Improvements in Machines for Operating upon the Soles of Boots
and Shoes during Manufacture.
[A communication from abroad by THE 'INTERNATIONAL GOODYEAR SHOE
MACHINERY COMPANY, of Boston, Massachusetts, United States of America.]
I, JAMES GRIEVE LORRAIN, M.I.E.E., M.I.Mech. E, of Norfolk House, Victoria
Embankment, London, in the County of Middlesex, England, Chartered Patent
Agent, do hereby declare the nature of this invention, as communicated to me, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The present invention relates generally to improvements in machines of the
above class, and more particularly to improvements in machines for attaching the
heel seat of the sole to the lasted upper and insole and rounding or trimming
the projecting edge to conform substantially to the form of the last. To the above
end the present invention consists of a tool or driver arranged to operate upon the
bottom of the sole, a trimming knife arranged to operate upon the edge portion of
the sole, connected mechanisms for actuating the tool and knife, and means under
the control of the operator for throwing the tool out of operation during the
operation of the knife. The present invention further consists of an improved
gauge or guide formed and arranged to bear upon the lasted upper against the
counter, and to guide the shoe while turned to pass the gauge around the back of
the last and present the heel seat to the tool and knife. The present invention
further consists of certain new and improved devices and combinations of devices,
and improvements in certain details of mechanism hereinafter more particularly
set forth and claimed. While the machine of the present specification is designed
for the purpose of nailing and trimming heel seats upon a lasted shoe and is
hereinafter termed a 'heel seat nailing and trimming machine," I consider that
the present invention is not limited to the specific adaptation described, as several
features thereof could readily be adapted to "Rough Rounding and Channelling
Machines and other forms of Sole machines without any departure from the
present invention.

In the drawings A represents a frame or head suitable to support the working
parts of the machine, and conveniently mounted upon a suitable post or pedestal A
While I do not consider the present invention as limited to any specific form of
nailing mechanism, since any of the well known forms of loose nailer, or continuous
wire nailer, may be with slight modifications adapted to operate in connection with
the mechanism hereinafter described and good results secured, yet in order that
one skilled in the art may be able to thoroughly understand the nature of the
present invention and easily construct a machine embodying the same, I will now
describe a form of continuous wire nailer which I have adopted in practice, and
have simplified and improved.
In the drawings D represents a driver, which is secured to the driver bar d,
which is supported in suitable bearings on the head A in which it is free to
reciprocate vertically. The driver bar d carries a cam block d' which is engaged
by a cam da the form and arrangement of which will be more fully hereinafter
described. The driver bar d is projected above the head A, its upper end being
in contact with the driving lever d³ in the usual manner.
The driving lever d³ may be and conveniently is of the usual form consisting
of a substantially straight lever fulcrumed at d' upon the head A, or suitable
uprights thereon. The front end of lever d³ rests upon the driving bar d, and
the opposite end upon a rod d³, free to reciprocate vertically, and supported and
guided in suitable bearings in the head A. A spring do is provided which bears
against a nut or stop d', and acts to keep the rod d in its raised position. "The
above described arrangement is such that the driver bar d is raised by the action
of the cam da raising the front end of the lever d³ and depressing rod d³ against
the action of the spring do. The cam d² is formed with an abrupt pitch to allow
the block d¹ to drop quickly, so that sufficient momentum is given to the driver
bar d and driver D, by the action of the spring de to drive the nail, which is fed
into the throat 18 as hereinafter described.
The reference letter c represents a stationary cutter suitably secured to the
head A, and c¹ represents a movable cutter, arranged to co-operate with the
cutter c to cut the nails from the wire 2, and carried by the horizontally recipro-
cating carrier, mounted in suitable ways on the head A. The carrier c² may
be conveniently actuated by a bent lever c', fulcrumed at c on the head A, one
arm of the lever c being pivotally connected with a slide block c6, mounted in
transverse ways upon the carrier c, and the other arm carrying a cam roll working
in path cam c, the form and arrangement of which will be hereinafter more fully
described.
