Improvements in Heel Building Machines.
.G
I, WILLIAM HENRY DORMAN, of The Green Hall, Stafford, Engineer, do
hereby declare the nature. of this. invention to be as follows-
The machine consists of a circular table made in the form of a ring which
is automatically and intermittently revolved and which carries a number of
similar moulds for the reception of the heel lifts. Also in a series of stationary
boxes or receptacles, occupying the centre of the ring table, for containing the
lifts for building the heels. Also in a nailing together apparatus which
automatically nails together each heel as it is passed around by the revolving
table. Also in a knocking out arrangement which discharges each heel from
its mould as soon as the nailing together operation is completed.
The circular ring table is divided around into ten, twelve, or other suitable
number of divisions, according to the maximum number of lifts required for
building the heel and each division carries a mould for receiving the successive
lifts of the heel.
The stationary boxes-which are two in number less than the divisions of
the circular table-each contain one particular size of lift intended to occupy
one particular place in the heel as the first, second, third, etc. Opposite to
each box a boy or girl is seated, the first of whom takes one lift from his
particular box and places it in one of the moulds as soon as the latter. comes
to rest before him. The mould then passes on to the next boy, and the next,
and so on, each of whom places a lift upon the last until the heel is built up
to its full number of lifts. From the last boy the heel passes to the nailing
together apparatus and from thence to the knocking out arrangement. There
are of course as many young people employed in building the heel as the heel
has lifts and as each person simultaneously places a lift in a mould. a heel
is completed with every stoppage of the table. An extra boy is required to
reload the nailing together devices with nails as they are successively emptied
by the operation of the machine.
The construction of the machine is as follows:-
A pulley, shaft, and pair of gears impart movement to a cam shaft which
by means of a suitable cam and connections to a ratchet wheel imparts an
intermittent revolving movement: to the ring table and to a nail loading table
suitably geared to the same. Another cam operates a pair of toggles, or the
like, with suitable connections to a ram, so as to put downward pressure on
the heel, while the same, or another cam, and toggles operate a nail driving
device so as to drive nails through the lifts and hold the heel together.
Another cam and lever operates the knocker out which preferably consists
of three rods which rise through holes in the bottom of the heel mould and
lift up the heel while a clearing lever, operated by a cam, sweeps the heel into
a basket suitably placed to receive it.

page_text: The device loading table revolves and stops in unison with the ring table
and has a series of nail loading places around its edge which are successively
filled by the attending youth. These places pass in succession under the heels
and the nails are driven up into the heel. by the before mentioned driving
device.
An automatic locking lever is provided which alternately locks and releases
the ring table, being operated by a. suitable cam and connections.

I, WILLIAM HENRY DORMAN, of The Green Hall, 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:-
The machine consists of a circular table made in the form of a ring which
is automatically and intermittently revolved and which carries a number of
similar moulds for the reception of the heel lifts. Also in a series of stationary
boxes or receptacles, occupying the centre of the ring table, for containing the
lifts for bunding the heels. Also in a nailing together apparatus which
automatically nans together each heel as it is passed around by the revolving
table. Also in a knocking out arrangement which discharges each heel from
its mould as soon as the mailing together operation is completed.
The circular ring table is divided around into ten, twelve, or other suitable
number of divisions, according to the maximum number of lifts required for
building the heel and each division carries a mould for receiving the successive
lifts of the heel.
The stationary boxes which are two in number less than the divisions of
the circular table each contain one particular size of lift intended to occupy
one particular place in the heel as the first, second, third, etc. Opposite to
each box a boy or girl is seated, the first of whom takes one lift from his.
particular box and places it in one of the moulds as soon as the latter comes
to rest before him. The mould then passes on to the next boy, and the next,
and so on, each of whom places a lift upon the last until the heel is built up
to its full number of lifts: From the last boy the heel passes to the nailing
together apparatus and from thence to the knocking out arrangement. There
are of course as many young people employed in building the heel as the heel
has lifts and as each person simultaneously places a lift in a mould a heel
is completed with every stoppage of the table. An extra boy is required to
reload the nailing together devices with nails as they are successively emptied
by the operation of the machine.
The construction of the machine is as follows:-
A pulley, shaft, and pair of gears impart movement to a cam shaft which
by means of a suitable cam and connections to a ratchet wheel imparts an
intermittent revolving movement to the ring table and to a nail loading table
suitably geared to the same. Another cam operates a pair of toggles, or the
like, with suitable connections to a ram, so as to put downward pressure on
the heel, while the same, or another cam, and toggles operate a nail driving
device so as to drive nails through the lifts and hold the heel together.
Another cam and lever operates the knocker out which preferably consists

