A CORPORATION OF PENNSYLVANIA.

vanvn nnvrcn ron. nnsrmn'rons on r111: LIKE.

- Application filed February My invention relates to respirators or like dcviceswhich comprise a close-fitting airchamber having suitable provision for inhaling and a separate exhaling outlet, and it consists in an improved valve arrangement for the'latter as hilly described in connection with the accompanying drawing and clearly defined in the subjoined claim.

Fig. l is a diagrammatic side elevation of a respirator having my improved outlet valve applied thereto; Fig. 2 is an enlarged fragmentary cross-section of the chamber wall with the valve applied thereto, taken on the line 22 of Fig. 1; Figs. 3 and 4 are respectively an edge view and an inner plan view of the valve cap; and Fig. 5 is a sepatively retained by the cap.

The respirator indicated comprises a cup shaped air chamber a, formed of soft rubber and adapted to fit closelyto the face of the wearer, its open contracted forward portion being provided with a suitable casing 72 adapted to contain suitable filling material through which the inhaled air passes; a separate outlet opening 0 being provided in the chamber wall for discharge of the exhaled air.

In my improved construction the wall outlet opening 0 isrprovided with an exterior circular boss 5'; which boss forms a'seat for the rim portion 6 of a disc valve having an integral flap 7 adapted to normally close the opening, and is also provided with a p ripheral circular groove 8 adapted to be engaged by the valve cap separately shown in Figs. 3 and 4. z

This valve cap 10 is formed of sheet material pressed to cup-shape-as shown; the rim flange thereof having portions 11 which are adapted to fit over the wall boss 5, with in rate Vievwof the flap valve which is opera 18, 1927. Serial No. 169,215.

tervening notched portions 12. These notched portions 12 of the cap flange are set outward from the boss-engaging portions 11 so as to provide free discharge openings 13.,- through the cup flange when the valve flap 7 is opened by exhaling pressure; the increased diameter of the notched flange portions 12, extending below the valve-seating, face of the boss 5 but being spaced away from the periphery of the latter; and the boss-fitting flange portions 11 being formed with interior ofi'sets 1a which press the rim portion 6 of the valve to its seat upon the boss when the cap is in place upon the latter; and also having interior radial projections .15 which serve as detents adapted to engage in the peripheral groove 8 of the boss when the cap is so placed. My improved valve cap thus provides a very simple and neat valve-securing device which is adapted to permit free discharge of the exhaled air while forming a .very satisfactory covering of the wall opening, and which is very securely retained in place though readily removable when desired. The specific form set forth may be readily modified within the invention as defined in the claim.

' What I claim is: I

In combination with a chamber-enclosing 7o respirator-wall or the like having a discharge aperture with a surrounding valve-- retaining boss; a valve devige comprising a flap-valve seatingupon'said boss, and a valve-retaining cap having an annular flange with spaced apart boss-engaging portions having valve-contacting offsets and intervening portions of enlarged diameter having air-escape notches. o In testimoney whereof I afiix my signac ture.

HARRY F. SHINDEL.
