The next step of the process is to prepare a.

thereof, and that the upper edge of the stidening

into the fold vertex. By this procedure an at

stances it is not necessary so to cement the stiff

the heel pocket upon the last has the e?ect of

it with its interleaved stiffening blank, the last

subsequently the molded heel pocket may be in-‘
corporated into the shoe. Such procedure is par
ticularly useful in the manufacture of slippers,
whereas it would not apply to the manufacture of
,women’s pumps or oxfords.

‘
The invention has been discussed in its appli
cation to the manufacture of slippers for pur
poses of illustration only. It may be usefully ap
plied in the manufacture of women’s shoes in
and softening liquid applied to the stiffening
general, both in sandals and in shoes where a
blank or, if a thermoplastic material is used, the
stiifening blank is heated to a softened condition.
Whatever softening step may be employed, the
assembled heel pocket is next positioned upon the
heel end of the last I‘ and secured symmetrically
thereon by means of a single tack I 5, driven into
the heel end of the last. The forepart of the
upper, together with the shank piece'20, has al
ready been applied to the last and the margin of
the heel pocket extends upwardly about the rear

end of the last and shank piece.
'
The next step in the manufacture of the shoe
consists in drawing the forward ends of the heel
pocket inwardly by hand over the last bottom
and securing them in place by tacks H. In the
same 'way the rear end of the upstanding margin
is pulled inwardly and secured by a single tack
It. It will be understood that the material of
the stiffener is soft and pliable during these steps
and o?fers no resistance to, the overworking of the
margin of the pocket.
'
The step of drying and transforming the stiff
ening blank from its mulled, pliable and adhesive
condition to the stiff resilient condition required
in the ?nished shoe may be carried out at room
temperature or with the assistance of arti?cial
heat. The latter is usually preferable'both from
the standpoint of economy of time and because a
higher rate of drying usually imparts a greater
degree of stiffness to the stiffening material.
Having thus described my invention, what I
claim as new and desire to secure by Letters Pat
ent of the United States is:
1. A process of shoemaking which includes the ‘
steps of preparing, independently of the shoe,
2. lined heel pocket having a rolled upper vedge
with the line of juncture between the lining and
outer portion located entirely within the heel
pocket, inserting a stiffening piece which extends '
upwardly above said line of juncture in the heel '
pocket, lasting the heel pocket with the stiffener
Having prepared the shoe as indicated in Fig. 5,
it is presented to a heel seat lasting machine,
the wipers of which are represented in Fig. 5.
When the shoe has been properly located in the '
heel band of this machine the wipers are advanced
simultaneously, the entire upstanding margin of
the heel pocket is wiped into place and while so
held imder pressure the heel seat lasting tacks l9
are simultaneously driven, thus conforming the
heel pocket accurately and tightly to the, heel
end of the last and in this process molding the
stiffening material into the desired shape. In
the step of subjecting the miperposed margin of
the outer and liningportions to pressure with
the mulled stiffening blank between them the
margins of all three plies are cemented or fused
together in a single inturned ?ange. The heel
piece therein to form an inturned heel seat ?ange,
and then drying to stiffen the heel pocket in the
shape of the last.

2. A process of shoemaking which includes the
steps of preparing, independently of the shoe,
a lined heel pocket having its upper and side
edges shaped in a continuous curved contour with
a rolled edge formed in the outer portion, locat 40
ing a mulled stiffening piece in the heel pocket
with its edge in substantial contact with the
vertex of the rolled edge and above the line of
juncture between the lining and outer portions,
working the free edges of the plies of the heel
pocket over the last bottom, and drying to form
a stiff integral ?ange of the fused material.
3. A molded heel pocket for a slipper, compris
