' haling of noxious substances such as dust,

smoke, tobacco leaf powder, etc.

A further object of the invention is to provide a respirator adapted to conform to the contou: ofthe lower portion of the nose and be heldin operative position thru engagement with the wings or ala-nasies of the n ose. A further object of the invention resldes in the provision of a respirator adapted to be securely audcoxufortablv heldin placeby engagement with intimate contact, the lower base portion of the nose, and without hindering easy breathing thru the nose.

A further object resides in the provision of a respirator which will be extremely light in weight so as to not cause any discomfort to the wearer, and'one wherein the filter proper is readily and easily renewable.

Other objects and advantages of the 1nvention will be apparent during the course w of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification and in which drawings:

Fi re 16 is a vertical section on line 16-16 of Flgure 14.

Referring to the drawings in detail, and wherein similar reference characters designate corresponding parts thruout the several views, the letter V`A designates one form of protector or respirator, B a second form, C a third form, and D a fourth form. In each form of the invention the shell or body portion of the protectors are intended to cover the lower` portion of the nose and so lconform thereto as to be held in position wholly thru engagement about the wings or ala-nasies of the nose. In each form of invention, the protectors are preferably made lfrom a relatively light and yieldable material such as celluloid or-the like.

Referring first to the protector A, the protector is made in two halves 5 and 6 sohingedly connected along their lower sides as'to be normally urged together into a formation conforming to the contour of the lower portion of the nose. Each. of the sections 5 and 6 is formed with a bottom wall 7 having a straight inner edge and a curved outer edge. The wall -7, whenV the sections 5 and 6 are in a closed position .form a substantially heartshaped bottom -for the protector providing a. concaved rear edge lEach substantially flat bottom wall 7 is provided withan opening 9 conforming in outline to the nostril or nazal cavities of the nose.

j Suitably formed along the inner straight edges of the bottom walls 7 are hinge barrels 10 which are arranged in pairs adjacent the front and rear ends of the plates and receive a suitable hinge pin 11 for hingedly connecting the sections 5 and 6. Encircling Vthe pin 11 between the hinge barrels 10 is a spiral spring 12 the ends of which are extended and act one upon each of the bottom walls 7 for normally urging the sections 5 and 6 into a closed position. Projecting upwardly from the outer arcuate edge of each bottoni wall 7 is a cupped side plate 14 the rear portions of which are outwardly bulged providing socket portions 15 for receiving the ala-nasies 16 of the nose N. The socket portions 15 extend slightly above the forward Y *The forward-edges of the side plates 14 have a lap joint fit as at 17 in Figure 2 when the sections 5 and 6 are in closed relation. The rounded edges of the sockets 15 conform to and engage in the arcuate crease'or cavity formed at the rear of each ala-nasi.

Each section 5 and 6 is provided in parallel spaced relatiq'i above its bottom wall or plate 7 with an upper wall or rest plate 18 of like conformation as that of the plate 7 and connected along their straightrinner edges by webs 19. These walls 18 and Webs 19 co-act with the plates 7 and 14 to provide a Hat or shallow chamber 20 in the lower f portion of each section 5 and 6 with the chambers opening at the rear concaved sides of the protector. The plates 18 are each provided with an opening 21 for aligning directly above the openings 19 in the bottom plate 7. The webs 19 forming the inner walls of the chambers 20 act as stops for limiting closing movement of the sections 5 andA 6 by the spring 12, and the hinged connections of the sections is such that when the webs 19 engage, the bottom walls 7 will'be inclined upwardlyfrom the hinge point so that the forward ends of the side plates 14 will overlap to form the lap joint 17. This overlapping of the forward ends of the side plates 14 serves t exclude air from entering the protector wh in position upon the nose and also allows for slight variations in the width of the nose towhich the protector is applied.

Adapted to be removably inserted into eachrof the shallow chambers 20 from the reary open sides thereof is a strainer 22 including a holder embodying upper and lower platesor flaps 23 and 24 respectively hingedly connected at their tips or forward ends by a hinge joint 25. These plates 23 and 24 are of a shape corresponding to the shape of the chambers 20 and each is provided with a substantially oval-shaped opening 26 which when the strainers are inserted in the cham- ,20. The rear edges of the plates 23 and 24 are of arcuateshape and one plate of each strainer' is provided at its rear arcuate edge with an arcuate-shaped rest late 27 which when the protector is applie for use is intended to bear against the upper lip of the user directly beneath the nose. Adapted to be removably disposed between the plates 23 and 24 is a suitable piece of gauze 28 serving as a filter. When the plates 23 and 24 are closed upon one another they serve to retain the gauze in position extending across the openings 26 in the plates.

In Figures 1 and 5 it will be seen that the forward edges of the cupped side plates 14 are inclined'upwardly and rearwardly and co-act with the upper walls 18 of the chambers 20 to provide a .substantially triangularshaped pocket for receiving the tip of the nose.

