for covering heels.
In covering wood heels of the Louis type it is
,r, customary adhesively to secure a single piece of
cover to the heel, the cover is progressively forced
against the heel by a tensioned, relatively hard 5
sheet material commonly known as a cover to the
convex surface of the pad.

then to secure the forward, the top and the bot—
tom projecting margins of the cover upon the
face of the pad applies the cover to the heel, it
is margins of the breast, the attaching and the top
lift receiving faces respectively of the heel. After
the partially covered heel has been attached to
the shoe, the breast of the same is covered by a
flap which is split from the heel end of the sole
13 of the shoe and is adhesively secured to the heel
breast.
Heel covering machines of various types have
been proposed. It is an object of this invention
to provide an improved machine for applying
As the convex sur
moves along the same in the form of a traveling
wave and stretches the cover as it applies the
same to the heel, thereby insuring that the cover
shall be free from wrinkles. The unlaid portion
of the cover is slightly tensioned before it is ap
plied to the heel through the provision of clamps
which force the lateral margins of the cover
against the pad throughout the covering opera 15
tion and which are moved under pressure of the
pad.
The output of the machine is increased by
ious shapes quicker and more effectively than
has heretofore been possible. In accordance with
mounting a plurality of units, each of which com
prises one of the cover-applying pads and a pair
of pad-supporting plates, upon a turret. Suit
able mechanism is also provided for holding the
one feature of the present invention the illus
pad in wrapped relation with the heel while the
“0 covers to the rear and side faces of heels of var
trated machine comprises a holder for a heel, a
3 resilient pad for supporting a ‘cover, and means
comprising the pad constructed and arranged to
apply the cover to the rear face of the heel pro
gr ssively from one end of the heel to the other,
and cooperating means for then applying the
cover progressively to the sides of the heel. In
the illustrated construction the pad is supported
by a pair of plates which are spaced by an open—
ing, the central part of the pad having a depend—_
ing portion which ?ts within the opening. The
35 heel holder is mounted for movement about an
axis to swing the heel against the cover and into
the pad, the cover being applied to the rear face
of the heel progressively from the attaching end
to the tread end of the heel as the heel with the
it) pad Wrapped about it is moved into the opening
between the pad-supporting plates. The plates
are mounted for movement about parallel axes
respectively which are disposed at approximately
right angles to the axis of rotation of the heel
:j. holder.
After the cover has been applied to the
rear face of the heel, the pad-supporting plates
turret is being indexed from an operating station
to a discharge station thereby permitting the 25
cover-attaching cement to dry while the cover is
forced against the heel. The turret is indexed in
timed relation with the cover-applying mecha
nism of the machine, the operator, after placing
the heel in the holder, having only to trip a 30
treadle to set the machine in operation for the
purpose of covering the heel and indexing the
machine.
The above machine covers heels of
various shapes quickly and effectively and mate
rially reduces the cost of the heel-covering oper
ation.

’ These and other features of the invention, in
cluding certain details of construction and com
binations of parts, will be described as embodied
in an illustrative machine and pointed out in the
appended claims.

The illustrated machine is described with ref
erence to applying a celluloid cover to the rear
and side faces of a Louis heel 22. During the

In order to' insure that the cover-attaching
cement shall dry before pressure of the pad
is provided with six cover-wrapping units which
are successively moved to and past the covering
station 50, the turret being intermittently actu
ated by suitable indexing mechanism which is
operated in timed relation with the heel-cover
ing mechanism and will be described later.
Power to operate the machine is supplied
through a drive shaft 52 (Fig. l). A worm 54
which is keyed to the drive shaft 52 is in meshing
engagement with a gear 56 secured to a cam
shaft 58 rotatably mounted in the frame of the

Preparatory to applying the celluloid cover tov 48 and the cam plate 12 are rotatably mounted
the heel, the cover is softened by inserting the upon a cylindrical extension 18 (Fig. 4) of a bear
same in a bath of a suitable solvent, the edge ing 80 which supports the turret and the cam
portions of the heel being previously coated with plate 12 and which is secured by screws 82 to the
cement.
Before a leather or fabric cover is ap
main frame.
40 plied to the heel it is customary to coat the out
side face of the heel as well as the inside face
of the cover with cement or other suitable adhe
sive.
