COMPLETE SPECIFICATION.
An Improved "Blinder" for Use in the Manufacture of Boots and
Shoes.
I, WILLIAM FRANCIS COWLE, of 156 York Road, New Cat, Bedminster, in the
city and county of Bristol, boot and shoe manufacturer, 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 pins, pegs or nails used for holding together the outer
and in soles or the outer, mid, and in soles of a boot or shoe prior to the operation
of sewing the said soles together in a boot and shoe sewing machine.
Such pins,
pegs or nails are technically termed "blinders."
Blinders, as hitherto used, have nothing to prevent them from being forced, as the
outer sole wears, above the insole further into the boot or shoe and so causing
discomfort or injury to the foot of the wearer.
Now this invention consists in providing a blinder with a shoulder at any desired
suitable point between the ends thereof.
The blinders are driven into the insole until arrested by contact of the shoulders
with the outer face of the said insole.
That part of the shank of each blinder which extends outwards from the shoulder
is then cut with the proper instrument to the length required and the outer sole is
placed upon the blinders and held thereby. The soles are then sewn together in a
sewing machine, as is well understood. A midsole may intervene between the insole
and the outsole, in which case the shoulders of the blinders still remain next to the
insole and the outwardly extending shanks are passed through the midsole to receive
the outsole.
Fig. 1 in the accompanying drawing represents a side elevation and Fig. 2 a
plan of one form of my improved blinder for use in the manufacture of boots and
shoes.
At any desired point between the extremities of the shank a is a shoulder b
which, although represented in the drawing as circular, may be of oval, square, oblong
or other suitable shape.
The position of the shoulder relatively to the extremities of the shank may vary.
When, in driving the blinder into the insole, the shoulder b comes into contact
with the outer face of the said sole, further penetration of the blinder is prevented.
That part of the shank upon which the outer solo is received, or upon which the mid
and outer soles are received, is then cut to the desired length and the outer sole, or
midsole and outersole, placed on the projecting shanks and forced down thereon in the
usnal manner.
The soles are then sewn together as usual.
As the whole sole diminishes in thickness with wear, the blinders are prevented.
by the shoulders from being forced into the boot or shoe further than the point to
which they were originally driven.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
"
In a blinder" for use in the manufacture of boots and shoes, the provision of a
suitably shaped shoulder or stop situated at any desired point between the extremities
of the shank. substantially as hereinbefore described and for the purpose specified.
