[Communicated from abroad by WILLIAM BENNETT ARNOLD, of Massachusetts,
United States of America, Manufacturer.]
I, HERBERT JOHN HADDAN, of 67 Strand, in the County of Middlesex, Civil
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:-
In the accompanying drawings
Fig. 1 is a bottom view of a shoe or boot, having its outer sole sewed to the insole
and upper by thread of the improved kind to be described.
Fig. 2 is a similar view of a shoe or boot having its welt, for connecting its outer
sole to the inner sole and upper, sewed to such insole and upper by the said thread.
Fig. 3 is a side view exhibiting one mode of constructing the compound thread used
in the shoe as described.
Fig. 4 is a view of a piece of the corrugated wire employed in making such
compound thread-the said Figs. 3 and 4 being on an enlarged scale.
Fig. 5 is a transverse section of a shoe, showing the outer sole connected to the
welt by a compound thread, composed in part of one or more wires corrugated length-
wise, as hereinafter explained.
The object of the improvement, the nature of which is defined in the claim or claims
hereinafter presented, is to combine with the shoe or boot, and the usual thread or
waxed end used in connecting together parts thereof, a corrugated metallic wire or
wires introduced into the said thread; the introduction being effected either by
twisting or braiding the wire or wires, and the thread, together, or by winding the
thread about the wire or wires. The corrugations of the wires prevent the thread
from slipping on the wire or wires, while it is being used-especially while being
sewed into the shoe by means of a McKay Sewing Machine. And furthermore, the
corrugated wire effects a degree of elasticity to the compound thread, and also to the

page_text: shoe, in the parts thereof in which such compound thread may be, that operates to
prevent the thread from becoming ruptured or broken, while the shoe or boot may
be in usc.
Thus it will be seen that not only is the thread much improved for being used,
especially in a sewing machine, but the shoe or boot, or part or parts thereof sewed by
it, have in consequence thereof, an elasticity or flexibility that is advantageous as
specified.
In Fig. 1 the sewing of the outer sole A, and the insole C and the upper D, is
shown at s, the compound thread used in effecting such being composed in whole or
in part of one or more metallic wires a, each corrugated lengthwise of it, and one or
more threads or yarns of a fibrous, vegetable, or animal material, braided, twisted, or
intertwisted with the said wire or wires or twined or wound about such. The thread
so made may have, or generally has, a covering of shoe-makers wax applied to it.
So in Fig. 2, the sewing of the welt B to the insole C and upper D is represented at s
it being done with the compound thread composed in part of the corrugated wire.
In Fig. 5, the outer sole is shown at A, the welt at Binsole at Cand the upper at D;
the sewing of the welt to the outer sole by the compound thread, being shown at
such thread being composed in part of corrugated wire, as described.
I do not herein claim broadly a boot or shoe having its outer sole, or the welt
thereof, sewed to the insole and upper with thread composed in part of a wire or
wires not corrugated lengthwise, but
Having now particularly described and ascertained the nature of said invention
and in what manner the same is to be performed, I declare that what I claim is :
:-
1. As an improved manufacture, a shoe or boot having its outer sole, or the welt
thereof, sewed to the insole and upper with a compound thread composed in part of a
metallic wire or wires, corrugated lengthwise, all being substantially as set forth.
2. As an improved manufacture, a shoe or boot having its outer sole sewed to the
welt with a compound thread, composed in part of a metallic wire or wires corrugated
lengthwise all being substantially as set forth.
3. The improved manufacture of waxed sewing thread, substantially as described,
composed of one or more corrugated metallic wires, and one or more strands of flax,
or a fibrous, vegetable or animal material intertwisted, and a covering of shoe-maker's
wax applied thereto, all being for use as set forth.
4. A sewing thread composed of one or more corrugated metallic wires, and one or
more strands of flax, or a fibrous, vegetable or animal material, intertwisted together-
all essentially as set forth.
