WELDER’S MASK

This invention relates to improvements in
members 21 and 2B.
welder’s masks and more particularly to a novel
mask having an automatically operable eye pro
tecting shield.
.
I am familiar with the fact that eye shields
have been provided in conjunction with welder’s
masks when the latter are pushed upwardly above
the face of the wearer, but in the devices in
present use, the eye shield must be moved man
ually to the position desired. When the welder’s
mask is down it is preferable that the eye shield
be raised out of the line of vision. The neces
sity for moving the eye shield and the mask
proper in separate manual operations slows the
work of the operator, and it; is one of the ob
jects of this invention to provide a welder’s mask
including a conventional light ?lter and a sep
arate eye shield which will be withdrawn up
wardly automatically when the mask proper is
pulled down before the welder’s face.
Other and further objects of the invention will
appear as the description proceeds, reference be
ing had to the accompanying drawings, in
which:
Fig. 1 is a view in vertical section of a welder’s
mask embodying my invention.
Fig, 2 is a similar view of the device with the
mask proper turned upwardly in the out of use
The arms 35 and 36 have
outwardly directed frictionaldetents 3‘! and '38
contacting the inner side walls of the mask II.
In use, the operator’s action in pulling the
mask i l down to bring the ?lter glass I2 into

his line of vision will cause the inner surface of
the mask H to frictionally engage the detents
31 and 38 causing them to move downwardly
thus raising band 29 with the eye shield 30 up
wardly out of the line of vision. When the mask
H is raised to its retracted position above the
line of vision of the wearer, an opposite action
will lower the eye shield 36 into the use posi
tion within the line of vision.
It will be understood that the device is capable
of many modi?cations in structure and design,
without departing from the spirit of the inven
tion, within the scope of the appended claims.
Having thus described my invention, what I
claim and desire to secure by Letters Patent
of the United States is:
1. In a protective mask, a supporting head
band, a pivoted face shield thereon, an auxiliary
frontal band, pivot elements mounting said aux
iliary band and spaced forwardly symmetrically
of the mid-points of said head band, and tan
gential lever members integral with said auxiliary
vband and extending rearwardly and outwardly
position.
Fig. 3 is a plan view partly in section and 30 from the pivot elements and bearing frictionally
against the inside of said face shield.
partly in elevation showing the friction detents
for raising the transparent eye shield.
Fig. 4 is a front view partly in elevation and
partly in section.
Referring more particularly to the drawings, .
the numeral Ill refers to the device generally,
having the conventional mask l [provided with
the light ?lter glass l2, the longitudinal head
band l3 and the transverse head band l4. But
tress straps [5 and I6 are secured to the trans
verse head band I4 by means of the rivets I1, l8,
l9 and 20.
The transverse band 14 is secured at its ends
to the longitudinal head band 13, as by means
of the rivets 2| and 22.
The head bands I3 and I4 and the buttress
straps l5 and I6 retain the pivot members 23
and 24 which comprise the pivot points for rais
ing and lowering of the mask ll, to bring it
away from or into the line of vision of the user
as desired.
2. In a protective mask, a supporting hori
zontally disposed head band, a pivoted face shield
thereon, an auxiliary substantially semi-circular
frontal band, pivot elements mounting said aux
iliary band for arcuate movement and spaced
forwardly symmetrically of the mid-points of
said head band, and tangential lever members
integral with said auxiliary band and extending
rearwardly and outwardly from the pivot ele
ments and bearing frictionally against the inside
of said face shield.
.
3. In a protective mask, a horizontal head
band, a face shield pivoted thereon, an auxiliary
frontal band exteriorly of said head band, an
eye shield secured to said frontal band, pivot
elements mounting said auxiliary band and
spaced forwardly symmetrically of the mid
points of said head band, tangential lever mem
bers integral with said auxiliary band extending
rearwardly and outwardly from the pivot ele
ments, and exteriorly rounded projections ad
Forwardly of the longitudinal centers of the
band [3 and ?xed thereto, are the pivot members
jacent the ends of said levers in frictional en
2'! and 28, on which is pivoted an arcuate band
gagement with the inside of said face shield
29 carrying a conventional transparent eye shield 55 whereby when the latter is lowered the trans
parent eye shield will be raised above the line
30, af?xed thereto by means of male and female
snaps at 3|, 32, 33 and 34. The band 29 has
of vision and vice versa.
