CLASP FOR GOGGLES
Charles Fischer, New York, N. Y.
Application February 25, 1937, Serial No. 127,593
2 Claims.
The invention relates to improvements in clasps
for goggles and has particularly to do with clasps
for goggles used by aviators, drivers of racing
automobiles, motor boats or any other apparatus
5 where a high speed is maintained.
The present invention has to do with an im
proved head band clasp and has for its object to
provide a simple clasp which is adapted to lock the
head band securely to the goggle, and which is
0 not liable to break off or work loose from the
goggle, while the goggle is being worn.
Other objects and advantages will become ap
parent as this speci?cation proceeds. Referring
to the drawing forming a part thereof:
15
Fig. 1 is a front elevation of the goggle embody
ing the improvements of the present invention;
Fig. 2 is an enlarged elevation of one form of
improved head band clasp;
Fig. 3 is a section taken on line 3--3 of Fig. 2,
20 the hook being in its closed position; and Fig. 4
is a sectional view taken on line 4-—4 of Fig. 2.
The goggle includes a pad in composed of soft
rubber, provided with eye openings I I, and adapt
ed to e?iciently and comfortably conform to the
25 face of the wearer.
Surrounding the eye open
ings and secured to the pad are light metal frames
! 2, hinged together at i3 and adapted to carry the
lens members l4. Members 15 at the sides of the
frame carry perforated lugs l6 which are utilized
30 as eyes for the hooks of the head band clasp here~
inafter described.
Heretofore, the head band has carried a thin
light open ring which was passed through the ears
of the frame and then twisted by pliers. The
35 twisting of the ring strains it and crystallizes it.
Thereafter, the stresses to which the ring was sub
jected imposed further strain and led to break
age at the point of twisting.
The possibility of the head band clasp breaking
40 or working loose from the goggle and the result
ing inconvenience and perhaps danger to the
user, is avoided by the clasp shown in Figs. 2, 3
and 4c, in which a strap 23 is provided, slotted at
24 to receive one end of a head band 25.
The
45 strap has a forwardly extending pocket 26, the
strap and pocket being stamped from one piece of
metal. Passing through the sides of the pocket
is a pivot pin 21, and a strong hook 28 is pivoted
on this pin. As illustrated, pivot pin 21 is ar
50 ranged off-center, i. e. below the central horizontal
plane of the pocket and below the line of force
acting on hook 28. This arrangement results in
the hook being securely locked to the frame when
in closed position. In addition, the upper sides
55 of pocket 26 are pinched at 29 to provide a pair
of spring jaws. When the hook is open, as shown
in full lines in Fig. 2, the jaws act to hold the hook
(Cl. 24-—232)
up and in a position which facilitates the passing
of the free end of the hook through the perforated
noses of the frame. When the hook is closed, the
jaws give way to allow the hook to pass and then
spring back behind the hook. Also, as shown,
the extended lip 30 of pocket 26 is adapted to be
engaged by and serve as a stop for the free end of
hook 2B.
The above-described clasp is adapted to over
come the di?iculties experienced with prior types.
There is no twisting of the clasp to attach it to
the frame, and, consequently, no premature
straining of the hook, which would lead to break
age. The clasp is adapted to securely lock the
head band to the goggle and the possibility of the
clasp opening and the head band becoming disen
gage'd from the goggle, is avoided with certainty.
It will be understood, that, in carrying the in
vention into practice, changes may be made in the
improvements described, without departing from
the principle thereof.
I claim:
1. A clasp for goggle head bands comprising a
slotted head band receiving member, a hook re
ceiving member attached to one side of the head
band receiving member, said hook receiving mem
her being U-shaped in cross-section both longi
tudinally and transversely, and a hook pivoted in
said hook receiving member adjacent the junc
ture of the longitudinal and transverse closed
edges thereof and extending toward the open side
of said hook receiving member, the free end of

said hook engaging the longitudinal closed edge
of said hook receiving member at a point remote
from the pivot of said hook when the hook is in 35
the closed position.
‘
2. A clasp for goggle head bands comprising a
slotted head band receiving member, a hook re
ceiving member attached to one side of the head
band receiving member, said hook receiving mem- 40
her being U-shaped in cross-section both longi
tudinally and transversely, and a hook pivoted in
said hook receiving member adjacent the junc
ture of the longitudinal and transverse closed
edges thereof and extending toward the open side 45
of said hook receiving member, inwardly extend
ing spring jaws formed in said hook receiving
member near juncture of the closed transverse
edge and the open edges thereof, said hook in its
open position being located on one side of the 50
spring jaws and in its closed position on the
other side thereof, and the free end of said hook
engaging the longitudinal closed edge of said hook
receiving member at a point remote from the
pivot of said hook when the hook is in the closed 55
position.
