"
100 is the base of the machine. 101 is a stand frame which may be of any suit-
able construction and material and whose top, 102 serves to support the head of the
machine. 103 is a counter-shaft fitted in bearings 104 on the stand frame. The
shaft 103 carries a balance-wheel, 105 and a belt-pulley 106. Upon the shaft is a
fixed collar, 107, which forms one member of a friction clutch. 108 is & cone
pulley turning loose upon the shaft, 103 and restrained from endwise movement on
the shaft. The hub, 109 of this pulley forms another member of the friction clutch,
the other member being formed by a friction wheel, 110, which is V-formed at the
periphery to fit the beveled ends of the collar, 107 and the hub 109. The con-
struction is such that when the wheel 110 is moved toward the shaft 103, motion is
The

wheel 110 has bearing in the forked end 111 of an arm, 112 hinged to the frame
at 113 so that by a slight swing of the arm on its pivot or hinge 113 the wheel may
be moved into or out of contact with the other members 107 and 109 of the clutch.
The central part of the arm 112 has ear or ears 114 to which is hinged one end of
a connecting rod 115 whose other end is hinged to the central part of an arm or
lever 116 fulcrumed to the frame at its lower end, 117 and carrying at its upper
end 118 an anti-friction wheel. 119 is a treadle-lever keyed to a fulcrum shaft 120
near the top of the stand frame and having at the lower end a forward extension or
foot 121 whose lower edge 122 is in the arc of a circle whose centre is at the
fulcrum point 120 of the lever 119. The construction is such that when the lower
end of the lever 119 is moved backward from its normal position that the edge 122,
bears on the anti-friction wheel at 118 and forces the lever 116 backward so that
the clutch wheel, 110 is pushed against the other members of the clutch and the
cone pulley 108 caused to rotate. The lever 119 may now be swung further back
without changing its bearing upon the anti-friction wheel at 118 so that the machine
will continue running in all positions of the lever 119 except its normal position
shown in Figures 82 and 84. The lever 119 is also used to regulate the power of
the spring by which the crimping pinchers are drawn upward, and the operation of
the lever for this purpose will now be described. 123 is a connecting rod, one end
of which is hinged to the lever 119 and the other end hinged to the vertical arm 124
of a bell-crank lever, whose horizontal arm 125 is forked at the end 126. Through
the fork extends from above the rod 127 of the lifting spring 128 whose upper end
is connected to the rear end of the lever 129 by which the crimping pinchers are
drawn up. 130 is a collar upon the rod 127 held in place by a set screw 131 and
having at top ribs 132 which occupy notches in the underside of the fork 126 the
construction being such that as the lever 119 is moved backward the forked end 126
133 is a ratchet-bar

immediately below the edge 122, and 134 is a pawl hinged to the treadle foot 121
and adapted to engage the ratchet bar 133 and hold the lever 119 from forward
movement. To engage the pawl with the ratchet the pawl is depressed by the foot
of the operator and when engaged with the ratchet is held in engagement by
friction. On a slight backward movement being given to the lever 119 the pawl is
thrown up by a spring 135 beneath it and then the lever may be swung forward by
the spring 128.
In order to check the rapid movement of the lever I connect with it a dash-pot,
which will be now described.
The horizontal arm 125 of the bell crank is hinged to the rod 136 of a piston 137 ;
the piston working in an open-bottomed cylinder 138 hinged at 139 to the stand
frame. The cylinder has at its upper end a small vent hole 140 that is screw-
142 is a screw
threaded, and a channel 141 is cut through the thread at one side.
fitting in the hole 140 and made flat at one side as seen at 143. The construction
is such that when the flat part 143 of the screw exactly coincides with the channel,
that the air passes freely through the channel and by turning the screw the channeĺ
may be partly or wholly closed.
141 is the foot of the treadle by which the crimping movements are governed and

page_text: also the position of the last. The treadle foot rocks on a pin 145 which also forms
the pivot of a treadle arm 146 to whose free end the treadle rod 147 is hinged.
The arm 146 has a vertical longitudinal slot 148 through which passes a
downward extension 149 at the rear part of the treadle foot and is held by a
screw bolt 150 that passes through the arm and through a slot 151 in the
extension 149.
The head of the machine has a base 152 which is secured to the top of the stand
frame and an upright frame 153. The frame 153 may be attached directly to the
top of the stand without the intervention of the base 152. The frame 153 is of any
suitable construction to give bearing to the moving parts; and may be made partly
or wholly integral with the base 152. 154 is a shaft carrying a cone pulley 155
connected by a belt 156 with the cone pulley 108 on shaft 103. The shaft 154 has
bearings at 157. 158 is a spur pinion upon the shaft 154. The spur pinion 158
engages a spur wheel 159 upon the cam shaft 160. The shaft 160 has bearings
at 161 in the fixed frame 153. The shaft 160 carries a balance wheel 162 which
is adapted to be used as a hand wheel in adjusting the mechanism to any desired
position when it is not running.
