4 Claims.

This invention relates to improvements in pads and covers for steam ironers, pressing machines and mangles, and more particularly to the construction and utilization of a unitary cushion-type pad, composed of various layers of diverse materials. The principal object of this invention is to prolong the period of use of the pad and to increase and facilitate the pressing of clothes lwith a presser, employing sucha pad.

Another object of this invention is to provide a pad for a conventional steam press, suchas is employed in commercial dry cleaning plants, which will enable garments to be pressed by the steam and not by pressure thereby resulting in a high nap finish on the garment. f

Another object of this invention is to provide an inexpensive and economical soft cushiontype pad, composed of a number of layers of diverse material, which will facilltate and render more convenient the task' of pressing since it will allow an average presser to press with a soft touch and will allow the steam to permeate through the pad and to contact the article of clothing being pressed.

A meritorious feature of this invention resides in the provision of a unitary pad composed of an asbestos layer, a fiber glass layer, and a sponge rubber layer, all joined permanently together by adhesive means so as to form a unitary laminated pad.

These and ancillary objects and other meritorious features are attaine'd by this invention, a preferred embodiment of which is described in the following specification and is shown, .by way of example only, in the accompanying drawings, wherein:

Figure 1 is a perspective view of the laundry ironing press, showing the pad constructed according to the principles of this invention, covering the pressing platen and broken away, in order to show the various Sections forming the unitary pad;

Figure 2 is a transverse sectional view, taken substantially on the plane of line 2-.-2 of Figure 1, and;

Figure 3 is an enlarged fragmentary view, showing the various components of the pad .in broken-away Sections.

This invention relates to a unitary pad, which is adapted for employment as a covering pad on a steam press, used in commercial laundries or cleaners, the press being particularly of the jaw motion type. which has coactlng jaws openstationary jaw or buck and the top head convey the steam to the work, the buck being conventionally covered by a cover, which is composed of various fabrics. However, the conventional covers have a tendency to either rot or smolder and must be replaced at short intervals. Further, the pads tend to pack down and are not able to effectively present an even distribution of steam to the clothes due to the absorption of moisture by the pad. This causes a shine to be imparted to the garment and shortens the life of the garment.

It is the primary aim of this invention to provide a novelly constructed pad, which will re" main porous and will not become packed down and which will give an even distribution of steam, thereby enabling a garment to be pressed by steam and thereby imparting a high finish to the garment. i

-A conventional ironing press is generally denoted by the character reference IO and includesv estal 20 which is seated on the floor or other suitable support. The buck is adapted to convey steam to a steam connecting pipe 24 and the head is formed with a chamber formed with a grid plate 44 on which is disposed a porous cover 42, such as muslin or the like and through which is conveyed steam, the steam being conveyed to the head by a conduit 46.

The buck is conventionally formed of metal and has an upper wall or grid 26, which has a series of perforations or apertures 30 formed therein for allowing the steam to pass upwardly to the work supported thereon.

This invention relates to a unitary pad, which is adapted to be placed or secured on the buck and which comprises an asbestos sheet or layer 28 of a suitable contour so as to fit the elliptical contour or shape of the buck. 'I'he asbestos layer 28 is merely placed or laid on the grid of the buck 12, so as to cover the apertures 30 formed in the upper wall thereof.

Sultably secured to the upper surface of the asbestos section, as by adhesive or the like, and

,supported thereon is. a section of glass, such as fiber glass, which may be woven or spun and is ing and closing on the clothes or work. The of asuitable helght and equal thickness throughaasaeia out. The glass insulating layer, which is porous, supports a multi-cellular layer of rubber material such as a Sponge or foam rubber layer, the latter being secured on the upper face of the glass layer by adhesive or glue of a suitable type so as to withstand the heat.

suitable means are provided to secure the pad 35 to the buck and may include -a sheet or covering of suitable fabric material such as muslin or the like 38, which is wrapped around the pad and has its ends 40 in'turned and secured to the bottom of 'the buck by riveting or adhesive or the like.

The pad is thus adapted for disposition. upon the buck, into which and through which steam would -be admitted by means of the conduit means associated therewith. Thus, steam passes through the head and covering and through the lower buck and pad and is brought into contact with the garment l-aid on the pad.

The press, thus, does not press the garment by pressure but by steam passing through the upper headed buck. Of course, the head of the machine never stays closed for more than five seconds in any one pressing lay. The operator will shoot the steam through the bottom buck and through the pad onto the garment. After this part of the pressing operation the operator would then depress his vacuum valve (not shown) conventionally associated with the machine, Whereby the pad would be cooled below room'temperature due to the latent heat of evaporation of the Water.

As the buck is at 320 F., it is too hot to restthe unprotected rubber portion of the sponge pad thereon. The .asbestos cloth, therefore, on the bottom of the pad is employed to protect the fiber glass insulating pad from abrasive action caused by the movement of the air on the pad when it is in operation upon the press and -also as an added insulation for the Sponge or foam rubber top layer. Of course, ;the intermediate layer of flber glass is the main insulating layer or member for the rubbersection and protects the same from 'the intense heat of the buck.

It is felt that the unitary laminated pad, illustrated and above described, will allow rthe average presser to press with a soft touch, whereby a minimum pressure is employed and the garment is pressed by the steam applied upon the garment, resuiting in a high nap finish on the g-arment closely approaching the finish of the .material when it was new.

Of course, since various other embodimen'ts may be practiced, limitation is sought only in accordance with the terms of the appended claims.

Having described the invention what is claimed as new is:

l. A umtary laminated pad for a steam heated pressing buck comprising an asbestos bottom layer adapted for disposition on the upper face of the buck, a glass insulating layer superimposed on the asbestos layer and joined permanently thereto. a top sponge rubber layer secured on the glass insulating layer and means to secure the pad on the bucl-r.

2. A unitary laminated pad for a heated pressing platen comprising an asbestos sheet adapted for disposition on the upper face of a platen, a fiber glass insulating layer permanently superimposed on and secured to the upper face of the asbestos sheet, a Sponge rubber layer seated securely on and secured to the upper face of the glass insulating layer, said asbestos shee't and superimposed l-ayers being similarly congured.

3. For use with a pressing platen, a unitary laminated pressing pad including an asbestos sheet adapted for disposition on the upper face of the platen, a fiber glass insulating layer superimposed on and permanently secured to the asbestos sheet, a Sponge rubber layer of substanitial and even thickness superimposed on the flber glass insulatlng layer and permanently secured xthereto said sponge rubber layer being thicker than the insulating layer and a fabric member embracing said pad and engaged on the upper face of the resilient layer, said fabric member being secured at its opposing free ends to the under side of the plate whereby the pad is retained on the platen.

4. A unitary iaminated press pad for a pressing platen comprising an asbestos bottom layer adapted for disposition on the upper face of the platen, a porous glass insulating layer superimposed on and joined to the asbestos layer and a multi-oellular rubber material secured on the upper face of the glass insulating layer and adapted to receive and support articles to be pressed.
