Figure l() is a perspective view of a face piece in the form of a wire mesh face shield.
Figure ll is a perspective View illustrating a face piece in the form of goggles releasably connected to a head piece in the form of a head band.
The drawings illustrate various types of head pieces such as a hard hat generally designated at 1t) in Figures l, 3, 4 and 7, a head band as illustrated at 11 in Figures 2 and 8 and a head band as illustrated at 12 in Figure 1l. 'I he drawings also illustrate various forms of face pieces 2,801,420l Patented Aug. 6, 1957 ICC such as a wire mesh face shield 13 as illustrated in Figures 1, 3, 4 and l0, a welders face shield 14 as i1- lustrated in Figures 2 and 9 and a pair of goggles 15 as illustrated in Figure 11. These various face pieces, in accordance with this invention, may be interchangeably and releasably connected to the various head pieces.
Referring now more particularly to Figures 1, 3, 4 and 7, the hard hat 10 includes a crown portion 17 and a brim portion 18, which may be formed of any suitable material such as a hardened synthetic plastic material or compressed iiber or the like. The hard hat is provided with a head harness including a head band 19 and head straps 2o. The head straps 2t) are looped at their ends as indicated at 21 and these loops extend through slits 22 in the head band 19 and through clips 23, which are detachably secured to the crown portion 17 of the hard hat. The harness is adjustable so that the hard hat may be firmly supported on the head of the workman.
A pair of members 25 are permanently secured to the crown portion 17 of the hard hat. Each of these members 25 includes a pair of offset and outwardly facing diverging legs 26 and 27, these legs being spaced from the crown portion 17 of the hard hat. The lower ends of these diverging legs 26 and 27 terminate in lugs 28 and 29 which act as stops. A leaf spring 36 provided with a cam projection 31 is located between the offset diverging legs 2d and 27. The leaf spring 30 is securedl to the member 25 and the member 25 is secured to the crown portion 17 of the hard hat by means of rivets 32.
The face piece 13, in the form of a wire mesh face shield, as illustrated in Figures l, 3, 4 and 10, includes a visor portion 35 provided with a securing rim 36 to which a wire mesh screen 37 is secured by screws 38. The wire mesh screen 37 may be provided with a reinforcing fiange 39. A pair of brackets 40, each having a square hole 41 are secured to the securing rim 36 by rivets 42. A member 43 has a squared end 44 which is received in the square hole 41 of the bracket 40 and it is provided at its other end with a flange 45. It is also provided with an internal hole having flat portions 46. A liber washer 47 abuts against the outer surface of the bracket i0 and is backed by a metal washer 48 which in turn is engaged by a head 49 of a screw 50. Thus, the member 43 is secured to the bracket 4t) and is secured against rotation. A member 51 having iiat surfaces is received in the member 43 and by reason of the flat surfaces, rotation betweenthe members 51 and 43 is prevented. The member 51 is provided with a ange 52. A spring 53 is received in the member 51 and is backed by a nut 54 screwed onto the screw 50. One leg of a U-shaped bracket 55 is located between the flanges 45 and 52 of the members 43 and 51 and liber washers 5o and 57 are mounted on each side of that leg of the U-shaped member. The parts are all clamped together by the nut 54 acting on the spring 53. These' overl-ranging ears 58 and 59 and a cam recess 6i) betweenv the ears. In releasably connecting the member or bracket 55 and, hence, the face piece to the member 25 carried by the head piece, the diverging legs 26 and 27 arerreceived in the diverging overhanging ears 58 and 59 andV the cam projection 31 on the leaf spring 30 is receivedin the cam recess 60 on the member 55. The diverging legs 26 and 27 and the diverging ears 58 and 59 secure the two members 25 and 55 together and they are releasably held in this position by the cam projection31 acting. in the cam recess 60. The lugs 28 and 29 operate tov limit the relative movement between the members 25 and 55. 'In this way -the parts are securely connected together so that the face piece `is firmly held upon the head piece. To release this connection all that is necessary is to separate the members and 55 against the laction of the leaf spring and this may be readily done merely by-eXerting adequate force for this purpose. Accordingly, the connecting means between the `face piece 1-3 and the head vpiece 10 includes frictional pivot means for permitting pivoting of the face piece with respect to the head piece and releasable connecting means for releas'ably connecting the face piece to the head piece.
Referring nowto Figure 8, the head piece is shown in the form of an adjustable head band having its ends received in a sleeve 66, the ends being adjustably clamped together in the sleeve 66 by a vclamping nut 67. A trans` verse band 68 'may be connected across the head band 65'. The head band 65 'carries a pair of members 25 which may be secured in place thereon by rivets. The members 25 are the Same as the members 55 secured to the hard hat -10-and operate in the same manner.
Referring now to Figures 2 to 9, the face piece is shown in the form of a welders face shield 14 having a shield 70 formed of compressed liber or the like which in turn is provided with a sight window 71. The face shield 70 may also carry a chin rest 72. A pair of U-shaped brackets or members 55 are pivotally secured to the face piece 14 in the manner described above in connection with Figures 3 -to 6. This U-shaped member 55 is the same as that described above and operates in the same manner. Figure 2 illustrates the welders face shield 14 releasably connected to the head band 11, but it may :also be secured to the hard hat 10, if so desired. Likewise the face shield 13, if desired, may be releasably connected to the head band 11 instead of the hard hat 10.
Referring now to Figure 11, the face piece is illustrated as taking the form of a pair of goggles 15 which may be utilized for Welding, chipping or the like. These goggles may take the form of the goggles illustrated in R. L. Malcom Patent No. 2,502,162. They include a pair of lens boxes `'connected together by a bridge member 76 and provided with suitable lenses 77. Temples 78 secured to the klens boxes 75 are slidably received in tubes 79 which in turn are pivotally connected as indicated at 80 to a pair of brackets 55. These brackets 55 are the same as the brackets 55 discussed above and function in the same manner. Here, the head band 12 is the same as the head band 11 described :above with the exception that the cross piece is omitted. Accordingly, like reference characters for like parts have been utilized. The head band 12 carries a pair of members 25 which are the same as those described above and operate in the same way. Accordingly, the goggles 15 are pivotally and releasably connected to the head band 12. In accordance with this invention the goggles 15, if so desired, may bereleasably connected to the hard hat 10 or the head band 11.
While for purposes of illustration one basic form of this invention has been illustrated, 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.
