. Be it known that 1, JAMES .T. BRAYTON, a. citizen of the United States, residing at Chicago, cpunty of Cook, State of Illinois, have invented a certain new anduseful Im- I f provement in Protective Masks for. Workand declare the following to be a full,

such

a "aswill enable others skilledinthe art to which it pertains to make and use the same,

, referencef being had to theaccompanying f I of the apparel of the great multitude of workmen who need protection.

The object of my invention is to produce a. simple and novel device for protectingthe face or parts. thereof against light, heat, dust or flying" missiles, which will permit the yw'earerto work in the presence of poisonous gase'swithout being in ured; whichshall be 530 so light as" not tobe a; burden but be entirely comfortable .to the wearer; and which may I be"ad 'usted, when removing it, so as toleave the entire face ofathe wearer exposed.

" ,The various features of novelt. whereby my invention is characterized will hereinafter be pointed out with'particularity in the claims; but for a full understanding ofiny invention and of its object and advantages,

to be put. For the sake ofbrevity, I have shown only a few simple constructions among which are embodied all of the essential .features'required to take careof the various conditions to which I have heretoifore referred. It will of course: be understood that. where device is to be'usedonly for aparticular purpose, it need .not bemade toembody features. other than'those'necessary to fulfil the intended purpose.

Referring to Figs. 1 and 2, 1 represents a maskor shield. large enough to ico ver the eyes, the noseand the cheek bonesof the wearer, being preferably made of'soine light stiff materialsuch as aluminum orjtough non-inflammable fiber .bent or pressed into the proper shape. In the arrangement shown, the central portion, 2, of the mask or shield is shaped to extendover the nose and beneath the same to the vicinity ,ofthe upper lip, the part 2 projectingoutwardly-iron.

the wings which extend over thezeyes and cheek bones. The wing portions of the mask or shield are provided with suitable lenses,

3, which may be mounted in cups, 3, arranged upon outwardly pressed panels, 5, extending .laterally from the sides of-tlie nose piece. This arrangement permits the lenses to be held far enough away from. the face to clear the eyelashes and at the same time, prevent the heat of the lenses, in case they become hot, from affecting the eyes. .Thec'ups may be shaped in the manner described in my. ap-

plication for improvements in goggles exe- 'cuted of even date herewith, wherebythe lenses are brought close't'ogether and the field "of vision toward the'front is not obscured.

The mash or shield is preferably hinged to a suitable headband, 7, which may be a fastenedtogether by lacings, '8, which permit it to be adjusted about. a head of any size.

The parts aregso proportioned thatthe mask or shield may either be swung down in the.

position indicated in Fig. 2 'or'it'may be' swung upwardly about its hinged "joints so as to lie on top of'fthe head andout'of'the Way.

Where the faceof the workmanfisto' be protected against heat. or light rays, only,

the parts that I have just described are all that are necessary to give adquatefprotec- "tion. If the-workman must work in the presence of poisonous gases or in a dusty atmosphere, additional protection is desirable. Thus the shield may be provided on the side next to the face with a cushion, preferably in the form of a pneumatic tube 9, so disposed that it will extend across the forehead of the wearer down over the cheeks and beneath the nose and thus form a reasonably tight seal between the mask or shield and the face. The pneumatic tube may be 1nflated in any suitable way as, for example, through a suitable nipple, l0, placed at any convenient point. In order to provide the workman with pure air, an air supply plpe 11, is led into the upper portion of the nose piece 2 so that fresh air may be supplied 1nto the closed chamber between the shield or mask and the face. The air tube may be provided with regulating valves of any suitable type, there being in the illustration only a single valve, 12, within eas reach of the workman. The air tube is pre erably arranged to pass up over the head and down the back where it may be attached to a suitable supply of compressed air carried in a receptacle on the workmans back or to a pipe leadin r to any suitable remote source of supply. t will be seen that with this arrangement air under any desired pressure may be supplied, so that the workman may breathe pure air regardless of the condition of the surrounding atmosphere. Furthermore, by supplying an excess of air, there will be a constant leakage of the same beneath the pneumatic cushion so that the face of the wearer will be kept cool and any poisonous gases or dust which might tend to enter through crevices left between the cushion and the face would be forced outwardly. Consequently, this simple arrangement permits a. workman to enter a chamber completely filled with poisonous gases and to work in entire safety and comfort.

