PROVISIONAL SPECIFICATION.
Improved Heel Building and Attaching Machine for Boots and
Shoes.
JAMES BRIDGE Shoe Manufacturer Kettering Road Northampton do hereby declare
the nature of this invention to be as follows:
This Invention relates to a Machine in which heels for Boots and Shoes are built
up and attached to the boots-the top piece put on and the heel breasted without
removing the boot from its last or jack. It has been usual to build up the heels in a
separate Machine. My Invention consists of a special shape of mould in which the
lifts for making the heels are built, having an open front to receive the waist of the
boot. The boot is put on to a jack under which the mould is placed-the die in
the mould is fitted with plungers which drive the sprigs or nails through the lifts and
attach them in one operation to the boot. The points of the sprigs being clenched
on the inside of the boot. The plungers are actuated by a can, lover, or other
device. This mould and die are easily moved from under the jack and a similar
mould in which the top piece is placed comes under the jack-and the top piece put
on without removing the boot. I can also disponse with the jack-and by the use of
à socket can attach the heels whilst the boot is on its last. Connected with the
plunger which drives on the top piece I insert a knife for breasting the heel which
does its work at the same time that the top piece is being attached.

Improved Heel Building and Attaching Machine for Boots and
Shoes.
I JAMES BRIDGE of Kettering Road Northampton in the County of Northampton
Shoe manufacturer do hereby declare the nature of any said invention and in what
manner the same is to bo performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to a machine in which heels for boots and shoes are built
up and attached thereto the top piece being put on and the heel breasted without
removing the boot from its last or jack.
It has hitherto been usual to build up the heels in a separate machine.
My invention consists in a special shape of mould in which the lifts for making the
heel are built having an open front to receive the waist of the boot.
The boot is put on a jack under which the mould is placed; the die in the mould
is fitted with plungers which drive the sprigs or nails through the lifts and attach
them in one operation to the boot the points of the sprigs being clenched on the
inside. The plungers are actuated by a cam, lever, or other device.
This mould or die is easily moved from under the jack and a similar mould on
which the top piece is placed comes under the jack and the top piece is put on without
removing the boot.
A knife for breasting the heel is also actuated by the plunger at the same time that
the top piece is being attached.
Referring to the accompanying drawings and to the figures and letters of reference
marked thereon..

Figure 2 is a side elevation of the same with some of the parts shown in
section.
Figure 3 is an enlarged section of one of the sliding standards shewing the open
mouthed mould and the breasting knife.
Figure is a plan of the said mould showing die for sprigging and edge of
breasting knife.
"
In carrying out my invention I arrange a casting or frame A supporting the
working parts of the machine. B B are fast and loose pulleys mounted on a
spindle C working in bearings D. E is a bracket carrying a scrowed sleeve E in
which works the adjusting screw G on to which is socketted or otherwise fitted the
bracket or block T sliding up or down in grooves in the frame E and carrying the
jack F which may be advanced or receded in the slide block T by means of
the screw and wheel I (in a similar manner to that in a slide rest in a lathe) for
the purpose of altering the position of the heel of the boot or shoe.
on
a similar
Jis an open mouthed or open fronted mould placed in position on a moveable or
sliding standard K for the purpose of attaching the heel or
standard K (also containing the breasting knife) for the purpose of sprigging and
breasting.
The open mouthed mould J is shewn enlarged in Figure 3 and it will be seen that
the boot can be placed therein with the heel portion fitting into a recess immediately
over the plunger hereinafter described and so that the waist of the boot projects
through the open front J' of the mould J.
Within the standard K is placed a die containing the pins for the purpose of
attaching the lifts to the boot the said pins being placed in recesses therein with
the points upwards and within the standard K¹ is placed a die of similar character.
containing the sprigs which have been previously inserted in the holes or recesses also
point upwards.
The standards K and K¹ are arranged to slide on a bed plate and are withdrawn
to the right and left by hand when not required to be under the adjusting screw and
jack where they are centred when in use for building the heel or sprigging and
breasting.
Beneath the standards when in position is a plunger L terminating in a roller L'
and which is actuated by a cam M set in motion when the spindle carrying the
toothed block C is caused to engage with the toothed block C by depressing the
lever C³.
The operation of the machine is as follows,
The boot being placed on the jack F, and the dies having been charged with pins
or sprigs and the mould placed thereon into which is now dropped the requisite
number of lifts the attaching standard K is brought under the jack and centred and
the pitch or rake of the jack F having been adjusted by means of the adjusting screw I
the lever C³ is depressed throwing the spindle U into gear with the block C³ which
causes the cam to be revolved thus raising the plunger Land so forcing the attaching
pins from the die through the lifts and bottom leather of the boot and clenching them
against the jack F. The boot is then thrown or "chucked" out of the mould by
tapping the "chucking out" lever P with a hammer or other tool the said lever
operating the "chucking out" rod Q (see Figure 3) or other device for this purpose,
the jack having been previously raised by means of the screw G.
The standard K is now moved to its end of the bed plate and the standard K' in
which the die with beel pins and top pieces has been placed is pushed under the jack.
The boot in the meantime remains upon the jack and the standard K' being provided
with a similar open mouthed mould fitting the top piece is now moved under the
centre of the jack F. The boot is now lowered into the mould and firmly fixed by
the adjusting screw G and the cam again put in motion forcing up the plunger and
driving the heel pins through the top piece into the heel. At the same time the
breasting knife R attached to its stalk S is forced upwards cutting off or breasting
the lifts. The "chucking out" lever is then tapped and the boot thrown out after
the withdrawal of the jack.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
First In a machine for building and attaching the heels of boots and shoes, the
open mouthed mould J substantially as described and illustrated in the accompanying
drawings.
Second: In a machine for building and attaching the heels of boots and shoes the
adjustable jack such as F capable of being regulated to alter the position of the heel
substantially as described and illustrated in the accompanying drawings.
Third The apparatus for building attaching sprigging and breasting the heels of
hoots and shoes substantially as herein described and illustrated in the accompanying
drawings.
