PROVISIONAL SPECIFICATION.
Improvements in Machines and Dies for Making Heels and Attaching
them to Boots and Shoes.
WILLIAM DOUGLAS and EDWIN DOUGLAS, of Hanham Road, Kingswood, in
the County of Gloucester, Engineers and Ironfounders, do hereby declare the
nature of this invention to be as follows:-
It has for its object the making and attaching of heels to boots and shoes.
The machine has a suitable frame, with bosses and bearings for carrying a
driving shaft, crank shafts, plungers, and a table with slides for carrying dies. On
the driving shaft are fast and loose pulleys, a flywheel, and a pinion; in gear with
this pinion are two tooth wheels, attached to which are clutches; each of these
tooth wheels with the clutch attached, runs loose on a separate crank shaft by the
side of a bossed flange, which is keyed to the crank shaft. In a suitable position
in each of these bossed flanges is a hole to carry a catch, which is put in and out of
gear with its respective clutch by means of levers and springs, which are controlled
by two separate and independant treadles. Pivoted to the frame in a suitable
position to engage with the catch in bossed flange on top crank shaft, is a double
armed lever, by means of which the catch is thrown in or out of gear, causing the
upper plunger to stop on completion of down and upstrokes at the will of the
operator.
A similar lever with one arm only, engages with the catch in bossed flange on
bottom crank shaft, the lower plunger not being required to stop until the bottom
crank has made a complete revolution, during which the lower plunger rises to drive
nails, and returns.
.
These levers are connected by rods to the treadles before mentioned.
The cranked part of the top crank shaft is at the opposite end to the tooth wheel;
on the crank works a sliding bearing, which slides in the top end of the upper
plunger, which has a suitable slot for the bearing to work in.
The lower end of the plunger has an adjustment for regulating the platen to the
varying heights of heels required to be made or attached.
Working on bottom crank is a connecting rod, the lower end of which is
connected to an arm on a rocking shaft, which works in a suitable bearing below
the table referred to. On the opposite end of the rocking shaft is another arm, to
which, by means of links, is connected the lower plunger.
The working of the machine is as follows:-The machine being at rest, with the
top plunger at top of stroke, the leather to form the heel is placed in a mould, and
the die underneath being fed with nails in the ordinary way, the treadle controlling
the motion of the upper plunger, is depressed, causing the plunger to descend, and
stop on the leather compressing it, while the other treadle is depressed, causing the
under plunger to rise, drive the nails, return and stop. On releasing the first
treadle the upper plunger rises and stops, ready for the next operation.
In attaching heels to boots, the boot is placed on a suitable attaching pillar, the
motion of the machine being the same as before described, the upper plunger
coming down to hold the heel in position, while the under plunger rises to drive the
nails, attaching the heel firmly to the boot.

page_text: The motions of the upper and lower plungers are actuated independantly, so
that the operator may fix the heel, and see that it is in its right position before
driving the nails.
The ordinary heel making and attaching dies can be used, but for making heels
with metal plates or tips, we employ a die, preferably round, with a suitable square
or oblong base to fit in slide on table.
The top part of the die is recessed to the contour of the metal plate or tip,
and is provided with the usual pins or drivers for driving the nails which fasten
the piece of leather called the tip filler, to the heel, filling up the space inside
the tip.
In suitable positions round the die, two or more dogs or grips slide in grooves,
preferably by means of springs, towards the recess which is to receive the tip, a
suitable cam ring with cams or wedge pieces attached, embracing the die for the
purpose of moving the dogs or grips outward from the recess while the tip is being
inserted.
On the upper side of dogs or grips are inclined projections, corresponding
with similar inclines on the under side of the mould which receives the leather
to form the heel.. Pressure being applied the mould descends, and the tip nails
having entered the leather, the grips are forced outward releasing the tip.
Vertical springs are employed to keep the mould sufficiently high above the tip
to clear the nails by which the tip is to be attached.
In making the heel the operator first draws back the dogs or grips by means of
the cam ring the tip having been previously fed with nails, is inserted in the die,
the points of the nails being upward. The grips being released by means of the
cam ring, are impelled towards the tip by the springs, and hold it securely in
position.
The die being fed with nails and the tip filler put in the tip, the mould is
placed in position over the die, and filled with leather to the required height of
heel.
The die with the mould is then placed under the platen of the machine, which
is actuated as before described.

