4 Claims. (Cl. 36——'-'71)
This invention relates to arch supports such‘
as are employed in footwear, the principal object
being to provide an arch support including means
‘whereby the curvature of the arch may be ad
justed to meet foot requirements.
Another important object of the invention is
to provide an arch support capable of being. read
ily transferred from one shoe to another, so that
a person may use the same support in several
pairs of shoes.
Still another important object of the invention
is to provide an arch support of ?exible construc
tion and capable of being adjusted to various
curvatures to accurately ?t and support a foot
arch with but a minimum expenditure of e?ort
on the part of the adjuster.
Various other important objects and advan
tages of the invention shall become ‘apparent to
the reader of the following description.
In the drawing:
Figure 1 is a top plan view of the arch support.
Figure 2 is a longitudinal sectional view taken
on line 2-2 of Figure 1.
Figure 3 is a bottom plan view of the arch sup
Figure 4 is a transverse sectional view taken on
line 4-4 of Figure 2.
Figure 5 is a top plan view of‘ the adjusting

end of the spring 8 ?xed adjustably with respect
to the corresponding end of the plate 6.
On the spring 3 at the intermediate portion
thereof, and secured thereto by’ rivets H isan
elongated block l2 having transverse grooves I3
therein with which a spring detent member I 4
is adapted to cooperate.
The opposite end of the adjusting spring 8
has an elongated slot I5 therein through which
a bolt I6 is disposed like the bolt l 0 in the manner
shown in Figure 2, this bolt I6 being also dis
posed through a longitudinal slot H in one end
portion of the detent M. A lock spring washer
15 I8 is interposed between the slotted end of the
adjusting spring 8 and the securing nut on the
‘lower end of each bolt l0 and I6, as is apparent
in Figure 2.
As disclosed in Figure 2, the end portion of the
20 spring detent l4 opposite to its bolted end is dis
posed over the transversely grooved block l2 and
has a downturned groove-entering lip l9.
Now assuming that the person who intends to
wear the arch support purchases the same at a
store. In most instances it will be necessary for
him to adjust the arch and this is accomplished
very easily at either or both ends of the support.
The bolt I6 is readily loosened, thus freeing the
slotted end of the adjusting spring 8 and the
slotted end of the detent It. The support may

disposed downwardly through the openings in or

part of the adjuster.
It can also be appreciated that the device while
being inherently yieldable, will always react to
normally maintain its supporting form and
height, to the end that the foot arch will always
have the same support although yieldability ex

the concave side of said member, an elongated
wherein said member and said plate are pro
vided adjacent their ends with bolt-receiving
openings, said openings being in alignment with
each other and with said elongated slots of said
spring member, and a bolt at each end of said
member and passing through said openings,
whereby said member, plate, and spring member
are secured together.
4. In an arch support having a leather mem
adjusting spring member secured to said metal 10 ber, a plate member secured to said leather at
plate, said spring member being provided at each
opposite ends thereof, and angadjustable spring
of its ends with elongated longitudinally arranged
device secured to said plate, said adjustable spring
