Improvements in Machines for Use in Finishing Boots and Shoes.
I, OWEN ROBINSON, of Champion Works, Kettering, in the County of
Northampton, Engineer, do hereby declare the nature of this invention to be
as follows:-
-
My invention relates to a new machine specially intended for performing the
two operations employed for ornamenting the sole bottoms of, and the faces of the
welts of boots and shoes and known in the trade as bunking and fudging.
I propose to construct my machine somewhat as follows:-I make the frame
or standard in one piece and fit a shaft in it at any convenient part. On this shaft
I mount a driving pulley and also an eccentric to give motion to a slotted lever
(which I will call a rocking lever) and to a slide working in the said slot, the said
lever being supported so that its stroke can be regulated by the operator whilst
working.
At one end the said lever is adapted to carry an adjustable tool holder capable
of being set at varying angles, and having a rotary shaft running in antifriction
bearings and on one end of this shaft fix a wheel with designs on its edge
which designs are intended to be impressed upon the surface of the leather of
the soles or of the welts.
I propose to fix to the standard or the frame of the machine mechanical means
for enabling the operator to hold the boot to the tool or some kind of table to
rest the boot upon in order to make the machine efficient for the purpose for
which it is intended.

Improvements in Machines for Use in Finishing Boots and Shoes.
I, OWEN ROBINSON, of Champion Works, Kettering, in the County of
Northampton 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:
My invention relates to a new machine specially intended for performing the
two operations employed for ornamenting the sole bottoms, and the faces of the
welts, of boots and shoes and known in the trade as bunking and fudging.
According to the invention I construct my machine as follows, that is to say,

page_text: I make the frame or standard in one piece and fit a shaft in it at any convenient
part. On this shaft I mount a driving pulley and also an eccentric or eccentric
pin to give motion to a slotted lever (which I call a rocking lever), the said
lever being supported so that its stroke can be regulated by the operator whilst
working by means of a slide which acts as the fulcrum of the rocking lever.
At one end the said lever is adapted to carry an adjustable tool holder capable
of being set at varying angles, and having a rotary shaft running in antifriction
bearings and on one end of this shaft fix a wheel with designs on its edge
which designs are intended to be impressed upon the surface of the leather of
the soles or of the welts.
I fix to the standard or the frame of the machine mechanical means for enabling
the operator to hold the boot to the tool, or some kind of table to rest the boot
upon in order to make the machine efficient for the purpose for which it is
intended.
In the accompanying drawing:
Figure 1 is a front elevation of a machine for finishing boots and shoes con-
structed according to the invention:
Figure 2 is a sectional side elevation thereof; and
Figures 3 and 4 are a side elevation and a plan of a portion of a work guide
used on the machine.
Figure 5 is a view of a tool used in stitch wheeling or fudging and bunking.
Figures 6 and 7 are a side view and a plan respectively of the top ironing
tool :.
Figures 3 to 7 are drawn to a larger scale than Figures 1 and 2.
a is the main frame or standard made in one piece as above mentioned and b is
an upper frame which is bolted or otherwise suitably secured upon the top of the
main frame or standard a. c is the driving shaft, the said shaft being mounted
in bearings c', cl in the upper frame b and projecting from the said frame at
either end thereof. One of the projecting ends carries a pulley d which is adapted
to be driven by a belt from a pulley de mounted upon a shaft carrying fast
and loose pulleys d, d. The other projecting end of the shaft c carries the
eccentric pin or crank pin e.
f is the rocking lever, suspended upon the collar of the shaft by the
projection e¹, the said lever being provided with a slot fl at its upper part in
which the eccentric pin e engages and also with a slot with which engages
the squared bush h pivotally mounted upon the cylindrical end h¹ of the slide ha
This said slide works in the slot 61 and the recess guide 62 formed in the upper
frame as clearly seen in Figure 2.
With this arrangement it will be obvious that the extent to which the lower
end of the rocking lever f can be vibrated by the eccentric pine when the
shaft c is revolved, can be varied by raising or lowering the slide 3, that is to
say, the pivot around which the lever f vibrates. To effect this adjustment I
mount the slide upon a screw i which engages in an internally screw-threaded
nut or sleevej having a hand-wheel j¹ by means of which it can be rotated. This
internally screw-threaded nut or sleeve is arranged to slide in a hollow
cylindrical portion or guide k formed in the frames a and b, the lower portion ¹
of the said guide being of larger diameter than the upper part and taking a
flange upon the lower part of the internally screw-threaded sleeve j. A
spring is provided inside the enlarged portion of the guide, which spring
normally holds the screw-threaded sleeve j in its uppermost position, that is to say,
with the flange upon its lower end in contact with the shoulder formed at the
junction of the two parts and of the guide as clearly shewn in Figure 2.
The lower part of the screw i is plain and of reduced diameter as shewn at ¹ and
projects through a hole in the lower part of the guide ¹, the projecting end 2ª
thereof being formed with a hole with which engages a hook connected by
means of a rod with a foot lever pivoted at 2 to the frame a of the machine
and adapted to be depressed by means of the operator.