The cutter is conveniently provided with a perforation 8 in line with the
driver D, (as shown by dotted lines in Figures 2 and 3) and the cutter c¹ with a
perforation adjacent to its cutting edge, below the cutter c¹ is a stationary plate
or guard clo, preferably formed upon the head A, which is perforated at c¹ in line
with the driver D and with the bore of the throat c¹³.
The above described arrangement is such that when a nail has been severed from
the wire 2 by the action of the cutters, it falls into the perforation in the

page_text: cutter c', and is carried by the further movement thereof along the plate co, until
the perforations 8, 9, cl register with each other and with the bore of the
throat c, when the driver D descends and drives the nail.
All the above described devices, in substantially the form shown, are old and
well known in the art in several forms of continuous wire nailers, and a further
description thereof is regarded as unnecessary herein. I may say, however, that
the cams d³ and c7, for actuating the driver bar d, and the lever c, are conveniently
enclosed in a casing a, through which extends the driving bar d, and which is
provided with a removable front plate a¹, an arrangement which is also common
in prior forms of continuous wire nailers.
I will now describe the devices shown in the drawings for feeding the wire 2 to
the cutters c and c', and which involve several improvements over the prior art.
The wire 2 is carried upon a reel 3 mounted in the usual manner upon the
head A, from the reel 3 the wire 2 extends (preferably through suitable apertures
in the casing a) between a pair of corrugated feed wheels e and e¹. The feed
wheel e is arranged to be positively rotated, being mounted upon and rotating with
a shaft, supported in suitable bearings in the head A, and actuated as hereinafter
described.
The feed wheel e' as shown is an idler, and is arranged to be moved laterally
toward and away from the feed wheel e to regulate the pressure of the feed wheels
upon the wire. While I am aware that it has been heretofore proposed to provide
in a continuous wire nailer a pair of corrugated feed wheels, one of which is
laterally movable to regulate the pressure upon the wire, I consider, nevertheless,
that I have invented a new mechanism for securing the above suggested lateral
movement of the feed wheel which I will now describe.
The wheel e is mounted upon a trunnion e eccentrically projected from a
hub e, mounted and free to rotate in suitable bearings in the removable front
plate a¹. The above described arrangement being such that a rotation of the
hub e, in one direction, moves the trunnion and wheel e¹ mounted thereon
toward the wheel e, and a rotation of the hub e', in an opposite direction, moves
the wheel e away from the wheel e. In practice I provide the hub e' with an
operating levere, to which is conveniently secured a segmental rod e", which is
projected through a clamp e', by means of which the lever e5 may be locked in any
desired position. The advantage which I claim for the above described construc-
tion over the prior art is its extreme simplicity and the ease, accuracy and rapidity
of its operation.
The feed wheel e is actuated by the following described mechanism: -Fulcrumed
upon the head A, or a suitable bracket a secured thereon, is a bent lever F, one
arm of which carries a cam roll working in the path cam c, and the other arm
is pivotally secured to a swinging link f, also fulcrumed upon the head A.
Provision is made for the relative movement of the lever F and link f by a slot 5
in the lever F, which receives a pin 5* upon the link f, or a projection 6
therefrom.
In the link is provided a circular adjustment way f¹, in which works a slide f
movable along the same, and which may be clamped in any desired position therein
by a nut, or other suitable clamping means. The slide is connected by the
pivotted connecting rod f³, with the outer casing of the frictional ratchet F1,
which is mounted upon and rotates with the shaft e³.
turn
As shown in the drawing the ratchet F1 (Figure 9) comprises an annular
casing f, surrounding and fitted to a central block or disk f, and free to
thereon. In the annular casing, f' are formed a series of inclined recesses 8, 8, 8, 8
etc. in each of which works a roll 9, which is acted upon by a spring 10, which
acts to force it toward the contracted portion of the recess 8. The above described
arrangement is such that a rotation of the casing f*, in one direction, pinches the
rolls 9, 9 etc. between the casing f and disk f5, and causes the disk f to rotate
with the casing f. while when the casing f is rotated in an opposite direction, it
turns freely over the disk f5, which does not rotate therewith.

