SHOE SOLE LAYING AND-_LASTING MACHINE
Meyer Siegel, Chicago, Ill., assignorAto Monarch
Shoe Company, Chicago, Ill., a. corporation of
Illinois
Application January 21, 1937, Serial No. 121,522
6 Claims.
The invention relates to improvements in shoe
sole laying and lasting machines and has for its
primary object the provision of an improved ma
chine or appliance of the character indicated
5 which is capable of economical production and
highly eiiicient in use.
Another object of the invention is the pro
vision of a construction of the character indi
cated so constructed and arranged as to facili
10 tate the proper shaping of a shoe and fitting of
the sole thereto.
v
Other objects will appear hereinafter.
The invention consists in the combinations
and arrangements of parts hereinafter described
and claimed.
'
The invention will be best understood by refer
ence to the accompanying drawings forming a
part of this specification and in which
Fig. 1 is a top plan View of the clamping ar
20 rangement employed in the device;
Fig. 2 a side View of the complete device on a
reduced scale;
Fig. 3 a partial section taken substantially on
line 3_3 of Fig. l; and
Fig. 4 a section taken substantially on line 4_4
25
of Fig. 1.
The embodiment of the invention illustrated
in the drawings comprises a suitable supporting
frame li; generally in the form of a. table. A
30 vertical last spindle II is arranged as shown
at the topV oi said table adjacent the front end
thereof. The shoe last of usual construction
and carrying a pre-welt shoe I2 is provided with
the usual socket to receive the upper end of
the spindle I i as will be readily understood.
Two laterally swinging plates or “wipers” I3
are arranged as shown on opposite sides of the
shoe and last, each clamping plate being pro
vided with curved beveled edges I4 nicely shaped
40 as best shown in Fig. 1 to the contour of the
corresponding sides of the rear portion of the
pre-welt shoe on the last. At the inner ends
the clamping plates I3 are reinforced at top and
bottom by reinforcing plates l5 and carry trun
45 nions I3 fitting into sockets in the tops of sup
porting posts Il and whereby the clamping plates
.I3 are pivoted to swing toward and away from
the last in planes just below the welt of the pre
50‘?, welt shoe on the last. The plates I3 pass free-'
ly over` the tops of the posts I8 and are provided
with stop blocks i8’ which limit their inward
swing at the proper positions. At their forward
ends the clamping plates I3 are provided with
55 handle members I9 arranged to be secured ÉQ
(Cl. 12-12)
gether in their innermost portions by a latch
member 20 as best shown in Fig. v1.
A third clamping member 2l is arranged as
shown to slide in guide grooves 23 formed in
the sides of the supporting frame and also to
enter guide grooves 23 formed as best shown
in Fig. 4 between the inner edges of the rein
forcing plates which are extended for this pur~
pose, said third clamping member thus being
caused to operate in the same plane as the '
clamping plates i 3. The third clamping mem
ber 2I has its inner edge 24 beveled and shaped
to the contour of the toe portion of the pre
welt shoe on the last, as will be readily Aunder
stood. The clamping plate 2I is normally held
in retracted position by means of a tension spring
25 and is connected as shown with the ends of
a pair of operating wires 26 attached to posts El
on the underside thereof. Operating wires 25
lead thence forwardly and downwardly around
the guide member 28 where they are connected
with the upper end of a belt or strap 29 in turn
connected with the foot lever 3D for operating
the same.
In use and in operation a pre-welt shoe com
prising the usual upper, insole and welt are se
cured to the last by temporary nails in the usual
Way and said last is then placed on the spindle
II and nicely adjusted thereon until the plane
of the clamping plates 2| and I 3 is arranged to .
pass just under the Welt of the shoe. The edges
of the plates I3 are then fitted around the shoe
just under the welt, and tightened and secured
in place about the rear portion of the shoe to
shape and hold the corresponding portions thereu
of on the last, as will be readily understood.
Then the foot lever 3B is operated to draw the
clamping member 2| into position to similarly
clamp about the shoe to shape and hold the toe
portion thereof in place on the last. As will be 40
noted, the clamping plates I3 are pivoted to swing
on the trunnions I5 which are located opposite
the toe portions of the last so that when clamp»
ing plates I3 are swung inwardly they first en
gage and position the sides of the upper before 45
the heel portions are effectively engaged thus
facilitating the stretching and shaping of the
upper to the last. Then the nails securing the
insole in place are withdrawn, adhesive is apu
plied to the insole and welt and the outer shoe 50
sole applied by heavy pressure and pounding to
be accurately and nicely secured in place. When
this has been done the shoe is in condition for
removal and sewing and trimming of the insole.
By this arrangement the shoe soles may be 55

glued in the same machine or appliance in which
the lasting is done; the clamping plates are a
a spring normally holding said third clamping
part of the lasting and sole laying mechanism;
the toe portion will be definitely and positively
and uniformly shaped; and heavy pressure and
pounding is permissible for the purpose of build
ing the shoe properly. The specific form and
arrangementl of parts is a simple and effective
forcing said third clamping member toward said
one for the purpose.
