The shoe form 20 illustrated in Figs. l to 5,
inclusive, is of the full form type made from a
35 sheet of Celluloid or other suitable moldable ma
terial and having an integral toe portion 2 l, side
Walls 22 and heel portion 23. The heel portion
23 is formed by the rear ends 24 of the side walls
22 which ends overlap and are connected by a
40 rivet 25 located substantially midway between
the top and bottom of the form. The side walls
terminate in bottom flanges 26 connected at the
toe portion 2l by a cross brace 21 in any well
known manner.
45
Longitudinally extending corrugations 28 are
formed in the surface of the side walls and toe
,portion thereby stiffening such surfaces and in
creasing their resistance to compressing or bend
ing forces. In the base of _the corrugations are
50 formed apertures 29 through which air can pass
between the inner and outer surfaces.
The form described above is particularly adapt
ed to be inserted into shoes for the purpose of
are substantially in alignment and are connected 25
by a leaf hinge 31. The heel portion 33 can thus,
as indicated on Fig. 7, be swung relatively to the
toe portion and side walls unit. In the toe
portion 3| and side walls 32 may be provided
longitudinally extending corrugations 38 in which 30
are formed apertures 39.
The form 30 may be used either as a shoe form
which is inserted into a shoe like the form 20 for
the purpose of plumping out and supporting the
walls of the shoe or as a means for fitting lasts 35
and shoes like the form disclosed in my Patent
No. 1,734,203, dated November 5, 1929, the last
or foot being inserted into the form.
The mov
able connection of the heel portion 33 to the
toe portion and side walls is of particular ad- 40
vantage in either case.
When the form is inserted into a shoe the heel
is raised slightly as shown in Fig. 7 to decrease
the length of the form. After the toe portion has
been set in position in the toe of the shoe the 45
heel portion is seated in the heel of the shoe
against the sole and heel counter. In removing
the form the heel portion is raised so that the
form can be easily removed by the operator.
When the form is to be slipped over a last or a 5o
foot the heel portion is swung down, as indicated
in dotted lines on Fig. 7 and raised to the normal
position indicated. in full lines on Fig. 7, after
plumping the walls thereof out to the normal , the last or foot is fully inserted. It will be under
55 condition and holding them in such condition. stood that the corrugations 38 of forms intended 55

to be used as fitting means, will be either omitted
or, raised instead of depressed.
While certain embodiments of this invention
have been shown and described it Will be under
stood that the invention is not limited thereto
and that other embodiments may be made with
out departing from the spirit and scope of the
invention as set forth in the following claim.
I claim:
A shoe form comprising a toe portion, side Walls
and a heel portion, said heel portion being formed
by rearwardly extended ends of the side Walls,
said ends overlapping and means intermediate
the top and bottom of the form for joining said
overlapping ends While permitting relative rock
ing thereof to decrease the Width of the shoe form
at the base of the heel portion, said means com
prising a rivet passed through both said over
lapping ends.
