Thepresent invention pertains to a novel device
for softening the box toes of shoes. The principal
object of the invention is to provide a simple, in
expensive and e?icient device of this character
supported on a foot 2.
having safety features preventing the develop
paratively broad across the front in comparison
ment of excessive steam pressure and also hav
with the width at the ends as may be seen in
Figures 1 and 2. The top and bottom are rounded
outwardly across the sides as indicated by the nu
merals 3 and 4. In the lower rounded portion 4
is an electrical heating element 5, inserted
through one of the narrow ends and ?tted ex
ternally with a control switch 6.
On the front side of the receptacle a pair of
openings 1 are formed in the rounded portion 3.
These openings are substantially semi-circular
in order to receive the toe of a shoe, as illustrated
in Figure 4 and described in detail below. Along
the bottom edge of each opening are formed a
number of spaced teeth 8 standing up from said
edge and also projecting outwardly therefrom as
ing conveniently adjustable supports for the lasts
carrying the shoes to be treated.
V'I'he device comprises essentially a receptacle
10 with means for supplying or generating steafn
therein. ‘The receptacle has one or more open
ings‘of proper shape to receive the‘ toe of the
shoe. - At the lower edge of each opening are pro
vided spaced parallel teeth which permit escape
15 of steam notwithstanding the insertion of the
shoes in theopenings. In one stage of the oper
ation, the toe of the shoe is wrapped in a cur
tain and inserted in the opening. In order to pre
vent blocking of the interdental spaces by this
curtain, the'teeth project forwardly from the re
ceptacle so that escape means is available be
tween the projecting portions of the teeth al
though the front ends of the spaces may be cov
ered'by the curtain.
' In) the preferred embodiment, water-is supplied
to the bottom of the receptacle from an inverted
water bottle ?tted with a level control cup in the
usual manner. The water is converted to steam
by an electrical'or gas heater within the re~
301 ceptacle.
The invention further includes supports for the
lasts carrying the shoes, with means for adjust
ing the position of these supports vertically and
horizontally with respect to the receptacle. There
35 is also a convenient support for the aforemen
tioned curtain.
Outlet slots extend from the openings to pro
vide an additional means for relief of excessive
steam pressure. The slots are normally closed by
use of like characters which are employed to
designate corresponding parts.
The body of the device comprises a receptacle I
This receptacle is com
may be seen in Figures 4 and 5.
On" the forward wall of the receptacle I- are
mounted a pair of spaced, vertical‘ guides 9 in
which is slidably mounted a fork ID. The latter
is secured in adjusted’ position on the receptacle
I by a headed bolt I I engaging a disc I2, the bolt
being threaded into a boss I3 formed integrally
on the inner front wall of the receptacle, as il
lustrated in Figure 1. At the upper end of the
fork I 0 is formed another boss I4 into which is 30
screwed a stem I5 extending forwardly from the
receptacle I.
A collar I6 is slidably mounted on the stem I5,
and from the collar extends a horizontal cross
arm IT in both directions. The ends of the cross 35
arm carry yokes I8 disposed directly beneath the
openings 1 and adapted to support shoe lasts, as
will presently appear. The position of the sup
ports I8 on the stem I5 is adjusted and secured
40 a cover which is manually movable to an open
by a set screw I9 in the collar I6. It will be evi
position and also held down by a spring which
permits automatic lifting of the cover under ex
cessive steam pressure.
The invention is fully disclosed by way of ex
45 ample in the following description and in the ac
companying drawing in which
Figure 1 is a side elevation of the device;
Figure 2 is' a front elevation;
Figure 3 is a detail perspective view of the
dent that the bolt I I permits Vertical adjustment
of the yokes I8 in addition to the horizontal ad
justment along the stem I5.
At the other side of the receptacle I is a yoke
20 having a perpendicular fork 2I extending from 45
one end thereof. At the fork, this device is held
to the receptacle by a bolt 22 entering a boss 23
formed integrally within the receptacle. The
sides of the yoke 20 are ?tted with rubber sleaves
24 between boss 24’ to provide a cushioned sup 50
port for a water bottle 25 mounted invertedly
therein, as illustrated in Figure 1. The neck 26
of the bottle enters a conventional level cup 21
supported by pipes 28 leading to the bottom of
the receptacle I. The cup 21 is of a well known 55
50 water bottle support;
Figure 4 is a detail vertical section at the
upper end, and
Figure 5 is a detail perspective view at the
‘upper end.
Reference to these views will now be made by
construction permitting a water depth of about
1 inch therein, and a corresponding water level in
the receptacle l. The water level in the cup and
receptacle is determined by the position of the
bottle neck_26 which is adjustable by means of
the fork 2| and bolt 22.
Slightly above the openings 1 and between
them is formed a short stem 29 extending from
the forward wall of the receptacle. Through the
10 stem 29 is passed a horizontal rod 30 for a pur
pose which will presently appear. The rod is
held rigidly by a set screw 3|.
In the upper forward wall of the receptacle are
formed passages 32 extending from the tops of
15 the openings 1 and covered at their upper ends
by a cover plate 33.
bolt. Lugs 36 are formed on the ends of the
20 plate 33 whereby the latter may be turned to un—
cover the slots 32 to the desired extent.
A vertical vent tube 31 extends upwardly from
the lower portion of the receptacle l to a point
above the usual water level therein. At the bot
25 tom of the receptacle is provided a drain cock
38 for emptying. It will be understood that the
electric heating element 5 may be replaced by a
gas burner in the nature of a perforated pipe
occupying the position of the heating element
30 shown.
In the operationrof the device, the box toes to
be softened are inserted in the openings 1 in
which they ?t, as shown in Figure 4, the shoes
being carried on lasts (not shown) supported on
the yokes [8. The water heated in the receptacle
I produces steam which envelopes the toes and
thereby softens them. Within the receptacle
and beneath the openings is formed a de?ector
plate 39 integral with the receptacle at the ends
40 but spaced from the side walls as indicated by the
numeral 40 in Figure 4. This prevents the major
portion of the steam from striking the sole of the
’ shoe and induces a circuitous path which is more
favorable for the desired action.
When the leather becomes partly softened, the
shoe is Withdrawn, and a canvas curtain 4! hang
ing from the rod 30 is thrown across the open

too much heat, further relief may be provided by
opening the cover 33 as previously described or 10
by the automatic lifting of the cover as permitted
by the spring 35.
Although a speci?c embodiment of the inven

be understood that various alterations in the 15

parting from the scope of the invention, as in

is held down by a coil spring 35 surrounding the

vening spaces for escape of steam. Even if the
curtain hangs downwardly across the front ends
of the teeth, there is still an outlet from the in
tervening spaces because of the forward projec
tion of the teeth from the front wall of the re
ceptacle, as previously set forth. If however,
the steam pressure becomes excessive or there is
The shoe is again inserted, wrapped in
the curtain, for further treatment.
Neither the shoe itself nor the shoe wrapped
in the curtain can entirely obstruct the opening
dicated by the appended claims.
