A communication by SINNING LASTING MACHINE COMPANY, of St. Louis,
Missouri, U.S.A.
I, ALBERT WILLIAM WALLACE MILLER, of South Orange, New Jersey,
U.S.A., but at present at Manhattan, Rainhill, in the County of Lancaster,
England, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements on the machine already patented
in Patent No. 1240691.
It is best described in reference to a machine actually constructed (and imported
by me to this country, for the purpose of obtaining a patent thereon).
The following are the principal differences between this machine and the machine
set forth in the aforesaid Patent :-
In order to enable the pinchers to take different thicknesses of leather the cam
which regulates the two pinchers has bearings in two side plates having lugs with
elongated slots. In these slots are pins, each of them having a roller pressing
against one of the jaws on the outside, a spring presses these two pins together and
will therefore give way to the necessary amount for different thicknesses of
leather. The collars on the pincher shaft and the pincher sleeve, by which the
lever lifts and lowers the pinchers are adjustable; by this means the exact height
of the pinchers can be adjusted.
The feeding of the tack is arranged in the following manner & by the following
apparatus: From a pulley alongside the main driving pulley a small countershaft
below the principal countershaft of the machine is driven by means of another
pulley and belt. This driving pulley is loose on the shaft but has a sufficient
amount of friction to raise the shaft when it is not locked. On the shaft is a disc
having four slightly excentric slots in which four blocks are fixed by means of set
screws. These project a little beyond the centre so as to form teeth. A bell-
crank pulley works in connection with the disc in such manner that one or other of
its pawls such catch on one or other of these teeth, it is in fact an escapement pawl.
This escapement is linked by a rod to a handle in front and is held in place by a
spring, consequently by touching this rod or trip lever the disc is allowed to take
one turn. The disc has an excentric pin on which works a link connected by two
ball joints with a crank; this crank is on a shaft hereafter called the side shaft.
On this shaft is a cain working on a cam fork working in a groove in a sliding bos
on the main shaft; this sliding bos has attached to it the closing cam for the
pinchers hereafter to be described. On the side shaft are two loose collars. The
first is held in place by a coiled spring round the shaft but is free to turn to a
certain extent; the second alongside this first collar has an arm attached to it
working the mechanism that changes the tack. The motion of these two collars on
the shaft is limited by a spring working against a projection on the one collar, and
the arm cn the other collar. The first collar, the one without the arm, has a
bracket formed in one with it overlapping the spring and projecting upwards.
Beyond these two collars is a third collar keyed to the shaft; on this is the cam
used for changing the feed and for throwing the actuating cam out of position.
The feed changing cam has a V shaped groove in which works the bowl of a radius
link attached to the frame near the top. On this radius link is a pin which at
certain portions of the stroke comes in contact with the bracket on the first of the

page_text: above mentioned collars. The radius link has a transverse slot a little above the
middle of its length in which works the pin of a second radius link attached to
the first radius link near the top. On the bent end of this second radius link is a
large slot in which works the feed crank lever. The feed crank lever is linked by
a universal joint to a rod having a bowl on the end working on a cam on the
main shaft; at the other end it has a short slot through which projects the feed
crank,
The arm attached to the middle collar on the side shaft is linked at the end to a
pin which works the tack switch and thus connects one of the raceways or the
other as the case may be with the tack distributor. The top part of the machine
is driven by means of a belt and a loose pulley on the main shaft of the upper part
of the machine; this pulley can at any time be brought into action by a friction
clutch. The friction clutch is actuated by a bell crank lever and two toggle joints
below. The pulley is provided with a friction clutch which is ordinarily held in
gear by a spring in a hollow in the main shaft acting against a cotter passing
through the shaft. It is thrown out of gear by means of a clutch lever which
throws the clutch out of gear when actuated by a bell-crank one arm of which is
acted upon by a cam on the main shaft; the other arm is linked to a toggle joint
which again is jointed to another toggle joint below, which again by means of a
bell-crank is connected with the wire connecting rod hereafter described. On the
upper toggle joint is adjusted a brake; this brake is supported on a lever from a
convenient point in the frame and when the toggle joints are straight one over the
other, presses the brake shoe on it against a brake cam on the clutch. The toggle
joints have only a limited range in order not to pass the dead point consequently
the wire connecting rod can very easily throw the clutch out of gear. It will thus
be seen that the main shaft will run continuously so long as the cam thereon cannot
come in contact with the bell crank, but the moment the wire connecting rod is
released and allows the crank pin to rise, the bell crank by means of the toggle
joints comes in contact with the cam on the main shaft and the clutch is at once
brought out of gear and the brake applied.
The raceways for the tacks are now made out of one piece with the lid attached
thereto by means of a bracket. The feed link lever is worked by a cam on the
main shaft and is connected direct to the crank instead of being jointed as formerly.
The abutment against which the shoe to be lasted is held, consists of a piece of
stout leather fixed in a metal tip adjustable on a rod by means of a set screw and
pin. This rod is supported by two cranks from the base plate which have a limited
motion. This motion is termicated in one direction by an arm which comes in
contact with the base plate and on the other end of its range by an adjustable
screw pin its motion is caused by the sliding frame coming in contact with it or
with a roller on an arm fixed to it. A spring holds the bar in the forward position
except when forcibly pressed back by the sliding frame. The arrangement for
adjusting the tack is as follows:-The tack comes down the raceway and falls into
the notch in the tack plate, the tack plate is now shifted until the stationary half-
bush and the upper part of the tack carrier come into contact; when this takes
place the tack distributor comes in contact with an abutment and is thus
pressed back, the tack falls down through the bush into the tack carrier
and is held by the jaws, the tack carrier now comes forward with the tack
until it comes into position for driving. The driving mechanism is also new. The
spindle of the driver has on its head a plate which at certain portions of the
stroke rests on a dog. The head is linked to a lever pivoted on the sliding frame
the other end of this lever works on a cam on the stationary frame in such manner
that as the sliding frame comes backward the cam presses down the free end of the
lever raising the driver head above the dog, as the sliding frame goes still further
back a pin on the pivoted dog comes in contact with an abutment on the stationary
frame and presses the dog under the plate. As the sliding frame again comes
forward the plate on the head rests on the dog, coming still further forward a cam
keyed to the spindle on which the lever is also keyed comes in contact with a radius

