Improvements in Means or Apparatus for "Heeling' or Manu-
facturing the Heel Portions of Boots and Shoes.
A communication from abroad by JAMES WILLSON BROOKS, of Petersham, in
the State of Massachusetts, one of the United States of America, Trustee for
the Kay & Bigelow Heeling Machine Association, of Boston, in the aforesaid
State, Gentleman.
I, Alfred GEORGE BROOKES of 55 & 56 Chancery Lane, in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention to
be as follows:-
:―
This invention has for its object the production of a novel machine by which to
compress heel blanks and to nail them automatically upon the sole of a boot or shoe
while the shoe is held on a last, which last may be of wood.
Prior to this invention it has been customary to mount a shoe to be heeled on a
shoe-holder, and the heel on a heel-support or nail box, and then by a movement
of the shoe towards the heel, or of the heel toward the shoe, the shoe and heel have
been put in firm contact, and the nails have been driven into the heel and into the
sole of the shoe by a gang of drivers operating simultaneously.
In the machine to be herein described, the mechanical parts have been so devised
that the shoe and heel are first put in contact and submitted to a preliminary pressure,
or a pressure sufficient to cause the lifts or layers of leather comprising the heel to
be pinched or laid substantially smooth upon the leather of the shoe, and thereafter,
during a defined portion or fraction of the completion of the relative motions of the
shoe-carrier and heel-support the heel is compressed powerfully to thus hold it
preparatory to diving the nails therein.
This present machine has been devised in such a manner as to automatically
effect substantially uniform compression of the stock or heel material notwith-
standing variations in the height of the various different styles of beels being
operated upon.
To effect this, the maximum separation of the shoe holder and heel support is
always sufficient to accomodate a heel of the greatest height, and the devices
employed to produce a relative change of the position of the shoe-holder and heel
support to effect a closure of the space between them are such as to make their first
or preliminary movement to put the shoe and heel firmly in contact, with a certain
amount of slip or lost-motion, such slip or lost-motion being greater or less as the
heel is lower or higher, but just before the completion of the final closure of the
said space, and while the shoe-holder and heel-support are more or less separated,
that depending upon the thickness of the material then between them and being
subjected to preliminary pressure, the slipping movement of the parts is positively
arrested and thereafter the relative change of movement of the shoe-holder and
heel support is made without slip or lost motion or in other words is made positive
to thus positively compress the heel.
It is thought that the machine herein to be described is the first devised for
attaching heels to boots and shoes so that a defined compression of the heel may be
effected irrespective of its thickness previous to nailing the heel to the sole, and
consequently this invention is not limited to any particular construction of what will
be hereinafter denominated as a slip device and a clutch device, so long as they
co-operate with the various parts of the nailing machine to effect the purposes
herein stated as forming the subject matter of this present invention.
The lasts used in factories and on which shoes are first lasted, are commonly of

page_text: wood and it is a great desideratum to be able to nail the heel onto the sole of the
shoe while the shoe is yet on the wooden last, for by so doing the operation of
removing the shoe from the last for the purpose of applying the heel and then
putting the heeled shoe back on the last for subsequent finishing may he avoided.
The ordinary wooden last cannot, however, safely be used in a power-actuated
heeling machine, for when subjected to the pressure or strain due to the action of
drivers which drive all the nails at one blow, the last soon splits and becomes
worthless.
To obviate this splitting of the lasts and enable them to be used as described, the
nail-driving mechanism has been so devised and improved that the drivers are
actuated in groups or sections about the heel, and in this way the strains are
never greater than the wooden last can bear with safety.
One part of this invention therefore consists in the use in a machine for com-
pressing and attaching heels to boots and shoes, of the following instrumentalities,
viz. a heel-support; a shoe-holder; devices to effect a relative change of
movement of said heel-support and shoe-holder to close the space between them with
a self-adapting pressure to thereby accomodate for the height of a heel, and subject
the heel and shoe to preliminary pressure; and devices to thereafter ensure further
relative closing movements of said parts with a positive pressure to effect a definite
compression of the heel.
Also the use in a heel nailing machine, with a shoe-holder and a heel-support, of
mechanism to move them toward and from each other, said mechanism having as a
co-operating part of it a slip device, and a clutch device, the latter arresting the
slipping of the slip device to enable the heel to be thereafter subjected to positive
compression.