Improvements in Machines and Dies for Making Heels and Attaching
them to Boots and Shoes.
WILLIAM DOUGLAS and EDWIN DOUGLAS, of Hauham Road, Kingswood
in the County of Gloucester, Engineers and Ironfounders, 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 :-
Wn
It has for its object the making and attaching of heels to boots and shoes.
The machine has a suitable frame, with bosses and bearings for carrying a
driving shaft, crank shafts, plungers and a table with slides for carrying dies.
the driving shaft are fast and loose pulleys, a flywheel and a pinion; in gear with
this pinion are two tooth wheels, attached to which are clutches; each of these
tooth wheels with the clutch attached, runs loose on a separate crank shaft by the
side of a bossed flange, which is keyed to the crank shaft. In a suitable position
in each of these bossed flanges is a hole to carry a catch, which is put in and out of
gear with its respective clutch, by means of levers and springs, which are controlled
by two separate and independant treadles. Pivoted to the frame in a suitable
position to engage with the catch in bossed flange on top crank shaft, is a double
armed lever, by means of which the catch is thrown in or out of gear, causing

page_text: the upper plunger to stop on completion of down and upstrokes at the wit of the
operator.
A similar lever with one arm only, engages with the catch in bossed flange on
bottom crank shaft, the lower plunger not being required to stop until the bottom
crank has made a complete revolution, during which the lower plunger rises to drive
nails, and returns.
These levers are connected by rods to the treadles before mentioned.
The cranked part of the top crank shaft is at the opposite end to the tooth
wheel; on the crank works a sliding bearing, which slides in the top end of the
upper plunger, which has a suitable slot for the bearing to work in.
The lower end of this plunger has an adjustment for regulating the platen to the
varying heights of heels to be made or attached.
Working on bottom crank is a connecting rod, the lower end of which is
connected to an arm on a rocking shaft, which works in a suitable bearing below
the table referred to. On the opposite end of the rocking shaft is another arm, to
which, by means of links, is connected the lower plunger.
The working of the machine is as follows:-The machine being at rest with the
top plunger at top of stroke, the leather to form the heel is placed in a mould, and
the die underneath being fed with nails in the ordinary way, the treadle controlling
the motion of the upper plunger is depressed, causing the plunger to descend, and
stop on the leather, compressing it, while the other treadle is depressed, causing the
under plunger to rise, drive the nails, return and stop. On releasing the first
treadle the upper plunger rises and stops ready for the next operation.
In attaching heels to boots, the boot placed on a suitable attaching pillar, the
motion of the machine being the same as before described, the upper plunger
coming down to hold the heel in position, while the under plunger rises to drive the
nails, attaching the heel firmly to the boot.
The motions of the upper and lower plungers are actuated independantly, so
that the operator may fix the heel, and see that it is in its right position before
driving the nails.
The ordinary heel making and attaching dies can be used, but for making heels
with metal plates or tips we employ a die, preferably round, with a suitable square
or oblong base to fit in slide on table.
The top part of the die is recessed to the contour of the metal plate or tip,
and is provided with the usual pins or drivers for driving the nails which fasten
the piece of leather called the tip filler, to the heel filling up the space inside
the tip.
In suitable positions round the die two or more dogs or grips slide in grooves,
preferably by means of springs towards the recess which is to receive the tip, a
suitable cam ring with cams or wedge pieces attached embracing the die for the
purpose of moving the dogs or grips outward from the recess while the tip is being
inserted.
On the upper side of the dogs or grips are inclined projections corresponding with
similar inclines on the under side of the mould which receives the leather to form
the heel. Pressure being applied the mould descends, and the tip nails having
entered the leather, the grips are forced outward releasing the tip.
springs are employed to keep the mould sufficiently high above the tip to clear the
nails by which the tip is to be attached.
Vertical
In making the heel the operator first draws back the dogs or grips by means of
the cam ring; the tip having been previously fed with nails, is inserted in the die,
the points of the nails being upward. The grips being released by means of the
cam ring, are impelled towards the tip by the springs, and hold it securely in
position.
The die being fed with nails and the tip-filler put in the tip, the mould is
placed in position over the die, and filled with leather to the required height of
heel. The die with the mould is then placed under the platen of the machine
which is actuated as before described.

