Description
DEDICATORY CLAUSE
The invention described herein may be manufactured, used, and
licensed by or for the Government for governmental purposes without
the payment to me of any royalty thereon.
My invention relates to an improvement in gas masks for combat and
industrial use, such as the mask disclosed in U.S. Pat No.
2,910,979. My improvement provides a means for drinking and
resuscitation while the mask is being worn and without
necessitating removal of the mask.
There has been a long felt need in the protective mask art to
develop a satisfactory means for drinking and resuscitation in
contaminated atmospheres requiring the use of a gas mask, and my
invention was conceived and reduced to practice to solve this
problem and satisfy this long felt need.
A principal object of my invention is to provide a means
incorporated in a conventional gas mask whereby drinking and
resuscitation can be accomplished while wearing the mask.
Another object of my invention is to provide a drinking and
resuscitation means for a conventional gas mask which is simple and
economical to manufacture, has few parts, is not subject to
tinkering and damage, and which can be installed in the mask in the
field.
Other objects will be obvious from or will appear in the
specification hereinafter set forth.

My invention and FIGS. 1 to 15 will now be described in detail as
follows.
Mouthpiece 2 is fixedly connected to one end of rubber tubing means
3 by any conventional means such as adhesive, hose clamp means,
etc. The other end of rubber tubing means 3 is connected in the
same manner to the flange of male member 7 of a plastic or metal
lead-in grommet 4; grommet 4 being mounted within facepiece 5 of
mask 1 by screwing a female cap member 6 of the grommet onto the
threaded male member 7 of the grommet inserted through a hole in
the nosecup 60. Metal band 8 having metal strip 59 welded thereto
is fixedly mounted to tubing 3 in any conventional manner, such as
taping etc., to provide rigidity to the tubing and to permit the
mouthpiece to be adjusted to the comfort and facial configuration
of the individual mask wearer. Mouthpiece 2 and tubing 3 are
located adjacent to and behind the mask voice transmitter 9. A
second rubber tubing means 10 has one end connected to the male
grommet member and the other end to the mask male drinking and
resuscitation connection member 11. Rubber dust cap 12 is fixedly
connected to male connector 11 by any conventional means such as
taping etc., of rubber strap 13 to connector 11; the dust cap being
provided to cover connector 11 when the mask is not being used for
drinking or resuscitation. When the mask is not being used for
drinking or resuscitation, connection member 11 and tubing 10 are
prevented from dangling free by connecting rubber strap 14 to metal
or plastic fastening means 15 by means of hole 16; the fastening
means being a double headed pin inserted through a hole in cover
17. An alternate mode of mounting tubing 3 and 10 to mask 1, as
shown in FIG. 7, involves connecting tubing 3 to tubing 10 by rigid
ferrule 20 and threading the assembled tubing and ferrule through
flanges 18 and 19 molded integrally to nosecup 60 and facepiece 5
respectively. Alternative to using rubber tubing 10 for the
drinking and resuscitation embodiment, a rigid tee conduit means
21, having a rotatable arm 22 which rotates through 180.degree. in
a plane parallel to the plane of the mask vertical axis and
conduits 26 integral with arm 22, is mounted in the mask voice
transmitter frame 23 below the voice transmitter 9. Tee 21 is
mounted in voice transmitter frame 23 and connected to tee 24 by
conventional rigid tubing means; conduits 26 passing through rubber
grommet means 25 to be connected to tee 24, grommet 25 permitting
flexibility to move mouthpiece 2 to the mouth of the mask wearer.
Tee 24 is identical to tee 21 except that it does not have a
movable arm 22, but tee 24 has a nonmovable arm 27 mounted above
and integral with conduits 26; arm 27 being in a plane parallel to
the plane of arm 22. This embodiment, as shown in FIGS. 3, 4, 5,
and 6, is utilized to swing arm 22 above conduits 26, connect
canteen means 28 or resuscitation means 52 to male connection
member 11, fixedly mounted by any conventional means such as rubber
tubing and clamp within arm 22, and permit fluid flow to the mask
wearer. To enable drinking without removing the mask from the
wearer's face, canteen 28 is provided with a cap 29 having a quick
disconnect coupling 30 mounted to the cap by threaded member 31 and
nut means 32; threaded member 31 being hollow, cylindrical in
configuration, and having a square shaft 33 located within member
31 to form channels 34 to permit fluid flow between member 31 and
shaft 33, as shown in FIGS. 8, 9, and 13. Shaft 33 is provided with
a head means 35 to retain spring 36 in position and maintain the
shaft under spring tension. The opposite end of shaft 33 is
provided with a head means 37 to retain washer 38 in position and
close off fluid flow through channels 34 when the mask wearer does
not wish to drink and has not connected male connector 11 to
coupling 30. To drink, dust cap 39 is removed from coupling 30,
male connector 11 is inserted within coupling 30, as shown in FIG.
9, so that projection 40 of shaft 33 engages the recess within
valve 41; valve 41 being held under spring tension by spring 42,
the spring being held in position by projection 43 of spider plate
44 and projection 45 of valve 41. Pressure is applied to male
member 11 until lip 46 passes over annular ridge 47 within coupling
30 and ridge 47 rests within annular recess 48 of member 11. When
male member 11 reaches the position wherein ridge 47 is within
recess 48, valve 41 has been pushed back from seat 49 by depression
of spring 42 and washer 38 has been pushed back from closing off
channels 34 by depression of spring 36; fluid flow through channels
34 occurring prior to removal of valve 41 from seat 49. Fluid will
then flow from canteen 28, into cap 29, into male member 11,
through spider plate 44, through tubing 10 or rotatable member 22
on to mouthpiece 2, and to the mouth of the mask wearer. Hole means
50 can be provided in male member 11 between lip 46 and valve seat
49 for alignment with hole means 51 in coupling 30 to provide fluid
flushing action to remove any contamination which might accumulate
within member 11 or coupling 30 during connection of member 11
within coupling 30. The location of holes 50 and 51 is such that
they align, as shown in FIG. 11, after the start of fluid flow
through channels 34 but prior to removal of valve 41 from seat 49
to permit fluid to flush through to the outside environment, and
the holes are out of alignment, as shown in FIG. 10, after removal
of valve 41 from seat 49 to permit fluid flow to the mouth of the
mask wearer as described above. The resuscitator 52 embodiment of
my invention, as shown in FIGS. 2 and 14, is employed when someone
attempts to revive a person in a contaminated atmosphere, such as
gas or smoke, requiring the wearing of a protective mask by the
person attempting to revive, Mouthpiece 53 is held on the mouth of
the person requiring resuscitation and mask male member 11 is
inserted within resuscitator coupling 54 until annular ridge 55 of
the coupling snaps into annular recess 48 of member 11, in the same
fashion as described above regarding the drinking embodiment. When
ridge 55 is within recess 48, pin 56 has removed valve 41 from seat
49 through depression of spring 42 to permit the breath of the
person attempting to revive to pass through the spider cross
section 61, as shown in FIG. 15, of coupling 54, to force open
disc-type valve 57, which prevents feedback to the person
attempting to revive during inhalation, and to permit the air to
pass on through rubber hose means 58 and mouthpiece 53 to the
person being revived.
I wish it to be understood that I do not desire to be limited to
the exact details of construction shown and described, for obvious
modifications will occur to a person skilled in the art.