Also in the use in a machine for compressing and attaching heels to boots and
shoes, of the following instrumentalities, viz. :-a nail driving mechanism; a heel
support; a shoe-holder; devices to effect a relative change of movement of said
heel-support and shoe-holder to close the space between them with a self adapting
pressure to thereby accomodate for the height of a heel and subject the heel and
shoe to preliminary pressure, and devices to thereafter ensure further relative
closing movements of said parts with a positive pressure to effect a definite
compression.
Also in a heel nailing machine, the use with a heel-support having a vertical
movement, and a shoe-holder, of an automatically operating slip device, whereby
the movement of the shoe holder may be made substantially in unison with that of
the heel-support as the heel and shoe are being brought together with preliminary
pressure; and a suitable clutch or locking device to arrest the motion of the slip
device and effect a definite positive compression of the heel.
Also in a heel nailing machine, the use with a nail holder or box, a series of
drivers, and independent driver-bars, combined with mechanism adapted to actuate
the drivers in groups or sections, to thus drive the nails in section.

Improvements in Means or Apparatus for "Heeling" or Manu-
facturing the Heel Portions of Boots and Shoes.
A communication by JAMES WILLSON BROOKS, of Petersham, in the State of
Massachusetts, one of the United States of America, Trustee for the Kay
& Bigelow Heeling Machine Association, of Boston, in the aforesaid State,
Gentleman.
I ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane in the County of
London, Chartered Patent Agent 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 has for its object the production of a novel machine by which to
compress heel blanks and to nail them automatically upon the sole of a boot or shoe
while the shoe is held on a last, which last may be of wood.
Prior to this invention it has been customary to mount a shoe to be heeled on a
shoe-holder, and the heel on a heel-support or nail box, and then by a movement of
the shoe towards the heel, or of the heel toward the shoe, the shoe and heel have
been put in firm contact and the nails have been driven into the heel and into the
sole of the shoe by a gang of drivers operating simultaneously.
In the machine to be herein described, the mechanical parts have been so devised
that the shoe and heel are first put in contact and submitted to a preliminary
pressure, or a pressure sufficient to cause the lifts or layers of leather comprising
the heel to be pinched or laid substantially smooth upon the leather of the shoe,
and thereafter, during a defined portion or fraction of the completion of the relative
motions of the shoe-carrier and heel-support the heel is compressed powerfully to
thus hold it preparatory to driving the nails therein.
This present machine has been devised in such manner as to automatically effect
substantially uniform compression of the stock or heel material notwithstanding
variations in the height of the various different styles of heels being operated upon.
To effect this, the maximum separation of the shoe-holder and heel-support is
always sufficient to accomodate a heel of the greatest height, and the devices
employed to produce a relative change of the position of the shoe-holder and heel-
support to effect a closure of the space between them are such as to make their first
or preliminary movement to put the shoe and heel firmly in contact, with a certain
amount of slip or lost motion, such slip or lost-motion being greater or less as the
heel is lower or higher, but just before the completion of the final closure of the
said space, and while the shoe-holder and heel-support are more or less separated,
that depending upon the thickness of the material then between them and being
subjected to preliminary pressure, the slipping movement of the parts is positively
arrested and thereafter the relative change of movement of the shoe-holder and heel-
support is made without slip or lost motion, or in other words, is made positive to
thus positively compress the heel.
It is thought that the machine herein to be described is the first devised for
attaching heels to boots and shoes so that a defined compression of the heel may be
effected irrespective of its thickness previous to nailing the heel to the sole, and
consequently this invention is not limited to any particular construction of what
will be hereinafter denominated as a slip device and a clutch device, so long as
they co-operate with the various parts of the nailing machine to effect the purposes
herein stated as forming the subject matter of this present invention.
The lasts used in factories and on which shoes are first lasted, are commonly of
wood and it is a great desideratum to be able to nail the heel on to the sole of the
shoe while the shoe is yet on the wooden last, for by so doing the operation of
removing the shoe from the last for the purpose of applying the heel and then
putting the heeled shoe back on the last for subsequent finishing may be avoided.

page_text: The ordinary wooden last cannot, however, safely be used in a power-actuated
heeling machine, for when subjected to the pressure or strain due to the action of
drivers which drive all the nails at one blow, the last soon splits and becomes
worthless.
