10 Claims.

This invention pertains to garment pressing machines and more particularly to pressing pads therefor of fibrous material of which the preferred form is metallic wool.

5 Metallic wool has been long used as padding material for pressing machines for which it is well adaptedbecause of its elasticity, non-moisture absorbent qualities and resistance to deterior-v atioh under influence of heat and moisture. Fl-

10. @0115 Padding as ordinarily used is subject to the disadvantage of displacement or skidding under pressure whereby the pads will become thin in places and afford uneven tension. This is particularly true of contoured or shaped pads of other 15 than fiat form. Various arrangements of stay wires and reinforcement stitching have been utilized with only mediocre success.

In the present invention there is contemplated a foundation form for a shaped or contoured pad 0. which while capable of being bent into the de sired configuration will be sufficiently rigid to retain its form under conditions of use and afford a supporting skeleton frame for a body of metallic wool or other fibrous material portions of which 5. are matted or intertangled with each other" through the interstices of the skeleton frame and about component parts thereof in suchmanner as to be anchored-thereto against shifting motion or skidding. S1 The object of the invention is to improve the construction as well as the function of. pressing pads whereby they will not only be economical in manufacture, but will be more efficient in use, capable .of being .contoured and shaped into agreement with'the article or portion thereof to be pressed, adapted to retain their contoured forms under various conditions of use, and unlikely to get out of repair.

A further object of the inventicn is to provide 459, a skeleton frame for a pressing pad and to apply f brous padding material thereto in such manner asto hold the padding material against displace-- ment. V

A furt; er object of the invention is to provide aform retaining reinforcement for a pressing pad which may be shaped to desired curvature and which will then maintain the prescribed shape of the'pad.

7 5p A further-object of'the invention is to provide '7 a metallic wool pad wherein the wool is securely anchored against skidding. I 1 A further object of the invention is the provision of a reinforced contoured metallic wool pad. A further object of theinvention is to provide an improved method of embedding a reinforcement structure within a metallic wool body.

A further object of the invention is the provision of a metallic wool or other fibrous pad possessing the desirable characteristics and meritor- 1;,

ions features herein mentioned,

With the above primary and other incidental objects in view, as will more fully appear in the specification, the invention consists of the fea-. tures of construction, the parts. and combinations 10 thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims. I

the drawing wherein is shown the preferred but obviously not the only form of embodiment 15 of the invention, Fig, l is a perspective view of a pressing pad embodying the present'invention, of which a portion of the padding material has been removed todisclose the embedded skeleton supporting frame. Fig. 2 is a perspective view of the 29 form retaining frame before application of the metallic wool. Fig. 3 is a detail sectional view. Fig. 4 illustrates a modification and Fig. 5 illustrates the general type of, pressing machine in which these pads are ordinarily employed. 25

Like parts are indicated by similar characters of reference throughout the several views.

In pressing garments it is quite desirable that the pads employed be contoured to agree with the portion of the garment to be pressed and 39,

special forms of pads are provided for different purposes such as collar pads cuff pads, yoke pads, shoulder pads and others. For present illustrative purposes a very simple form of contoured pad has been adopted without intent or purpose 3 5 of limiting the invention. 'It is to be understood that the invention is applicable to pressing and other pads of various shapes and sizes other than that herein shown and described. While it has been the practice to apply fine mesh screen so exteriorly to one or both sides of a body of metallic wool for confining it and to pass individual stay wires in various directions through the body of a pad, such expedients while perhaps satisfactory for some conditions of use of flat press- 45,

ing pads-are not effective for contoured pads for which the present invention is especially adapted.

It has also been found in practice that it is not sufficient to merely bend a normally fiat body of padding material into the desired shape asrthe 5'9, curvature of the body causes the material at one side to be tensioned and stretched and that at the opposite side to "be relaxed and compressed and therefore the-pad is not uniformly resilient norresponsive to pressure. To afford uniform 5 5 inner and outer sides.

In the drawing wherein is illustrated a simple arch shaped or inverted V shaped pad, the form retaining skeleton structure comprises an endless marginal frame I attached to which at their ends are transverse members 2--2 dividing the interior of the frame into multiple spaces 33 If the pad is of relatively small size as shown in the drawing, such transverse dividing members 2-2 may be extended in one direction only. However for larger pads additional dividing members 2 may be arranged in transverse direction thereby subdividing the spaces 33. Such increased number of transverse supporting members 2 in pads of larger size are preferably, although not necessarily arranged diagonally. The grid-like or reticulated supporting structure thus formed is bent and shaped into approximately the desired contour of the pad. By thus preforming the form retaining skeleton, which although capable of being bent into desired shape is sufficiently rigid to resist ordinary usage pressures,

. the fibrous padding material is uniformly distributed on opposite sides under uniform tension.

Portions of the padding material 4 are applied to each side of the contoured supporting structure under uniform tension and component portions thereof are extended through the openings 3 and are caused to become inter-matted and intertangled with each other thus uniting the portions at opposite sides of the supporting structure into a single integral fibrous body.

While metallic wool is the preferred material, due to its heat and moisture resistant character, it is to be understood that the invention is not limited to metallic wool but the padding may comprise other non-metallic fibrous material. Likewise, While especially desirable for surface contoured pad forms, the preformed grid frame on opposite sides of which the fibrous material is applied may be advantageously utilized for flat pressing and other pads which are deemed to be within the scope of the invention. Also, although metallic wool is the preferred padding material, other non-metallic fibrous material may be employed in lieu thereof.

Suitable binding 5 is preferably applied about the margins of the contoured pad. This binding may be of fabric, preferably asbestos, although it may be of other material.

For certain conditions of use it is desirable, although not essential, that the tie member 2 at the crown or top of the bent pad should be of flexible or yielding character. To this end there 7 is shown in Fig. 2, a plurality of relatively small flexible wires 6 extending between the opposite sides of the marginal frame I in lieu of amore rigid transverse member 2.

In Fig. 5 there is shown a typical pressing machine for pressing collars or yokes of garments,

and cuffs. Pads such as heretofore described are positioned upon the platens I and 8. 7

From the above description it will be apparen that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the 5 principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features, it is to 10 'be'understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