page_text: arm on the main shaft held back by a powerful spring; the sliding frame travelling
still further the pawl is held from advancing by this arm, at the same time the pin
on the dog comes in contact with another abutment on the stationary frame. The
result is that a momentarily very powerful pressure comes on the lever tending to
press the driver down, while immediately afterwards the dog is liberated and the
driver descends. The arm is prevented from going too far by an abutment and the
lever to which the spring is attached is adjustable by means of a screw so that a
greater or lesser tension can be used as required.
The pincher cam instead of being a single solid piece has the operating portion
adjustable on a ring concentric with the axis by means of a screw. By this means
the operative portion can be brought further forward or backward as the case may
be and thus the pinchers will release the leather at an earlier or later portion of
the stroke. Below the free end of the lever actuating the driver is placed a spring
cushion. By this means the driver is-kept down upon the dog while the end is free
and thus the play that would otherwise form and which is necessary in order to
enable the dog to enter below the plate is taken up. In order to still further lessen
the friction on the dog a piece of oiled felt is fixed to the lever and placed above
it so that at each freeing of the dog it shall come in contact with the felt and reoil
itself. The abutments of the pin are adjustable. The cam that works the sliding
frame instead of being almost a sharp angle is now made very much rounder; by
this means the jerking of the machine formerly experienced is avoided. When it
is desired to put more strain upon the leather this is done by means of an oil pump
hereafter described in the following manner :-The lifting lever of the pinchers is
attached by means of a coiled spring indirectly or directly to the piston rod of the
pump. The head of the piston rod has attached to it a rod connected by link
motion with an indicator. working in the front of the machine and in view of the
operator. The head has also attached to it a link working the crank of a third spindle
on which works an excentric regulating the lift of the pinchers, it being supplied
with a couple of jaws sliding on opposite sides of the lifting lever, which is supplied
with short abutments to keep those jaws in place.
The following is a description of the pump :-Two wheels gearing into each
other similar to a Roots blower in some respects drive the oil into the valve. The
valve has three ports, first one in the centre passing right through from side to side,
secondly one on one side also passing through from side to side parallel with the
first and having a port hole, the third passes through from one side only and has a
port below. This third port below connects with the other side of the wheels by
means of a passage; the remaining bottom port connects with the lower port of
the pump barrel; the port passing direct through the valve connects with the
upper port of the pump barrel. The mode of action therefore is as follows:-
When the valve with the centre ports are in line with the entrance the piston is
caused to descend; when in line with the side port having only an opening below,
the wheels simply revolve without doing any work; the oil pumped by tube instead
of going into the piston valve goes back again to the other side of the wheels
while if the third port be used the oil passes below the piston and raises it. The
lid of the piston barrel, valve chest and pump proper is perfectly flat, the spindle
of one of the two wheels rises up through the bush in it and carries a bevil wheel,
and is driven by means of a pinion on a cross shaft by means of the belt which
drives the main shaft and is continually kept running. The oil is prevented from
working up through the spindle hole by the lid being made hollow and a continuous
passage being formed from the one bush to the other; from this passage a further
passage descends to the hollow in the pump proper from which the oil is withdrawn
by the wheels. The arrangement of treadles is new, there being no less than three
operating together, first a primary treadle having an arm working the valve of the
pump, secondly, a secondary treadle hinged to the same shaft, resting ordinarily on
the primary treadle, and thirdly a hanging kick-off treadle. The primary treadle
has a projection on it passing up through a loop in the secondary treadle. The
hanging treadle also has a stud or projection passing down through this loop. The

page_text: hanging treadle is governed by a spring tending to pull it forwards, the secondary
treadle by a spring tending to pull it upwards and the primary treadle by a spring
also tending to press it upwards, which however has no power on it at its highest
point. The secondary treadle is attached by the connecting wire to the toggle
joint. The mode of action is as follows:-To start the machine the main treadle
is pressed down, this presses down the secondary treadle with it and thus the toggle
joint and starts the machine. At the same time it allows the kick-off treadle to
lock in the secondary treadle. If now the strain on the leather has to be increased
the operator presses down the main treadle; this turns the valve and the piston
descends, the indicator shows the strain on the leather. When the required strain
is reached the operator presses down the main treadle rapidly and thus stops
further entry of oil into the piston barrel until such time as the main treadle is
released, the moment however the main treadle is released it rises and the oil
passes through to the top of the piston lowering again.

Referring to the drawings :-
-
1 represents the main frame of the machine, upon which is mounted the movable
head 2, and a fixed head 3.
4 represents the nippers consisting of a pair of bars pivoted to a spindle or
shaft 5, at 6, and having their lower ends serrated, as shown at 7, so that they will
take a firm bite upon the leather to draw it into position over the last. The
spindle 5 is threaded at 8, to receive a grooved collar 9, that fits the forked end of
a lever 10, which is pivoted at 11 to the movable head 2, (see Figs. 1, 2, 4, 18
and 42). The end of the lever at the collar 9 is forked to fit in the groove of the
-collar, as shown at 12, Fig. 4. As the lever 10 is oscillated on its pivot 11, it will
impart a vertical movement to the spindle 5, and through the spindle will cause a
vertical movement to the nippers 4. The collar 9 has a threaded connection with
the spindle 5, as stated, and it is provided with means for turning it so that its
vertical position on the spindle can be changed to regulate the rise and fall of the
nippers under the action of the lever 10, as, for instance, if the collar is moved
upwardly on the spindle, the nippers will be moved to a lower point, and not
ascend as high, and by moving the collar down on the spindle, the nippers will not
-descend as low, and will ascend to a higher point. The distance of movement of
the nippers will be the same in each case, but the points to which they move to
will be different. As a means for turning the collar 9, it has been shown provided
with sockets 13, into which a key or short lever can be inserted.
14 represents a sleeve fitting the spindle 5 and having a loose bearing at 15 in
the head 2. The sleeve 14 is adapted to move vertically with relation to, and
independent of the spindle 5, and it is thus moved by means of a lever 16 pivoted
to the head 2 at 17, (see Fig. 18). While the sleeve is permitted to move vertically,
it is held from horizontal movement or rotation by means of a set screw 18 passing
through the bearing 15 and fitting in a groove 19 of the sleeve. The sleeve has
downwardly extending arms or extensions 20, upon the lower ends of which is a
head 21, provided with a fixed central roller 22, and movable lateral rollers 23.
The gudgeons or journals of the rollers 23 fit in slots 24 in the head 21, and
these rollers are held against the outer surface of the pinchers by means of
springs 25, (see Figs. 18 and 42). The jaws of the nippers extend beneath the
head 21 and extend through the head, as shown in Fig. 42. The central roller 22
is between the jaws. When the nippers are ready to take the leather, the sleeve 14
descends, carrying the head 21 with it, and the jaws are closed by the
rollers 23 bearing against the outer surface of the nippers, and to provide for a
positive movement of the sleeve 14, without danger of breaking any part of the

page_text: machinery, the rollers 23 are mounted in the slots 24 of the head 21 and the
springs 25 are provided, which tend to keep the rollers in their inner position, but
which will permit them to yield under excessive pressure, and thus different-
thicknesses of leather may be grasped by the nippers, without danger of breakage
even though the sleeve is moved by a positive action. When the sleeve ascends.
relatively to the spindle 5, the roller 22 serves to open the jaws of the
nippers.
It will be seen that the nippers will not be permitted to turn horizontally, from
the fact that they are themselves flat or non-circular and pass through the flat
head 21, which is formed upon or secured to the sleeve 14 that is held from turning-
by the set screw 18.
The end of the lever 16 is bifurcated and fits in the groove of a collar 26 threaded
on the upper end of the sleeve 14. The collar 26 can be adjusted to regulate the
movement of the sleeve, and it is shown provided with sockets 27, to receive a
lever or tool by which it can be turned. The sockets 27 of the collar 26, and also
the sockets 13 of the collar 9 are threaded, as shown in Fig. 42, so that when the
collars have been adjusted respectively on the sleeve 14, and spindle 5, they may be-
held to their adjustment by means of set screws 28, fitted in the sockets, (see Fig. 1
and Fig. 42). Each collar is provided with a number of the sockets to receive
the lever for turning the collars, (the lever being inserted in the socket most
accessible at the time,) and the set screws fit in any of these sockets.
The lever 10 is moved on its pivot 11, to operate the spindle 5, by means of a
cam 29, shown clearly in Fig. 18, the lever having a projection or cam roller 30,-
bearing against the cam and held against the cam during the first part of the
movement of the cam, by means of a spring 31 connecting with a pump, which will
be hereinafter particularly referred to. The cam 29 is mounted on a shaft 32 and
as it moves against the projection 30 to a point substantially at A, Fig. 18, it
causes the descent of the spindle 5, which lowers the nippers to a position to grasp.
the leather. As the cam 29 continues to turn against the projection 30, from the
point A to the point B, the spindle remains in its lower position, and as the cam
continues to move beneath the projection 30, from the point B, the spindle begins.
to rise under the influence of the spring 31, and it is now that the leather is being
pulled in an upwardly direction by the nippers. When the nippers are in their
lower position, and before they commence to rise, the jaws of the nippers are
caused to close by means of the lever 16, (which moves the sleeve 14 as explained)..
The lever is operated by cams 33, 34, on the shaft 32, (see Figs. 18 and 30 to 35)..
The cam 33 has a groove 35 in which a projection 36, (which is preferably in the
form of a friction roller) on lever 16 fits, and the outer surface of this cam groove,
from C to D, Fig. 18, is what causes the movement of the lever 16 to effect the
descent of the sleeve 14; this portion from C to D comes against the projection 36 of
the lever 16, while the projection 30 of the lever 10 is riding on the cam 29
from A to B. As soon as the point D leaves the projection 36, the lever 16.
becomes inoperative, and the sleeve 14 is raised, with the spindle 5, by the
lever 10, as the cam 29 from B to B moves under the projection 30 of the lever,.
the cam not acting to produce the descent of the outer end of the lever, but simply
to effect or cause its gradual descent under the action of the spring 31, which pulls
the projection 30 onto the surface of the cam from the point B to E, and the
descent of this end of the lever is accompanied, of course, by the ascent of the
other end of the lever and the spindle 5. As the spindle 5 ascends the jaws
of the nippers continue to hold the leather, and draw it over the last. It has been
stated that the lever 16 is inoperative during the ascent of the spindle, but
nevertheless the sleeve 14 continues to hold the jaws of the nippers in their closed
position, although the sleeve, (during the ascent of the spindle) is not under the
pressure of the lever 16. The sleeve thus acts to hold the jaws closed, although
the pressure is removed from the lever 16, owing to the fact that the outer faces of
the jaws are formed with substantially vertical portions 37, (see Fig. 42), against
which the rollers 23 bear when the sleeve 14 has been forced to its lower position,.

