PROVISIONAL SPECIFICATION
Improvements relating to the Manufacture of Boots and Shoes
I, THOMAS COWBCBN of Spring Villa, Brook Street, Gloucester in the
County of Gloucester Engineer, do hereby declare the nature of this invention
to be as follows
-
The object of this invention is to provide in machine-made boots, for a smooth
insole, that is to say, an insole which presents no projections in the shape of the
points of the brads or pegs which are used in attaching the upper to the insole, as
is usually the case in machine-made boots & shoes, and is obviously a great
objection to this class of boot, and a source of discomfort to the wearer This
object is effected by causing the awl or piercer to piece the insole to only part of
its thickness, and by providing pegs which are of a such a length as to penetrate the
insole the same distance only as the piercer
It is well known that the thickness of the sole, varies according to the part of
the boot, that is to say, the sole at the waist will be thinner than the sole at the
ball of the foot, and consequently the piercer must penetrate a less depth, and the
pegs must be shorter for one part of the sole than for another, and I therefore
provide means whereby the movement of the piercer, and the length of the peg,
will be regulated as required
In carrying out this invention with respect to lasting, I place the upper of the
boot or shoe on an iron last carried in the machine by a Jack or holder, as usual,
and as each portion of the upper is pulled over the last, I secure it to the insole by
automatically piercing a hole through the upper, and into the insole, and placing
therein a pin or sciew of leather, wood of like substance, cut from a strip or
'wire," and driven home by a driver When applying the invention to the
operation of soleing or welting, I support the boot or shoe on a horn or post
common to this class of machinery
66
To provide for the automatic regulation of the depth the piercing tool shall
penetrate the sole or insole, without the needle striking against the iron last,
when lasting, and piercing to the interior of the boot or shoe, when soleing or
welting, I mount upon the stem usually carrying the horn in this class of machine,
a "Jack or last holder of any ordinary description This stem is made capable
of the required latéral motion, to bring, in turn, every part of the last under
operation The stem is borne upwards by a spiral spring, to hold the boot or shoe
up to the nozzle of the rivetting head The head of the machine consists of a
framework in which is mounted, in bearings, a vertical spindle serving as a fulcrum
for a laterally swinging head carrying the piercing tool, the feed tube, and the
driver This head is moved laterally for the purpose of bringing these tools in
succession over the central line of a nozzle carried by the frame (a short distance
below the lower end of the sewinging head), by means of a pair of disc cams mounted
on a horizontal shaft carried by arms in connection with the swinging head
shaft may be driven in any convenient-manner
This
The piercing tool and the driver consist of rods mounted in socket bearings in
the swinging head, and having at their upper ends lateral projecting pins or blocks,
which take in the forked ends of a pair of horizontal rock levers fulcrummed on
the swinging frame, and having bowls at their rear ends which enter grooves in the
sides of the disc cams, to give the levers their up and down motion.

page_text: The cam operating the rock lever of the piercing tool is fitted with a wing at its
side, to form the operating groove This wing is capable of changing its position,
so as to give greater or less motion to the rock lever, and consequently to the
piercing tool
The position of this wing on the cam is automatically regulated, according to the
varying thickness or position of the work, in the following manner, when the horu
is used as a support for the work
Two horizontal rock levers are fulcrummed in the machine, one just below the
cams, and the other below the Journal of the horn The rear ends of the levers
are connected by a link The short end of the lower lever overlies a collar on the
stem, and the upper lever is provided with a movable arm carrying a bowl for
acting on the periphery of the wing on the cam
Thus, as the stem carrying the
last holder or horn is depressed by the varying thickness or position of the work,
the wing on the cam will be closed up, giving greater throw to the end of the lock
lever, and thereby to the piercing tool, and vice versa
When the last is used to support and carry the work, the upper rock lever only
will be required A pendent rod jointed to the forward end of this lever, carries
at its lower end a finger, which beais on the upper (in the crease) of the boot, or
upon the insole, as the case may be, thereby regulating the stroke of the piercing
tool
To prevent the finger unduly pressing upon the upper, and to hold the lever
in position while the pin is being driven, a wedge block is brought under the rear
end of the lever by a spring, and when the pin is diven in, the wedge block 15
withdrawn by the action of an incline on one of the cams
The feed tube is fitted with an arrangement of levers operated from the
projecting pin at the upper end of the piercing tool, to press on, and push out, a
portion of the strip of leather passing down its hollow stem,--spring retaining fingers
preventing its subsequent withdrawal
A knife is provided to cut off the requied portion to form a rivet
This portion,
as soon as it is pushed out, is seized by a pair of fingers between the nozzle and
the lower end of the swinging head, and held until, by the automatic action of the