In the form Aof protector shown in Figures 7, 8 and 9, the cupped side plates 14 of the sections 5 and 6 are hingedly connected along their forward edges by a hinge joint 30. A suitable coil spring 31 is provided for normally urging the Sections 5 and 6 together. vEach section 5 and 6 is provided at its lower portion with a shallow chamber 20 having aligning openings in the upper and lower walls thereof. These chambers '20 are each adapted to removably receive a strainer 22 each including a holder embodying hingedly connected flaps 32 provided with aligning openings 33, and between which flaps is disposed a suitable piece of gauze 28. The rear edge of one of the ilaps is downturned to provide an arcuate rest plate 27 Each of the side plates 14 at their rear ends are outwardly bulged to form socket portions 15 for receiving the wings 16. Extended inwardly from each web portion 19 of the sections 5 and 14 is a triangularshaped fin 34 and which fins overlap with one another when the sections are in closed relation to provide a lap joint sealing the bottom of the protector. Th'e edges of the fins 34 also act to limit the closing movement of the sections thru engagement with the webs 19.

The Kprotector B together with the strainer 22', and likewise the strainer 22, are preferably formed from a light flexible material such as celluloid or the like.

In the form of protector C shown'in Figures 10 to 13 inclusive, the same includes a main body portion conforming in outline to the lower portion of a human nose and provided at the rear portion of its side walls with outwardly bulged portions providing sockets 40. The bottom wall 41 of the main body portion 38 is provided with two ovalshaped openings 42 which align with ovalshaped openings 43 provided in a false lboty tom 44. T he false bottom 44 is spaced slight- Aly above the bottom plate 41 and provides a shallow pocket orchamber 45 opening at the rear arcuate edges of the plates 41 and 44.

Extended about the marginal edge of the 'body portion 38 is a piece of spring wire 46 which acts to normally contract the main body portion about its u per edge and along the rear arcuate edges o the socket portions 40. This contractlng of the body portion tends to hold the protector in position upon the nose of the wearer.

The chamber 45 is intended to removably receive a strainer 48 including a holder embodying'hingedly connected upper and lower flaps 49 and 50 conforming to the shape and outline of the chamber 45. The strainer 48 is substantially heart-shaped and the flaps \49 and 50 may be hingedly connected at their forward ends by a, suitable hinge joint 51. One of the fiaps, and preferablyv the upper flap 49 is provided along its rear edge with an arcuate-shaped rest plate 52 which when the flaps are in closed relation extend over the rear edge of the lower flap 50. The plates 49 and 50 are each provided with a pair of oval-shaped openings 53 for aligning with the openings 42 and 43 when the' strainer is inserted into the chamber 45. The hinged 5 lflaps 49 and 50 are intended to receive and retain therebetween a suitable piece of gauze 55 which extends over the openings 53 and serves as a filter member. The holder portion of the strainer 48 may be formed of any suit- 'alliily light material lsuch as Celluloid or the li e.

Referring now to the form of protector D shown in Figures 14, 15 and 16 the same includes a pair of interlocking inner and outer members 60 and 62 respectively which may be formed from light yieldable material 'such as celluloid. The members 60 and 62 are of like general outline and have a configuration conforming to the lower portion'of the nose. The outer member62 is formed with a bottom wa1l`63 about the sides and forward edge of which is an upstanding portion forming side plates 64 bein outwardly bulged at their rear portions fning socket portions 65. The 'rear concav edge of the bottom wall 63 is downturned as at 66 providing an arcuate grip plate. This arcuate plate 66 also serves as a sti'ener for the rear edge of the bottom wall 63. Provided in the bottom wall 63 isa pair of oval-shaped openings 67.

The inner member for interlitting with the outer member-62 is formed with a bottom wall 63' conforming to the shape of the wall 63.- Extended upwardly from the side C? and forward edges of the' bottom wall 63 is van upstanding portion providing side plates belng outwardly b ulged at their rear portions providing socket portions for.

interftting in the sockets 65 when the members 60 and 62 are in assembled relation. The rearconcaved edge of the bottom wall 63 is downturned providing an arcuate rest plate `68. The bottom wal163 is also provided with a pair of oval-shaped openings 70 for aligning with the openings 67. Projecting u wardly from the forward upper edge of t e inner member 60 is a hook-like nib 80 which zprojects above the upper edge of the outer member 62 for separation of the members.

Extended about the marginal edge of the outer member 62 is a length of spring wire 82 which tends to normally contract the protector. The spring wire 82, and also the spring wire 46 as shown in Figures 1() and 11 may be secured in position by curling a portion of the material at spaced points to extend rial about which the members 60 and 62 are formed, the member 60 may be readily inserted into the member 62 and when in position the outwardly bulged socket portions 65 will vengage in the sockets 65 and hold the `members in lassembled relation.

Thus it will be seen that in each form of protector A, B, C and D that a substantially false bottom is provided between which and the true'bottom a filter is removably placed between aligning overlying openings. It will further be noted that in each form of protector that means is provided for yieldably clamping the protector to the lower portion of the nose, this means in the forms of protector A and B being the coil spring` associated with the hinge joint of the sections and in the forms C and Dtaking the form of a spring wire extended about the edge of the protectors. In each form, a rest plate 1s provided for bearing engagement with the upper lip of the user to prevent any discomfort to the wearer. In each form of protector is also provided the socket portions for yieldable gripping engagement with the wings of ala-nasies of the nose.

From the foregoing description it will be apparent that a novel and improved-type of respirator or nose protector -has been provided which is of such ,construction and formation as to be securely and comfortably held in place by engagement with intimate contact the lower portion of the nose. The device when applied 'as will be observed,

forms Substantially a pocket for receiving the tip portion of the nose, while the cupped or socket vportions will have a firm and comfortable grip upon the win sofV the nose.