page_text: relatively to the spindle 5, and thus it will be understood that although the pressure
of the lever 16 is removed from the sleeve 14, the rollers 23 will continue to hold
the jaws of the nippers or pinchers closed until the sleeve 14 is raised, by a positive
movement, relatively to the spindle 5. The lever 16 being thrown out of operation,
after it causes the descent of the sleeve 14, leaves the lever 10 to lift the spindle 5
and sleeve 14 together, or at the same time.
When the cam 29, at the point E, leaves the projection 30 of the lever 10, it
ceases to operate on the lever, and the head 2 now begins to move forward to draw
or pull the leather over the sole of the last. This forward movement of the head 2
is effected, (see Fig. 29), by means of a cam 38 on the shaft 32, which bears
against a projection 39, (which is preferably in the form of a friction roller,)
extending from an arm 40 secured to the head 2, as shown. Almost immediately
after the head 2 commences to move forward, the abrupt surface 41 of the cam 34
comes against the projection 36 of the lever 16, and causes the sleeve 14 to be
raised on the spindle 5, and the jaws of the nippers are thus opened and release
the leather, which is now forced down onto the last, as the head 2 continues to
move forward, by means of a folder 42, (see Figs. 18 and 42). For the purpose
of causing the nippers to release the leather sooner or later, the cam 34 is secured
adjustably on the hub 43 of the cam 33; the cam 34 having a collar 44 fitting over
the hub, and which is tightened by a suitable clamp 45, see Fig. 30.
The cam 33 has a gap 33", (see Fig. 31), which is filled by the body of the
cam 34, with sufficient play to permit the cam 34 to be adjusted, as stated. The
periphery of the cam 34 has a rim 34ª, forming a continuation of the outer wall of
the groove 35 in the cam 33, and the ends of rim 34° are notched to overlap the
notched ends of the rim on the cam 33, as shown at 46, Fig. 33, and thus the outer
wall of the groove 35 is continuous across both cams. The face of the cam 33 has
a recess 47 to receive the surface or part 41 of the cam 34. When the head 2 has
returned to its inner position, the cam 29 comes against the projection 30 again,
as shown at 48, Fig. 18, and the operation of the levers 10 and 16, with their parts,
is repeated. While the head is in its forward position, the tacks are delivered and
driven as will be hereinafter explained.
The construction of the pump by which the projection 30 of the lever 10 is held
toward the periphery of the cam 29 from B to E will now be described.
The construction of the pump is shown in the drawings from Figs. 65 to 72, and
its connection with the machine is shown in Fig. 16, while the manner of driving it
from the main shaft of the machine is shown in Figs. 3 and 16.
50 represents the cylinder of the pump having a port 51 forming a com-
munication between its bottom and a chamber 52 located at the upper end of the
cylinder. The port 51 communicates with the chamber 52 through means of a
horizontal passage 53. 54 represents a valve located between the upper end of the
cylinder and the chamber 52, the chamber having an opening 55 opposite the valve,
and the cylinder having an opening 56 opposite the valve.
57 represents the piston of the pump, and the stem 58 of the piston is connected
to the spring 31 above referred to, as shown at 59, Fig. 16.
60 represents a bushing fitting in the upper head of the cylinder, and extending
a distance into the cylinder, as shown, so as to prevent any possibility of the piston
rising so far as to cut off the opening 56. The upper head of the cylinder and the
top of the chamber 52 are formed by the bottom 61 of a chamber 62, located over
the cylinder and over the chamber 52. The piston rod 58 passes through this
chamber 62, as shown in Fig. 67, and on top of the chamber 62 is a tube 63
through which the piston rod also passes. The internal diameter of the tube 63 is
somewhat larger than the diameter of the piston rod, so that any liquid carried up
by the piston rod will travel down it again, and be caught by the tube, and carried
back into the chamber 62, or in other words, by making the tube 63 larger than
the piston rod, its upper end does not scrape or remove the liquid from the
piston rod, but such liquid as is carried up on the rod gravitates back into the
chamber 62.

page_text: 64 represents the pump wheels of the pump, located in the chamber 52, and
which force or conduct the oil to the valve 54, the wheels turning in the direction
of the arrows, Fig. 66, and the spaces between the teeth being filled with oil,
while such spaces at the adjacent sides of the wheels are occupied by the teeth
of the wheels, and the oil thus displaced at the valve side of the wheels, as will be
plainly seen.
One end of the journal or arbor of one of the wheels is extended through the
top 65 of the chamber 62, and has upon it a bevel wheel 66 engaged by a similar
wheel 67 on a shaft 68, journalled to the lower end of the frame 1 of the machine,
and which is driven by a belt applied to a pulley 69, from a suitable motive power,
(see Fig. 3). The stem 70 of the valve 54 extends through the top 65 of the
chamber 62, (see Fig. 67), and has upon it a crank 71, (see Fig. 68), which is
connected to a treadle 72 by means of a bracket or standard 73, and a link 74,
(see Fig. 16). The form of the valve 54 is illustrated in Figs. 67, 70, 71 and 72.
It has a straight passage 75 which forms a communication between the chamber 52
and the upper end of the cylinder 50. On one side of the passage 75 is a vertical
passage 76, communicating through an opening 77 with the chamber 52, when the
valve is turned in the proper position for this communication. The lower end of
the passage 76 communicates with the passage or port 53, as shown in Fig. 72.
On the other side of the passage 75 is a passage 78, which also communicates with
the port 53 at bottom, and which has an opening 79 adapted to register with the
opening 56 in the upper end of the cylinder 50, and an opening 80 adapted to

position shown in Fig. 67, the liquid passes from the chamber 52 into the upper
end of the cylinder 50, above the piston 57. When the valve is in the position
shown in Fig. 70, the liquid passes from the chamber 52 into the port 53, and of
course back again into the chamber 52, and at this time the liquid is also allowed
to pass from the upper end of the cylinder into the chamber 52, through the

