881 CONSTRUCTION Filed Jan. 25. 19-41 I4- is BY I ATTORNEY Patented Mar. 9, 1943 HAT CONSTRUCTION Ernest J. King, New York, N. Y. Application January 25, 1941, Serial No. 375,876
My invention relates to sweat-bands for hats and is more particularly directed to auxiliary means and a method of connecting an ordinarysweat-band to a hat so as to prevent the perspiration from reaching and staining the body of the hat and its ornamental hatband.
It is well recognized that the obvious expedient of disposing a waterproof member between the sweat-band and the body of the hat does not provide the solution because the connecting threads act as wicks and the needle holes likewise permit the moisture to reach the body of the hat therethrough.
It is therefore the principal object of the present invention to provide a. construction whereby such thread and needle holes are so disposed and so treated as to effectively prevent the undesir- I able travel of the perspiration in the manner described.
' Another object of the present invention is not only to insulate the body of the hat from the Fig. 2 is a fragmentary view thereof with the sweat-band lowered to illustrate the construction thereof.
Fig. 3 is an enlarged view similar to Fig. l.
The hat H, provided with a brim B, has the usual leather sweat-band l3 therein and the means adopted to positively insulate the hat body from the sweat-band comprises in general the special waterproof liner L folded to provide the sides and II, the line F indicating the fold-line.
To render effective the treatment hereinafter described, the inner L consists of a thin. highly flexible sheet of a thermoplastic synthetic resin, such as cellulose nitrate, cellulose acetate and vinyl resins, which class of resins is inherently thermoplastic and unlike the thermosetting class, can be caused to flow by the application of heat and pressure or suitable solvents without causing a chemical reaction. v
The sweat-band is assembled by stitching the side ll of the liner 1. to the bottom edge of the sweat-band i3 by a line of stitching l4 and stitching the side I!) of the liner L to the hat by a line of stitching I 2.
The stitch holes and threads are then most effectively sealed against the transmission of perspiration by the procedure of applying a solvent of the thermoplastic liner L to these lines of stitching, thereby coating the threads to prevent any capillary or wick action and virtually making the liner and threads integral.
This end may be realized by means of either a solvent solution or by asimple, rapid, heatsealing operation. The solvents adaptable for the particular thermoplastic resin employed are well known to those skilled in the art and in general, acetone, propylene oxide, ethylene dichloride, mesityl oxide, or the higher.ket0nes are satisfactory. A simple heat-sealing operation can be performed with a soldering iron but the use of a solvent solution is preferred. The solvent solution may be fortified with the particular type of plastic used so that the threads are more positively coated and the holes more perfectly sealed.
The use of threads made of the same or similar type of thermoplastic resin to perform the required stitching is also recommended since the material is waterproof and the threads and liner L fuse by virtue of the applied solvent.
Fig. 2 illustrates the application of such a. solvent l5 to the stitching l2 and it, although it need only be applied to one line of stitching to be effective.
to secure the sweat-band to the hat body withoutthe use of stitching, the solvent being applied in the form of a liquid solution or heat and pressure.
In the preferred embodiment the side H of the liner L extends slightly above and below the sweat-band 13 so that perspiration cannot travel from the top or bottom of the sweat-band to the lining or body of the hat.
I have shown a preferred embodiment of my invention but it is obvious that numerous changes and omissions may be made without departing from its spirit.
1. A method of securing a sweat-band to a hat which comprises stitching said sweat-band to a liner of a thermoplastic resin by thread of the same material as said liner, stitching said liner to the hat body with said type of thread, so that said liner is between said sweat-band and said hat body and applying a solvent of said liner and thread over at least one of said stitched portions of said liner.
2. A hat construction comprising a hat body, a sweat-band, and a liner of a thermoplastic resin disposed between said sweat-hand and hat body, said hat body being connected to said liner and said liner being connected to said sweat-band at least one of said connections includingan impregnation'of one of said connected elements by said thermoplastic liner.
3. A hat construction comprising a hat body, a sweat-band and a liner of a thermoplastic resin disposed between said sweat-band and hat body, said hat body being connected to said liner and said liner being connected to said sweat-band, at least one of said connections being affected by thread stitching and at least one of said connections including an impregnation of one of said connected elements by said thermoplastic liner.
thetic resin disposed between said sweat-band and said hat body, said hat body being connected to said liner bya first row of thread stitching and said liner being connected to said sweatband by a second row of thread stitching, at least one of said rows of thread stitching being coated and permeated with thermoplastic material integral with said thermoplastic liner.
5. A hat construction comprising a hat body, a sweat-band and a liner of a thermoplastic synthetic resin disposed between said sweat-band and said hat body, said hat body being connected to said liner by a first row of thread stitching and said liner being connected to said sweatband by a second row of thread stitching, said stitching comprising thread of a thermoplastic synthetic resin, at least one oi said rows of thermoplastic thread stitching being impregnated with thermoplastic material rendering said liner and said impregnated row of stitching integral.
6. A hat construction comprising a hat body,
, a sweat-band and a liner of a thermoplastic ma- 4. A hat construction comprising a hat body,
a sweat-band and a liner of a thermoplastic synterial disposed between said sweat-band and said hat body, said hat body being connected to said liner and said liner being connected to said sweat-band. one of said connections comprising a row of thread stitching, said thread stitching being of thermoplastic material and being coated with thermoplastic material whereby said liner and thread are rendered integral.
