PROVISIONAL SPECIFICATION.
New or Improved Machinery for Making Heels for Boots
and Shoes.
I, JOHN VEASY COLLIER, of Harleston Road, Northampton, in the County
of Northampton, Boot and Shoe Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention consists of the hereindescribed new or improved machinery for
making heels for boots and shoes whereby there is a considerable saving of labour
thus reducing the cost of manufacture. Moreover, all the heels of a certain size
can be built to a uniform height and the split lift can be built in the heel with the
other sections instead of being nailed on to the bottom after the heel is built.
In carrying out this invention I provide one, two, three or more moulds which
are shaped to receive the various sections of the heel and are mounted on the bed
of the machine and suitably guided so as to be moved to and fro. Above each of
these moulds I provide a pressure block which is adapted to move up and down
and is suitably guided by the framework of the machine. The bottom of each of
these pressure blocks is made of a shape to correspond with the seat of the boot
upon which the heel when built is to be fixed. The said pressure blocks are or
may be moved upwardly by a spring or counterweight or other means and when
depressed as hereinafter described on to the top of the sections of the heel in the
mould the pressure block is kept in this position as long as is required by a ratchet
engaging with the teeth in the frame of the machine or by, other suitable device.
Above each of the pressure blocks there is a plunger suitably guided and moved
up and down by means of a crank shaft or cam shaft. Between the bottom of
each of the plungers and the top of each of the pressure blocks there is a sliding
distance block preferably made taper which can be inserted between the bottom
of the plunger and the top of the pressure block so that the plunger will then act
upon the latter and force it down. Or the said slides can be drawn forward so
that the plungers will then not act upon the pressure blocks.
The machine above described is used as follows:-The various lifts or sections
of which the boot heel is to be made are placed in one of the moulds say the first
mould each lift being slightly covered with paste or other adhesive mixture. This
mould with the heel sections in it is then moved forward so as to be immediately
under the pressure block, the exact position of the mould being regulated by a suitable
stop. The sliding block is then inserted between the plunger and the top of the
pressure block so that the plunger then forces the pressure block down on to the
sections in the mould and the pressure block is held in this position by means of
the catch or ratchet or other device as long as is necessary. The operator then
places the lifts of another heel in the second mould and compresses them by the
second pressure block as above described. He then similarly forms another heel
in the third mould and compresses it by the third pressure block. The first
pressure block can now be released from the first mould and allowed to move
upwardly by its spring or counterweight or other device the distance block between
the pressure block and the bottom of the plunger having been removed.
mould is then drawn forward and the heel removed, and sections or lifts for forming
another heel are placed therein and compressed as above described, and so on each
heel being properly compressed while two other heels are being built.
This

page_text: It will be seen that as the pressure is applied by power and is continuous the
pressure is equal on each heel and therefore those of the same size can all be built
to a uniform height.
It will be evident that if desired the machine may be constructed with only one
two or more than three of the moulds and corresponding pressure blocks and
plungers without departing from the nature of my invention.

