Mechanism for Use in the Attachment of Heels to Boots
or Shoes.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent
Agents, Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of my invention for "IMPROVEMENTS IN NAIL FORMING, DISTRIBUTING
AND DRIVING MECHANISM FOR USE IN THE ATTACHMENT OF HEELS TO BOOTS OR
SHOES to be as follows:-
"
This invention relates to machines for attaching heels to boots and shoes, and
has for its object to provide means whereby the operations of compressing the
heel-blank upon the boot or shoe, making the heel nails, distributing them auto-
matically to a holder, delivering them in a gang or group to a position from which
they are driven automatically, forming holes in the heel blank, automatically
driving the nails through the holes thus formed, and automatically applying the
top-lift and spanking, or spanking alone, are conducted as successive and automatic
operations.
According to the said invention the side frames of the machine are connected by
suitable cross girths, and a bed. This bed supports a jack, which, preferably, is
arranged to slide thereon, and has a vertically movable spindle or post which carries
or supports, at its upper end, the last or work-support. The table also carries a
post upon which a carriage has a vertical movement as hereinafter specified. The
said carriage sustains or supports a templet plate which carries at its forward end
a movable templet block, and which is automatically moved horizontally by a lever
and cam into and out of operative position beneath the awls, drivers, and the heel
support.
The nail-carrier which is moved horizontally into and out of operative position
with the templet and nail-holder by a lever and a cam, has a movable sliding
bottom plate, which is automatically held closed to cover the holes in the nail-
holder plate while it is receiving nails from the nail-holder aud while they are being
carried to a position over the templet block. This bottom plate is automatically

page_text: moved to open the holes in the nail-carrier when the holes therein are brought
into register with the holes in the templet block. The nail-holder has holes having
a similar arrangement to those in the nail-carrier and the templet, and it is adapted
to receive nails which are automatically fed thereto, and to hold them until
discharged into the nail-carrier. It has also an automatic sliding bottom plate
which is automatically opened when the holes in the nail-carrier are brought into
register with the holes in the nail-holder, and is automatically closed, and held
closed, at all other times.
Immediately above the nail-holder is arranged the nail-distributor, which, is a
disc having holes arranged in its edge equi-distant apart, which holes are connected
with the holes in the nail-holder by tubes. The said nail-distributor is adapted to
receive the nails either from a nail-making machine of any sort, kind or description,
or from a nail-distributing or feeding machine; when used in connection with a
nail-making machine it is desirable that the distributor and the holder shall be
made to have a movement, preferably a revolving movement, in relation to the
throat or passage of the machine, through which the nails leave it, in order that
the nails may be delivered, successively to the holes in the distributor.
The distributor and the nail-holder may be connected together by a post and
carried or supported in suitable plates in such a manner as to permit of their being
revolved by a ratchet wheel and lever which carries at its lower end a pawl and is
actuated by the cam, upon the main shaft of the machine for making the nails.
The nails are made singly from wire that is held or supported by a suitable reel.
The nail forming device comprises in substance a wire feed, and nail-pointing and
severing mechanism. The wire-feeding mechanism comprises two feed-rolls adapted
to grasp the wire at certain intervals and carry it a limited distance. One of these
rolls is movable horizontally in relation to the fixed roll, upon the main shaft and
it is this horizontal movement of the said roll that governs the length of the wire
fed. The said roll is positively revolved by the fixed roll by means of a pinion
attached thereto, and is moved into and out of contact with the fixed roll by
means of an oscillating arm which carries a wedge that is brought in contact with
a block and the lower arm of a spring lever. This block, is oscillated by means of
a cam a lever and a bar or rod, connecting the end of the lever with the block.
This bar or rod may be movable horizontally to vary the horizontal position of
the wedge-block in relation to the end of a lever whereby the duration of contact
between the feed roll, and the fixed roll is varied. When the contact is longer it
is obvious more wire is fed, when it is shorter the reverse is the case.
