I DAVID PICKLES of Queens Road, Halifax, in the county of York, Clogger, do
hereby declare the nature of this Invention to be as follows:-
The object of my invention is by a new construction of knife to save waste in
cutting out leather and other substances, also to cut a greater quantity at once than
by the ordinary knives.
I construct my knives of thin sheet steel of even thickness shaped to the required
form and hardened and tempered, and filled in or strengthened with wood, iron,
composition or other substance, the cutting edge may be made by sharpening from
one or both sides the ordinary knives are made with edges bevelled from the outside
and when cutting out waste strips of leather about one inch in width between each top
or back, and can only cut through one or two thicknesses at once, whilst my knives
will cut through six or more and leave no waste and are of a much cheaper
construction.

Improvements in Press Knives for Cutting Boot Uppers, Fronts,
Baoks, and other Shapes.
I DAVID PICKLES of Queens Road, Halifax in the county of York, Clogger 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:
The object of my invention is by a new construction of knife to save waste in
cutting out leather, cloth, or other substances, also to cut a greater quantity at once,
than by the ordinary knives.
Fig. 1 is a plan of knife for cutting half backs for clogs or boots.
Fig. 2 is a plan of knife for cutting clog or boot uppers.
Fig. 3 is a plan of knife for cutting backs.
Fig. 4 is a plan of knife for cutting soles.
Fig. 5 is a section of Fig. 1 on the line A. B.
Fig. 6 is a section of Fig. 2 on the line A. B.
Fig. 7 is a section of Fig. 3 showing punches for making lace or button holes.
I construct my knives C of thin sheet steel of even thickness, shaped to the required
form, and hardened or tempered, and filled in or strengthened with wood iron,
composition or other substance to form the back or foundation D, the cutting edge
may be made by sharpening from one or both sides.
The various knives are placed in numbers as close together as possible (in the press)
upon the sheets of leather or other substances to be cut, the press is brought into
action and the knives cut the sheets of leather into the various shapes required, with
little or no waste between the knives.
The knives are secured to their blocks or foundations D, by screws E, or by other
suitable means. The ordinary knives are made with edges bevelled from the outside,
and when cutting out leave waste strips of leather or other substance about one inch
in width, between each top or back, whilst my knives will cut through six or more,
and leave little or no waste and are of a much cheaper construction.
The lace holes, button holes, and other fancy or irregular shapes may also be cut
out at the same time by fixing a series of punches F, of the required shape at the
required points on the body or solid portion of the knives.
Also the sole cutting knives (see Fig. 4) may be provided with small studs or
centres screwed or fixed in the block or foundation of the knives, so that as each
sole is cut it is also marked where each revit and nail is required, this has hitherto been
done by hand.

page_text: Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed I would have it understood, that I
do not limit myself to any shape of knives, but I declare that what I claim is :-
Knives made of thin steel and filled in with blocks or foundations of various
shapes (with or without the punches or markers) as and for the purposes shown and
described.
