PROVISIONAL SPECIFICATION left by the said John Garrett Tongue
at the Office of the Commissioners of Patents, with his Petition,
on the 16th July 1874.
I; JOHN GARRETT TONGUE, of the Firm of Tongue & Birkbeck,
5 Patent Agents and Engineers, of 34, Southampton Buildings, Chancery
Lane, in the County of Middlesex, do hereby declare the nature of the

page_text: The incline H is composed of several distinct, angles, as shown in
Figure 7, the tack channel running at an angle of about 45 degrees
within the cylinder and through the head G; and at a certain distance
from said head the incline and channel are steeper to cause each tack in
succession to drop rapidly down to the extreme front end of the channel,
which is horizontal.
The incline H is by a rod I connected with the cam arms J which
operate the feeding cylinder back and forth. The rod I is screwed into
the rear end of the incline, and likewise screwed into an oscillating
nut 6 between the two cam arms J, whereby said rod is rendered
adjustable for the purpose of giving the desired movement of the incline
to and from the hammer.
On the back of the standard A below the connecting rod I is a
vertical tube d containing a spiral spring e, upon which is placed a
pin having its upper end bevelled on both sides to form an edge,
which is held by the spring against and across the screw threads on
rod I, and forms a "rattler" for the purpose of imparting a jarring
motion to the incline, thereby causing the tacks to slide down the same
to the separator.
!
The stationary head G is funnel shaped on the inside of the cylinder E
for the purpose of preventing the tacks choking up the outlet of the
incline, and for carrying back to the rear of the feeding cylinder surplus
tacks, to be again raised by the buckets or wings 9g on the inside of the
cylinder preparatory to being dropped on the apron that feeds the
incline.
At a suitable point in the tack channel a of the incline H is a spring
pin i on each side, as shown in Figure 11, for the purpose of arresting
the downward movement of the tacks at such point prior to their
separation. The inner ends of these pins are bevelled or pointed to allow:
the tacks when moved by the feeding device to force them outwards
and pass them.
The incline H is made of any non-magnetic material, and at the point;
where the separation of the tacks takes place a hardened steel seat h is
inlaid into the incline, upon which seat the under part of the tack heads
slide while being separated.

page_text: K represents the feeding device, in the front end of which is a
hardened steel pointer / forced downward by a spiral spring 7. This
:pointer is used as the medium for holding and moving each tack by its
pressure upon the head of the same. At the foot or termination of the
incline H is formed a recess or cup m, as shown in Figure 9, for the
purpose of stopping, holding, and presenting the tack to the hammer....
In a slot in the stationary. head G within the cylinder E is pivoted a
brush n held by a spring n', as shown in Figure 10. Upon the inside
of the cylinder E are pins ², which as the cylinder revolves strike the
upper end of the brush and turn it to one side, the spring n' returning it
to its former position. The brush 12 thus sweeps back and forth imme-
diately at or above the outlet of the incline H for the purpose of keeping
the track free from obstructions.
The tack channel a in the incline H at or near the rear end extends
through to the bottom, and is larger underneath than at the top, as
shown in Figure 10, for the purpose of permitting false or imperfect
tacks to drop out and prevent clogging up. L represents the hammer,
the upper end of which extends up into an adjustable screw sleeve M
fastened in the upper end of the standard A: In this sleeve is a spiral
spring p, which is placed and compressed upon the top of the hammer
for the purpose of increasing or diminishing the distance between the
head of tack in presentation cup at foot of incline and point of
hammer which takes up the same, and also for the purpose of doing
away with the concussion consequent upon the return stroke of the
hammer when the machine is running at full speed.
N represents a loose sleeve surrounding the hammer L, to which sleeve
are attached the rods O connecting it with the operating lever P, within
this sleeve is a spiral spring s against which an adjustable collar t on the
hammer strikes at the down stroke thereof. This spring operates as a
cushion to relieve the machine from the jar of the downward stroke, and.
elevates the hammer in advance of the regular movement of the parts.
This spring also compresses the spring p on top of the hammer in
advance of the regular movement of the parts. The bottom spring of
hammer is for the purpose of increasing or diminishing the force of the
blow to be imparted by the hammer to the tack to be driven.
The steel pointer k is attached or placed in a pivoted plate ¹ in the
feeding device K, which plate has a pin entering a slot w in an arm R.

