"IMPROVEMENTS IN APPARATUS FOR HEELING BOOTS AND SHOES AND IN
STAMPING PRESSES SUITABLE FOR WORKING SUCH APPARATUS [The result partly
of a communication to him from abroad by Virgil Randolph Wilson Keats, of
Mons, in the Kingdom of Belgium, and partly of invention and discovery made
by him.]
The chief object of this invention is so to construct the apparatus employed for
applying the attaching nails to the heels of boots and shoes that a large variety of
forms and sizes of heels may be built up and secured by the use of one set
of dies.

To this end I fit the pins which severally act as drivers of the nails to a pair of
hinged arms, to the hinge pin of which is pivotted a slotted arm. The arms which
carry the drivers are extended rearwards to carry each a fulcrum pin for receiving
a link which links are coupled together by a clamping screw that passes through
the slotted arm lying between the rear ends of the arms carrying the drivers. By
shifting this screw along its slot and clamping it, the hinged arms are made to
approach to or recede from each other, and are held firmly in their adjusted
position; a scale on the slotted arm and a pointer carried by the clamping screw
facilitating the adjustment of these arms to suit the work in hand. Immediately
below the arms the driving pins are placed: they are made preferably with heads
to fit countersunk holes in plates which are attached to the underside of the arms by
screws, and thus firmly hold the drivers in position. These drivers are so arranged
that they will correspond to holes made in blocks for carrying the nails by which
the "lifts" composing the heel are attached to the boot or shoe. The pierced blocks
are secured to the arms by guide rods and they are of a thickness to correspond

page_text: to the length of the nails employed. To prevent the nails which are fed to the
blocks by hand from dropping through, a "lift," or one of the layers of leather to
form the heel, is held against the underside of the blocks by clip springs, the "lift"
being applied to the blocks before the insertion of the nails therein.
It will now be understood that when the hinged arms are adjusted to bring the
drivers which they carry over the heel to be attached, the blocks carrying the nails
will move inwards or outwards with the arms, and thus the drivers will stand
immediately over the holes in the blocks which carry the nails. This apparatus I
mount in a press of peculiar construction which permits of the screw that puts the
nailing apparatus into action being driven by friction in opposite directions at the
will of the workman.
The screw which is mounted in a Bracket,,standard is threaded on portion only
of its length the upper, part being grooved longitudinally to receive a fixed feather
which will prevent it from rotating. The threaded part of the screw works in au
elongated nut which forms the hub of a heavy friction pulley and is mounted.
loosely in a bearing of the bracket standard.
This nut or hub is flanged at its lower end for the purpose of limiting its endway.
motion upwards. The lower end of the screw is formed with a socket or rebated
slot to receive a tang projecting from the slotted arm above mentioned for the
purpose of connecting the nailing apparatus with the press screw. For the purpose
of driving the friction pulley, two friction drums are provided the same being
mounted on short shafts carried each by a pair of arms mounted on vertical shafts
supported in bearings bolted to the standard of the press. These arms are linked
together so that the throwing of one drum into action or in contact with the
friction pulley will throw the other drum out of action. To the drum shafts are
keyed pinions which gear respectively into spur wheels mounted on the vertical
shafts carried by the bracket bearings. These spur wheels gear into each other and
one is keyed to its shaft while the other is loose on its shaft.
1
The shaft having the keyed spur wheel is rotated through, bevil gear from a
driving shaft; and the other shaft is capable of receiving.a slight axial motion from
a pedal or its equivalent for the purpose of shifting the friction drums in and out
of action, the arms of which it is the fulcrum being keyed thereto for the purpose
of transmitting the requisite lateral motion to the friction drums.
Supposing now that a heel is to be built up. upon a boot by this apparatus, the
nails are inserted in the pierced blocks or dies as explained, and the boot with
suitable "lifts" or layers of heel leather applied. thereto; is presented to the
apparatus by a metal last adjusted to the required position. Rotary motion. is then
imparted to the heavy friction pulley by the means just described, to drive down
the screw together with the apparatus which it carries. By rotating this pulley it
will receive a tendency to rise or run up the screw, but its weight will cause it to
drive down the screw until the blocks or dies carrying the nails press upon the
heel, and the drivers following up this movement drive the nails into the leather.
The friction pulley will then run up the screw until arrested by the flange on the
lower end of its hub. The action will then be that of a stationary rotating nut
forcing down the screw by its rotation with its full energy. The result of this
supplementary action will be to drive home the nails at which time the rotary
action of the pulley will cease. The attendant will then, by means of the pedal,
shift the friction drums and thereby reverse the direction of rotation of the friction
pulley for the purpose of lifting the press screw and releasing the boot. If the heel
has not been completed by this one operation additional "lifts" may be applied to
build it up to its full height, and the boot may then be re-submitted to the action
of the apparatus. This press it will be understood may be applied to a variety of
kindred purposes it being applicable wherever the pressure of dies is required to
be imparted to yielding non-metallic materials.

