Still other objects of my invention include pro and the ?oat member I9 in such manner as to viding such means that are positive in opera retain the float, member l9 away fromv the inlet ' tion, convenient in use, economical of manufac 15 tothe tube l3; when there is not enough water in practical, and inexpensive article ofthe char acter described. - > 7 ture, relatively simple, and of general/superiority and serviceability. , _ the housing £5 to buoyantly move the valve [9 to a tube-closing position. The invention also comprisesrnovel details of It will be noted that (the channels 21 provide construction and novel combinations, and are rangements of parts, which will more fully ap 20 projections 28 which support the valve l9 when the housing I5 is free of water. When the valve pear in the course of the. following description. is resting on the projections 28, air is permitted However, the drawing merely shows and the fol to move in and out of the housing I5, past the lowing description merely describes one embodi valve l9, through the channels 21. ment of the present invention, which is given by The operation of the invention should be ap» way of illustration or exampleronly. 25 parent from the foregoing description. The mask In the drawing, like reference characters des may be applied to the face as shown in Fig. 1 for ignate similar parts in the several views. protection when a person is in a body of water. Fig. 1 is an elevation view of an embodiment of ' If the person’s head is at or above the surface my invention. Fig. 2 is an enlarged view in section showing 30 of the Water, the housing I5 is thereby above the level of the water, due to the length of the the valve structure also shown in Fig. 1. tube l3. In this position, the person may breathe Fig. 3’ is a fragmentary view showing a mod _ freely, since air passes in and out of the housing i?ed form of valve actuating member.

Referring more particularly to the drawing, I course, there is a direct connection therefrom show a respiratory mask varticle comprising a 35 Of through the tube l3 to the inside of the mask 5. mask element 5 preferably, but not necessarily, If the person goes under water sufficiently for formed, of a transparent, plastic material, sub the housing l5 to be submerged, the buoyancy of stantially semicircular in con?guration, and hav the valve I9 causes it to close the tube l3 as sug ing upper and lower curved edge portions 6 and gested by the broken lines in Fig. 2. With the 1, and a pair of side edge portions 8, which edge 40 tube I3 closed to the ingress of water, the person portions may be provided with a resilient, water may breathe the air in the mask 5 and in the sealing edge strip 9, whereby the mask may be tube l3. The period of being submerged is rela ?tted across and around the face, head and chin, tively ‘short, and when the person again returns and along the sides of the 'face or head of the to the surface, the housing I5 is raised above the user, to provide a water tight mask for a person. 45 surface, thus permitting the water in the hous A pair of resilient or adjustable bands 10 may be ing l5 to drain out and permit the escape of foul provided, and secured, as by fasteners II, to the mask and being adapted to extend around the air and the ingress of fresh air. ' In Fig. 3 I show a modi?ed form of valve back‘of the head and neck of the user, as should which comprises a buoyant, semi-spherical valve be clear. A spacing member I 8 connects and 50 member 22 pivoted at 23 adjacent the end of holds apart the upper and lower bands Iii. ' Mask tube I3, and the operation of this modification 5 extends outwardly from the face as shown, form will be substantially similar to that of valve mem ing a respiration chamber I 2 to which is con ber l9, such that water tending to enter tube l3’ nected tube l3 having a tubular passage in com-1 munication with chamber l2 at one end. will raise ?oat member 22 and cause it to close 5.5 against the end of tube I 3.‘ Raising the valve 27,408,166‘ member 22. from the surface of the water permits it to open, for the ingress of fresh air. While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to modi?cations without departing from the spirit 4 a spring normally to hold said valve against said lugs and free of the aperture, said valve being operable against the tension of said spring by buoyancy to engage the seat in the end of said tube, and said spring unseating said valve when uninfluenced by water and holding said valve open during inspiration of the wearer. ‘3. In a device of the ‘character referred to, the wish to restrict myself to the particular form of combination of: a shield having means for secur construction illustrated and described, but desire ing same to the face and forming an air chamber, to avail myself of all modi?cations that may fall 10. a ‘tube connected to the upper part of said shield within the scope of the appended claims. and having a downwardly directed portion pro Having thus described my invention, what I vided with threads, the end of said tube forming claim and desire to secure by Letters Patent is: ‘a seatha valve chamber threadedly connected with 1.