To obviate this splitting of the lasts and enable them to be used as described, the
nail-driving mechanism has been so devised and improved that the drivers are
actuated in groups or sections about the heel, and in this way the strains are never
greater than the wooden last can bear with safety.
One part of this invention therefore consists in the use in a machine for com-
pressing and attaching heels to boots and shoes, of the following instrumentalities,
viz.; a heel-support; a shoe-holder; devices to effect a relative change of move-
ment of said heel-support and shoe-holder to close the space between them with a
self-adapting pressure to thereby accomodate for the height of a heel and subject
the heel and shoe to preliminary pressure; and devices to thereafter ensure further
relative closing movements of said parts with a positive pressure to effect a definite
compression of the heel, substantially as will be described.
Also the use in a heel nailing machine, with a shoe-holder and a heel-support, of
mechanism to move them toward and from each other, said mechanism having as a
coöperating part of it a slip device, and a clutch device, the latter arresting the
slipping of the slip device to enable the heel to be thereafter subjected to positive
compression, substantially as will be described.
Also in the use in a machine for compressing and attaching heels to boots and
shoes, of the following instrumentalities, viz. ;-a nail driving mechanism; a heel-
support; a shoe-holder; devices to effect a relative change of movement of said
heel-support and shoe-holder to close the space between them with a self-adapting
pressure to thereby accomodate for the height of a heel and subject the heel and
shoe to preliminary pressure, and devices to thereafter ensure further relative closing
movements of said parts with a positive pressure to effect a definite compression,
substantially as will be described.
Also in a heel nailing machine, the use with a heel-support having a vertical
movement, and a shoe-holder, of an automatically operating slip device, whereby
the movement of the shoe-holder may be made substantially in unison with that of
the heel-support as the heel and shoe are being brought together with preliminary
pressure; and a suitable clutch or locking device to arrest the motion of the slip
device and effect a definite positive compression of the heel as will be set forth.
Also in a heel nailing machine, the use with a nail-holder or box, a series of
drivers, and independent driver-bars, combined with mechanism adapted to actuate
the drivers in groups or sections, to thus drive the nails in sections, substantially
as will be described.

invention to be understood;

Figs. 8, 9 and 10 are details of a modified form of the invention ;
Fig. 11 is a partial rear end view of the machine shown in Fig. 1 ;
Fig. 12 shows a portion of the toothed gear A' with the clutch device interposed
between its hub or central opening and the cam shaft to be described;

page_text: Figs. 13 to 17 show different views of the devices entering into and forming the
clutch.
A represents the framework; A', a power shaft having its bearings therein and
provided with pinions A³, A', the pinion A3 engaging a toothed gear A, fast on a
cross shaft A, while the pinion A engages a toothed gear B* normally loose on a
shaft B having at its opposite end a weighted crank arm B³ provided with a pin B¹º
on which is a block B which enters a slot in a lever C³, pivotted at its lower end,
the slotted upper end of the lever embracing a projection of a carriage C+ adapted to
be slid back and forth upon a track or guide 3 fixed with relation to the frame-
work.
The cross shaft A' has at one end a pinion A' which engages a toothed gear A³×
normally loose on a cross shaft A°.
In practice each of the toothed gears A³, B' and A³× are rotated continuously
from the power shaft through the pinions described.
Each of the said continuously driven toothed gears has coöperating with it a
clutch device, the said clutches being substantially alike in construction and
operation, so that I need herein specifically describe and illustrate but one of said
clutches, the said clutches being adapted to be operated to effect either the rotation
of a hollow cam shaft B10, or the shaft 13, or the shaft A on which is mounted the
gear Ax, as may be required to effect the proper relative motions of the parts.
The invention herein to be described is applied to a well known form of heel
nailing machine, and I shall not therefore describe particularly the parts except
those having to do with this particular invention.
Referring to Fig. 12, it will be noticed that the hub of the toothed gear A is
chambered at one side to receive loosely a clutch, consisting essentially of a loose
collar C see Fig. 16, having a cam projection Cx, and a series of laterally extending
fingers C, the opposing sides of the fingers being concaved see Fig. 14, so as to
hold between them a series of friction rolls C, the ends of said fingers and rolls
being shown in place inside the gear A' in Fig. 12.
