BOOTS AND SHOES."
Scaled the 7th September 1875, and dated the 30th June 1875.
PROVISIONAL SPECIFICATION left by the said William Jackson at the
Office of the Commissioners of Patents, with his Petition, on the
30th June 1875.
I, WILLIAM JACKSON, of 1ª, Caroline Street, Eaton Square, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "AN IMPROVED MACHINE FOR CUTTING ANd Shaping the SOLES AND HEELS OF
BOOTS AND SHOES," to be as follows :-
My Invention consists in a novel construction and arrangement of
parts of a heel and sole shaping machine for producing the same in a
much cheaper and better manner than hitherto.

page_text: The machine is constructed as follows:-The main or driving shaft
is placed horizontally with a driving wheel to the right, and bevel wheel
to the left, working in communication with a small bevel wheel, which
is attached to an upright rod or shaft. At the lower end is fixed a
round cutter with teeth on the surface, this cutter being of suitable
shape for the heels or soles to be cut. At the lower end of the cutter is
placed a revolving washer, which works in the seam between the hecl
or sole and the upper. The boot is placed on a revolving arm working
from the bed plate in slides to give the required shape to the heel; this
revolving arm being actuated by a wheel in combination with a worm
and shaft, which is worked from the main shaft by a gut or leather
band to give a self-acting movement, and can be disarranged by a clutch
arrangement.
SPECIFICATION in pursuance of the conditions of the Lotters Patent,
filed by the said William Jackson in the Great Seal Patent Office
on the 23rd September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JACKSON, of 1, Caroline Street, Eaton Square, in the County of Mid-
dlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of June, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Jackson, Her special licence,
that I, the said William Jackson, my executors, administrators, and
assigns, or such others as I, the said William Jackson, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED MACHINE
for Cutting and Shaping the SolES AND HEELS OF BOOTS AND SHOES,” upon the
condition (amongst others) that I, the said William Jackson, my execu-
tors or administrators, by an instrument in writing under my, or their, or
one of their hands and scals, should particularly describe and ascertain

page_text: the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Jackson, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawing
forming a. part of this Specification:-
My Invention relates to an improved machine for cutting and shaping
the soles and heels of boots and shoes, and consists in the novel con-
struction and arrangement of the parts of the machine as hercin-after
described.
The principal parts of the said machine are as follows, namely:-A
rotary cutter or knife, an adjustable rotating post for supporting a boot
or shoe while it is subjected to the action of the said cutter, a peculiar
device for securing the boot or shoc upon the post, and mechanism for
rotating the said post, and for stopping its rotation without stopping the
rotation of the main shaft and the cutter.
My said Invention is illustrated in the recomanwing Drawing which

page_text: frame A. This shaft has on it a bevel pinion e, which is geared with
the aforesaid bevel wheel c. At the lower end of this shaft d I fix tho
cutter, as clearly shown in Figure 1. Below the said cutter I place
the washer g, whose edge projects far enough to work in the seam
between the "upper" and the heel or sole of a boot or shoe placed in the
said machine, as clearly shewn in Figure 4. This washer turns loosely
or independently of the cutter. The said cutter and washer are securely
held
upon the said shaft by a nut h or any other suitable device, which
will permit the cutter to be readily removed and replaced, so that I may
exchange one cutter for another without delay when required. i is
the post or arm which supports the boot or shoe, whose sole or heel is
being shaped. This post is fitted to turn in a bearing in the sliding
plate j, which works between the guides & that are screwed upon the
bed of the frame A, the said plate and guides having their edges
dovetailed, and one of the said guides being made adjustable laterally
by means of screws k¹ or other suitable means to allow it to be adjusted
to the plate when required. m is a lever for adjusting or setting the
post nearer to or farther from the cutter f; m³ is a screw passed
through the said lever with its point resting on the guide plate below it.
By means of this screw I adjust the post vertically to any required
position. is a spring tending to keep the said post away from the
cutter when the said lever is released. The disc or block at the top
of the post is preferably roughened on its upper surface, and it is
secured by a screw or by other means, which permit it to be readily
removed and replaced. o is a clamping arm or lever, whose fulcrum is
at o* in the bracket p, which is fixed or formed on the post i. The said
arm o is provided with an adjusting clamp screw o¹, between which and
the block the boot or shoc is held while being operated upon. The
outer extremity of the arm o is provided with an eccentric handle o²,
whereby the said arm is casily made fast and released to allow the boot
or shoc to be readily and conveniently put upon the post i secured
thereon, and removed when finished. q is a worm wheel fixed on the
post i, and geared with the worm r, which turns in the bearings 3 fixed
on the plate j. The shaft of this worm carries a pulley 8, which is
geared by a belt or band with the pulley t on the main shaft a. This
pulley is arranged in combination with the sliding disc u, which is
provided with pins or studs u' arranged to enter holes in the pulley t, when
the disc u is pressed against the said pulley. This disc is fitted to slide
on a feather or key u* on the shaft a, so that it will slide endwise on the

page_text: said shaft, but is compelled to turn with the same. v is a lever, whose
fulcrum is at v¹, and which has at its cnd v² a pin or stud that projects
into the groove or channel in the periphery of the disc u. By means
of this lever the said disc is moved into or out of connection with the
pulley t.
In using my improved machine the boot or shoc is placed on the
post i and secured thercon by the clamping lever o. Then the said post
is adjusted by means of the lever m and secured by the screw m¹ in the
proper position for the cutter f to act on the sole or heel of the said
boot or shoe. The post i having been turned into the proper position
to commence cutting, the disc 24 is moved into connection with the
pulley t. The driving shaft a and cutter continually rotating, motion
is communicated by the belt or band to the worm r, and from this worm
to the worm wheel 9, whereby the post i with the boot or shoe thereon
is rotated. As it rotates the rapidly revolving cutter fcuts and shapes
the surface of the solc or heel, and as the post arrives at a position
opposite to that in which it was first adjusted the disc u is drawn out
of connection with the pulley . The post can then be turned back by.
rotating the pulley 8, the clamp arm is slackened, the boot removed
from the said post, and another one placed thereon; the above operations
being repeated without stopping the driving shaft a.
In some instances I so arrange the lever that it is acted on by a
projecting arm or rod on the post i or bracket p, or by other suitable
means to effect the adjustment of the lever o automatically, so that the
machine will be self-acting with regard to this part of its operation.
In Figure 5 I have illustrated an automatic devico to be used in
shaping heels with square fronts. This device consists of a cam or
template w fixed on the post i, and a lever w¹ whose fulcrum is at w* on
the plate k. The said lever has an antifriction roller 20³, against which
the edge of the cam w works. This cam as it rotates with the post
causes the latter to so adjust itself to the cutter as to give automatically
the required shape to the heel. The said lever is formed with a slot at
o, through which is passed a screw w³, whereby the said lever and
roller can be secured in any required position, according to the shape or
size of the heel.
The chief advantages of my improved machine are as follows, namely:

the year of our Lord One thousand eight hundred and seventy-
five.
