SHOE FINISHING MACHHNE
William H. Nutt, Beverly, Mass., assigner to
United Shoe Machinery Corporation, Pater
son, N. J., a corporation of New Jersey
Application October 18, 1937, Serial No. 169,526
9 Claims.
This invention relates to finishing machines in
which means are provided for applying a finish
ing medium such as wax, blacking, or a combina.
tion of the two to the edges of soles of shoes and
is illustrated as embodied in a machine of the
type disclosed in United States Letters Patent No.
1,080,961, granted December 9, 1913, on an ap
plication filed in the name of L. W. G. Flynt.
It is the general practice to apply blacking or
other finishing material to shoe edges by hand
prior to the operation on these edges by edge
4setting tools. This practice involves double han
dling of the shoes by an operator. The finishing
material in liquid form is first applied to the shoe
edges which are then placed in a rack to dry,
after which the edge setting operation is carried
out.
With this practice in view, it is an object of the
present invention to provide an attachment for
edge setting machines which will apply a ñnish
ing medium automatically to sole edges during
a finishing operation, thus saving the time and
labor required for the application of the finishing
medium manually with a brush and also making
for neatness. In the embodiment disclosed, the
finishing medium applying means is located im
mediately adjacent to and ahead of the edge
finishing tools in order that the finishing medium
will be applied to the surface to be ñnished just
prior to its presentation to the edge finishing tool.
In the illustrated machine the application of the
finishing medium is controlled by a work re
sponsive detent Which, in response to pressure by
- the work, releases the finishing medium for con
tact with the work. As a result of this arrange
ment, the work is operated upon simultaneously
by the edge setting tools and the medium applying
means. These operations take place at closely
adjacent points thus providing an arrangement
wherein the steps of applying finishing medium
to the work surface and the operation upon this
surface by the edge setting device are performed
in one continuous uninterrupted operation.
It is a further object of this invention to provide
a work controlled device for automatically ap
plying a solidv finishing medium to the work as it
is presented to the device. In accordance with
, this object, the invention, as illustrated herein,
provides a stick holder in which a stick of finish
ing material such as combined waX and blacking
is normally urged outwardly from the holder, but
which is retained in the holder by a work-re~
sponsive retaining means. When the work is ap
plied to the retaining means, that means is moved
(Cl. 12-17)
to an inoperative position thereby releasing the
stick for engagement with the Work.
While this invention is disclosed as embodied
in an edge finishing machine, it can be used in
other finishing machines or, as to some of its
5
features, by itself and apart from any other
mechanism.
The invention will now be more particularly
described by reference to the accompanying
drawing and pointed out in the claims.

In the drawing,
Fig. l is a side elevation of an illustrative edge
setting machine having the finishing medium ap~
plying device attached thereto;
Fig. 2 is a front elevation of the mechanism l5
shown in Fig. 1; and
Fig. 3 is a view similar to Fig. 2 illustrating
another embodiment of the invention.
The attachment for applying finishing medium
is shown mounted on the head of a machine frame N)
2, only a portion of the frame being disclosed in
the drawing. This frame carries suitable bear
ings in which is mounted a rock shaft ¿l thatl is
caused to oscillate rapidly about its axis by any
suitable mechanism. Attached to the forward 25
end of the rock shaft is a depending member 6
which receives oscillating motion from the rock
shaft and transmits the motion to a tool carrier
8 which is pivotally connected to it.
Mounted
on the tool carrier is an indenting wheel Ill and 30
an edge setting tool I2 which are adapted to per
form f1nishing operations on the edges of soles
of shoes. For details of the tool carrier 8 and the
tools carried by this carrier, reference may be
had to the disclosure of the Flynt patent referred 35
to above.
A stick i5 of solid finishing material is carried
in a holder comprising a flanged support I3 at
tached to the head of the machine adjacent to the
tool carrier. The support I3 has a head I4 pro- 40
vided with a central opening therein which eX
tends to a point adjacent to the knurling wheel
and the edge setting tool. While the flanged
support I3 is shown as being integral with the
head I4, it can obviously be made in several com- 45
ponent parts without departing from my inven
tion. The stick I5, which may consist of wax,
or a combination of wax and any color which it
is desirable to use, is slidably mounted in the cen
tral opening of the support I3 and is normally 50
urged outwardly in the direction of the finishing
tools by a spring I'B which is maintained in the
opening by a screw plug I'I threaded into the end
of the head I4. While the machine is not in use
the stick of finishing material is held in inoper- 55

ative position by a detent I9, the lower or stick
engaging end of which is positioned in the path
of movement of the work piece and which thus
serves as a feeler by which the presence of the
work piece releases the stick of finishing material.
The detent I9 has a shank 29 which is slidably re
ceived in an apertured arm 22 projecting from
the head. The aperture in this arm is larger than
the shank for the purpose of permitting limited
transverse movement of the shank when it is
reciprocated. Surrounding the shank and nor~
mally biasing the detent downwardly into a stick
engaging position is a spring 2I which is retained
at one end by the arm 22 and at the other by
a collar 20 which is attached to the shank. Pivot
ally attached to the shank of the detent between
the arm 22 and the work-engaging portion of
the detent are two links 23, 24 which are also
lustrated in Fig. 3 the sole edge of the shoe upon
engagement with the work-engaging member 33
moves that member in an upward direction car
rying the stick-engaging portion of the detent
out of engagement with the stick, releasing the
same, and allowing the spring T6 to force the
stick against the edge of the sole.
Having thus described the invention, what is
claimed as new and desired to be secured by
10
Letters Patent of the United States is:
l. In a device for applying a solid finishing
medium to a work piece, means normally urging
the solid finishing medium into engagement with
the work, and a detent for preventing movement
of the ñnishing medium, said detent being ar
ranged to be displaced by the. presence of the
work, thereby releasing the finishing medium and
enabling the first-named means to force the fin
pivotally attached to lugs on the head I4. When
20 a shoe is presented to the machine, the edge of
the sole of the shoe adjacent the stick holder will
engage the lower end of the detent, forcing this
member upwardly. This upward movement will
result in a pivotal movement of the links 23, 24
forcing the stick-engaging portion of the detent
away from the head and out of engagement with
the stick and thus allowing the spring I6 to force
the stick against the edge of the shoe.
In carrying out this operation, it is customary
ishing medium into engagement with the work.
30 to feed the shoe to the left 0r in a counterclock
tive to the receiving means, said detent being 30
wise direction as viewed in Fig. 2. Thus, when
the work is presented to the device disclosed
herein, the stick of finishing material I5 will
be applied to the edge. of the work just prior
35 to its presentation to the edge setting tools I0,
I2, permitting the operator both to apply the
finishing material to the edge of the work and
to perform the indenting and edge setting opera
tions with the indenting wheel and edge setting
40 tool in one continuous, uninterrupted operation.
As will be apparent from an inspection of Figs.
2 and 3, there is a very small gap between the
wax stick I5 and the finishing tools I0, I2. This
arrangement together with the adjustability of
the tools and the stick enables these members to
engage closely adjacent portions of the work and
facilitates the finishing of the more difficult por
tions of the edge,- such as sharp corners, and
around the toes.
In the construction disclosed in Fig. 3, the

of a work-engaging feeler 33 and guides the
movement of this feeler toward and away from
the work. The feeler-33 is normally biased in
a downwardly direction by a spring 35 which
surrounds the shank of the feeler 33 and is
located within the chamber, one end of this
spring abutting a plug 36 threaded into the
mouth of the chamber and the other end en,
