Improvements in Heeling Machinery.
I, WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford, in
the County of Stafford, Engineer do hereby declare the nature of this invention to
be as follows:
This invention has for its object improvements in machinery for building and
attaching the heels of boots and shoes and may be made use of in machines which
attach only or which both build and attach whether such machines are constructed
for working by power or by hand.
One part of my invention consists in an improvement by which the heel may be
attached to the boot in any desired position relatively to the sole, that is to say,
either central and in line with the sole or a little to one side or the other of the
sole and at any desired angle with the centre line of the sole or straight line
passing through the centre of the toe and centre of the heel.
To accomplish this I carry the boot either upon a heel seat block, a last or other
convenient arrangement so that it can be moved sidewise and into any desired
angular position as well as forwards and backwards in relation to the heel which is
about to be attached.
The heel may be placed in a mould and the boot conveniently carried above it
upon a depending leg which leg may be moved backwards and forwards in a slide
in the direction of the length of the boot sole for convenience of putting on and
taking off the boot as well as for adjustment lengthwise of the boot to the heel.
The leg may also have another slide at right angles to the first by which the boot
may be set through a small distance sidewise in relation to the heel.
One of the slides which carry the leg has an arm extending backwards and
downwards in which is mounted an adjustable vee for receiving the heel portion of the
upper and a tongs or pair of nipping arms is provided to hold the sole in the desired
position. The tongs or nippers are furnished with a right and left adjustment so
that they can alternately be thrown from one side to the other to suit right and
left boots. The back end of the arm may be guided vertically in the machine
frame.
If desired the leg may be constructed to turn upon its vertical centre or upon some
centre near and the position of this centre may be adjustable adjustable stops being
provided to limit the extent of the turning movement. The vee and the tongs or
nipping arms may be carried by an arm depending from the upper part of the leg
and turn with it. Handles and regulating stops may be provided for setting and
opening the tongs and setting the leg.
Another part of my invention consists in an improvement in the devices which
drive the attaching nails (or nails which hold the heel on to the boot) by which an
equal amount of their points is clinched against the last or seat plate whatever may
be the variation in the thickness or height of the heels.
To secure this result the nail block of the device is mounted or carried on
springs or otherwise arranged so that it will yield to some extent to an extra thick
heel that is a heel of extra height while the drivers which drive home the nails
rise always to one height irrespective of the height of the heel. The seat plate
then being maintained or set in one position in reference to the drivers all nails of
one length will be clinched uniformly while if any heel be of extra height the heads
of the nails will be buried therein to that extra amount.

Improvements in Heeling Machinery.
I WILLIAM HENRY DORMAN of The Hawthorns, Newport Road Stafford in the
County of Stafford 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:-
This invention has for its object improvements in machinery for building and
attaching the heels of boots and shoes and may be made use of in machines
which attach only or which both build and attach whether such machines are
constructed for working by power or by hand.
One part of my invention consists in an improvement by which the heel may be
attached to the boot in any desired position relatively to the sole that is to say
either central and in line with the sole or a little to one side or the other of the
sole and at any desired angle with the central line of the sole or straight line
passing through the centre of the toe and centre of the heel.
To accomplish this I carry the boot either upon a heel seat block, a jointed last
or other convenient arrangement so that it can be moved sidewise and into any
desired angular position as well as forwards and backwards in relation to the heel
which is about to be attached.
The heel may be placed in a mould and the boot conveniently carried above it
upon a depending leg which leg may be moved backwards and forwards in a slide
in the direction of the length of the boot sole for convenience of putting on and
taking off the boot as well as for adjustment lengthwise of the boot to the heel.
The leg may also have another slide at right angles to the first by which the boot
may be set through a small distance sidewise in relation to the heel.
One of the slides which carry the leg has an arm extending backwards and
downwards in which is mounted an adjustable vee for receiving the heel portion of
the upper and a pair of guide levers or nipping arms with guide pieces at their
extremities and hereafter called the " tongs" is provided to hold the sole in the
desired position. The "
""
tongs
or nippers are furnished with a right and left
adjustment so that they can be alternately shifted from one side to the other to suit
right and left boots.
The back end of the arm may be guided vertically in the machine frame.
If desired the leg may be constructed to turn upon its vertical centre or upon
some centre near and the position of this centre may be adjustable in the line of
the length of the boot, adjustable stops being provided to limit the extent of the
turning movement.