163 is a longitudinally sliding frame or carriage having faces, 164, bearing
against parts 165 of the fixed frame, and bearing strips 166 which are inserted over
the carriage, see Figs. 2, 4, 20 21 and 40.
167 are extensions from the rear part of the carriage which have inwardly
projecting studs 168 carrying anti-friction rollers 169 that work in the cam
channels 170 of the cams 171 and 171* upon the shaft 160. These cams rotate in
the direction indicated by the arrow, and cause the longitudinal reciprocation of the
carriage.
The pinchers with their rod or stem are shown in detail in Figs. 27 to 32
inclusive. 172 is the pincher rod or stem to which the jaws 173 and 174 are
pivoted at 175. The rod 172 carries a sleeve 176 which has endwise movement on
the rod. The sleeve has extensions 177 lying each side of the jaws and connected
by three cross-pins 178, 179 and 180 carrying anti-friction rollers. The construction
of the parts is such that when the sleeve 176 moves downward on the rod 172, the
pins 178 and 180 by pressure against the outer sides of the jaws press their points
together to hold the edge of the leather while the pinchers are raised to draw up
the leather on the last.
To release the leather, the sleeve is drawn upward on the rod when the points of
the jaws 173 and 174 are separated by the upward movement of the sleeve on the
rod, which relieves the jaws from the pressure of the pins 178 and 180 and the jaws
are opened by the pressure of the pin 179 against their inner sides. The jaws are
shown in their open and closed positions in Figs. 27 and 28 respectively. The
points of the jaws are serrated to give them a firm hold of the leather.
I will now describe the means for giving the described vertical movements to the
rod 172 and sleeve 176:
The rod has two fixed collars 181 between which is a loose ring 182 having at
opposite sides transversely projecting studs 183 which have bearing in blocks 184.
These blocks have bearing in slots 186 in the forked end 185 of the lever 129, the
blocks having slight end wise movement in the slots, as the rod has rectilinear
movement and the end of the lever moves in an arc of a circle. The lever 129 is
fulcrumed in the carriage at 187.
The upward movement of the forward end of the lever 129 and the pinchers, in
drawing up the leather, is caused by the spring 128 while the downward movement
of the pinchers is caused by the cam 171, the lever having a cam_stud 188 armed
with an anti-friction roller which plays in the cam-channel 189. In order to allow
the spring to act to draw up the pinchers there is a recess 190 at the side of the
channel 189 into which the cam stud enters, see Fig. 18. The jaws of the pinchers
are open when they descend, the edge 191 of the leather being between them and
immediately after reaching their lower position the sleeve 176 descends and closes
them upon the leather. The sleeve 176 carries a fixed collar 192 having a

page_text: circumferential channel containing a ring 193 with studs 194 working in blocks 195
that have endwise movement in slots 197 in the forked end 196 of the lever 198.
This lever is fulcrumed to the carriage at 199 and its rear end is connected to the
lever 129 by a spiral-spring 200. The spring acts to depress the sleeve 176 when-
ever the sleeve is not lifted by either its special cam 204 or by the pincher rod.
The collar 192 bears at bottom upon a shoulder 201 of the sleeve and is held at top
by a nut and washer 202, see Fig. 27.
The lever 198 has a cam stud 203 carrying an anti-friction' roller which bears
against the cam 204 of the cam-wheel 171". The cam has a part between the
salient points 205 and 206 which allows the ascent of the stud 203 under the
influence of the spring 200 to carry down the sleeve and close the jaws (as before
set forth). When the jaws close upon the leather the rod 172 is drawn up by
spring 128 and lifts the sleeve 176 with it until the jaws have reached their highest
point when the stud 188 reaches the end of the channel enlargement 190 and the
rod 172 is held rigid; at the same time the projecting part 206 of the cam 204
reaches the stud 203 and lifts the sleeve opening the jaws and releasing the
leather 191. After the jaws are opened the rod and sleeve again descend together
in the same relative position until the jaws reach their lowest point when the sleeve
again descends on the rod and closes the jaws, as before described.
As the pinchers are ascending the carriage is at rest, but as they reach their
upper position, and before they open, the carriage begins a forward movement so
that the leather 191 is not simply drawn upward but also drawn forward over the
last, while at the same time the folder 207 begins to move forward and folds the
edge of the leather down on the insole 208, the pinchers opening while the folder
is moving forward. At the same time the spring pusher feet are pressed against
the leather and insure its smooth folding against the side of the last. The jaws
open while the folder is moving forward and the folder continues its forward move-
ment and folds down the edge of the leather. The carriage continues to move forward
and the tack is driven through the leather and insole.
