PROTECTOR HOOD Filed Feb. 2, `1946 Patented Dec. 9, 1947 UNITED STTESPATENT OFFICE PROTECTOR HOOD Anna Ford Hall, Ansonia, Conn.

Application February 2, 1946, Serial No. 645,062

(Cl. 12S- 146) 3 Claims. l

This invention relates to nasal and lung protectors, and aims to provide an efficient and practical protective means for use by workers in such trades or industries where fine particles of dust or liquid globules are present in the ambient at.- mosphere, whereby the worker can breathe freely without inhaling the dust or liquid particles. It is well known that serious trouble can result from such inhalation, and it is believed that the utilization of the protector herein presented will effectively prevent such particles from being breathed in by the worker.

The above broad as well as additional and more detailed objects will become apparent in the following description, wherein characters of reference refer to like-numbered parts in the accompanying drawings. It is to be noted that the drawings are intended for the purpose of illustration only, and that it is neither desired nor intended to limit the invention necessarily to the specific details of construction shown excepting insofar as they may be deemed essential to the invention.

Referring briefly to the dawings,

Fig. l is a front elevational View of the pro tective hood.

Fig. 2 is a rear elevational view of the same.

Fig. 3 is a cross-sectional View taken on the line 3-3 of Fig. 1.

Fig. 4 is a cross-sectional view taken on the line 4--11 of Fig. 1.

Fig. 5 is a cross-sectional view taken on the line 5 5 of Fig. 1.

Fig. 6 is a fragmentary side elevational view of the protector.

Referring in detail to the drawings, the numeral Ill indicates the shoulder portion and the numeral II the head portion of a cape-like hood adapted to cover the head, neck and shoulders of the wearer. The head portion II comprises a substantially cylindrical member having the front and rear walls I2 and I3, respectively, joined by the enclosing peripheral side wall Ill having an opening I5 at the bottom for the neck of the wearer. The shoulder portion Ill, which is shaped as seen in Figs. 1 and 2 to register over the shoulders and part of the necl of the wearer, comprises at the rear the cover or back I3 which is a unitary continuation of the head portion I3. At the front of the shoulder portion Ill, the cover member I1 depends from the lower portion of the head portion I0. Shoulder strips i8 join the complementary upper edges of the shoulder cover members I6 and I1.

An opening I9 is formed in the member I2 to provide a vent for the mouth, and around this opening a fiange 23 is formed about which a cap 2| is slidably mounted, the outer end of the .cap having the opening 22 therethrough surrounded by the flange 23. A perforated closure strip 24, backed by a lter pad of any desired construction or material 25, which registers against a ller flange 26 mounted within the ange 20, serves to permit air to enter through the opening I9, and the lter serves to trap any dust or liquid particles which may abound in the air. The cap 2| is readily removable from the flange 26, being retained thereon frictionally, for replacement .of the filter and cleaning the perforated closure 24.

Spaced eye openings 21 are likewise formed in the face member I2, and a circular flange 28 surrounds the same, about which registers frictionally the cap having its end 36 open and provided with the flange 3|. An inner filler flange 32 is mounted within the flange 28, and a plain glass disk 33 is thus removably clamped between the flanges 3| and 32, so that the glass may be removed for cleaning. The eye openings are thus sealed.

A nose opening 3d is also formed in the face member I2, surrounded by the flange 35, in which a filler flange 36 is mounted. A cap 3'1 frictionally and removably surrounds the flange 35, and its end is open at 38 and surrounded by the flange 39. Behind the ange 39 a perforated disc 40, backed by a filter pad lil, registers, and both the disc and the pad are thus removably clamped between the flanges 39 and 36, so that both may be removed readily for cleaning or replacement. The construction of the ear members 42 is substantially similar to that shown for the nose member, and the ear members have therefore not been illustrated in detail.

The bottom of the shoulder member Il] is, of course, although not shown, open, so that the entire hood may be slipped on the wearer over the shoulders, with the head registering in the portion I0. Of course no dimensions are shown or indicated, but it is to be understood that the various parts of the device are to be so proportioned and dimensioned as to permit its functioning as and for the purposes set forth.

When the hood is used in the manner stated, the wearer may breathe freely through the nose member or, also, the mouth member, and he may heal` through the ear members and see through the eye members. Meanwhile the hood fits the entire shoulder, neck and head of the wearer, covering those parts completely so that no dust or liquid particles may be breathed in while he contaminated. In this Way the worker is protected from the consequences, which are frequently serious, of inhaling such particles into his nasal or sinus passages and the lungs.

The entire device may be readily and inexpensively made of any suitable material, such as, 'for instance, a cellulose acetate plastic material, or any other plastic material which may be adaptable to the purpose. The material would be light in'weight yet sulciently sturdy. To facilitate putting the hood on or taking it off, a slide fastener closure IEB is provided at the vertical median line of the back member I3-I6, extending from a point near the top of the head member to and through the lower edge of the back shoulder member I6. The wearer himself may, therefore, readily apply or remove the hood on himself. When the hood is thus worn, and the slide fastener closed, the lower peripheral edge of the shoulder member I closes snugly about the shoulders of the wearer and thereby prevents leakage of dust-laden air into the hood.

The feature of making the mouth, nose, eye and ear closures removable for cleaning or replacement of the filters,` is important in that such cleaning or replacement may be made quickly and readily With a minimum loss of time to the Worker.

Obviously, modifications in form and structure may be made without departing from the spirit and scope of the invention.

I claim:

1, A hood of the class described comprising a unitary head member and shoulder member, said head member comprising a substantially cylindrical hollow member having front and rear faces having openings through the face thereof for eyes, nose, and mouth, and openings through the front cylindrical wall thereof for ears, said nose, mouth, and ear openings having perforated closures removably mounted therein and having removable lters mounted therein behind said closures, said hood having slide fastener means for tightening the lower edge of the same about the shoulders of the wearer.

2. The hood set forth in claim 1, said slide fastener means being positioned along the vertical median line of the hood at the back thereof and extending from a point near the top of said head member down to and through the lower peripheral edge of said shoulder member.

3. The hood set forth in claim 1, said eye members having glass disks removably mounted therein.
