Improvements in Nailing Machines chiefly designed for use in the
Manufacture of Boots and Shoes.
I, LOUIS HENRY GODDU, of Winchester, Massachusetts, United States of America,
Mechanic, 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 nailing machines, such as are employed in the manufac-
ture of boots and shoes, and is hereinshown as embodied in a mailing machine in which
the nails are cut from a wire or metal strip of the desired or proper shape in cross
section and driven into the work.
The invention has for its object to provide a machine of the class described, which
is simple, highly efficient, durable and of a minimum number of parts, and one which
requires a minimum expenditure of money for maintenance at the desired or required
standard.
In accordance with this invention, the wire from which the nails are formed or cut,
is carried by a guide which is movable with relation to a throat, which is itself fixed
or stationary with relation to a driver by which the nails may be driven into the
work.
The driver referred to, may and preferably will have two functions, one function
being that of an awl to prick the heel or other work and form a small hole for the
entrance of the slug or nail, and the other function being that of a driver proper by
which the nail or slug may be driven into the said hole. This double function inay
be imparted to the driver in a manner as will be described.
The machine is further provided with a novel feed mechanism, by which the nails
cut from the wire may be of the same or predetermined length, or they may be of a
variable length, so as to adapt them for the particular work required.
The machine also embodies a novel construction of wire cutting mechanism, and is
also provided with a novel work support, and work feed, as will be described. The
machine further embodies a novel starting and stopping mechanisin as will be
described. Another feature of this invention consists in a novel construction by which
the work support or horn is automatically lowered a positive distance after the nail is
driven into the stock.
The machine is further adapted to be provided with a novel construction of work
support or horn by which the work, such as the outer sole of a boot or shoe, may be
fed so that the nails driven therein will form any desired design, which particular
work is technically known as quilting.

The operating parts of the machine hereinshown as embodying this invention, are
supported by a suitable framework, which, as hereinshown, comprises essentially a
base A (see Fig. 3), a hollow post or upright A' secured to or forming part of the base A,
and a head A2 resting on the post or upright A¹ and secured thereto, as hereinshown
by bolts A'.
The head A supports or carries the main operative parts, which, in the present
instance, include a stationary throat or guide for the nail or slug, a feed mechanism
for the wire to be formed into nails or slugs movable with relation to the said throat,
a cutting mechanism which operates to sever a portion of the wire after it has been
fed the desired amount into the said stationary throat and thereby form the nail or
slug, a driver in line with the said throat and by which the nail or slug is driven into
the heel or other stock, and mechanisms by which these operative parts are actuated as
will be described.
The wire feed mechanism referred to, may and preferably will be made as herein-
shown and consists essentially of two members, one of which is movable bodily with
relation to the other. The movable member is made as hereinshown in the form of a
rotatable disk or wheel a, preferably provided with a milled or other biting or gripping
periphery (see Figs. 2, 14, 15, and 21), and the other or fixed member being shown as
a block a¹, secured to a movable carrier for the wire-feed mechanism and hereinshown
as a lever a, having its pivot pin or stud a' (see Figure 15) supported in a bearing in
the front portion of the head A². The feed wheel or disk a is loosely mounted on a
sleeve a supported by the lever a³ (see Figs. 21 and 22), through which the said
sleeve extends and is frictionally secured thereto as hereinshown by a set screw 2",
extended through a split portion of the said lever. The sleeve a³ forms a bearing for a
rock-shaft a, which is provided at its front end, as hereinshown, with an arm a carrying
a pawl as, loosely mounted on said arm and co-operating with the teeth of a ratchet
wheel or disk a³, hereinshown as integral with the feed wheel or disk
the said pawl
being kept in engagement with the said teeth by a suitable spring a⁰ (see Fig. 14).
The feed wheel a is bodily movable toward and from its co-operating member a¹,

page_text: and this bodily movement may and preferably will be accomplished by means of an
eccentric a2 on the sleeve a³, the said eccentric turning within the lever a³ as clearly
shown in Figs. 21 and 22. The sleeve as may be turned as hereinshown, by means
of an arm 3 fastened to the said sleeve, it being shown in Fig. 2, as clamped thereon
by a set screw a¹. The rotation of the feed wheel, as by means of the pawl a", will
be hereinafter more fully explained. The lever a³ constitutes a movable carrier for
the wire feed mechanism, and it also preferably constitutes a like carrier for a guide
for the wire, after the said wire has passed the feed mechanism.
The wire guide referred to, may and preferably will be made as hereinshown, and consists
of a slot, channel or passage a (see Fig. 14) in a metal piece or block a, secured to
the lever as as by a set screw a", the said block also preferably constituting a holder
for a cutting tool or knife a¹s, which is extended as hereinshown, substantially at right
angles to the direction of the passage a15, and is adjustably clamped between the
holder al and the lever a³.
