Claims. (Cl. 2—9) such as aluminum or the like. Rivets 19 extend through the holes 17 in the brackets 16 and through the brow piece 12 for securing the channel member 13 to the brow piece 12. Intermediate its ends, the inner leg 14 is also provided with a pair of holes through which rivets 20 extend, also for securing the channel member 13 to the brow piece 12. The outer leg 15 of the channel member 13 is provided with holes 21 in alignment with the intermediate rivets 20. A pair of spring members 23 provided with holes 24 are secured in place on the brackets 16 by the rivets 19, which secure the brackets 16 to the brow piece 12, and the outer free ends of the spring members 23 are provided with inwardly facing buttons 25 which, in turn, extend through the holes 26 in the outer leg 15 of the channel member. By manipulating the spring members 23, the buttons 25 may be inserted through and drawn from the holes 26.

A resilient transparent face piece 28, which may take the form of a suitable transparent plastic sheet, has its upper edge closely received in the channel member 13. The face piece 28 is provided adjacent its ends with a pair of slots 29 which are in alignment with the pair of holes 26 in the outer leg 15 of the channel member 13. When the buttons 25 on the spring members 23 are inserted through the holes 26 in the channel member 13, they are also snapped through the slots 29 in the face piece 28 for releasably securing the face piece 28 in place in the channel member 13. By reason of the slots 29 the face piece 28 and the channel member 13 are allowed to expand and contract with respect to each other so that thermal expansion and contraction conditions will not operate to distort or buckle the face piece 28. When the face piece 28 is inserted in the channel member 13, it is deformed slightly between the inter³⁵ mediate rivets 20 and the aligned holes 21 in the outer leg 15 of the channel· member 13, which also operates releasably to secure the face piece 28 in the channel member 13. In this way, the face piece 28 is quickly and readily releasably secured in the channel member 13 face piece is readily accomplished.

The adjustable head band 11 includes an open ended flexible sleeve 32 which is preferably formed of a soft _ flexible plastic material. This sleeve 32 has an inner ⁴⁵ wall 33 and an outer wall 34. The outer wall 34 of the sleeve is provided intermediate its ends with a pair of spaced-apart transverse slits 35, these slits dividing the sleeve into a central portion between the slits and side portions between the ends of the sleeve and the slits. An outwardly facing button 36 is secured to the outer wall 34 of the central portion of the sleeve between the slits 35. A flexible strap 38, preferably formed of a soft flexible plastic material, extends between the open ends of the sleeve 32 and has two ends 39 and 40. The end 39 of the strap 38 is threaded through one side portion of the sleeve 32, through one slit 35, over the outer wall 34 of the central portion of the sleeve, and through the other slit 35 into the other side portion of the sleeve 32. In a like manner the other end 40 of the strap 38 is threaded through said other side portion of the sleeve 32, through said other slit 35, over the outer wall 34 of the central portion of the sleeve, and through said one slit 35 into said one side portion of the sleeve 32. The ___ 5 illustrated herein, the end 39 of the strap lies inwardly from the end 40 of the strap. The ends 39 and 40 of the strap 38 are each provided with a plurality of longitudinally spaced holes 41, which selectively receive the between the slits 35. By inserting the button 36 through the desired holes 41 in the strap ends 39 and 40, the perspective view of the adjustable head band ⁴⁰ and, hence, to the brow piece 12, and replacement of + .. ..... .i _____ 4» τ·λο/4ϊ1τι· ornnmnlidlAn

The principal object of this invention is to provide an improved face shield and adjustable head band therefor, wherein the transparent face piece may be quickly and readily releasably secured to the brow piece of the face shield, wherein relative thermal expansion and contraction between the face piece and brow piece is provided even though the two pieces are firmly secured together, wherein the face shield is pivotally mounted on the head band in a simple manner to allow easy manipulation of the face shield, wherein the head band is quickly and readily adjusted to fit the head of the wearer, and wherein the head band is soft and flexible with no metal parts touching the head of the wearer so as to provide maximum comfort. .

Further objects of this invention reside in the details ot construction of the face shield and adjustable headband and in the co-operative relationships between the component parts thereof.

Other objects and advantages of this invention will become apparent to those skilled in the art upon reference to the accompanying specification, claims and drawing in which: , .

The face shield and adjustable head band of this invention are generally designated at 10 and 11, respec- go tively. The face shield 10 includes a curved brow piece 12 having a curved portion at the bottom thereof, the brow piece 12 being relatively stiff and preferably being formed from plastic impregnated paper board or the like. —------------ . .

A curved channel member 13 is secured to the outer gg ends 39 and 40 of the strap overlap each other and, as surface of the curved brow piece adjacent the bottom edge thereof, the channel member having downwardly extending closely arranged inner and outer legs 14 and 15, respectively. Each end of the _ channel member 15 is provided with a L—i—-- —---, ~ . 7” with holes 17 and 18. The channel member 15, including its brackets 15, is preferably formed from metal bracket 16 which, in turn, is provided 70 outwardly facing button 36 carried by the outer wall 34 * a . a » _z_1_ - -111- d ΊΟτ» fno ηΐΙΓΤΛΠ T ΠΉ/ΛΊ1 CTrl

2,829,374 3 encircling length of the strap 38 is quickly and readily adjusted. ¹^T1lV-^{e sbieId 10 is} pivotally mounted on the adjustable head band 11 and this is accomplished bypassing rivets through the outer wall 34 of the sleeve 32 adjacent the ends thereof and the holes 18 in the brackets lo. , Washers 44 and 45 are arranged on opposite sides of the brackets 16 and are drawn up snugly by the rivets 43 so as to provide a frictional type of pivoting action. By reason of these pivotal connections between the adjustable head band 11 and the face shield 10, the face shield may be readily manipulated with respect to the face of the wearer. Since the adjustable head band l~.^{ls s}°ft ^anci flexible and since there are no metal parts which can touch the head of the wearer, the face shield and adjustable head band of this invention may be worn with maximum comfort.

. While for purposes of illustration, one form of this invention has been disclosed, other forms thereof may become apparent to those skilled in the art upon reference to this, disclosure and, therefore, this invention should be limited only by the scope of the appended claims