page_text: The operation of my improved wire feeding mechanism 18
follows:
described 38
The rotation of the cam e imparts a swinging motion to the lever F, which in
turn imparts a swinging motion to the link f, which by means of the connecting
rod fimparts an oscillatory motion to the casing f of the ratchet F¹.
When moved in one direction the casing f' carries with it the disk f, and causes
a partial rotation of the shaft e², which is communicated to the feed wheel e
mounted thereon, causing the wire 2 to be advanced toward the cutters c and c¹
between the feed wheels e and e¹. When the casing f is moved in an opposite
direction, as above stated, it moves loosely over the disk f, so that a reverse
movement of thic ratchet produces no rotation of the shaft c or wheel e, and
consequently no movement of the wire 2.
The extent of the movement of the wire 2 at each oscillation of the casing f³,
and consequently the length of the nail formed by the machine, is readily regulated
by moving the slide 2 along the slide way fl in the lever f, and clamping it in
the required position to give the desired length of nail.
I may say in this connection that while I do not claim to be the inventor of a
frictional ratchet, yet I have so combined the same with the devices herein before
described in this specification and hereinafter designated in the claims, that I
secure thereby a series of positive movements of the feed wheel, of uniform
extent, without the complicated devices shown in the prior art to prevent lost
motion, and I further provide a simple and convenient adjusting device, whereby
the extent of the movement of the feed wheel may be regulated.
I will now describe in detail the form of trimming mechanism shown in the
drawings.
H represents a cutter plate, the function of which is to support the edge of the
heel seat under the action of the trimming knife, and which may be provided with
the usual throat to receive the knife or with a cutter block h, of soft metal or
other suitable material, which will not dull the knife.
h¹ represents the work gauge, which as shown in the drawings forms the outer
end of the cutter plate H, being rigidly secured to or made integral with the
cutter plate.
A preferred form of the gauge k¹ is shown in Figures 7 and 8, but in regard to
the same it is only necessary to say that the gauge is so formed and held in
such position that it will bear upon the lasted upper against the counter, and guide
the shoe, which being turned to pass the gauge around the back of the last, to
insure the proper presentation of the heel seat to the nailing and trimming
devices. The gauge may be supported otherwise than by the cutter plate H.
It will be noted that as shown in the drawings the gauge h¹ by bearing against
the lasted upper holds the cutter plate H in position under the edge of the sole,
not allowing it to extend to far under the heel seat (which before the operation of
the machine is not attached to the shoe) and preventing it also from being
withdrawn from under the edge in passing around the back of the heel seat.
In this connection I desire to say that I am aware of the several forms of
gauges or guides used upon sole sewing and rough rounding and channelling
machines, but such machines as heretofore constructed do not operate upon the
heel seat of a sole, nor are the gauges or guides thereon adapted to guide the shoe
while being turned upon its support to present the heel seat to the operating tools,
and in so far as I am informed of the art I consider myself the first to provide in a
sole machine a gauge formed and arranged to operate as above suggested.
The cutter plate H may be and conveniently is adjustable transversely to the
direction of the feed, a result which I secure in the form of my invention shown
in the drawings by the following device.
In the cutter plate H is formed an elongated bolt hole h³, through which
extends a bolt, projected through suitable bearings in the head A, or a
bracket projected therefrom. The outer portion of the bolt h³ is threaded and
is provided with a nut 4, the arrangement being such that by loosening the uut h

page_text: the plate I may be moved in or out, and by setting up the nut 4 the plate II' may
be clamped in any desired position. The function of the above described adjust-
ment is to determine the width of the edge left by the trimming device around the
heel seat. In practice I find it convenient to provide for a vertical adjustment
of the plate H to allow for soles of different thickness, a result which in the form
of my invention shown in the drawings I secure as follows.
The plate II rests upon a threaded bolt 6, which is supported in a córre-
spondingly threaded bearing in a bracket dependent from the head A. The
arrangement being such that by loosening nut 4, the outer end of the plate H,
which receives the work may be set at any desired height by means of the bolt h6.
During the operation of the nailing and trimming devices the projecting edge
of the heel seat rests upon the cutter plate H, and the shoe itself may be held
by the operator as during the operation of a sole sewing machine, I prefer how-
ever to provide a suitable support therefor, which in the form shown in the drawings
is described as follows.