cams upon the swinging head, the feed is laterally shifted, and the driver brought
over the severed portion of material, which will then be driven out of the grip of
the receding fingers, into the hole formed in the insole to receive it thus securely
rivetting, or screwing with a leather pin, the upper to the insole, without passing
entirely through the insole
The material from which the pins are formed, will in general be supplied to the
machine in the form of wire, but I may us a ribbon of wood or other material
the width of the longest pin, and sever a strip from the ribbon just before placing
it in the feed tube The cross-cutting knife will then, as before, cut it to the length
required for the thickness of the work at this time under operation

Improvements relating to the Manufacture of Boots and Shoes
I 1 HOMAS COW BLRN of Spring Villa, Brook Street, Gloucester in the County
of Gloucester, Engineer, 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
The object of this invention is to provide, in machine-made boots, for a smooth
insole, that is to say an insole which presents no projections in the shape of the

page_text: This
points of the brads or pegs which are used in attaching the upper to the insole, as
is usually the case in machine-made boots and shoes, and is obviously a great
objection to this class of boot, and a source of discomfort to the wearer
object is effected by causing the awl or piercer to pierce the insole to only part of
its thickness, and by providing pegs which are of such a length as to penetrate the
insole the same distance only as the piercer
It is well known that the thickness of the sole varies according to the part of the
boot, that is to say, the sole at the waist will be thinner than the sole at the ball of
the foot, and consequently the piercer must penetrate a less depth, and the pegs
must be shorter for one part of the sole than for another, and I therefore provide
means whereby the movement of the piercer and the length of the peg will be
regulated as required

The same letters of reference will apply to corresponding parts in all the
figures
In carrying out this invention with respect to lasting, I place the upper of the
boot or shoe on an iron last carried in the machine by a jack or holder, as usual,
and as each portion of the upper is pulled over the last by hand, I secure it to the
insole by automatically piercing a hole through the upper and into the insole, and
placing therein a pin or peg of leather, wood, or like substance, cut from a strip or
66 wire," and driven home by a driver When applying the invention to the
operation of soleing or welting, I support the boot or shoe on a horn or post common
to this class of machinery.
To provide for the automatic regulation of the depth the piercing tool shall

page_text: penetrate the sole or insole without the needle striking against the iron last, when
lasting, and piercing to the interior of the boot or shoe, when soleing or welting
I mount upon the stem usually carrying the horn in this class of machine, a "Jack
or last holder of any ordinary description This stem is made capable of the
required lateral motion, to bring, in turn, every part of the last under operation
The stem is borne upward by a spiral spring, to hold the boot or shoe up to the
nozzle of the rivetting bead The head of the machine consists of a frame-work
in which is mounted, in bearings, a vertical spindle serving as a fulcrum for a
laterally swinging head carrying the piercing tool, the feed tube, and the driver
This swinging head is moved laterally for the purpose of bringing these tools in
succession over the central line of a nozzle carried by the frame (a short distance
below the lower end of the swinging head) by means of a pair of disc cams mounted
on a horizontal shaft carried by a bracket from the fixed head
This shaft may be
driven in any convenient manner
The piercing tool and the driver consist of rods mounted in sochet bearings in
the swinging head, and having, at their upper ends, lateral projecting pins or
blocks which take in the forked ends of a pair of horizontal rock levers fulcrummed
on the swinging frame, and having bowls at their rear ends which enter grooves in
the sides of the disc cams, to give the levers their up and down motion
The cam operating the rock lever of the piercing tool is fitted with a wing at
its side to form the operating groove This wing is capable of changing its
position, so as to give greater or less motion to the rock lever, and consequently to
the piercing tool
The position of this wing on the cam is automatically regulated according to the
varying thickness or position of the work, in the following manner, when the horn
is used as a support for the work
Two horizontal rock levers are fulcrummed in the machine, one just below the
cams, and the other below the Journal of the horn The rear ends of the levers
are connected by a link The short end of the lower lever enters the groove of a
collar on the stem, and the upper lever is provided with a movable arm carrying a
bowl for acting on the periphery of the wing on the cam Thus, as the stem
carrying the last holder or born is depressed by the varying thickness or position
of the work, the wing on the cam will be closed up, giving greater throw to the
end of the rock lever, and thereby to the piercing tool, and vice versa
When the last 18 used to support and carry the work, the upper rock lever only
will be required A pendent rod jointed to the forward end of this lever carries,
at its lower end, a finger which bears on the upper (in the crease) of the boot, or
upon the insole, as the case may be, thereby regulating the stroke of the piercing
