This invention relates to pressing ma chines, and particularly to improvements in garment presses operated electrically] both as to steam generating-means vfor steaming the work, and press jaw heating means for heating the work.'A 1

An object of the invention is to produce a garment pressing machine having electrically heated press jaws as well as ilash steam generating meanswhereby the samecurrent employed to vaporize the water and produce steam is likewise employed to heat the pressing jaw surfaces. I A further object isto produce van electrically heated garment press and electrically heated high speed flash steam generating means, all of which is simple in construction rendering it possible to build pressing members or press jaws of very light weight con struction as well Vas having comparatively few parts.

The accompanying drawings illustrate the principle -and construction of a machine representative of the invention,

conversant in the art how certain changes may -be' madewithout departing from the scope of the invention.

Figure, 1 shows a sectional view through one of the pressing members looking down on top thereof showing a coiled electric resistancesteam generating member, the said view being taken on the line 1--1 lof Figule 2. i'

Figure 2 illustrates a longitudinal vertical sectional view made through the pressing jaw as along the line 2'-2 of Figure 1.

Figure 3 illustrates a cross sectional view .245 understood by vthose of the press jaw as made on the line 34-3 of Figure 2. Y Figure 4 shows .a fragmentary view of .a pressing machine with the combinedv electric heating and steam generating means 'embodied thereon.

Figure 5 shows feed end of a hollow wire electric current conductor and water transmitting member such as a German-silver tube; and Figure 6,1

but it will be4 a detailed view of an elec-v" tric connection established .with the water wire current and water transmitting -coil is shown enlarged throughout the drawings for 1the` purpose of better illustrating the invenion. Pressing machines usually comprise a'suitable frame 1Q with means for opening'and closing press Jaws; and for example, a press lever 11 is ofttimes operated by toggle o r link connections 12 which swing the press lever 11 on a frame ful'crum 13. The forward end of the press lever 11 carries ahead 14 which rises and falls in relation to a buck 15. The work to be Atreated is inserted between the pressing jaw members 14 and 15 whereupon the work .is heated, steamed and pressed by moving the head 14 downwardly vagainst the buck.

For Ithe purpose of illustrating the present invention, I have chosen the head 14 upon which a description is based outlining the embodiment of an entirely new combined steam generating means which consists in a hollow current and water transmitting wire 1,8 which is coiled within a steam sprayl chamber 19 formed in the head 14. The head 1'4 is equipped with a foraminous or perforated pressing face 20, the perfor-ations 21l of which connect ldirectly with the-steam spray chamber' 19. spray chamber 19 is lined with an insulator sheet 22-by which the hollow German silver wire -or tube 18 is positively separated and vinsulated from the pressing metal jaw 14.. The perforated press plate or face 20 is Preferably the stearn usually equipped with a fabric press cloth- 23 through which the steam discharges as it is c iected from the foraminous plate 20 onto the work supported on the buck 15.

The inner end of the hollow wire or `coiled -tubing 18 may be plugged up as indicated at 25 in Figure'6, and a lengthwise slot 26 is formed in the electrical resistance coil or wire 1.8,and the steam produced in the hollow Wireis discharged from the slot 26 into the spray chamberl9, and the steam thereafter ejects with. pronounced velocity .out-

wardly through the .foraminous plate 20 and press cloth 23 onto the work.

The other end 28 of the hollow wire 18 projects upwardly through the wall of the press jaw 14' where suitable connection is made with a water supply means as will be A described. At each extremity of the hollow wire 18 there is located binding posts 29 and rent may be turned on and oli.

30 byiwhicli'sa curreiitffeed is conf neoted in series .with the said hollow wire 18 to-A feed'current thereto.` -An electric cutoff switch32 'may bemounted on the pressV at some convenient point'by which the cur- CurrentA Hows `Afromv the current supply transmission line31 throughout thecoil or `coils-fof, hollow wire 18 raisingfthe tempera-l ture thereof-which is transmitted through in l sulatioh22to the pressing .face 20. At the salnejme -water may be fed into 'the' end -28- ofthe hollow wire which wateris generated into steam by contact with the internal' .115"

wall of the'hotwire, 'andnby the time the -water traverses the considerable-'lengthof tube', steam is'y dischargedfin'to thel spray chamber 19.'

It is to understood-- that one .vor more hollow water-and currentconducto'rs 18 may be employed depending .upon the amount of steam to be generated. The water and cui'- rent l conducting member ismade of German silver 'or 'otherf electrical resisting .material thereby producn intense heatrinfthe tube 1S when current OWS therethrough. v

" Any suitable means may be employedI vfor supplyingwater under pressure to the steam generating and electric 'transmission memer 18, andto lthis end-a water tank 34: is

mounted in fixed' relation upon the press member 11v and swings about the fulcrum center 13 during the oscillating movement of- "the 'presslever 11 which-avoids the necessityl 'of lemploying a iexible Water -joint between the water reservoir and iiash vsteam'[generat- I wing head 14. The water tank'A is equipped with 'apump -35 having a plunger 36 oper^ i ated'bya bell crank 37, and the bell ,crank (D and pull rod 38 conveniently locatedtowards the front of the machine and adaptedto be' reciprocated. by 'the operator. -A- pipe 39N 37' is manually operated' at will by afps'h connects. the pump withv Q thetank 34 'whereby the water is drawn from the tankf up intothe pump ,'35 when the plunger'36 rises by 'spring 'pressure Aor other means A ldischarge pi e 40 connects the pump withthe outer en 28 of the hollow wire current and water transmission 4tube 18,- 'A valve box '41 containing a' checkvalve` overns theV l v action vof the pump 35 whereby t e plunger I 36 ,forces .water from the. pump-35 through the pi e'40 into-the Pressing hea'dl't.v

rapidlyillingthis' chamber which causes the steam 'tof their` flow with considerable presi lsure through the perforated press face onto the work thus steam moisteningfthe garment, -raising the nap, sterilizing it, and conditioning it for -pressinganddrying- A ..It .will be notedV that the electrically heatedf-coil 18A is p laced' inside the foraminous Vspray Y chamber 19 AandA performs, among other things, three purposes, namely,* it hfeatsthe vpress face 2 0, generates-apredeltermined amount loi? steam' which is ejected into the chamber aboutv the 'c0il,' and serves` to snperheat the steainby reason of. the fact that the steamilowsin and around the eX- ternal wall'of the coil before it spraysV outwardly through the` perforations 21.

Water is periodically injected yinto the coil 18' to instantaneouslyv enerate steam at such times as steam may e required-'to condition the' cloth, but itis to be understood that the heater coil 18functions all the'time to' steam, maybe carried out.