The heel to be covered is carried by a heel
holder 38 which is mounted for swinging move
ment about a bearing 32 supported by a bracket
34 which is secured to the main frame 36 of the
machine by screws 35 through mechanism which
will later be described. The cover to be applied
50 to the heel is placed upon a pad 38 mounted upon
supports or plates 40 which are spaced to form
an opening 42 (Fig. 3). The pad 38 comprises
a central depending portion 44 which is posi
tioned within the opening 42 between the sup
ports 40. The heel 22 which is securely gripped
by the holder 30 is forced against the cover 28
and into the central portion of the pad 38 thereby
applying the cover to the rear face of the heel
progressively from the attaching face of the heel
(Figs. 6 and 7) to the top-lift receiving or tread
face of the heel.
'
After the cover has been applied to the rear
face of the heel the supports 40, which are pro
vided with trunnions 46 swiveled upon a turret
48, are swung upwardly to wrap the lateral mar
'
The bracket 34 upon which the heel holder 30 40
and the operating mechanism therefor is mount
ed is secured to the top of the cylindrical ex
tension 18 by screws 35 as above stated. In
order to support the front end of the turret 48
against downward displacement during the heel as. Cl
covering operation, the bottom face of the turret
is continuously in engagement with a brace 86
(Fig. 4) secured by screws 88 to a circular plate
90 which is fastened to the machine frame by
screws 92.
50
The heel holder 38 comprises a rear abutment
94 provided with a plurality of sharp teeth 96
for engaging the central portion of the attaching
face of the heel, and a front abutment 98 con
structed and arranged to engage the tread and
the breast faces of the heel. The front abutment
88 is adjustably secured through a slot-and-screw
connection 5 80 with relation to an abutment car
rier I02 mounted upon a bearing rod I04. The
abutment carrier I02 may be adjustably se
cured through the provision of a slot—and-screw
connection I06 to an arm I08 which is pivotally
mounted upon the bearing rod I04. The arm
I88 is swung in a clockwise direction, as viewed
in Fig. 1, by a roll H0 which is mounted upon a
rocker arm H2, during a portion of the cycle of
gins of the pad 38 about the sides of the heel,
thereby applying the cover 28 progressively to operation of the machine, thereby swinging the
opposite sides of the heel. The supports 48 may front abutment 98 away from the rear abutment
94, the arm I08 at all times being held in con
be swung upwardly to the vertical positions illus
trated in Figs. 4 and 12 in order to insure that tact with the roll H0 through the provision of '
the pad 38 shall apply the top, the front, and the \a spring H4. The lower part of the spring H4
bottom projecting margins 24, 26 and 28 of the ‘is positioned within a cavity formed in a lever
H6 and the upper part of the spring ?ts within
cover to the attaching, the breast, and the top
lift receiving faces, respectively, of the heel. a cavity of the arm I08. The effective strength
75 After the cover 20 has been applied to the heel of the spring H4 may be varied by turning a 75
2,119,840
screw II8 which is in threaded engagement with
the arm Hi8 and engages a washer I28 which is
inserted in the cavity and engages the upper end
of the spring. A grip plate I22 is secured to the
lever I I6 by screws I24 and is positioned in front
of the rear abutment 94.
When the machine is started by stepping upon
a treadle I25 which trips a one-revolution clutch
E26, the roll IIIl of the rocker arm H2 is raised
thereby permitting the spring I I4 to cause the
front abutment 98 to swing toward'the rear abut
ment 94, the attaching face of the heel being
forced with considerable pressure against the
eeth 96 of the rear abutment as the grip plate I22
15 is flexed. In order to position the heel in the
holder 36 the operator forces the attaching face
of the heel against the ?exible grip plate I22 and
moves the tread and breast faces of the heel into
engagement with the abutment 94. The heel is
20 centralized in the holder by sight and has its lip
forced into engagement with a gage I23 which is
adjustably secured to the grip plate I22. When
the operator releases his hold on the heel the grip
plate
forces the heel against the front abut
25 ment 93 with suflicient pressure to retain the heel
in position until the abutment 98 forces the at
taching face of the heel against the teeth 96 of
the rear abutment 94. Heels of different pitches
may be accommodated in the machine by adjust
30 ing the abutment $8 with relation to the abut
ment carrier £52, and heels of different heights
may be accommodated in the machine by adjust
ing the abutment carrier I02 with relation to
35
the arm I08.