'
L represents a suitable post or standard provided at its upper end with the
usual spindle 7, which is inserted in the spindle hole in the last. The post Lis
connected, by a universal joint , with the supporting standard ; which is
mounted and free to reciprocate in a suitable socket or sleeve 13, supported by
suitable supports projected from the pedestal A'. The standard 12 is elastically.
supported in the sleeve 3, conveniently as follows:-In the base of standard 12 is
formed a socket 14, which receives the spring 1, which is supported by a plate 16,
secured to the sleeve 13.
:
The standard is preferably polygonal in section to prevent rotation.
The above described arrangement is such that the spindle / may be inserted into
the spindle hole of the last, carrying the shoe to be operated upon, and the post L
and standard depressed against the action of spring 15, and the last swung into
position to bring the projecting edge of the heel seat upon the cutter plate H,
when the post L is allowed to rise and the sole of the shoe is firmly held by the
action of the spring against the throat c¹².
To prevent the displacement of the shoe by the action of the driver D, I have
provided a device whereby the standard 12 is locked in its raised position, as above
described, while the driver D is driving a nail, and released after the nail is driven
to permit the operation of the feed. A convenient form of the above suggested
device is described as follows: -
In a suitable guide way in the pedestal A¹, preferably in the supports of sleeve 13,
works a sliding block, fitted to an aperture in sleeve 13, and arranged to bear
against the standard 2. To the block is pivotted one arm of the toggle lever 18,
the other arm of which is pivotted at 19 to the pedestal A¹. The toggle 18 is
operated by a connecting rod 110, free to reciprocate vertically in suitable bearings
in brackets (omitted for the sake of clearness) on the head A and pedestal A¹ and
which carries near its upper end a cam roll which works in the path cam 11. The
cam is so formed and timed with reference to the other parts of the machine
that it operates, through the connecting rod 710, to straighten the toggle 18, and
advance the block to pinch the standard, and hold it firmly from vertical
movement while the driver D drives each nail, after each nail has been driven
the cam bends the toggle 18 and withdraws the block to release the standard 12,
leaving the post L free to be depressed against the action of the spring 16. The
rod is in practice provided with a draw joint and spring to take up any
excess of movement imparted thereto by the cam 11.
I will now describe a prefered, though by no means essential, form of trimming
knife and its actuating mechanism.
N represents the trimming knife which may be of any suitable form, but which
is preferably formed with a cutting edge having a substantially straight central
portion and inwardly bent ends substantially as shown in Figure 16. I prefer the
form of knife above suggested for the reason that it insures a smooth cut, but the
present invention is by no means limited thereto.

page_text: The trimming knife N is secured to the trimming knife lever n, conveniently
pivotted at n' to the head A or a suitable bracket thereon. In practice I find it
convenient to mount the knife N in a carrier 20, from which projects a rod 21,
which is fitted to a longitudinal socket 22 in the lever n, and movable along the
same being held in the desired position by means of a set screw 23, or otherwise
so to arrange the knife N that it is adjustable transversely to the feed. I also
find it convenient to arrange for a vertical adjustment of the knife in the carrier 20,
which I secure as follows:-In the front of the carrier 20 is formed a vertical
groove 25, one of the side walls of which is formed by a movable plate 26, which
is secured to the carrier 20 by means of the bolts 27, 27. The groove 25 receives
the knife N which is movable along the same may be clamped in any desired
position by setting up the bolts 27, 27.
I may say in this connection that by arranging both the cutter plate H and the
knife N to be adjusted transversely to the feed I can regulate the width of the
edge left around the heel seat and the position of the nails with reference to the
edge, a feature of considerable importance in machines of this class. The trimming
knife lever n is arranged to oscillate vertically conveniently by the following
mechanism-n* represents a connecting rod, which connects the knife lever n
with a crank on eccentric pin n², carried by the shaft n³, mounted and free to
rotate in suitable bearings in the head A, and driven by a gear nt, which meshes
with a gear n³, mounted and actuated as hereinafter described, the arrangement
being such that a rotation of gear n5, through the gear n, the shaft n³, the
crank n³, and the connecting rod n*, produces a vertical oscillation of the knife
lever n.
