15 Claims. (Cl. 2-3) This invention relates to molded protective hats, and more particularly to the means by which the hats and their linings are connected together.

Protective hats of this character are formed by molding together laminations which may be made from fabric or from oriented or unoriented fiber mats with a suitable plastic. Such hats are well known and are disclosed in many patents. Inside each hat there is a lining which supports the hat on the head and spaces it therefrom. In the past this lining has been connected to the hat in various ways, such as by a lace extending through holes in the side of the hat or by metal fasteners also extending through the side of the hat. In some cases the old arrangements for connecting the linings in the hats are objectionable because of the holes in the hats or because the metal fasteners extend entirely through the hats and thereby form conductors for electricity.

It is among the objects of this invention to provide a molded protective hat in which the fasteners or anchors for the lining are secured to the hat during the molding operation, and in which the anchors do not extend through the hat. Another object is to provide a new and improved connection between a hat lining and its fastening members secured to the hat.

In accordance with this invention, a plurality of metal anchors are disposed at circumferentially spaced intervals around the lower surface of a molded protective hat which is formed from bonded laminations. A portion of each anchor is secured between two laminations, while the rest of it is exposed for connection to a hat lining. Preferably, the lower lamination is provided with openings through which the anchors extend, and each anchor may be provided with a slot through which a tongue, integral with the lower lamination, may extend. The portion of the tongue between the anchor and the next lamination is bonded to the latter. The exposed portions of the anchors are provided with openings through which connecting members extend for securing a hat lining thereto. Preferably the connecting members include hooks which may be locked in the anchors by spring tongues integral with the anchors. The connecting members also may be provided with manually actuated portions for moving the spring tongues out of engagement with the hooks so that they can be disconnected from the anchors.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which Fig. l is a side view of a protective hat, broken away to show part of it in section;

Referring to the drawings, a protective hat is molded in conventional manner from two or more superimposed laminations, three

laminations

1, 2 and 3 being shown in Fig. 3. Although these laminations or layers may be felted or unfelted mats, the ones shown are sheets of woven fabric. They are impregnated with a suitable thermosetting plastic so that when molded under heat and pressure, a strong and rigid hat is formed. In the hat shown, the lower surface of the sloping brim is formed from the lamination 3 which, before it is molded, is referred to as the doughnut because it has a large hole 4 (Fig. 4) in the middle so that it will not cover the inside of the crown of the hat. This lamination adds thickness and stiffness to the brim.

Inside the hat is the lining, which may consist of a sweatband 6 supported by cradle straps 7 that fit over the head in a well known manner. The lining is connected to the hat, to support the hat spaced from the head, by means of connecting members. Each connecting member includes a hanger 8 formed from a rather stiff plate that is bent about midway between its ends to provide an upper portion substantially parallel to the side wall of the crown and a lower portion that extends out beneath the brim. The upper portion of the hanger is provided with a transverse slot 9 that is slidably mounted on a rivet 11 extending through the outer thickness of the double thickness sweatband, whereby the band is adjustably connected to the hangers. The lower portion of each hanger is provided near its opposite edges with a pair of parallel slits 12, and a hook member 13 extends across the hanger and has its central portion engaging the upper surface thereof and its opposite ends extending through the slits. The projecting ends of the hook member are bent up into notches 14 in the edges of the hanger to hold the hook member in place. The hook member is provided with a slot 16, through which the adjoining cradle strap is looped to connect them together. The central portion of the hook member, outwardly of its slot, is partly separated from the rest of the member and is bent upwardly to form an inwardly extending hook 17 for hooking onto an achor member 18 carried by the hat.

In accordance with this invention the anchors 18 for the hat lining, which most suitably are made of stainless spring steel, are secured to the hat in the following way. As shown in Figs. 2 and 4, the lower lamination 3 is provided at several circumferentially spaced points, preferably four, around its central hole with inwardly extending radial tongues 21, formed by cutting the doughnut. Each of these tongues extends down through a transverse slot 22 in one of the anchors and inward between the anchor and the next lamination 2. Consequently, the outer portion of the anchor is sandwiched between

laminations

2 and 3, and its inner portion is exposed. At the opposite ends of the anchor slot the lower lamination is cut transversely of the anchor out to the side edges of the inner portion of the anchor so that the full width of that portion can be exposed. Preferably, the same lamination is cut away from the outer ends of these last-mentioned cuts to its inner edge (the edge of hole 4) to form recesses 23 extending along the opposite sides of tongue 21 that facilitate placing the anchor in The outer portion of the 3 anchor, which is locatedbetween two laminations, may be provided with lateral projections 24 that extend outthrough radial slits in the lower lamination. These also. help to hold the anchor in position.

