3 Claims.

This invention comprises a detachable sweat band of new and improved construction for use in connection with protective head guards, helmets, shields and the like worn by industrial workers such as welders and foundry men.

In general it is the object of the invention to provide a sweat band having large capacity for absorption and of such construction that it may be easily and rapidly attached to and detached from a bowed supporting member so that replacement is made convenient for the wearer, contact with the face is made comfortable, and construction of the article inexpensive. All these and other advantages are achieved in the band of our invention which is characterized by a felt body having cover strips attached to the two edges of one face and extending oppositely in overlapping relation so that they tend to conform in fiat condition to the felt body. When a band of this construction is applied to a bowed supporting member, the cover strips are immediately placed in tension and the band as a whole is thus held securely in place by the resulting friction. We thus eliminate the necessity for studs, snap fasteners Or the like which have been heretofore considered necessary, and have not only added to the expense of the bands which have been available but take up room and present objectionable projections and irregularities in the contour of the band.

We have also discovered that the capacity of the felt body of a sweat band and the rapidity of its absorption may beadvantageously increased by treating the band with a suitable wetting agent, and this step constitutes another important but optional feature of our invention.

These and other features of the invention will lowing description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawing, in which:

Fig. 1 is a View in perspective of a head guard and shield equipped with our detachable sweat band,

Fig. 2 is a plan view of the component parts thereof,

Fig. 3 is a View in perspective of the band as shown in flat condition, and

Fig. 4 is a fragmentary sectional view on the line 4-4 of Fig. 1 and on an enlarged scale.

The head guard shown in Fig. 1 comprises a circular adjustable band IQ of hard fibre or the like having its rear ends adjustably connected by a curved sleeve II in which is set a clamping screw I2. Pivotally mounted upon the band I be best understood and appreciated from the folat opposite sides thereof is a visor I3 carrying a transparent shield I4. As indicated in this figure, 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.

The forepart of the band 10 is equipped with an absorbent sweat band comprising the elements shown in Fig. 2. These include a straight strip of felt I5 preferably treated with a wetting agent such as Alkanol (alkylnaphthalene-sodium-sulfonate). The wetting agent substantially increases the rapidity and capacity of the felt strip for absorption. Any suitable wetting agent having the general properties of Alkanol may be successfully employed. To the body strip I5 are united two cover strips I6 and I1, shown in Fig. 2 as being of the same length as the body strip and scalloped at one edge. The cover strips may be of thin felt or other textile material. They are secured to the body strip I5 by being stitched to the opposite edges of one face, that is to say, the face that is outermost in the assembled device. As shown in Fig. 3, the strip I6 is stitched to the lower edge of the body strip I5 and lies in contact with its surface. The strip I1 is stitched to the upper edge of the body strip I5 and overlaps the strip I6. Both of the cover strips are slightly narrower than the body strip so that they may lie naturally in flat overlapping position.

In order to attach the composite band thus provided, it is necessary only to fold back the two cover strips. apply the inner face of the body strip directly to the inner face of the band I 0, and then fold the cover strips down upon the outer face of the band It]. The composite textile band is thus supported with a pronounced convex curvature so that the cover strips I6 and I1 are subjected to substantial tension thus developing friction between each other and also between the textile band and the supporting band In which holds the textile band firmly in place. At the same time it may be easily detached and removed by merely folding the cover strips up and down to clearthe supporting band I0.

It will be understood that the shield shown in Fig. 1 is only one of the devices in which we contemplate employing the composite textile sweat band herein illustrated. It may be usefully employed in any device having a bowed supportin member carrying an absorbent pad in contact with the face of the wearer.

Any wetting agent having the general characteristics of Alkanol may be employed in treatband co prising a feltbody strip, and cover strips sewn to the two edges of one face of the said body strip, extending oppositely in overlapping relation and being tensioned upon the convex face of the supporting member while the felt body strip is conformed to its. concave face.

2. A detachable sweat band adapted to be conformed to a bowed resilient supporting member and comprising a felt body strip, and cover strips attached to the body strip at opposite edges of one face thereof, extending oppositely in overlapping relation, and arranged to be tensioned when the band is longitudinally curved.

3. A detachable sweat band for use with a protective head guard, comprising a flat straight body strip of felt of uniform width and thickness from end to end and having a wetting agent distributed therein, and a pair of cover strips both of less width than the said body strip and being attached respectively to opposite edges of one face of the body strip and overlapping each other, thus developing frictional engagement when the band as. a whole is longitudinally bowed.