page_text: Before commencing to operate the machine the position of the slide h³ can be
adjusted by means of the handwheel and the extent to which the lower part of
the slotted lever carrying the tool as hereinafter described vibrates, can be adjusted
whilst the machine is in operation by operating the foot lever thereby lowering
the slide this being rendered necessary, for example, when the tool is passing
around the toe of the boot or shoe which requires less movement than when the
tool is passing around the sides of the sole.
is the tool holder, the said holder being pivotally connected to the lower end
of the slotted rocking lever f by means of the bolt so that it can be adjusted to
any desired inclination and be secured at that inclination by means of the nut 1.
m is the rotary tool shaft, the said shaft running on anti-friction rollers n, n
mounted in the lower part of the holder . The front end of this rotary shaft m
is adapted to carry the various tools for the different methods of ornamenting
boots and shoes by bunking and fudging. Such tools are illustrated in Figures 5,
6 and 7, Figure 5 shewing the stitch wheel, (also shewn in position in Figures 1
and 2) and Figures 6 and 7 illustrating a top ironing tool.
For bunking, that is to say, for producing ornamentation upon the underside
of the soles of boots and shoes I employ the guide shewn in Figures 1 and 2,
3 and 4. This guide consists of a curved arm o, the upper or outer end of which
is provided with a rebate o' to receive the edge of the sole. The lower rear part
of the arm is carried and is capable of adjustment in a bracket upon the upper
frame of the machine, it being secured in position in the said bracket by the
thumb screws p', p¹. With this arrangement the boot or shoe sole is held
against the rebate o in the guide and the tool wheel shewn in Figures 1, 2 and 5,
is vibrated upon the underside of the sole held against it, thereby marking it with
the required ornamentation. 2 is a hook secured to the arm o and through which
the finger of the operator is passed to enable him to hold the boot or shoe steadily
against the tool.
()
For fudging, that is to say, for producing imitation stitches upon the upper
side of the sole or welt I employ the table or support shewn in Figures 1 and 2.
This support comprises a bevelled roller q pivotally and adjustably mounted in
a holder secured upon a spindle g² mounted in a socket upon the upper end
of a bracket adapted to slide in a guide formed in the front of the frame a
of the machine. The bracket q is mounted upon an upright rod which runs in
guides, secured to the frame a of the machine and at its lower end rests
upon a foot levers which is pivoted at t and is provided with a pedal at one
end and a counterweight at the other, which said counterweight normally
holds the rod r and bracket g in their uppermost position shewn in Figures 1
and 2; when the pedal is pressed down the rod and bracket fall by their own
weight.
When it is required to use the support g for the boot or shoe to be fudged, it
is turned up into the position indicated in dotted lines in Figure 2, and adjusted
at its proper angle to support the work, the spindle g² being then fixed in position
by the set screw 2°. It will of course be understood that when the support
turned up into the operative position the guide o is slid back or removed.
is
For top ironing I employ the reversible tool illustrated in Figures 6 and 7.
It is adapted to be fitted in the shaft m and one of the parts thereof serves
to iron the sole whilst the face w adjacent thereto serves as a guide for the
side of the sole.