The slot or passage a' is made in the block 6, so that it is closed at its sides and
open only at its ends, whereby the wire a inserted through the said slot is positively
moved with the guide block a¹. The guide block and holder a¹ is provided as
hereinshown (see Fig. 14) with a projecting portion or nose a¹, having a substantially
vertical guideway or passage al forming a continuation of the guideway a", which,
as hereinshown, is inclined (see Fig. 14), the substantially vertical guideway being
in line with a passage 20 in a throat a2i (Fig. 15) which is firmly inserted into an
opening in a throat plate 22 secured to the head A2 as by a screw a23, the said
throat being detachably fastened in the said plate as hereinshown by a set screw a*
(see Fig. 2).
The throat a may and, in the present instance, is, made longer than the thickness
of its plate 22, and may be secured to the said plate so that its lower end is flush or sub-
stantially flush with the lower surface of the said plate, to thereby leave a smooth
surface against which the work may bear, the upper end of the throat being
preferably extended above the said plate, as hereinshown (see Figs. 14 and 15).
The cutter a being carried by the movable lever a³ as described, constitutes a
movable cutter, and co-operates as herein shown, with a stationary or fixed cutter a 25
(see Figs. 1 and 14) secured in a holder, shown as a block or piece a fastened as by
a set screw a, to a block or piece a28, secured to or forming part of the head A², it
being represented in the present instance, as fastened to the head A2 by a countersunk
screw 30 (see Fig. 14). The cutters a, a, are oppositely beveled as hereinshown,
(see Fig. 14), so that when they act upon the wire, a substantially V-shaped point
may be formed on the end of the wire left uncut, while a flat or smooth surface may
be formed on the cut portion or nail.
The cutter holder a may and preferably will be formed, as hereinshown, with an
offset upper portion a³ extended beyond a vertical line through the center of the
throat a, and provided with a substantially vertical passage a³ (see Fig. 16)
constiting a guideway for a tool a33, preferably having, as in the present instance,
the double function of an awl and a driver, but which, for sake of simplicity, will
be hereinafter referred to as the driver.
The driver a³ is designed in practice to pass through the guideway a³ into the
throat a, and to enable this to be accomplished in the construction of the machine
herein shown, the wire guideway is made movable with relation to the throat, which
is itself stationary or fixed with relation to the driver.
The movements of the wire guide and of the driver will be hereinafter more
fully explained.
The cutters 18, a² may be removed from their holders or adjusted therein
The driver a³ is secured to a
by loosening the clamping nuts a, .
reciprocating bar or carrier b, which may be accomplished as shown in Figs. 1 and 15,
by means of a clamping block b¹ secured to the bar b by a set screw b*.
The driver bar or carrier b may be provided as represented. in Figs. 1 and 2, with
side ribs b, b, which enter suitable guideways in a cap, plate or front piece b'
detachably fastened to the head A² as by the screws 6º, 67, 68,

page_text: The wire feed mechanisın, the inovable member of the wire cutting mechanism,
and the driver, are operated by suitable cams, which, in the present instance,
are shown as formed on one disk B (see Fig. 13), fast upon the main shaft b
supported in suitable bearings in the head A2. The disk B is provided on its
rear face with an inclined projection 6" (see Fig. 10), which co-operates with
the
and is adapted to engage a crank or arm 612 (see Figs. 7 and 10), fast on
shaft as shown in Fig. 21, the said arm at its upper end being provided as
hereinshown, with an antifriction roller 613, mounted upon a stud or pin 614 carried
by the said arm, the said roller normally projecting into the path of movement of
the cam 610, so that when the disk B is rotated, as in the direction indicated by the
arrow 20, Figure 10, the cam 610 will strike the roller 613 and depress the end of the
lever 612 so as to rock the shaft a in such a direction as will carry the pawl as, from
what may be regarded as its normal position shown in Fig. 14, back over the teeth
of the ratchet wheel a", the arm a carrying the said pawl, moving in the direction
indicated by the arrow 21, Fig. 14.
The pawl-carrying arm a is moved in the direction indicated by the arrow 21, as
long as the cam 610 remains in engagement with the roller 613, and as soon as the
said cam, in the rotation of the disk B in the direction indicated by the arrow 20,
passes off from or out of engagement with the roller 6, the arm b12 is returned to
its normal position, as hereinshown, by means of the spring 16, having one end
fastened to a stationary part of the machine and its other end fastened to the crank
or arm 612. The return movement of the arm b12 by the spring 610, rocks the shaft a
in the opposite direction, and the pawl being in engagement with a tooth of the
ratchet wheel a, carries the said wheel in a direction opposite to that indicated by
the arrow 21, Fig. 14, which rotary movement of the ratchet wheel effects a like
movement of the feed wheel «, and thereby moves or feeds the wire in the
direction indicated by the arrow 22, Fig. 14. This feed movement of the wire is
continued until the shaft a is arrested in its rocking movement in the direction
opposite to that indicated by the arrow 21, and the said rock-shaft may be arrested
in its return movement at any desired point, by means of an adjustable stop,
hereinshown as a set screw 6" inserted through the arm 61 of the lever 612 and
adapted to strike or abut against the framework or head 2 of the machine, as clearly
shown in Fig. 10.
