Dec. 23, 1947.- I R. T. SHIELDS WELDERS HELMET Filed June 12, 1945 Patented Dec. 23, 1947 UNITED STATES PATENT OFFICE WELDERS HELMET Raleigh T. Shields, Newport News, Va. Application June 12, 1945, Serial No. 598,963

This invention relates to a novel and improved welders helmet and more particularly to an eye protecting shield, its construction and method and means of mounting same on the helmet frame to satisfactorily achieve the desired ends.

Briefly, the preferred embodiment of the invention is characterized by an endless circular band to embrace the head and temples of the wearer, this being attached on opposite sides to the helmet, there being a pair of suitably shaped arms hingedly connected at their rear ends to corresponding portions of said band, and these latter arms being attached to an appropriate eye protecting shield which can be conveniently swung down when in use, or swung up to an out-of-theway position beneath the helmet.

The principal object of the invention, obviously, is to provide a suitable welders helmet with an adequate type of eye shield which may be moved out of the way or brought into position whenever necessary or desired depending on the circumstances, said shield serving to protect the eyes against the flying hot flux and metal, and also from the arcs of other welders nearby.

Other objects, features and advantages will become mor readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

'Figure 1 is a side view showing the eye shield equipped welders helmet as constructed in accordance with the principles of the instant invention and portraying the manner in which it is worn and used, a portion of one side being broken away to expose the structural details therebeneath.

Figure 2 is a fragmentary view showing a portion of the helmet on one side and bringing out the top plan and configuration of the head band and eye shield attachment, other parts being purposely omitted for clearness of emphasis of the main parts.

Figure 3 is a section which may be said to be taken approximately on the plane of the line 3-3 of Figure 2.

Figure 4 is aview somewhat similar to Figure 2, this bringing out, partly in perspective, the shape and formation of the details.

Figure 5 is a view which may be said to be taken approximately on the plane of the line 55 of Figure 1 bringing out the parts on a larger scale.

Referring to the drawings by distinguishing reference numerals, the helmet, which is of ap- 4 Claims. (01. 2-8) propriate shap and materials is denoted by the numeral '1. This preferably conforms to the shape and size of a regular welders helmet and is positioned to extend out so as to provide clearance space between itself and the forehead to accommodate the eye shield, permitting same to be raised and pushed up under and between the helmet and head when not in use, or brought down to the useful position illustrated in Figure 1. In

order to achieve the desired ends, I employ a substantially circular slightly downwardly and cut wardly slanted band or adapter 8. This surrounds the head as shown and also embraces the temples of the wearer, the opposite median portions thereof being pinned, as at 9, to adjacent edge portions of the shell of the helmet. Either a bolt or a screw may be mployed, this as brought out in Figure 5, the same being surrounded at inner and outer end portions by short spacing sleeves l0 and H. The numerals l2 designate. outstanding stop or rest pins carried by the band 8 which are of appropriate dimensions and shape and these accommodate the horizontal reaches or portions of the duplicate eye-shield arms l3. The rear or inner ends of the arms 13 are formed into suitable eyes l4 hingedly mounted on the pins 9 on opposite sides of the helmet. When they arms are down, that is in horizontal and useful positions as seen in Figure 1 they rest on the outstanding stop pins which pins serve to keep them in the thus elevated position. The outer ends of the arms are directed laterally and downwardly.

as indicated at l5 and they are then attached as at Hi to a substantially arcuate channel-shaped frame member I! which carries the detachable eye shield I 8. This is of appropriate fireproof transparent material and, in practice, may be suitably colored, for instance colored green for restfulness to the eyes of the wearer.

When it is not necessary or desired to utilize the eye shield 18 in a position in front of the wearers eyes it can be swung up to an out-ofthe-way position. That is to say, the user can simply grasp the eye shield and lift it up by hand and then move it to a position over the top or crown of his head in which position it takes a horizontal setting. Also, if the visor or helmet l is at the same time in a correspondingly horizontal position, the eye, shield I8 takes a position between the helmet and the head of'the wearer. When the eye-shield I8 is in this up and out-ofi sumed that there is a single latch under consideration. Each latch is of the construction shown in Figure 5; that is to say, it comprises a slidably mounted pin having a knurled finger grip which is accessible through and beyond one side of the helmet, the shank of the pin being slidable in an aperture in said helmet. The pin is held in normally projected or locking position by a coiled spring 2| bearing against a suitably arranged; istop shoulder 22. When: the arms l3 and companion eye-shield llFareboth-downand the face shield l is simultaneously down (see dotted lines in Figure 1), the latch pin I9 is their. snapped into the aligned keeper slot 23-. With. both shields 1 and I8 latched together they may be swung conveniently up and over the=wear.ers:i: head to assume outof-the-way,. positions. Also,, said shields may be operated and used independently; that is, the shield I may be shoved inland: self retained over the wearer's head, while the other shield] 8. may; be. droppeddown for use, as shown in full .lines in. Figure ,.1.. By the same token, .and. assuming thattheshild] isup and. the.us.er;wants to lift the eyeeshield l 8 and locate samebetweenthe shield I andthe top of. hishead, this too can-be accomplished and saidshields again..latchedtogether. for proper. maintenance.

The gist .of- .the invention is..in .the. provision. of- -a comfortably and. appropriately shaped helmet, this toaccommo'data. by suitable clearance, the. .circular headland adapter. b'and,'..the .latter assisting .in supporting the helmet'in place, also. serving asan eife'ctive complemental part. for the opposed pairs of arms. whichiserve in turn, to suspendand hingedly mount the arcuate eye shield.

With furtherrreference to the aforementioned springpressed latches. or .detents l9, it will. be observed that whenthe helmet I swings-up. and. overthe head. and assumes a horizontal position as illustrated-in} Figurel, it will. carry the eye. shield I8..up:with'. it. In. other. words, the eye shield .willmaintainthe same spaced parallel relation..to the helmettand jboth. parts will swing up. as. .a..unit. However, if .it is desired, the helmet can. be released. by disengagingthe latch and swung .up independently leaving ,the eye-shield in.the down positionshownin fulllines .inFlgure 1-.. Then. when thehelmet is returnedtoits normal...face .shieldingposition. as. shown. in dotted lines-inFigurel, the latch. I9Twillhave to be reengaged withthe-keeper slot 23.. These are, how ever, obvious phasesof the invention suchlas will, be .clearto: persons skilled .in .the, .art to. which it relates.

In. practice. I.- contemplate .using either one or. two. of..said latches. depending. on requirements of the .trade..

A- carefulaconsideration -of the foregoing; description in conjunction .withwthe, invention; as illustrated in.the.drawings wi1l1;enable'.- the reader to. ,obtain .avclear understanding and impression. of the allegedfeaturesof. merit. and noveltyysuf; ficienttoclarify the construction of'theinvention as. hereinafter. claimed;

Minor changes in. shape, size, materials: and rearrangement offparts maybe resorted to in actualpractice so,long as no departureis made fromthe. inyentionas. claimed.
