head 8 to permit the passage of a pin Il extending I
laterally from the plunger. The lower end of the
plunger I5 is provided with a reduced extension I8
to which is detachably secured a shoe supporting
element I9. -The upper portion of the shoe sup
porting element I9 is provided with a- socket 20
to receive theextension I8 of the plunger and com
municating with said socket is a slot ZI defining
spaced ears 22 through which extends a bolt or
similar fastening device 23, by means of which
the shoe supporting element may be detachably
secured to the extension of the plunger. The
intermediate portion of the shoe supporting ele
ment I9 is preferably curved laterally While the
free end thereof carries a toe plate 24 adapted
to fit within a shoe, indicated at S.
The lower 50
end of the shoe supporting element is formed
with a slot 25 adapted to» receive a bolt vor other
suitable fastening device 26 so as to permit the
attachment of toe plates of different sizes and
shapes according .to thekind of `repair work to be 55

performed. Disposed beneath the plunger I5 is a
combined support and heating unit 21, said sup
upper end open and normally closed by a remov
able top or cover plate 29. The cover plate 29 is
provided with a circumferential retaining ñange
lamp, I make the support o-r anvil 4I shorter
and place in the bottom thereof a resistance coil
42 of any suitable construction. It is preferred,
however, to use an electric light bulb as the
heating unit as by so doing the electric bulb
may be readily removed and replaced by a new
bulb whenever necessary by simply detaching
30 which receives and holds a pad 3I formed of
the cover plate 29 and unscrewing the bulb from
rubber or other yieldable material. Disposed
within the tubular body 28 is a heating unit pref
the socket 33, as will be readily understood.
From the foregoing description, it is thought 10
that the construction and operation of the device
will be readily understood by those skilled in the
art and further description thereof is deemed
port comprising a tubular body 28 preferably
formed integral with the base 5 and having its
erably in the form of an electric bulb 32, the lower
end of which is detachably fitted in a standard
socket 33 connected in a lighting circuit 33’ in
cluding a switch 33”, as shown, and the purpose
of the heating unit is to hasten the drying action
of the cement when applying a patch to the sole of
a shoe.
Pivotally mounted at 34 on one side of the
guide block I3 is an operating lever 35, the piv
20 oted end of which is formed with an angular
extension» 36 to which is pivotally connected, at
31, one end of a connecting link 38, the opposite
end of which is pivotally connected, at 39, to
the adjacent portion of the plunger I5. A suit
25 able stop or rest 4€! is secured to one side of the
guide block I3 and on which the adjacent por
tion of the operating lever rests when the plunger
is in lowered position.
In operation, the toe or other portion of the
shoe S to be repaired is first skived or beveled
in the usual manner to receive the patch P,
after which said patch is coated with cement
or other suitable adhesive and applied to the
treated portion of the shoe sole. Assuming the
35 parts to be in the position shown in Figure 4 of
30
the drawings, the shoe with the patch in position
thereon is placed on the supporting element I9
and the lever 35 swung upwardly and laterally,
thereby bringing the supporting element I9 with
40 the shoe in position thereon directly above and
over the support or anvil 21. With the parts in
this position, the pin Il will aline with the slots
IIJ and I6 and, by pressing downwardly on the
lever 35 until it engages the stop 4D, the link 38
45 will force the plunger downwardly so as to cause
the toe plate 24 to press the patch against the
rubber pad of the anvil and in which position
it will be held until the heating unit 32 thor
oughly dries the cement. The rubber pad 3i
50
equalizes the pressure on the pad so as to cause
the patch to conform to any irregularities in the
surface of the shoe and thus produce a neat job.
It will here be noted that, when the lever 35 is
unnecessary.
'
' Having thus described the invention, what is 15
claimed as new is:
1. A machine of the class described comprising
a standard, a stationary slotted head carried by
the standard, a slotted guide block pivotally
mounted on the head, a plunger movable verti
20
cally within the guide block, a shoe supporting
element carried by thel plunger, a support dis
posed beneath the shoe supporting element, a
pin carried by the plunger and extending
through the slots in the guide block and head 25
respectively, and a lever operatively connected
with the plunger for pressing the supporting ele
ment and a shoe carried thereby against the
support to cement a patch'on said shoe.
2. A machine of the class described compris
ing a standard, a stationary head carried by
the standard and provided with a substantially
L-shaped slot, a guide block pivotally mounted
on the head and having a slot adapted to register
with a portion of the L-shaped slot, a plunger
mounted for vertical movement in the guide
block, a shoe supporting element carried by the
plunger, a support disposed beneath the shoe
supporting element, a heating unit housed with
in the support, means for pressing the shoe sup
porting element and a shoe thereon against the
support to cement a patch on said shoe, and
means for moving the suppo-rting element lat
erally to permit removal of a shoe therefrom.
3. A machine of the class described compris
ing a standard having an overhanging arm, a
stationary head carried by the arm and provided

vating the plunger and shoe supporting element
60 and this elevation of the plunger is continued
until the end of the pin I'I reaches the upper
end of the slot Ill when a further pressure on
the lever will cause the pin El to ride in the
lateral slot II of the head 3, thereby swinging
65 the guide block I3 and its associated parts lat
erally until swinging movement of the block is
arrested by engagement of the pin il’ with the
end wall of the slot I I. This swinging movement
of the guide block causes the shoe supporting
70 element I9 to assume the position shown in Fig
ure 4 of the drawings and in which position the
shoe may be readily removed from the toe plate.