The collar C referred to has at its rear side a circular groove as C³, see Fig. 13
in which are secured two like pins 2, upon each of which is hooked one end of a
like spiral spring 4, the free end of each spiral spring not reaching quite to the
pin 2 which holds the other spiral spring, so that a small space is left, as shown in
Fig. 13 at the free end of each spiral spring, for the reception of a stud as 5
projecting from a flange or collar Co splined upon a hollow shaft or sleeve B
surrounding the shaft Aº.
The sleeve B10 has fixed to it at one side of the said collar C° a hub C7, the
periphery of which, see Fig. 12, has a series of cam faces or inclines, against which
rest the rollers C' carried between the fingers C' of the collar C, the said rollers
being all moved down the said inclines and from biting contact with the inner side
of the chamber in the toothed gear A' whenever the collar C is arrested by a
clutch controlling device, shown as an elbow lever B20, having an arm D, the
springs 4 at such time being compressed, but when the collar C is not so held by
the clutch controlling device, then the springs 4 are free to turn the said collar
about the hub C7, the collar at such time moving the said rollers up the inclines of
the said hubs C7 and causing the rollers C to be engaged between the said hub and
the interior of the chamber in the gear A³, so that the said gear, which is moved
continuously as stated, operates to take the sleeve B10 with it, thus rotating said
sleeve and the cam or eccentric B18 thereon for one rotation or until the projection C*
again meets the controlling device.
The eccentric B18 is surrounded by an eccentric strap on a connecting rod N*,
which is jointed at its front end to the two toggle links D, D¹, the link D' being
pivoted upon a fixed pin, while the link D is pivoted to the lower end of a vertically
sliding rod or stem B.
The rotation of the sleeve D10 consequently affects the raising and lowering at
the proper times of the rod or stem B.

page_text: Ine upper part of the framework has a suitable pivot at 102, upon which is
mounted a walking beam or lever F'.
The front end of this lever has pivoted to it a nut F3 carrying a screw F1 joined
to the upper end of a sliding rod or stem F³, which supports a shoe holder F¹, or a
device having pins 103 adapted to enter a suitable last or device for holding a lasted
shoc.
The rear end of the walking beam has connected to it a rod F.
The devices so far referred to specifically by letter are not herein claimed
because they are and have been used in machines for nailing heels upon shoes.
In this present invention the sleeve B10 has been provided with a cam a adapted
to strike and at the proper times move a lever a' pivoted at a², said lever as
represented in Fig. 1, having at its upper end a pin or projection a', which enters
or engages the outer end of an arm forming part of a clutch device to be
described.
The rod F referred to moves in unison with the shoe holder F¹, and when the
machine is in its normal position the shoe holder and the heel support G are
separated for a distance sufficient to enable the shoe holder to receive upon it a last
or other device holding a lasted shoe and the heel support to receive upon it the
heel of the shoe, whatever may be the height of the latter.
Now to effect the purposes of the invention as herein before stated, it became
necessary for my correspondent to and he devised means which I will now describe,
whereby the relative positions of the shoe holder having the lasted shoe and the
heel support having the heel, may be changed, in order that the sole part of the
heel of the lasted shoe and the heel seat of the heel may be brought in firm contact
with a limited amount of preliminary pressure, to thus effect as it were a sort of
calipering of the material, and this done, the heel or material between the shoe
holder and the heel support is subjected to a uniform definite amount of pressure
imparted by a defined or uniform extent of closure of the space between the shoe
holder and the heel support, and thereby a definite amount of compression is given
to the material of the heel preparatory to driving the nails therein.
The device which enables this movement to be effected has been by me named
a slip device, and in Fig. 1, I have shown one form of slip device which I will now
describe.
The slip device shown in Figs. 1 and 6, consists of a cam-like contrivance e
fast to a shaft e¹ having its bearings in ears of a suitable stand e¹.
The hub of this cam contrivance is surrounded by a collar b' shown separately in
Fig. 74, said collar having a series of fingers or projections between which are held
a series of rollers b².
One part of the stand e² as shown best in Fig. 7, which receives the shaft e',
is chambered as best represented in Fig. 6, to receive the fingered end of the
collar b¹ and the rollers 6, the inner walls of the said chamber having, however, a
series of inclined pockets, in which the said rolls may be moved by or through the
handle, before referred to, attached to the collar ', said handle when moved in
the direction of the arrow Fig. 6, causing the rolls to be put into the narrow ends
of the pockets so as to immediately bite upon the hub of the cam contrivance e
with sufficient force to actually prevent it from further slipping under the descending
movement, in this instance, of the rod F.
