SHOE STRETCHER
Frank Cirelli, Philadelphia, Pa.
Application January 27, 1937, Serial No. 122,641
5 Claims. (Cl. 1.2_128.5)
This invention relates to shoe stretchers, par
ticularly to that kind thereof which is adapted
to lift or stretch upward the toe portion of the
shoe, relative to the sole.
5
One of the objects of my invention is to pro
vide an attachment rto the ordinary broadening
shoe stretcher, or that kind thereof which
stretches the shoe sidewise, having the attach
ment adapted to raise the toe portion of the shoe,
10 as the stretcher expands sidewise.
A further object is to provide a metal shell
formation adapted to ñt over the top of an or
dinary widening shoe stretcher, having the shell
pivoted at one end to the stretcher, with the
15 lower side» edges of the said shell shaped to func
tion in cam relation with the upper side faces
of the said stretcher, and thus form an inexpen
sive and serviceable attachment to an ordinary
shoe stretcher, adapting the same to stretch
20 shoes vertically, as well as horizontally.
Another object is to so form the said metal
shell as to hav-e a front hooded portion for main
taining the contour of the toe cap of the shoe,
while it is being stretched vertically.
A further object is to so form the said metal
25
shell that it will operate more against the :tor
ward top portion of the shoe, than it does against
the instep.
With these and other objects which will here
30 inafter appear, my invention resides in certain
structure one embodiment of which is illustrated
in the drawing, is hereinafter described and its
operation is explained. What I claim is set forth.
Figure l is a side elevation of a shoe width
stretcher, having my attachment fitting over it
and pivoted thereto.
Figure 2 is a front elevation of the stretcher and
attachment shown in Figure 1.
Figure 3 is a top plan of the stretcher and
40 attachment shown in Figure 1.
Figure 4 is a section taken on the line 4_4, of
Figure 3.
Figure 5 is another side elevation of the stretch
4
er and attachment shown in the other figures,
but here shown with the stretcher partly ex
panded, and the attachment partly raised by the
same.
Figure 6 is a section taken on the line 6_6, of
50 Figure 5.
Figure 7 is another side elevation of the stretch
er and attachment, but here shown with the
stretcher expanded more than is shown in Figure
5, and having the pivoted attachment raised high
55 er than shown in Figure 5.
Figure 8 is a section taken on the line 8_8, of
Figure 7; and
Figure 9 is a perspective view of the lifter shell
attachment.
An ordinary form of shoe stretcher Iû is shown
in the figures. This stretcher has two body halves
II and I2, engaging the rod-like projections I3,
of the trunnion nut I4, at the holes I5. An inner
cam channel I6, having part in each body half,
is formed for engagement with the usual wedge 10
head I1, which is swiveled in connection with
threaded rod I8.
This rod I8 is in threaded en
gagement with the nut I4 and has a turning han
dle I9, fixed to its end. Suitable means, not here
shown, are used to hold the heel ends of the body 15
halves II and I2, together.
Fitting loosely over the top face 20, of the
stretcher` I0, when closed, is the metal shell 2|,
having a front over turned portion 22, adapted
to fit over the toe end of a closed stretcher. This
portion 22 is so curved, that it will ñt against the
inner contour of the toe of a shoe, when the
shell is pushed up. Extending rearwardly and
integrally, from the front portion of the shell 2l,
are the arms 23.
The horse shoe shaped lower 25
edge 24, of shell 2l, is rounded transversely at
the side portions 25, and so shaped that it will
function in cam relation to the inclined face
portion 26, of the top face 20, of each, of the
halves, II and I2. While the cam portions 25,
of the lower edge 24, simply lay along the lower
side portions, of the face 20, when the stretcher
I0 is closed, they are so shaped and positioned,
that they will be in cam relation to the stretcher
face 20, as the front end of the stretcher is caused
to spread open, as for side stretching of shoes.
The shell 2I is pivoted near the top of theheel
portion 21, of the stretcher, by having screws 28,
pass loosely through holes 29, at the ends of the
arms 23, and also through the washers 30, into
ñxed relation with the heel portion 21, of the
stretcher I0. It will be noticed that the curved
edge 3l, of the shell 2|, is positioned consider
ably forward from the ends of the arms 23, leav
ing an open space 32, so that when the stretcher 45
occupies a shoe, that portion of the shoe directly
over this space 32, will not be materially stretched
by the up-moving shell 2|.
In operation, a closed stretcher I0, is forced
well forward into a shoe to be stretched, so that
the front portion 22, of the shell 2|, comes di
rectly under the front toe portion of the shoe.
Next upon so turning the handle I9, that the
wedge head I1 moves forward against the sides
of the channels I6, causing the front, or toe end, 55