The set screw 618 is employed when it is desired that a predetermined length of
wire should be fed at each operation of the wire feed mechanisın, so that all the nails
may be driven of uniform length, as when the nails are driven into the top-lift of
the heel, but when it is desired to drive the nails into work varying in thickness, as
for instance, into the shank as well as into the heel, a device or attachment is pro-
vided, which is automatically positioned with relation to the lever 612 according to the
thickness of the work into which the particular nails are being driven. This
attachment will be more specifically described hereinafter.
The disk B is provided on its periphery with suitable cam surfaces to effect the
proper positioning of the movable wire guide a with relation to the stationary
throat 21, so that the said guide may be brought in proper position with relation
to the throat, to direct the free end of the wire into the throat, when the feed
mechanism above described, is operated. The particular portion or cam on the
surface of the disk B, which effects the proper positioning of the wire guide a¹, is
represented in Fig. 13 between the points 50-51. The disk B is further provided
on its periphery with a cam portion or surface between the points 52, 53, by which
the movable cutter and its holder are carried or forced across a plane in a vertical line
with the throat, so as to sever the portion of the wire in the throat from the length
of the wire carried by the guide, and thereby form a nail or slug having a flat or
smooth head or upper surface, and at the same time, provide the free end of the wire
carried by the guide a with a substantially V-shaped point. The disk B from the
point 53 returns back to its normal circle or size, so as to permit of the return
movement of the movable carrier or lever a³, which return movement may and

page_text: preferably will be effected as hereinshown, by a spring 60 (see Figs. 2 and 10), one end of
the said spring being fastened to the head A2 and the other end to the lever ..
The disk B is provided on its front face with a cain groove 6, into which projects
a stud or roller 21 carried by the driver bar b, and represented in Figs. 1 and 13, by;
dotted lines.
The cam groove 620 is designed in the present instance, to effect two reciprocations
or movements of the driver bar b and its attached driver a, during one complete
cycle of the cam disk B, the first of which reciprocations is to prick the leather or
other material, and form a small hole for the reception of the point of the nail or
slug, in which it is properly centred and positioned, and which nail or slug is driven
into the stock or work by the second reciprocation of the driver bar and its attached
driver. The first movement or reciprocation of the driver bar may be effected, as
hereinshown, by the portion of the cam groove between the points 60, 61 (see
Fig. 13), and the second reciprocation may be effected by the portion of the cam
groove from the point. 62 to the point 60. The downward movement of the first
reciprocation is effected while the portion of the cam from the point 60 to the point
65 is passing by the stud or roller bat (see Fig. 23), and from the point 65 to the
point 61, the return movement of the first reciprocation is taking place. While the
cam is travelling from the point 61 to the point 62, the driver bar remains at rest,
as the stud or roller is on a true circle, but when the point 62 of the cam meets
the roller 21, the said roller and its driver bar are depressed, thereby effecting the
the downward stroke of the second reciprocation, which continues until the point 66
passes by the stud or roller 621; and while the portion of the cam groove from the
point 66 to the point 60 is travelling by the stud or roller 621, the latter and the
driver bar are raised and held in their elevated position. These various cams are
properly located or positioned and timed with relation to each other, to accomplish
their specific duties in sequence and at the proper time. The peripheral cams of
the disk B may and preferably will act upon a roller 3 loose on a stud 631 carried
by the arm or lever a³ (sec Figs. 2 and 14) and to which, in the present instance,
the spring 60 is fastened to enable the said spring to effect the return movement.
of the lever a³.
The work or material into which the nail or slug is driven as just described, is
supported upon a horn 6, which for regular work is preferably of the construction
shown in Fig. 3, it consisting of a substantially straight bar provided at its lower end
with a threaded shank or stem 141, extended through a threaded sleeve 1,42 on an
arm 643, resting upon the upper end of a non-rotatable shaft or rod 64, and adjustably
secured thereto by a clamping bolt or screw 6, extending through an elongated
slot 64 in the arin 643 and into a threaded socket 4 in the upper end of the rod or
shaft. The horn is preferably provided at its upper end with a revolvable cap or
tip 650 (see Figs. 3 and 4) having its stem 651 fitted into a socket 652 in the end of the
horn, and secured therein against longitudinal movement as by a pin 63, extending
through a suitable hole in the side of the horn into an annular groove in the
stem 651. The revolyable tip or cap 65° enables the work to be fed forward with a
minimum friction.