the piston is in the position shown in Fig. 71, the liquid is permitted to pass
from the chamber 52, into the port 53, and back to the chamber, while the liquid
is not allowed to escape from the upper end of the cylinder, the piston 57 at
this time being held against the tension of the spring 31 by the body of liquid
above it.
When the valve is in the position shown in Fig. 67, the piston 57 is, of course,
under the influence of the action of the wheels 64, but when the valve is in either
of the positions shown in Figs. 70 or 71, the action of the wheels 64 does not affect
or act upon the piston 57, and thus the pump is allowed to run continuously, what-
ever the desired condition of the piston 57 may be. The different positions of the
valve 54 are effected by the operator, through the treadle 72, and he can effect, at
will, a downward movement of the piston 57, (by moving the valve to the position
shown in Fig. 67), or permit an upward movement of the piston 57, (by moving the
valve to the position shown in Fig. 70), or he can cause the piston 57 to remain at
rest, (by moving the valve to the position shown in Fig. 71).
By locating the chamber 52 at the upper end of the cylinder 50, with but
the small space occupied by the valve 54 between them, the different actions of the
piston 57 occur almost simultaneously with the movement of the valve 54. The
chamber 62 provides a reservoir for surplus liquid, and the tube 63 communicating
with the chamber 62 avoids any escape of liquid from the pump. In practice, the
are, of
chamber 62 is kept about half filled with liquid, while the parts beneath
course, all full of liquid.
In operating the machine, the operator applies his foot to the treadle 72. The
first movement of the treadle, (the pump being in operation,) shifts the valve 54 to
the position shown in Fig. 67, causing the descent of the piston 57, and through
means of a dial on the front part of the machine, the operator is informed of the
tension upon the spring 31, caused by the descent of the piston 57. He then
forces the treadle 72 to its lowest position, the first movement just referred to being
B

page_text: about half of the throw of the treadle. As a means of indicating to the operator
that he has moved the treadle the first half of its throw, a treadle controller is
employed consisting of a rod 81, (see Fig. 16,) which passes through an arm 82
projecting from the frame 1.
Between the arm 82 and a collar 83 on the upper end of the rod is a spiral
spring 84, and on the rod, beneath the arm, is a collar 85. On the lower end of
the rod, beneath the treadle 72, is a nut or collar 86, between which and the
treadle, when the latter is in its upper position, there is a space, as shown in
Fig. 16. The treadle is held in its upper or normal position by means of a suitable
spring 87, (see Fig. 16), or by means of a weight 87, (see Fig. 36).
When the operator depresses the treadle until it comes against the nut or
collar 86, he feels the resistance of the spring 84, and is thus informed that he has
moved the treadle sufficiently far to open a communication between the chamber 52
and the cylinder 50 of the pump. He then allows the parts to remain for a second,
until the indicator shows the desired pressure: he then forces the treadle all the
way down, and in doing so a projection or lug 88 of the treadle (see Fig. 17),
comes against a cross bar or projection 89 on a lever 90, pivoted to the frame 1,
with the treadle, at 91. The lug 88 comes against the projection 89 before the treadle
reaches the limit of its downward movement, and the lever 90 is carried down
with the treadle, and throws the machine into operation through means of a clutch
hereinafter to be described, the lever being connected to the clutch through means
of a rod 92.
When the lever reaches the limit of its downward movement, a bar 93 hinged to
the frame 1, at 94, is pulled by a spring 95 into a notch 96 in the free end of the
lever 90, and this bar holds the lever 90 in its lower position while the trendle 72
is permitted to vibrate to effect the different conditions of the pump, as explained.
When it is desired to release the clutch and stop the machine, the operator presses
against a foot-piece 97 on the bar 93, and forces the lower end of the bar out of the
notch 96, permitting the lever 90 to rise and the clutch to be thrown out, and when
the operator removes his foot from the treadle, it is drawn back by the spring 87
to its normal position shown in Figs. 16 and 17, when the valve 54 assumes the
position shown in Fig. 70.
It will be noted, by referring to Fig. 18 that from the point B of the cam 29,
the periphery of the cam recedes toward the center of the shaft 32, and as already
stated, it is at this time that the leather is being drawn over the last, and at this
time the cam may or may not bear against the projection 30 of the lever 10,
according to the tension of the spring 31, applied by the pump. Ordinarily the
cam at this time does not bear against the projection 30, but leaves the lever 10
under the control of the tension of the spring 31. Some leathers require more
pressure or require to be drawn harder or with more force than other leathers, and
the operator has this entirely under his control by increasing or decreasing the
tension of the spring, or holding it at a uniform tension through means of the pump
which he controls and manages by the treadle, as explained, so that while the
nippers are forced to their lower position, and held there a short time by a positive
movement, while the cam is passing under the projection 30 to B, from here on,
the ascent of the nippers is entirely under the control of the operator through the
medium of the pump.
The upper end of the piston rod 58 has a cross-head 100, (see Fig. 3).
101 represents a shaft secured to the frame 1 of the machine by means of journal
boxes 102. On this shaft is a crank 103, connected to one end of the cross-head 100
by means of a rod 104. On the shaft 100 is also an eccentric 105, (see Figs. 3
and 16), around which passes a strap 106, from which extends vertically a rod 107.
This rod is forked at its upper end, as shown in Figs. 1 and 3, to receive the free
end of the lever 10, the rod being held from movement end wise on the lever by
means of pins 108. The arrangement of these parts is such that when the
piston 57 descends, the salient part of the eccentric 105 turns downwardly and
consequently the rod 107 falls with the piston, and when the piston ascends, the

page_text: salient part of the cam turns upwardly, and the rod 107 ascends. The function of these
parts is to form a stop for the outer end of the lever 10, and consequently for the
upward pull of the nippers on the leather, and the stop thus formed is constantly
shifting in accord with the tension of the spring. The outer end of the lever 10
can at no time descend farther or be pulled down farther by the spring 31 than the
base or bottom of the crotch of the fork of the rod 107.
In lasting certain kinds of shoes, the leather has to be pulled up more with the
nippers than with other kinds of shoes, and some leathers will stand considerable
stretching, while others will stand much less. By providing the rod 107, the
operator regulates the tension of the spring 31, and simultaneously shifts the
rod 107, and if the tension of the spring 31 is greater than the leather will stand,
there would be danger of tearing the leather were there not a limit to the
downward movement of the outer end of the lever 10, or in other words, a limit
to the upward movement of the nippers. This construction provides a stop to
limit the movement of the nippers, and the stop is constantly changing with the
position of the piston of the pump and the consequent tension of the spring 31.
The
The construction of the clutch arrangement, which is operated through means
of the treadle 72, lever 90, and rod 92, as heretofore mentioned will now be
described. This clutch arrangement is shown in the drawings, in Figs. 20 to 28
inclusive, and its application to the machine is shown in Figs. 2 and 3.
forms shown in Figs. 2, 3, 27 and 28 differs somewhat from the form shown in
Figs. 20 to 25 inclusive. The latter form will first be described. The rod 92 is
connected to one end of a bell-crank lever 110, which is pivoted at 111 to the
frame of the machine. The end of the lever which does not have connection
with the rod 92, is pivoted at 112 to a link 113; this end of the bell-crank
lever and the link forming a kind of toggle. The upper end of the link is
connected by a bolt 114, and a bar or second link 115 to the inuer end of a
bar or link 116, the outer end of the bar or link 116 being pivoted at 117 to
the frame of the machine. The link 115 is connected to the link 116 by means
of a bolt or pin 118. 119 represents a bell-crank lever pivoted to the inner
end of the link 116 by means of the pin 118. One end of this bell crank lever
is bifurcated, or forked, to fit in the groove 120 of the hub 121 of the clutch 122.
The other end of the bell crank lever 119 is provided with a friction roller 123,
adapted to be engaged by a cam 124 secured to the shaft 32 upon which is also
mounted the recessed pulley 125, with which the clutch engages.
110ª represents a spring connecting the joint between the upper end of the bell
crank lever 110 and the link 113 to the frame of the machine, as shown in
Fig. 20. The pulley 125 has a conical or tapering recess to receive the
clutch 122, as shown in Fig. 28.
The end of the shaft 32 is recessed to receive
a spring 126, (see Fig. 28) which has bearing between a plug 127, tapped into
the outer end of the shaft, and a head 128 on the inner end of a rod 128 fitting in
the hollow part of the shaft. The head 128 bears against a pin 129, fitting in
slots 130 in the shaft, at its hollow part, the outer ends of said pin fitting in per-
forations in the hub of the clutch 122, one end of the pin being shown at 131,
Fig. 22. When the lever 90 is depressed and held in its lower position by the
bar 93, (which is the time the machine is working,) the bell-crank lever 119 is
pulled down into the position shown in Fig. 23, so that the outer end of the
lever cannot be engaged by the cam 124, as the shaft revolves; and at this
time the clutch is held into frictional contact with the pulley 125 by means of
the spring 126, the operating parts of the machine being now driven through
the shaft 32, turned by the pulley 125, and the clutch 122; the clutch having
feather and groove connection with the shaft, as shown in Fig. 28, while the pulley
is loose on a collar 133, keyed to the shaft. The shaft 32 is driven by the pulley
through the means of the clutch, (when the clutch is in engagement with the
pulley) by means of a belt 134, passing over the pulley and around a pulley 135 on
the shaft 68, see Fig. 3.
The tension of the spring 126 is sufficient to hold the clutch against the

