L. LIEG WELDERS MASK April 29, 1947.

Filed March 26, 1945 ZED 4/56 Patented Apr. 29, 1947 UNITED STATES PATENT OFFICE WELDERS MASK Leo Lieg, Clintonville, Wis. Application March 26, 1945, Serial No. 584,844

3 Claims.

This invention relates to improvements in welders masks and more particularly to a novel mask having an automatically operable eye protecting shield.

I am familiar with the fact that eye shields have been provided in conjunction with welders masks when the latter are pushed upwardly above the face of the wearer, but in the devices in present use, the eye shield must be moved manually to the position desired. When the welders mask is down it is preferable that the eye shield be raised out of the line of vision. The necessity for moving the eye shield and the mask proper in separate manual operations slows the work of the operator, and it; is one of the objects of this invention to provide a welders mask including a conventional light filter and a separate eye shield which will be withdrawn upwardly automatically when the mask proper is pulled down before the welders face.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawings, in which:

Fig. 1 is a view in vertical section of a welders mask embodying my invention.

Fig, 2 is a similar view of the device with the mask proper turned upwardly in the out of use position.

Fig. 3 is a plan view partly in section and partly in elevation showing the friction detents for raising the transparent eye shield.

Fig. 4 is a front view partly in elevation and partly in section.

Referring more particularly to the drawings,

the numeral Ill refers to the device generally, having the conventional mask l [provided with the light filter glass l2, the longitudinal head band l3 and the transverse head band l4. Buttress straps [5 and I6 are secured to the transverse head band I4 by means of the rivets I1, l8, l9 and 20.

The transverse band 14 is secured at its ends to the longitudinal head band 13, as by means of the rivets 2| and 22.

The head bands I3 and I4 and the buttress straps l5 and I6 retain the pivot members 23 and 24 which comprise the pivot points for raising and lowering of the mask ll, to bring it away from or into the line of vision of the user as desired.

Forwardly of the longitudinal centers of the band [3 and fixed thereto, are the pivot members 2'! and 28, on which is pivoted an arcuate band 29 carrying a conventional transparent eye shield 30, affixed thereto by means of male and female snaps at 3|, 32, 33 and 34. The band 29 has integral, tangentially extending arms 35 and '36 2 oppositely disposed with relation to the pivot members 21 and 2B. The arms and 36 have outwardly directed frictionaldetents 3! and '38 contacting the inner side walls of the mask II.

In use, the operators action in pulling the mask i l down to bring the filter glass I2 into his line of vision will cause the inner surface of the mask H to frictionally engage the

detents

31 and 38 causing them to move downwardly thus raising band 29 with the eye shield 30 upwardly out of the line of vision. When the mask H is raised to its retracted position above the line of vision of the wearer, an opposite action will lower the eye shield 36 into the use position within the line of vision.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:

1. In a protective mask, a supporting head band, a pivoted face shield thereon, an auxiliary frontal band, pivot elements mounting said auxiliary band and spaced forwardly symmetrically of the mid-points of said head band, and tangential lever members integral with said auxiliary band and extending rearwardly and outwardly from the pivot elements and bearing frictionally against the inside of said face shield.

2. In a protective mask, a supporting horizontally disposed head band, a pivoted face shield thereon, an auxiliary substantially semi-circular frontal band, pivot elements mounting said auxiliary band for arcuate movement and spaced forwardly symmetrically of the mid-points of said head band, and tangential lever members integral with said auxiliary band and extending rearwardly and outwardly from the pivot elements and bearing frictionally against the inside of said face shield.

3. In a protective mask, a horizontal head band, a face shield pivoted thereon, an auxiliary frontal band exteriorly of said head band, an eye shield secured to said frontal band, pivot elements mounting said auxiliary band and spaced forwardly symmetrically of the midpoints of said head band, tangential lever members integral with said auxiliary band extending rearwardly and outwardly from the pivot elements, and exteriorly rounded projections adjacent the ends of said levers in frictional engagement with the inside of said face shield whereby when the latter is lowered the transparent eye shield will be raised above the line of vision and vice versa.