page_text: This slot is made in such a manner as to operate the pointer or separator
to cause the tacks to slide down the incline to receiver m on the
backward movement of the cylinder.
The feeding device also acts as a guard to prevent tacks from moving
out of position consequent upon the jar caused to the machine by blows
from a hammer in the hands of the operator while fitting the upper for
receiving tacks.
In the standard A below the feeding cylinder is a horizontal screw
rod f forked or slotted at its outer end to receive a slottle plate y
adjusted up and down by means of a screw z. This plate acts as a
guide or rest for the purpose of enabling the operator to drive tacks at
any desired distance from the outer edge of the last.
S represents the base of the machine provided with a projecting
arm T, in the end of which is formed a ball-and-socket joint a¹ for
connecting the rod V that supports the jack W for holding the. last.
In the rods V is a slip joint at 6' for raising and lowering the jack.
In the base S in suitable bearings is a shaft d¹ upon the inner end of
which is a wheel A¹ provided with a crank pin e'. This crank pin works
in a slotted lever B₁ pivoted at one end to a post in the base, and to the
other end is pivoted a rod C¹ which connects with the lever P for
operating the same. On the outer end of the shaft d' is placed the
band wheel D¹ to which the power is connected. This wheel is placed
loosely on the shaft and is by a peculiarly arranged clutch connected
with a pulley G¹ which connects by a belt f¹ with the head C of the
feeding cylinder.
In the hub of the wheel D' is formed a circular recess h¹ concentric
with the wheel, and within the same is a series of notches i, as shown
in Figure 5. On the side of the pulley G¹ is pivoted an arm m³ provided
with a cam-shaped projection 2 which is to enter the notches ¹. This
arm is held by a spring n² against a pin or stop p¹ when the clutch is in
gear. If however the arm m¹ is raised from this pin to and against a
pin p, the projection will be moved out of the notch i, throwing it
out of gear.
On the side of the boxing for the shaft d¹ is a tube containing a
5 spring bolts which extends across the opening between the pulley G¹
and the hub of the wheel D', and forms a stop for the arm m¹ to lift it
1

page_text: .
from the pin p' and throws it out of gear. By means of a treadle E¹ and
elbow lever H the bolt s¹ is drawn back, when the spring n² at once
throws the clutch in gear again. By this device an intermittent motion
may be given to the feeding cylinder, and the tacks fed on the incline
only when the machine is operated for presenting tacks to hammer.
By the downward movement of the rear end of the operating lever P,
the hammer L is raised and caught by a spring bolt in the arm B of thic
frame. At the same the feeding cylinder is by the cam levers J moved
forward, presenting a tack in the cup m to the hammer, which tack is
instantly drawn to it by the magnetic influence of the hammer.
At the upward stroke of the rear end of the lever P the feeding
cylinder is drawn backward, during which movement the steel pointer k
draws or pushes. one tack beyond the spring pins i, i, which held it so as
to slide down the incline into the cup m, to be presented to the hammer
at the next forward movement of the cylinder. As the front end of the
lever P descends it releases the hammer L, and this is by the spring p
thrown forcibly downward to force the tack into the boot or shoe, and
the hammer is instantaneously raised a certain distance by the action of
the spring & within the sleeve N. The feeding cylinder in this case is
revolved by the belt f¹, as above described, and the last is held by the g
operator close up against the guide or rest y, the operator having his
foot upon the treadle E¹.
.
To stop the movements of the machine the operator has only to

same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
This Invention relates to the construction and arrangement of tack
driving machines for the manufacture of boots and shoes.
In order to enable others. skilled in the art to which this Invention
appertains to make and use the same I will proceed to describe the con-
struction and operation of this improved machinery, reference being
Omade to the annexed Drawings, in which Figure 1 is a side elevation

the machine; Figure 4 is a vertical section of the same through, the
line 2, 2, Figure 3..

page_text: Figure 9 is a side view of the stationary lead of the head of cylinder.
Figure 10 is a cross section of the feeding cylinder through the
line x, x, Figure 7.
Figure 11 is a front view of the stationary head, showing section
through incline H at y, y, Figure 9.
Figure 12 is a front view of the hammer; Figure 13 is a side view of
the same partly in section, including the devices immediately connected
therewith..
:
· Figures 14, 15, 16, 17, and 18 show several views and parts of a
similar machine to that before referred to drawn on a larger scale, the
same letters indicating corresponding parts in all the Figures.
A represents the main standard of the tack driving mechanism, the
upper end of which is curved forward to form the upper bearing for the
vertically operating hammer, the lower bearing for the same being
formed in the front end of an arm B projecting from the standard.
Below this arm B is the feeding cylinder, composed of a back head C,
with hub D entering a recess in the front of the standard A. From the
front of the head C projects the shell F, the front end of which fits over
a shoulder on the front stationary head G. This head is secured to the
incline H, passing through it, which incline is grooved on its upper edge
to form the tack channel a.
The incline H is composed of several distinct angles, as shown in
Figure 7, the tack channel running. at an angle of about 45 degrees
within the cylinder and through the head G, and at a certain distance
from said head the incline and channel are steeper to cause each tack in
succession to drop rapidly down to the extreme front end of the channel,
which is horizontal.
The incline H is by a rod I connected with the cam arms J, which
operate the feeding cylinder back and forth. The rod I is screwed into
the rear end of the incline, and likewise screwed into an oscillating nut b

page_text: :
between the two cam arms J, whereby said rod is rendered adjustable for
the purpose of giving the desired movement of the incline to and from
the hammer.
On the back of the standard A below the connecting rod I is a vertical
tube d, containing a spiral spring e, upon which is placed a pin f, having
its upper end bevelled on both sides to form an edge, which is held 'by
the spring against and across the screw threads on rod I, and forms a
"rattler" for the purpose of imparting a jarring motion to the incline,
thereby causing the tacks to slide down the same to the separator.
The stationary head G is funnel shaped on the inside of the cylinder E
for the purpose of preventing the tacks choking up the outlet of the
incline, and for carrying back to the rear of the feeding cylinder surplus
tacks to be again raised by the buckets or wings g on the inside of the
cylinder, preparatory to being dropped on the apron that feeds the
incline.
At a suitable point in the tack channel a of the incline H is a spring
pin i on each side, as shown in Figure 11, for the purpose of arresting
the downward movement of the tacks at such point prior to their
separation. The inner ends of these pins are bevilled or pointed to allow
the tacks when moved by the feeding device to force them outward and
pass them.
The incline H is made of any non-magnetic material, and at the point
where the separation of the tacks. takes place a hardened steel seat / is
inlaid into the incline, upon which seat the under part of the tack heads
slide while being separated.
K represents the feeding device, in the front end of which is a
hardened steel pointer forced downward by a spiral spring 1; this
pointer is used as the medium for holding and moving each tack by its
pressure upon the head of the same. At the foot or termination of the
incline H is formed a recess or cup m, as shown in Figure 9, for the
purpose of stopping, holding, and presenting the tack to the hammer.
In a slot in the stationary head G within the cylinder is pivot a
brush n held by a spring n', as shown in Figure 10. Upon the inside
of cylinder E are pins n², which as the cylinder revolves strike the upper
cnd of the brush and turn it to one side, the spring n¹ returning it to its
former position. The brush n thus sweeps back and forth immediately

page_text: at or above the outlet of the incline H for the purpose of keeping the
track free from obstructions.
The tack channel a in the incline H at or near the rear end extends
through to the bottom, and is larger underneath than at the top, as
shown in Figure 10, for the purpose of permitting false or imperfect
tacks to drop out and prevent clogging up. L represents the hammer,
the upper end of which extends up into an adjustable screw sleeve M
fastened in the upper end of the standard A. In this sleeve is a spiral
spring p, which is placed and compressed upon the top of the hammer
for the purpose of increasing or diminishing the distance between the
head of tack in presentation cup at foot of incline and point of hammer
which takes up the same, and also for the purpose of doing away with
the concussion consequent upon the return stroke of the hammer when
the machine is running at full speed.
N represents a loose sleeve surrounding the hammer L, to which
sleeve are attached the rods O connecting it with the operating lever P.
Within this sleeve is a spiral spring 8, against which an adjustable
collar on the hammer strikes at the down stroke thereof. The spring
operates as a cushion to relieve the machine from the jar of the down-
ward stroke, and elevates the hammer in advance of the regular move-
ment of the parts. This spring also compresses the spring p on top
of the hammer in advance of the regular movement of the parts. The
bottom spring of the hammer is for the purpose of increasing or dimin-
ishing the force of the blow to be imparted by the hammer to the tack
to be driven.
The steel pointer k is attached or placed in a pivotted plate ¹ in the
feeding device K, which plate has a pin v entering a slot win an arm R.
This slot is made in such a manner as to operate the pointer or separator
to cause the tacks to slide down the incline to receiver m on the back-
ward movement of the cylinder.
The feeding device also acts as a guard to prevent tacks from moving
out of position consequent upon the jar caused to the machine by blows
from a hammer in the hands of the operator while fitting the "upper"
for receiving tacks.
In the standard A below the feeding cylinder is a horizontal screw
rod f, forked or slotted at its outer end to receive a slotted plate y
adjusted up and down by means of a screw 2. This plate acts as a

page_text: guide or rest for the purpose of enabling the operator to drive tacks at
any desired distance from the outer edge of the last.

in the end of which is formed a ball-and-socket joint a¹ for connecting
the rod V that supports the jack W for holding the last. In the rods V
is a slip joint at 6 for raising and lowering the jack.
upon the inner end of
In the base S in suitable bearings is a shaft d³,
which is a wheel A¹ provided with a crank pin s¹. This crank pin works
in a slotted lever B¹ pivoted at one end to a post in the base, and to the
other end is pivoted a rod C¹, which connects with the lever P for
operating the same. On the outer end of the shaft d' is placed the band
wheel D¹ to which the power is connected. This wheel is placed loosely
on the shaft, and is by a peculiarly arranged clutch connected with a
pulley G³, which connects by a belt f¹ with the head C of the feeding
cylinder.
In the hub of the wheel D¹ is formed a circular recess h¹ concentric.
with the wheel, and within the same is a series of notches ¹³, as shown
in Figure 5. On the side of the pulley G is pivotted an arm m¹ provided
with a cam-shaped projection n', which is to enter the notches. This.
arm is held by a spring n² against a pin or stop p¹ when the clutch is in
gear; if however the arm m¹ is raised from this pin to and against a
pin p the projection n¹ will be moved out of the notch , throwing it
out of gear.
On the side of the boxing for the shaft is a tube containing a spring
bolt s', which extends across the opening between the pulley G' and the
hub of the wheel D¹, and forms a stop for the arm m¹ to lift it from the
pin p¹, and throws it out of gear. By means of a treadle E¹ and elbow
lever H' the bolt 8' is drawn back, when the spring n² at once throws the
clutch in gear again. By this device an intermittent motion may be
given to the feeding cylinder, and the tacks fed on the incline only when
the machine is operated for presenting tacks to hammer.
.
· By the downward movement of the rear end of the operating lever P-
the hammer L is raised and caught by a spring bolt in the arm B of the
frame. At the same time the feeding cylinder is by the cam levers J
moved forward, presenting a tack in the cup m to the hammer, which
tack is instantly drawn to it by the magnetic influence of the hammer.