To prevent the finger unduly pressing upon the upper, and to hold the lever
in position while the piercer is being driven, a wedge block is brought under the
rear end of the lever by a spring, and when the pin is driven in, the edge block
18 withdrawn by the action of an incline on one of the cams
tool
The feed tube is fitted with an arrangement of tappets operated from a pro-
Jecting pin or lug at the upper end of the piercing tool. The "wire' of leather or
wood from which the pin is to be made, passes down the feed tube, and is caught
near the bottom by two gripp ng fingers, one of which is stationary, and the other
moves with the tube This finger presses on and carries down with the tube a
portion of the strip of leather, the stationary retaining finger preventing its
subsequent withdrawal
This
A knife is provided to cut off the required portion to form a rivet
portion, as soon as it is pushed out, 18 seized by a pair of fingers between the
nozzle and the lower end of the swinging head, and held until, by the automatio
action of the cams upon the swinging head, the feed is laterally shuted, and the
driver brought over the severed portion of material, which will then be driven out
of the grip of the fingers into the hole formed in the insole to receive it, thus
securely rivetting or securing with a wood or leather pin the upper o the insole,
without passing entirely through the insole

page_text: The material from which the pins are formed, will in general be supplied to the
machine in the form of "wire," as before mentioned, but I may use a ribbon of
wood or other material the width of the longest pin, and sever a strip from the
ribbon just before placing it in the feed tube The cross-cutting knife will then,
as before, cut it to the length required for the thickness of the work at this time
under operation
Referring now to the drawings,
A is a standard, which rises from a suitable base or foundation (not shown), and
carries at its upper end the mechanisms which form the principal features of the
present invention About midway of its height, the standard A is formed with a
bracket A, provided with a bearing in which slides a vertical rod or spindle B
carrying the post or horn B₁, or, it may be, a jack for a last.
This rod B is
kept in a raised position by a spring B2, and is provided with a
circumferentially grooved collar or sleeve B³, in the groove of which works the
forked arm of a lever C
This lever C is connected by the rod C¹ with part of the mechanism of the head,
as will be presently more fully described
A is the head, extending from the standard A, and having bracket bear-
ings A* A**, for the vertical spindle D Mounted upon this spindle D is a
swinging frame E, which consists of two arms connected by a plate, in which are
formed three vertical recesses
Extending upwards from the head A², are brackets A³ A³, in which are the
bearings for a cam shaft F, which is also the driving shaft
Standing up from the back of the swinging frame E, are lugs E', which carry 10
bearings an axle on which forked levers & G¹ are mounted G are bowls carried
by the levers G G₁ and set at a slight angle, as seen in Fig 3
These bowls G'
enter the groove of one or other of the cams H H (which I designate the driver
cam and the piercer cam respectively) on the shaft F, as the frame E is swung to
one side or the other, the action of the cams being to rock the levers on their
pivots, to operate the respective piercing and driving tools or instruments
This swinging motion is effected automatically by means of the bowls J, which
are carried by brackets Es extending upwards from the frame E, and run in contact
with the edge of the cams H H¹ These cams are so adjusted that a full portion
of one cam will be opposite one bowl, when a cut-away portion of the other cam is
opposite the other bowl, and in this way the frame is swung to the right or left
at the desired moment, to bring one of the bowls G³ into the groove of its own
cam H or H¹
When the frame is in a central position, the levers G G¹ are held up out of
action by means of a fixed curved finger K, which will overhe the tail end of the
levers, as seen at Figs 2 and 3
The swinging frame E is formed to receive three rods, which represent respec-
tively a driver X, a feeder Y, and a piercer Z The rod or driver X is pivotted
to a block G, which slides in the fork of the lever G, while the rod Z is pivotted
to a block G*í, which slides in the fork of the lever G', as seen in Figs 2 & 4,
and these rods are depressed, according as the bowl G of the particular lever G
or G is in the groove of the driver cam H or the piercer cam H', to drive in
the peg, or to pierce the material with the awl, as will be hereafter more fully
described
The piercer will consist of a pointed instrument of the proper size, fitted into the
end of the bar or rod Z, after the manner of a needle in the needle bar of a sewing
machine, or in any other convenient manner, and the driver, which will be fitted in
like manner to the bar or rod X, will consist of a blunt instrument of the same
diameter as the piercer
The feed mechanism which is intended to feed forward the "wire
wood to form the peg or rivet, will now be described
"of leather or
The feeder Y consists of a round bar or rod, which is slotted or grooved as
shown at, Figs. 3, 5, 6, and 7, from end to end, to receive the wire
The wire W

page_text: passes in at one end of the slot or groove, and out at the other end
ра
Near the
lower end of the bar Y are two projecting lugs, between which is pivotted a
gripping finger a held n position by a spring The end of this anger enters the
slot in the bar, and, under the influence of the spring, presses on the wire W,
