PROTECTIVE DEVICE Filed July 11, 1940 INVENTOR.

QM 7M ATTORNEY.

Patented Feb. 10, 1942 rice This invention relates to a new type of adjustable head gear worn over the head, supporting a shield suitable to protect the face and eyes of a user engaged in welding, grinding, chemical, wood, or metal working, or other work necessitating protection of the head, face, and eyes.

More particularly, this invention relates to an axially adjustable face protecting device supported in spaced relation upon a headband, the latter being provided with resilient means rendering said headband comfortably adaptable to different sized and shaped heads.

The object of this invention is the provision in a face-protecting device of a headband with the inside thereof of a substantially continuous smooth curvature, whereby an even tension is produced entirely around the operators head, eliminating bumps and other irregularities therein, which heretofore have occasioned disc'omforture.

It is the object of this invention to provide a headband with the ends thereof separated and arcuately movable with respect to each other, and with an inner intermediate member slidably mounted on said end portions whereby a continuous head-engaging band is formed, adapted to a plurality of head sizes.

It is the further object of this invention to provide means integral with said inner intermediate member slidably engageable with the loose end portions of the headband, whereby adjustment thereof is accomplished with a minimum of friction, at the same time maintaining substantial rigidity.

It is the still further object hereof to provide in a protective device of this class, an adjustable resilient means between the loose ends of the headband whereby the same is readily adaptable to a plurality of headsizes and also readily adaptable to various positions upon the operators head.

It is the further object of this invention to provide means on said intermediate member to act as a stop for the ends of the headband, and

at the same time prevent the head gear from becoming accidentally disassembled.

It is the further object hereof to provide a featherweight construction with ample ventilation, so designed that the shield may be worn over prescription glasses.

It is the further object of this invention to provide a pivotal connection between the rotatable shield, and headband, with a resilient friction means interposed therebetween, whereby said shield may be rotatably adjusted and secured upon an immovable pivot.

It is the further object hereof to provide pivots for the back band, disposed independently of the shield assembly pivots, whereby a better grip is accomplished by the rear band upon the back portion of the head, and whereby a substantially continuous inner curvature relation between the front and back bands results.

The invention hereinafter described in detail relates to the various arrangements of parts and combinations thereof, as shown in the drawing, of which:

Figure 1 is a side elevational view of the headgear.

Figure 2 is a top-plan view thereof.

Figure 3 is an enlarged rear-end elevational view of the headband forming a part of said headgear.

Figure 4 is an enlarged sectional segment of the shield pivotal connection.

It is understood that the drawing referred to is merely by way of illustration, as preferable embodiments of the invention, and that the inventor herein does not intend to be limited thereby.

In the drawing, the protective device consists of a fibre headband Ii, a shield l2 pivotally mounted thereon at points 26, and a transversely positioned semi-circular headband supporting fibre member I3 also pivoted at points 25.

'In the preferable embodiment of the invention, the elastic members are made of steammoulded fibre segments.

The headband H consists of an arcuate front member l4 to which is pivotally secured at points 26 a rotatable shield supporting member I5, said support providing forehead protection. The shield l2, preferably made of a transparent non-inflammable material, or other non-inflammable material with a sight opening, preferably cellulose acetate, downwardly depends from said rotatable shield support I5, being removably secured thereto at points Hi.

The rear portion of the headband ll consists of arcuate members I! and I8 loosely riveted on their ends at points 19 to the end portions of the front member 14 and on the outside thereof. Members l1 and 18 of steam-moulded fibre are flexible, and are designed for radial flexion, whereby the peripheral size of the headband may be varied as required to fit the individual head.

An intermediate flexible member 2i] is slidably disposed within and upon members I! and I8 by means of a plurality of clips 2|, the latter being riveted to said intermediate member 20 at points 22. It will be noted that clips 2| are spaced relatively far apart and have minimum bearing surfaces on the sliding members I! and Hi, whereby rigidity is obtained for headband H, at the same time minimizing friction.

Intermediate member 29 is positioned within expansible members I! and I8 in order that a smooth and comfortable head-engaging surface is obtained within headband l I. It is seen, then, that the inner surface of member 20 coincides and co-operates with the inner surface of member M to form a substantially continuous, comfortable head-engaging surface.

A resilient adjustable connection is provided between the ends of members I! and I8 by means of clips 23 riveted thereto. An elastic member 24, preferably made of rubber or other resilient material, is slidably disposed through clip 23 and has buckles 25 adjustably disposed adjacent its ends, outside clips 23.

It will be noted that clips 2| shown in Figure 3 co-operate with clips 23, and thus positioned with respect to each other, prevent the headband from becoming accidentally disassembled. It is seen also that buckles 25 are readily adjusted to any desired position. Resilient connection 24 enables the headband l l to comfortably seat upon an operators head, and is never tight enough to interfere with circulation.

The rear portion of headband ll comprising members I! and I8 is loosely riveted at points IS on the ends of member l4, enabling an operator to axially rotate said rear portion to other points on the back of the head by virtue of the resilient connection 24 between members I! and It. The adjustment is easily accomplished without the need of loosening screws, bolts, or other devices.

Being pivoted at points l9 behind the shield pivots 26 a more acute angle may be obtained between the rear portion of the headband and the front portion thereof, whenever said rear portion is tilted upon the back of the operators head. Consequently a better grip is obtained.

Referring to Figures 2 and 4, arcuate member I I 4 has disposed through square openings in its ends headed pivot screws 26, having square portions 21 co-operating with said openings whereby a non-rotatable relation is maintained between parts M and 26.

Head-engaging band IS with openings on its ends is loosely and rotatably journaled on said screws adjacent headband member I4.

A resilient spring steel or other washer 28 journaled on screw 26 provides, when compressed, a frictional relationship at said pivotal connections.

A fibre washer 29 is interposed between washer 28 and the ends or the shield support I5, and a bushing 30 with a square opening to co-operate with the square portions 21 is disposed on the outside of said rotatable shield support l5. Con- :Sequently, the latter rotates on the bushing, while said bushing remains fixed with respect to screw 26.

A knurled hand adjusting nut 3| threadedly journaled on screw 26 provides for manual adjustment of said pivotal connection.

By this precision construction, a positive pivot assembly is provided and consequently, any rotative movement of the shield and its support 15 is independent of headband l I, so that nut 3| will not work loose.

The spring washer 28 is designed to exert an even frictional compression whereby the shield is at all times maintained in adjusted position.

By separately pivoting members I! and IE, it is seen also that their rotative adjustment is entirely independent of the pivotal adjustment of the shield with respect to the headband. This has an advantage in permitting the user to rotatably regulate the back portions l1 and I8 of said headband to various restful positions on the back of the head, without interfering with the position of the shield.

When not in use, the face guard l2 and its support are rotatable upwards on said screws 26, tightening adjustment being provided by means of knurled nuts 3|, threadedly journaled on the ends of said screws.

Member l4 forming a part of headband H is disposed in spaced relation to the surface of shield l2 and its support l5. Said member I4 may be provided with a padded sanitary and comfortable perspiration-resistant band 32, suitably secured thereto. Similarly, though not shown in the drawing, it is contemplated that a sweatband be also provided upon the rear portion of the headband such as on the inside surface of member 20, thereby providing a substantially continuous inner curvature in relation to the padded sweatband 32.
