The chief object of this invention is to proby welding or the like, is a cover plate 14 and duce a pressing element which may be used the cover plate,tubings and perforated pressas a head or as a buck or two elements may be ing plate form steam chambers indicated by utilized in which instance one will be the the numerals 15. Inasmuch as the. steam buck and the other the head, in'a machine of chambers are formed in the manner before 53 the character-described in the first mentioned mentioned, the amount of material is conapplication and'so arranged that it is more siderably less than that heretofore employed satisfactory to operate than the devices herein cast constructions and as a result, the tofore known and which has the further adamount of heat required to bring the presser vantages of being lighter in weight, having device up to pressing temperature is materi- 50 greater strength, and being more economical ally less than-that heretofore required. Furto produce and to operate e thermore, by reason of this construction, the The chief feature of the invention consists weight of the several parts is considerably in an accomplishment of the foregoing object less than that heretofore employed so that by constructing and arranging the parts such the operator, if the presser device is employed as that said objects are accomplished. as a head, is not unduly tired by the manual The full nature of the. invention will be manipulation of the same. vThe supply lines understood from the accompanying draW- to the heating tubes 12 and 13 are indicated ings and the description andclaims as folby the numeral 16.

Aby ing plate, the exterior tubing being indicated pass 35 discharges at 36 into the chamber by the numeral 12 and theintermediate and 30 and-the by-pass 35 communicates with the elongated longitudinally directed tubings beheader 20. As a result thereof, the moment 7 ing indicated by the numerals 13. Suitably steam is released by valve 18 to the header secured, see Fig. 2, to the top of said tubing 20, steam enters chamber 30 and engages mm inder 38 which supports a valve member 39" for sealing the opening 31 when the cylinder is expanded. The cylinder expands or elongates because it contains a fluid which when its temperature is raised increases its volume.

A diaphragm can likewise be substituted therefor, if desired. After shutting off the valve 18, the temperature in chamber 30 falls,

the volume of the fluid in container 38 is re duced and valve 39 exposes opening 31 to chamber 30 so that the steam in the chamber 15 passes through the ports 32 and 33 andthence out through the port. 31, venting the chamber 15.

Inthe Figs. 3 and 4 there is illustrated a modified form of the invention. In this form of the invention, similar parts are indicated by numerals of the one hundred series. The chief distinction in this form of the invention is that all of the steam taken from the heating tubes of valve 117 is passed by the conduit 119 to the chamber 100 and the bottom of said chamber includes the mesh or screen 123 and the absorbent material 122, which receives the condensate and breaks it up into a thin film and vaporizes'the same as previous- 1y set forth. -The dry steam passes from chamber 100 through the port 135 into the thermo-respon'sive cylinder construction 138. Chamber '130 includes the vent 131 closed by valve member 139 carried by the cylinder construction 138 and the same is normally closed at all times that steam is applied to the chamher 100-- -The header 120 includes a' discharge orifice or port 132 and when open, the header is vented to the atmosphere through chamber 130. When the heated steam is applied to chamber 100, said vent is maintained closed.

Extending from chamber 100 is a pipe 119a which communicates with the header. 120. Each header 120 includes diverging steam distributing tubes 121, which include the ports or apertures 121a therein, so that dry steam supplied through line 119 from the separator 100 is discharged into the chambers 115. The steam is vented from said chambers through the ports 121, 121a, header120, port 132, chamber 130 and-vent 131.

In Figs. 5 to 7 inclusive, a simplified form of the present invention is illustrated. This construction reduces the weight of the presser element without affecting its efiiciency. This construction in addition is more eflicient both as to time and cost of operation for the steaming chambers are reduced to a minimum volume without any appreciable reduction of steaming and pressing area.

Numerals of the two hundred series indicate like parts.- The heating passages'are 212 and 213, the supply and return thereto 216 andthe steam supply for steaming 219,-

the valve 139 is 220a and through ports 211 to the garment. This form of the invention represents a sheet metal construction.

In these figures, 10 indicates a pressing plate having the perforations 211 therein. Suitably secured to the perforated pressing plate, is a plurality of preferably square tubes, some of which 212, are peripherally arranged to conform to the outline of the presstubes, some of which 212, areperipherally arranged in spaced relation. The perforated plate port-ion between the spaced tubes is bridged by cover plate means 214, forming steaming chambers 215. 'Each cover plate portion intermediate the tubes is shown as angular.

Intermediate the ends of the presser device, there is provided a pair of end walls 200 and a cover 220-a, thereby forming separate chambers 222.- Suitably mounted or secured to thecover plate 220a, is a header 220 which communicates through the apertures 221 with each of the chambers 222 and preferably at one end thereof. The opposite end of the chamber 222 communicates through the apertures 221a with the steam chamber 215. By the aforesaid construction, therefore, a separator arrangement is provided for each of the steaming chambers, the moisture being trapped in each chamber 222 and the steam passing through the port or apertures 221a into chamber 215 for use.

Steam is supplied to the spaced tubes 213 and the peripheral tubes 212 by the lines 216 and steam is supplied to the header 220 by the line 219. As heretofore set forth, line 219 may be connected to the line 212 in a manner similar to the manner line 19 is connected to 212 at 18, see Fig. 1, or line 119 is connected to 112 at 117, see Fig. 3.
