A CORPORATION OF NEW YORK.
' BESPIBATOR.
1 Application filed February This invention relates to improvements in respirators.
The object of this invention is to produce a respirator particularly adapted for use of tenants, employees in buildings, and others to enable egress through smoke-filled passages in case of fire.
- Another object of my invention is to produce a respirator which will be always ready for use, which may be applied over the mouth and nose instantaneously and without any preliminary blowing-up or inflation; and which, when so applied, will effectively conform to the contour of the face to completely exclude smoke-charged air and other deleterious gases. 7
Another object of my invention is to enable the instantaneous fastening and release of the device on the head of the user.
Another object of my invention is to provide a readily removable and renewable car tridge having a direct mounting on the respirator body and which will effectively filter and purify smoke-charged air admitted through said cartridge into the body of the respirator so as to cause such air to reach the mouth and nostrils of the wearer in purified conditions.
\Vith these and other objects in view, the invention comprises thecombination of members and arrangement of parts so combined as to co-act and cooperate with each other in the performance of the functions and the accomplishment of the results herein contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which Fig: 1 is a vertical section substantially on .the line 1-1 of Fig. 2 of a respirator embodying my invention applied over the nose and mouth of the user;
Fig. 2 is a transverse section on the line 2-2 of Fig. 1;
Fig. 3 is a rear elevation of the respirator shown in section in Figs. 1 and 2; and
Fig. 4 is a side elevation of the respirator shown in Figs. 1 to 3 inclusive.
Referring now to these drawings which illustrate a preferred embodiment of this invention, 1 indicates a respirator provided with a metallic body or shell 1 having an airinlet opening or nozzle 2 in the outer surface and being provided at the inner perimetral edge with a face-pressing portion 3 having in its upper portion a nose-notch or depression 3. The marginal edge of the face-pressing 4, 1925. Serial No. 6,707.
The respirator 1 is preferably provided with an exhalation valve of any suitable form, and, as shown, an exhaling pipe or nipple 6 is provided at the bottom portion of the respirator-body, to which pipe is fastened an automatically-closing pipe valve 6 of con ventional type.
The respirator 1 is preferably attached to the head by means of a strap 7 having an automatically-fastening buckle buckle 8 is provided with a frame 8 having a toothed bar 8 slidable thereon and actuated to slide into gripping position by a strap- 8. Said screw-threaded nozzle or inlet-orifice 9 havlng removably attached thereto a cartridge 10 containing a filtering and purifying medium such as charcoal, for the purpose of filtering any air passing through said cartridge. Said cartridge is as illustrated, directly connected with the respirator shell or body and is provided With a screw-threaded nipple or flange 10 for engagement with the screwthreaded inlet or orifice or nozzle.
Having described my invention, I claim A respirator embodying a rigid shell adapted to fit over the mouth and nose of the wearer and provided With suitable inlet and outlet openings and having a rigid rim gen erally conforming in outline with the face of 7 the wearer and an annular elastic air-excluding rubber cushion mounted on said rigid rim of said shell and composed of an attaching strip having a detachable connection with the outer surface of said rigid rim and a reentrant and outwardly-opening groove portion provided at one side of its groove With a free edge and connected at the other side edge to said attaching strip and extending inwardly of said rim, said cushion having a seat for said rigid rim adjacent to the connection between said attaching strip and groove portion.
In Witness whereof, I have signed my name to the foregoing specification.
JOHN RICE GIBBS.
