GARMENT-SEAM-PRESSING IRON.

Speccaton of Letters Patent.

Patented Sept. lll, ltlllf.

Application filed April 7, 19117. Serial No. 160,486.

To all whom t may concern Be it known that l, EDWIN H. ZACHARIAS,

and useful improvements in Garment-v Seam-Pressing lrons; and I do hereby declare the following to be a-full, clear, and exact description of the same, reference being had to the accompanying ,-drawings, forming part of this speciication.

rl`his invention relates primarily to pressing irons designed for use in opening out and pressin flat the seams of garments of various kin s, particularly where the pressing operation is performed by mechanical means and the speed of operation is rapid as compared with the ordinary hand operation, although features of the invention are applicable to pressing irons generally, wherever it becomes desirable to give the goods a substantially permanent set, as in eliminating wrinkles or in setting the goods in the final formation of seams, etc.

'llhe primary object of the invention is to provide a means whereby moisture in the form of steam at a high temperature may be imposed upon the goods at a point where the goods are held in substantially the position to be nally occupied, but before the .pressure of the pressing face of the iron is applied thereto, and to control the application of the steam by the pressurev which is normally exerted in holding the iron against the surface of the goods, whereby when no pressure is exerted the application of steam to the goods is automatically arrested. Steam is applied only during the active operation of the iron, with the result that no. excess of moisture will be present at any time, and the moisture which is supplied is in such form that with practically va single pass of the pressing surface over the goods, it is entirely eliminated, and the goods left in a substantially dry condition, with the permanent set imparted thereto.

Referring to the accompanying drawings: Figure l is a plan view'of a so-called gas iron embodying the present invention, said iron being of a Aform adapted for use connection with a seam preming machine in which the iron is guided and moved by inechancal` means over the garment which has been placed on a pressing board vor support. Fig. 2 is a side elevation of the iron shown in Fig. l, with the internal chambers and passages' in dotted lines.

Fig. 3 is a transverse section, substantially in the plane indicated by the line 3-3 of Fig. l.

Fig. 4 is a detail elevation of the noseI piece of the iron, in which the discharge port for the steam and valve are located.

Fig. 5 is a detail elevation and plan of the valve with its operating device in the form of a seam opener. A

Fig. 6 is a side elevation of an electrically heated iron embodying the present improvements; and

.-Fig. 'l is a transverse section in a vertical plane at approximately the center of the iron shown in Fig. 6.

Like letters of reference in the several figures indicate the same parts.

The body A of the iron, which may be a solid or built-.up structure depending upon the particular kind of iron or the method of manufacture adopted in its production, embodies a pressing face B which will be made to conform transversely to the board or goodsv in connection with which the iron is to be used, and, as shown in Fig. 3, it is slightly concave in cross section. lhc iron is provided with heating means, which, as shown in Figs. 1,2 and 3, consists of a Bunsen burner C from which the flame is directed against the bottom of the internal face of theiron, to thereby directly heat the pressing face, and suitable vent apertures D are provided as usual for the escape of products of combustion and the supply of oxygen to maintain combustion. IThis construction conforms to any known or preferred practice and maybe varied accordingly.

The top plate of the iron body is provided with a connection through which steam may be supplied, and this connection conveniently also forms the means through which mechanical pressure is applied to the iron during the pressing operation, means for this purpose being well understood and needing no detail description. The connection, as shown, is in the form of a steam pipe plug or union l which screws into the top of the iron and from which a duct c leads Yto a. superheater duct or chamber, which, as shown in Figs. l. and 3, is inthe form of a coil or lil-shaped copper pipe e Vlocated in the heating chamber of the iron and provided with unions e2 by means of which it may be readily attached or del tached, should repairs be necessary.

charge port in or below the valve seat, as'.

shown at f in Figs. 2y and 4.

The valve G is adapted to close downwardly and may be conveniently held closed by the steam pressure, although this pressure may be supplemented by a spring H shown in Fig. 2, and when closed, it is adapted to prevent the discharge of steam through the port f. For opening the valve it is provided with an operating meanswhich conveniently takes the form of a seam opener I provided with inclined front faces 1l adapting it to enter between the portions of the fabric at the seam and to spread the seam out in a substantially flat position before the pressing face of the iron reaches the same. This valve operating member or means is preferably spaced from the front end of the pressing face a distance which will permit the discharge port f to discharge the superheated steam on the goods at a time when the goods have beenopened or laid out substantially flat, but before being reached 'lo-y the lieated pressing face of' the iron, the idea being to soften Aup the goods and to permit the steam to partly evaporate preliminary to the application ofthe pressure of the pressing face. The valve operating member normally, in the preferred construction, projects slightly below the plane of the pressing face and it is held in such position by the steam pressure or the spring F with sufficient force to prevent the valve from being opened, save at such time as pressing pressure is applied to the iron, and consequently the escape of steam or the action of the steam on the goods is prevented, except when lifted bycontact with the seam, during the pressing operation. At this time the iron is in motion and `excess heating, burning or injury to the goods is not likely,v becauseof the brief period during which the goods is subjected to the action of the steam and iron.

Obviously the invention is equally applicable to. irons adapted for being heated by any of the various well known means, such, for example, as electrically heated irons, and in Figs. 6 and 7, an iron of the electrically heated type is illustrated. In this construction; the pressing face of the iron K is 'made separate from the body L and the electric heating elements lare ocated bedscribed, so that further description of these parts is unnecessary.

ln operation, it will be understood that steam is supplied from a suitable steam boiler located at any suitable point with relation to the iron, and it is to be noted that not only is it a material advantage to supply steam to the iron, because of the advantages accruing from discharging superheated steam on the goods, but, also because of the fact that practice has demonstrated that a very considerable economy results, inasmuch as the iron may be brought to a higher temperature and maintained at a more uniform temperature, with .the use of less gas or electric current than is possible where 'water is supplied to the ,iron and steam generated in the iron by direct vaporization and consequent loss of heat which would otherwise be used in maintaining the proper temperature of the pressing face. In other words, by supplying steam to the iron, the effective heating and accurate regulation of the temperature of the pressing face may be effected which results are difficult, if not impossible;v of attainment, where water is vaporized into steam, within the liron itself.

What is claimed is 1. An iron for pressing .garment seams, embodying a body having a pressing face,

means for heating the pressing face, means for supplying steam, a discharge port for the steam located at the forward end ofthe pressing face, a valve Icontrolling the discharge of steam through said port, and means for operating said valve controlled to automatically open the valve by pressure for holding the iron down on the seam being pressed and to close said' valve when the pressure is relieved, said valve operating means being located in advance of the discharge port.