The wire is feed through the feed-way of the machine to a reciprocating cutter
which forms intersecting bevels upon the wire. This cutter is reciprocated across
the feed way by means of a lever and cam upon the main shaft the feed way
ending in a throat.
The wire is pointed and a nail severed at the same time. This is brought about
by feeding the wire past the cutters so that a length sufficient to form a nail shall
always extend downward beyond the line of reciprocation of the cutters and upon
the reciprocation of the cutters a nail is cut off, which either falls through the
throat into one of the holes of the distributor, or is forced therefrom by the next
feeding movement of the wire to feed the length of wire for the next nail into
position.
The nail-making device is operated from a counter shaft by a belt running to a
pulley, and it is set in motion by a cam on the cam-shaft of the heel nailing
machine, and automatically stopped after a sufficient number of nails to fill the
holder have been made.
To attach the heel blank it is necessary to use a gang or group of awls a gang
or group of drivers, and generally, the heel spanker, with or without the top-lift
attaching devices. A block supporting a gang or group of awls is attached to an
arm of a revolving head. Another block holds a gang or group of drivers and is
attached to an arun of the revolving head, and a spanker block carries a top-lift
holding device, also attached to an arm of the cross head.

page_text: The revolving head is mounted on a shaft having bearings in a cross-head which
is reciprocated by rods, and a lower cross-head a pitman and a crank. The revolving
head is automatically turned by means of devices which operate to turn the same a
third of a revolution during the upper part of its vertical movement, and which
hold it locked during the lower part of its vertical movement, so that the awls,
drivers, spanker and top-lift holding devices are successively brought into operative
position automatically, and held locked while they are reciprocated, in order that
they may properly register with the holes in the templet and nail-holder, and with
the work.
A pulley-shaft carries a pulley which forms the movable member of a clutch.
The said pulley is moved into contact with the fixed portion of the clutch, by
means of a treadle, and a wedge which is lifted by a treadle against a second wedge
at the lower end of a lever which is pivotted and which above the pivot point holds
the hub of the said pulley. After the pulley is moved by the treadle in contact
with the fixed member of the clutch, it is held in contact therewith by an edge
cam and lever, the upper end of which bears against the cam until a notch in the
face of the cam allows a spring to disengage the pulley from the fixed member of
the clutch by throwing the lower end of the lever outward, and the upper end of
the lever inward, the anti-friction roll thereon entering the notch in the cam disc.
This cam disc is upon a cam shaft, and makes one revolution to every three of
the pulley shaft, so that the machine after it is started makes three reciprocations
and stops. The pulley shaft communicates its power by pinions to gear wheels
upon the crank shaft, and also by a gear wheel to the cam shaft.
To further illustrate the construction and operation of the machine I will suppose
that the operator is about to attach a heel blank. He first places the shoe upon
the work support, moves it into position, and properly places the heel blank upon
the sole. He then, by means of a hand lever which is connected with the carriage
or table by a link, moves the table or carriage downward against the pressure of a
spring and brings the templet block upon the upper surface of the heel blauk. He
then starts the machine.
The awls are then brought into position and caused to enter the holes in the
templet-plate and form holes in the heel-blank, and the awl block comes in contact
with the upper surface of the templet block, and moves it forcibly downward on
the heel-blank and compresses it, moving at the same time, the table and all that it
supports, the latter being automatically locked in this depressed position by a latch
or locking device. The awls are then lifted, the nail-holder advances and delivers
its nails to the templet in a gang or group. Meanwhile the drivers have been
brought automatically into position and reciprocated, entering the holes in the nail-
carrier and templet plates, and driving the nails therefrom through the holes, so
that their points are clinched on the iron surface of the heel support. If the heel
is to be blind-nailed then the drivers are made shorter than the holes in the nail
carrier and templet, so that the buts of the nails shall be left projecting from the
heel blank a sufficient distance to receive the top lift which is spanked thereon.
