4 claims. (o1. 2 3) This invention relates to rigid protective hats, and jmore particularly to means for supporting such hats on the head.

A well-known type ofprotective hat has a high rigid crown surrounded by an integral rigid brim. Such a hat is held on the head and spaced from it by means of a lining, consisting of a sweatband and a cradle that ts over the head, and also a liner band between the sweatband and crown. The liner band or the lower ends of the cradle straps jareconnected to the lower part of the crown in one way or another, such as by a lace extending in and out through perforations in the crown, or by metal kfastening members extending through the crown. Under many conditions of use of the hat, perforations through it or exposed metal fasteners are objectionable. Moreover, blows against the crown are transmitted to the hat liner through the lace or the fasteners only at spaced points `around the hat, thereby concentrating the shocks at those points.

It is among the objects of this invention to provideA for a protective hat an annular support which supports the hatfrom the lining without requiring .metal fasteners or perforations in the crown, which causes blows against the crown to be transmitted to the lining through the brim throughout the circumference of the brim, which is'spaced from the crown, and which is inexpensive and easy to attach to the hat.

In accordance with this invention, the support consists of a relatively stiiT annular member havin g an, upper band-like portion extending a short way' up into the crown of a rigid protective hat adjacent the inner surface of the crown. The support also has a ange surrounding the lower end of its upwardly extending portion and extending out along the underside of the brim of the hat. YThe outer edge of this flange is provided with -an upwardly and inwardly extending marginal-portion, so as to form a channel for receiving the edge of the brim in order to connect the support to the hat. The support is made of plastic material which is stiff enough to hold its shape,

but which has enough stretch to permit it to be applied to the brim of the hat. The band-like portion of the support inside the crown is formed to support Ia hat lining.l Thus, it may be provided with circumferentially spaced horizontal slots, through which the lower ends of cradle straps may extend. The straps also can support a sweatband inside the hat.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which Fig. 1 is a plan :view fof a protective hat with a portion ofthe kcrown broken away toshow part of the lining; and Fig. 2 is a verticalsection and side view of the hat taken on the line II-LII ofFig. 1. A v i Referring to the drawingsthe hat may be made of any material which will giveit the necessary rigidity., Forl most purposes it will be a nonmetallic material, such as a molded composition. Such hats are well known and generally have a high dome-like crown I surrounded by an integral inclined brim 2. The hat is made as rigid and strong as possible. Inside the crown there is a lining which, in the .embodiment shown, includes a flexible liner band 3 supported by the lower ends of cradle straps 4. The upper endsl of the straps are fastened to a pad 5 that rests on top of the head. The lower `part of the band supports the lower edge of a sweatband 6 that extends up through .the liner band.

This invention is directed primarily to the means by which the hat lining is connected to the hat, so that the hat will be supported on the head by means of the lining. Accordingly, the connectingmeans just mentioned consists of a single member in the form of an annular vsupport which has an upper band-like portion I0 that extends a short distanceup into the crown ofthe hat between liner band 3 and the side wall of the crown. Preferably, it is spaced a short distance from the crown. Surrounding the lower endof upper portion I 0 of the support is :an integral flange l I that extends out along theunderside of the hat brim ,substantially parallel to it. To

connect the annular support to the hat, the outer edge of llange Il is turned up and back on itself all around the support to form an upwardly 4and inwardly extending marginal portion l2 overlapping the marginal portion `of the hat brim.

In other words, the turned-'back portion of lthe ange forms between itself and the underlying area of the flanges, channel extending .around the support for receiving the edge vof the fbrim.

It will be seen that :before the hat vbrim `can be inserted in all of the channel of the lannular support, the support has to be stretched out to some extent to permitmarginal portion VI 2 to snap over the brim. `'On the other hand, the support must be :stiii` enough to hold its `shape so lthat it i will :not pull off the' hat brim, but will stayin its proper location inthe hat and not collapse. A material that is suitable for this yuse is -,a..plastic. such as alinear polyamide resin, a Epolyvinyl chloride .or `a cellulose .acetate-butyrate. vThese plastics can be molded under heat and lpressure into relatively sti or rigid material, yet one which can be stretched enough to slip the support .disclosed herein over the :edge lfof a hat brim. To

add rigidity to the flange Il of the support without interfering with stretching it into place, the ange may have several radial ribs I3 molded into it. Preferably, the ribs are formed on the upper surface of .the iiange and engage the lower surfaceof the hat brim. Also, it is'desirable to make the portion of the iiange that hooks around the edge of the hat brim a little thicker than the rest of the support so that it will be stronger and hold its shape better.

Although there are various ways of fastening the hat lining to the annular support just described, the preferred way is to provide the upper portion l of the support with a plurality of circumferentially spaced horizontal slots beside similar slots in liner band 3, and then pass the cradle straps through the adjacent pairs of slots so that both the sweatband and support are suspended from the straps. Again, this may be 'done in various ways. In the arrangement shown, each strap 4 extends downward from head pad 5 and out through a slot I5 in the liner band and through the lower one of a pair of vertically spaced slots I6 and I1 in the annular support. Thestrap then extends upward and then inward across the tops of the support and liner band, 'and then down and again out through band slot Vi5 and the upper slot l1 in the support. The strap then extends down and back through the lower slot I6 and band slot l5 again, and then upward to a point near pad 5. This free end of the strap is provided with a loop so that a lace I8 can extend through the loops of all of the straps to hold them in place. By tightening or loosening the lace, the elevation of the pad in the crown can be adjusted for heads of different sizes. By spacing the upper portion l0 of the annular support a short distance from the surrounding wall of the crown, blows that strike the side of the crown are less likely to be transmitted directly to the head oi the wearer.

' By utilizing the invention disclosed herein it becomes unnecessary to provide the hat with perforations or-fasteners extending through the wall of the crown. The lining can be attached to the plastic annular support, and then the latter applied to the brim of the hat. This is a quick and relatively inexpensive way of fastening the lining in the hat. Any blows against the hat are transmitted to the lining through the edge of the brim and the annular supportl and therefore the shock is distributed more or less uniformly around the entire hat.

According to the provisions of the patent statutes, we have explained the principle of our invention and have illustrated and described what we now consider to represent its best embodiment. However, we desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