holding it to the rod Y with sufficient force to draw forward a supply from a reel
or other holder, when the feeder rod moves down A portion of wire will thus be
forced out beyond the swinging frame E, to be utilized in the manner hereinafter
described The swinging frame E is also slotted at z, to correspond with the slot
in the bai Y, and projecting into this slot is a gripping tinge b carried by lugs on
the face of the swinging frame The end of this gripping finger under the
influence of & spring, presses on the wire W at a point below the end of the
feed rod at its lowest position, and Jams it against the swing ng frame, so
that the wire will not be drawn back by the upward retuin motion of the feed
rod Y
At the upper end of the feeder rod Y, are two adju table tappets & and ',
between which projects a bracket arm, pin or lug c secured on the top of the
piercer rod Z
When the lever G', operating the piercer rod Z, is descen ling from
the position of Fig 6 to the position shown at Fig 7 the arm c after an amount
of lost motion, will strike the lower tappet d and carry down the feeder rod Y, and
with it the wire, as shown at Fig 7 On the return movement of the lever G¹
the arm c, as it nears the extent of its upward motion, will strike the tappet d',
carrying up with it the feeder rod Y, its gripping finger a slipping over the wire,
which is retained by the action of the gripping finger b On the feed rod attaining
its highest position (Fig 6), the gripping finger a will take hold of the wire at a
higher point, so that a fresh portion of the wire will be drawn from the supply into
the feed rod w th the next downward movement of the rod Y
When the portion of the "wire 15 thus pushed out from the swinging frame E,
which will then be at the central position of its movement, it is seized by a pair of
guppers L L (see Figs 1,2 8, and 9), which, at their gripping edges, are formed
to interlock The exact form of the grippers L L 18 clearly shown in the detail
Figures 84, 88, 8, which are respectively a side view and plan view of the grippers
open, and a plan view of the grippers closed These grippers L L' are keyed on
axles mounted in bearings in curved brackets A projecting from the head A³, and
round the swinging frame L On one axle of each jaw is keved an arm L* I 3, which
arms are connected togetner by a link I * To the arm L³ 18 pivotted the rod L.,
which is connected by a link L' to the bracket A³ so as to ensure a more or less
parallel movement of the rod L' This rod carries, at its upper end, a bowl L',
which runs in contact with the edge of a cam M (see Fig 4) mounted on the shaft k
To the outer end of the arm L is attached a spring Le, the action of which is to
close the grippers, and keep the bowl L' in contact with the cam M
The grippers are shown open in Fig 1 and closed in Fig 8, though the open
position is also shown in dotted lines in this figure
When the projecting
66 wire is hrmly held by the guppers, a knife blade N 18
brought forward, to cut off the requisite length for the peg or rivet
This knife blade N (see Figs 1, 2, 8 and 9) may be mounted in suitable guides
attached to the bottom of the swinging frame E, and is operated (see Figs 1,
8, and 9) by the lever N, which is fulcrummed at N³, to the cover plate E* of the
frame E his lever is actuated by the cam projection N³ on the shaft F, through
the rod N, which works in a suitable guide, a spring No being provided to keep
the rounded end of this rod N* up to the cam
Another form of cutter mechanism, and one which it is preferred to use, 18
shown at Figs 13 and 13³, and consists of a horizontally reciprocating arm N
fulcrummed on a lug projecting from the side of the swinging frame E, and
carrying a knife blade N This arm reciprocated by the lever N', pivotted
on the side of the frame E, and operated by the cam on the shaft F, as before
described This form of knife will give a more shearing cut than the first
described, and is better suited to pegs of other materials thau leather \

page_text: When the peg has been cut off, the driver X is brought into position, and the
peg is forced down into the material through the nozzle or guide, O, against which
the material rests
I will now proceed to describe the mechanism for regulating the depth of piercing
and the length of the peg
The horn or post BI is kept up to the nozzle O by the spring B on the spindle B
(see Fig 1) It will be evident that, by placing thicknesses of material between the
horn and the nozzle, the horn will be pressed down more or less This movement
of the horn will depress the shorter arm of the forked lever C more or less, so as
to raise the longer arm and the connecting rod C¹, which will operate the regulating
mechanism
This
This mechanism consists of the curved lever P fulcrummed at P₁ to the head A²
Pivotted to this lever P, at P³, below the fulcrum P¹, is an upwardly projecting
curved arm Q, which carries at its upper end a bowl Q¹, and is held in position by
a curved radius bar P³, which is fulcrummed at P on the bracket A³
mechanism is used in combination with the piercer cam H³, which is provided with
a wing or adjustable cam surface H2 (see Figs 2, 10, and 12) This wing H2 1$
pivotted to the side of the cam H' and is held in its normal position, that is, away
from the cam shaft F by a spring H³ As the cam H¹ rotates, this wing will come-
into contact with the bowl Q1, and it will be evident that, if this bowl is raised by
the depression of the horn, the wing H³, as it comes round, will be pressed inwards
towards the shaft F of the cam H¹ The inner face of this wing H is the
actuating cam surface, against which the bowl G of the lever G works, and.