page_text: pulley 125, with sufficient force to insure the turning of the shaft 32 through means
of the pulley and clutch. When the lever 90 is released, the spring 110° draws
the toggle formed by the upper end of the bell crank lever 110 and link 113 back
into a straight line, as shown in Fig. 20, and the bell crank lever 119 is raised to
its position shown in Fig. 21, and as soon as the cam 124 engages the outer end 123
of the lever 119, it will, by depressing this end of the lever, throw the clutch out
of engagement with the pulley, the shaft 123 will stop turning, and the machine
will be at rest while the pulley 125 continues to revolve. The form of the arm 116
is shown in Fig. 24, where it is illustrated as being double. The form of the bell
crank lever 119 is shown in Fig. 25.
For the purpose of applying a brake, and stopping the rotation of the shaft 32
simultaneously with the throwing out of the clutch, a ledge 136 is formed on the
clutch 122, and a bar 137 is pivoted to the frame of the machine at 138, see
Fig. 20. The free end of this bar has a shoe 139.
1
140 represents a lever pivoted at 138, and which is located beneath the bar 137. 1
The inner end of this lever is connected to the upper end of the link 113 by means
of a pin 114, see Fig. 21. It will thus be seen that when the toggle is straightened,
the inner ends of the lever 140 and bar 137 will be raised with the lever 119, and
as the cam 124 throws the clutch out of engagement, the ledge 136 on the clutch
comes against the shoe 139 on the bar 137, and thus the shaft 32 is brought to a 2
stop or rest.
141 represents a set screw fitted in the end of the lever 140, and against which
the inner end of the bar 137 rests. By adjusting this set screw, the wear of the
shoe can be compensated for.
In the form of clutch shown in Figs. 3, 27 and 28, the clutch itself is the same 2
as in the form just described, but instead of using the mechanism described for
moving the clutch out of engagement with the pulley, a vertical rod 142, having a
collar 143 is employed, to which the rod or wire 92 is connected. The upper end
of this rod 142 is adapted to fit in the groove 120 of the clutch, as shown in Fig. 27,
or to be moved down out of engagement with the groove, as shown in Fig. 28.
When it is moved down, the spring 126 forces the clutch into engagement with
the pulley 125, and when the lever 90 is released, the rod is pulled up into the
groove by means of a spring 144, (see Fig. 3), the spring connecting the collar 143
to the frame of the machine. When the rod has entered the groove, a cam 145 in
the groove of the clutch comes against the rod, and forces the clutch out of
engagement with the pulley.
In this form of the device, the brake shoe and lever are employed as in the
other form; the shoe being moved by means of a bell-crank lever 147 pivoted to
the frame at 148, one arm of which is connected to the lever of the brake by means
of a link 149, while the other arm is connected to the rod 142 by means of a collar 150,
(see Fig. 27).
Secured to the other end of the cross-head 100 from that at which the rod 104
is connected, is a rod 151 loosely secured to the frame of the machine by boxes or
guides 152, (see Fig. 3). The upper end of this rod 151 is connected by a link
153 to the crank 154 of a shaft or rod 155, supported in suitable brackets or arms
156 on the machine frame, (see Figs. 1, 2 and 3). On the inner end of this
rod 155 is the finger 157 of a dial 158, (see Figs. 2 and 10). It is by this dial
which is directly in front of the operator and in the line of vision, as he is looking
at his work, that the tension of the spring 31 is indicated, and by looking at the
dial the operator is informed of the action of the pump.
The escapement device for shifting the side shaft of the machine, and which is
illustrated in Figs. 1, 3, 4, 28, 41 and 41 will next be described.
This shaft is shifted to vary the feed of the machine upon the last, and to regulate
the length of tack delivered; as, for instance, a long feed and short tack is desired
for the sides of the shoe; a short. feed and long tack is desired for the toe of the
shoe; and a short feed and long tack is desired for the heel of the shoe, and the
different positions of the side shaft so varies the feed mechanism and the tack

page_text: nechanism that the desired feed and length of tack are obtained at the proper
time.
160 represents the side shaft referred to. It is supported at one end by an
extension 161 of the frame, as shown in Fig. 1; at the other end the shaft is
supported by means of a box 164 on the stationary head of the machine, see Fig. 1.
At its inner end the shaft is provided with a crank 165, (see Figs. 3 and 28),
which is connected by a liuk 166 to a wrist-pin 167 on an escapement wheel 168,
(see Figs. 1, 3 and 41^). The escapement wheel is rigidly mounted on a shaft 162.
The shaft is supported in boxes 169, as shown in Fig. 3. On the shaft is a loose
pulley 170, which receives a driving belt 171, from a pulley 172 on the shaft 68.
173 is a fixed disk on the shaft 162, with a washer 174 between it and the pulley.
175 is a spring surrounding the shaft 162 between a fixed collar 176 and a movable
collar 177. 178 represents a washer between the collar 177 and the hub of the
pulley 170. The collar 176 is, as stated, fixed on the shaft 162, but it may be
adjusted thereon by means of a set screw 179, to regulate the tension of the spring
175. The collar 177 is caused to turn with the shaft by means of a pin 180, fitting
in a groove in the shaft which allows the collar to be forced end wise by the spring,
so that the spring will act to force the loose pulley 170 against the fixed disk 173.
When the shaft is not held from turning by the escapement, the friction between
the pulley 170 and the disk 173 is sufficient to revolve the shaft, but when the
shaft is held by the escapement, the pulley 170 runs without turning the shaft.
The escapement wheel 168 has four projections 182, (see Fig. 414), consisting,
preferably of strips 183, set into the face of the wheel, and held in place by set
screws 184, as shown in Figs. 41 and 41, and in front of these projections the
periphery of the wheel is preferably notched, as shown at 185. 186 and 187
represent the arms of the escapement, which are pivoted at 189 to an extension 190
of the frame. The arm 186 has a square end 191, for engaging the projections 182,
and it preferably has an end 192 for entering the notches 185. The end of the
arm 187 is hooked, as shown at 193, for engaging the projections 182, and the face
of the hook is preferably slightly inclined so that when the hook engages the
projections, it will slip over them. 194 represents a bar or extension on the
arms 187 and 186, and which is connected at 195 to one end of a bar 196, the other
end of which is connected at 197, (see Fig. 1), with a finger-piece 198, pivoted
at 199 to the fixed head of the machine. When the arm 186 is in engagement with
the escapement wheel, as shown in Fig. 41, the escapement wheel is held from
turning, and at this time no motion is imparted to the side shaft 160. When the
operator desires to shift the shaft, he presses with his hand against the lower
end 200 of the finger-piece, and moves the arm 186 of the escapement out of
engagement with the escapement wheel. The shaft 162 then commences to turn
the escapement wheel, which imparts its movement to the side shaft 160. As the
arm 186 is moved out of engagement with the escapement wheel, the hook of the
arm 187 is moved into the path of the projections 182, so as to prevent any
possibility of the escapement wheel turning more than one-fourth of a revolution in
case the arm 186 should not come back against the periphery of the escapement
wheel in time to receive the next projection 182. The operator is supposed to
remove his hand from the finger-piece immediately after releasing the escapement,
and the arm 186 is drawn back against the periphery of the escapement wheel by
means of a spring 201, (see Figs. 1 and 41^). The operator thus has the rocking
movement of the side shaft entirely under his control, so that he can shift it to
produce a long feed and short tack, or a short feed and long tack. When the
escapement is in the position shown in Figs. 1 and 414, a long feed and short tack is
obtained for the side of the shoe; as the heel is reached, the operator trips the
escapement, and the escapement wheel is moved to bring the wrist pin vertically
over the shaft of the escapement wheel, at which time a short feed and long tack
will be obtained; as he leaves the heel, the operator trips the escapement again,
and the wrist-pin moves to the opposite side of the shaft of the escapement wheel
to that shown in Fig. 41ª, and a long feed and short tack are obtained for the other

