Description

Nov. 21, 1944. AF. D. HUNTSMAN WELDER S MASK Filed March 29, 1943 AITDRNEYS Patented Nov. 21,y 1944v Y f PT escaner This invention relatesgto masks. forv Welders and the like, and its general object isjtoprovide anI attachment for the mask,l that is designedl and associated with the headbandsA thereof, 'for disposal in close proximity lto the eyes yof the wearer to protect the same fromfumea-.dirt ,andA

other foreign-matter,l the eye protector including,

a detachable transparent shield movable into anda' out vO f .eyeprotecting positionbut .casual move-4` ment or displacement from either position is practically impossible and the'protector in no way interferes withthe use of the mask or the movement thereof relative to its headbands.

A further object is to provide an eye protecting attachment for welders masks, that is simple in construction, inexpensive to manufacture,v and extremely efcient in` operationyuse and service. 'Y This linvention also consistsin certain other features of construction and in the combination and arrangement of the several parts, to be hereinaiter fully described, illustrated in the accompointed out in panying drawing and specifically the appended claim. j Y

In describing the invention in detail, referencewill be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side View illustrating a Imask ini cluding my eye protector, applied to a wearer, and with the maskand protector in use in full lines and out of use in dotted lines.

Figure 2 is a front view partially in section f and with the shield member of the eye protector removed from its-attaching band.r

Figure 3 is a detail sectional View taken vertilcally through the shield member and its attaching band, separated from each other, and illusf trates the fastening stud for the shield vmember in elevation. i p 1 l Figure 4 is a fragmentary side elevation, with the pivot bolt for the `mask and shield'member attaching band in section. y

lFigure 5 is a horizontal sectional View taken. approximately on line 5-5 of Figure 1.

Referring to the drawing, the mask I is provided with the usual head encircling band 2 having longitudinal and transverse supporting

straps

3 and 4 respectively. The strap 4 is formed from suitable resilient material and has its en d portions lbent upwardly to provide U-shaped loops,5 having registering openings therein. Pivot members 6 are disposed in theopenings of the loops 5, and the mask is pivoted thereon for swinging movement into and out of use, as shown in full and dotted lines in Figure 1. The outer portions df the/loops 5bearagainst the mask for holding the latter in'its respective positions. yThe pivot to the headband 2.and its medial portion connected to the strap 4.

HThe mask .I is ofthe Iusual `sheet metal construction .and includesa rounded body portion to cover the face andsdes oi the head, and an upper portion 'II to covervthe Aforwardportion of the head. The usual elongated opening is provided in the` front of the body portion and the opening is closed by a transparent panel 8 that is held inA placeby a frame 9. i

My eye protector includes a substantially semicircular or arcuate attaching band that is made up of a strip Il) Aoi" metal', having its ends piv'otally secured on the bolts k6 between' the inner portions ofv the U-shaped loops'5 and the head encircling band 2, to frictionally hold the eye protector into and out of use, as shownr in full and dotted lines in Figure l. The strip or member I0 isl of relatively thin spring material. It has, on its inside, near each of itspivotal points, a projection II. These projections have inclined or rounded surfaces aiorded by making the projections of approximately conical or somewhat dome 'shape. They may be formed by indenting the strip material from the 'opposite side.

Toward the front and beyond the projections I I, the strip I0 is bent outwardly as at I2 tov provide an arcuate portion I3 to be spaced a considerable distance forwardly of the band '2,' as likewise shown in Figure 5, and Xed to the front face of the arcuate portion I3 by rivets I4 is a strip I5 of iiber or thelike. The strip I5 is of a length coextensive with that of the arcuate portion I3'and secured to and extending through .of stud type snap fastener members II are` like- "wise secured to the strips I 0 and I5 for disposal upon the opposite sides of the stud I6, as best shown in .Figure 2.v y

The shield member includes a panel I8 of transparent material that is mounted in a frame f I9, that includes a straight at upper member 20 having an eyelet 2| centrally arrangedk therein for receivingthe stud I6, and the upper memberv i 20 adjacent its ends has Asecured thereto socket type fastener members 22 for receiving the stud members I 'I. By that construction, it will be obvious that the shield member is detachably se-r A @3GB-461i -eyeshield in that position.

cured to the attaching band, and such is clearly indicated in Figure 2. The lower portion of the shield member is rounded and centrally recessed as at 23 to provide a nose receiving space, so that the shield member can be disposed substantially in engagement with the face and therefore amply protect the eyes of the wearer.

When the mask is in protective position in front of the users face, the eyeshield usually is in the upper position and out of the line of sight. The projections I I, by contact with the upper edge of the carrying member I or headband 2, hold the When the mask is swung, or about to be swung, upwardly from in front of the face, the member I0 may be swung downwardly to bring the eyeshield to position in front of the eyes. During this movement, the project-ions I I ride over the edge 'of the headband and by frictional contact with the front or outer surface thereof keep the eyeshield in protective position. Spring or yielding properties of the member I0 permit this movement. When the eyeshield is returned to the upper position out of the line of sight, the projections II move olf the outer surface of the headband and resume contact with the upper edge thereof to retain the eyeshield in upper position. The projections II are shown in Fig. 1 adjacent to the upper edge of the headband and about to engage that edge upon slight further upward movement of the eye shield.

As movement of the eyeshield is not affected at all by the position of the mask, it also may be moved to protective position when the mask is down in front of the face. In some circumstances this is desirable; as, for example, when the eyeshield is of `colored material and a Welder is not afforded sufficient glare protection from a welding flame by the colored glass of the mask.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such Changes fall within Ithe scope of the appended claim.

What I claim is: y

In a face protective device :including a headband, an arcuate member of yieldable sheet material pivotally associated near its ends with said headband at its sides and swingable downwardly to and upwardly from position in front` thereof, an eyeshield mounted on and depending from the front of said member, and an inclined'surfaced projection on the inside of said member near one of its pivotal 'points contactable with the upper edge of said headband to hold up said member and movable over the edge of said headband to frictionally contact with the surface thereof on downward movement of said member.