The latch or lock is then automatically unlatched or unlocked by a cam upon
a countershaft, and a lever and an unlatching arm, and a spring lifts the carriage,
templet, and nail holder from the work. Immediately after being lifted they are
both withdrawn from over the heel blank, and the nail carrier is moved under the
nail holder, automatically moving the sliding plate, thereby uncovering the holes
therein, and it immediately receives a gang or group of nails which has previously
been deposited therein, and after receiving such load of nails immediately moves
forward a distance to allow the sliding plate to automatically close the holes in
the nail-holder. This distance is about one fourth of an inch. The nail making
machine is set in operation by a cam on the main shaft, which operates a push rod,
lifting it upward and causing it to lift an arm which allows a spring to draw the
lever, carrying the pulley into contact with the fixed member of the clutch upon
the main shaft.

page_text: The nail making machine being thus started proceeds to immediately make
enough nails to fill the nail holder. The holes of the nail distributor being
advanced sufficiently to receive the nail from the throat of the machine, they are
distributed from the distributor by the tubes to the nail-holder in succession, the
nail-holder holding the nails until they are discharged, as above specified.
When all the holes in the nail-holder are filled, the nail making device is auto-
matically stopped by means of the wedge-block on the revolving distributor, which
comes in contact with the end of the arm (which has been permitted to return or
fall by the downward movement of the push rod) and moves it outward, moving the
lever and causing it to push a friction pad, against the fixed member of the clutch
while at the same time it moves the driven pulley out of engagement therewith,
and the machine immediately comes to rest.
While the nail-carrier is receiving its load of nails, and the nails are being made,
the spanker having a top-lift holding device thereon, if the heel is to be blind
nailed, and having a top lift secured therein, is being brought into position and
reciprocated, and the heel spanked, or a top-lift spanked on, so that while the
operation of feeding the gang or group of nails from the nail-holder to the nail-
carrier is proceeding, and the nails are being made for the next load, the spanker is
being operated. The spanker finishes its operation first, and the nail-making
devico continues its operation until the nails are all made, and it generally runs
from two to five or six seconds after the spanker has come to rest.
When the machine stops the templet plate is in position for nailing the next
heel.

Improvements in Nail Forming, Distributing, and Driving
Mechanism for Use in the Attachment of Heels to Boots
or Shoes.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to machines for attaching heels to boots and shoes and
has for its object to provide means whereby the operations of compressing the
heel-blank upon the boot or shoe, making the beel nails, distributing them
automatically to a holder, delivering them in a gang or group to a position from
which they are driven automatically, forming holes in the heel blank, auto-
matically driving the nails through the holes thus formed, and automatically
applying the top-lift and spanking, or spanking alone, are conducted successively
and automatically.
In the accompanying drawings

the features of this invention.
Figure 2 is a rear elevation of said machine.
Figure 3 is a longitudinal vertical central section of the machine some parts
being shown in elevation.
Figure 4 is a vertical section drawn to an enlarged scale, of a portion of the
mechanism for automatically revolving or turning the revolving head hereinafter
described.

Figure 6 is a view representing in elevation a portion of the table or carriage
latching or unlatching mechanism hereinafter referred to.
Figure 7 is a vertical section through the driving and driven members of a
clutch hereinafter described representing the shipping and unshipping mechanism.
Figures 8, 9 and 10 illustrate parts of the nail-making devices.
A, A¹ are the side frames of the machine. They are connected by suitable
cross girths and a bed a. This bed supports the jack B, which preferably is
arranged to slide thereon, and has a vertically movable spindle or post b which
carries or supports at its upper end the last or work support. The table also
carries the post C, upon which the carriage c has a vertical movement as herein-
after specified. This carriage sustains or supports the templet plate c¹ which
carries at its forward end the movable templet block c², and is automatically
moved horizontally by the lever c³ and cam c, into and out of operative position
beneath the awls, drivers, and their heel supports.