page_text: side of the shoe. Then as the toe is reached, the operator trips the escapement
again, and the wrist-pin moves vertically beneath the shaft, or center of the escape-
ment wheel, and a short feed and long tack are again obtained for the toe, and
then as the toe is left, the escapement is tripped again, bringing the wrist-pin back
to the positions shown in Figs. 1 and 41 for the side of the next shoe to be
lasted.
By providing the notches 185 and the end 192 on the arm 186, the escapement is
held from being turned backward, and consequently the shaft 160 from being shifted,
when the machine, for any reason may be turned backward.
In lasting the heel of a shoe, the leather does not have to be drawn over or acted
upon in any way by the nippers so that the nippers at this time must be inoperative
and they are thrown out of operation by the side shaft 160, through means of a
-collar 160 on the shaft, (see Figs. 38, 39 and 40), which has a projection 160b
adapted to engage a lug 160° on a lever 160 pivoted at 160° to the frame of the
machine, (see Fig. 1), and which is forked at its upper end, (see Fig. 38) to engage
the groove 160 in the hub of the cam 33. This cam has a feather and groove
connection with its shaft 32, and when the side shaft is to give the short feed and
long tack for the heel of the shoe, the projection 160° comes against the lug 160°
and through means of the lever 160 pulls the cam 33 over so that it will not operate
upon the lever 16 and thus the pinchers or nippers are not opened and closed while
the heel is being lasted. As shown in Figs. 33 and 34, the cam 34 projects out
further than the face of the cam 33 and should the nippers be closed on the leather
at the time the heel is reached, and the side shaft is shifted, this projection of the
cam 34 will operate the lever 16 and open the pinchers, which will then remain
open until the cam 33 (carrying the cam 34 with it) is shifted back again by the
shifting again of the side shaft.
The feed device, (by which is meant the mechanism for automatically moving
the last to receive the tacks,) and the manner it is acted upon by the side shaft will
now be described.
205 represents a vertical shaft or rod held and guided by projections or lugs 206,
on the fixed head of the machine, see Fig. 2. On the lower end of this shaft is a
crank head or arm 207, (see Figs. 1 and 10). To the lower end of the head is
secured a finger 208, turned inwardly toward the rear end of the machine, as shown
in Fig. 1, and having a point 209. The finger is secured to the head 207 by means
of a plate 210 and set screws 211 so that it may be adjusted on the head, if desired,
(see Fig. 2).
On the shaft 205 is an upper collar 212, and a lower collar 213, between which
fits one end of a bell crank lever 214, which is pivoted at 215 to the fixed head.
The other end of the bell-crank lever is connected to a rod or bar 216, the inner end
of which straddles the shaft 32, (see Fig. 2). On the shaft 32 is a cam 217, adapted
to engage a projection or roller 218 on the bar 216. As the shaft 32 is turned, the
cam 217 will move the bar 216 end wise, and through means of the bell crank
lever 214 will lift the rod or shaft 205 to raise and lower the finger 208. It is by
this mechanism that the feed finger receives its vertical motion. The finger has
also a reciprocating, horizontal movement, and this movement is imparted, through
means of a cam 219 on the shaft 32, (see Figs. 1 and 2), which engages a roller or
projection 220 on the inner end of a rod or bar 221. The outer end of this bar has
a socket fitting over a lever or arm 222 on the shaft or rod 205, (see Figs. 1, 4
and 10); this lever or arm being secured to the shaft 205 by means of the upper
collar 212, while the lower collar 213 is utilized for securing the head 207 to the
bar or rod.
223 represents a spring connecting a pin 224 on the shaft 205, to the frame of
the machine, (see Fig. 2). The function of this spring is to take up any lost
motion of the cam 219, and connections.
It will be seen that as the shaft 32 revolves, a longitudinal movement will be
imparted to the rod or bar 221, which will in turn impart a rotary movement to
the shaft 205, and this movement of the shaft imparts a reciprocating horizontal

page_text: movement to the point 209 of the finger 208. This reciprocating movement of the
point is what feeds the last in the hands of the operator each time a tack is driven,.
and to get the variable feed heretofore referred to, the side shaft 160 is utilized.
On the side shaft is a bracket 225, best shown in Fig. 56, while its location on the
machine is shown in Figs. 1 and 10.
The cam 225 has a double V-groove 226, in which fits a projection or roller 227
on the lower end of a lever 228, pivoted at 229 to the frame of the machine,.
the lower end of the lever being preferably bifurcated or forked, as shown in.
Fig. 57.
234 represents an arm pivoted at 231 to the lever 228, and connected to the
lever below the pivot by means of a bolt 232 fitting in a slot 233, either in the lever
or in the arm. The lower end of the arm is curved out of line with the lever 228,.
as shown at 234, Fig. 56, and has a slot 235 which receives the rod or bar 221. By
the slot-and-pin connection 232, 233, the lower end of the arm may be shifted'
relatively to the lever 228. By adjusting the side shaft, through means of the
escapement, as heretofore explained, the point 227 of the lever 228 is moved in or
out, through means of the grooves 226 in the bracket 225, and this movement is
imparted to the rod or bar 221, moving it in or out on the lever 222, thus causing
the point 209 of the finger 208 to move a greater or less distance. When a long
feed is desired, the side shaft is shifted to bring the bracket 225 into the position
shown in Fig. 56, thus moving the rod or bar 221 inwardly on the lever 222; then
when a short feed is desired, the side shaft is shifted so that the projection 227 will.
be at one end of the slot 226 in the bracket, thus moving the rod or bar 221
outwardly on the lever 222, and thus the different lengths of feed are acquired by
simply shifting the side shaft 160. The form of the slot 226 in the bracket 225
will give the two short feeds for the toe and heel, while the projection 227 is in the
ends of the slot 226, and will give the two long feeds for the sides of the shoe
when the projection 227 is at the center or middle of the slot 226, and these
adjustments come in the proper order or rotation, by the intermittent turning
of the side shaft, through means of the intermittent quarter movement of the
escapement wheel.
It is sometimes desirable to lengthen or shorten the feed, both for the sides
and for the heel and toe, while the relative distance remains the same, and
this is attained by shifting the arm-234 on the lever 228, through means of the
slot and bolt connection 232, 233; the bolt, of course, being tightened after the
adjustment is made.
To permit the outer end of the rod or bar 221 to be shifted in and out on
the lever 222, a hinged joint is formed in the bar, as shown at 238, (see Fig. 4,).
and to permit of the vertical movement of the outer end of the rod or bar with
the shaft 205, a hinged joint 239 is formed in the bar; these two hinges forming a
universal joint.
The mechanisms just described for imparting the vertical and horizontal
movement to the point 209 of the finger 208, are so disposed and arranged that .
the point describes a movement illustrated in Fig. 58. Supposing the point to be
in its upper position, as shown in Fig. 58, it first descends, as illustrated by the
arrow, then moves back to the position shown in dotted lines at 240, then descends
into the last, then rests a moment until the tack is driven, then moves forward
carrying the last with it, and then ascends again, lifting the leather with it,.
(it being now under the leather,) where it rests until the nippers come down
and grasp the leather, and then the point moves down again, and the operation
continues.
It will be observed that when the point rises, it is between the last tack
which has been driven, and the nippers, and this is important, for the reason that it
holds the edge of the leather up well into position to be grasped by the nippers;
and it holds the leather up much better than it would were it on the other side of
the nippers, or were the nippers between it and the last tack driven.

