PROVISIONAL SPECIFICATION.
Improvements in Machines for Laying or Attaching Soles to Boots
and Shoes.
I, WILLIAM HENRY DORMAN, of the Green Hall, Stafford, Engineer, do hereby
declare the nature of this invention to be as follows:-
-
The object of this invention is to improve a machine used for applying pressure
to the soles of boots and shoes by applying to it an apparatus for the purpose of
making it more durable than hitherto.
The machine operates by hydraulic pressure applied to a mould containing water
or the like which has an indiarubber bottom to bear upon the surface of the
boot sole.
My improvement consists in providing a sheet of canvas, or indiarubber and
canvas, or leather, or the like, which I arrange beneath the indiarubber bottom
of the mould so that it intervenes between the mould and the shoe sole. This
sheet may be provided with eyelets around its edge and be furnished with springs
to support it which yield to allow the sheet to conform to the boot sole when the
water pressure is applied inside the mould. Injury to the indiarubber forming the
mould bottom is thus prevented by the intervening sheet.
If preferred the sheet may have sufficient slackness in itself to allow it to
conform to the shape of the boot sole and the supporting springs may be dispensed
with.
In some cases I provide a strip of thin sheet steel, especially where nails or the
like in the shoe are likely to do injury to the sheet or mould.

Improvements in Machines for Laying or Attaching Soles to Boots
and Shoes.
I, WILLIAM HENRY DORMAN, of the Green Hall, Stafford, in the County of
Stafford, 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:-
This invention relates to improvements in machines for applying pressure to
the soles of boots and shoes of the kind wherein hydraulic pressure is applied to
a mould containing water or the like which has an india-rubber bottom to bear
upon the surface of the boot sole.
The object of the invention is to render such machines more, durable than
TD 077

page_text: hitherto and to this end I provide a sheet of canvas, or india-rubber and canvas,
or leather, or the like, which I arrange beneath the india-rubber bottom of the
mould so that it intervenes between the mould and the shoe sole. This sheet may
be provided with eyelets around it edge and be furnished with springs to support
it, which springs yield to allow the sheet to conform to the shape of the boot sole
when the water pressure is applied inside the mould. Injury to the india-rubber
forming the mould bottom is thus prevented by the intervening sheet.
If preferred the canvas or other sheet may have sufficient slackness in itself
to allow it to conform to the shape of the boot sole and the supporting springs may
be dispensed with.
To enable the invention to be fully understood I will describe it by reference
to the accompanying drawing, in which:-
Figure is a longitudinal vertical section of a mould of the kind described
in the Specification of my former Patent No. 6096 of 1899 and having the present
improvements applied thereto.
Figure 2 is a plan thereof; and
Figure 3 is a sectional elevation of a detail.
a is the mould dish which is provided with the india-rubber bottom b and the
ring c, and d is the boot.
6 is the sheet of rubber and canvas or other suitable material which is arranged
to intervene so as to form a shield between the boot or shoe sole and the bottom b
of the mould. The said sheet c is supported from the hooks f; f to which it is
secured through the medium of the springs g, g attached to it by the eyelets g', g'.
The hooks themselves are preferably secured as shewn in Figure 3, to the bolts h, h
which fasten the ring and bottom to the dish a..
C
When, in operating the machine, the boot d is dropped and swung forward the
shield lies level as shewn in Figure 3 and when the boot is swung back and
raised as shewn in Figure 1 the shield e is carried up by the boot against the
india-rubber bottom conforming to the shape of the last bottom and boot sole
and protecting the india-rubber bottom against injury from the edges or other
parts of the sole liable to cause injury.
is a spring which is fastened to the front of the shield e and to the eye j fixed
to the dish a, its object being to hold up the front end of the shield and prevent
the boot or shoe striking it on entering and leaving.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In a machine of the kind described for laying or mouluing boot and shoe
soles the combination with the mould of a shield arranged between the india-
rubber bottom of the mould and the boot or shoe sole substantially as hereinbefore
described.
2. In a machine of the kind described in Claim 1, attaching the shield to the
mould by means of springs secured to it around its edge or periphery, substantially
as herein before described
3. The improved mould for use with machines for laying or moulding boot and
shoe soles, consisting of the parts combined arranged and operating, substantially
as herein before described and illustrating in the accompanying drawing.
