FIREMANS MASK.

SPECIFICATION forming part of Letters` Patent No. 702,481, dated June 17, 1902.

Application filed September 2'8, 1901. Serial No. 76,923. (No model.)

To @ZZ whom it may concern: of the head, as shown in Fig. l, and with an- Beit known that I, JAMES BUTLER REID, a other elastic 4, connected at one end with citizen of the United States, residing at Glovthe upper edge of the mask, as at 5, and at ersville, county of Fulton, and State of New the other end with an elastic 3 to pass over 55 5 York, have invented certain new and useful the top of the head for the purpose of hold- Improvements in Fire-Masks, of which the ing the mask upon the face of the wearer. following is a speciiication; The body of the mask is shown in the form The invention relates to such improveof an inclosure consisting of the sheets of ments; and it consists of the novel construcmaterial G and 7, secured together along their 6o Io tion and combination of parts hereinafter deedges by rows of stitching 8. When desired, scribed and subsequently claimed. the inner sheet may be covered by lining 9, Reference may be had to the accompanying formed of softer material, coming in contact drawings and the referenceeharacters marked with the face.

The inner sheet7, as shown in Fig. elevation of the exterior of my improved ire- 4, may be of sheepskin dressed with the wool 7o 2o mask as the same appears in use, the head of 10 thereon, which serves as a filtering matethe wearer being indicated by dotted lines, rial. The outer sheet of material may be shown on a smaller scale than the other igmade of leather or other material which will ures. Fig. 2 is a front plan view of the mask not readily admit of the passage ofv smoke laid out fiat.

The inner sheet of the walls of the mask-inclosure laid out flat, material or wall of the inclosure is provided with a portion of the attaching projections with a central aperture 13,' adapted to receive So 3o broken away, showing a modified form of the nostrils ofV the wearer, whereby smoke construction.

The eye-aperture is also closed through the filtering-chamber by means of a fiexible tube 20, the outer end of which is secured to the outer wall ot' the inclosure, as by stitching 21, and the inner end to the inner wall, as by stitching 22, thereby wholly shutting off the eyes of the wearer from the smoky atmosphere without the mask and also from the filtering-chamber, which aords absolute protection to the eyes and permits free access of the visual rays to the eyes. When desired, the tubular connection 2O may be dispensed with, as the smoky atmosphere could not reach the eyes except through the filtering material in the inclosure.

The flexible nature of the connecting-tube permits the-mask to be easily bent and the inclosure compressed to more readily fit and conform to the shape ofthe face ofthe wearer.

When desired, the mask can be made of concavo-convex form, as shown in Fig. 7. The sheets of material forming the inclosure are cut to provide the gore-openings 25, 26, and 27 in the edges of the inclosure-walls, as shown in Fig. 5. The edges of the gores are brought together and stitched to each other, as by the stitching.r 28, as shown in Fig. 6, thereby giving the inclosure a concavo-convex form, as shown by the cross-sectional view in Fig. 7. This form causes the mask to more tightly fit the face of the wearer at or near the edges of the inclosure. In this modified form of construction I have also shown a central aperture 29 large enough to receive both the nostrils and the mouth of the wearer, and the eye-apertures are also made slightly larger in diameter.

It is obvious that the mask-inclosure may be made of such a shape as to cover the nostrils and mouth without covering the eyes, although I prefer to provide the mask with protection for the eyes as well as the respiratory organs. y

I do not desire to be limited to any kind of material for the inclosure-walls, provided the inner wall or covering, which comes in contact with the face, is of such a yielding nature as to conform to the irregularities in the contour of the face, so as to exclude smoke and air from the respiratory organs, except such as passes through the filtering material in the filtering-chamber.

The filtering material may be either integral with one or both of the inclosure-walls or it may be of a different texture. It may also be made of mineral substances, as mineral wool, or of any material which would act as a filter to separate carbon and other impuricentrally of the mask the admitted smoke and air are caused to travel a longer distance through the filtering material than they would it' the smoke and air Were admitted through a central opening opposite to and nearer the respiratory organs. By having the visual tubes pass entirely through the filteringchamber the eyes are wholly protected from smoke, not even coming in contact with the filtered smoke.

What I claim as new, and desire to secure by Letters Patent, is-

1. Afire-mask, comprising a fiexible inclosure, containing filtering material, open to the atmosphere at or near its outer edges to admit smoke and air, and near its central portion to admit the nostrils ot' the wearer, and having eye-apertures therethrough, closed at their outer ends to the atmosphere by a transparent coveringimpervious to the smoke, and means for securing the inclosure upon the face of the wearer.

2. Are-mask, comprising a fiexible inclosure, containing filtering material, open to the atmosphere at or near its outer edges to admit smoke and air and near its central portion to admit the nostrils of the wearer, and having an eye-aperture therethrough, closed to the filtering-chamber by a tube and to the atmosphere at their outer ends by a transparent covering, and means for securing the inclosure upon the face of the wearer.

3. A fire-mask, comprising a concavo-convex inclosure, containing filtering material, open to the atmosphere at or near its outer edges to admit smoke and air, and near its central portion to admit the nostrils of the wearer, means for admitting visual rays to the eyes, and means for securing the inclosure upon the face of the wearer.

4. A fire-mask inclosure, comprising two sheets of material secured together around their outer edges, containing filtering material integral with one of such sheets, open to the atmosphere at or near its outer edges to admit smoke and air, and near its central portion to admit the nostrils of the wearer, means for admitting visual rays to the eyes, and means for securing the inclosure upon the face of the wearer.