D is the nail carrier, which is moved horizontally into and out of operativo
position with the templet and nail holder E, by the lever d pivotted at d', and
the cam d². The nail carrier has a movable sliding bottom "plate d³ "which is

page_text: automatically held closed to cover the holes in the nail holder plate while it is
receiving nails from the nail holder and while they are being carried to a position
over the templet c². This plate is automatically moved to open the holes in the
nail carrier when the holes therein are brought into register with the holes in the
templet block. The nail holder E has holes having a similar arrangement to those
in the nail-carrier and the templet, and is adapted to receive nails which are
automatically. fed thereto, and to hold them until discharged into the nail
carrier D. It has also an automatic sliding bottom plate e which is automatically
opened when the holes in the nail carrier are brought into register with the holes
in the nail-holder, and is automatically closed, and held closed at all other times.
Immediately above the nail-holder is arranged the nail distributer e¹ which is a
disc having holes arranged in its edge equi-distant apart; which holes are
connected with the holes in the nail holder E by tubes e². This said nail
distributor is adapted to receive the nails either from a nail making machine of
any sort, kind or description, or from a nail distributing or feeding machine. In
the drawings it is shown as adapted to receive nails made by a nail' making
machine, and when used in connection with such a machine it is desirable that the
distributor and the holder shall be made to have a movement, preferably a
revolving movement, in relation to the throat or passage of the machine through
which the nails leave it, in order that the nails may be delivered successively to
the holes in the distributor. In the drawings the distributor e and the nail
holder E are represented as connected together by the post e³, and carried or
supported in suitable plates in such a manner as to permit of their being revolved
by the ratchet wheel and the lever e pivotted at e and carrying at its lower
end a pawl e, and actuated by the came upon the main shaft e" of the machine
for making the nails.
The nails are made singly from wire that is held or supported by a suitable reel
(not shown). This nail forming device comprises in substance a wire feed and a
nail pointing and severing mechanism. The wire feeding mechanism comprises
two feed-rolls adapted to grasp the wire at certain intervals and carry it a limited
distance. One roll f only is shown. This roll is movable horizontally in relation
to the fixed roll, upon the main shaft e and it is this horizontal movement of the
roll that governs the length of the wire fed. The roll f is positively revolved by
the fixed roll by means of a pinion attached thereto, and is moved into and out of
contact with the fixed roll by means of the oscillating arm, which carries a wedge f¹
that is brought in contact with the block f³, and the lower arm of the spring
lever f. This block f¹ is oscillated by means of a cam f', a lever f³ and a bar or
rod f connecting the end of the lever with the wedge block f'. This bar or rod
may be movable horizontally to vary the horizontal position of the wedge-block in
relation to the end of the lever f³ whereby the duration of contact between the
feed roll fand the fixed roll is varied. When the contact is longer it is obvious
more wire is fed, and when it is shorter the reverse is the case.
1
The wire is fed through the feed-way of the machine (not shown) to a
reciprocating cutter which forms intersecting bevels upon the wire. This cutter is
reciprocated across the feed way by means of the lever g pivotted at g', and the
cam 92 upon the main shaft e; the feed way is straight terminating in the
throat h of the machine, and the wire is pointed and a nail severed at the same
time. This is brought about by feeding the wire past the cutters so that a length
sufficient to form a nail shall always extend downward beyond the line of
reciprocation of the cutters, and upon the reciprocation of the cutters a nail is cut
off, which either falls through the throat into one of the holes of the distributor,
or is forced therefrom by the next feeding movement of the wire to feed the
length of wire for the next nail into position.
The nail-making device is operated from a counter-shaft by a belt running to
the pulley h¹ and it is set in motion by a cam on the cam shaft h2 cf the heel
nailing machine, and automatically stopped after a sufficient number of nails to
fill the holder have been made, as hereinafter indicated,

page_text: To attach the heel blank it is necessary to use a gang or group of awls, a gang
or group of drivers, and generally, the heel spanker with or without the top-lift
attaching devices. In the drawing I have represented these devices, K. being a
block supporting a gang or group of awls attached to the arm of the revolving
head K¹, K² a block holding a gang or group of drivers attached to an arm of the
revolving head K¹; and K³ a spanker block carrying a top lift holding device, also
attached to an arm of the cross-head shown in Figure 2.
