This invention relates to pressing machines of the platen, type used in laundries and tailor shops and clothing manufacturing and hasfor its object a particularly simple and efiicient means for distributing high pressure steam over the garment or other article being pressed and protecting such arment against scorching and a ainst the formation of a shiny or glossy sur ace.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

n In describing this invention, reference is V Figure. 1 is an elevation, partly broken away and parts being omitted, of a pressing machine embodying my invention.

Figure 2 is a longitudinal sectional view through the press head.

Figure 3 is a cross sectional view.

Figure 4 is an inner face view of the sheetingcovering the face of-the press head and showing the steam deflector. I

Fi re 5 is a cross sectional view similar t6 Figure 3 showing my invention applied to,a head having a flat pressing .face.

- Figure 6 is a view similar to Figure 4 e2 I-. cept that the steam deflector shown .in this. .view is formed in the woven-wire cloth or sheeting itself by filling'the interstices of the sheeting, throughout a section of its area, with lead or solder. v

Figure 7 is an enlarged cross-sectional view of a piece of solder-filled woven-wirecloth" or sheeting like that shown in Figure 6. q

It will be understood b those skilled in the art, that the pressing e ements or platens of pressing machines are formed hollow and heated by steam supplied under relatively high pressure from a boiler, the steam m some instances being ejected from a central chamber in the pressing element through jet 0 enings in the ironin face. The steam e ected at a relatively high pressure is also necessarily extremely hot and often times hot enough to scorch, burn or injure the garment, and also the pressing element heated dated August 16, 1927, Serial No. 139,782, filed October 5 1926. Application for reissue filed October 15, 1930, Serial NoLBSQMH in order to dampen the garment during the pressingioperation.

By my invention, the steam a plied at'relatively high pressure is s rea out and its force and temperature 1' uced so that the steam merely carries enough moisture to dampen'thegarment without scorching it and also by my invention, the head or ironmg face is at the same time by the same means prevented from scorching or burning the garment. i

This invention comprises nerally, a flexible metallic covering for th of one of the pressing elements of the machine, usually the head, said covering. being normally spaced apart from the pressing face and formed with openings therethrough throughout the'area of the pressin face and being compressible against the ace of a pressing element-as the garment is pressed between them; 1

T have here shown my invention as applied to'a standard type of platen press in cluding a head 1 movable toward and from the buck 2 caried b a suitable frame 3, the head 1 being carrie by a yoke or levers of any well known construction, which yoke orlever is-actuated in any well known manner. Both pressing elements are usually formed hollow for receiving a heating medium, such as steam.

M invention is here shown as applied to the ead 1 which is formed with'a heating chamber 5 and with a lengthwise channel or chamber 6 extending lengthwise" and centrally thereof and within the chamber 5, the chamber (Shaving jet openings 7 to the irone pressing face ing face of the head. Steam is supplied to I the chamber 5 in any well known manner and also to the chamber 6 as through a pipe 8. The flow of steam through the chamber 6 and jet openings 7 is controlled in any-well comprises a layer of fine wire mesh cloth 9 of some non-corrosive metal, the margins of this cloth being secured'at 10 to the edge of the head 1 around the same. It is also secured to the head loose enough to allow the portion thereof-over the ironing surface of the head to sag away approximately one quarter of an inch when the head 1 is not in contact with the garment on-the buck 2. This flexible means also usually includes a second layer of wire mesh cloth 11 underlying the layer 9 or the ortion only thereof opposed to the ironing ace of the head 1, that is, the sheet 11 is coextensive Withthe ironing face and is unsecured at its margin to the head 1. The sheet 11 has no margins secured to the head and, therefore, the sheet 11is coextensive only with the portion of the sheet 9 extending over the ironing face and is not coextensive with the entire sheet 9 including its margins, which are folded around the edges of the head 1 and secured thereto at 10. The openings of the sheet 11 opposite the jet openings? are either filled up with lead or solder or are covered by a strip of metal 12, this strip 12 acting as a deflector. The layers 9 and 11 act as a distributor for the steam or other fluid as air.-. Y j

In'Figures 6 and 7 I show a deflector 13 formed or constructed integral with the woven-wire-cloth or sheeting 11 by filling the interstices dfthe sheetingthroughout a section of its area opposite the line of jet openings 7 with lead or solder. In this manner I am able to construct a woven-wire-cloth or sheeting having a deflector for the purposes above described which at every point is the same thickness because the thickness of the lead or solder filled portion need not be greater than the thickness of the wire-cloth itself, see Figure 7.

By reason of these la ers of wire cloth between the garment an the heated pressing surface of the head, there is no liability of scorching the garment and'further as the heat is radiated through this grid or wire. cloth, no shine or glossy appearance can be left on the garment after the completion of the pressing operation.

What is claimed is:

1. In a pressing machine, the combination of upper and lower pressing elements, one of which is movable toward and from the other and one being formed hollow for receiving a heating medium and provided with a line of jet openings through its pressing face .for ejecting fluid, a metallic flexible sheet covering the pressing face of said element and spaced apart therefrom and formed with perforations throughout the greater art of the area thereof covering the pressjet openings for deflecting thefluid laterally through said chamber.

2. In a pressing machine, the combination of upper and lower pressing platen elements,

upper element as the upper element coacts with the lower element to press an article thereon and the inner layer bein substantially coextensive withthe ironing face of the upper element and unsecured at its margins.

3. In a pressing machine, the combination of upper and lower pressing e'lements, one of which is movable toward and from the other and one being formed hollow for receiving a heating medium and provided with J a line of jet openings through its pressing face for ejecting fluid, a metallic flexible sheet covering the. pressingfaceof said element and spaced apart therefrom and formed with perforations throughout the greater part of the area thereof covering the pressing face formin a distributing chamber for the fluid ejected through said jet openings and said-sheet having a deflector formed therein by filling the interstices thereof throughout a section of its area opposite the line of jetopenings .with solder for deflectingthe fluid laterally through said chamben 4. A pressing machine comprising a pair of coactmg press aws, one of said aws being hollow and adapted to be heated by means of a fluid heating medium conducted to and discharged therein, and comprising a row of jet openings leadin from the hollow portion of said jaw to t e pressing face thereof through which said fluid is adapted to escape, in combination with a woven-wire-cloth covering the pressing face of said jaw, anda deflector in line with said jet openings, said deflector being formed in said-wire-cloth by filling with solder interstices throughout a section of its area opposite said jet openings.

In testimony whereof I afiix my signature.