The horn 60 in its operative position is elevated, which may be accomplished by
one or more springs 6, made of wire rods bent into substantially the form shown in
Fig. 3, and having one end stationary and its opposite end engaging the under
surface of a roller 6, mounted on a stud or shaft 6" having bearings in a sleeve or
suitable support, not hereinshown, but which is secured onto a link or rod 60, firmly
fastened as by a lock nut 6 to the lower end of the shaft or rod 6", the said link being
pivotally connected at its lower end to a lever b (see Fig. 5), loosely mounted on
a shaft or arbor 67, supported in bearings in a bracket or arm 6" depending from a
cross bar 6 connecting the front legs 10 of the base A. The horn 1," is lowered a
predetermined distance after the insertion of each slug or nail, which result may be
effected by means of a cam disk fast on the main shaft 6, the said cam having in
one of its faces, a cam groove 673, (see Fig. 8) into which projects a stud or roller on
an arm 673 of a lever pivotally mounted in the head A² and having its other

page_text: arm 6" (see Fig. 8) pivotally connected to a link 70 extended down through the hollow
post or upright A¹, as hereinshown, and loosely yet positively connected at its lower
end to an arm of the lever 6", which connection may be effected as shown in
Figs. 3 and 5, by extending the rod 6 loosely through a hole in the head g of a
bolt.g', extended laterally through the arın 6 of the lever and fastened to said
arm by a nut g². The rod i below the head g of the bolt g', is screw-threaded and
receives upon it a washer g of leather or other cushioning material, an adjustable
collar or nut ', and check nuts g' g. The purpose of this connection will be
hereinafter explained. The pivotal connection between the upper end of the link 67
and the arm 6 of the lever ", may be effected as hereinshown, by means of a
hanger or forked arm secured to the lever arm 6" by a screw ", and supporting a
shaft or pin, upon which is clamped the split upper end of the link by the
screw The operation of the horn-depressing mechanism is as follows:-The cam
groove in the revolution of the cam disk in the direction indicated by the
arrow 40, Fig. 8, acts on the stud or roller carried by the arm and turns the said
arin in the direction indicated by the arrow 41, Fig. 8, thereby turning the lever
on its pivot and moving upward the lever arm, the link 6 and the arm of the
lever, the washer g³ engaging the underside of the head y of the bolt g'. This
movement lowers the opposite arm of the lever 6 and thereby lowers the link 6, the
horn shaft and the horn 610, the horn being in its lowermost position when the
highest point 70 of the cam (see Fig. 8) is in engagement with the lever arm 673.
With the construction of the cam hereinshown, the horn is inaintained in its lowered
position, while the surface from the point 70 to the point 71 is in engagement with
the lever arm 73, and the throw of the cam is of such extent as will lower the horn
away from the throat plate, a sufficient distance to afford plenty of room for the
operator to put on and remove the work from the horn, which movement of the
horn is more than sufficient to permit of the automatic feed of the work. The
automatic feed for regular work may and preferably will be accomplished as will now
be described.
The feed mechanism herein shown for regular work consists essentially of an arm
or bar c (see Figs. 1, 2, 9, 19 and 20) located below the throat plate a22, and secured
to or forming part of a rack bar c¹ (see Fig. 19), the bar c in the present instance,
being shown as adjustably secured to the rack bar c¹ by the screws c2a. The rack
bar is dovetailed into the lower arın 75 of a lever c², provided with a pivot stud or
pin 3 (see Figs. 7 and 9), which has a bearing in a socket or hub ct of the head A³,
and in which hub the pivot pin c³ is free to move longitudinally, for a purpose as
will be described.
The lever c² is provided at its upper end, as, hereinshown, with two arms c³, c, the
arın c being adapted to be engaged by a cam projection c (see Fig. 9) on the
periphery of a cam disk c', the arm c³ as hereinshown carrying a stud or roller c³,
which is projected into the path of movement of the cam projection c', and which
effects a rocking of the lever on its pivot or stud c³ to effect a positive movement of
the feed arm c in one direction. The arm c of the lever c³ is provided as hereinshown
with a roller c¹0 (see Figs. 7 and 9), which is adapted to be engaged by a projection
or cam c¹² on one face of the cam disk c, which engagement of the cam or projection c¹²
with the roller c10, effects a longitudinal movement of the lever c², which movement
is towards the front of the machine or in the direction indicated by the arrow 50,
Fig. 7, so as to bring the end of the feed arm or bar c into engagement with the
work, and when so engaged, the cam or projection c will meet the roller c' and rock
the lever c2 on its pivot, in a direction to effect a feed movement of the work, which
movement will be towards the left, viewing Fig. 1, in the arrangement of the parts as
hereinshown.
After the work has been fed forward or toward the left (viewing Fig. 1), the desired
or required distance to effect a proper spacing of the nails or slugs for regular work, it
is practically essential that the feed arm or bar c should be withdrawn from
engagement with the work in such a direction as will not disturb the work from the
position into which it has just been moved, and this withdrawal of the feed bar c may

page_text: and preferably will be accomplished by means of a spring c¹5, hereinshown as an
inclined wire spring fastened at one end to the framework or head A2, and having its
other or lower end in engagement with a collar or head c¹ on the stud c¹, carried by
the lever arm c' and upon which the roller c' is mounted.
By reference to Fig. 2, it will be seen that the upper end of the spring c¹ is located
out of line with its lower end, which causes the said spring to withdraw or move the
lever c² bodily in a rearward direction, to thereby move the pivot pin or shaft c³ in its
sleeve or hub c¹ in a direction opposite to the arrow 50, Fig. 7, and the said spring at
the same time bearing on the stud c, throws the arm c of the lever c² toward the
head of the machine, until it is arrested by a suitable stop, which movement of the
arı c carries the lever c² backward into its normal position, that is, toward the right,
viewing Fig. 1.
