to the lens ?rm and substantially rigid to prevent
looseness and play during the use of the mount
ing and yet be of such a nature asto relieve
20 shocks and strain .on the lenses when the glasses
are dropped or roughly handled and that will

10 ings to the lenses so that the said lens holding
means will-have relatively free resilient action
and yet be prevented from becoming loose and
wabbly during use. One of the di?iculties has
been that, in most instances in the past, the
15 means employed for resiliently taking up the
looseness and play of the lens holding means on
the lens depended upon the support of a rigid
backing shoe and, due to the restricted size of
such devices, were not su?iciently durable to
20 produce the most desirable structure, that is, the
resiliency of the resilient means would soon play
out or the solid backing shoe supporting said
resilient means would become bent or distorted
and permit the parts to loosen and move out
25 of aligned relation with each other during use.
This was due primarily to the fact that, inmost
instances, the rigid ‘backing shoe, in order to
function properly, had to be ?tted with the re
silient-means so that it would impart a crimping
80 action adjacent the opposite ends thereof when
the lens holding means was moved on the lens.
This crimping action was adapted to cause the
straightening of the resilient means, after such
?exing, to return the parts to their initial aligned
35 relation with each other. It is quite apparent that
if the rigid backing shoe became bent during use,
lens holding means extends and which is headed
over to secure the sections to said base. The
different sections may be varied in resiliency or
may be of the same‘resiliency, as desired, with 15
the section 9 more rigid than the section ‘III and
the section III more rigid than the section II.
The lens holding means in this instance is of such
a nature that it may be moved upwardly and
‘downwardly in the plane of the lens about the 20
connecting means ‘I as a center and provides free
action shock and strain absorbing meansin both
.
directions.
The resilient means IS in this in
stance also takes up’ the looseness and play of the
connecting means and also acts as shock absorb
ing means. It also tends to maintain the lens
holding means in proper aligned relation with
the lens, that is, if de?ected upwardly or down
wardly about the connecting means ‘I; it will al
ways tend to return to its initial set.
30
The base of the bifurcation in the rear of the
resilient sections 9, III and l l and to which the
said resilient means is attached by the projection
i2 is relatively narrow in the direction of the
length of the resilient means and permits of a
long and free ?exing action of said resilient
the device would not function properly.
It, therefore, is one of the primary objects of
this invention to obviate the above defects by
40 eliminating the usual rigid backing shoe of lens
means in this direction during use. The conven
said backing shoe with resilient backing means
which will allow the lens holding means a greater
pivotal movement on the lens and provide freer
45 acting and more durable shock absorbing cushion
and I0 so as to provide a wider range of ?exibility.
The narrowing of the base of the bifurcation also
increases the normal pivotal movement of the
lens holding means on the lens thereby allowing
more ?exing action of the resilient means.
The upper and lower edges l3 and it of the
base of the bifurcation and the free ends I5, I 6

formed relatively straight transversely thereof so
as to provide substantial line contact with each
other and with the edge of the lens when .the lens
holding means is moved about the lens connecting
holding means of this character, and to replace
ing means.
A further object is to increase the normal re
silient easing off action of the resilient means
and to increase the tendency of said resilient
50 means to return the parts to their initial set after
such easing oif.

Another feature is that of providing a novel

means to their supporting means so that the said

surface in a direction longitudinally of the re

of the resilient means being displaced sidewise
30 out of relation with each other during use.
‘ The portions l9 pressed into engagement with
the beveled end walls 20 provide means for an
choring the resilient means in the direction of
?exing and thereby provide a positive and dura
ble attachment. This method of attaching the
resilient means to the bodyportion of the lens
holding means enables the spaced lens face en
gaging portions 4 to be adjusted to any desired
spaced relation with each other, independently of
40 the resilient means, to be ?tted to lenses of vary
ing thicknesses without danger of having the re
silient sections move out of aligned-relation with
each other as would be the case if a round pin
were used and the inner walls of the spaced face
engaging portions 4 were depended upon to hold
the resilient sections in alignment. It is quite
obvious that with the latter structure,~if the space
between the lens-face engaging portions were in
. creased, as happens when the lens holding means
to
isvi'itted to a thick lens, the inner walls of said
face engaging portions would move away from

