page_text: I OWEN ROBINSON of the Champion Sewing Machine Works Victoria Street
Kettering in the County of Northampton do hereby declare the nature of my
invention for "IMPROVEMENTS IN COMBINED HEELING PARING AND BREASTING
MACHINES FOR BOOTS AND SHOES" and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
Statement:
This Invention relates to improvements on Cutlan's well known Machine for
heeling boots and shoes and paring and breasting the heels.
The objects of my improvements are to increase the efficiency of the operating
parts and to facilitate the removal and replacement of the boot rest which requires
to be made to suit special forms and sizes of heels.
In Sheet I of the accompanying Drawings I have shown in front elevation a
Cutlan Machine modified according to my Invention and in Sheets II III IV and V
I have shown in detail the parts which I have improved with a view of attaining
the objects above mentioned."
A A Fig: 1 is the main framing of the machine B B is a rocking frame mounted
on centres carried by the main framing, and this rocking frame is formed with a
pair of guides for receiving a horizontal bar C to which the paring knife holder D
is fitted. A compound central guide rod C¹³ formed of two interlocking parts C¹ C*
and made fast to the cross bar C passes up through the head of the rocking frame
and has strung upon it a coiled spring C which puts a downward pressure upon
the bar for the purpose of holding the paring knife to its work.
One of the centres on which the rocking frame B is mounted is a hinged socket
piece E which is intended to carry the boot rest F and permit of its facile removal
and replacement to suit the. work in hand.-The other centre consists of the
plunger G which has an endway motion in the framing A for the purpose of
forcing home the nails or rivets by which the heel of the boot or shoe
to the sole.
secured
The knife for breasting the heel is carried by a horizontal reciprocating bar H
which moves in a guide H pivotted at one end to the main framing and supported
at its other end by links connected to the device which gives the advance and
retiring motions to the knife.
In Sheet II Fig: 2 is a plan view of the hinged socket E showing the boot rest
in place and overlaid by a shield which serves to carry a guide for controlling the
operation of the paring knife.
Fig: 3 is a side elevation of the same the boot rest being partly in section and
a portion of the shield being removed.
Fig: 4 is an end view of the boot rest with the shield in place and Fig: 5 is a
detail of a portion of the boot rest.
The hinged socket consists of two parts E E¹ the part E being screwed firmly
to the framing A and the part El being socketed at its end to receive the stem F
of the boot rest which fits tightly therein but admits of being readily withdrawn
for replacement by another boot rest a series of which all of different sizes is pro-
vided for each machine. The stem of the boot rest is made hollow to receive a
bollw rod F which carries the head F3 of the boot rest or that part which receives
the heel of the boot or shoe.-Enclosed within these tubular portions of the boot
rest is a coiled spring F which serves to thrust the head of the rest outwards and

page_text: retain it in that position until the pressure of the plunger causes the recession of
the head for the purpose of effecting the insertion of the nails in the heel The
hollow rod F is slotted longitudinally to receive a guiding pin f which is screwed
into the stem F and enters the slot of the rod F1-Fitted to the outer end of the
stem F and held in place by a radially slotted plate f¹ (see Fig: 5) are the
drivers which enter inclined holes drilled through the head F2 of the boot rest
to receive the nails for the boot beel and adjust themselves to the inclination, of
these holes.
In Fig 1 the boot to be heeled is shown in position on the boot rest and the
plunger G is shown in its forward position.-As the plunger in its advance puts
pressure upon the heel of the boot the head of the boot rest retained in position by
the pressure of the spring F3 will yield to that, pressure and allow the drivers f
which are stationary to take the inclination of the several holes in which they work
and put a direct-thrust on the nails contained in the head F thereby ensuring the
insertion of the nails in the heel in a direction corresponding to the direction of
the guiding holes in the head F³.
The next operation after the securing of the heel in place is the paring of the
heel. This is done by the paring knife mounted in the rocking frame B. I
have said that the knife holder D is fitted to a horizontal bar C which through
the pressure of a coiled spring at its back is caused to hold the paring knife
to its work. It is necessary however to control the knife as it is moved round
over the heel by the rocking of the frame B on its centres. To provide for
this the knife holder is fitted to bear upon a pattern surface or template which
is shaped to correspond with the form of boot beel required to be produced.―
This pattern surface is carried by a shield I, see Figures 2, 3, and 4 carried by a
yoke I which is hinged to the socket piece E¹.
This shield I overlies the boot rest F and leaves a sufficient space between it and-
the stem of the boot rest to allow of the insertion of the boot upper between them.