The sleeve 176 has bearing in the forward extension 209 of the carriage, and the
rod or spindle 172 has bearing in the sleeve and above the sleeve in the
extension 210 of the carriage. The top of the rod 172 carries a head 211 by which
the rod is turned (when required) for the crimping of the leather.
The folding and pressing devices are upon a single head 212 supported on a
rod 213 which has bearing in a longitudinal socket 214 in a downward extension 215
of the carriage. The rear end 216 of the socket is closed except for a hole of
smaller diameter than the socket through which passes a reduced part 217 of the
rod. This reduced part 217 is screw-threaded and carries a stop-nut 218 and a
lock-nut 219 the former of which limits the forward movement of the rod in the
socket. 220 is a spiral spring surrounding the part 217 within the socket and
whose rear end bears against the rear end 216 of the socket while the front end
bears against the shoulder 221 of the rod. The spring acts to push the head 212
forward. At the rear of the reduced part 217 is a still further reduced part 222
that passes through a post 223 fixed to the base 152 behind the post 223 the rod
is screw-threaded and carries a stop-nut 224 and a lock-nut 225, the former limiting
the forward movement of the head 212 relatively to the fixed frame, so that it does
not accompany the carriage in its extreme forward movement.
The folder 207 constitutes the front end of the horizontal arm of a bell-
crank 226 which is fulcrumed to the pusher-head at 227. The vertical arm 228
of the bell crank rests, at its front side, against a sliding block 229 bearing against
the rear end of a spiral spring 230 whose front end rests against an adjusting
screw 231 by which the power of the spring may be governed. 232 is a screw
whose front end rests against the rear side of the vertical arm 228 to limit the
descent of the folder. Thus the folder is pressed down on the fold 191 of leather
by the spring 230 and the amount of pressure regulated by the screw 231.
The head 212 has a number of holes 233 to receive fixed pins 234 which are
surrounded by spiral springs 235". The presser bars 235 are in a vertical series

page_text: The
and are made rectangular in transverse section so as to fit snugly together.
presser bars have sockets 236 to receive the front ends of the pins 234 and the
spiral springs surrounding the pins. The fore ends of the spiral springs rest against
the inner ends of the sockets 236 and their rear ends against the head 212. The
presser bars have side wings 237 which work in slots 238 of the removable side
plates 239 of the head. The bars 235 end in pads 240 which bear against the
leather and push it against the side of the last. In order to hold the bars in their
retracted position (which is sometimes required in examining or testing parts of
the machine) I provide a catch 241 which turns one-fourth around in bearings 242
and which has a number of teeth 243 adapted to enter the slots 238 and engage the
fore-ends of the wings. Ordinarily the catch 241 is in the position seen in Fig. 44
and does not interfere with the end wise movement of the bars. The lower part
of the head has a fixed extension 244 which is bored through at 245, the
bore extending through the body of the head and receiving the screws 231, 232,
the block 229 and the spring 230. The retracted position of the pusher bars
with the catch in holding position are shown in Figs. 45, 47. The means for
regulating the feed and for crimping the leather (191) at the toe of the shoe will
now be described.
a
The treadle 144 has an upper position at the toe as shown by dotted lines at 246
Fig. 82 a middle position shown in full lines at 247 in the same figure and a lower
position shown by dotted lines at 248 in the same figure. The crimping takes
place only when the treadle is in the lower position and this is done by turning the
pinchers while they hold the leather. The treadle rod 147 is connected at the upper
end to a crank arm 249" upon a rock shaft 249 having upon it a worm cam 250.
One end of this cam has a wrist pin 251 that occupies a slot 252 in the lower end of
a connecting rod 253 connected at the upper end to a lever 254 working on a
fulcrum 255 upon the fixed frame 153. The lever 254 is held in its normal and
horizontal position (scen in Fig. 3) by a spring 256 extending from its free end to
the fixed frame. To the other end of the lever 254 is pivoted a pin 257 that works
in a vertical socket 258. The top of the pin extends above the top of the frame.
