4 Claims. (Cl. 29128) The present invention relates to ironing devices, and more specifically to rollers ffor use in ironing devices.

The ironing devices presently known to the art are generally of two types. The iirst type of ironing device uses a roller which is rotated at a uniform rate and is disposed adjacent -to an ironing shoe which may be moved into contact with the roller. The second-type of ironing device uses a plurality of rollers in contact with a larger drum, the drum being rotated at a rate slightly less than that of the rollers. ln the first type of ironing device, heat is supplied to the fabric being ironed through the shoe, the fabric being drawn between the shoe and the roller by friction between the fabric and the roller. In the second vtype of device, the fabric is drawn and stretched between the rollers and Athe drum, Iand heat is supplied lto the Ifabric through the drum.

In both types `of ironing devices there is difficulty in maintaining the cylindrical shape of the rollers. Continued use tends to bunch thematerial used in the construction ol' the roller at one end of fthe roller giving it an irregular or generally conical shape. This is partly due to the fact that the roller must present a resilient surface to the 1fabric, since many fabrics which are to be ironed contain protrusions, such yas buttons. They also compact until they have lost their resilience. A second difliculty arises from the fact that organic materials have been found to be necessary in the rollers presently used in order to provide sulicient resilience and the organic materials char because of the heat required in ironing, thus limiting the useful life of the rollers.

It is 'an object of lthe present invention to provide an ironing device which utilizes `a roller which presents a resilient suriace to the fabric to be ironed land will be substantially free from charring and compzacting.

It is also an object of the present invention to provide an ironing device with a resilient roller which will maintain its cylindrical form through extensive use.

A further object of the present invention is to provide a roller 'adapted to be used in an ironing device which neither chars nor loses its cylindrical form with extensive use.

lFurther lobjects and ladvantages of the present invention will be readily apparent to the rnan skilled in the art from a further reading of the present disclosure and claims, particularly when viewed in the light` `of the drawings, in which:

Figure l is a side elevational view of an ironing device embodying the present invention;

Figure 2 is a side elevational View of an ironing device constituting a second embodiment of the present invention;

Figure 3 is a transverse sectional view of a roller suit` able for use in both of the embodiments shown in Figures l and 2;

Figure 4 is an enlarged fragmentary sectional view of the roller shown in Figure 3 g and Figure 5 is an enlarged fragmentary sectional view of the ironing device illustrated in Figure 1 showing a fabric in the process of being ironed.

In the type if ironing device illustrated in Figure 1, a roller 10 is disposed on a shaft 12 and supported by means partially illustrated at 14. The shaft 12 and the roller 10 are free to rotate relative to the support means 14 and are supplied with rotational power by a conventional motor. An ironing shoe 16 is disposed adjacent to the roller i0 by means of conventional design partially illustrated at 18. The space between the shoe 16 and the roller 10 may be manually controlled to permit the operator to insert a fabric 20 between the roller 10 and the shoe 16, and to control .the pressure exerted by the shoe i6 and roller lll upon the fabric 20. The shoe 16 may also be supplied with a source of heat which is conventional in the `art and has not been illustrated. The three heat methods most commonly used to heat the `fabric are electrical heating, gas heating and steam heating of the shoe 16.

The roller lil is constructed with a cylinder 22 of rigid construction and the shaft 12 is disposed on the axis of the cylinder 22. The cylinder 22 is generally constructed of metal, such as iron or steel. A plurality of layers of diiierent materials 2li, 26, 28 and 30 are tightly wound about the cylinder 22 and provide the roller 10 with its resilient surface. The layer 24 is immediately adjacent to the cylinder 22 and is constructed of canvas. Immediately adjacent to the layer 24 of canvas is a layer 26 of wire cloth, such as is commonly used for house insect screens. The outer layer 3i) is cloth which may be Iasbestos "or cotton cloth. Ii cotton cloth is used as the outer layer 30, an asbestos cloth layer 28 may be inserted between the wire cloth 26 and the outer layer 30.

As will be seen from Figure 4, the layer 24 of canvas is secured to the cylinder 22 by a layer of glue 32 and overlaps the beginning of the rst turn of the adjacent layer 26, the first turn being indicated by the reference chanacter 3d. The first turn 34 of `the wire cloth of layer 26 may be cemented, or `otherwise secured, between the turns of canvas in .layer 24, thereby being prevented from rotating relative to the cylinder 22. A similar construction may be used to secure the outer layer 30 of cloth to. the last wire layer 26.

A desirable construction for the roller 10 utilizes a hollow steel cylinder with a diameter of approximately tive inches, )although other diameters are equally satisfactory. Layer 24 consists yof approximately 11/3 turns of canvas glued to the cylinder 22, layer 26 consists of approximately l0 turns of wire cloth, and outer layer 30 1consists of 2 to 3 turns of asbestos or cotton cloth.

As is illustrated in Figure 5, the roller 10 present-s a resilient surface to the cloth 20 which passes between the roller il? and the shoe 16. A button 36 is illustrated compressing the wire cloth of layer 26 of the roller 10 as it passes between the roller 10 and the shoe 16. Itis to be noted, that the layers 35) of cloth do not become substantially compressed, `and that the resiliency `of the roller 10 is supplied essentially by the wire cloth in layer 26. It is also Ito be noted that the wire cloth in layer 26 is not an organic material and will not char from continued subjugation to heat, thereby giving the roller 10 a longer life than the rollers heretofore known to the art.

The layer 3i? of cloth is longer than the length of the lcylinder 22 and overlaps the ends of the cylinder 22. A draw cord 36 is slidably disposed within a channel formed at the end of the cloth layer 30 and draws the cloth layer 30 tightly about the roller 10 in a manner conventional in the art.

Figure 2 illustrates a second embodiment of the present invention. In this type of ironing device, a drum 38 of a relatively large diameter and constructed of rigid heat conducting mateiial, such as sheet metal, is disposed adjacent to a plurality of rollers 40 of smaller diameter, us'lly three in' number. The drum 38 rotates at a rate slightly less than the rotation rate of the rollers 40. As aresult, the fabric to be ironed 42 is drawn between the rollers 4G and the drum 38. A `feeding plate 44 may be disposed adjacent to the input side of the ironing device to support the fabric-42 as it yapproaches the drum 38 and rollers 401 The' `rollers 40 are constructed identically with the rollers 10 illustratedl in the lirst embodiment of the invention, and hence the rollers 40 will not be further described. As in the rst embodiment of the invention, the rollers 40 present a resilient surface to the fabric 42 which passes between the rollers 40 and the drum 38, are constructed of material-s which will not char due to heat supplied fo the drum 38, and also will retain their cylindri-'cal shapes longer and under more severe conditions than the rollers -theretofore known to the art.

Aman skilled in the art will readily devise many modications and improvements within the scope of the invention disclosed herein, and hence it is intended that the scope of this invention be not limited by the foregoing disclosure, butv ontly by the appended claims.
