Lehmberg, Riverside,‘ Conn., and Ernest L. Johnson, Port Chester, N. Y. Application June 19, 1946, Serial ‘No. 677,724 ~' 3 Claims. 1 This invention comprises a detachable sweat band of new and improved construction for use in connection with protective head guards, hel mets, shields and the like worn by industrial work ers such as welders and foundry men. (Cl. 2-181) 2 at opposite sides thereof is a visor I3 carrying a transparent shield I4. As indicated in this ?g ure, the visor may be swung from an inoperative position as shown in full lines to an operative position before the eyes of the wearer as shown in dotted lines. In general it is the object of the invention to The forepart of the band 10 is equipped with provide a sweat band having large capacity for an absorbent sweat band comprising the elements absorption and of such construction that it may shown in Fig. 2. These include a straight strip be easily and rapidly attached to and detached from a bowed supporting member so that replace 10 of felt I5 preferably treated with a wetting agent such as Alkanol (alkylnaphthalene-sodium-sul ment is made convenient for the wearer, contact fonate). The wetting agent substantially in with the face is made comfortable, and construc creases the rapidity and capacity of the felt strip tion of the article inexpensive. All these and for absorption. Any suitable wetting agent hav other advantages are achieved in the band of our invention which is characterized by a felt body 15 ing the general properties of Alkanol may be successfully employed. To the body strip I5 are having cover strips attached to the two edges united two cover strips I6 and I1, shown in Fig. of one face and extending oppositely in overlap 2 as being of the same length as the body strip ping relation so that they tend to conform in ?at and scalloped at one edge. The cover strips may condition to the felt body. When a band of this construction is applied to a bowed supporting 20 be of thin felt or other textile material. They are secured to the body strip I5 by being stitched member, the cover strips are immediately placed to the opposite edges of one face, that is to say, in tension and the band as a whole is thus held the face that is outermost in the assembled de securely in place by the resulting friction.
