suitable for this purpose which gives the desired
support and cushioning elfect.
The upper surface of the base Iû, adjacent its
marginal edge, is skived as at I4 so that the
5 upper surface converges towards the lower sur
face and tapers off to a thin edge. The base I0 is
formed with a longitudinally extending `slot I5
having longitudinally spaced laterally extending
notches I E and I'I in its opposite side edges which
0 are disposed in transverse alignment.
The un
dersurface I2 of the pad element II is adhesively
or otherwise secured to the upper surface of the
base IQ throughout its area except for a medial
portion indicated by the broken line I8 in Fig. 1
5 of the drawings, and which unsecured portion is
located over and adjacent the slot I5.
In order to provide means for detachably con
necting the arch support A tol the sole B o-f the
shoe, an anchoring device is employed which is
20 designated generally by the reference character
C. The anchoring device includes a stud having
a threaded shank I9 which depends from a rela
- tively thin head 20 which is positioned between
the upper surface of the base I 0 and the un
25 secured medial portion I8 of the pad element II
and which is introduced thereto by flexing or
bowing the base I0 laterally and downwardly.

washers or similar elements 22 before the stud
is engaged with the sleeve 26.
In the form of the invention illustrated in
Figs. 5, 6, '7 and 8, D designates generally the
inwardly from adjacent its marginal edge. The
plate is formed substantially centrally thereof
with a longitudinally extending slot 3B and has
outwardly extending notches 3T opening into the
slot and spaced about the edges thereof, the
notches on the opposite longitudinal edges being
staggered with reference to each other.
20
A cover plate 38 of sheet metal or an equiva
lent fiexible resilient material is spot welded or
otherwise secured to the upper surface of the base
plate 3f: at laterally spaced points 39 lying on
opposite sides of the slot 3B and substantially in
termediate the length of the base plate. The

30 to the shank I9 and which key pins and shank
extend through the slot and protrude down
wardly from the base IIJ. Obviously under
this arrangement the shank I9 may be ad
justed longitudinally with reference to the arch
The arch member D also includes a pad ele
ment @il which is shaped to conform generally
to the shape and size of the base plate 34 and
5 support A while at the same time the arch sup
pad being thicker at the central portion and de
clining into a thin edge. The pad element 48 is
superimposed upon the base plate 34 and cover
port may be turned with reference to the shank
I9 to obtain various angular adjustments. After
the shank and arch support A have been set in
the relative position desired, a rigid washer 22
40 preferably of metal is applied against the under
side of the base lll, the washer being provided
with a central opening 23 for receiving the
threaded'shank I9 and eccentric openings 2li to
receive the key pins 2 I. A lock nut 25 is thread
45 edly engaged on the shank I9 and tightened
against the washer to clamp the base adjacent
the slotted portion between the head 20 and the
washer.
The anchoring device further includes an in
teriorly threaded sleeve 26 which is designed to ,
receive the threaded shank I9 and which is ro
tatably mounted in an opening 21 formed in the
shoe sole B, the sleeve being provided with a
kerfed head 28 which is exposed at the bottom of
55 the shoe for turning the sleeve to draw the shank
I9 and the arch support downward against the
upper surface of the sole, the key pins 2l being
engaged in preformed key sockets 29 opening
60
through the upper surface of the sole.
In use the lock nut 25 is loosened and the
shank I9 is threadedly engaged with the rotary
sleeve 25 and drawn down loosely against the
upper surface of the shoe sole.
T'he user, after
trying and shifting the arch support A to various
» positions, determines the position which properly
and comfortably supports the arch. The arch,
together with the stud, is disengaged and re
moved from the shoe and the lock nut is then
tightenedto retain the arch support and stud in
0 their adjusted relation. The shank I9 is then
reengaged with the rotary threaded sleeve 26
and is drawn into place where it is held in place
by the clamping action of the sleeve. It is, of
course, obvious that pads may be used which

for the purpose and which provides the proper
support and cushioning effect. The arch mem
ber D is completed by a thin sheath 42 of leather
or an equivalent material which completely cov
ers the upper surface of the pad element dû and
extends beyond the marginal edge thereof and
which has a lower ply 43 underlying the base
plate 34 and provided with a longitudinal slot
¿Il which exposes the slot 36 and notches 3l of
the base plate. The marginal edges of the sheath
are skived to a thin edge 45.