New or Improved Machinery for Making Heels for Boots
and Shoes.
1, JOHN VEASY COLLIER, of Harleston Road, Northampton, in the County of
Northampton, Boot and Shoe Manufacturer, 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 consists of the herein-described new or improved machinery for
making heels for boots and shoes whereby there is a considerable saving of labour
thus reducing the cost of manufacture. Moreover, all the heels of a certain size
can be built to a uniform height and the split lift can be built in the heel with the
other sections instead of being nailed on to the bottom after the heel is built.
I will describe my invention by referring to the accompanying drawings on
which
Fig. 1 is a front sectional elevation of a boot and shoe heel making machine
constructed according to this invention; Fig. 2 is a sectional side elevation of the
same on line X X of Fig. 1; Fig. 3 is a sectional side elevation of the same on
line Y Y of Fig. 1;
Fig. 4 is a front elevation and plan of one of the pressure blocks of the said
machine;
Fig. 5 is a front elevation and plan of one of the distance blocks of the said
machine;
Fig. 6 shews a part of one of the said pressure blocks in front and side elevations
and in plan;
Fig. 7 is a plan of one of the heel moulds of the said machine; and
Fig. 8 is a plan of one of the treadles of the said machine.
The same letters and numerals indicate the same parts throughout the drawings.
The said machine is constructed and operated as follows:-A is a machine bed
suitably supported as by the legs a¹ a². Fixed to the bed A are four standards
marked BB2 B3 B4 provided with top bearings 61, 62, 63, 6 in which revolves the
three throw crank shaft C provided with fly wheel c' and driving pulleys
D1 D2 D3 are three plungers guided for vertical movement by the guides E E E³
fixed to the standards B B2 B3 B. These plungers are connected to the three
throw crank shaft C by the connecting rods F1 F2 F3 which at their top ends f
are respectively jointed to the throws of the crank shaft C and at their lower
ends are respectively jointed to the plungers D' D' D³. Thus so long as the
machine is at work the plungers D1 D2 D3 are moving up and down continuously.
Mounted so as to be capable of sliding to and fro upon the bed A are three heel
moulds G G2 G3 which are each shaped internally at g' to correspond with the
shape of the sides of the required heel so as to receive the various sectious of

page_text: a*
I'
which the heel is built up. Each of these moulds is guided by two planed strips aa
cast on the bed A and between which the mould will slide. Under the
plungers D' D' D' and above the moulds G' G' GI provide the three pressure
blocks H H H which are arranged for vertical movement by fitting on the two
upright studs II fixed to the bed A of the machine. Upon each of the studs 111
is a coiled spring J which springs are strong enough to raise and maintain the
pressure blocks in their highest positions against the nuts on the top of the studs.
Each of the pressure blocks H H H has a removable projecting lower part 4' adapted
to fit into the corresponding mould and press on to the heel therein. The underside
of the projecting part 4' is made of a shape to correspond with the seat of the boot
upon which the heel when built is to be fixed. On the top of each of the
pressure blocks H'H'H' there is a sliding distance block which are marked
respectively K' K' K and are adapted to slide in guides formed on the top of
the pressure blocks. For each of the distance blocks K' KK I provide means
for pushing the distance block forward between the bottom of the corresponding
plunger and the top of the pressure block so that the plunger will then act upon
the distance block and force it and the corresponding pressure block down. The
means for operating the distance blocks consist of three treadles marked
respectively L L L one for each distance block turning on a fulcrum shaft
and continued beyond the same as an arm which by means of the connecting
rod is connected to the arm of a bell-crank lever which turns on a fulcrum
pin and the other arm of which has a pusher piece connected to it so that
when the trendle is pushed down the pusher piece will move forward and push
the corresponding distance block underneath the plunger. Each of the said
distance blocks K K'K' has a coiled spring m¹ connecting it to a bracket mon
the machine frame so as to draw the distance block back from underneath the plunger
at the proper times as hereinafter described.
Each of the three pressure blocks HH2 H3 is provided with two downwardly
projecting ratchets or catches 4 Awl ich at 4 are jointed to the pressure block
and near their lower ends each is made with a notch . These catches pass
through holes in the bed A and at their lower ends are connected together by a
coiled spring so that when the pressure block has been forced down to compress
the boot heel in the mould as hereinafter described, the notches will engage
underneath the bed A and thus maintain the pressure block in its lowest position..
In order to release the catches A to allow the springs J to raise the pressure
blocks, I provide for each pair of catches two small bell-crank levers n' n³ which
by the rods are connected to the shorter arm of the corresponding treadle
lever N N or N³ which turn on the fulcrum so that when one of these
treadle levers N' N2 N3 is depressed the shorter arm of the lever together with
the two connecting rods a jointed thereto rise and turn the bell-crank
levers n' n² so as to force the catches farther apart as shewn on the right
hand side of the machine Fig. 1 so that the notches will then be free of the
bed A. and the pressure block will rise.
The machine above in part described acts as follows:-The various lifts or
sections o of which the boot heel is to be made are placed in one of the moulds say
the first mould G' each lift being slightly covered with paste or other adhesive
mixture. The mould G' will then be in the position in which the mould G' is
shewn in Fig. 3. The mould G with the heel section o in it is then slided back
along the machine bed A until it comes in contact with the screwed adjustable
stop p at the back of the machine when the mould G' will be immediately under
the pressure bluck H' the exact position of the mould being regulated by the stop p.
The workman now depresses the treadle L' causing the pusher piece to push
the distance block K' under the plunger D' so that this plunger descending acts
upon the distance block K' and forces the pressure block H' down so that its
lower projecting part & acts upon the sections o in the mould G', and the pressure
block is held in this position by means of the catches engaging under the bed
plate A as shewn in Fig. 1. The operator now places the lifts of another heel in

