7 Claims.

My invention relates to welders helmets.

This application is a division f the co-pending application of Marshall N. Anderson and Melvin H. Sellstrom, Serial Number 496,106, filed July 26, 1943, now Patent No. 2,410,256, October 29, 1946.

In operations involving welding and in similar operation-s, it is at times important to protect the face and eyes. At times protection of the eyes only is required, while at other times it is necessary that the entire face be protected. In welding, the change of conditions from those requiring complete face protection to those requiring eye protection only may occur frequently and at short intervals and for comparatively brief periods. As one hand of the operator is generally occupied in holding a torch or other implement, it is desirable that means be provided whereby the change from complete'face shielding to eye shielding only, and vice versa, may be accomplished quickly and conveniently by the use of one hand only. 7

One of the objects of my invention is to provide a welders helmet in which this change may be accomplished easily and quickly by the use of one hand only.

A further object of my invention is to provide a welders helmet having a face mask and an auxiliary eye shield in which the movement of the face mask from shielding position to nonshielding position will automatically cause the eye shield to move from nonshielding to eye shielding position.

A further object of my invention is to provide an improved adjustable eye shield for use in a welders mask.

Further objects and advantages of the invention will be apparent from the description and claims.

In the drawings, in which an embodiment of my invention is shown,

Figure 1 is a side view of a weldershelmet,

. part elevational and part sectional, the section being substantially on thelinel-I of: Fig. 2;

Fig. 2 is a vertical sectional view, substantially on the line 2-2 of Fig. 1;

Fig. 3 is a detail plan view on a smaller scale showing the mounting for the eye shield; and

Fig. 4 is a vertical sectional View substantially on the line 44 of Fig. 3.

The construction shown in the drawings comprises a headband or harness a face mask 2 pivotally carried thereby and movable from face shielding position A to a position B above the face, an eye shield 3 pivotally carried by said band and movable from eye shielding position C to a position D above the eyes, and transmission between said mask 2 and eye shield 3 whereby, when the harness is in place on the head, motion 0f the mask from shielding position A to nonshielding position B above the face will move the eye shield from nonshielding position D to shielding position C, and whereby motion of the mask from nonshielding position B to shielding position A will move the eye shield from shielding position C to nonshielding position D above the eyes. The mask may, in general, be of the construction disclosed in the patent to Anderson No. 2,270,028. I

The mask 2 is pivotally mounted on the headband I by means of a pair of pivot bolts or screws 4, nonrotatably secured to the mask and rotatable in bearing brackets or straps 5 secured to opposite sides of the headband by means of fasteners 6. Each pivot bolt 4 is rigidly secured to the mask by means of a pair of nuts 1, one on each side of the sheet material used in the mask,

the outer nut being tightened up to grip and clamp the sheet material of the mask between the two nuts.

In order to provide a frictional engagement for holding the mask and headband in adjusted position,.a coil compression spring 8 is provided acting between a pair of washers 9, one of which bears against the nut 1 and the other of which bears against the mounting strap or bracket 5.

The eye shield 3 is pivotally secured to the headband I by means of a pair of rivets l0 extending through a pair of pivoted L-shaped rock arms II on Whichthe eye shield 3 is mounted;

The construction by means of which lifting of the mask causes lowering of the eye shield, and vice versa, comprises a pair of brackets ;or arms l3 rigidly secured to the pivot bolts 4, respectively, each providedwith a crank pin or follower M which operates in a slot 15 on the L- shaped roekarm which carries the 'eye shield 3. In considering the effect of raising and. lowering the mask on-the movement of the eye shield, it should be noted that the pivot bolts 4 are fixed with respect to the mask 2 and that the crank arms l3 andcrank pins l4' rock with the mask 2 and pivot bolts 4. From this, it follows that the rocking movement of the crank pins M which slide in the slots [5 will cause a rocking action of the L-shaped rock arms H which carry the eye shield in such a way that when the mask 2 is raised the eye shield 3 will be lowered, and that when the mask 2 is lowered the eye. shield 3 will be raised. The crank arms I l and l3, crank pins [4, and slots l5 are so proportioned and designed that when the mask is pulled down so that the chin strap or rest l6 rests on the chin, the eye shield 3 will be raised above the eyes and away from the; sight openings. 17 tin-the mask itself andso that when the mask is raised to position B, so as not to be in front of the face, the eye shield will be lowered to a position C in front of the eyes to protect the eyes of thewearerr The operation of raising and lowering the mask and lowering and raising the eye-shield canzbe accomplished by gripping .the lower. portion. ofthe mask with one hand only and moving it to the desired position, leaving the other hand free.

The pivot pins 4 which carry the: crank. anns l3 may be firmly secured in. any desired position of rotary adjustment with respect to the :mask

Further modifications will be apparent to those skilled in the art and it is desired, therefore, that the invention be limited only by the scope of the appended claims.

Having thus described invention, what I claim and desire to secure lei/"Letters Patent is:

1. An eye shield comprising an arcuate supporting band, a transparent eye shield, and

.meansfor adjustably securing said eye shield to said band comprising means for securing one .endzoftheshield to: one end of the band, means for :detachably' securing the other end of the shield to theotherend of the band, an inter- \ilith a positioning element and an intermediate :portionrof:saidshield being provided with a plu- :ralityzoipositioning elements selectively engage- 2 by loosening the nuts I, adjusting thepins 4 rotarily with respect to the mask and again tightening up the nuts. This enables the crank pin- 1'4 "to be set in any position desiredwithre-- spect to the mask 2 to change the range-of movement of the eye shield- 3 with respect to the range of movement of the mask 2.

The eye-shield com-pri'sesa semicircular band orstrap [8 of flexible materi-alyriveted atl-Q to the L-sha'ped'mck arms- H and-asomewhat crescent shaped shield 28 of-flexible transparentmateri-al detachably secured to the semicircular strap.

In order to adjust the shield for different wearersor for different situations, means are pro vided for securing the transparent shield 20 in. difierent positions of adjustment on the semi circular ban-d. For this purpose, as shown in Figs sand-4, oneor both ends-oi 'the shield-are providedwith snap fastener pockets or eyes 2!,

similart'o glove fasteners, for engagement withcooperating snapfastener buttons Z Zonthe semicircular "band i8. The centralportion of the transparent shield is providedbwith a plurality of eyes or depression-s 2-3; any one of which may be brought into engagementwith a cooperating button 24 secured to the central portion ofthe band I8. To change the adjustment, one of the eyes '21 is disengaged, the eye23 on the transparent shield is disengaged from the button- Mon the strap and a different pocket 23 brought into registration and engaged with the button on the-strap, and the glove fastener-eye 2| is againsnapped into engagement with the cooperatingbutton 22 on the semicircular strap. The lower central portion of the eye shield '3' maybe cut away, as indicated at 25* in Fig. 2; andmay have a raised portion 26-, asyshown' in Fig; '1, toprovide clearance for the nose of the wearer when the shield-is brought'down into shielding; position.

As described above, the-crank pin 14 .may be set in any desired position with respect to the mask 2* to change the range of movement of the eye shield 3 with respect to the range of movement oi" themaskz. The i-ndivirsl-ualv wearer canadjustthe helmet by looscningup thernuts l,