The extent of the said backward movement of the lever c² may be regulated by an
adjustable back stop, shown as a screw c20 carried by the arm c³ of the lever c² and
adapted to engage the head A2 of the machine. The motion of the work feed
mechanism partakes of what is commonly known as a four-motion feed. The feed bar c
is adjustable in its lever c², so as to properly position the engaging end of the lever
with relation to the work, and this adjustment may be accomplished as hereinshown,
by providing the arm 75 (Figs. 19 and 20) of the lever c² with a transverse circular
socket c22, through which is extended a shaft c23 provided with a pinion c2 in mesh
with the rack bar c¹, the shaft c3 being held from rotation, except when positively
moved, by means of a spiral spring c encircling the shaft c23 between the lever c³ and
check nuts c, the said spring acting to keep a head or collar c2 on the shaft c23 in
engagement with one side of the arm 75 of the lever c². The adjustment of the freed
bar c may be accomplished, as hereinshown, by means of a crank or handle c30
attached to one end of the shaft c23.
The parts of the machine heretofore described, are operated from the main shaft b°
of the machine, and the rotation of the shaft may and preferably will be controlled by
a clutch mechanism as will now be described.
As hereinshown, the shaft bbas fast on it a wheel or disk d provided with a
suitable friction surface d (see Fig. 2), with which co-operates a pulley d², normally
loose upon the shaft 6' and continuously revolved by a suitable belt, not hereinshown,
or in any other suitable manner.
This construction of the clutch mechanism, as thus far described, may be of any
usual or suitable make, such as now commonly employed, but, in the present instance,
the loose pulley d2 is positively engaged with the disk or wheel d', by what I prefer
to designate as the starting device or mechanism for the machine, which
starting device consists as hereinshown of a collar or yoke d³ (see Figs. 2
and 12) on the hub d of the loose pulley d², the said collar being
provided with a beveled face d' (see Fig. 2), with which co-operates a beveled face d'
of a yoke d, encircling the hub d' of the loose pulley and having its rear face d'
engaging, as hereinshown, a bearing hub d' forming a stationary part of the machine.
The yoke d is provided as hereinshown with a shank 10, to which is connected in any
suitable manner, the upper end of a link d, extending down through the hollow
upright A¹ and connected at its lower end to an arm d¹³ of a foot treadle or lever d¹4
(see Figs. 3 and 5), the lever 14 being mounted upon the shaft 6. The operation of
the starting mechanism may be briefly described as follows:
The operator depresses the treadle d, which movement elevates the arm 13, the
link d2 and the yoke d', thereby moving the beveled face d' of the said yoke upward
with relation to the beveled face d³ of the collar d³ and into substantially the position
shown in Fig. 2, the movement of the yoke d being in a vertical plane by reason of
its abutting against the hub d, and consequently as the yoke is moved upward, its
beveled face de forces the beveled collar d³ against a collar or enlargement on the
hub d of the loose pulley d², and carries the said loose pulley into engagement with
the friction surface d' of the disk or wheel d, thereby rendering the constantly driven
pulley fast on the shaft 6", and thereby setting the said shaft in rotation, when
released as will be described.

page_text: In order to stop or arrest the shaft 6 in its rotation substantially in an instant,
when the loose pulley dis disengaged from the wheel or disk d, I have provided a
novel stopping or brake mechanism consisting essentially as hereinshown of a brake
wheel do, preferably provided with a substantially V-shaped annular groove d² and
hereinshown as forming part of the disk or wheel d. The brake-wheel d20 has
co-operating with it a brake-shoe (10, fastened on the end of the lever d²²
extended into a slot do (see Fig. 2) in the upper portion of the head A2 as
hereinshown, and pivoted to the said head as at 23, the said lever having its
shorter or rear arm 80 upwardly spring-pressed, so as to normally depress the
long arm of the lever d, and engage the brake-shoe d210 with the brakewheel d²º,
.when the front end of the lever is lowered by the spring d25 shown in Fig. 2,
which spring is located within a suitable socket di in the head A
The movement of the front end of the lever just described, may be automatically
controlled so as to enable the operating parts to perform their work, by means of
the brake wheel d, with which co-operates, as herein shown, a roller 30 loosely
mounted on the front end of the lever d22, the disk or wheel d being of a sufficiently
large diameter to elevate the front end of the brake lever (22, when the full portion
of the periphery is in engagement with the roller d30, and keep the brake-shoe
disengaged from the brake wheel; and in order to permit of the movement of the
brake lever by its spring d², so as to engage the brake-shoe d210 with the brake
wheel d, the said wheel d on its periphery is provided with a cam recess, notch or
depression d³ (see Fig. 11), into which the roller do is adapted to drop a sufficient
distance to engage the brake-shoe 21 with the groove in the brake wheel d²º,
and thereby automatically stop the rotation of the shaft d" and the operation of the
machine at the proper time and substantially in an instant, as will be described.
