Patented Nov. 11, 1913. serial No. 784,949.

Figs. and 8 are detail cross sections taken on the lines 77 and 8-8, on Figs. 5 and 6, re-- spectively. Fig. 9 is a perspective View that illustrates the manner in which the.

vizor portion is folded into shape. 'Fi 10 is a perspective view of my appliance folded into its compact form to thereby adaptit for being carried in the pocket of the user.

In its practical arrangement, my improved breathing appliance comprises an upper or vizor portion shaped to cover the face of the user and a vpendent tube-like portion 10, the latter and the face portion being preferably of canvas or like material. The viz'o'r portion 1 has a pair of glazed sightopenings 2 that are suitably formed in the said portion and arranged in any well known manner to thereby prevent moisture a'ceuiriulating' Within the face covering and depositing on the inside of the glazed openin s; To hold the Viio'r portion that covers the face clamped against the head and under the chin of the riser, the front or edge portion of the said covering has an elastic 4 held Within the hem 5 0f the said edge portion (see Fig. 3).

By reason of fitting the tightly over the face as stated and shown, dutsi'de air is prevented from entering the ftice covering around the edges thereof.

For securely holding the appliance on the head of the user, a 'Wide elastic band 6 is provided, the ends of which'are stitched to the opposite s'l es of the face covering adent the openings; as is clearly shown in Figs. and "1. I

The dep'ohding air tube, which is gradually tapering toward the lower end, is prorifled at su'.. o'le intervels with annular i'ener or supporting rings 77, three of 1 rings h i shown, and these are or *"sii'elv d'u'c'ed diameter, the smallest hettonr These rings at all times hold the appliance is in use,

passage fof air to the user.

s'ev rral are each secured to the tube z unber of stitches 8, that are sewn through tht 'elltsidc the tube across the top and t t I W i of the rings. To further hold in plate, and at the same time protee tube open when for the free test the stitehes 8, an insulator tape covering face covering A and making the tube tapered, as stated and shown, when not in use,- the appliance can "be folded up into such a small compass that it may be readily carried in the pocket of the user, since the lowermost ring with that portion of the tube between it and the next ring can be telescopically moved into the next ring above and the said next ring and its tube portion above it likewise moved into the upper ring.

It will be seen that the rings may seat within each other and are annularly corrugated, as shown.

The uppermost ring 8 is of such a diameter relatively to the vizor portion thatin folding the said vizor portion down into the upper ring, the two eyes or openingscan be arranged fiatwise, side byside, down within the said upper ring and thereby be held secure against breakage when carrying the appliance.

The face portion of the appliance is folded down over the upper ring and the several portions that constitute the complete applianee are held packed .in a compact shape by the elastic head band which is held under; tension crosswise tightly over the package (see Fig. 10) by a half twist when snapping it over the said folded package.

From the foregoing description taken in connection with the drawing, the manner of its use and the advantages of my invention will be readily understood by those skilled in the art to which it appertains. Among other advantages it should be mentioned, since it can be conveniently carried in the pocket of the user, and the parts held together by the twisted elastic band, the user, a fireman,-for instance, in case of emergency, can quickly 'withdraw the package from his pocket and with the same hand quickly unsnap the holding band and thereby have the appliance in shape for quickly fitting the same for use.

The function of corrugating the rings 7,- as before mentioned, is to serve as a more positive retainer of the ring in its place on the canvas tube, it being readily seen that when the tape 9 is wrapped around as in Fig. 6, the tape being pliable, will tend to conform to the undulations of the canvas and ring beneathit, and so serve as a binder of the several thicknesses and also as an assistant to the stitches 8.

\Vhat I claim is: Q l. A breathing appliance comprising a flexible tapering babe-like body, the upper end of which is eniarged and shaped to fit over the face of the user and to form a vizor, nit-ans in the tube to hold it to an open -'position when in use. said means comprising annular rings @an:.ai;;.- spaced apart and of progressively decreasing diameter and secured to the tube, said rings and the tubing portions between the rings being adapted for telescopically interengaging, and the upper ringbeing of a size to accommodate the folding of the vizor portion down into and upon the upper one of the rings, and means for holding the parts to their folded condition.

'2. A breathing appliance comprising a flexible tapering tube-like body, the upper end of which is enlarged and shaped to fit over the face of the user and to form a vizor, means in the tube to hold it to an opefi position when in use, said means comprising annular rings suitably spaced apart and of progressively decreasing diameter and secured to the tube, said rings and the tubing portions between the rings being adapted for telescopically interengaging, the upper ring being of a size to accommodate the folding of the vizor portion-down into and u on the upper one of the rings, means for hol ing the parts to their folded condition, the said means comprising a flexible band loop secured at its ends to the o posite edges of the vizor portion of the b y, said band being adapted for being twisted across the said folded package, as set forth.

3. A breathing appliance comprising a vizor having means or causing it to fit airtight over the face of the user, a flexible tapering air tube, rings of progressively decreasing diameter secured at intervals Within the tube, the said rings and their inter-. vening tube portions being adapted for tele scopically folding within each other, stitching through the tube that passes over and under the rings, and insulating ta es wound around the tubing and the said stitching.

4. A breathing appliance comprising a body formed of a flexible material and including a vizor having means for fitting it air-tight over-the face of the user, and a tapering air-tube pendent from the vizor, a series of rings fitted at intervals on the inside of the tube, means for securing the rings to the tube, the said rings being of progressively decreasing diameters, the upper ring and thaeye portions of the vizor being rela-" tively suc i that the said eye portions of the vizor can be folded side by side within the upper ring, the tube and the other rings being adapted for telescopically engagin each other and the upper ring and means secured to the vizor and comprising an elastic band for snapping over the tube, the rings and the vizor when the several parts are folded together.

5. A "breathing appliance comprising a flexible tapering tube-like body, the upper end of which is enlarged and shaped to fit oveigthe face of the user and to form a vizor, means in the tube to hold it to the open position when in use, the said means comprising annularly corrugated rin suitably adapted for telescopically interengaging spacgd apart and of fprogressiveffi decreaswith each other. ing iameter, means or securing the rings T to the tube, said means including a pliable VILLIAM' LOB GEWAY' 5 tape Wound around the canvas at a point Witnesses:
