WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte,
Paris. "IMPROVEMENTS IN MACHINES FOR DRIVING TACKS CUT FROM A CON-
TINUOUS WIRE, FOR THE PURPOSE OF LAYING THE SOLES OF BOOTS AND SHOES AND
FOR LASTING THE SAME." [A communication from abroad by Louis Goddu, of
Winchester, Middlesex, Massachusetts, United States of America, Machinist.]
This Invention relates to certain improvements in machines for driving tacks cut
from a continuous wire, for the purpose of laying the soles of boots and shoes and
for lasting the same, and consists in a combination of devices whereby the tacks in
a continuous wire are automatically fed to the drive tube, where they are cut off
or separated from the wire and driven in by a spring driver.
The Invention also consists in a novel method or means for feeding the shoe to
the end of the drive tube.
A standard supports a head or frame, on the upper front part of which is
arranged a spring driver bar of well-known construction. Within the head is
mounted a horizontal shaft, upon which is secured a cam and a roller which bears
upon the cam and is attached to the upper end of a lever arm, the said roller being
held against the cam by means of a coiled spring attached to the arm and to the
head or main frame. The lower end of the arm is attached to a shaft, mounted in
Prins di

page_text: a sleeve or bearing which forms a part of the head. To the front end of the shaft
on the face of the head is attached a plate, and to one side of plate is attached a
nail guide.
The nail guide consists of a metal block formed in two equal parts, and provided
with two passages or openings extending through the same, one passage being for
the tacks and the other for the nail driver. To one side of the nail guide is
attached an adjustable flat spring for the purpose of preventing the withdrawal
or backward movement of the nail wire after it has been fed into the nail tube.
The continuous nail wire, which is formed in successive steps of nails, the con-
nection of each point to the head of the next nail being continuous, passes from a
reel into the upper end of the block or nail guide, and out of the same at a point
contiguous to the end of the spring, thence downward on the outside of the nail
guide into a guide nose which is attached to the front lower portion of the head or
main frame. The lower end of the block is moved laterally by means of its con-
nection to the plate on the shaft on the upward motion of the nail driver a sufficient
distance to admit of the nail entering the passage of the guide nose, after which
the lower end of the block is returned to its position to bring the drive way or
passage in the block in line with the passage in the guide nose.
A block is attached to the head, and provided with a passage through the same,
to act as a guide to the nail driver which is attached to the lower end of a driver
bar.
Upon the front end of the shaft is an eccentric provided with a cam, which
serves to elevate the driver through a dog attached to the same at each revolution
of the shaft.
To one side of a collar which is supported on the cam is pivoted or hinged a
lever arm, having an oblong slot, in which is fitted a block, which is secured to the
head by means of a bolt. The arm is for the purpose of operating the feed for the
boot or shoe sole, and through the agency of the cam has imparted to it a vertically,
reciprocating, and an oscillating motion upon the block, which latter admits of
being adjusted to the several positions to adapt it to any required varying throw
of the feed, as required. A feed foot is adjustably attached by means of a slot and
bolt to the lower end of the arm, its end extending to the rear of the nail tube or
guide nose.
Forming a part of the collar, and extending from the opposite side from the
lever arm, is an arm at an inclination; this arm is provided with a slot in which
is fitted a block, which is attached to a bolt secured in a slotted arm forming a
part of the head. The bolt is adjustable in the slot, so as to adapt the motion of
the arm to vary the throw of the cutter arm, as required.
To the arm is pivoted an arm extending inwardly at an angle with the first arm,
and terminating in a wedge-shaped edge, which is caused to bear against the lower 4
side of the nail guide by means of a spring attached to the first arm and the head
or main frame.
To the lower end of the second arm is attached an adjustable cutter, which is
caused by the peculiar motion of the first arm to feed the continuous tack wire to
the nail tube and then to cut off a tack, the lower end of the nail tube being 4
caused to move aside to allow the cutter to pass across the top of the nail tube for
the purpose.
The continuous nail wire is wound on a reel, mounted on a shaft attached to an
arm projecting from the head or main frame.
The first-named shaft is put in motion by power applied to a loose pulley, which 5
is provided with bevelled edges corresponding with similar bevelled edges on a
curved or dish-shaped disk, firmly secured to the shaft and constituting a friction
clutch.
The loose pulley and the clutch are kept separate by an intervening spring, and
the contact of the two bevelled edges is effected by means of a rod, which is caused 5
to force the loose pulley towards the clutch upon depressing a pedal.

Paris. IMPROVEMENTS IN MACHINES FOR DRIVING TACKS CUT FROM A CON-
TINUOUS WIRE, FOR THE PURPOSE OF LAYING THE SOLES OF BOOTS AND SHOES AND
FOR LASTING THE SAME." A communication from abroad by Louis Goddu, of
Winchester, Middlesex, Massachusetts, United States of America, Machinist.
This Invention relates to certain improvements in machines for driving tacks
cut from a continuous wire, for the purpose of laying the soles of boots and shoes
and for lasting the same, and consists in a combination of devices whereby the tacks
in a continuous wire are automatically fed to the drive tube, where they are cut off
or separated from the wire and driven in by a spring driver.
The Invention also consists in a novel method or means for feeding the shoe to
the end of the drive tube.
Referring to the Drawings,-
Figure 1 is a side elevation of machine embodying my Invention, showing a
friction clutch and pulley in section.
Figure 2 is a front view of the head of the machine with the nail reel attached.
Figure 3 is an enlarged view, in detail, of the mechanism for feeding the work,
and also for feeding and cutting the tack wire.
Figures 4, 5, and 7 are views in detail of separate parts of the machine.
Figure 6 represents the tacks as formed in a continuous wire.
Similar letters indicate like parts in the several Figures.
A is a standard supporting the head or frame B, on the upper front part of which
is arranged a spring driver bar of well-known construction. Within the head B
is mounted a horizontal shaft E, as shown, upon which is secured the cam F; F' is
a roller which bears upon the cam F, and is attached to the upper end of a lever
arm G. The said roller being held against the cam F by means of a coiled spring
attached to the arm G and to the head or main frame. The lower end of the arm G
is attached to a shaft I, mounted in a sleeve or bearing K, which forms a part of
the head B. To the front end of the shaft I, on the face of the head B, is attached
a plate L of the form shown in Figure 7, and to one side of plate L is attached the
nail guide M, as shown in Figures 1 and 3.
The nail guide M consists of a metal block formed in two equal parts, and pro-
vided with two passages or openings extending through the same, as indicated in
dotted lines in Figures 1 and 3, one passage being for the tacks and the other for
the nail driver. To one side of the nail guide M is attached an adjustable flat
spring m, for the purpose of preventing the withdrawal or backward movement of
the nail wire after it has been fed into the nail tube.
The continuous nail wire, which is formed as shown in Figure 6, passes from the
reel b into the upper end of the block or nail guide M, and out of the same at a
point contiguous to the end of the spring m, thence downward on the outside of
the nail guide M into the guide nose O, which is attached to the front lower portion
of the head or main frame B. The lower end of the block M is moved laterally by
means of its connection to the plate L on the shaft I on the upward motion of the
nail driver a sufficient distance to admit of the nail entering the passage of the guide
nose O, after which the lower end of the block M is returned to its position to
bring the drive way or passage in the block in line with the passage in the guide
nose O, as shown in Figure 2.
N, Figure 1, is a block attached to the head B, and provided with a passage
through the same, to act as a guide to the nail driver Q which is attached to the
lower end of the driver bar P.

page_text: Upon the front end of the shaft E is an eccentric R, provided with a cam T of
the form shown in Figure 5, which serves to elevate the driver P through a dog p
attached to the same at each revolution of the shaft E.
To one side of the collar S, which is supported on the cam T, is pivotted or
hinged the lever arm V, having an oblong slot, in which is fitted a block Vi
(Figure 3), which is secured to the head B by means of a bolt. The arm V is for
the purpose of operating the feed for the boot or shoe sole, and through the agency
of the cam T has imparted to it a vertically reciprocating and an oscillating motion
upon the block V', which latter admits of being adjusted to the several positions
V2, V3, or V, to adapt it to any required varying throw of the feed, as required;
W is the feed foot adjustably attached by means of a slot and bolt to the lower
end of the arm V, its end extending to the rear of the nail tube or guide nose O.
Forming a part of the collar S, and extending on the opposite side from the lever
arm V, is an arm U at an inclination, as shown in Figures 2 and 3. The arm U
is provided with a slot U¹, as shown in Figure 3, in which is fitted a block which
is attached to a bolt u, secured in a slotted arm x, forming a part of the head B.
The bolt u is adjustable in the slot x, so as to adapt the motion of the arm U to
vary the throw of the cutter arm Y, as required.
To the arm U is pivotted the arm Y, extending inwardly at an angle with the
arm U, and terminating in a wedge-shaped edge, which is caused to bear against
the lower side of the nail guide by means of a spring y attached to the arm Û and
the head or main frame B.
To the lower end of the arm Y is attached an adjustable cutter z, which is caused
by the peculiar motion of the arm U to feed the continuous tack wire to the nail
tube O, and then to cut off a tack, the lower end of the nail tube M being caused
to move aside to allow the cutter to pass across the top of the nail tube Ŏ for the
purpose.
The continuous nail wire is wound on a reel b, mounted on a shaft attached to
an arm a projecting from the head or main frame, as shown in Figure 2.
The shaft E is put in motion by power applied to the loose pulley f, which is
provided with bevelled edges corresponding with similar bevelled edges on a
curved or dish-shaped disc g firmly secured to the shaft E, and constituting a friction
clutch.
The loose pulley and the clutch g are kept separated by an intervening spring h,
and the contact of the two bevilled edges is effected by means of a rod d, which is
caused to force the loose pulley towards the clutch g upon depressing the pedal A'.
Having now described and particularly set forth the nature of the said Invention,
and the manner of carrying the same into effect, I would have it understood that
what I claim is,-
First. The devices shown by which the tack wire is automatically fed to the
drive tube, and there cut or separated and driven, substantially as described.
Second. The manner and devices for feeding the shoe to the end of the driver,
substantially as described.
In witness whereof, I, the said William Morgan-Brown, have hereunto set
my hand and seal, this Fourth day of March, in the year of our Lord One
thousand eight hundred and seventy-eight.
WILLIAM MORGAN-BROWN. (L.B.)