The rocker arm I I2 is mounted upon a bearing
!.28 secured to the bracket 34 and is pivotally
connected to a rod I30 the lower end of which is
pivotally connected to a bell-crank lever I32
mounted upon a bearing I34 supported by the
machine frame. The lower end of the bell-crank
lever I32 carries a follower roll I 36 which en
sages Within a groove I40 of a cam I42 keyed to
the shaft 58.
34 continues its downward swinging movement.
It will be noted that throughout the covering op
eration the lateral portions of the ‘cover are
forced against the pad 38 by a pair of clamps
H2. The clamps I52 are yieldingly movable
under pressure of the pad and will later be de
scribed in detail.
The pad may be made entirely of rubber as will
later be described. It has been found preferable.
however, to provide the pad with the pocket I48 10
which is ?lled with the round particles of sand
M9 in order to insure that when full Louis heels
are being covered, convex cover-applying sur
faces of sharp curvatures shall be formed on the
pad. The sand E49 offers a substantial amount 15
of resistance to displacement and provides a ?rm
backing for the cover~supporting surface of the
pad 3&3. As the heel in the holder 30 swings down
wardly against the cover and into the pad 38
the convex portion I50 of the pad moves toward 20
the tread end of the heel and rolls the cover
against the rear face of the heel as it travels
along the same. The cover may therefore be
described as being applied to the heel by the trav
eling wave action of the pad 38. The pad 38 is
freely movable under pressure with relation to
the supports 4i), thereby permitting the pad to
creep relatively to the heel as it is compressed
between the heel and the supports. The pad 38
therefore stretches the cover as it applies the 80
same to the heel. The bearing 32 about which
the holder 30 is rotated is so arranged that the
heel being covered has a rearward component of
movement while it forces the heel against the
cover and into the pad.
After the cover has been applied to the rear face
of the heel, the pad supports 40 are swung upon
trunnions 46 to cause the pad to wrap the
cover 24 about the sides of the heel. The holder
3!! in the meanwhile continues to force the heel 40
into the central portion of’ the pad 38 and into
the opening 42.
As above stated, the supports
40 are usually swung into the upright positions
The depending portion 44 of each of the pads 38
45 engages a base pad I44 (Figs. 10 and 12) of soft
rubber, which is mounted upon the turret 48 be
neath the opening 42 formed between the plates
45 and ?lls a recess I46 formed in the upper sur
face of the turret 48. In order to improve the
50 effective operation of the pad 38 when operating
upon heels having sharp curvatures, the pad is
provided with a pocket I48 which is ?lled with
sand I49 consisting of round particles which shift
readily under pressure during the heel-covering
55 operation. The sand is inserted in the pocket I48
through a tube I5I (Fig. 10) which is in threaded
relation with a cap I53.
As the heel holder 38 is swung toward the pad,
the upper end of the rear face of the heel en
60 gages the cover positioned upon the pad (Fig. 6)
and upon continued movement (Fig. 7) of the
holder 38, the rear face of the heel is swung
against the cover and into the pad thereby caus
ing the cover to be applied to the rear face of the
65 heel progressively from the attaching face to
the top-lift receiving face of the heel.
As the
rear face of the heel is swung against the cover
and into the pad 38 the portion I59 (Fig. '7) of
the pad which is located immediately in ad~
70 vance of the portion of the pad applying the
cover to the heel, assumes a convex shape, as
viewed from the side of the heel.
3
The convex
portion 25% of the pad is tensioned and travels
progressively ahead of the portion of the cover
75 which is being applied to the heel as the holder
best illustrated in Fig. 12 in order to apply the
projecting margins 24, 26 and 28 of the cover to 45
the attaching, the breast, and the top-lift receiv
ing faces of the heel. The mechanism for op
erating the supports 40 will be described later.
The opening 42 formed between the spaced
supports 443 is enlarged at its rear end in order 50
to accommodate the wide upper portion of the
heel. As shown in Fig. 8, ‘when the machine is
idle the axes I54 about which the supports 40 are
swung are spaced from and positioned above cor
responding inner ends or end faces I56 of the 55
supports 46, the arrangement being such that as
the supports 44 swing to the vertical-positions,
the opposing end faces I56 of the respective sup
ports 49 move away from each other, thereby in
creasing the width of the opening 42 in order 60
to. insure that the resistance to downward move
ment of the heel shall not be excessive.