of Fig. II, only in this instance, instead of having 25

edge of the lens it has a curved face providing a
line contact transversely of the edge of the lens,
which edge in the'plane of the lens, is free to rock '
as the lens ‘.holding means is moved about its 30'
.point of attachment to the lens. In this instance,
the body portion of the lens holding means is
beveled rearwardly as indicated at 25 and 26
from points adjacent the opposite sides of the
pin member 21 so as to provide a wider range of
?exing of the resilient means. In this instance, .
the resilient section 28 forming the ~ backing
means for the resilient section 29 is preferably
cupped, as shown in Fig. VIII, in a direction‘
transversely of its longitudinal axis to increase 40
the rigidity of said resilient‘ section; The object
of this cupping is to provide means which during
the securing of the various resilient sections to
the body portion of the lens holding means by
the pin member 21 is adapted to prevent a pos 45
sible straightening of said resilient means.
Although the section 28 tends to prevent the "
straightening of the resilient sections 24 and 29

holding means, it provides resilient backing. 50.

I relation with each other during use.
The various resilient sections 8, l0 and II are
curved during the forming thereof so as to en
gage the edge of the lens only adjacent their
ends with the central portions thereof adapted
60 to be held in spaced relation with the lens. Dur
ing the securing of the various resilient sections
to the body portion 2, some dimculty was en
countered in having the sections become straight
ened to such an extent that they would not prop—
erly ?t the edge of the lens. To overcome this
tendency of the resilient members to straighten
during the attachment thereof to the body por
tion 2, the said body portion is cupped at its at
taching face 22 in the direction of the longitudi
70 nal axis of the resilient means to a curvature
whose radius is less than the radius of curvature
of the edge of the lens at said location but sub
stantially equal to the curvature desired of the
resilient means. It is quite obvious that when

with upcurvedends 23 the said ends may be
so shaped as to mave substantial surface con
tact with the edge of the lens, that is, the said ‘
ends may be so formed as to have a substantial
portion thereof in intimate surface contact with 60
the edge of the lens. This arrangement would
provide means' for distributing possible strain
which might be introduced at said locations dur
ing the ?exing of the resilient means over a
greater area thereby providing a more positive
6.5
cushioning effect. It is apparent, however, that
the line contact set forth in connection with
the structure shown in Fig. 11 as compared with
the prior-art point contact of the resilient means 70
with the edge of the lens will greatly relieve the
pressure strain at said ends. This in itself
greatly reduces the tendency of the lenses to be
‘come broken due to strain of this nature dur

It is apparent that the spring sections 28 and
29 may also be provided with upcurved ends if
desired.
It will be noted that the distance between the
respective ends l5, l6 and ll of the-various re
silient sections and the distance from the edges
l3 and M from the respective ends I5 01' the
section 9 are all substantially equal. This is 'to
provide staggered line contact supporting ends
10 or edges at equally spaced intervals intermediate
the ends of the resilient section II which during
the ?exing of said section will be successively
brought into action to stabilize the ?exing of
said section throughout its length. The sections
15 9 and I0 resiliently ease off the ?exing of the
section I l and increase its tendency to return to
its initial set after such easing o?. This function takes place in either direction of the ?exing;
in one direction the’ upper sections perform the
20 function and in the other direction the lower
sections perform the function.
It will be noted that the distance between the
ends of the various resilient sections 24, 28 and
29 and the distance between the upper and lower
25 contacting edges 30 and 31 of the lens holding
means with respect to the ends of the section 28
are substantially equal and tend to stabilize the
?exing of the section 24 in a manner similar to
30
the structure shown in Fig. III.
In Fig. IX there is shown another modi?ed,
form of the invention wherein the resilient sec
tions 32, 33 and 34 are connected to the overly
ing portion 35 of the lens holding means by spot
welding, as indicated at 36. In this instance the
35 pin I2 is not used and the resilient sections are'_
not perforated such as is they case when the pin
type connectingmeans is used. It is obvious
that the spot welding method may be used in
‘any of the various structures shown. The spot
40 welding. is accomplished by the provision of a
suitable apparatus of the conventional type hav
ing a contact engaging the springs in the vicin
ity wherein the welding operation is to be per
formed. This integrally joins the sections with
each other and with the overlying portion 35 at
ing aligned slots therein extending in the direc- .
tion of the length of the resilient members and

and being headed over to overlie and secure the
resilient members to the curved surface inter

the adjacent resilient member curved substan

resilient member which is to engage the edge of
the lens will be adapted to engage said edge at 10,

each side of the portion overlying the edge of the
lens and will be free to ?ex throughout the greater
portion of its length during use, the means for
securing said resilient members to the curved 15

silient members in surface contact with each