259 is an arm pivoted to the frame 260 so as to swing in a horizontal plane and
drawn toward the head 211 of the pincher-rod by a spring 262 connected to the
arm and to a pin 261 on the fixed frame. This arm carries at the free end a
standing bevel-ended pin 263 which as the lever swings to the head 211 passes
beneath the inclined part or tooth 264 of a spring Jatch 265. The latch is pivoted
to the head at 266 and is depressed by a spring 267, 268 is standing stud upon
the top of the carriage having on it an anti-friction roller 269. The construction is
such that the stud 268, on the forward movement of the carriage, pushes the arm to
its outer position if the arm is not already in that position. The outer position of
the arm is shown in Fig. 6 and by broken lines in Fig. 8. When the side and heel
of the shoe are being worked upon the arm 259 is held in its outer position by the
pin 257 against which the inner side of the arm bears. When the toe of the last
comes to the position to be operated upon, the treadle 144 is depressed to the lower
position at the inner end which pulls down the pin 257 and releases the arm so that
it is drawn inward by the spring 262 and the pin 263 is carried beneath the
tooth 264. On the forward movement of the carriage the arm is forced outward
by the stud 268 and carries the head of the pincher rod into the position seen in
Fig. 8 when the pin escapes from the tooth and the arm is carried to its outer
position. On the return movement of the carriage a standing stud 270 on the fixed
frame engages a radial pin 271 upon the head and restores the pinchers to their
normal position. In case the pin 257 is in its depressed position when the arm 259
reaches its outer position the arm swings inward as soon as the carriage moves
backward and the stud 268 permits such inward movement of the arm and the
pin 263 again engages the tooth 264. In case the toe of the shoe has been finished
the treadle 144 is raised into the upper position at the toe and the pin 257
moves upward into the course of the arm 259 which passes over the top of the pin
in its outward movement depressing the pin in its passage and the pin after

page_text: depression is thrown up by the spring 256 and engages against the inner side of the
arm as before explained, to enable the forcing down of the pin 257 it is beveled at
top, the arm striking the lower part of the bevel. An equivalent construction
would be to bevel the part of the arm which strikes the pin. At 272 (Fig. 82) is
shown by dotted lines a spiral spring engaging a collar 273 on the rod 147 so as
to lift the rod and throw the treadle 144 into the position shown at 246 which
causes the parts to take position for lasting the side of the shoe. 274 is the guide
for the work, said guide extending beneath the fold 191 of the leather and Iving
on the insole with a small down-turned lip 275 engaging over the edge of the
insole. Now in lasting the toe and the heel it is necessary that the last should be
in a position nearer to the body of the machine than in lasting the sides, being
nearest when lasting the toe. The means for automatically changing the position
of the guide for this purpose will now be described. 276 is a screw rod turned
by a head 277 and carrying a collar 278 and a nut 279, the nut has a stud, 280,
carrying a friction roller, which engages in the worm of the cam 250 so that as
the cam is turned the screw rod is moved endwise in its socket 282 which is made
longitudinally in the fixed frame 153. The stud 280 projects through a longitudinal
slot 281 in the side of the socket 282 and engages the worm of the cam (250) as already
stated. The guide 274 is rigidly attached to the collar 278 and extends down-
ward through a longitudinal slot 283. The screw rod turns freely in the
collar 278 but is restricted from endwise movement therein by a tangential
pin 284 which passes through the collar and engages in a circumferential
groove 285 of the screw rod. The guide 274 is adjusted as to its mean position
(to and from the body of the machine) by the turning of the screw 276 in the
collar or nut 278, while the described inward and outward movement of the guides
as the work progresses is caused by the worm cam 250. In Figs. 9 and 82 the
treadle 144 and worm cam 250 are shown in the intermediate position, or position
for lasting the heel, the guide 274 being also in the intermediate position. If now
the treadle 144 be moved into the position indicated by broken lines at 248, the
worm cam will take the position shown in Fig. 10; and the guide 274 will be
then in the inner position, as required in lasting the toe. If, however, the
treadle 144 is moved, or allowed to move into the position indicated by broken
lines 246 (Fig. 82) the worm cam will be turned in the opposite direction to that
indicated by the arrow in Fig. 9 and no motion will be given to the rod 253, as
the wrist pin 251 will only move the length of the slot 252; the guide 274 will,
however, be moved outward by the rotary motion of the worm cam 250, and take
the position required in lasting the sides of the shoe.
The pinchers do not act while lasting the heel, and the device for throwing
them out of action will now be described. The rock shaft 249 carries at its fore
end a cam having projections 286 and 288 and a depression 287 between them.
When the side of the shoe is being lasted the position of the cam is as seen in
Figs. 20 and 21, the upper projection 286 being in action. The position of the
cam when lasting the heel is seen in Fig. 1, while the lower projection 288 is in
action in lasting the toe. The cam ac's against an anti-friction roller 289 at the
end of a sliding rod 290 transverse to the machine and connected at the opposite
end to a hanging arm 291 having a catch 292 which is inclined at the lower side
and horizontal at the upper side to engage a projection 293 on the lever 198 so
that when the roller 289 is in the depression 287 the catch 292 is in position to
arrest the descent of the lever and consequently of the sleeve 176 so that the
pinchers do not close. When, however, either of the projections 286 or 288 are
acting on the roller 289 the catch 292 is held out of the course of the pro-
jection 293 and the pinchers close upon the leather (191) at each descent. The
inner position of the arm is shown by the broken lines in Fig. 20; 294 is a draw
spring tending to draw it into this position and doing so whenever it is not held
in its inactive position by one of the cam projections 286 or 288, the ends of the
spring being connected respectively to the fixed frame and to a stud 295 upon the
rod 290

page_text: The presser-foot 296 is shown in detached views in Figs. 37-39. It has motion
in a vertical plane descending by a positive movement upon that part of the
leather which has just been made fast to the insole and preventing its being torn
up by the pinchers. 296 is the presser-foot connected by a vertical screw pivot 297
with the horizontal arm 298 of a bell-crank lever which is fulcrumed to the fixed
frame at 299. The upright arm 300 of the bell-crank carries an anti-friction
wheel 301 which is acted on by the peripheral cam projection 302 of the cam
wheel 171 to force down the presser-foot. The presser-foot is raised by a draw-
spring 303 by which the upright arm of the bell-crank is connected to the post 223.