"IMPROVEMENTS IN APPARATUS FOR HEELING BOOTS AND SHOES AND IN
STAMPING PRESSES SUITABLE FOR WORKING SUCH APPARATUS
"the result partly
of a Communication to me from abroad by Virgil Randolph Wilson Keats of Mons
in the Kingdom of Belgium
The chief object of this Invention is so to construct the apparatus employed for
applying the attaching nails to the heels of boots and shoes that a large variety of
forms and sizes of heels may be built up and secured by the use of one set
of dies
In Sheet I of the accompanying drawings I have shewn in several views the
apparatus for holding in position and for driving the nails used for securing to the
boot or shoe the thicknesses of leather which go to form the heel.
Fig: 1 is a plan view of the heeling apparatus detached from the press employed
to operate it. Fig: 2 is a side view of the apparatus and Figures 3 and 4 are views
of the opposite ends of the apparatus.
A A is a pair of hinged arms to the underside of which are fitted the pins which
severally act as drivers of the nails that are to be inserted in the leather
These arms are connected to a slotted block B. by means of their hinge pin a on
the upper face of which block is formed a dovetailed projection that serves to
connect the heeling apparatus with the press.
The arms A A are extended rearwards to carry each a fulcrum pin for receiving
the links a¹ which are coupled together by a clamping screw a².-This clamping
screw a² passes upwards through the block B which is situate between the rear
ends of the arms A.
The block B (see the detached side elevation fig: 1) is slotted horizontally to
receive the links a' and to permit of their moving freely in the block and it is
also slotted vertically to allow of the clamping screw a being shifted lengthwise
of the block.
By shifting this screw along its slot and clamping it the hinged arms A A are
caused to approach to or recede from each other and are held firmly in their
adjusted position a scale on the block B and a pointer carried by the clamping screw
facilitating the adjustment of these arms to suit the work in hand
a³ are the driving pins made preferably with heads to fit countersunk holes in
underlying clamping plates A' one of which is shewn detached in plan view at
Fig: 2 These plates are attached to the underside of the arms A by screws and
thus firmly hold the drivers in position. These drivers are so arranged that they
will correspond to holes made in blocks C for carrying the nails by which the
lifts
or thicknesses of leather composing the heel are attached to the boot or shoe.
The pierced blocks C C are connected to the hinged arms A A by guide rods c c
which stand up from the blocks and pass through holes in the plates. A' and arms A.
This connection of the blocks with the hinged arms ensures their adjustment with
the arms through the links a¹ and clamping screw a².
"
The blocks C are made of a thickness to correspond to the length of the nails
employed. To prevent the nails which are fed to the blocks by hand from dropping
through a "lift" or one of the layers of leather to form the heel may be held
against the underside of the blocks by clip springs c¹the "lift" being applied to
the blocks before the insertion of the nails therein.

page_text: It will now be understood that when the hinged arms A are adjusted to bring
the drivers which they carry over the heel to be attached the pierced blocks c c
carrying the nails will move inwards or outwards with the arms and thus the
drivers will stand immediately over the holes in the blocks which carry the nails.
This apparatus I mount in a press of peculiar construction which permits of the
screw that puts the nailing apparatus into action being driven by friction in
opposite directions at the will of the workman.
In Sheets II. III and IV of the drawings I have shewn in several views the
improved construction of press which I employ for operating the heeling apparatus
Fig: 5 is a side view of the press Fig. 6 is a plan view and Fig: 7 is a front
view of the same. In these Figures D is a bracket standard cast in one with the
bed plate which is supported on cast iron legs D¹ bolted thereto.
This standard carries in front a vertically sliding rod E which is threaded on a
portion of its length to receive a hollow screw F which forms the hub of a
weighted friction wheel F¹.

