SPRING FOR SHOE FORMS
Louis W. Reinhardt, Brockton, Mass, assignor to
George E. Belcher Company, Stoughton, Mass,
a corporation of Massachusetts
Application July 25, 1935, Serial No. 32,986
5 Claims. (C1. 12——128.4)
My present invention relates to improvements
in hollow shoe forms.
cated at I in Fig. 1 as applied to a hollow shoe
_ form 2 described in detail in my co-pending ap
The widespread demand for a less expensive
shoe form has resulted in many attempts to
5 provide such a form that will satisfactorily meet
all the requirements as to appearance’ and.
strength. In my co-pending application, Serial
No. 1,271 ?led January 11, 1935, I have shown a
plication, Serial No. 1,271. The form 2 is shaped
to provide the desired internal support for the
. novel hol1ow shoe form that provides the essen
resulting from the disposal of slackage developed
during the molding of the form 2. The strength
10‘ tial ?rm, well ?tted internal support for the shoe
that meets that demand.
The hollow shoe form shown in my co-pend
ing application, Serial No. 1,271, is molded from a
textile blank such as presized buckram and is
1-3 characterized by a substantial sole ?ange having
reenforcing plaits in the forward portion de
veloped in molding operations, which plaits are
disposed in preservation of the line of contact of
adjacent ?ange surfaces with the inner sole.
20 A spring bridges the ?ange and ensures the de
sired lateral resiliency.
While such a form may be made of light stock,
it is of great strength and its resiliency permits
its insertion into the toe cavity to effect a con
25 cealed- reenforcement. Such a form, however,
emphasizes the problem of removing these forms
| because of the tightness of the ?t and the char
acter of the stock from which they are made.
This problem is obviously present to some extent
30 with all acceptable forms, but varies with the
effectiveness of the support rendered and the
type of shoe in which it is to be used. Of the
many types and styles of shoes, women’s shoes
not having a tongue well illustrate the dif?culty
35 of dislodging a concealed tight ?tting form.
I have solved this problem by providing a novel
spring’, which, while exerting the necessary lat
eral pressure to ensure the tight ?tted support
for the toe portion of a shoe is so formed that
40 it may be compressed to free the form when
properly contacted by an extractor.

In the accompanying drawing I have illus
trated my novel spring as applied to a form made
in accordance with the invention disclosed in my
45 co-pending application, Serial No. 1,271. In the
drawing:
Fig. 1 is a bottom view of such a form with
my novel spring attached.
Fig. 2 is a plan view of a shoe supported by
50 such a form.
Fig. 3 is a vertical section through such a shoe
and hollow form, and
Fig. 4 represents a suitable compressive ex
tractor.
55 I have shown my novel spring generally indi
toe portion 3 of a woman’s shoe.
Such a form is molded from a presized textile
blank and includes an integral sole flange 4 hav
ing upturned ends 5. I have indicated at 6 plaits
of the form 2 is such that it may be made of
light stock giving the form 2 an inherent re
siliency which with the addition of a spring
renders the form 2 extremely well ?tting.
While a form thus made is acceptable as far
as strength and appearance are concerned, its
withdrawal from a toe cavity is di?icult as will
be appreciated from Fig. 3. For that reason, the
wire spring I includes a U-shaped head 1. and
diverging end portions 8 terminating in inturned
loops 9 which permit the ends of the spring to be
securely anchored as by eyelets [0 to the flange
4 at substantially the widest part of the form 2.
The head ‘I is preferably upturned as may be
seen in Fig. 3 and it extends forwardly to a point
near the front of the form 2.
The extractor H includes an upwardly bent
portion l2 and a handle indicated as at IS. The
portion l2 has a rounded end which permits the
extractor to be used in lodging the form 2 in the
toe cavity 3.
Near the rounded end of the extractor H is
an aperture M of a size suilicient to permit its
free passage over the head ‘I to permit the com
pressive contact of the diverging portions 8 of
the spring I as the extractor H is withdrawn.
When it is desired to remove a form from a
shoe, the extractor H is inserted therein sub
stantially as far as possible. Because of the
rounded end of the extractor II and the shape
of the form, the aperture I4 is properly aligned
with the head ‘I of the spring I. The aperture
M passes over the upturned head ‘I as the ex~
tractor II is withdrawn and is guided to con
tact and compress the diverging portions 8 to
draw the ?ange 4 inwardly and free the form 2
as indicated in Fig. 2 so that it may be removed
with the extractor II.
I am thus able to provide a spring that may
be used with any conformablesupport and that,
while serving to ensure the well ?tted support,
is adapted to be used to free such a form so
that it may be removed very easily.
In accordance with my invention, I am able
to provide a hollow shoe form improved as to
2

appearance and as to the support rendered that
fully satis?es all requirements.
What I therefore claim and desire to secure
by Letters Patent is:
l. A hollow shoe form adapted to render a
well ?tted internal support for the toe cavity
of a shoe, a spring bridging said form and being
adapted to ensure said support when said form
is lodged in said toe cavity, said spring including
10 a U-shaped head lying near the front of said
form and diverging'ends anchored to opposite
portions of said form, said diverging ends being
adapted to be compressed upon retractive en
gagement by an extractor and said head being
15 upturned to facilitate said engagement whereby
3. In a hollow shoe form adapted to furnish
support for the toe cavity of a shoe, a spring
bridging said form and tightly forcing said form
against the walls of said cavity, said spring in
cluding inturned arms anchored at their ends
to opposite sides of said form and united ad~
jacent the toe part of said form by an elon
gated portion adapted to center and to guide
an extractor over said arms to position to re
tractively compress the same to permit removal 10
of said form from a shoe.
4. In a hollow shoe form adapted to furnish
support for the toe cavity of a shoe, a spring
bridging said form and tightly forcing said form
against the walls of said cavity, said spring in 15
said form may be readily removed.
2. A shoe form comprising an integral upper
and sole ?ange molded from a cementitiously
cluding inturned arms anchored at their ends
to opposite sides of said form and united by a
presized textile blank, said sole ?ange being of
and to guide an extractor over said arms to po
sition to retractively compress the same to per 20
mit removal of said form from a shoe.
5. In a hollow shoe form adapted to furnish
20 substantial width and including in its front por
tions reinforcing folds constituting residual
slackage of the ?ange stock developed in the
molding of said form, said folds being disposed
to permit the contact plane of said ?ange and
25 the inner sole surfaces to be determined by ad
jacent ?ange surfaces, a transverse bow shaped
spring anchored to said ?ange to cooperate with
said form in establishing a well ?tted internal
support for a shoe, the bow of said spring be
30 ing forwardly disposed and shaped to be com
pressed by retractive contact on each side of
the center of said spring to permit said form to
bev readily removed.
r
U-shaped elongated portion adapted to center
support for the toe cavity of a shoe, a spring
bridging said form and tightly forcing said
form against the walls of said cavity, said spring 25
including inturned arms anchored at their ends
to opposite sides of said form and united by an
upturned elongated portion adapted to center
and to guide an extractor over said arms to
position to retractively compress the same to 30
permit removal of said form from a shoe.
