of Pennsylvania.
Application April 9, 1936, Serial No. 73,438
5 Claims. (Cl. 24—81)
My invention relates to a device for adjustably a different construction of the strap engaging
connecting two straps or strap ends, my object aperture.
being to provide a simpli?ed device for the pur
pose, and of improved security and usefulness
5
with quick and easy adjustability.
'
One speci?c use for which my improved device
is particularly applicable is'to unite the ends of
a ?exible strap of the type set forth in my prior
Patent No. 1,876,770, issued September 13, 1932,
ll) to connect a pair of goggle framings or the like,
which necessitates a secure engagement of the
band ends to ?xedly spread said framings, and
a ready adjustability of said ends to vary such
spread for the particular user. And further, as
such ?exible connecting means must necessarily
be made of relatively small size, and adjustment
desirably effected by workers’ ?ngers more or less
clumsy and unskilled in delicate work, such con
nection must provide for simpli?ed manipulation.
With such simpli?ed ready manipulation in
mind I provide for an angular spread of the free
ends of the straps to facilitate separate gripping
thereof, avoidance of their overlying the goggle
framings to obstruct vision through the latter,
. and an improved angular return bend engage
ment with the plate, simply securable to the lat
ter in ?xed adjusted relation thereto by means
preferably united to the plate so as to avoid un
intentional separation and loss.
With the above main objects in View my in
vention comprises the adjustable connecting de
vice more fully described in the following speci
?cation, in connection with the accompanying
drawing, and the novel features thereof are spe
a." ci?cally set forth in the appended claims.
Fig. 1 is a top View of an ordinary pair of gog
gle framings connected by a ?exible strap, the

Referring particularly to Figs. 3, 4 and. 5, which
show on an enlarged scale a connecting device
embodying a preferred construction of my inven- ;
tion, I!) indicates a connecting plate having two
similar apertures l I, l I’, and an intermediate post
£2 for the particular clamping device shown in
these ?gures, and in Figs. 1 and 2. The apertures
H and H are of a size to accommodate the ends 1U
l5’, l5’ of the strap 15, and are equally spaced
on opposite sides of the post I2 and reversely in
clined as shown so that the strap ends passed
therethrough and outwardly spread, will each
necting device embodying one form of my pres
have an angular return bend engaging the in
clined edges Ha, llb of said aperture, and said
ends will be de?ected in reverse angular direc
tions as clearly shown. Such angular return
bends are an important feature of my invention

Fig. 2 is a corresponding front view of the gog
gle framings, indicating the strap ends extending
in reverse angular directions clear of the framed
lenses.
Fig. 3 is a separate front elevation, on an en
larged scale, of the strap connecting plate indi
cated in Figs. 1 and 2, the clamping part being
broken away.
Fig. 4 is a cross-sectional view taken on the line
50 4—4 of Fig. 3, and showing a preferred clamping
nut mounted on the post, broken away in Fig. 3.
Fig. 5 is a view similar to Fig. 3, but indicating
the return bend end portions engaged in the an
gular apertures.
55
Fig. 7 is a cross-sectional View similar to Fig. 4,
but indicating the aperture of Fig. 6, for the re
turn-bend end portions engageable therein and r
adjustably held by different clamping means.
In the drawing 5, 5’ indicate a pair of any usual
goggle framings adapted to be held in spaced re
lation by a ?exible connection, which usually is
adjustable, to- space the lenses 6, ii’ to accommo
date the wearer. The drawing indicates projec
tions 7, ‘l’, on the respective framings, having
apertures through which the ends of a connecting
band or strap l5 are passed in known manner,
and my present invention relates to a connecting .15
device for such ends that will engage and ?rmly
hold them together, though it is to be under
stood that my connecting device may be employed
for holding together the ends of head band straps
as indicated in my aforesaid Patent No. 1,876,
77 0, or for the connection of strap'ends employed
for other purposes.
Fig. 6 is a view similar to Fig. 3 but indicating
gagement with the plate when clamped thereto
as hereinafter described, and further the free
ends of the straps extend outwardly at inclina
tions from the bent portions of the straps so as
to facilitate grasping the same, and in addition 45
such extending ends lie substantially tangential
to the outer rims of the framings and can in no
manner extend over the lenses 6, 6' to obstruct
vision therethrough. Non-obstruction of vision
and easy grasping of the ends are particularly of
value in connection with goggle framings as the
connecting band is necessarily of a limited width
and length and adjustment made by workmen
whose ?ngers may be clumsy.
The clamping means shown in Figs. 1 to 5 is in 55

dicated as a screw-thread nut 20 engaging the
threads of post I2, and having a knurled-head 2|
and a seating face 22 to engage the return bends
of the strap ends and press them against the plate
I0. To prevent removal and loss of said nut 20,
necessarily small, the post I2 is shown with a re
duced non-thread extension I3 and head l4, and
the nut provided with a recess 23 to accommodate
the post head l4 and limit outward movement of

device for securing the ends of said strap, com
prising a plate provided with reversely inclined
aperture edges adapted to engage and angularly
de?ect return-bend portions of the respective
strap ends, and means for clampingly engaging 5
said return-bend portions to said plate with the
free strap ends extending in reverse angular di
rections so as to avoid overlying said framings.

As within the spirit of my invention I have
indicated in Figs. 6 and 7 a modi?ed construc
device for adjustably securing the ends of said
strap, comprising a plate provided with a pair
tion having but one aperture 25 provided with
of reversely inclined apertures adapted to en
gage and angularly de?ect adjusted return-bend
portions of the respective strap ends, and means 15
intermediate said apertures for engaging adja
cent return-bend portions of said straps to said
reverse angular edges 26, 26' to engage the return
15 bend portions of the straps in the manner here
tofore described, and said aperture 25 also pro
vides an intermediate portion 21 adapted to re-v
ceive the frustro-conical portion 30 of the headed
stud 3| in a manner similar to that disclosed in
my aforesaid Patent No. 1,876,770, said portion
30 however in the present instance having a re—
duced headed extension 32 permitting only a lim
ited removal to adjust the strap ends, the headed
extension 32 being of such size as to prevent re
moval when the strap ends are in engagement
with the aperture 25. After removal of the strap
ends the stud 3| may be freely removed.
The essential features in both of the above
described embodiments of my invention are the
reversely inclined edges of the plate adapted to
engage angular bends of the strap ends for the
improved non-slipping gripping engagement with
said plate, and for the angular divergence of the
strap end extensions to facilitate easy gripping
of the same and to prevent such ends, necessarily
of a length to provide for adjusting, from pro
jecting outward to overlie the lenses and obstruct
vision through the latter. The clamping means
may be varied as most suitable for the purpose,
.40 but preferably should be so attached to the de
plate with their free ends extending in reverse
angular directions so as to avoid overlying said
framings.
3. In combination with a pair of ophthalmic
framings having a ?exible connecting strap, a
device for adjustably securing the ends of said
straps, comprising a plate provided with a pair
of reversely inclined apertures adapted to en
gage and angularly de?ect adjusted return-bend
portions of the respective strap ends, and a
screw-threaded post on said plate intermediate
said apertures and provided with a limitedly ad
justable nut thereon adapted to clampingly en
gage both said return-bend strap portions to said
plate with their free ends extending in reverse
angular directions so as to avoid overlying said
framings.