The presser-foot is adjustable on the screw pivot 297 being drawn in one direction
by a draw-spring 304 by which its tail end is connected to the pin 305, the spring
holding the tail end against the point of a screw 306 turning in a bracket 307 and
held in place by a set screw 308. The presser-foot works in a very near proximity
to the folder.
The means for feeding forward the last to the machine will now be described.
The feed-finger 309 (like the guide) is curved around so as to engage the insole
beneath the edge (191) of the leather. It has a point 310 at bottom which engages
the insole on the descent of the finger after which the point moves forward
horizontally and then rises, at first vertically and then in an inclined upward
direction to a point from which it descends vertically to the insole. The several
positions are shown in Figs. 33-36. The feed-finger is attached to the spindle 311
having bearings 312, 313, in the face-plate 314 of the fixed frame. 315 are collars
fixed on the spindle and between them are the rounded ends 316 of the forked
end of the lever 317 by which the spindle has vertical movement. This lever is
fulcrumed to the fixed frame at 318 and carries at the rear end a cam stud 319
armed with an anti-friction roller which plays in a cam channel 320 of the cam
wheel 171.
321 is a horizontal arm fixed to the spindle 311 and passing through a mortise 322
at the fore end of an arm 323. The arm 323 is hinged at the rear end to a
sliding bar 324 which works endwise in a bearing 325 of the fixed frame. The
bar is actuated by the cam-wheel 171 through a stud 326 on the bar which works
in a cam channel or groove 327 of the cam wheel. By means of the cam wheel 171*
the feed spindle is given rotary oscillation.
.
328 is a torsion spring surrounding the spindle and having the upper end
connected with the upper bearing of the spindle, while its lower end bears against
the rear side of the arm 321. The construction is such that the spring acts to
throw the arm 321 outward. The inward movement of the arm 321 is limited by
a screw 321 which screws in an arm 321 extending horizontally from the spindle,
the point of the screw impinging against the frame when the arm 321 reaches its
outer position. The feeder should work as near as possible to the guide 274, and
the screw 321 gives means for adjustment in this respect. The degree of feed
movement is greatest when lasting the side of the shoe and least when lasting the
toe, while in lasting the heel the feed motion is intermediate. The means for
automatically changing the degree of the feed will now be described.
To increase or diminish the amplitude of oscillation in the arm 321 and
spindle 311, the slotted end or yoke 329 of the arm 323 is moved end wise of the
arm 321. For this purpose the cam-shaft 249 has an arm 330 which carries a
pin 331 engaging in an elongated bearing of a hanging arm 332 hinged to the fixed
frame at 333. The hanging arm is slotted at 334 for the passage of the arm 323
so that the position of the arm 332 governs the position of the yoke 329 upon the
arm 321. When the shaft 249 occupies the position for lasting the sides of the
shoe, the yoke 329 is at its farthest point from the free end of the arm 321 and
consequently the arm has the greatest amplitude of movement.
By turning the
shaft 249 into the position for the lasting of the heel the yoke 329 is moved to a
central position upon the arm 321 while when lasting the toe the yoke is moved to
the end of the arm 321. To still further lessen the amount of feed a recess 335 is
made in the outer side of the arm so that there is some lost motion of the arm in

page_text: the mortise 322, it being understood that the feed takes place when the arm 321
moves backward.
The machine has two rotary tack-boxes 336 and 336ª, the former containing
shorter tacks than the latter, the shorter tacks being for the sides of the shoe and
the longer tacks for the toe and heel. There are automatic devices by
which the proper tacks are furnished during the continued operation of lasting
the shoe all around. A description of one of the tack boxes will apply equally to
the other.
Especial reference is made to Figs. 48, 49, 50 and 51, for the details of
construction the position of the tack-boxes in the machine being clearly seen in
Figs. 1 and 6. The box has a cylindrical part 337 and a frusto-conical part 338
which may be made integral with the gudgeon 339. The gudgeon turns in a
bearing 340 being held therein by a screw 341. The part 337 is circumferentially
grooved at 342 for a belt 343 which passes around a grooved pulley 344 on the
cam shaft 160. 345 is a fixed head having a peripheral recess in which fits the
edge of the part 338, the head closing the front end of the box and giving bearing
to the tack-race and other things, (as will be hereinafter set forth) and forming a
front bearing on which the box turns. The part 337 has one or more interior ribs
or ledges 346 adapted to lift the tacks and drop them upon the inclined tack-race.