The vee and the "
"
tongs or nipping arms may be carried by an arm depending
from the upper part of the leg and turn with it or the leg may carry a last.
Handles and regulating stops are provided for setting and opening the "tongs
and for setting the leg.
"
Another part of my invention consists in an improvement in the devices which
drive the attaching nails (or nails which hold the heel on to the boot) by which an
equal amount of their points is clinched against the last or seat plate notwithstanding
slight variations in the thickness or height of the heels.
To secure this result the nail block of the device is mounted or carried on
springs or otherwise arranged so that it will yield to some extent to an extra thick
heel, that is a heel of extra height, while the drivers which drive home the nails rise
always to one height irrespective of the height of the heel. The seat plate then
being maintained or set in one position in reference to the drivers all nails of one
length will be clinched uniformly while if any heel be of extra height, the heads of
the nails will be buried therein to that extra amount.
The general construction of the machine may be of a character similar to that
described in Specification of former Letters Patent granted to me No. 15540

page_text: A.D. 1891, and therein illustrated in Figs. 3, 4, 8, 9, 10, 11 and 12, but in some
cases I dispense with the automatic movement therein described for bringing the
boot down upon the heel and consequently do not then require the "slot y³" in the
"buffer link" "3" but I use a plain joint instead to connect the "buffer link" to
the "toggle to, ³."
My present invention is illustrated by the accompanying drawings in which,
Fig. 1. is a side view of a portion of the machine.
Fig. 2. is a front view of the same.
Figs. 3 and 4. are views of one form of attaching device.
Figs. 5 and 6 are views of another form of device.
Figs. 7, 8 and 9 are views shewing the last leg arranged to turn about a point
near its vertical centre.
Fig. 10 is a view shewing the "tongs."
Fig. 11 is a diagram shewing the position of the "tongs" and the boot
relatively to the heel.
A. is a portion of the main frame of the machine carrying a head frame a in
which is mounted, so as to be free to slide up and down vertically, a ram a¹.
From this ram depends the apparatus a' for carrying the boot a³ which can be
set up and down in the usual manner by means of a screw and hand wheel or
similar contrivance, or may be operated by the machine as described in the
before mentioned Specification No. 15540, A.D. 1891. The ram a¹ carries a
head at which, it is convenient to make removable and it is fitted with a set
screw a. The head at is formed with a cross slide a mounted upon which is
a hanger, a' made with a longitudinal slide way as to engage the slide a formed
on the upper end of the leg a which is provided with a changeable seat
plate a (shewn in dotted lines) fitting within the boot a³. By means of these
two slides at right angles to each other the boot may be set in any desired
position relatively to the attaching device B.
The hanger a carries a vee piece C. which receives the back portion of the
upper and carries also the "tongs "D which engages the sole of the boot preferably
in the neighbourhood of the waist the object of these being to retain the boot in
the desired position while the heel is being attached.
Formed upon the frame A is a guide a in which the lower end a¹ of the
hanger a may slide up and down. A stud c¹ projects horizontally from the
hanger and is bored at its outer end to receive the small stem c² (shewn in dotted
lines) of the vee piece C which can be set in and out in the direction of the length
of the boot by means of a nut c. Upon the stud c¹ slides a block d pivotted upon
which by pins d' d' is a pair of links d³ d' whose outer ends d d are jointed by
pins to a pair of levers d do forming the "tongs." This pair of levers is
mounted on an eccentric d¹¹ formed upon the lower end of a pin d¹ carried in the
stud c. The pin is provided with a handle d¹³ which can be moved to the right
or left so as to give movement to the eccentric. The outer ends dds of the
tongs
are formed to engage the sole or feather of the boot and a spring d¹ is
provided upon the stud e¹ which bears forward upon the block d so as to close the
outer ends of the "tongs" upon the boot sole. Movement of the handle d¹³ will,
through the eccentric d¹ give movement to the "tongs "about the pins d' d' as a
centre so as to throw the ends d¹ d¹ of the "tongs" and also the boot either to the
right or left as the case may be. Stop pins d in a quadrant d18 serve to regulate
the setting of the "tongs."
"
The lateral setting of the leg a¹0 is done by means of a handle a¹ and screw a¹
stop pegs in a plate a regulating the amount of the movement.
The "tongs" is opened for the removal or insertion of the boot by means of a
handle e which is mounted on a pin el carried in the hanger a and connected to the
block d by a link e so that a forward movement of the handle draws back the
block d compresses the spring d and opens the tongs.