The brake lever d may be positively operated to release the brake shoe 21° from
engagement with the brake wheel, and this result may be effected by a releasing
device under control of the operator, and which is hereinshown as a pin or rod e
extended through a suitable hole in the head A2 (see Fig. 2), and resting upon the
yoke d', the said rod or pin being adapted to have its upper end brought in contact
with the brake-lever d, to turn said lever on its pivot and lift the roll d³° out of
the recess or depression in the brake wheel, and thereby permit the brake wheel
and the shaft 6 to revolve. The upward movement of the releasing pin or rod e,
is effected as hereinshown by the yoke d', when the foot treadle d is depressed by
the operator. The pin or rod e may be lowered, as in the present instance, by
gravity. To compensate for wear in the brake shoe do and consequent change in
position of the lever (22, an adjustable device or stop on the lever d22 is provided,
which is hereinshown as a screw e¹ extended through the lever 22 in line with the
release pin or rod e, for it will be seen that, as the release pin has a fixed limit to
its upward movement, which range of movement remains the same, the screw e¹ is
adjusted so as to engage the upper end of the pin or rod e irrespective of the change
of position of the lever d22 due to wear upon the brake shoe.
The recess or depression d³¹ in the periphery of the brake wheel, is made of such
depth as will permit the roll d³ to drop into it without interfering with the engage-
ment of the shoe with its wheel (12°. When the brake shoe is in engagement with its
wheel, as represented in Fig. 2, the loose pulley d is withdrawn from engagement
with the wheel d, which may be effected in any usual or suitable manner.
recess d in the wheel may and preferably will be longer than the diameter of
The
the friction roll 30, so as to allow for a certain amount of movement or rotation of
the brake wheel due to its momentum, after the engagement of the brake-shoe with
the said wheel.
The pressure or force with which the brake-shoe d¹ is applied, may be regulated
as desired, which regulation may be effected in the present instance by means of an
adjusting screw d", extended through the rear end of the lever and acting upon the
spring d25.
The complete operation of the nail driving machine hereinshown, will now be

page_text: briefly described, when the nails to be driven are of uniform length and are driven
into the top-lift of the heel.
Let it be supposed that the wire has been properly placed in the guide-
way as, aa, which may be accomplishel by the operator rotating or turning the
sleeve a by moving the finger piece or lever a downward from the position shown
in Fig. 14, so as to turn the eccentric in its bearing in the lever a³ and move
the feed wheel a away from the stationary member a¹, thereby affording sufficient
room for the insertion of the wire between the members of the feed mechanism into
the guideway as aa. After the wire is properly placed in its guide, the sleeve a
is rotated in the opposite direction, to firmly grip the wire, by the operator turning
the lever 3 up into the position shown in Figs. 1 and 14. Let it be further.
supposed, that the machine has progressed from its starting position, which will be
hereinafter fully described, to the position shown in Fig. 1, which is accomplished
by the operator first depressing the treadle d, which moves the yoke d' upward
into substantially the position shown in Fig. 2, and engages the loose pulley d² with
the fast disk or wheel d. At the same time, the yoke d raises the releasing pin or
rode and lifts the lever d, which withdraws the brake-shoe from engagement with
the brake wheel, and permits the main shaft of the machine to be started in its
rotation. As the main shaft rotates, it causes the cam disk 671 to lower the rod b",
which movement places the lever under control of the spring 60, which presses
upward on the roller and elevates the horn until the work on the said horn is
firmly pressed up against the throat plate a", and by reason of the loose yet positive
connection of the rod b with the arm 6 of the lever be, the work on the horn is
pressed against the throat plate with a uniform and firm pressure, irrespective of
the thickness of the work and without liability of breaking or straining of parts,
the same as might occur if the rod 6" and lever 6 were connected so as not to
For instance, a thick portion
permit of movement of one independent of the other.
of the work might engage the throat plate, before the rod 6" had been brought to
its lowest position by the cam b". In this case, the loose connection referred to,
permits the rod to pass through the hole in the head g of the bolt g' without
moving the lever bca.
At or about the time the work has been brought firmly against the throat plate,
the driver operating cam B operates on the driver to effect what may be termed the
first reciprocation of the driver bar, which reciprocation is effected by the portion
of the cam groove from the point 60 to the point 61.
On the first reciprocation of the driver bar, the driver is carried through the
throat (see Fig. 23), and into the top lift or work, so as to form or prick a hole,
into which the nail is to be driven on the second reciprocation of the driver bar,
as will be described. After the hole is pricked in the work, the driver bar is raised..
to its full upward limit and into the position represented in Figs. 1 and 4, in
which position it remains while the wire is being fed into the throat and the nail
or slug formed.
While the driver bar is reciprocated to impart to it the functions of an awl as
above described, the wire guide a is out of the path of movement of the said
driver, to leave a clear path for the passage of the driver into the throat a". After.
the driver has pricked the hole and returned to the position shown in Fig. 1,
the wire guide is moved into the path of movement of the driver, and its
guideway aa is placed into alignment with the throat a, and this movement. of
the wire guide is effected as above described by the portion of the cam disk B
between the points 50-51, Fig. 13, acting on the roller 60 carried by the lever a³.