page_text: The action or movement of the feeder point is illustrated in the diagram views,
Figs. 5 to 9 inclusive, as well as in Fig. 58.
241 represents a guide against which the operator holds the last, subject to its
movement by the feeder point. This guide is secured, as shown in Fig. 1, to the
stationary head of the machine.
The tack mechanism will now be described. 250 and 251 represent the tack
boxes. They are supported by brackets 252 on the stationary head of the machine,
(see Figs. 4 and 10,) and they are turned by belts 253, which pass over pulleys 254
on the shaft 32, and over guide rollers 255. 256 are the raceways extending from
within the boxes, in a downwardly direction to a point near the center of the
machine. The race-ways fit loosely at their upper ends, in the openings in the tack
boxes, and at their lower ends are loosely held against the block 257, by means of
conical pointed screws 258, (see Fig. 44,) which pass through arms 259 secured to
the block 257. The raceways are thus permitted to move slightly when they are
tapped, and lodging of the tacks is guarded against. The raceways in this instance,
as shown in Figs. 14 to 15 are composed each of a solid piece grooved all the
way down, as shown at 260, (see Figs. 14 and 14*,) for the escape of headless tacks,
and grooved part way down, as shown at 261, Figs. 144 and 15 for the passage of
the tacks, while their heads ride along on the upper surface of the race-ways. The
raceways are covered each by a strip 262 resting at its ends on raised parts 263 on
the top edges of the race-ways and held thereon by a strap 264 secured thereto
and to the race-way, (see Fig. 14B). By thus forming the race-ways and providing
the strips 262, the tacks can be easily seen while they are not allowed to be jarred
from the raceways.
The bristles of the brushes 265 are arranged to sweep across the upper ends of
the race-ways within the boxes, as shown in Fig. 11, and the brushes are arranged
so that they pass sidewise over the races. A good action of the brushes in
sweeping the loose tacks from off the upper ends of the race-ways is thus obtained.
The brushes are secured to short shafts 266, journalled in the sides of the boxes,
and outside of the boxes, the shafts are provided with stems 267 having heads 268
for striking and tapping the race-ways, the stems being moved in one direction
by pins 269 on the outer face of the boxes, and in the other direction by springs 270,
(see Figs. 10 and 11).
The construction and operation of the mechanism for receiving the tacks from
the race-ways, and delivering them to the point where they are driven into the last
will now be described.
The mechanism is shown in Figs. 42 to 54 of the drawings.
275 represents a tack carrying plate having a notch 276 into which the tacks
move from the race-ways as the notch in the plate is brought opposite the grooves
in the race-ways. This plate 275 is secured to a V-shaped support 277, secured
to or formed upon the lower end of a pin 278, (see Figs. 49 and 50); the pin fits
in a hole or pertoration 279 in the block 257. The block is secured to the fixed
head of the machine. To the pin 278, above the block 257, is rigidly secured a
shoe 280. The shoe is shown secured to the pin 278 by a cross pin 281. As the
shoe is vibrated from side to side on the pin 278, it oscillates the plate 275 to bring
the notch 276 in position to receive the tacks from the desired race-way.
282 represents a switch tongue pivoted to the shoe 280 at 283, the shoe being
mortised out on its upper face, as shown at 284, to receive the free end of the
switch tongue. The switch tongue is moved or shifted from side to side, to cause
the shoe to be thrown in the desired direction, through means of the side shaft 160,
and the lever 228. This is done through means of a projection or lug 285 on the
lever, (see Fig. 56), which engages an arın 286 loosely mounted on the shaft 160;
the arm having a collar 287 surrounding the shaft, (as shown in Figs. 57 and 62).
The collar 287 has also a downwardly projecting arm 288 connected by a spring 289
to a fixed part of the machine. On the shaft 160 is another collar 290, having a
depending arm 291, connected by a rod 292 to the switch point 282 by means o
5

page_text: a pin 293, fitting in the slot 294, in the shoe 280. The slot permits the pin to
move transversely of the shoe 280, so that the switch tongue can be thrown by the
rod 292, (see Figs. 47 and 49). The collars 287 and 290 are surrounded by a wide,
flat spring 295, the ends of which fit in notches 296 in the arm 288, and also fit in
notches 297, in the arm 291, (see Figs. 56, 57 and 62). As the side shaft is rocked
to bring the pin 227 of the lever 228 to the centre of the cam bracket 255, the
projection 285 of the lever presses against the arm 286, and forces it in the direction
of the arrow, Fig. 56, and at the same time the lever 291 is forced in the direction
of the arrow, through means of the spring 295, and thus the switch point 282 is
drawn over into the position shown in Fig. 47. Then when the rock shaft moves
the pin 227 of the lever 228 to the outer ends of the cam slots 226, the projection 285
leaves the arm 286, and the spring 289 draws the parts back to their normal
position, the switch 282 being now moved to the other side through means of the
pressure of the spg 289 acting on the lever 291, through means of the spring 295.
This latter posit of the arms 286, 288 and 291, and the spring 295, is shown by
full lines in Fig. 2, while the other position of the parts is shown by dotted lines
in this figure.
300 represents a projection, (preferably in the form of a friction roller,) which
is secured to the movable head of the machine, and which is adapted to enter that
part of the groove or mortise marked 284 in Fig. 47 in the upper face of the
shoe 280, when the movable head advances. This projection 300 enters one side
or the other of the switch tongue 282, according to which side of the centre of the
shoe the switch tongue may have been shifted by the side shaft. 160, as explained.
As the projection enters the groove 284 it moves the shoe into the position shown
in Fig. 44, to get a short tack, or if the switch tongue has been shifted so as to
direct the projection into the groove on the other side of the switch tongue, then
the shoe will be moved to the reversed or opposite position to that shown in
Fig. 44, so as to receive a long tack.
To prevent any possibility of the projection 300 striking centrally on the point
of the switch tongue, what is termed a switch controller is employed. (It is shown
in Figs. 18, 47, 49 and 50.) It consists of an arm 301, pulled forwardly by a
spring 302. The arm is pivoted at 303 to the fixed bed of the machine, and it has
an upper end 304 adapted to be engaged by the movable head of the machine, as
shown in Fig. 18. On the upper end of this arm is a projection 305 adapted to
engage a triangular shaped projection 306 on the lower face of the switch
tongue 282. As the movable head advances the projection 305 on the arm 301
comes against the projection 306, on the switch tongue, and throws the switch
tongue away from the centre of the projection or roller 300, should the point of the
switch tongue happen to be on this centre, so that there is no possible danger of
the point of the switch tongue striking the centre of the roller 300. Nothing
is claimed on this device in this application, as it forms no part of the present
improvements.
As the movable head recedes, the projection 300 leaves that part of the cam
groove marked 284 of the shoe, and as it does so it brings the shoe back into line
with the machine, and moves the plate 275 to bring the notch 276 into line with
the centre of the block 257, as shown in Fig. 50. The tack being now suspended
on the plate 275, with its shank fitting in the notch 276, and its head resting on
top of the plate. In the forward end of the block 257 is a half round groove 308,
which, when the shoe is in its central position is opposite the notch 276 in the
plate 275.
309, (see Figs. 52 and 53) represents a pair of pincher like holders located in a
housing 310, the bottom of which is formed by the folder 42; the members of this
holder are pivoted at 311 to the housing 310, and between their inner ends is
located a spring 312, which tends to keep the outer ends of the holders closed. In
the outer ends of the holders is an opening 313, with a conical bottom, (see Fig. 55).
This opening receives the tacks as they fall from the plate 275, and the tack

