WOVEN-WIRE-CLOTH COVERING FOR PRESSINd-MACHINE ELEMENTS.

Application filed October 5, 1926. Serial No. 139,732.

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

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

In describing this invention. reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

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.

Fi re 4 is an-inner face View of the sheeting covering the face of the press head and showing the steam deflector.

Figure 5 is a cross sectional view similar to Figure 3 showing my invention applied to a head having a fiat pressing face.

It will be understood by those skilled in the art, that the pressing elements or platens of pressing machines are formed hollowoand heated by steam supplied under relatively high pressure from a boiler, the steam in some instances being ejected from a central chamber in the pressing element through jet openings in the ironing face. The steam ejected at a relatively high pressure is also necessarily extremely hot and oftentimes hot enough to scorch, burn or injure thegarment, and also the pressing element heated by the steam is sometimes so hot as to scorch the garment, while it is only necessary that the steam ejected in the garment be moist in order to dampen the garment during the pressing operation.

By my invention, the steam applied at relatively high pressure is spread out and its force'and temperature reduced so that the steam merely carries enough moisture to dampen the garment without scorching it andalso by my invention, the head or iron.-

ing face is at the same time by thesame" the sheet 11' is coextensive only with the, pormeans prevented fromscorching or-burning the garment.

This invention comprises generally, a flexible metallic covering for the pressing-face 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 pressing face and being compressible against the face of a pressing element as the garment is pressed between them.

I have here shown my invention as applied to a standard'type of platen press including a head 1 movable toward and from the buck 2 carried by a. suitable frame 3,.

the head 1 being carried .by a yoke or'lever 4. of any well known construction, which yoke 01' lever is actuated in any well known manner. Both pressing elements are usually formed hollow for receiving a heating medium as steam.

My invention is here shown as applied to the head 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 6 having jet openings 7 to the ironing face of the head. Steam is supplied to 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 known manner. Also air is oftentimes projected through the jet openings, the air being usually heated.

The flexible metallic means covering the pressing face of the head 1, as here shown, 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 thehead loose enough to allow the ortion thereof over the ironing surface of t e 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 fiexible means also usually includes a second layer of wire mesh cloth 11' underlying'the layer 9 or the portion onl there of opposed to the ironing face of t e head 1, that is, the sheet 11 is coextensive with the ironing face and is unsecured. at its marginto the head 1. .The sheet 11 has no margins secured to the head and, therefore,

tion 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 it). The openings of the sheet 11 opposite the jet openings 7 are either tilled up with lead orsolder or are covered by a strip of metal 12. this strip 12 acting as a deflector. The layers!) and ll act as a distributor for the steam or other tluid as air.

By reason of these layers of wire cloth between the garment and the heated pressing surface of the head. there is no liability of scorching the garment and further the heat is radiated through this grid or wire cloth. no shine or gloss :ppearanee can be left on the garment after the completion ol the pressing operation.

What I claim is:

1. in a pressing machine. the combination of upper and lower pressing elements. one ol which is movable toward and from the other and one being termed hollow l'or receiving a heating medium and provided with a line oi jet openings through its pressing face for ejecting tluid and a metallic flexible sheet e j rerin; the pressing face of said element and spaced apart there from and formed with pert". ations throughout the greater part of the area thereof covering the pressing face forming a distributing chamber for the fluid ejected through said jet openings and said sheet having means in line with said jet openings for deflecting the fluid later all}; through said chamber.

In a pressing machine. the combination of upper and lower pre. fng platen elements, the upper being movable toward and from the lower. the upper pressing element having perforationsextending along its medial line through which tluid is ejected and a double layer of fine wire mesh cloth overlying the pressing face of the upper element, the outer layer being, secured at its margins to the margin ot the upper pessing element and being normally spaced a ing lace and eoinpressilue against the ironing face of the upper element. as the upper element. reacts with the lower element to press an article thereon and the inner layer being substantially coextensive with the ironing face ot the upper element and unsecured at its nntrgins.

In testin'ioin where t, l have hereunto signed in name, at Syracuse. in the county of Onondaga, and State jew York, this 25th da oi September, 1926.