The diagram Fig. 11. illustrates the positions of the boot and the "tongs"
relatively to the heel. The line x. x is the longitudinal horizontal centre line of

page_text: "
the machine also of the attaching device and of the heel to be attached. The heel
is shewn by a full line ³, a right boot by a full line 23 and a left boot by a dotted
line. The positions of the "tongs and the vee piece for the right boot &³ are
shewn in full lines and the positions of the "tongs" and the vee piece for the left
boot are shewn in dotted lines.
Figs. 7, 8, and 9 shew a construction with the last leg arranged to turn upon its
vertical centre or upon some centre near so as to vary the angle at which the heel is
attached to the boot. The removable head a' and the cross adjusting handle and
screw a¹ a¹ are constructed as already described but in place of the hanger a', a cross
sliding carriage f is provided and furnished with an adjustable vertical pivot about
which the last can be turned through a small distance in the following manner.
The pivot is formed upon a sliding nut f³ engaging a screw f' and guided in a
slideway formed in the carriage f. The screw flies horizontally in the
direction of the toe and heel of the last and can be revolved by the handle f' so as
to traverse the nut ³ and pivot f1 nearer to the toe or heel as desired. The
pivot is provided with a dic f7 which traverses a slideway / formed in a block f
which is supported against the under face of the carriage f by means of covers f10 f1
which are kept a little clear to allow of side movement of the block but end
movement of the block is prevented by the plates f12 f¹³ against which the curved
ends of the block bear. Set screws f16f17 limit the side movement of the
block and consequently the amount of turning movement of the last f². The last
has a longitudinal slide a' as before.
14
If the pivot f¹ is placed exactly over the vertical centre line of the last leg
any turning movement given to the latter will simply turn the heel portion of the
boot without moving it sidewise but if the pivot f is brought forward to the
position shewn in the drawing a turning movement of the last will in addition to
altering the angle as above throw the heel end of the boot over to the right or left
as the case may be relatively to the heel about to be attached.
The attaching device shewn in Figs. 3 and 4 and also at B in Figs. 1 and 2 is
carried upon the table g and is of a form suitable to be used for attaching a heel
built and loaded with attaching nails by the heel building machine described in the
before mentioned Specification No. 15540 A.D. 1891, and illustrated therein in
Figs. 1, 2, 5, 6 and 7. Such a heel g¹ with the attaching nails loaded therein is
placed with its mould g³ upon spring supported pistons provided in the block g³
and which support the mould and heel so as to keep the heads of the nails g² clear
of the device. Dowels 9' retain the mould in position. The block g³ is divided or
provided with a top plate 9' supported (on strong springs 98 buried in the block) at
a little distance above the block and opposite each attaching nail is a driver g
firmly secured in the block g³ and of about the same diameter as the nail heads.
These drivers pass through the top plate and finish level with its upper surface
when the same is maintained in its highest position by the springs but when pressure
is applied to the plate so as to cause the springs to yield the drivers stand through
a little above the plate surface.
The attaching of the heel to the boot is done by the operation of the machine
lifting the rods h h so as to raise the device into the position shewn at B in Figs. 1
and 2. The device in rising carries up the mould and the heel g' until the latter
comes in contact with the sole of the boot which in this case is not (as described in
Specification No. 15540, A.D. 1891) automatically moved down upon the heel but
is set at the proper height above it to suit the length of the nails at the time in use.
The upward movement of the heel is arrested by the boot sole and the spring
pistons 9 yield as the device rises until the plate a' comes in contact with the
heel g and if the heel be of extra height the plate g' and springs 98 also field but
the drivers g being unyielding rise always to the same height irrespective of any
slight variation in the height of the heel as an extra high heel will as before stated
depress the top plate 97 and the drivers will enter the heel to the amount of
its extra height slightly burying the nail heads therein and uniformly clinching the
nail points against the iron last or seat plate.

page_text: The device shewn in Figs. 5 and 6 is for attaching to a boot a heel not previously
charged with nails. It may be carried as before on the table g (see also before
mentioned Specification Fig. 11.) and the nails are placed in the holes i. The nail
block is formed with a supporting shell in which the driver block rises and
falls when operated by the movement of the driving rods h h. The rising of the
block lifts the drivers to a uniform height and drives the attaching nails out of
the holes i so as to attach the heel. The top plate is supported on springs and
yields as before described to a heel of extra height so that the drivers i enter
a little distance into the heel and slightly bury the heads of the nails.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is.
