This invention relates to awelders hood,

The primary object of this invention is the provision of an improved welders hood preferably constructed of soft, flexible material, such as leather, providing features of comfort and utility to the wearer not hitherto known.

A further important object of this invention is'the provisionin a welders hood of means to preclude the frosting over of the window thereof, such as mi gh't be; occasioned by thebreath of the user. 1

An additional important object is the provision of means in' association with a welders helmet which completely surrounds the head, whereby the wearer thereof may breathecomfortably and :naturally without-danger of inhaling particles or fumes given off by the welding arc.

Still another. object is the provision of a welders hood which may be readily retained in positionat all times regardless of the position of thewea'rer thereof. T

A still further object is the provision of a flexible 'welders'helmet which completely surrounds thehead of the user and protects and covers completely areas of otherwise exposed skin, thus protecting the wearer not only from his own arc but from the arc of adjacent welders as well.

Still another object is the provision of such a helmet which may be readily adapted to various sizes of heads, in such manner to be worn with the maximum of comfort and efficiency.

Still other objects reside in the combination of elements and arrangement of parts and features of construction, all as will be more fully pointed out hereinafter and disclosed in the accompanying drawings wherein there is shown a preferred embodiment of this inventive concept.

In the drawings Figure 1 is a front elevational view of one form of helmet embodying features of this inventive concept.

Figure 2 is a fragmentary elevational view of certain features of the helmet disclosed in Figure 1 as seen from the interior of the helmet.

Figure 3 is a sectional view taken substantially along the line 3-3 of Figure I viewed in the direction indicated by the arrows, the flap being omitted in this View and Figure 4 is an enlarged rear elevational view of the constructional details adapted for adjusting the size of the helmet, parts being broken away and omitted.

Like reference numerals refer to like parts throughout the several views of the drawings.

Having particular reference now to the draw- 3 Claims. (Cl. 28)

ings, there is generally indicated at H] a welders helmet, preferably constructed of heavy, relatively pliable material, such as leather, and provided with a front'skirt II and a rear skirt l2, adapted to depend well downwardly about the neck and over the chest and back of the wearer thereof. I

The helmet is provided with an eyepiece generally'indicated at l3, consisting of arelatively heavy rectangular frame I4 secured in an aperture at the front of the helmet [0. The frame 14 has'an interiorly positioned pane of clear glass l5 adjacent the helmet and has an extendingi portion l6- hinged as by hinges i] to the 'frame-meinber'ldp The member 16 has positioned therewithin a'pane of relatively dark glass "[8 adaptedto protect the eyes of the welder from the 'glar'e' andultraviolet' rays emanating from thewelding torch. A spring l9 positioned back of "darkened glass pane I8 is "adapted to secure the parts in related assembly. As best shown in Figure 1, extending portion N3 of frame 14 is provided with finger grips 20 whereby the'frame may 'b'eraised to provide clear visionthroughithe injter'ior pane l5 when the device is not in use. "A soft leather flap 2| fits as at 22 in front of helmet l0 and is adapted to overlie and protect the hinges l1 against damage or injury from molten metal or the like thrown off by the welding torch.

The helmet is adapted to be supported in such manner that the weight of the frame l4 does not bear against the wearers nose, as by means of a roll 25, of sponge rubber, soft leather, upholstery welting or the like, which is adapted to rest against the forehead of the user directly above the eyes and support the weight of the frame and its associated glass pieces.

Hitherto one common dificulty with welders helmets has been the fact that the breath of the operator has a tendency to rise upwardly and cloud over the glass eye plate. This difiiculty is overcome in the instant invention by the insertion of a sheet or piece 26 of fleece, soft leather, sponge rubber, or the like, secured at an edge, as at 21, peripherally about the front of the helmet I0 and adapted, through its natural resiliency to flare inwardly against the face of the operator, above the nose and mouth but below the eyes, in such manner that vision through the eye piece is unimpaired but the passage of breath from the nostrils or mouth upwardly to the eye piece is substantially precluded.

Means are also provided to facilitate the breathing of the wearer of the helmet, in such manner as to preclude the ingress of flame or particles thrown out by the welding arc. Such means take the form of a channel or tunnel 30" comprised of relatively stiff leather, of a consistency suificient to maintain its shape, and se- 7 cured as at 3! and 32 (see Figure 3) adjacent a' plurality of openings or apertures 34 in the front pass from'the rear of the wearer through the tunnel to the mouth and nostrils.

welder changes position, that is to say, head out of the vertical for any reason, is precluded. v
