2 Claims. (C1. 2-195) This invention relates generallyio caps, but has reference more particularly to a cap which is insulated against high temperatures A primary object of the invention is to provide a cap of the character described, which is provided with a layer of insulating material, which efiectively insulates the head of the wearer against the eflects of high temperatures, but Which does not appreciably increase the weight of the cap.

Another object of the invention is to provide a cap of the character described, in Which the heat insulating layer is permanently incorporated in the cap without means other than are conventionally employed in manufacturing the cap.

A further object of the invention is provide a cap of the character described in which aluminized cloth is employed as the insulating layer.

Other objects and advantages cf my invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of Ihis specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a perspective view of a cap embodying the invention;

Fig. 2 is an enlarged view of the cap, partly in side elevation, and partly in cross-section, taken on the line 22 of Fig. 1;

Fig. 3 is a fragmentary view, partly in elevation and partly in cross-section, taken on the line 3-3 of Fig. 1, with the shape-maintaining ring in osition, and

Fig. 4 is a fragmentary cross-sectional view, taken on the line 44 of Fig. 3.

Referring more particularly to the drawings, it will be understood that although the invention is shown and described in connection with a military cap, that it may be used in connection With conventional types of dress caps, shop caps, chauffeur caps, as well as in connectiou with hats.

The cap will be seen to comprise a cap body, generally designated by reference numeral 1, a band portion 2, which is secured -to the cap body, and a visor 3, which is secured to the band ortion 2.

The body portion consists essentially of an upper fabric portion 4 and a lower fabric portion 5. The portion 5, in accordance with conventional practice, may consist of three segments which are sewn together at their ends.

Disposed immediately below the fabric portion 4 is a layer of aluminized cloth 6, Which consists of a closely woven thin flexible fabric, the upper surface of which is provided with an extremely thin deposit or plating 7 of pure aluminum, which is flexible and has been found to have a higher degree of heat reflectivity than most aluminum paints, although the possibility of using an alnminum paint in lieu of such deposit or coating is not precluded. Such aluminized cloth is available from several sources, but has not heretofore been utilized for the purposes for which it is used in the present invention.

Disposed immediately below the cloth layer 6 is a cap lining 8, which is shown as made of a fabric having a dull upper surface, and glossy lower surface.

Disposed immediately below the lining 8 is a layer o1 film 9 of clear or translucent plastic, which has a watetproofing function and prevents the lining from becoming soiled by the head of the wearer.

The elements 4, 6, 8 and 9 are of generally circular form, and, With the exception of the element 9, are provided at their peripheral edges with inturned hems 10, 11 and 12, respectively, which are sewn, as by a line of stitching 12a, to the inturned hem 15 of the lower fabric portion 5 of the cap, so that the hemmed edges are in contiguity With each other, as at 17.

There is also provided an annular protective fabric strip 14 provided with hemmed edges to which the hemmed edges of the elements 4, 6 and 8 are sewn, as by a line of stitching 13, and to Which the hemmed edge of the portion 5 is sewn, as by a line of stitching 16.

The layer 9 of plastic is sewn, as by a line of stitching 18, the lining 8.

The cap further includes a rernovable ring-like member or grommet 19, which is disposed Within the cap, adjacent the joint 17, and which serves to 1retain or maintain the cap in circular form.

The details of construction of the band 2, visor 3, and other parts of the cap other than those described above, are more or less conventional, and need not be further described.

The aluminum coating 7 of the cloth layer 6 functions to reflect heat rays impinging upon the top of the cap, thereby preventing such rays from passing through the layers 6, 8 and 9. In this manner, the head of the wearer is not subjected to the intense heat of the sun, but is maintained fairly cool, permitting the wearer to remain fairly cornfortable for prolonged periods, even in excessively hot outside temperatures. In actual tests made under practical conditions, it has been determined that at outside temperatures cf about 114 F. the temperature directly under the cap, above the head of the wearer, is maintained at about 98 F. This, of course, represents extreme conditions, and at lower temperatures, the efficiency of cooling, produced by the aluminized cloth is even greater.

The layer of aluminized cloth is extremely light and thin, so that it does not appreciably increase the weight cf the cap, and does not, therefore, result in any discornfort to the wearer.

By securing the layer of alurninizecl cloth to the cap by the same means Which a1e conventionally employed in securing the lining in the cap, the aluminized cloth is permanently incorporated in the cap without the use of special or extraneous seouring means, so that the cost of manufacture of the cap is not appreciably increased.

Caps with such a built-in heat insulating layer are especially advantageous for use by military policemen, civil policemen, and others who conventionally wear this type cf cap.

Various modifications are contemplated as corning Within the scope of the invention. Among these are the following:

(a) The lining 8 may be reversed, so as t0 dispose the glossy surface thereof as the upper surface.

(b) The lining 8 may be eliminated, if desired, in Which case the aluminized cloth layer may function as the lining.

(c) The alurninized cloth layer 6 may be eliminated, and in l1'eu thereof, the fabric layer 4 may be provided on its lower surface With a heat reflective alurninurn coating of the character described.

(d) The layer 6 may be eliminated, and the lining 8 provided with aluminum coating.

1t is 'to be understood that the form of my invention,

heteWith shown and described, is to be taken as a. preferred exarnple of the same, and -that various other changes in the shape, size and arrangement of artsv may be. resorted to, without departing from the spi rit of my invention, er the s'eope cf the subjoined claims.

Having thus deseribed my invention, I clai'rn:

1. In a eap of the character described, a body comjprising an upper and lower portion, said upper portion Comprising a substantially circu1ar la'yer of fabric having a hem at its peripheral edge, said 1ower portion having a hemmed edge, and a substantially circular layer of a elosely woverx thin flexible fabric underlying said fabric 1ayer andhaving a hem at its peripheral edge, said 'thin flexible 1ayer having an extremely thin deposit or plating pf aluminurn on its upper surface, said h'emrned edges of the fabric layer and aluminum-coated fabric being sewn to the hemmed edge cf the 1ower portion.

2. In a cap cf the eharacter described, a body compr.ising an upper and lower portion, said upper portion .cornprising a 1ayer of fabrie having a hem at its peripheral edge, said 1ower portion having a hemmed edge, a 1ayer of closely woven (hin flexible cloth underlying said first layer and having a thin coting of aluminum 4 thereon, said second layer having a hem at its peripheral edge, said hemmed edges of the fabric layer and aluminum coated cloth being sewn to the hemmed edge of the lower portion, and a protective strip underlying said hems and sewn thereto.