consequently the more the wing H is pushed in, the greater will be the rocking
motion given to the lever G, and the greater will be the movement of the piercer Z.
Thus, according to the thickness of material between the nozzle O and the horn B¹,
so will be the depth to which the piercer Z descends, and so will be the length of
the peg that is cut off, because the feed of the "wire" is regulated by the movement
of the piercer lever G³, as before explained
"
The cams H H are shown at Figs 10, 11, 12, and 13, Figs 10 and 11 being
inside views of the piercer cam H¹ and the driver cam H respectively, and Figs 12
and 13 corresponding edge views
The mechanism heretofore described is more particularly applicable for lasting,
that is to say, for tacking the upper to the insole, previous to rivetting on the sole,
but with slight modifications, the machine may be used for soling from the face or
tread of the sole, or from the welt side
I will now proceed to describe such modifications which are shown with reference
to Figs 14 and 15
In Figs 14, the rod C¹ is connected to a lever R, which has its fulcrum at R' on
the head A At one end, this lever is held up by a spring R² On the other side
of the fulcrum, this lever is formed with a short arm R and a long arm R* To
the short arm R³ is pivotted the bent rod S, provided with a lateral projection S',
which presses during working in the crease of the boot, as shown, the boot being
carried on the last In the figure, four thicknesses of sole leather are shown, but
these thicknesses will, in some parts, be pared away, and thus the total thickness
will be less, consequently, the last being pressed upwards by the spring B³ (Fig 1),
the position of the crease will be higher
The rod S will thus be raised, which will rock the lever, the rod C¹ will be
drawn down, and the regulating bowl Q' will be withdrawn from the path of the
winged cam H³, and the movement of the piercer Z and feeder Y will be
correspondingly reduced
During the piercing operation, it is necessary that the lever R and its accessories
shall be held firmly or rigid, and for this purpose I form the underside of the lever R
with an inclined face, and I adapt underneath it a wedge T, which is operated
against the pressure of a spring T¹ by the lever T This lever Tis rocked by
means of the pin T3 carried by the piercer cam H, or by a disc on the cam axle F
To the longer arm R' of the lever R, is pivotted a rod S', which bears upon the

page_text: This
insole, and serves to regulate the depth to which the piercer operates when it is
desired to secure the upper to the insole, as in the operation of lasting
operation is more clearly shown on the diagram Fig 14ª
In Fig 15, the mode of securing the sole to the welt is shown the boot being
carried by a horn or post In this arrangement, I provide a gauge S', which
I secure to the point of the post, and this gauge ensures the row of holes which
are pierced, and the pegs which are inserted, al vavs being at a regular distance
from the edge of the sole
When a strip of wood or other material is used from which the peg is cut prior
to being driven, I provide an additional knife, and the swinging frame is arranged
as shown in Figs 16 to 20 The swinging frame E and the feed rod Y (which in
this case does not reciprocate) are slotted in a diagonal direction as shown at 1,
Figs 17, 18, and 19, for the entrance of the strip, and I slot the swinging frame
and the feed bar at right angles to the slot 1, and in a diagonal direction to receive
an additional knife m On the opposite side of the centre line of the feed bar Y
and also in the swinging frame, I form a splayed out slot as clearly seen in the
enlarged section Fig 19 (which I will call the ejecting slot l¹)
The strip of wood represented by n passes brst between a fixed pair of spring
grippers n', and then though a second pair of grippers n² (carried on lugs of the
swinging frame) into the slot of the frame L and the feed bai o is a fixed stop
against which a button on the end of the knite m strikes, as the frame E swing
The knife m consists of two parts, namely, a cutting blade and a stop plate m',
which lie side by side The stop plate is formed, as shown at Fig 20, with a
recessed portion, and the peg, when it is cut off from the strip by the cutting blade,
will be always the same size, and in its length will extend partly across the recess
Passing down through the hollow feed bar Y, is a rod Y', provided at its upper
end with a pair of adjustable tippets d d¹, and between these tappets projects the