I
The standard is provided with two arms d d¹ in which the rod E is mounted.
The upper end of this rod is.grooved to receive a fixed feather fitted to the
arm d and in the .arm d! a. bearing is formed for the reception of the hollow:
screw F which is free to turn in its bearing.
.
The hollow screw or hub Fis flanged at its lower end below the bearing for the
purpose of limiting its endway motion upwards. The lower end of the screwed
rod E is formed with a dovetailed slot to receive the dovetailed projection of the
block B above mentioned and thereby to connect the heeling apparatus with the
press as seen at Fig. 4.

For the purpose of driving the friction pulley. F1 two friction drums G G are
provided the same being mounted on short shafts g g carried each by a pair of
arms G G✶ mounted respectively, on vertical shafts G2 G3 supported in bearings
bolted to the standard of the press.
The arm G* mounted on the shaft G³ is keyed thereto. for the purpose to be
presently explained but the arm G' carried by the shaft G2 is loose thereon.
These arms are connected together; by a link G so that the throwing of one
drum into action or in contact with the friction pulley' will throw the other drum,
out of action.
To the drum shafts g are keyed pinions which gear respectively into spur.
wheels g g mounted on the vertical shafts G² G³.
.
These spur wheels gear into each other the wheel g¹ being keyed to its shaft G2.
while the other gis loose on its shaft G³.
The shaft G2 is rotated through bevil gear from a horizontal driving shaft H.
mounted in bearings on the standard. The shaft G³ is capable of receiving a
slight axial motion from a pedal. I for the purpose of shifting the.friction drums in..
and out of action the arm G* of which this shaft is the fulcrum being keyed.
thereto for the purpose of transmitting the requisite lateral motion to the friction
drums.
Supposing now that a heel is to be built up upon a boot by the heeling
apparatus attached to the press the nails are inserted in the pierced block Cas
explained and the boot with suitable "lifts" or layers of heel leather applied
thereto is presented to the apparatus upon a metal last which is clamped to a
slide adjusted on the bed plate to the required position.
! Rotary motion is then imparted to the heavy friction pulley by the means just
described to enable its screwed hub F to force down the screwed rod E together
with the apparatus which it carries.
By rotating this pulley it will receive a tendency to rise or run up the screwed
rod but its weight will cause it to drive down the rod until the blocks or dies
carrying the nails press upon the heel and the drivers following up this movement,
drive the nails into the leather.
The friction pulley will then run up the rod until arrested by the flange on the
•
E

page_text: lower end of its hub The action will then be that of a stationary rotating
nut forcing down by its continued rotation the screwed rod with its full energy.
The result of this supplementary action will be to drive home the nails after
which the rotary action of the pulley will cease.
The attendant will then by means of the pedal I shift the friction drums and
thereby reverse the direction of rotation of the friction pulley F' for the purpose
of lifting the screwed rod E with its attached heeling apparatus and releasing
the boot.
If the heel has not been completed by this one operation one or more additional
lifts or thicknesses of leather may be applied, to build it up to its full height and
the boot may then be re-submitted to the action of the apparatus. This press it
will be understood may be applied to a variety of kindred purposes it being
applicable wherever the pressure of dies is required to be imparted say to yielding
non-metallic minerals.
Having now explained the nature of the said Invention for Improvements in
apparatus for heeling Boots and Shoes and in stamping presses suitable for working
such apparatus, I wish it to be understood that under the above in part recited
Letters Patent I claim :
First Constructing heeling apparatus with a pair of adjustable hinged arms
fitted on their underside with pins or drivers and connected by means of guide
rods with pierced blocks for receiving the nails to be driven, such apparatus being
capable of facile attachment to a stamping press substantially in the manner and
for the purpose above set forth.
Second The construction of stamping press above described consisting in a
vertically moving screwed rod carrying the device intended to be set in action by
the press and operated by a friction pulley with threaded hub working on the
screwed rod, such friction pulley being driven in opposite directions at the will of
the operator by friction drums thrown into and out of action by a rock shaft as
set forth.
In witness whereof I the said John Keats have hereunto set my hand and
seal the fourth day of June in the year of our Lord One thousand eight
hundred and eighty three.