It will be noted that the plane of rotation of the crank n³, and the plane of
oscillation of the knife lever n are substantially at right angles to each other, and
in practice I arrange for said movements as follows:-
The lower end of the connecting rod n* is provided with a yoke 40, which
embraces a sleeve or collar 41, mounted and free to rotate upon a pin 42, extending
longitudinally along the lever n, and supported in the lugs 43, 43 thereon, (see a
Figures 6 and 11). On opposite sides of the sleeve 41 are formed the sockets 44, 44,
which are engaged by the pins 45, 45 upon the yoke 40. Each of the pins 45, 45
is threaded to engage a threaded bearing in the yoke 40, so that the pins 45, 45 can
be adjusted in the sockets 44, 44. The upper end of connecting rod n* carries
similar yoke 47, similarly connected by the pins 48, 48, with a collar or sleeve 49 3
upon the crank pin n².
While I do not consider a feed mechanism as essential to the successful operation
of the other features of my invention, I find in practice that more uniform results
can be secured therewith, and the operation of the machine is made easier for the
operator, I will therefore describe a prefered form of feed mechanism, and explain 4
its connection with other parts of the machine.
In the drawings P represents a feed awl, which is mounted upon a feed
lever P¹, which is supported upon a trunnion p, the upper end of which is fitted
to a socket 30 in the head A (see Fig. 4) and the lower end of which is held by a
pin (not shown), or other suitable means, in the horizontal arm of an angle 4
piece 31, dependent from the head A. The feed lever P¹ is free to rotate about
and reciprocate vertically along the trunnion p. The feed lever P¹ is conveniently
a bent or angle lever, one arm p¹ of which carries the feed awl P, the other arm p³
being connected by suitable connections with the arm p³, of the bent lever P³,
pivottally supported at its angle in the bracket 35 on the head A or other suitable 5
support. The arm p' of the bent lever Pª carries a cam roll working in the path
cam p5, the arrangement being such that a rotation of the cam p³ produces a
swinging movement of the lever P2, which produces a swinging movement of
the feed lever P¹, moving the awl P to and fro in a horizontal plane.
On that portion of the feed lever P¹ which surrounds the trunnion p, is formed 5
an annular groove to which is fitted a collar p', upon which is formed a lug or
arm p, which projects horizontally therefrom, and which is rigidly secured to a

page_text: verucally reciprocating bar p³, mounted in suitable bearings in the head A (see
Fig. 4). The bar pe carries a cam roll working in a path cam p10, and the above
described arrangement is such that a rotation of cam pio causes a vertical reciproca-
tion of the bar p³, and a corresponding movement of the lever P¹ along the
trunnion p, producing a vertical movement of the feed awl P. The united action
of cams p³ and p10 imparts to the awl P the movement of a four motion feed.
The length of the horizontal or feeding movement of the awl may be conveniently.
rendered adjustable as follows:-
In the arm p of the lever P¹ is formed an adjustment slot 90, to which is fitted
a slide 91 movable along the same, the slide 91 carries a pin 92 which extends
through a slot 93 in the arm p³ of the lever P. Clamping means 94 are provided
whereby the slide 91 may be clamped in any desired position along the slot 90.'
The pin 92 is movable along the slot 93 to allow for the relative movement of the
levers P1 and P2.
The cams po and 11 may be and conveniently are path cams, and formed upon
opposite faces of the disk 60. The cam p³ is conveniently a periphery cam formed
upon a disk 61.
In operating a heel seat nailing and trimming machine it is often required to
trim the heel seat further toward the toe than is necessary or proper to extend the
row of nails which secure it to the insole, for this reason I have found it convenient
to so arrange my nailing and trimming devices, that they may be controlled
independently of each other, a result which in the form of my invention shown in
the drawings I secure as follows:
The cams c and d², which actuate the nail driving, and wire feeding and cutting
mechanism, are both mounted upon and rotate with a shaft s, provided with
suitable bearings in the head A. The gear n³, which oscillates the trimming
knife N, the disk 60, upon which are formed the cams p10 and 7 which, respec-
tively, impart the vertical movement to the feed awl P and actuate the toggle 18
to pinch and release the standard 12, and the disk 61, on which is formed the
cam p5, which imparts the horizontal movement to the feed awl P, are all mounted
upon and rotate with the shaft r. As shown in the drawing the shaft is tubular
and surrounds the shaft s which extends through the same. The shafts and s
are free to rotate independently of each other.
