presses have been restricted in their use mainly to factories and tailoring shops; this primarily by reason of the fact that no adequate means is available in the home for producing steam requisite to a proper pressing action.

The main object of the present invention is to provide means whereby a liquid such as water may be transformed into steam and ejected against the pressing face of one of the pressing elements for the purpose of dampenin'g the garment to be pressed or to dampen the underlying press cloth which is forced into contact with the garment being treated.

An embodiment of the invention is shown in the annexed drawings wherein Figure'l is a sectional elevation of the head and buck elements ofa press,

Figure 2 al longitudinal sectional view. of the head with parts broken away,

Figure 3 a detail sectional view showing the water measuring chamber,two" of the control valves and the conduits leading tothe yspray producing structure,

, Figure 4 a top plan view 'of the head with the cover plate removed, and

Figure 5 a longitudinal vertical section of the head. f Y p In the drawin s 1 denotes a buck which maybe heated as y any suitable means (not shown) and 2 the pressingfface of the head. The head will, of course, y:be mounted upon vsuitable mechanism for movement toward and from the buckbut'- as such arrangement has nothing to do with the present Iinvention it is not shown. v

The pressing face 2 of the head is formed of metal and has imposed thereon, and held in close relation thereto, suitable electrical.

heating elements 3 of anyl approved form. A flexible cable 4 extends therefrom.`

The member 2 is provided, adjacent its center and extending longitudinally thereof, with a pair of upstanding ribs 5 and 6 spaced from each other and forming with an overlying plate 7, which is secured to the member 2, a longitudinally extending chamber 8. Said member 7 also holds the lnner runs ofthe heating element 3 in position and in close contact with the ribs 5 and 6 so that the chamber 8 is maintained in al highly heated condition at all times.

A suitable sheet or plate 9, as asbestos, overlies the outer runs of the heating element 3 and overlies the plate 7, being held in position by a plate 10, which latter is secured in place by screws 11.

A cover plate-12 extends over the entire head except the under pressing face 2 and a filler 13 of asbestosor the like underlies lhe cover plate and prevents radiation of eat.

The plate or member 10 is provided with a centrally disposed hub 14 through which ex- .orations 18 'throughout its length. Said pipes 17, as will he seen, lie within the chamber 5 and consequently the pipe becomes heated by reason of the fact that the surrounding met-al portion of the head is heated as above specified.

A slot 19 extends throughout the length of the chamber below the T 16 and the tubes 17, opening outwardly through the pressing face 2.a'nd directly above a baille plate 2f). Said plate is formed of relatively lexiblenons corrosive metal and is designed, when'the head is lowered into pressing position, to be forced upwardly into ya recess 2l standing directly above the plate in the' pressing face 2.

The upper end of the pipe 15 is connected into a T 22the lateral branch of which is connected with a pipe 23 which in turn is To the upper end of the T 22 there is secured a short tubular section 27 to which in turn is secured a valve 28. Said val've is in communication with a water receiving and measuring chamber 29, water being delivered thereto through a valve 30 interconnected with a conduit 31 preferably formed of fiexible material to allow for movement of the head with reference to the buck.

The water chamber 29 adjacent its upper end is connected with the air linev through a' check-valve 32 extending into the horizontal member of the T 24. The valve seats outwardly of the water chamber and thus prevents outfiow of water therefrom while permitting air underV pressure to flow inwardly when the valve 25 is open.

Mounted in the upper end of theitting 27 is plug or bushing 33 threaded into which is a tube or pipe 34 of relatively small diameter, said t'ibe extendingdownwardly` through the T 22 and the pipe 15. At its lower end, it is provided with lateral branches or nozzles 35 and 36 which terminate within the tubes 17 .l

The under face of the pressing element2 will.V preferably beplanished and for certainv valves 25 and 28, valve 30 being closed, and -air under pressure passing from the line 26 will force the water from the chamber- 29 downwardly through the tube 34 and through the nozzles or laterals 35 and 36. At the same time air rwill pass downwardly through the pizpe 23, pipe 15 and into the perforate tubes v.'Ihepipe 17 being heated and the chamber 8 likewise being hot the water which is in atomized or semi-atomizedl condition will be convertedl into steam and will be forced outwardly throughthe slot 19 into contact with the underlying baflie 20 and thus spread outwardly over the entire pressing surface of the member 2. v p

If the head is held close to the garment the garment will be dampened'or if the press .cloth is employed said cloth will be dampened and' may be brought into contact with the underlying garment on the buck. The head 'is then depressed and being hot will effect the proper operation through the damp pressing cloth or cover or will effect the roper 'pressing operation of the dampene garment if the cloth is absent.

When the pressing has been effected air alone may be admitted to the chamber 8 and blown outwardly onto the pressed garment or through the press cloth onto the garment. Such air will of course act to remove moisture from the garment, if any be present, :rnd inasmuch as the air becomes heated in itspassage through chamber 8 its drying action is enhanced.

In a garment pressing machine the lcombination v of cooperative pressing element-s; one of which at least as provided with a chamber having an opening terminating directly at the outer pressing face of such elcment substantially coextensive with the length thereof; means for heating the walls of said chamber; and means for spraying a liquid into the chamber.
