gripper jaw in its forward position and away from
the reciprocating rear jaw, thus further facili
tating the insertion of the lasting margin of the
stock between the jaws.
The presser-feed member` of the illustrated nia
chine, as above mentioned, acts as a presser, or
hammer, to press, or pound, the overlasted mar
gin of the stock into adhering relation to the bot
toni of the shoe, and also as a feed-foot to move
the shoe bodily in a feeding direction. To facil
itate this feeding action this presser-feed-foot is,
in accordance with another feature of the inven
tion, constructed and arranged to move the shoe
downwardly and away from the bottom rest, thus
avoiding any tendency for the adhesively coated
shoe bottom to stick to the bottom rest or to drag
thereon. This presser-feed-foot descends sub
stantially vertically onto the overlasted margin
close to the point of action of the grip-per, and its

the presser-feed-foot; and an edge gage roll 2Q
for positioning the shoe laterally. These instru
mentalities are all mounted on, and operated by
mechanism contained within, a hollow head con
struction 22 comprising a lower portion 24 and a
removable top part 25 secured thereto by means
of cap screws 28, 28.
The rear gripper jaw l!) is attached, by means
of a clamping bolt 39, to the forward end of a
carrier 32 which is supported by two rocker arms
34, 36 journaled respectively on fixed cross shafts
38 and 4€] that extend across the lower portion
24 of the head 22. This carrier is pivotally se
15 cured to these rocker arms by means of studs
42, 44 and is movable forwardly and rearwardly of
the machine by means of a third rocker arm 46
that extends upwardly from a hub member 48
common to it and to the >rocker arm S6. The
the stock between the successive points of action
of the presser-feed-foot is nicely folded into small
and unobjectionable plaits, a feature of especial
rocker arms 34 and 36, together with that part
of the carrier 32 which extends between said arms,
constitute a parallel motion linkage so that the
carrier always remains horizontal during its for
importance where the lasting operation proceeds

For oscillating the rocker arm 46, to impart
the aforementioned movements to the carrier 32,
there is provided an eccentric 50 formed inte
grally with a main drive shaft 52V that extends
across the lower portion 24 of the head and
The effectiveness of the presser-feet-foot to effect
adherence of the stock, and to feed the shoe,
and that of the feed-retainer to prevent retro

work. The presser-feed-foot I6 is preferably so
which is connected by means of a link 2I4 to an
arm 2I6 which extends downwardly from a hub
arranged that in moving downwardly against the
shoe it tends, momentarily, to push the shoe
slightly away from the bottom rest I4, or at least
-appreciably to reduce the pressure of the shoe
bottom against the bottom rest, Vthus reducing
any tendency of the bottom rest to stick to the
bottom of the shoe, -see Figs. 3, 4, 5 and 6. The
angle crank 254 operates in a block 253that is
embraced by an elongated yoke member 2,82, see
Fig, la, which is secured to the shaft 246 by
2I8 which, like hub |94, is freely rotatable upon
the shaft |54. This arm has at its lower end
an oifset boss 220 which, when the treadle is re
leased, bears against a collar 222 on the rod |32
thus to hold the front gripper jaw I2 in its for
ward position. Accordingly, until the treadle is
depressed and the bottom rest and lasting shield
I4 moved into operative position, the rear gripper
jaw I 0 merely reciprocates idly without engaging
the front gripper `j-aw or exerting any pulling
means of a set screw 284, see Fig, 2. The hub
member 265 is held on the shaft 268 by means of
an upstanding piece of flat stock 286 which is
mounted on a reduced end of the shaft 48 and held
against a >boss 288 on the web portion |22 by
action on the stock. As will be seen from Fig. 7,
when the outer jaw is thus held in its outermost
position by the boss 220 the rods |02 and |03 are
separated a small amount.

outer end of a lever 242 which is pivotally mount
a shaft 298 mounted in the head portion 24. Also
extending from the hub 236 are two other arms
380 and 302, the former of which extends up
wardly to receive a tension spring 304, stretched
betweenit and an anchor pin 306 carried by the
upper Vhead portion 26, see Fig. 1,_while the lat
40 ter arm extends downwardly and rearwardly and
the presser-feed-foot I6, and lifting of the stock
by the next succeeding pulling action of the grip
per, by means of the presser-feed-member, or 30 per is prevented, by the feed-retaining member
i8.' The member I8 is secured by means of a
presser-feed-foot, I6, which thereafter, and
bolt 202 to the outer end of an arm 284 which is
while in engagement with the stock, is moved
formed integrally with a hub 296, journaled `on
laterally to feed the shoe. This presser-feed-foot
ed by means of a stud 24| on an upwardly ex
tending arm 244 formed integrally with a shaft
246 that is journaled in an elongated bushing 248
mounted in a bore 25E! in the web portion |22.
The lever 242 is oscillated, in time relation to
the operation of the grippers, to move the presser-f
feed-foot I6 against the stock, by means of an
isY formed with a cam track 308, having an arcu
ate part 301 and an eccentric part 309, over
which travels a cam roller 3I0. The cam roller
3|0 isrjournaled on a stud SI2 mounted in an arm
eccentric 252, carried by the shaft 52,v and the
shaft 246 is oscillated, to move the presser-feed
foot back and forth in a direction extending 45 3|4 which extends radially from the hub mem
ber 266. IThe cam track 368 is so shaped that as
lengthwise of the shoe, by means of an angle
the hub 266 is oscillated, by the eccentric 252,

la..` To augment its pressing action and to in
ber I8 will be successively urged toward the shoe
sure against slippage on the stock, the presser
feed-foot I6 is formed as a narrow blade-like
bottom, by the spring 334, held in this position

Surrounding the eccentric 252 is a strap 256

extends downwardly from a hub member 266
journaled on a shaft 268 mounted in a side wall
centric part 309 of cam surface 308. These move
ments of the feed-retaining member are so timed

linear feeding increment of approximately one
eighth of an inch is obtained and this affords sub

Accordingly, an average size shoe can be lasted
all around its entire periphery in a matter of
only a few seconds. While the herein illustrated
machine has been shown as operating on the last
