Improvements in or relating to Boot Finishing Machinery.
I, WALTER JACKSON, of Belgrave, in the County Borough of Leicester,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to boot finishing machinery and has for its
principal object to produce a machine, which, by the mere change of tool, can
be used for the whole or nearly the whole of the finishing processes of the sole
and heel of a boot or shoe, thereby effecting a great reduction in the number of
machines required for these purposes and a corresponding saving to the manu-
facturer who, as frequently occurs, has not sufficient work to keep any one of
the said finishing machines fully employed.
The invention also embodies other features including an improvement in
the construction of certain finishing tools the nature of which will be herein-
after described.
A machine constructed according to this invention may be used for bunk-
ing, stitch wheeling, seat wheeling, stitch pricking, edge setting.
My improved machine comprises a shaft running in bearings on the upper
part of a pedestal, standard, or bed plate and driven by a pulley on or near
the centre of the shaft. On each end of the shaft is an eccentrically actuated
head to which the tool stock or holder is attached by a screw or equivalent means
so as to partake of the rocking motion of the head which reciprocates prefer-
ably in an arc of a circle. The tool holder is furnished with a tubular passage
to receive the shank of any of the finishing tools hereinbefore mentioned and
the said holder is provided with a rectangular groove into which the tool fits
snugly so that it cannot move independently of the holder.
On one side of the holder a lever is fulcrummed, having at one end a pin
projecting through an opening in the wall of the holder into the tubular pas-
sage before mentioned so as to enter a groove in the shank of the tool and
prevent the latter dropping out of the holder when inserted therein.
A spring is located under the other end of the lever and is arranged to keep
the before mentioned pin normally projecting into the groove in the tool shank.
When it is desired to change one tool for another, the spring-controlled end
of the lever is depressed so as to withdraw the pin on the opposite end from the
groove in the tool shank and flush with the side of the passage so that the tool
can be removed.
The invention also includes an improvement in seat wheels, the novelty of
which resides in the same being constructed in sections which enables the wheel
per se to be re-cut when worn.
According to this part of the invention the guard and the narrow distance
piece between it and the wheel may be formed integrally with a tube or sleeve
of smaller diameter on the exterior of which the wheel may be fitted and fixed
in position thereon by a lock nut screwed on one end of the sleeve.
By preference the part of the sleeve over which the seat wheel fits is left
smooth so that the seat wheel is merely slid thereover, but is bored so that it is

page_text: a true fit, and the end portion of the said sleeve may be screw threaded to receive
a preferably circular nut which locks the seat wheel in position.
The complete sectional seat wheel may then be passed over a circular pin pro-
jecting from a square or enlarged foot to the shank and secured in position
thereon by a nut.
The invention also includes a rotary tool of peculiar formation for the pur-
pose of stitch pricking which is usually effected by a vertical rising and falling
tool.
The improved tool is formed with teeth inwardly curved or having a concavity
in the centre so that when a boot welt or sole edge is applied thereto it forms a
deep impression at each side of the stitch and leaves a bold stitch in the centre
which much improves the appearance of the work.
A further part of the invention relates to an improved construction of work
support specially adapted for use when presenting the toe of a boot or shoe to
the bunking tool.
The said support comprises a swing or revoluble arm carrying at one end on
its underside a supporting pin fitting rotatably in the open upper end of a
spring controlled spindle located in a sleeve provided with lugs or otherwise
arranged for attachment to the framing of the machine.
A screwed sleeve passing into the end of the herein before mentioned sleeve
is employed to adjust the tension of the spring.
The end of the said spindle passes through and out of the ends of both
sleeves and is connected by a wire rod, chain or equivalent to a foot pedal.
The other end of the revoluble arm carries a vertically adjustable shouldered
pin open at the top to receive the shank of the toe rest which comprises a shaped
plate covered with leather indiarubber, or the like to receive the toe of a boot
or shoe when the said toe is to be presented to the finishing tool.
When other parts of the sole than the toe are being submitted to the tool the
said arm and work support are swung aside out of the way. The edge of the
sole is kept pressed by the operator against a revoluble disc or guard while
being acted upon by the tool.

Improvements in or relating to Boot Finishing Machinery.
I, WALTER JACKSON, of Belgrave, in the County Borough of Leicester,
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:
This invention relates to machines employed in the finishing or ornamenting
of the soles and heels of boots and shoes and will be understood from the fol-
lowing description in reference to the accompanying drawings, in which,
Figure 1 is a plan, and
Figure 2 a side elevation of a machine constructed in accordance with this
invention.
Figure 3 is a longitudinal section of the tool holder with my improved seat
wheel attached thereto.
Figure 4 is a similar section of part of the holder with a rotary bunking tool
attached.