The shafts r and s may be and conveniently are driven by a common pulley R,
which is mounted to turn loosely upon the outer shaft r, and held from movement
along the same by suitable collars (not shown) or other suitable means."
The shaft s may be connected with the pulley R to rotate therewith by means of
a clutch s¹, and the shaft r similarly connected by means of an independent
clutch r
The clutch s may be of any suitable form, that shown in the drawing being of
a well known type, consisting of a disk 70 secured to the hub of the pulley R and
having in its face a segmental slot (not shown), and a disk 71 secured to a sleeve 73,
splined to the shaft s, and free to slide along the same, the disk 71 carrying upon
its face a pin 72 in position to engage the slot in the disk 70. A spring 74 is
arranged to hold the members of the clutch s¹ in engagement. The clutch s may
be conveniently controlled by the following mechanism:
Fulcrumed at 75 on the pedestal A¹, or a suitable bracket 76 thereon, is a
laterally swinging lever s³, conveniently in position to be operated by the knee
of the operator. The lever is connected to and rotates with a connecting rod ³,
mounted in suitable bearings on the pedestal A¹ and head A. At or near its
upper end the rod ³ carries a gears, which meshes with a gear 5, on a short
haft, mounted in suitable bearings in a bracket 79 on the head A, or other
uitable support. From the shaft is projected an arm s7, the upper end of which
8 wedge shaped, and projects in the paths of a stud 8 on the sleeve 73. The
bove described arrangement is such that, as the sleeve 73 rotates, the stud 8,
oming in contact with the wedge shaped portion of the arm s', forces the sleeve 73
utward, disengaging the members of the clutch st. An outward motion of the

page_text: lever by means of rod 3, and, gears 4 and 5, rotates the shafts and tips the
arm s out of the path of the stud 8, and the members of the clutch s¹ are thrown
into engagement by the action of spring 74. A suitably placed spring 80 is
provided connected with the lever s² and pedestal A' which acts to keep the arm s
in the path of the stud 58.
The
The clutch may also be of any suitable construction, as shown in the drawings
it consists of a disk 81, splined to the shaft r, and movable along the same.
disk 81 has an inclined peripherial face 82, which engages a correspondingly
inclined portion 83 of the pulley R. The reference numeral 84 represents a sleeve,
which surrounds the shaft r, and is secured to the head A in such manner that it
does not rotate with the shaft r, and is held from motion along the same.
On the end of the sleeve 84 are formed a series of inclined projections or
wedges 85 (see Figures 14 and 15).
Between the sleeve 84 and the disk 81 is interposed a disk 86, mounted upon
and capable of rotation independently of the shaft r. The disk 86 is provided
with a series of radial ribs or projections 87 (see Fig. 10), which are adapted to
come in contact with the inclined, projections 85 upon the sleeve 84. The above
described arrangement being such that a rotation of the disk 86, in one direction,
by moving the radial ribs 87 over the inclined projections or wedges 85, forces the
disk 86 against the disk 81, and moves the disk 81 toward the pulley R, causing
the inclined face 82 to engage the inclined portion 83 of the pulley R, in such
manner that the disk 81 is frictionally held to rotate with the pulley R, causing a
rotation of the shaft r. When the disk 86 is rotated in an opposite direction the
ribs 87, being carried into the depressions in the end of sleeve 84, allow the
disks 86 and 81 to move away from the pulley R, and the inclined face 82 to
disengage itself from the inclined portion 83 of the pulley R. In practice I form
the peripherial face 82 of the disk 81 at such an angle to its axis that when the
disk 81 is released it will immediately disengage itself from pulley R.