In order to insure the proper amount of slipping movement of the device referred
to, and yet keep it under control, I have in this instance of the invention employed
a rack c pivoted at c¹ upon the rod F, it engaging a pinion efast on the shaft e',
and during the relative change of position of the shoe-holder and heel-support, this
rack and pinion, by turning the device e, enables the slipping or yielding movement
to be effective, as when the shoe and heel are being brought together and confined
with a preliminary pressure, and this done, the cam a by or through the lever a¹
moves the arm b of the clutch device described and fixes the device e so that it can
no longer slip, and it is while this slipping or.yielding of the parts is prevented that

page_text: the final change of position to effect the final closure of the space between the shoe-
holder and heel support by the rising of the rod or stem B is effected to definitely
and positively compress the heel preparatory to driving the nails from the heel into
the shoe.
In the form in which I have herein illustrated the invention, it will be understood
that the heel placed upon the heel support underneath the heel-end of the sole of
the lasted shoe on the shoe-holder, will be raised by or through the link N' and
toggle until the heel and sole are brought together and subjected to a preliminary
pressure, and it is during the time that this preliminary pressure is being effected
that the slipping device by its movement, as stated, permits the shoe-holder to rise,
and after the preliminary pressure has been effected,-the slipping being more or
less according to the height of the heel, the device which previously permitted
the slipping of the parts, is positively arrested so that the shoe-holder can no longer
rise, and consequently as the heel support completes its upward throw, the definite
pressure to effect the compression of the heel, is effected.
I have shown the shoe support as the device which has the power applied to it to
effect the relative closure of the space between it and the shoe-holder, yet this
invention is not limited to the application of the power to the said shoe-support, as
it might equally well be applied to the shoe-holder, as it is immaterial which of the
two devices, the shoe-support or the shoe-holder, yields with relation to the other
or slips during the preliminary closure of the space between them, and which is
thereafter positively held or actuated to effect a definite compression of the heel.
As a modification of this feature of the invention, upon referring to Figs. 8, 9,
and 10, it will be seen that the rod F has a projection g which normally rests
against a cam device or contrivance g' forming part of a slip-device, the said cam
device having a hub, as g* which is surrounded by a clutch device 9' consisting
essentially of a ring having a series of fingers with spaces between, substantially as
represented in Fig. 74, in which is a series of rollers g³ see Fig. 9, co-operating
with a series of inclines as o at the inner side of a stand or shell go, the said clutch
device having a handle or projection as 7 which is embraced by a suitable lever,
which I have designated by the letter a¹, as it is the equivalent of the lever
designated by that letter in Fig. 1 and will or may be moved at the proper times
in like manner.
The clutch device shown in Fig. 8 will in practice have connected to it a suitable
spring as 9, one end of which is attached to a strap gº carried around the rear side
of the slip-device and attached to it to keep the slip-device against the projection
on the rod F, thus enabling the slipping action to be effected, as before described,
during the preliminary putting together of the heel and lasted shoe, and this done,
the clutch device is operated to arrest the slipping and enable the final definite
compression of the heel to be effected.
I will now describe another feature of the invention, viz. the nail driving
mechanism.
The slide or carriage C has connected to it a chain f extended over an idle
pulley and about a pulley f loose on the upper end of the rod or stem B.
The pulley shown enlarged in Fig. 2, is provided with a series of pawls f³, one
shown in section Fig. 2, and the others shown in plan view Fig. 4, said pawls
engaging notches at the inner side of a ring h having at its lower end a series of
gear teeth which engage a pinion 2 fast on a short shaft provided at its upper
end with a second pinion which engages a toothed gear h, shown in section in
Fig. 2, and separately in Fig. 5.
This toothed gear revolves loosely about the shank m of the heel support G, said
heel-support being in practice a nail-box, or a device having a series of nail-holes
arranged in proper shape to receive the nails to go into the heel, said holes also
receiving and guiding the nail drivers n.
These nail drivers rest upon sectors n² arranged side by side about the shank m
and within a chamber of a casing m³, upon which rests the heel support G.