page_text: of three rods which rise through holes in the bottom of the heel mould and
lift up the heel while a clearing lever, operated by a cam, sweeps the heel into
a basket suitably placed to receive it.
The device loading table revolves and stops in unison with the ring table
and has a series of nail loading places around its edge which are successively
illed by the attending youth. These places pass in succession under the heels
and the nails are driven up into the heel by the before mentioned driving
levice.
An automatic locking lever is provided which alternately locks and releases
he ring table, being operated by a suitable cam and connections.
The machine is illustrated by the accompanying drawings in which:-

Fig. 4 is a vertical section through a mould and the nail loading table.
The pulleys a a¹, shaft a², pinion a³, and wheel a, give motion to the cam
shaft, all being suitably carried in the frame aº.
The main cam 4 engages a roll band operates a pair of toggles 62 and c
which are connected with an upper beam 6 and a lower beam c mounted on
centre pins 6+, in the frame a
The upper beam, through the adjusting screw 65, ram 66, and stamping
head 67, puts downward pressure on the heel lifts & enclosed in the heel

The lower beam o acts upon a ram to force up drivers and drive nails.
into the heel lifts d for holding the heel together.
By means of the hand wheel the operator can adjust the height of the
stamping head 67 to suit heels of different heights.
A spring may be provided to prevent the beam c¹ from operating until
after the head has brought pressure to bear upon the heel lifts.
The moulds e to e-in the machine illustrated ten moulds are employed-
are arranged at equal distances all around the circular ring table f which is
free to revolve in a horizontal direction as shewn by the arrow and is driven
intermittently, a tenth of a revolution at a time, by suitable gear

revolved while the head 67 and drivers are out of action and rests while they
operate.
The pawl falso revolves the nailing device table which is carried on
the same vertical shaft cas is the ratchet wheel f6.
This table has six devices perforated in it to 13 and is revolved one sixth
of a revolution to each one tenth revolution of the ring table f so that a
device and a mould always come together between the head 67 and the drivers c*..
Of course these proportions of one sixth and one tenth may be varied.
:
An operator drops two or three nails head downward into each of the nailing:
together devices in the table c as they come round which nails are prevented
from dropping through to the floor by the stationary plate c¹4
This plate is perforated at one place for the drivers e to pass through it,
such perforations coinciding, after each movement of the table c", with one of
the sets of perforations in the table. The drivers never leave the perforations
formed in the plate which therefore acts as a permanent guide to them
but they rise and fall through the table e with each movement of the beam c¹,
driving up the nails out of the table and into the heel on their upward stroke
and falling until their upper ends are clear of the under side of the table so
that the latter may revolve.
After each heel is built and nailed together it has to be delivered from its
mould which is done by a rising ram g and a clearing arm h.

page_text: -
The ram is forced upwards so as to lift the heel d' out of the mould by
a lever g mounted on a pivot 2 and operated by a cam g', roll g, and arm g³.
The clearer swings upon a pivot (a continuation of 6) and sweeps the
heel off into a conveniently placed receptacle as i. It is operated by a link h²,
cam lever, cam ht, and roll h
The moulds e, e' around the table f are all precisely alike and the boxes to
(only shewn in plan) contain each one size of lift, thus, the smallest lifts are
in the box, the next size above in the box j', and so on to the largest lifts
in the box, the machine as drawn being intended to build heels up to eight
lifts in height.

The lever (shewn only in Fig. 3) locks and releases the table 6, its tooth 1
entering and leaving the notches provided in the table edge. It is mounted
on the pivot and operated by the cami kt.