page_text: In order that the invention may be fully understood the following further
description is given in reference to the accompanying drawings wherein
Fig. 1 is a side and Fig. 2 a front elevation of a machine for making heels and
attaching them to boots and shoes.
Fig. 3 is a section of bossed flange, and tooth wheel with clutch.
Figs. 4. 5. and 6 are details of clutch arrangement.
Figs. 7 and 8 are sections, and 9. 10. 11 and 12 are details of a die mould and
slide, for making heels with metal plates or tips.
In Figs. 1 and 2 A is the frame with bosses A¹ A' A³ A* A* A° for_carrying a
driving shaft B, crank shafts C and D, plungers E and F and a table P. On the
driving shaft B are fast and loose pulleys, a flywheel and a pinion G. In gear with
this pinion are two tooth wheels H and J attached to which are clutches H and J';
each of these tooth wheels H and J with its respective clutch runs loose on the
respective crank shafts C and D by the side of bossed flanges H2 J2 which are
keyed to the respective crank shafts C and D. In a suitable position in each of
these bossed flanges H2 J2 is a hole to carry a catch H3 J3 which is put in and out
of gear with its respective clutch H¹ J1 by means of levers K K' and
springs LL LL³ which are controlled by treadles M M' connected to levers K K'
by rods N N¹.
Pivoted to the frame in a suitable position to engage with the catch H³ in bossed
flange H2 on crank shaft C is a double armed lever K by means of which the
catch H³ is thrown in or out of gear, causing the plunger E to stop on completion
of down and upstrokes at the will of the operator.
A similar lever K' but with one arm only, engages with the catch J³ in bossed
flange J² on crank shaft D, the plunger F not being required to stop until the
crank shaft D has made a complete revolution, during which the plunger F rises to
drive nails and returns.
These levers K K¹ are connected by rods N N' to treadles M M¹.
The cranked part of the crank shaft C is at the opposite end to the tooth wheel H;
on the crank shaft C works a sliding bearing C which slides in the top end of
plunger E which has a suitable slot for the bearing to work in.
The lower end of plunger E is adjustable vertically by means of a screw and
hand wheel E'.
Working on crank shaft D is a connecting rod Q the lower end of which is
connected to an arm on a rocking shaft R which works in a suitable bearing R¹
below the table P. On the opposite end of the rocking shaft is another arm to
which by means of links R2 is connected the plunger F.
The working of the machine is a follows:-The machine being at rest with the
plunger E at top of stroke, the leather to form the heel is placed in a mould S,
and the die T underneath, being fed with nails in the ordinary way, the treadle M¹
controlling the motion of plunger E is depressed, causing it to descend and stop on
the leather, compressing it, while the treadle M is depressed, causing the plunger F
to rise, drive the nails, return and stop. On releasing the treadle M¹ the plunger E
rises and stops ready for the next operation.
In attaching heels to boots, the boot is placed on a suitable attaching pillar, the
motion of the machine being the same as before described, the plunger E coming
down to hold the heel in position, while the plunger F rises to drive the nails,
attaching the heel firmly to the boot. The motions of the plungers E and F are
actuated independantly, so that the operator may fix the heel, and see that it is in
its right position before driving the nails.
The ordinary heel making and attaching dies can be used, but for making heels
with metal plates or tips we employ a die shown in detail in Figs. 7. 8. 9. 10. 11. 12.
Sheet 2 of accompanying drawings.
The top part of the die T is recessed to the contour of the metal plate or tip, and
is provided with the usual pins or drivers U for driving the nails which fasten the
piece of leather called the tip-filler to the heel filling up the space inside the tip.
In suitable positions round the die T two or more dogs or grips T¹ T* slide in

page_text: grooves preferably by means of springs W W' towards the recess which is to
receive the tip, a suitable cam ring V with cams or wedge pieces V₁ V' attached,
embracing the die T for the purpose of moving the dogs T T outward from the
recess while the tip is being inserted.
On the upper side of dogs T¹ T2 are inclined projections corresponding with
similar inclines on the under side of the mould S which receives the leather to form
the heel. Pressure being applied the mould S descends, and the tip nails having
entered the leather, the dogs T' T' are forced outward releasing the tip.
Vertical springs S'S' are employed to keep the mould S sufficiently high above
the tip to clear the nails by which the tip is to be attached.
In making the heel, the operator first draws back the dogs T¹ T' by means of
the cam ring V. The tip having been previously fed with nails is inserted in the
recessed part of the die T, the points of the nails being upwards.
The dogs T T being released by moving the cam ring V in the direction of the
arrow, are impelled towards the tip by the springs W W' and hold it securely in
position.
The die T being fed with nails, and the tip filler placed in the tip, the mould S
is placed in position over the die as shown in Fgs. 1. 2. 7. 8. and filled with leather
to the required height of heel.
The die slide X containing the die T with the mould S is then placed under the
plunger E of the machine which is actuated as before described.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :--
1. In a heeling machine the combination of crank, clutch, sliding bearing,
plunger, lever, springs and treadle, which admits of top plunger coming to rest at
top or bottom of stroke at the will of the operator, substantially as and for the
purpose described and illustrated in the accompanying drawings.
2. In a heeling machine the combination of crank, clutch, connecting rod, rocking
shaft, plunger, lever, springs and treadle, which admits of bottom plunger rising to
drive nails, and automatically stopping on completion of the down stroke,
independant of the motion of the top plunger, substantially as and for the purpose
described and illustrated in the accompanying drawings.
3. In a heel making die the combination of mould, die, cam ring, cams or
wedges, dogs, and springs, which admits of a metal tip being held firmly in position,
while the leather to form the heel, is forced on to the nails which are to attach the
tip to the heel, substantially as and for the purpose described and illustrated in the
accompanying drawings.