Each sector n³ has its underside beveled or inclined, and the upper side of the

page_text: gear or ring his provided with one correspondingly beveled cam 20, so that as the
said ring is rotated the cam surface acts on the cam surfaces of the sectors, and
elevates the sectors in succession during each rotation of the ring, each sector
elevating the drivers, one or more, directly above and resting upon it, said drivers
driving the nails through the heel and into the shoe.
As stated, the cam ring his moved only in one direction, but the chain f for
actuating the pulley is a reciprocating chain, and in consequence of this the
ring must be locked during the movement of the chain in one direction, and to
effect this, the said ring has been provided with a series of ratchet teeth 20 which
are engaged by a spring-pressed detent 21, in this present invention pivoted upon
the head 22 at the upper end of the rod or stem B.
The lower end of the rod F is provided with a shoe p which rests upon the surface
of the slip-device, the shoe taking the wear, the shoe being connected to a movable
block adjustably mounted in the rod F.
My correspondent believing himself to be the first to automatically drive the
heel nails in groups and in succession, this invention is not limited to the employ-
ment only of the sectors, as said sectors constitute but one form of driver bar; nor
is this invention limited to the exact form of device employed for lifting the driving
bars or sectors in succession.
I have shown and described the employment of several different forms of what I
have denominated "slip devices," but this invention is not limited to the employment
of slip devices of the particular forms shown, as any form of mechanical device
which, during a part of the relative change of position of the shoc-holder and heel
support will slip or yield to accomodate variations in height, or vertical thickness
of the heel to be nailed, and thereafter effect for the final closure a positive
movement without slip to accomplish a definite compression of the heel, will come
within the scope of the invention, and such devices may by skilled mechanics be
produced of very different form and appearance, and yet not depart from the
invention.
•
While I have described a novel nail driving mechanism to enable wooden lasts to
be used to advantage, yet it will be understood that the compressing feature applied
to the heel and shoe may be practiced with any usual or suitable form of nail
driving mechanism.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination or arrangement and use of mechanism by which to compress
heel blanks and to nail them automatically upon the sole of a boot or shoe while
the shoe is held on a last substantially as set forth and shewn by the drawings.
2. The arrangement or combination and use in a machine for compressing and
attaching heels to boots and shoes, of the following instrumentalities, viz. ;-a heel-
support; a shoe-holder; devices to effect a relative change of movement of said
heel-support and shoe-holder to close the space between them with a self-adapting
pressure to thereby accomodate for the height of a heel and subject the heel and
shoe to preliminary pressure; and devices to thereafter ensure further relative
closing movements of said parts with a positive pressure to effect a definite
compression of the heel, substantially as shewn and described.
3. The combination or arrangement and use in a heel nailing machine, with a
shoe-holder and heel-support of mechanism to move them toward and from each
other, said mechanism having as a coöperating part of it a slip device, and a clutch
device, the latter arresting the slipping of the slip device to enable the heel to be
thereafter subjected to positive compression, substantially as shewn and described.
4. The construction or combination and the use in a machine for compressing
and attaching heels to boots and shoes, of the following instrumentalities, viz. :-
a nail driving mechanism; a heel-support; a shoe-holder; devices to effect a relative
change of movement of said heel-support and shoe-holder to close the space

page_text: between them with a self-adapting pressure to thereby accomodate for the height of
a heel and subject the heel and shoe to preliminary pressure, and devices to
thereafter en-une further relative closing movements of said parts with a positive
pressure to effect a definite compression, substantially as shewn and described.
5. The combination or arrangement and use in a heel nailing machine, with a
hecl-support having a vertical movement, and a shoe-holder, of an automatically
operating slip device, whereby the movement of the shoe-holder may be made
substantially in unison with that of the heel-support as the heel and shoe are being
brought together with preliminary pressure; and a suitable clutch or locking
device to arrest the motion of the slip device and effect a definite positive
compression of the heel as set forth.
6. In a heel nailing machine, the combination or arrangement and use with a
nail-holder or box, a series of drivers, and independent driver-bars, combined with
mechanisin adapted to actuate the drivers in groups or sections, to thus drive the
nails in section, substantially as shewn and described.
7. In a heeling or heel manufacturing machine for boots and shoes the construction
or arrangement and use of parts cooperating together to effect a defined and
uniform compression of the heel material substantially respective of its thickness
preparatory to nailing the same substantially as and for the purpose herein before
set forth.