As the heel is forced into pad 38 and the sup
ports 44 are swung about the heel the sand I 49
located in the pocket I48 of the pad shifts under 65
pressure to form a convex portion or wave I58
(Fig. 8) which extends generally heightwise of
the heel and follows the curvature of the'heel.
As above stated, the sand provides a relatively
?rm backing for the work-engaging. portion of
the pad. The unlaid portion of the cover posi
tioned between the heel and the clamps I56 is
tensioned throughout the covering operation. As
above stated, the pad 38 is not secured to the
respective supports and is therefore free to creep 75
2,119,840
underpressure with relation to the supports as
the cover is applied to the heel. Although the
supports 88 are illustrated as being mounted for
swinging movement about ?xed pivots it will be
understood that in de?ning the supports as be
ing mounted for angular movement it is not in
tended that the axes about which the supports
are swung'shall necessarily be ?xed.
Each of the clamps I52 is pivotally mounted
ment with faces I94 (Fig. 12) of the supports.
10 upon a rod I88 which is secured by a screw I62
I90 carry rolls 206 (Figs. 2 and 4) which engage
within guideways 208 formed in the rear face of
a cam plate 2I0. The cam plate 2I8 is provided
with a pair of elongated slots 2I2 (Fig. 2) of suit
to a clamp carrier I64 mounted upon the bear
ing 32. The clamps I52 are normally retained
in their lowered positions upon the respective
rods I30 by springs I66 the rear end of each of
The arms I90 are pivotally secured to a slide I96
(Fig. 2), a rear portion of which is mounted for
vertical movement along a guideway I98 (Fig. 4)
formed in the circular cover 90. The slide I98
carries a rearwardly extending cam roll 200 con
structed and arranged to engage within a groove
202 of a cam 204 secured to the forward end of
the cam shaft 58. The lower ends of the arms
able size to receive screws 2 I4, respectively, which
been tripped to operate the machine the clamps
are in threaded engagement with the circular 15
cover plate 90. It will be noted that the upper
ends of the guideways 208 diverge from the plane
of swinging movement of the holder 30 in order
I52 (Fig. 5) are swung downwardly into engage
to cause the arms I80 to swing toward each other
ment with the respective lateral margins of the
cover supported by the pad 38, under the action
of a strong spring I68, the lower end of which
at the top of their strokes. With such an arrangement the supports 40 are moved suf?ciently
close to each other to insure that they shall ef
fectively apply covers to the lateral margins of
the attaching, the breast, and the top-lift receiv
ing faces, respectively, of the heel as above de
scribed.
In order to retain the supports 40 in their closed
positions (Figs. 11 and 12) while the turret 48
is being indexed to the discharge station I88 (Fig.
3), each of the supports 40 is provided with a
rearwardly extending lug 2I6 arranged to engage
a serrated lever 2I8 (Fig. 5) which is pivoted
15 which is secured to the rod I60 and the front end
of each of which engages an end of a notch I81
formed in the clamp.
After the clutch I26 has
is secured to a rear extension I'I0 of the carrier
I63 and the upper end of which is secured to the
~ bracket 34.
In order to insure that the clamps I52 shall
not‘ be engaged by the pad 38 wrapped about
the heel or by the closed supports 40 (Fig. 4)
during the indexing of the turret 48, the clamps
are positively moved to raised positions against
the pressure of the spring I68 by a connecting
rod I12. The upper end of the connecting rod
H2 is pivotally secured to the rearward exten
sion I'll] of the clamp carrier I64 and the lower
_ end of the connecting rod is pivotally secured to
a bell-crank lever I'I'4 which is held against an
open cam track I'IS by the spring I68. After the
turret 48 has been indexed the clamps I52 are
permitted to move downwardly under action of
40 the spring I68 until they are positioned just
above the margins of the open pad 38 (Fig. 1).
As the supports 40 and the lateral margins of
the pad 38 are swung upwardly the clamps I52
swing inwardly (Fig. 9) about the respective rods
I08 against the action of springs I68, and after
turning through approximately 90° are rotated
about the bearing 32 against the action of the
spring I88. After the cover has been applied to
the heel (Fig. 14) a high portion of the cam track
I78 moves into engagement with the bell-crank
lever I14 to raise the clamps I52 above the closed
supports 48 (Fig. 4).
