RESPIRATOR.
Specification of Letters Patent.
Patented March 2, 1909.
Application filed April 6, 1908. Serial No. 425,530.
To all whom it may concern:
Be it known that I, WILLARD BUCKLEN, J12, a citizen of the United States, residing at Marble Rock, in the county of Floyd and State of Iowa, have invented certain new and useful Improvements in Respirators, of which the following is a specification.
This invention comprehends certain new and useful improvements in respirators and the object of the invention is to provide a simple, durable and efficient construction of device of this character which will enable a person surrounded by noxious gases, dust, or under water, to breath freely without inhaling any of the deleterious matter, and the invention consists in certain constructions, arran ements and combinations of the parts that l shall hereinafter fully describe.
For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:
Figure 1 is a pers ective view of my improved respirator; i 2 is a longitudinal sectional view through the casing thereof; Fig. 3 is a transverse sectional view through the casin and Fig. 4 is a detail view of one of the va ves.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
My improved respirator comprises a casing 1 of any desired construction and design, formed with an inlet nip le 2 and outlet nipple 3, to which, respective y, hose (not shown) are attached.
The casing 1 is provided with a middle partition 4, dividing it into an inlet compartment A and an outlet compartment B. A valve 5 is arranged to seat against that end of the casing 1 which is formed with a nipple 2, such end constituting a valve seat for the valve, and the valve 5 is pressed normally to its seat by means of a coil sprin 6, as clearly illustrated in the drawing. T e casing 1 is divided into two compartments A and B by means of a middle partition 4 and a valve 7 is adapted to seat itself against one side of the partition 4, as a valve seat being pressed thereagainst by a coil spring 8, as shown. The partition 4 is formed with a preferably centrally located opening 9 designed to establish communication between the compartments A and B, such communication being controlled by the valve 7. A
flared mouth piece 10 is formed on or secured to the casin 1, and the latter is arranged to be secured to the face of the operator by means of rings 11, or similar fastening devices secured to the ends of the casing 1 and arranged for the attachment thereto of adjustable straps 12, such straps being secured to rings 13 which are in turn secured to straps 14 constituting the head piece of the device.
From the foregoing description in connection with the accom anying drawing, it will be seen that when tlie device is stra ped to the head of the operator, if it be a iii'eman, or diver, or the like, every ins iration through the mouth piece 10 will craw in fresh air through the nipple 2, this inspiration being permitted by the valve 5, the spring 6 yielding for this purpose. Every exhalation of the erson to which the device is applied will e permitted to escape through the opening 9 of the valve 7, and through the compartment B of the casing 1.
It will thus be seen that I have provided a .very simple, durable and efficient construction of respirator which will be useful for firemen, or divers, or other persons exposed to noxious vapors or fumes, or under water, the arts of the device being ca able of being easi y manufactured and readi y assembled.
Having thus described the invention, what is claimed as new is: A device of the character described, comprising a casing formed at its ends with inlet and outlet nip les and provided with a middle partition ividing it into two com artments, said partition being formed wit an opening extending therethrough, the casing being further provided with a mouth piece and with an opening leading from the entrance compartment outwardly within the mouth piece, a valve yieldingl held against the inlet end of the casing and lbcated within the inlet compartment whereby to control the admission of air through the inlet compartment and thence within the margin of the mouth piece, a corresponding valve located Within the other compartment and a handle held a ainst rotation to close the opening formed therein.
In testimony whereof I affix my signature in presence of two witnesses.