The object of hinging the yoke which carries the shield is to allow of the shield
being lifted to place and withdraw the work with facility. The use of this yoke
serves also another purpose inasmuch as it admits of the shield being divided longi-
tudinally into two parts and of the parts being hinged together by stringing them
on a pivot pin i made fast to the yoke.-By thus dividing the shield which carries
the template I provide for the template adapting itself to different sizes and forms
of boot rest. Another advantage I obtain is an endway adjustment of the shield.
This result I secure by threading the end of the pivot pin i and tapping the end
lugs of the hinge joint of the shield- is a divided former or template on which
a bowle of the knife holder D runs and is a second former or template made of
thin steel and secured at its ends to the forward end of the former. This elastic
piece embraces the upper of the boot and provides for the expansion or
contraction of the shield equally with the divided template Thus the shield is
ready to adapt itself to various forms and proportions of boot or shoe or rather of
boot or shoe rest.—The paring knife holder D carried by the sliding bar C is made
as heretofore of two parts D D' hinged together as shewn in the detached views at
Figures 6, 7, and 8 Sheet III Fig: 6 being a side view of the knife holder Fig: 7 a
front view and Fig: 8 an inverted plan view of the same.-The part D which
carries the knife d is formed on its underside near its ends with two smooth
bearing surfaces one of which is made adjustable as shown at d¹ and adjacent to
the other bearing surface is a guiding edge d2 as usual These smooth surfaces.bear
the one on a detachable template carried by the plunger and the other on the
elastic template i-The edge or projection on the underside of the knife holder
serves to enter the crease of the boot between the heel and the upper and thus
serve as a lateral guide for the knife.-The knife-holder is also provided with a
bowled carried by an adjustable bracket, d bolted to the part D. This bowle
bears upon the template i¹ and moving in advance of the knife serves to control
the angle of its cut.--The bracket carrying the bowle is made adjustable, for, this.

page_text: purpose. The part D¹ of the knife holder enters a slot in the sliding bar C and
carrying bowles d* receives the pressure of the bar C in a manner that will allow
of its rocking in the bar.-The piece D¹ is connected to the bar C by the pivot pin
of the bowles d entering the diagonal slot of a plate c made fast to the bar C.-
Thus as the guiding edge on the knife holder traverses the crease of the boot the
knife holder will be free to move laterally in correspondence with the deviation
from a vertical plane of the crease of the boot.-The blade d is adjustable as usual
in its holder and its edge is made to correspond to the profile of the heel to
be cut.
:
The central guide rod, the part C₁* of which is made fast to the horizontal
sliding bar C, has its upper part C¹ suspended from a cross pin c¹ carried by the
rolling fulcrum of a hand lever C³--This rolling fulcrum is slotted vertically to
receive the upper end of the guide rod and allow of its free play therein.
The rolling fulcrum is confined within metal straps C made fast to the rocking
frame. c is a pair of slotted plates which stand on either side of the head of the
rocking frame and are connected together below the head of the frame by a cross
piece which embraces the guide rod.-This cross piece underlying the head of the
rocking frame and surrounding the guide rod takes the pressure of the coiled
spring C Through the slots of the plates c' the ends of the cross pin c¹ project for
the purpose of pressing down the plates and thereby increasing the pressure of the
spring C' on the bar and consequently on the knife holder D and paring knife d
By reason of the guide rod C¹ C₁* being formed of two interlocking parts the cross
bar C is allowed to follow (under the pressure of the spring) the irregularities of
the templates without disturbing the hand lever C. When it is required to
release the knife from pressure after it has been moved over the work by the
rocking of the frame it is only necessary to throw over the hand lever C to the
dotted position of Fig 1 when the knife will be relieved of the pressure of
the spring and raised clear of the work the guide pin and its bar being lifted by
the pin carried upwards by the rolling fulcrum.
The arrangement for working the breasting knife is shewn in Sheet IV Fig 9
In these
being a side view of the device and Fig 10 a plan view of the same
Figures H is the knife holder and H¹ is a guide in which the knife holder slides
This guide is pivotted adjustably at its rear end by a pin h to the main framing
and at its forward end it is coupled to a pair of links h¹ which are supported by a
fulcrum pin h carried by a bracket from the main framing It is thus made
adjustable in order to vary as desired the level at which the knife would strike
the heel On this pin is loosely mounted a bell crank lever H2 one limb of which
carries a segment extension H³ its curve being struck from the pin h* This
segment piece H' forms a support for the knife holder and to it is pivotted a
link H which connects with the rear end of the knife holder H Pendent from
this crank lever is a rod H³ which connects with a pedal lever H° (see Fig 1) the
depression of which serves to advance the knife * into contact with the breast of
the heel The edge of this knife is shewn as concave in plan view to correspond
with the curved face of the waist of the boot and it is arched transversely to give
the hollow cut desired for breasting the heel This device for operating the knife
I employ in substitution for the racks and pinion heretofore used and in addition
to simplifying the mechanism I provide against the knife rising with its guide
under the stress put upon it and thereby producing bad or unequal work.
