mechanism thus to move the retarders, the
sides of shoes. '
The machine herein shown, similarly to that
shown in the last-mentioned Letters Patent, is
provided with wipers, more broadly de?nable as
overlaying members, which are moved widthwise
of the shoe at the sides of the forepart to wipe
the margin of the upper inwardly over the insole,
and with retarders which are moved outwardly
over the insole toward the overlaying members
for clamping the margin of ‘the, upper against
these members to control it in the lasting ‘opera- '
tion._ .Early in the lasting operation-the re
tarders are moved reverseiy in inward directions
over the insole by the inward movements of the
overlaying members, after which they are moved
heightwise of the shoe and outwardly over the
overlaying members to release the margin of the
upper.
Included also in the machine is a shoe
rest which is moved heightwise of the shoe into
position to support the shoe at the top ‘of the
forepart during the operation of the overlaying
members and the. reta'rders on the upper, '
For purposes of this invention the construc
25 springs being yieldable to permit the retarders
thereafter to be moved inwardly over the insole
by the overlaying members. The retarders are
directly supported on arms which extend out
wardly therefrom widthwise of the shoe, these
arms being pivotally mounted on the above?
mentioned arms for movements heightwise of the
shoe to permit the release of the margin of the
upper by the retarders in the manner above de
scribed.
‘Ifhe above and other features oi‘ the invention,
including novel means for adjusting the retarders
and various novel details of construction and
combinations of parts, will now be more particu
larly described with reference to the accompany
ing drawings and thereafter pointed out in the