The clutch may be conveniently controlled by the following mechanism :-
represents a treadle fulcrumed at r, and connected with a lever r, which is
connected by a pivotted connecting rod 6, with a swinging lever, fulcrumed
at on the head A. The lever is connected by a link with the periphery of
the disk 86. The above described arrangement is such that a depression of the
treadle, by means of the lever, and the connecting rod 6, depresses the lever r",
and by means of the link ro, rotates the disk 86 to engage the members of
clutch r¹:
A suitably placed spring 10 rotates the disk 86 in an opposite direction to
disengage the clutch . To the disk 81 is secured a cam 88, which when the
lever is raised by the action of the spring 10, comes in contact with the roll 89,
carried by the lever r, and acts as a bracket to prevent further rotation of the
shaft r, any other suitable form of brake may, however, be substituted therefor.
The operation of the several parts of my present invention has been fully
described in connection with the description of their form and arrangement. In
using a machine embodying the present invention as shown in the drawing, the
operator jacks the shoe on post L, by inserting the spindle in the spindle hole
of the last. The operator then depresses the post L, and brings the shoe under
the throat c, with the projecting edge of the heel seat over the cutter block H,
and the gauge bearing against the counter, he then allows the post L to rise
which clamps the sole against the throat cl. I may say in this connection that
the machine of the drawing is designed to follow the "Rough Rounder," so
called, which trims the forepart of the sole, and a portion of the shank, commonly
leaving the heel seat and a small portion of the shank adjacent thereto untrimmed.
For. the reason above stated the operation of the present machine commonly
commences a little forward of the heel seat at a point at which it is undesirable
to drive nails, and the operator, when he has adjusted the shoe upon the machine
as above stated, depresses the treadle 3 which engages the members of clutch r¹,
and (power being applied to pulley R) "sets in rotation the shaft r, which, as

page_text: before stated, actuates the work feeding and trimming devices, and those devices
are set in operation.
The operator supports the forepart of the shoe, and holds the shoe against the
gauge h¹, turning it as required to allow the feed awl P to present the edge to the
trimming knife N, the nailing mechanisms remaining at rest. When a point
upon the heel seat has been reached at which it is desirable to commence to drive
nails, the operator swings out the lever with his knee, and engages the members
of the clutch s¹, which, as before stated, sets in rotation the shaft s, which actuates
the wire feeding and cutting, and the driving mechanisms, and said mechanisms
are set in operation, and commence to drive a row of nails around the heel seat,
which nails are spaced by the length of the feed, that is each nail is driven at a
distance from the next preceding nail substantially equal to the length of the
horizontal movement of the feed awl P.
While holding out the lever 2 with his knee, the operator still keeps his foot
upon the treadle 3, holding the same in its depressed position, so that the nailing
and trimming devices are kept in simultaneous operation.
While the nailing and trimming devices are both in operation, as above described,
the operator holds the shoe against the gauge h¹, and turns the same as required,
allowing it to be carried along by the feed until the back of the heel has been
turned, and a point reached upon the opposite side of the sole at which it is
desirable to end the row of nails driven by the nailing mechanism. When the
point above described is reached the operator withdraws his knee, and allows the
lever to be swung in by the action of the spring 80, which brings the arms in
the path of the stud 8, disengaging the members of the clutch s¹, and stopping the
rotation of shafts and of the nailing mechanisms actuated thereby.
If necessary the operator still holds the treadle 73 in a depressed position, and
the work feeding and trimming mechanisms continue in operation until a point
is reached (where the Rough Rounding machine left off) beyond which it is
unnecessary to trim the sole, when the operator releases the treadle, and the
operation of all the operating devices ceases, and the shoe is removed and another -
adjusted.
Having thus described the form and arrangement of the several features of my
invention, and the method of their individual and united operation, I desire to say
that I do not consider the present invention as limited to the details of mechanism
hereinshown, since, in so far as I am advised of the state of the art it has never
been heretofore proposed to provide, in any form of Sole Machine, a device formed
and arranged to trim the heel seat of a sole, and I would further say that I am not
aware that it has ever been heretofore proposed in a sole machine to combine nailing
and trimming devices to operate upon any portion of the sole.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