page_text: the second mould G' and slides this mould under the plunger D' and depresses the
treadle L' so as to insert the distance block K' under the plunger D' which will
then depress the pressure block H' and compress the sections in the mould G'as
sbewn in Fig. 1. The operator then similarly forms another heel in the third
mould G and depresses the trendle L so that the heel in the mould G is
compressed by the pressure block H' similarly as above described with reference
to the other two pressure blocks.
Immediately the plunger D' has acted upon the distance block K' and depressed
the pressure block H' as above described so that the catches h h catch underneath
the bed A and the plunger has commenced to rise, the spring m¹ draws back the
distance block K so that the moving plunger does not continue to act upon the
pressure block after it has been secured in its lowest position by the catches.
The first pressure block H' can now he released from the first mould G by the
operator depressing the treadle L' which as above described throws outwardly the
catches free of the bed A and allows the pressure block H' to rise. The
operator then draws mould G₁ forward to the position shewn by the mould Gin
Fig. 3 and the heel o is removed from the mould, and sections or lifts for another heel
are placed therein and the mould G' is slided back underneath the pressure block H¹
and the heel is compressed as above described and so on each heel being properly
compressed whilst two other heels are being built..
In order to facilitate the removal of the finished heel from the mould I may
provide for each mould a lever such as Q which turns on a fulcrum gl at the front
of the machine and has a piston q2 jointed to one of its arms q immediately
underneath the cavity g' in the mould, so that when the lever Q is depressed the
pusher g will be raised and push the finished heel out of the mould.
Each of the treadles L L L is provided with a coiled wire spring 18 connected
to the bed A of the machine for lilting the treadle after it has been depressed,
and the treadles N' N N are similarly provided with springs n for lifting
them.
It will be seen that as the pressure on the lifts of the heel is applied by po ver
and is continuous the pressure is equal on each heel and therefore those heels
which are nominally of the same height can all he built to a uniform height.
It will be evident that if desired the machine may be constructed with only one
or two or with more than three of the moulds G¹ G G³ and corresponding pressure
blocks and plungers and accessories without departing from the nature of my
invention.
I wish it to be understood that I do not limit myself to the precise details
herein described and illustrated by my drawings as it will be evident that they
may be varied to some extent without departing from the nature of my invention.
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 :-
1. In a machine for making heels for boots and shoes the employment of a heel
mould adapted to slide to and fro on the bed of the machine, the pressure block
guided for vertical movement above the said mould, catches for maintaining the
pressure block in its lowest position, springs or like means for raising the said
pressure block, a plunger and means for moving the plunger up and down above
the pressure block, and a distance block with means for inserting the same between
the plunger and the pressure block to cause the plunger to depress the pressure
block and compress the heel in the mould, all substantially as hereinbefore
described.
2. In a boot and shoe heel making machine such as denoted by Claim 1, the
combination with the heel mould of the pressure block such as H', for compressing
the heel, catches A secured thereto for holding the pressure block in its lowest
position, treadle and connections for releasing the said catches, and the springs for

page_text: causing the pressure block to rise out of the mould, all substantially as herein before
described.
3. A boot and shoe heel making machine constructed arranged and operating
substantially as hereinbefore described and illustrated by the accompanying
drawings whether the said machine is made to work with only one or with two
three or more of the heel moulds and accessories, substantially as set forth.
