Improvements in or relating to Cutters for Paring the Edges of the
Soles, Waists, and Heels of Boots and Shoes.
We, HARRY WALKER, of the Firm of Messieurs Harry Walker and Son, of
Airedale Shoe Factory, Washington Street, Leeds in the County of York Boot
and Shoe Manufacturers, WILLIAM ELLIS, of 147 Burley Road Leeds aforesaid
Foreman Mechanic in the employ of the said firm, and NATHAN ELLIS, of
133 Burley Road, Leeds aforesaid, Manager for the said firm, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in cutters such as are employed on
machines rotating at a high speed for paring or trimming the edges of the soles and
heels of boots and shoes.
Hitherto ordinarily two separate cutters or tools have been employed for paring
the edges of the sole and heel, and for cutting or slightly chamfering the upper
edge of the sole and heel, and which operation is known in the trade by various
names, such as "taking the welt out or "ploughing" or "bitting."
"
Now the object of this invention is to construct a cutter which is capable of
"taking the welt out" at the same time that the edge of the sole or other part of
the boot and shoe is being pared or trimmed, thereby saving time and labor.
According to this invention the cutter is constructed with blades, either let into
a boss or cut out of a block. The blades are provided with cutting edges, and each
alternate or any desired number of the blades on the guard side thereof is provided
or arranged with a projection or cutting edge which is shaped to the exact contour
of the piece to be cut away from the upper or welt side of the sole or other part of
the boot or shoe.
By arranging these projecting cutting edges on each alternate blade or with a
great space between them, the blades without the projections are employed for
removing any irregularities left by the blades armed with projections and thereby
more perfectly trimming the edge operated upon.
Cutters constructed as above described may be used with the guard usually
employed for protecting the upper from damage and they may be mounted on the
spindle of the machine in the ordinary manner.
The above described cutters may be employed for removing the "bits" from the
upper portion of the seat, waist, and forepart of a boot or shoe at the same time
that the edge of the sole or heel is being pared or trimmed.

the nature of this invention and in what manner the same is to be performed,

This invention relates to improvements in cutters such as are employed on

and heels of boots and shoes.
Hitherto ordinarily two separate cutters or tools have been employed for paring
the edges of the sole and heel, and for cutting or slightly chamfering the upper

taking the welt out.

Now the object of this invention is to construct a cutter which is capable of
"taking the welt out at the same time that the edge of the sole or other part of
the boot and shoe is being pared or trimmed thereby saving time and labour.
In the drawings:-
Fig. 1. is a front elevation,. Fig. 2. an elevation drawn at a right angle to Fig. 1.
Fig. 3. a sectional elevation Fig. 4. a back elevation Fig. 5. an elevation drawn at
a right angle to Fig. 4 of a cutter constructed according to this invention.
Fig. 6. a sectional elevation of the guard usually employed with cutters of this
description.
Fig. 7. an elevation of the improved cutter and its guard mounted upon the shaft
of the paring machine taken from the back of the machine.

According to this invention the cutter is constructed with blades B, either let
into the boss C or cut out of a solid block. In the drawings the blades B are
shown let into the boss C, provided with a parallel or tapering hole c.
blades B are provided with cutting edges b and each alternate, or any desired number
of blades on the guard side of the cutter is or are provided or arranged with a pro-
jection or projections D provided with cutting edges hereafter termed projecting
bitting edges which is or are shaped to the exact contour of the piece to be cut
away from the upper or welt side of the sole or other part of the boot or shoe. In
the drawings the projecting bitting edges D are shown on each alternate blade B,
so as to leave a blade without a projection between the projections which is the
form in which we prefer to use them, but if desired these projections might be
arranged on every third, fourth, or more blades so as to leave two, three, or more
blades between the projecting or bitting edges.
By arranging these projecting bitting edges D on each alternate blade, or with a
greater space between them the blades B' without the projections are employed for
removing any irregularities left by the blades armed with the projections. By this
means the edges of the soles are more perfectly trimmed than if a cutting pro-
jection D was provided on every blade.
Cutters constructed as above described may be used with the guard E usually
employed for protecting the upper from damage and they may be mounted on the
spindle F of the machine in the ordinary manner.
The above described cutters may be employed for removing the "bits" from the
upper portion of the seat, waist, and forepart of a boot or shoe at same time that
the edge of the sole or heel is being pared or trimmed.
One, two, or more cutters of the same or varying diameters may be mounted
upon the spindle F at the same time as is frequently done with the ordinary
cutters.
The boot or shoe to be operated upon is held in the operator's hands and applied
to the action of the cutter in the usual manner.
We would have it understood that we are aware that rotary cutters provided
with cutting edges of various contours, each and every blade, being of the same
contour have been previously used but to such cutters we lay no claim.

page_text: Having now particularly described the nature of this invention and how the
same may be carried into practice, we declare that what we claim is :-
1st. The improvements in or relating to rotary cutters for paring the edges of
the soles, waists, and heels of boots and shoes which improvements consist in
arming a portion of the cutting blades with a projecting cutting or bitting edges
for "taking the welt out" at the same time that the edge is being pared.
2nd. A rotary cutter for paring the edges of the soles, waists, and heels of boots
and shoes, substantially as herein described and illustrated, having every alternate
blade or any number of blades, armed with projecting cutting edge, for "taking the
welt out," the intervening blades being plain for removing irregularities as
set forth.
3rd. The combination in a rotary cutter for paring the edges of the soles waists,
and heels of boots and shoes of the blades B armed with projecting cutting
edges D, having one, or more plain blades B', arranged between them, said blades
being let into or formed out of the boss C, all substantially as and for the purposes
set forth.