The discharge end, 11, of the air inlet pipe is preferably so arranged that it will cause the incoming air to travel laterally over the inner faces of the lenses and thus .keep the lenses free from moisture. Where the device is to be used in the presence of dust, the outside of the lenses may be kept clean by rgviding the nose piece of the mask or s ield with narrow slots, 13, disposed at the inner edges approximately in the plane of the lenses, so that some of the air will flow out across the lenses and blow away any dust which may accumulate thereon. With this addition the shield or mask permits the workman to be employed in, an extremely dusty atmosphere without male ing it necessary for him to breathe dust or be inthe least uncomfortabllg, and without fear that his vision will be obscured by reason of dust collecting on the lenses.

If desired, the hiad hand 7 may he at-' tached to or forml art of a skull cap, 14, which will serve to qover the top of the head of the wearer and, if desired, skirts-14, of any desired material may extend down from the head band or skull cap so that, with the remainder of the parts, the entire head and face, except the mouth and a part of the chm will be covered; the skirts being fastened under the chin with any suitable fastening devices as indicated at 15 and being tucke into the collar of the shirt, coat or blouse of thie'wearer. lVith this arrangement the wcareris completely protected against dust and dirt,

, Insome lines of work, such as sand blasting, where steel shot are mixed with the sand, it is desirable that the lenses be protected against the rebounding shot and the sharp sand For this use, an auxiliary apron may be provided as indicated at 16 in F ig. 3; this apron being of any suitable materia preferably flexible, and extending down from the top of the mask or shield to a point below the lower edge, of the same and preferably far enough down to permit its lower end to be tucked into the collar of the wearer. That portion of the apron just in front of the lenses is made of gauze or slitted metal so that the apron contains a panel, 17, which does not obstruct the vision of the wearer but does protect the lenses against flying sand and shot. The lower portion of the apron of course rotects the mouth and chin of the wearer. T nected to the mask or shield in any suitable way; being, if desired, secured by means of detachable fastenings which will permit it to be attached and detached at will.

he apron, 16, may be con In Fig. 4 I have illustrated the simplest form of my invention in which the mask or shield 20 consists of a simple piece bent into the same general shape as the mask or shield heretofore/described, but having the bottom of the nose piece, 21, open. The mask or shield is hinged to a head band, 22, at its upper rear corners and having an inwardly projecting lip, 23, at the center of the top, 'lllClf 11 3's "adapted to rest upon a finger or projection, 24, on the front of the head band and thus prevent the mask or shield from swinging too far down. In other words, the mask or shield is supported entirely from the hinges 25 and the lip 23, making no contact with the. face of the wearer and therefore being cool and comfortable. lrVhen the mask or shield is not in use, it is. simply swung back about its hinges and on top of the head.

There is another featureof my inventim which may be of considerable importance.

The eyes of workmen exposed to intense light, such as workmen employed in electric arc welding may be protected against the intense light by using properly colored glass in the lenses of the mask or shield. In the same way protection may be given to the eyes against injurious invisible light rays by making thelenses of a properlyprepared glass containing lead, bismuth, barium or some oftheir compounds. 1 The mask or shield, including the skull cap and the curtains may be coa'tedwith suitable paints containing lead bismuth or barium and compounds so'that the entire -head and face of workmen engaged in eleetric'welding or other work? 1n which X-rays. ultra-violet rays and other deleterious rays are given off.

will be completely protected. The same ex-.

pedien't may of course be adopted in connection with gloves and other clothing of the workman so that his entire bodywill.
