2 Claims.

This invention relates to improvements in resilient padding for the facing of ironing boards, pressing machine bucks and rolls, and for other purposes in connection with which a resilient padding material is required.

This invention has for an object to provide a novel construction of padding for the purposes stated which is characterized by a high degree of resilient conformability to various degrees of pressure exerted thereon by material supported thereby while undergoing pressing or other operations, or by reason of irregularities in the shape or surface contours of the supported material, while at the same time providing an interstitial or porous pad mass of substantial density and thus adapted to support and efficiently sustain the material being pressed in opposition to pressure applied thereto.

The invention has for another object to pro- 2 vide a novel construction of fabricated padding material of such density as is well adapted to withstand, without break down, the repeated blows and pressures to which it is normally subjected in use; while at the same time being adapt- 25 ed, by reason of the structural characteristics of the material of which it is made, to provide, in addition to the requisite resiliency as a whole, a certain degree of give and take interplay or movement between elements thereof, whereby 30 the padding will quickly, easily and snugly conform itself to protuberances on the material supported thereby, while nevertheless presenting such material smoothly spread and substantially uniformly supported subject to such'operations or effects as may be desired to be administered thereto.

To attain the above stated objects, the novel paddin according to this invention-is formed by convolved or spirally curled metallic strands of comparatively small diameter laid in contiguous parallel relation to form layers thereof, and with a multiplicity of such layers superposed one upon another until a required thickness of packing body is attained. The convolved or spirally curled metallic strand may be disposed on and along a central flexible carrier core or not, as is desired in any given case. Due to the inherent springy or elastic lateral compressibility of the convolutions or coils, as well as to interplay between the convolutions or coils of adjacent strands, there is permitted a local resilient compressibility or play at those portions of the area of the padding body which may be engaged by pretuberances on the material supported thereby 5 subject to a pressing or other action, so that said protuberances will readily and snugly imbed themselves in the padding, while otherwise the material will be smoothly supported and adequately hacked to receive the efiects of said pressing or other action.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

Illustrative embodiments of padding according to this invention are shown in the accompanying drawings, in which:

Fig. l is a fragmentary plan view of the novel padding material as applied to an ironing board, pressing machine buck, roll or other support, as the case may be, a portion of the facingcover therefor being broken away to disclose the padding mass; Fig. 2 is a transverse sectional, view of the same; and Fig. 3 is a fragmentary longitudinal side elevation and part longitudinal section, showing the application of material thereto for pressing, and also showing how a protuber ance on said latter material will imbed itself in the padding under pressure.

Fig. l is in part a side elevation and in part a longitudinal section, and Fig. 5 is a plan view with parts broken away, these views illustrating how the novel padding will accommodate itself to odd and irregular shaped bases. Fig. 6 is a view similar to Fig. 5, but showing another shape of base.

Figs. '7, 8, 9, 10 and 11 are various schematic views illustrating one method of assembling and fabricating the convolved or spirally curled strand in making up the ultimate novel padding according to this invention; and Figs. 12 and 13 are fragmentary sectional views showing various forms of stitching which may be employed to retain the assembled strands in padding forming relation.

Fig. 14 is a fragmentary view of the convolved or spirally curled strand made of round wire and provided with a central carrier core; and Fig. 15 is a similar view showing the strand made of flat or ribbon-like wire and provided with a central carrier core.

Figs. 16 and 17 are respectively fragmentary views of the convolved or spirally curled strand without a central carrier core, one being made of round wire and the other of flat or ribbon like wire.

Similar characters of reference are employed inthe above described views, to indicate corresponding parts. V

In making up the novel padding of this invention, it is preferred to employ a strand A composed of a central carrier core l upon, along' and about which is comparatively closely convolved or gimped a spirally curled metallic wire having inherent springiness, the coils of which are of small diameter to assure attainment of a pad body mass which is of substantial density and yet resilient; the metallic wire may be either of round cross-sectional shape, as the wire H (see Fig. 15), or the same may be of flat or ribbon-like form, as the wire [2 (see Fig. 15), or in fact the wire may be of any other suitable or desired cross-sectional shape. The carrier Core i0 may be made of cord, fibre, metallic wire, or other suitable but flexible material. While it is preferred to use the spirally curled metallic wire in gimped or convolved relation to a central carrier core, as above described, this is not absolutely essential, since the strand A may consist in the convolved or spirally curled wire alone, i. e. without the carrier core, as e. g. the spirally curled round wire [3 (see Fig. 16) or the spirally curled fiat or ribbon-like wire I4 (see Fig. 17), or of a spirally curled wire of other suitable cross-sectional shape.