The revolving head is mounted on the shaft Khaving bearings in the cross-
head K which is reciprocated by the rods ², lower cross-head ³, pitman /^ and
crank. The revolving head is automatically turned by means of devices which
operate to turn the same a third of a revolution during the upper part of its
vertical movement, and which hold it locked during the lower part of its vertical
movement, so that the awls, drivers, spanker and top lift holding devices are
successively brought into operative position automatically, and held locked while
they are reciprocated, in order that they may properly register with the holes in
the templet and nail-holder, and with the work.
M is the pulley shaft, m the pulley which forms the movable member of a clutch,
m¹ being the other member. The pulley m is moved into contact with the fixed
portion m of the clutch, by means of a treadle m³, and a wedge m³ which is lifted
by the treadle against the wedge m' at the lower end of the lever m³, which is
pivotted at me and which above the pivot point lays hold of the hub m² of the
pulley m. After the pulley is moved by the treadle in contact with the fixed
member m of the clutch, it is held in contact therewith by the edge-cam m³, and
lever m³ the upper end of which bears against the cam until a notch in the face of
the cam allows a spring to disengage the pulley from the fixed member of the
clutch by throwing the lower end of the lever outward, and the upper end of the
lever inward, the antifriction roll thereon entering the notch in the cam disc.
This cam disc is upon the cam shaft h and makes one revolution to every three
of the shaft M so that the machine after it is started makes three reciprocations
and stops. The pulley shaft communicates its power by pinions to gear wheels
upon the crank shaft and also by an intermediate shaft M' and suitable con-
necting gearing with the cam-shaft h².
To further illustrate the construction and operation of the machine I will suppose
that the operator is about to attach a heel blank. He first places the shoe upon
the work support, moves it into position and properly places the heel blank upon
the sole. He then, by means of the hand lever N, which is connected with the
carriage or table c by a link, shewn in dotted lines in Figure 3, and in elevation in
Figure 6 moves the table or carriage downward against the pressure of the spring n,
and brings the templet block upon the upper surface of the heel blank. He then
starts the machine.
The awls are then brought into position and caused to enter the holes in the
templet plate, and form holes in the heel-blank, and the awl block comes in contact
with the upper surface of the templet block, and moves it forcibly downward on
the heel-blank and compresses it, moving at the same time the table c, and all that
it supports, the latter being automatically locked in this depressed position by a
latch or locking device represented in Figures 2 and 6. The awls are then lifted,
the nail-holder advances and delivers its nails to the templet in a gang or group.
Meanwhile the drivers have been brought automatically into position and recipro-
cated, entering the holes in the nail-carrier and templet-plates, and driving the
nails therefrom through the holes, so that their points are clinched on the iron
surface of the heel supports. If the heel is to be blind-nailed then the drivers are
made shorter than the holes in the nail-carrier and templet, so that the butts of the
nails shall be left projecting from the heel blank a sufficient distance to receive the
top-lift which is spanked thereon. The latch or lock is then automatically
unlatched or unlocked by the cam O, upon the cam-shaft h³ the lever o pivotted
at O and the arm 02 for disengaging the latch Os automatically at stated
intervals; and the spring. m. lifts, the carriage, templet. and nail-holder from the

page_text: work. Immediately after being lifted they are both withdrawn from over the
heel-blank, and the nail carrier is moved under the nail-holder, automatically
moving the plate e thereby uncovering the holes therein, and it immediately
receives a gang or group of nails which has previously been deposited therein, and
after receiving such load of nails immediately moves forward a distance to allow
the sliding plate e to automatically close the holes in the nail-holder. This distance
is about one fourth of an inch. The nail-making machine is set in operation by the
cam P on the cam shaft h which cam operates the push-rod p, lifting it upward
and causing it to lift the arm p', which allows the spring på to draw the lever p³,
carrying the pulley h¹ in contact with the fixed member of the clutch upon the
shaft e".