bracket c, carried by the piercer rod or forked lever G', like that previously
described
When the feeder rod Y¹ descends, the peg will be driven into and between the
grippers L 1, and is cut off the correct length by the kn fe N, as before The
extra portion of the peg which is cut off the knife N will remain behind, and it is
pushed through the recess by the advancing strip n into the ejecting slot l', from
which it falls to the ground or into a suitably placed receptacle
The action will be as follows
The swinging frame E is brought into the position shown at Fig 18, that is to
say, the piercer Z 18 in the position to pierce the material At the same time, the
knife head strikes against the stop o, and the knife is driven forward, to cut off
the peg transversely from the strip The frame E is then swung to bring the
feed Y into the central position, and, by means of feeder rod Y', operated as above
described, the peg is driven down and seized by the grippers, the peg being cut to
its proper length by the knife N, as before The frame is next swung into the
dotted position Fig 18, so that the driver X 18 brought into position, and the peg
is driven into the work The swinging of the frame will feed the strip n forward
against the stop plate, and thus a fresh portion of the strip will be presented to
the cutting blade The frame is now awung back again, to bring the piercei Z
into position, and to cut off the peg, when the operation is repeated as before
I will now proceed to describe generally the action of the machine Let it be
supposed it is desired to attach the upper to the insole in the lasting operation, and
the material is between the nozzle and the last on the jack Motion is com-
municated to the cam shaft F in any convenient manner The mode of driving
forms no part of the present invention, and beyond the indication that it is
preferred the ariving mechanism shall be thrown in and out of gear by a treadle
movement, no description is necessary
The rotation of the cams H H¹ (which are properly set for the purpose) will
swing the frame E by means of the bowls J which beat against the peripheries of
the cams.

page_text: Let it be supposed that the frame E 18 swung to the right, to bring the piercer Z
into position, as in Fig 18, the bowl G³ of the lever GT will be in the groove of
the cam H The form of the groove will depend upon the position of the wing H³,
which is regulated by the thickness of material between the nozzle O and the horn
or last, through the parts C³, P, Q, Q', as before indicated
The
According to the position of the wing H³, so the movement of the lever G³ will
be greater or less, and the piercer Z will pierce to a greater or less depth
swinging frame will be stationary, while the operations of piercing, feeding, and
driving, are taking place, the arresting of the movement being due to the form of
the cams
"
"
The piercer Z being withdrawn, the frame E swings to the left, to bring the
feeder Yinto the position shown at Fig 3 The feed of the " wire into the teeth
of the grippers L L' then takes place, and the " wire Is cut off the exact length
required by the knife N The frame E is now swung further to the left, to bring
the driver X into position, and, at the same time, the bowl G³ of the lever G
enters the groove of its cam H As the cam H rotates, the lever Gr is rocked on
its pivot, and the driver X is forced down, to drive the peg (which is held by the
grippers L L') into the hole that has been made by the piercer Z
As the peg 1s
always cut off to the exact length required, whatever it may be, and the difference
in the depth to which it is to be driven is therefore provided for, the amount of
movement given to the driver X is always the same
As soon as the driver X has effected its purpose, and is withdrawn, the
grippers L L' are opened, the swinging frame E is again swung to the right, and
the operations of piercing, feeding, cutting off, and driving, proceed as before
A feed foot of the usual kind will be provided to shift the work along, when
soleing or welting
I would here remark that although this invention is specially intended for use in
the manufacture of boots and shoes, it will be obvious that it may also be used för
securing together the ends of leather and other belting, and for similar purposes,
and I wish it to be understood that these uses are to be considered as being
covered by the following claims, notwithstanding any apparently restrictive words.
Having now particularly described & ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