After the lever a³ has been turned on its pivot as described, so as to place the wire
guide in alignment with the throat, the feed of the wire takes place, which is
effected as above described, by the cam 61° engaging the arm or lever b¹³ fast on
the shaft, so as to move the pawl-carrying arm a backward a number of teeth
on the ratchet wheel a sufficient to produce the feed desired, and the actual feed
of the wire in the present instance is effected by means of the spring 61 returning.
the lever or arm b12 back to its normal position represented in Fig. 10, which

return movement of the arm 612 rocks the shaft a and moves the feed wheel a
the direction opposite to the arrow 21, Fig. 14, and feeds the wire down into the
throat, 21 The length of the wire fed into the throat is regulated by means of
the adjusting screw 613, which positions the end of the lever 612 with relation to the
under surface of the cam 61, so that a greater or less length of the cam will engage
the lever.62, the, longer the engagement of the lever 62 with the under surface of
the cam 610, the greater the movement of the pawl-carrying arm a' in the direction
indicated by the arrow 21, and consequently the greater the rotation of the feed
wheel in the direction opposite to the arrow 21.
It will be understood that the set screw 6 when once adjusted ensures a uniform
feed of the wire,, and, consequently nails of uniform length will be cut and driven
into the work until the said set screw is adjusted for a different length of nail.
While the wire is being fed into the throat as described, the carrier or lever (3
remains stationary until the wire feed mechanism has accomplished its work. At
or about, the time the wire feed mechanism has finished its work, the portion of the
cam B between the point 52-53 acts on the roller 6 and turns the lever or carrier a³
onits, pivot, so,as. to move the wire guide further in the saune direction across
the path of movement of the driver, and thereby bring the cutters into action, the
movable cutter shearing the portion of the wire in the throat so as to form
a substantially smooth surface on the nail in the throat, and a substantially V-shaped
point, on the portion of the wire remaining in the guide. The nail or slug cut
from the wire, is now in the throat and is in position to be driven, but in order
to enable it to be driven, the wire guide must be withdrawn from the path
of movement of the driver, which may be effected by the spring 6, as herein shown,
acting on the carrier or lever, a³, as soon as the point 53 on the cam disk B passes
by. the roller..630 on the said lever. The spring 60 carries the lever. and its
attached parts back into their starting position substantially represented in Fig. 1.
The path of movement of the driver is now clear, and the second reciprocation
of the driver is effected by the cam groove 620 between the portion 62 and 66 (see
Fig. 13), which moves the driver bar and its attached driver downward, so that the
end of the driver will force the nail into the hole in the top lift formed by the
driver on the downward movement of its first reciprocation, and the said driver is
arrested in its downward movement, at or about the time the point 66 of the cam
engages the roller 621; and when the driver bar is so arrested or stopped, the end
of the driver is preferably substantially flush with the under surface of the throat
plate, in which position it remains, while the portion of the cam groove 620 from the
point 66 to the point 60 is in engagement with the roller 21.
As soon as the nail has been driven into the top-lift, the horn commences to be
lowered, and at the beginning of the movement of the horn away from the throat
plate, the feed of the work takes place. The downward movement of the horn, as
above described, is effected by means of the cam groove 6" in the cam disk b", while
the four-motion work feed is accomplished by means of the cams c¹, c', and the
spring c¹5, as above described, acting on the lever c². The work having been fed,
the horn continues to descend, and at or about the time the horn has reached its
lowermost position, the cam, recess or lepression 31 in the brake wheel comes in
line with the roller on the brake lever d", and if the releasing pin e is in its
lowered position out of contact with the brake-lever d", the latter will be turned
on its pivot by the spring d", so as to engage the brake-shoe do with the brake
wheel and thereby automatically stop the machine with the horn in its lowered
position.
.
If, however, it is desired to continue the operation of the machine, the
operator will maintain his foot on the treadle 4, and thereby keep the releasing
pin, or device e in, engagement with the brake lever d, and consequently hold the
brake shoe 210 out of engagement with the brake wheel, while the recessed portion
of the periphery of the disk or wheel d

page_text: driver operating cam B is stopped with the point 60 of the cam groove 620 in
engagement with the roller 621, (see Fig. 23) which is the starting position of the
machine, so that, as above described, when the operator first starts the machine;
the first operation will be the throwing down of the driver bar beyond the lower
face of the throat and into the material to punch a hole therein, after which it is
returned to the position shown in Fig. 1, and the remaining successive operations
performed as above described.

By means of the threaded shank 64 on the horn, the latter may be adjusted
vertically with relation to the throat plate, and a lateral adjustment may be obtained
by the elongated slot 6 and screw 6, to enable the tip of the horn to be' adjusted
with relation to the counter of the shoe to compensate for heels of different sizes.