page_text: Figure 5 is a central vertical section of my improved seat wheel.
Figure 6 is a section of an alternative tool holder.
A represents the bed plate which may be mounted on a bench or suitable
standard or pillar. Arising therefrom are two arms A' A² carrying bear-
ings A³ A for a driving shaft B which has a driving pulley C located centrally
thereon.
Each end of the shaft carries a crank pin B or equivalent Figure 2 passing
into a head 1) which is also provided with a tubular passage or sleeve 1 fitting
loosely over a pin or fulcrum A projecting from one of the arms A' A³ and
secured in position thereon by a set screw A.
As the shaft revolves, the crank pin 13 causes the head D to reciprocate
rapidly in an arc of a circle.
To the lug 18 depending from the head D there is connected by a screw D³
a tool stock or holder E which partakes of the rocking motion of the head.
Each tool holder is provided with a tubular passage E Figure 3 to receive
the shank of the finishing tool, the said shank being formed in either one or
two parts.
For convenience of changing the tool the shank is formed in two parts F FI
the longer part F being located in the tubular passage E' of the holder E and
the shorter part F (which is formed integrally with the tool itself) is let into
the socketted end of the larger part F and maintained in working position by
a lever G having a pin or tongue G₁ on its end projecting through an open-
ing in the side of F and entering a circumferential groove in the short shank F
so that, as shown in Fig. 4, the tool is free to revolve when a boot sole is applied
thereto but is prevented falling or being drawn out of its holder.
When the shank is formed in one piece and of such a length as to pass through
the tubular passage in the holder E, the tongue on the end of the lever G passes
through the wall of the holder E and into a groove in the tool shank.
The said lever is fulcrummed at G2 to the holder and has a spring G3 bearing
under its opposite end so as to keep the tongue normally projecting into the
groove in the tool shank.
When it is desired to change one finishing tool for another the spring end of
the said lever G is depressed so as to withdraw the tongue from the groove in
the tool shank and flush with the side of the passage so that the tool can be
removed.
When the tool shank is made in two parts, as shown most clearly in Figure 3,
it may have a nut and washer F F on its screwed end to prevent it being drawn
through the holder; it may also be provided with a screw F+ located in a slot E2
in the holder and a spring F encircled around it to permit it a certain amount
of controlled backward movement in the holder due to pressure on the tool.
Referring to Figures 1 and 2.
H represents a rotary stitch wheel tool capable of revolving freely in its
holder when the edge of a boot sole is applied thereto in the usual manner
and J is the work support upon which the edge of the sole is placed. This
support is constructed in accordance with my prior Patent No. 11,624 of 1898.
The rotary tool K at the opposite end of the machine is for bunking and is
used in combination with a work rest or support of an improved construction
as hereinafter described.
The improved work support comprises a toe rest consisting of a shaped plate L
covered with leather, india-rubber, or the like, to receive the toe of a boot or
shoe whose sole is being presented to the bunking or finishing tool in the well
understood manner.
The said toe rest is provided with a shank L' fitting rotatably into the open
upper end of a shouldered pin L2 carried by a swing arm hereinafter described
and adjustable vertically relatively to the tool K by a set screw L³ passing
through the said arm so as to bear against the said pin L².
The swing arm comprises a horizontally movable spring governed rod M

page_text: passing through a sleeve M¹ each being shouldered at M2 to prevent the rod
going too far into the sleeve. The end of the said rod projects out of the said
sleeve and is encircled by a spiral spring M³ to permit the toe rest to be drawn
forward somewhat and to increase the scope of its movement relatively to the
bunking tool K which is more or less necessary according to the shape of the
toe (square or pointed) being treated.
•
The swing arm has a circular movement relatively to the tool K for which
purpose it is furnished at one end with a pin M depending from the sleeve M¹
and fitting rotatably in the upper end of a spindle N contained within a sleeve ()
and shouldered at N₁ to rest on a spring P supported by a wing nut R screwed
into the bottom end of the sleeve and the turning of which regulates the
power of the spring.
The spindle N is formed with a flat or recess №2 into which the end of a
screw S enters to limit its up and down movement.
A cord or wire N³ inay be connected to the spindle N and the other end to a
foot pedal (not shown) to facilitate lowering the said work support when desired
by the foot of the operator.
The sleeve is provided on each side with a lug 01, Figure 1, by which it is
fixed to the bed plate A by screw bolts 0²
A spiral spring T connected one end to the framing A and the other end to
the swing arm M¹ draws the latter to one side when not in actual use.
During the bunking operation the edge of the boot sole is kept pressed by
the operator against a revoluble disc or guard X carried loosely on the end of
an arm fitted into the framing of the machine.
The invention also includes an improved heel seat wheel the novelty of which
resides in the same being constructed in sections which enables the wheel per se
to be re-cut when worn.
Referring to Figures 3 and 5,
with the narrow distance piece U
integrally with a tube or sleeve U
the wheel may be fitted and fixed
on one end of the sleeve.
U represents the usual guard which together
between it and the wheel V may be formed
of smaller diameter on the exterior of which
in position thereon by a lock nut W screwed
By preference the part of the sleeve over which the seat wheel fits is left
smooth so that the seat wheel is merely slid thereover but is bored so as to be
a true fit, while the end portion of the said sleeve is screw threaded to receive
the preferably circular nut W which locks the seat wheel in position.
The complete sectional seat wheel may then be passed over the end of the
shank up to a collar or enlargement F7 thereof and be fixed in position by
a nut Fo
It will be observed that by simply depressing the spring controlled end of
the lever Gone of the said finishing tools can be removed from its holder and
another readily fitted in its place.
If desired the holder illustrated in Figure 6 and constructed according to my
prior Patent No. 11624 of 1898 may be employed instead of the holder E.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a boot finishing machine the combination of a shaft, an oscillating head
on each end thereof, a tool stock or holder connected to each head, a stitch
wheel tool attached to one holder and a bunking tool attached to the other