The tack-race consists of two parallel bars 347 inclined downward from their
ends 348, within the tack-boxes, to the place of delivery outside. The distance
asunder of the bars is such that the shank of the tacks will fall between the bars
while the head rests on the top of the bars. The upper edges 349 of the bars are
beveled upon the outside so that they come to an edge and give no place on which
the tacks can readily lodge. Each tack as it falls in position slips down the race
through the aperture 350 in the fixed head. 351 is a plate whose lower side is
parallel with the upper edge of the tack-race and such a distance therefrom as to be
just out of contact with the heads of the tacks. The two bars 347 are secured
together by screws 347" and are kept asunder by distance screws 347 the
screws 347 turning freely in one bar and screwing in the other bar, while
the screws 347 screw in one bar and their points bear against the inner side of the
other bar. 352 is a brush attached to a shaft 353 turning in the head 345, the
brush oscillating transversely to the race and brushing therefrom any tacks that
may not be in proper position. The shaft 353 extends through the head 345 and
carries outside the head an arm 354. The arm 354 carries a hammer 355 on a
flexible stem 356, the construction being such that as the arm (354) oscillates, the
hammer taps the tack-race and prevents the clogging of the tacks in the race.
The discharging ends 345 of the rotary tack-boxes both face inward. The driving
belt 343 of the box 336 is straight while the belt of the box 336* is crossed. The
belts run over idler pulleys 357: In order to oscillate the shaft 353 the shaft
carries a tappet arm 358 against which impinge the tappets 359 projecting from
the inside of the part 338 of the box, the rotation of the box bringing them in
contact with the arm 358. 354 is a draw spring connecting the free end of the
arm 354 with the head 345 and tending to restore the arm to the normal position
as the arm 358 escapes from the tappets 359 and carrying the hammer 355 against
the tack-race. Both of the tack-races are kept charged with tacks so that tacks may
be used from either of them. The tack-boxes have narrow slots 360 for the escape
of headless tacks and other useless matter.
The tack switching mechanism will now be described.
The longer tacks are used for the heel and toe, and the shorter tacks for the
sides of the shoe. It has already been said that the action of the guiding, feeding
and the drawing and crimping parts is modified automatically relatively to each
other by means of the treadle 144. The tack-switching mechanism is also
governed by the movement of this treadle 144 and associated mechanism simul-
taneously with the other parts. The shaft 249 has upon it an arm 361 loose on
the shaft. The arm is carried to the left of a person facing the machine, by a
spring 362, and is swung in the other direction by the pressure of a radial pin 363;
B

page_text: of the shaft, against a pin 364 upon the arm, see Figs. 1 and 72. It has been said
that the spring 272 carries the parts into position for lasting the sides of the shoe,
whenever the foot is removed from the treadle 144, and at this time the tack-race
of the box 336 is furnishing the shorter tacks for use, the pin 363 having pushed
the arm 361 to the right. For details of the parts of the tack-switch now to be
described, reference is made to Figs. 52 to 76 inclusive.
The free end of the arm 361 is hinged at 365 to a tubular bar 366 sliding in a
socket 367 of the base block 368 of the tack-switch. This block (368) is rigidly
attached to the fixed frame 153, by bolts passing through the recesses 369. The
tack-carrier 370 has a bottom plate 371 in which is fixed a round pin 372; the pin
has bearing in a socket 373 of a steel piece 374 which is fixed in and forms part of
the fixed block (368). The pin 372 extends above the top of the piece 374 and
passes through the hole 375 in one end of a shoe 376 which is rigidly connected to
the pin 372 by a pin 377 passing through the shoe and the pin (372). Thus the
shoe and the plate 371 are both rigidly attached to the pin 372 and oscillate
thereon in carrying the tack from either side to a central position. The plate 371
has a recess 378 at the front edge, which recess is spanned by a curved block 379
which is concentric at the inner face with the pivot pin 372. The piece 374 of the
fixed block extends forward in a projection 380 that is almost in contact with the
inner face of the curved block and which has a semi-cylindrical groove 381 which
forms with a similar groove in the block 379 a cylindrical passage 382, when the
block 379 is in a central position, as seen in Figs. 67 and 71. The size of the
passage 382 is such that the head of the tack 383 passes through it without
lodging. 384 is a plate secured to the top of the block 379 by the same bolts 385
by which the block secured to the extensions of the plate 371. This plate (384)
has a small recess 386 at its inner edge adapted to receive the shank of the tack
when the head of the tack is on top of the plate, in which position the tack is
delivered from the end of that tack-race which is in line with the notch; the end of
the other tack-race being closed by the unnotched edge 387 of the plate. Thus
tacks are furnished only by that race which is in line with the notch 386. The lower
end of the inner one of the parallel bars 347 of cach tack-race is secured in a
recess 388 cach side of the extension or projection 380, the side 389 of the
projection forming a continuation of that bar of the race; the outer race bar (347)
is continued in a line parallel with the side of face 389 extending to close
proximity with the block 379 so that the tack is delivered into the recess 386
which is of such size as to receive but one tack at a time. When the tack is
received in the recess the shoe 376 and plate 371 swing on the pin 372 sufficiently
to bring the tack to the groove 381 and the tack is drawn backward from the
recess 386 of the plate 384 and drops through the passage 382 into the recess of
the tack deliverer.