of the stretcher to spread open. As the for
ward part, of the top face 20 engages the side
edge portions 25, a further opening of the
stretcher halves ll and l2, causes these edges to
ride up on the inclined face portion 26. In Fig
ures 5 and 6, the section line 6_6 is drawn across
a point 33, of the line contact between the edge
portion 25 and the face 20, of the stretcher, for
the particular relative positions of the shell and
l. A shoe stretcher including in combination
a stretcher body, of two longitudinal halves held
together at a point, at their rear ends and adapt
ed to be spread in angular relation from said
point, means for spreading said halves in angu
lar relation, a downwardly and outwardly in
clined upper face to each of said halves, a shell
pivotally connected with the rear of said body
near said point, and extending forward to lie
stretcher shown in these figures for a partly ad
vanced position of the wedge head l1. As the
wedge head I1 is still further advanced to some
loosely over said faces, cam edges at the sides
of said shell, shaped and positioned to come in
cam relation to said inclined upper faces, and as
such position as `is shown in Figure "I, the con
tact between the edge portions 25 and the in
15 clined face portions 26, moves rearwardly, so that
said halves are spread in angular relationV to
cause said shell to swing upward upon its piv
oted end, near said point to lift the front por

on the edge portion 25. Through this point 34
tion of a shoe it may occupy.
2. A shoe stretcher made in accordance with
in Figure 7 is drawn the section line 8. As the
wedge head l1 causes an increased spreading of

ing over the forward end of said body, to pre

directly into contact with, inside the shoe. The
rounding over of the toe portion 22, of the shell
2 I, preserves the rounded appearance of the toe,
of the shoe. Reversing the turning of the rod

well as sidewise.
If it is desired to stretch the forward part
35 of the shoe more upwardthan sidewise, then a
lug 2 Ib, is placed upon the front part of the shell
2|, so that the pin 2 Ic of the lug 2 Ib, ñts into the
hole Zia. When the shell 2l, so equipped with
the lug 2lb, is used inside the shoe and shoved
40 into» position, as the wedge head Il begins to
move forward, a concentrated pressure from the
lug 2lb immediately takes place, particularly be
fore any or only a little side stretching takes
place. An assortment of various shaped lugs
45 2lb, can be provided and various holes Zia, in

oted at the screws 28', lifts higher and causes an

various advantageous positions on the shell 2|,
can be made, thus giving the person using the
stretcher a'variety of positions to select from in
applying a concentrated pressure upward by the
lifting of the shell 2|.
Inasmuch as changes in the one embodiment
of my invention herein shown and described can
be made without departing- from its spirit and
scope, I wish to include all forms thereof which
come within the purview of the following claims.
I claim,

tudinal halves from a point, at the rear end of
said stretcher, where said halves are held toi
gether, and which has a downwardly and out
wardly inclined upper face to each of said halves, v
a curved shell overlying the forward end of said
faces, and pivoted at its rear end to the rear
portion of said stretcher near said point, said
shell terminating at its sides in cam edges shaped
and positioned to come into cam functioning re
lation to'said upper faces as said halves are
spread in angular relation to cause said shell to
lift upward while swinging upon its pivotal con A3,5
nection with the rear of said halves, as said
halves of said stretcher spread.
'
4. In connection with a shoe stretcher which
operates by the angular spreading of its longi
tudinal halves held together at a point near their :40
rear ends, and which has a downwardly and out
wardly inclined upper face to each of said halves,
a curved shell with side edges, said shell over
lapping and conforming to the shape of said faces
when they are together and the stretcher closed,
the edges of said shell being formed to come in
cam relation to said faces, when said stretcher is
spread, means for pivoting the rear end of said
shell to the rear portion of said stretcher, near
said point, said shell having its rear mid-por
tion cut away forming side arms, which extend
rearwardly and are connected with said means.
5. A shoe stretcher made in accordance with
claim 1, having in addition a releasable lug po
sltioned on top of said shell.
