Improvements in or relating to the Manufacture of Boots, Shoes,
and the like.
We JOHN BRYAN & ALFRED HENRY BRYAN of Nelson Works, Kettering
in the County of Northampton, Boot & Shoe Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the manufacture of boots, shoes and the like and has
particular reference to the connecting of the welt to the insole and upper.
The invention is designed with a view of increasing the flexibility of a boot or
shoe without interfering with its solidity or durability.
According to our invention the welt, instead of being connected to the upper and
insole by sewing, is attached by preferably screwed wire, at intervals round the
boot or shoe.
The welt may be first temporarily attached to the upper and insole by tacks and
then the whole fastened together by screwed wire or its equivalent.
The invention may be most readily carried into effect by the use of what is known
in the trade as a "standard-screw machine" although we reserve to ourselves the
right to use any other mechanical process for inserting the screwed wire or thread.
The welts may, if desired, be moulded to the shape of the boot or shoe before
being screwed thereon.

COMPLETE SPECIFICATION.
Improvements in or relating to the Manufacture of Boots, Shoes,
and the like.
We, JOHN BRYAN and ALFRED HENRY BRYAN of Nelson Works, Kettering
in the County of Northampton, Boot and Shoe Manufacturers, 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 the manufacture of boots, shoes and the like and has
particular reference to the connecting of the welt to the insole and upper.
The invention is designed with a view of increasing the flexibility of a boot or
shoe without interfering with its solidity or durability.
According to our invention the welt, instead of being connected to the upper and
insole by sewing, is attached by preferably screwed wire, at intervals round the
boot or shoe.
The welt may be first temporarily attached to the upper and insole by tacks and
then the whole fastened together by screwed wire or its equivalent.
The invention may be most readily carried into effect by the use of what is
known in the trade as a "standard screw machine" although we reserve to ourselves
the right to use any other mechanical process for inserting the screwed wire or
thread.
The welt may, if desired, be moulded to the shape of the boot or shoe before
being screwed thereon.
Referring to the accompanying drawing
Figure is a plan of the underside of an upper and insole shewing the welt
attached thereto according to this invention.

page_text: Figure 2 is a central longitudinal section thereof and
Figure 3 a transverse section, and Figure 4 a view of one of the wire studs, on
an enlarged scale.
A. represents the insole of a boot or shoc, and B the upper whose marginal edge
is turned under thereon and fixed in position by tacks E or other means.
The boot may either be lasted by hand in the well known manner or by any of
the lasting machines used for that purpose.
C represents the welt which is secured to the upper and insole by a series of
short screwed wires D (shown separately in Figure 4) inserted at intervals round
the welt and which may be either in one row as shown in Figure 1 or two or more
rows as desired.
In the event of more than one row being used the screwed wires D are placed
opposite the intervals in the adjacent row or rows.
In Figures 2 and 3 the wire D is shown most clearly as passing through the
insole A, upper B and welt C, the "Standard screw machine" breaking off the
wire close to the leather, i.e. the insole on one side and welt on the other.
A sock may be used inside the boot or shoe to avoid any possible rough or jagged
point of the wire therein hurting the foot of the wearer but as a rule this will be
found unnecessary.
The wire D. being screwed it is obvious that it cannot wear loose or drop out
with the ordinary motions of the foot when in action and being formed of a non-
corrodible material it follows that its durability is far greater than the wax
threading usually employed in sewing the welt to the upper, while the flexibility is
at the same time increased.
In connecting the welt in the manner hereinbefore described it is advisable to usc
wire with the deepest cut screw thread that the "Standard screw machine" will
employ as suitable for the purpose named, as it will become embedded more firmly
in the leather than a shallow cut screw thread and thereby-be more secure and
durable.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A boot, shoe or the like in which the welt is secured thereto by screwed wire
substantially in the manner described and illustrated in the accompanying drawing.