The means for slipping the tack from the recess 386 will now be described.
390 is a lever pivoted at 391 to a block 392 that is fixed on posts 393 standing on
the base block 368. The trip lever has a projection 394 against which impinges a
projection 395 of the carriage as the carriage is just reaching its rear position and
thus the rounded lower end 396 of the lever 390 is pushed backward. This end 396
works in an aperture of the sliding bar 397 having bearing in the block 392. To
the fore end of the sliding bar is connected by a hinge 398 an arm 399 bent
forward at the lower end 400 and having on the underside a catch 401 which
engages against the head of the tack as the arm is moved backward and pushes it
from the recess 386 into the passage 382 through which it drops into the recess of
the tack deliverer, as before explained. 402 is a spring which holds the arm 399
in its vertical position, as shown, except in the event of an abnormal obstruction
interfering with its backward movement, in which case the spring yields and
prevents injury.
The tack deliverer is rigidly attached to the carriage 163. It has a bar 403
which slides in a recess of the block 368. The bar has a vertical passage 404
which in the rear position of the bar is beneath, and in line with the passage 382

page_text: and in the main part of its length the same diameter as the passage 382 so as to
allow the tack head to pass down it easily. To the bottom of the bar 403 are
pivoted the jaws 405, the pivots being seen at 406. The tail ends of the jaws are
pushed asunder by a spring 407 which is seen inserted between them. The spring
keeps the fore end of the jaws pressed together and closes the bottom of the tack
recess which is made one half in each of the jaws. The recess is shown with a
cylindrical part 408 of equal diameter and in line with the passage 404 and a
conical lower end 409 which extends nearly to the under side of the jaws. Thus
when the jaws are in their rear position the point of the falling tack finds the
bottom of the conical part 409 of the recess, while the tack is kept in upright
position by the bearing of its head against the sides of the passage 404, see Fig. 64.
The passage 404 is preferably made in a steel bushing 410 and is made flaring at
the top so as to form a guide for the set 411 of the tack driver or hammer. When
the tack deliverer is in its rear position the boss of the bushing 410 is within the
recess of the plate 371 and is almost in contact with the lower side of the point 380.
As the carriage 163 and with it the tack deliverer reaches its forward position the
hammer descends and forces the tack downward, the jaws 405 spreading apart at
the fore end allowing the passage of the tack and the hammer, the tack passing
through the open slot or recess of the folder (207) into and through the edge 191
of the upper, and the insole 208. The set or point 411 of the hammer is fixed in a
vertically sliding rod 412 having bearings in the carriage 163, the rod is driven
down by a spiral spring 413 surrounding it, the lower end of the spring bearing on
a collar 414 upon the rod, and the upper end bearing against the carriage frame. The
upper end of the hammer rod carries a head 415 with a flanged top 416. 417 is a
spring dog hinged to the carriage at the lower end, and whose upper end is beneath
the flange 416 when the hammer is raised and serves to hold it in this position.
418 is a spring pressing the dog forward. 419 is a projection on the fixed
frame 153 against which impinges a pin 420 on the dog as the carriage reaches its
forward position, and by this means the dog is pushed from beneath the flange and
the hammer descends. The hammer is raised again, as the carriage moves
backward, by a lever 421, whose fore end 422 is forked and adapted to engage
beneath the head 415. The rear end of the lever is depressed by an incline 423
which acts on an anti-friction roller 424, the incline being a fixture of the fixed
frame 153. As the head 415 attains its upper position the dog 417 passes beneath
the flange 416 and the hammer is held up until the dog comes against the
projection 419 and the dog is again pushed from beneath the flange 416. The fore
end of the lever 422 is depressed by a spring 425. The lever 421 is fulcrumed on
a post 426 on the carriage.
The means for operating the tack-switch will now be described.