As shown in Fig. 3, each spring n'iet'alaiihoi is b nt transversely to space its exposed inner portioihfroiiii are heat brim. Although the anchor is flattened during molding, it springs away frorr'i the orini asso'oiiasthe-riiolding pressure is released. To protect the mold from rising scratched and to insure that the inner portioh of the anchor will not stick to the brim, before the hat is molded the exposed portion of eachanchor is wrapped in a suitaole heat resistant masking tape (not shown), such as cellophane. When the nrnihassnssreherded together to form thehat, the outer poi-tide or the-anchors between the laminations are embedded therein and the tongues 2i are bondedto the adjoining lamination 2. Each anchor therefore has an end p'ortioii that is em bedded or moldedbetween two laminations, and ah ex osed end portion to which the Hat liniiig can Be 6611" nected,

Although the anchors may be shaped in various ways for sensation to the hat lining, a preferred way is" to rovide their inner ends with openings 2'61ihat allow the connecting members to be Hooked onto them. To look the liools 17 in the anchors, each aiicho'r' may be pro"- vided irrits opening with an inwardlyp'rme'cting spring; tongue'27; the point of which will spring into a'nofch' 28 iii the Base of the adjoining hook and thus prevent the husk-seal being withdrawn from the anchor, as s'hhwn' in Fig; 3. For unlocking the hooks the lower ortion of each haiiger s is slit to form an outwardly extending flexible tongue 29 that carries a pin 30 which engages the adjoinihg spring tongue of the anchor. when the not; ible hanger tongue is pressed toward the hat brim, the pin 30 pushes the spring tongue 27 out of the hook notch to allow the hook to be slid out of the anchor opening.

Two of many other forms of anchors that may be used are shown in Figs. and 6;. Although these may be made of heavy fabric or the like, it is preferred to make them of metal. The one shown in Fig. 5 can be conne'cted to a doughnut inthe same way as anchor 18. It is proi/ided with a slot 35 for receiving a doughnut tongue 21, another slot 36 through which a cradle strap can be looped. In this case the strap is connected directly to the anchor instead of through an intermediate connecting member.

The anchorjshown in Fig. 6 is used with a doughnut thatdoes not have tongues, but iristead has slits through which these anchors extend. The exposed inner portion of each anchor is provided with one or more holes 58, by which it can b' cofihcdted to a hat liniilg iii any suitable mariner. 1 V A Iii the embodiment of the invention illustrated in Figs; 7,} and 9, the spring metalanchor 40 has atransverse slot 41 through it, through which extends a radiahtong ue 21 cut in the lower lamination 3 The tongue is bonded to the lamination 2 above it. The outer'port-ion of the anchor, between

laminations

2 and 3 is provided with lateral projections 42 that extend out through radial slits in the lower lamination to help hold the anchor in place; The anchoi has an exposed wide central part, in theouter end of which slot 41 is located. On opposite sides of this portion there are parallel narrow tongues 43; The masses and the rectangular portion between them are bent transversely down away from the hat brim; but the free'end s' of the tongues are bent back up against the brim so that both ends engage it.

Supported by the lower part of each cradle strap 7 is a hook member 45 that preferably is rectangular. The

chor slot 41. The opposite sides of the hook member are ceiitrla'l part has a large opening 46, through which are strap is l'obped. At the lower or outer side of this opening'there is an inwardly extending hook 457 that is curved d the brim and then inwardly. To connect the brim at the outer sides of tongues 43. The side portions of the hook member beside opening 46 are provided with a pair of up-struck tongues 49 that have their free ends extending up toward the free ends of anchor tongues 43 in engagement with them. Consequently, the two pairs of tongues cooperate to lock the hook member in the anchor until the hook member is pulled outward with sufficient force to cause the tongues to flatten enough to ride over each other. The hook member can bestraightened and prevented from tilting, which might separate the tongues, by providing its outer edge with an up-turned flange 50 that engages the lower lamination covering the outer portion of the anchor.

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