The nail making machine being thus started proceeds to immediately make
enough nails to fill the nail holder. The holes of the nail-distributor being
advanced sufficiently to receive the nails from the throat h of the machine, they
are distributed from the distributor by the tubes to the nail-bolder in succession,
the nail-holder holding the nails until they are discharged, as above specified.
When all the holes in the nail-holder are filled, the nail making device is
automatically stopped by means of a block on the revolving distributor, which
comes in contact with the end of the arm p' (which has been permitted to return
or fall by the downward movement of the push rod p) and moves it outward
moving the lever p, and causing it to push the friction-pad p³ against the fixed
member of the clutch, while at the same time it moves the driven pulley out of
engagement therewith, and the machine immediately comes to rest.
While the nail-carrier is receiving its load of nails, and the nails are being made,
the spanker having a top-lift holding device thereon, if the heel is to be blind
nailed, and having a top-lift secured therein, is being brought into position and
reciprocated, and the heel spanked, or a top-lift spanked on, so that while the
operation of feeding the gang or group of nails from the nail-holder to the nail-
carrier is proceeding, and the nails are being made for the next load, the spanker is
being operated. The spanker finishes its operation first, and the nail making
device continues its operation until the nails are all made, and it generally runs
from two to five or six seconds after the spanker has come to rest.
When the machine stops, the templet plate is in position for nailing the next
heel.
The mechanism for revolving or turning the head carrying the awls, driver, and
spanker automatically, comprises a plate V, permanently attached to the shaft of
the revolving head, and having projecting therefrom the cam pins v, v², v² (see
Figures 4 and 5). These cam pins project from this plate, and are arranged, as the
cross-head supporting the revolving head is reciprocated, to be alternately or
successively brought in contact first with the surface 3 of the locking pawl v³,
fastened to the cross-plate 2, (which movement causes the locking pawl to be
moved outward and then to close behind the cam-pin) and then to come in contact
with the guiding surface 5 of the shifting plate v and the guiding surface v²,
whereby upon the downward movement of the cross-head it is caused to take a
lateral movement until it reaches the straight guiding passage v³ formed by the
projections, when its course is vertical. This lateral movement causes the
head to be partly turned or revolved, and the straight passage holds the head
from being turned or revolved during the lower part of the reciprocation of the
cross-head. Upon the upward part of the reciprocation the pin moves upward to
the passage, and strikes the guiding surface of the shifting block v6, and
riding laterally thereon the head is further revolved or turned during the upper
part of the upward movement of the cross-head.
Meanwhile another cam-pin has come in contact with the surface 12 of the
pawl 3, and the operation proceeds as before. The shifting block ve is moved
laterally by the cam-pin striking the surface v³, and is returned to its original
position after the cam-pin has entered the recess 8, by the cam v12 attached to the
cross-head to reciprocate with it (See Figure 1) and into which the cam pin v¹³

page_text: attached to the shifting plate enters.
The pawl is automatically returned by
the spring latch to its normal position after having been moved out of contact with
the cam-pin thereof by a spring v1.
The shifting block 6 is attached to the plate v by the pins or studs which pass
through slots therein, which permit the lateral movement of the block on the
studs. This mechanism affords a very simple and very effective device for auto-
matically turning or revolving the head during a portion of the reciprocation of
the cross-head and locking it and holding it locked during the remainder of said
reciprocation.
I would say that any machine organized or adapted to make nails and deliver
them through a throat or passage in regular succession, or to assort nails and
deliver them one by one through a throat or passage in regular succession may be
used in connection with the distributor herein described for providing it with nails
or fastenings. I would further state that I do not confine myself to the preciso
details of construction herein described, but may use any mechanical equivalents
therefor.