Illustrative of one method which may be used to fabricate the strand A into a desired padding body mass, reference may be had to Figs. 9 to 11 inclusive, wherein is shown a form or frame l5 having laterally spaced legs l6. This form or frame is preferably made of heavy rigid wire or rod-like material and is of a width and length more or less in correspondence to the dimensions of padding body desired to be produced (see Fig. 7). The padding body is built up upon this form or frame I 5 by winding the strand A transversely around the same from end to end, with the turns closely placed or contiguous (see Fig. 8). When one winding from end to end of the form or frame I5 is completed, a second and subsequent end to end windings are made, thus forming superposed layers of such windings, until a desired thickness of padding body is finally attained (this is shown in Fig. 9, wherein successive outer layers thus obtained are broken away in part to disclose underlying layers).

When a body of suitable size and thickness, has thus been built up on the form or frame IS, the layers of wound strand A are engaged by means designed to hold or secure the same in their body forming relation and against unwinding, unraveling or other disintegration or displacement. One and a preferred method of attaining this end is to sew through the formed body, transversely of the windings of strands A, suitably disposed and spaced runs of stitching B, which pass through the body. The stitching may be made with a textile thread or cord, or with wire or other suitable material; and the form of the stitching may be more or less varied, two specific and illustrative forms thereof being shown respectively in Figs. 12 and 13.

After the padding body has been completed by application thereto of the holding stitching B, the form or frame 15 may be withdrawn therefrom, by sliding the legs I6 of the same outwardly from an end thereof, as e. g. in the direction of the arrow :2 applied in Fig. 10. It is not essential, however, to remove the form or frame [5, and, if desired, especially in connection with padding bodies of irregular peripheral shapes, the same may be allowed to remain in the body interior, to serve as a means for retaining the desired peripheral shape thereof.

Upon completion of the padding body, the same is mounted on a desired support H, which may be an ironing board, a pressing machine buck, a mangle roll, or such other foundation as is provided, in any given case, for the support of material to be subjected to a pressing or other desired action or treatment. Over the padding body, thus mounted, is arranged and suitably secured a facing cover E8. The facing cover I8 is usually made of a suitable textile fabric, or it may be made of other sufiiciently flexible sheet material.

In the form of the fabricated padding body described, the windings of strands A lie, both horizontally and vertically, closely contiguous one to another, so that the coils thereof will mutually bear more or less one upon another, whereby a comparatively dense pad mass, which nevertheless possesses a very lively resilient effect, is attained which variably yields to pressures applied thereto and yet quickly reacts to an expanded normal condition when pressure thereupon is relaxed, and which, as a whole, provides sufficient density to well sustain material being pressed in opposition to applied pressure. At the same time more or less mutual interplay or movement between adjacent coils may occur, especially at local areas which are subjected to pressure in excess of that applied to surrounding areas. As a consequence of the resiliency and interplay or relative movement of the coils, the padding body tends to quickly yield to and closely and snugly conform itself to protuberances which may project from material spread and supported thereon subject to a pressing action or operation. For example, a button l9 projecting from the material being pressed (see Fig. 3) will easily depress and sink into the padding body mass, so that the latter will closely and snugly conform to the button in such manner as not to interfere with but rather assure the smooth lying of the material 20 surrounding the button, especially the areas of the latter closely adjacent to the button.

While a method of fabricating the padding body has been described whereby the strands A are disposed as contiguous side by side windings arranged to form superposed layers, it will be obvious that within the broad aspects of this invention, other dispositional arrangements of the strands A and the coils thereof may be utilized.

It will also be understood that the padding body fabricated from the strands A may be made of various peripheral shapes to suit specific desires or requirements in connection with the use thereof. In Figs. 4 to 6 inclusive examples of irregular padding body shapes are shown.

It is desired to also point out that the novel padding is adapted for specific uses other than as a support for material to be subjected to a pressing action or operation. For example, the padding body is also adapted for use in furniture and like upholstery work, as well as for other purposes in connection with which a conformable and efficiently resilient padding material is required.

Since various changes could be made with respect to the finished padding and its detail make up, and many widely different embodiments of this invention could be made without departing from the scope thereof as defined in the herefollowing claims; it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

are of small diameter, disposed upon and along a central flexible carrier core, said strands being laid in contiguous side by side relation to form a layer, a multiplicity of said layers being superposed to form a yieldable pad mass of substantial thickness and density, wherein said carrier cores serve to retain spiral coils of contiguous strands against substantial relative displacement, and retaining stitching extending through the superposed layers and transversely of the'strands 10 composing the same.