To provide a support for the loose or unattached heel when first brought into
position I pivot to the front of the knife holder a horizontal table H from one side
of which depends a curved arm k³ This arm bears against a pin h* carried by an
adjustable cheek made fast to one of the supporting links h¹ of the guide H.-
While the knife is in its backward position this pin h will by bearing on the
curved arm h³ retain the table in its horizontal position and thus enable it to
support the heel-When however the heel has been attached to the boot and the
knife is advanced to effect the breasting of the heel the table which in its horizontal

page_text: position stood near the plane of the knife will drop out of the way into the dotted
position of Fig: 9 leaving the knife free to advance and act upon the heel.-The
return of the knife to its back position will ensure the lifting of the table to the
drawn position of Fig: 9 ready to receive and support a fresh heel.
To enable the plunger to be operated by steam power and to stop automatically
so soon as the requisite pressure is put upon the boot heel for heeling I adopt the
arrangement shown in Sheet V where Fig: 11 is a front view of the driving
mechanism and Fig: 12 a side view of the same The plunger G which is free to
slide endwise in its bearing in the framing A is formed with a vertical loop to
receive a crank pin carried by a divided shaft G-This shaft and also the rear
end of the plunger is supported in an adjustable frame G³ which is itself carried by
two pairs of adjustable double flanged nuts g working on fixed screws projecting
from the side of the main framing A.
The divided shaft G¹ is fitted with an internal toothed wheel G³ into which
gears a pinion keyed on the driving shaft G which has its bearings in the frame G³
and is fitted with a belt pulley This pulley is loose on its shaft and secured to the
shaft by a feather is a sliding collar g'.-This sliding, collar carries a toothed
projection which when advanced towards the driving pulley will come within the
circuit of a corresponding projection on the side of the belt pulley which receives a
continuous rotary motion and thereby serves to lock that pulley to the driving
sbaft. Cut upon the inner edge of the periphery of the internal toothed whee! Ga
are two notches having an inclined side into which a sliding bar g³ projected by
the pressure of a coiled spring as they are alternately presented to the sliding bar.
This bar works in lugs on the frame G and carries a fork g³ which embraces the
grooved collar g¹ and transunits thereto the motions of the sliding bar. For
drawing back this bar free of the wheel G' a pedal (see Fig: 1) is provided which
through a connecting rod and a bell crank lever g pivotted to the bar g³ and
turning on a pin carried by the frame G³ serves to give a back motion to the bar.
When the sliding bar is thus withdrawn its back movement being facilitated by
the inclined side of the notch the fork g³ of the bar g' will by advancing the collar
towards the driving pulley lock that pulley on its shaft and cause the mechanism
to be set in action. The next throw of the crank pin will advance or draw back
the plunger as the case may be and as one or other of the notches of the wheel G³
is brought opposite the end of the sliding bar the bar will be free to advance under
the pressure of its spring and withdraw the driving tooth of the collar from contact
with the pulley. The result of this will be to stop the action of the crank shaft G¹
when the crank is at its dead centre and to lock the plunger in its acting or in its
normal position as the case may be.
The double flanged nuts g form the hubs of two pairs of spur pinions g*g* which
receive motion from a pair of worms 9 keyed to a vertical shaft G* having its
bearings in the frame G³. By giving axial motion to this shaft G4 through its
hand wheel G³ the frame G may be adjusted to suit the advance required to be
made by the plunger which advance will vary according to the depth of heel
intended to be applied to the boot or shoe.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is -
First-The means described for facilitating the application and removal of boot
rests from the machine.
Second-Fitting the socketed joint with a shield for carrying the former or
template by which the action of the paring knife is controlled as above described.
Third In combination with the templates carried by the shield and the plunger
the adjustable guides fitted to the paring knife holder for the purpose above set
forth.
Fourth-The means above described for fitting the paring knife to the rocking
frame.

page_text: Fifth The adjustable guide for carrying the breasting knife and determining
the line in which the knife shall advance and be maintained while in action.
Sixth The means described for adjusting the plunger to its work and for
stopping it automatically and locking it in its forward and back positions.