page_text: driver, at the proper time, enters this opening and drives the tacks from the
holder into the last, the holder opening under the pressure of the driver, and when
the driver recedes the holder closes again under the influence of the spring 312.
The housing 310, with the folder 42 is secured to the movable head of the machine,
as shown in Figs. 63 and 64, through means of a stem 316, upon which the housing
and folder are formed, or to which they are secured, and this stem is secured to
the movable head by means of a clamp 317, which permits of the longitudinal
adjustment of the housing, with the holder and folder when desired.
On the forward end of the housing 310 is a projection 318, preferably formed
upon a plate 318* secured to the housing by means of screws 319, (see Fig. 52).
This projection 318, has a half round opening 320 beneath which is an opening 321
in the plate 318, and in the housing 310. As the movable head recedes the half
round opening 320 in the projection 318 registers with the half round opening in
the block 257, thus forming a complete circle or circular opening into which the
tack falls, and passing through the opening 321 is received by the holder 309.
The tacks thus have continuous, complete opening through which to pass to the
holder.
It has been stated that when the shoe is brought back into line with the machine,
the tacks are supported on the plate 275. Just as the movable head reaches the
limit of its rearward movement, the tacks are dislodged from the plate through
means of an arm 324, (see Figs. 42 and 45,) the normal position of the arm being
shown in Fig. 45, while its inner position is shown in Fig. 42. The lower face of
this arm has a notch 325 to permit the head of the tack to be carried by the
plate 275 under the arm when the arm is in its normal position. The arm fits in
the socket of a head 326, and is pressed downwardly by a spring 327. 328 is a
horizontal extension of the head 326, and which fits in a socket of a bracket 329
secured to the block 257 by bolts 330. 331 is a spring located behind the exten-
sion 328 and which keeps the arm 324 in its outer position, except when it is
forced back against the pressure of the spring.
332 is a lever hinged at 333 to the bracket 329. The lower end of this lever
fits in an opening in the extension 328, as shown clearly in Fig. 42.
334 is an arm
secured to the movable head 2, and which comes against the lever 332, just as the
head reaches the limit of its rearward movement, and forces the arm 324 inwardly,
dislodging the tack from the plate 275, and allowing it to drop into the holder.
Then, when the movable head advances again, the spring 331 forces the arm 324
back to its normal position, to permit another tack to move or be brought beneath
it at the notch 325.
340 represents the pusher, by which is meant the device that pushes the leather
tightly up over the rounded edge of the last, as it is being drawn by the nippers,
and before it is caught by the presser bar. This pusher is well illustrated in
Figs. 18, 42, and 63. It consists of a leather tongue 341, secured to a head 3+2,
held in a bar or rod 343, by means of a set screw 344 fitting in a slot 345 in the
rod or bar. By loosening the set screw 344 the head 342 can be adjusted in or out.
The bar 343 is supported on links 346, pivoted at 347 to the stationary head, the
links being pivoted at 348 to the bar 343. A spring 349 connecting one of the
arms 346 to the stationary head tends to draw the pusher forward until a projec-
tion 350 on one of the arms comes against the bed plate of the stationary head.
The inner arm 346 has a projection 351 provided with a set screw 352, the inner
end of which rests against a pivoted arm 353, which is provided with a friction
roller 354, adapted to be engaged by the movable head 2 as it reaches the limit of
its inward movement. This impact of the head 2, against the roller 354 causes the
pusher to recede a short distance, and as the head begins to advance, and the
leather is drawn by the nippers upwardly and forwardly, the pusher, against which
the last is held by the operator, moves in a forwardly and upwardly direction under
the influence of the spring 349, and forces the leather against the rounded edge
of the last.

page_text: As the movable head advances, it carries with it a tack in the holder 309, and as
the head reaches the limit of its forward movement, the tack is driven through
means of a driver consisting of a pin 360, secured to the lower end of a vertical
rod 361 held and guided in the movable head, as shown in Figs. 18 and 42.
The mechanism by which the driver is automatically operated will now be
described. The mechanism is well shown in Figs. 1, 2, 10 and 18.
361ª represents a lever pivoted at 362 to a standard 363 on the movable head of
the machine. The outer end of this lever is connected by a link 364 to the upper
end of the driver. The inner end of the lever is provided with a friction roller 365,
adapted to be engaged, when the movable head recedes, by a horn 366, on a
bracket 367, secured to the stationary head of the machine. The horn has an
inclined surface 368, against which the roller 365 impinges, to cause the ascent of
the outer end of the lever, and the consequent ascent of the driver, as the movable
head reaches the limit of its rearward movement. The horn has a horizontal
portion 369 against which the roller 365 bears when the movable head is in its
inner or rear position. The driver is provided with a collar 371, on its upper end.
This collar has a projection 372, to receive the upper end of an arm 373, pivoted
at 374 to the movable head 2. 375 is an arm pivoted at 376 to the fixed head 3,
and the lower end of which impinges against a set screw 377, see Fig. 2. By
adjusting the set screw, the inclination of the arm may be changed. 378 represents
an arm pivoted to the fixed head 3, at 379. This arm has a stop 380 for limiting
its movement toward the arm 375. 381 represents a spring connecting the upper
ends of the arms 375 and 378. The tension of this spring may be regulated by
adjusting the screw 377. 382 represents a projection rigidly secured to the
pintle 362, which pivots the lever 361° to the standard 363. The lever 361" is
also rigidly secured to this pintle.
The operation of this part of the improvement is as follows:-As the movable
head recedes and just as it is about to reach the limit of its inward movement, the
roller 365 on the lever 361* comes against the inclination 368 of the horn 366,
thus lifting the driver, as stated. When the driver is thus raised, a projection 384,
on the arm 373 comes against a bracket or projection 385, on the fixed head of
the machine, and forces the upper end of the arm beneath the projection 372 on
the upper end of the driver, as shown in Fig. 18, the arm being held in either
position to which it may be moved by means of a flat friction spring 386, secured
to the standard 363, and bearing with its free end against the side of the arm.
As the movable head advances, the inner end of the lever 361ª is carried from
under the horn 366, and the driver is now suspended by the arm 373. The con-
tinued movement of the head brings the projection 382 against the arm 378, and
When
expands the spring 381, by forcing the arm 378 away from the arm 375.
the movable head has reached the point where the tack is to be driven, the arm 373
comes against an adjustable projection or bracket 387, secured to the fixed head of
the machine, see Fig. 2, and the arm is thus disengaged from the projection 372,
when the driver will be impelled forcibly downward by the spring 381, the force of
which is imparted to the driver through means of the projection 382, and the
lever 361, through means of the connecting pintle 362. Then when the movable
head recedes again, the driver is again raised, as described, and thus the operation
goes on automatically.
388 represents a plug fitting in the socket 389 on the movable head. Beneath
this plug is a spring, as shown in Fig. 18, and the office of the plug is to form a
cushion for the inner end of the lever 361, as it is forced down by coming into
engagement with the horu 366.
390 represents a presser foot which bears upon the upper where it has been
tacked and holds the upper in opposition to the pull of the pinchers, to keep the
tacks from being drawn out of the last by the pinchers. This presser foot is
secured to a hinged lever 391, pivoted at 392 to the fixed head of the machine
and having a roller 393 on its upper end, which is engaged by a projection 394
on the cam 38. No invention is claimed in this device in this application.