It has already been said that a single tack from the discharging end of a
tack-race enters the recess 386 and is by a movement of the switch carried to a
central position nearly over the passage 382 into which it is discharged by slight
rearward movement; it now remains to describe the mechanism for carrying the
recessed part 386 of the plate 384 to the proper tack-race. The shoe 376 has,
at top a recess 427 in which works a switch-tongue 428. The switch-tongue is
capable of limited oscillation on its end 429 which is shaped to fit in a rounded
recess 430. The tongue 428 has at its underside a stud 431 which projects through
a transverse slot 432 in the shoe and 433 in the block 368. The stud enters the
socket 367 passing through a slot 434 made endwise in the tubular pin or bar 366.
The stud is preferably oblong in section as seen in Fig. 73. 435 are headed pins
whose heads fits easily the bore of the bar 366 and bear against the edges of the
stud. 436 are spiral springs in whose adjacent ends are inserted the stems of the
pins so that these ends of the springs have bearing against the heads of the pins.
The other ends of the springs have bearing against the screw plugs forming the
ends of the bore. One of these plugs is seen at 463, the other plug carries the
ears forming part of the joint 365. This joint preferably includes a short link 365*

page_text: so as to avoid any binding of the bar 366 in its socket 367, the movement of
the bar being straight while the end of the arm 361 moves in the arc of a circle.
The endwise movement of the bar 366 causes the oscillatory movement of the
tongue 428, when the latter is free to move, when, however, the tongue is not
free, that spring 436, against which the stud 431 bears, contracts and immediately
the tongue is freed from its detent, the spring expands and throws the tongue to
one or the other side of the recess.
437 are stop pins or studs which project inwardly in sockets between the
pins 435 so as to limit the movement of the pins. The rear end 438 of the switch-
tongue is wedge-shaped, and adapted to receive the impact of a stud 439 upon the
carriage 163, said stud carrying preferably an anti-friction roller 440 which bears
against one side of the wedged end 438 when the carriage moves forward, and
moves the tongue and shoe to one side, the movement being such as to carry the
tack to its central position. The position of the tongue in its recess is determined
by the position of the arm 361 and the position of the tongue determines the
direction in which the stud 439 moves the tack carrier. In order to prevent the
stud 439 striking the salient angle 441 of the tongue, the tongue is always held
to one side of the recess of the shoe except when the carriage is in its rear position.
In order to do this the rear end 438 has at bottom a projection 442 that passes
through an aperture 443 in the shoe 376 and enters a recess 444 of the block 368.
445 is an arm hinged at the lower end 446 to the fixed frame and having a pin 447
connected by a draw-spring 448 with a pin 449 upon the fixed block 368; the
spring acting to draw the top of the arm forward. 450 is a point upon the arm
which enters the recess 444 and prevents any change in the position of the tongue
till the point 450 is moved backward. The backward movement of the upper end
of the arm is accomplished by a projection 451 of the carriage, which impinges
against the projection 452 of the arm as the carriage is just reaching its rear
position, so that if the arm 361 is moved at any time except when the carriage is
in its rear position the switch tongue remains at rest until the carriage reaches its
rear position, when the tongue is immediately reversed and ready for the stud 439
with its roller 440 to act on the other side of the wedge-shaped point. Thus in no
case can the stud-roller 440 strike the salient angle of the point as it does not
reach the point until the projection 451 has been carried out of contact with the
projection 452, and further the point 450 always precedes the stud 439 in the
forward movement of the latter.
In Fig. 68, the parts are shown in position to take the tacks from the box 336,
while in Fig. 69 the parts are in position to take the tacks from the box 336*. In
Fig. 70 the carriage is in its forward position, while in Fig. 71 the carriage is in
its rear position.
It is proper that the machinery should come to rest speedily when desired, and
in a position most favorable to the application of the shoe to be lasted; and I will
now describe the brake mechanism, which is shown in Fig. 90. The treadle
lever 119 is keyed to the shaft 120 which forms the fulcrum of the lever. This
shaft has bearing in the side of the frame 101 and carries upon the outer side of
the frame an arm 453 having a pin or stud 454 bearing or adapted to bear against
the underside of the arm 455 of a bell-crank lever fulcrumed at 456 to the
frame 101. The upper arm 457 of the bell-crank carries a friction shoe 458 con-
nected to the arm 457 preferably on a pivot 459 and bearing against the periphery
of an eccentric 460 keyed to the cam-shaft 160. The free end of the arm 455 is
connected by a draw-spring 462 to a fixed point on the frame 101 beneath, so as to
draw down the free end of the arm (455) whenever the treadle lever 119 is in its
forward position and consequently the arm 453 is in its lower position. This
position of the parts is shown in full lines in Fig. 90, the brake shoe being forced
against the eccentric with the whole force of the spring 462 and the cam-shaft is
brought to rest before the salient part 461 of the cam has passed the shoe. If the
force of the spring is not. great enough to prevent a single passage of the salient

page_text: part 401 beneath the save to alter one
no injury is done to the mechanism for the spring 462 allows the shoe to move
outward.
The position shown by broken lines in Fig. 90 is the position of the parts when
the machine is running.