In some classes of work, a variable feed of the wire is desirable in order to obtain
mails of a length suitable to or commensurate with the thickness of the work into
which the nails are drive; and to effect this result, on the machine herein shown;
I have provided what may be termed an automatic feed attachment, which consists
of a bevelled or inclined block or piece go (see Figs. 1 and 10) on the upper end of a
rod adjustably and removably 'secured to the horn shaft 64; preferably as herein
shown. Referring to Fig. 6, the rod gl² is secured by a set screw 13 in a socket or -
hole in a screw g, having its shank inserted into a threaded socket in the bolt or
screw, which, as above described, is screwed into a socket in the horn
shaft 64. The bevelled block g co-operates with a roll g¹5 (see Fig. 10) loose on a
stud on the lower end of the lever 12. When it is desired to obtain a uniform
feed of the wire, the rod g¹² may be lowered as shown, so that its bevelled block 10
will not engage the roll g15 with the horn in its elevated position, but when it is
desired to obtain a variable feed of the wire, the rod 12 is raised and secured by the
set screw 13 in its adjusted position, so that the bevel block' will engage the
roll g, when the lever is turned by its spring 10 in the act of feeding the wire.
When the variable feed is used, the set screw 18 is turned back sufficiently to enable
the lever 1 to be brought by its spring into engageinent with the bevelled block
or back stop g, and as the position of the bevelled back stop g is automatically
governed by the thickness of the work, the position of the lever b, with relation to its
operating cam 60 is automatically varied, and consequently the 'length of the nail is
automatically controlled by the thickness of the work.
The machine as thus far described is adapted to perform what may be termed
regular work, that is work in which the nails are driven at a uniform distance from
the edge of the work, and which latter is fed forward by the feed mechanism on the
head of the machine. In some classes of work, technically known as quilting, it is
desirable to drive the nails in an irregular order so as to form designs on the work;
principally on the outer soles before the latter are secured to the upper and inner
sole, and to enable such work to be performed with the machines hereinshown I
have provided what may be termed a quilting work support (see Fig. 24) which is
designed to replace the horn " used for regular work.
:
The quilting support may and preferably will be made as shown in Figs. 24 to 27"
inclusive, and consists of a rod or post g², provided with the screw-threaded lower
end g and with a collar g22, against which rests the lower end of a spiral spring
encircling the upper end of the said rod or post and bearing against a sleeve g fitted
over the upper end of said rod or post. The sleeve g21 has a slot g2 at its lower end;
through which is extended into the rod 92, a screw 2 forming a stop to limit the
movements of the 'sleeve 2 on the rod 20. The sleeve has secured to its upper
end a second sleeve 27, of smaller internal diameter than the sleeve g² and provided
on one side with a beveled portion go, with which co-operates a beveled shoulder g³¹
on the end of a lever g³, extended down into a socket 933 in the upper end of the rod
or post go, and pivoted at g³ between the walls of a longitudinal slot 35 in the upper
part of said post or rod, so that the pivot of the said lever is at one side of the center
of the rod or post g²º.
:
The lever g is provided with a longitudinal bore, through which extends an awl
carrying bar or rod g, having attached to its upper end an awl or feed point 936 and
yieldingly supported at its lower end by a spring 937 (see Fig. 25).

page_text: The sleeve g27 has secured to it a cover or top plate go, provided with an elongated
slot g in line with the awl g, and the said cover or plate forins the upper surface
of the quilting post, which supports the outer sole g2 against the throat plate a²².
The awl carrying lever 932 is adapted to be turned in the direction indicated by
arrow gs, to effect the feed of the work g12, by the engagement of the bevel g³ with the a
bevel 930, and is returned to its normal position by the spring g". The length of the
feed movement may be regulated by the adjusting screw 9, which positions the
bevel g³ with relation to the bevel g³°.
When it is desired to quilt the outer sole 912 with the machine hereinshown and
described, the horn 6" employed in slugging, is removed and the quilting post sub-
stituted therefor, as shown in Fig. 24, and further the work feed bar c employed in
slugging, is either removed from its lever c² or withdrawn sufficiently far to afford
room for the outer sole to be turned by the operator in any direction, so as to follow
the design on the outer sole, such, for instance, as the manufacturer's initials.
In operation, the outer sole 912 is forced against the throat a", by the spring g³,
and when the post 9" is elevated by the spring 600, the lever g³2 is moved upward and
the feed point or awl gs is carried through the slot g", into the outer sole, and when
the bevel g on the lever g³ engages the bevel g, the upper end of the lever g³¹ and
the awl gare moved in the direction indicated by arrow g3, which movement
effects the feed of the work over the top plate of the quilting post, as represented in
Fig. 26.
When the work has been fed forward as described, the post g20 is lowered by the
cam disc as above described, but the work 92 is kept in engagement with the
throat plate by the spring 923. As the post 2 is lowered, the lever g is returned
from the position shown in Fig. 26 to its normal position shown in Fig. 25, and as
the post g descends, the awl is withdrawn from the work, in a substantially
- straight path until it clears the work so as to prevent tearing the work or moving it
backward over the top plate.
When the machine is used for quilting, the nails are of uniform length and, therefore,
the variable feed rod g12 is rendered inoperative.