adjusted vertically in the bushing by means of a threaded stud 'H having' a thinY disk like head 'l2
_ a screw 54 which cooperates with the internal
' threads of the stud. The screw 54 is formed
at its lower end with a iiange 55 which is lo
cated between the lower end of the bushing and
a bottom plate 56 countersunk in the lower sur
face of the sole E. The screw is provided with
a kerfed head 5‘! which is exposed by a central
opening 6l in the bottom-plate 56 whereby the
screw is swivelly mounted and is adapted to be
turned from the outside of the shoe by an imple
ment engaged with the kerfed head 51. The
“ screw, in addition to serving as a means for se
curing the stud and arch member D in place, is
utilized for adjusting the elevation of the arch
member. In order to lock the screw in its ad
justed position, a set screw 58 extends through
an opening 62 in the bottom plate 56V and is
adapted for selective threaded engagement in
threaded openings 59 formed in the flange 55.
The bushing and bottom plate are secured to
gether by rivets 66 which pass therethrough and
through the sole E of the shoe.
In use, the lock nut 56 is loosened and the stud
46 is engaged in the bushing and drawn down
by the screw 54. The arch member D is then
shifted longitudinally or laterally into any one
of the notches 3'! and/or turned to obtain the
desired adjustment after which the screw 54 is
loosened, the stud 46 removed and the lock nut
56 tightened to hold the pad and stud in rela
tively adjusted position. The stud is then rein
serted in the bushing 5l and the screw 54 em
ployed to draw the stud and arch member D
downwardly to the desired elevated position and
finally the set screw 58 is utilized to secure the
screw 54 against accidental turning. Under this
construction and arrangement, it will be appre
ciated that a practical-ly universal adjustment of
the arch support is obtained.
In the form of the invention shown in Figs.
9 to l5 inclusive, F designates generally the arch
supporting member which includes a base 65 of
_the desired contour, which is of generally oval
formation conforming substantially to the region
of the metatarsal arch. The base 65 may be
constructed of leather, rubber or any analogous
` iiexible material which is normally substantially
nat and is adapted to rest upon the upper sur
face of the sole portion G of the shoe. The
member F also includes a pad element 66 which
conforms generally to the shape of the base 65
and is formed with a flat lower surface and a
convex upper surface 6l, the pad being thicker
at the central portion and declining towards its
marginal edge where it merges into the upper
surface of the base 65, the pad element 66 be
ing constructed of rubber, felt or any equivalent
yieldable elastic cushioning material suitable for
this purpose.
The base 65 is formed with a lon
gitudinally extending slot 68 extending from sub
stantially the central portion to a point adja
cent the rear portion thereof, said slot having
at its upper end which is positioned between. the
upper surface of the base 65 andv the unsecured 15
portionì ‘lll- of the‘pad. element 66. The head 12 is
provided with: oneä or more downwardly extending
key pins 13 which. are disposed parallel to= the
stud 'l Ii and which` key pins, together with the stud,
extendthrough the slot and protrude downwardly 20
from the‘loasev 65'. This construction and arrange
ment permits of the longitudinal adjustment of
are arch member F" with reference to the stud
and the turning of the arch member'with reference
thereto to obtain the various longitudinal and 25
angularl adjustments. desired.
In this form ofthe invention supplemental sup
porting elements, designated generally by the ref
erence character H, are adapted to be used which
include a relatively thin base 14 having a longi 30
tudinal extending slot T5 and communicating
notches 'I8 corresponding to the slot 68 and
notches 69 of the base 65 of the main arch sup
porting member F. Each of thev supplemental
supports is providedE with a generally forwardly
directed reduced extension 'Il having on the upper
surface thereof, an auxiliary padl 18 of a yieldable
resilient4 material. Each. of the supplemental sup
porting elements H is adapted to underlie the
main arch supporting member F and the exten 40
sions Tl' thereof arevariously shaped so that they
may’ be optionallyl used to underlie and elevate
various areas of' the forward portion of the main
arch supporting' member where additional ele
vation and support is desired in various regions 45
of the metatarsal arch. As shown in Fig. 9, the
supplemental elements H are located under the
ñrst and» third metatarsals, while in Figs. 13, le
and 15 the elements H for the fifth, fourth and
secondmetatarsal are respectively shown.
After the. stud. ‘H and arch supporting element
F have beeniset in relativev position and the desired
supplemental supporting element or elements H
have been applied, a washer 19 is engaged over
the stud 1I and key pins 'I3 and a lock nut 80 are
employed to bind the parts in set position. `The
stud is then inserted in an opening 8| which ex
tends through the shoe sole G, while the key pins
are engaged in key sockets 82. An interiorly 60
threaded sleeve 83 is rotatably mounted in an
opening 84 in the shoe sole and is adapted to re
ceive the threaded stud 1I which is drawn down
wardly together with the arch supporting mem
ber F and supplemental sup-porting element or 65
elements H. The threaded sleeve is provided with
a kerfed head 85 which is exposed from the bot
tom of the shoe sole to afford means for turning
the sleeve.
In each of the forms disclosed, when the arch 70
supporting element is elevated adjacent the stud
portion, the marginal edges of said support are
flexed downwardly by the engagement of the
foot therewith, while the region adjacent the stud
is ñrmly supported in the elevated position.