The heel holder 30 is operated by a rod I'IB, the
upper end of which is pivotally secured to the
> ; rear end of the lever H8 and the lower end of
which is adjustably secured through the provi
upon a bracket 220 secured to the turret 48 and
is rigidly connected to an arm 222. The arm 222
carries a roll 224 which is constantly urged by a 35
spring 226 (Figs. 4 and '10) against a bar 228
which is supported by a projection of the bracket
220. The bar 228 is normally in contact with the
projection of the bracket 220 under action of a
spring 230 surrounding a rod 232 which is secured 40
to the bar 228 and carries a roll 234. As the sup
ports 40 are swung to their closed positions they
force the lugs 2I6 against the respective serrated
arms 2 I8 which swing upwardly against the ten
sion of the springs 226 (Fig. 4). The serrated
arms 2I8 thus prevent the supports 40 from open
ing under action of the pad 38 after the arms
I90 have been lowered. In order to permit the
supports 40 to open when the unit has been in
dexed to the discharge station I88 (Fig. 3) a cam
235 is secured to the frame of the machine. As’
each of the rolls 234 (Fig. 4) engages the cam
‘236 the rod 232 raises the bar 228 against the
action of the spring 230‘ and forces the arms 222
which are already held in raised positions up
wardly, thereby swinging the serrated levers 2I8
the unit of the turret has been indexed to a dis
upwardly out of engagement with the lugs 2I6
and permitting the supports 40 to drop to their
open positions. The covered heel is then removed
from the machine.
Although the machine has been described with
reference to the pad 38 having the pocket I48
which is ?lled with sand, it will be understood that
a pad 240 (Fig. 13) formed of a single piece of
rubber may be used. If’ desirable, the pad 240
may be provided with a pair of upstanding gages
I42 which are engaged by the cover and assist the
operator in positioning the same upon the pad.
Preparatory to covering the heel, the edge por
tions of which have been coated with cement,

I52 lead the holder 30 in order to insure that the
margins of the cover are forced against the pad
38 before the heel 22, carried by the holder 30,
forces the cover into the pad.
“After the heel 22 has been covered the front
= abutment 98 is swung away from the rear abut~
ment 90 and the holder is raised above the closed
supports 48 to permit the turret 48 to be indexed.
Suitable mechanism which will be described later
is provided for causing the: supports 40 to retain
~ _ the pad 38 in clamped relation with the heel until
The supports 48 are swung about their respec
tive axes I54 by a pair of arms I90 provided with
75 rolls I92, respectively, which move into engage
-
ously therewith moves the lip of the heel into
engagement with the gage I23 and also moves
the breast and tread faces of the heel into en 76

2,119,840
gagement with the abutment 98. After placing
the cover upon the pad 38 the operator steps
upon the treadle I25 thereby tripping a one
revolution clutch I26.
As the cam I62 rotates
the rod I30 is lowered to permit the abutment
98 to force the heel under action of the spring I it,
against the teeth 96 of the abutment 9d, the
clamps I52 in the meantime being lowered under
the action of the spring I68 to force the margin
10 of the cover against the pad 38. The holder is
then swung downwardly to force the heel against
the cover and into the pad thereby applying the
cover to the rear face of the heel progressively
from the attaching end to the tread end of the
15 heel. When the cover has been applied to the
rear face of the heel the arms I96 are raised
and at the top of their stroke are swung toward
each other to move the supports 49 to their closed
positions thereby applying the cover to the sides
20 of the heel as well as to the margins of the breast,
the tread, and the attaching faces of the heel.
After the heel has been covered theholder 36
and the clamps I52 are raised and the arms 199
are lowered to permit the machine to be indexed.
25 The supports 40 are held in their closed positions
when the arms I90 have been lowered, by the
serrated levers 2l8, which are in engagement
with the lugs 2l6 of the respective supports Mi.
When the machine has been indexed to the dis
30 charge station l88 the cam 236, through the
above-described mechanism, forces the serrated
levers 2 l8 away from the lugs 2 I 6 and permits the
supports 40 to be lowered under action of the
pad to their open positions. The covered heel
35 is then removed from the machine.
