COMPLETE DE MULTIUATION.
An Improved Inner Sole for. Boots and Shoes.
I, JOHN HENDRIE, 31, Byford Street, Edgehill, Liverpool, Cabinet Maker, 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 consists in forming an insole suitable to fill up inequalities of
surface in the inside of boots and also able to receive an impression of the under-
side or sole of the foot so that the weight of the body, will be more evenly dis-
tributed, over the surface of the said sole, and thereby the formation of corns,
or bunions be prevented or when they exist will afford a means of relieving them
from pressure.
This inner sole, is made up of two outer coverings, which may be of flannel, felt
or other suitable material. These two coverings are stitched round the edges,
leaving a slit or opening, in the instep, on the inner side of the foot, and they
can be lined with suitable paper or other substance having lappet pieces project-
ing, one of which is gummed to a corresponding lappet, on the top covering, the
other one is doubled over, and gummed to the underside of the lower covering.
I thus form a felt sack, or pouch, with lappet attached, but a seamless pouch may
be used instead if preferred.
I place in this pouch or bag a suitable quantity of a yielding composition made
by preference of the following substances and in the proportions hereafter given,
or nearly so, namely:
8 parts rice or rice flour, (by weight).

glue.
Stockholm tar.
pine or cork sawdust or a mixture of both.
acetic acid.
methylated spirit.
water.
The sawdust must be of fine grain stoved or kilned and ground up into fine
particles
If whole rice is used it must be first softened and I effect this by putting the
rice and glue into water, and allow them to stand for ten or twelve hours; the
mixture is then put in a steam bath, and boiled from 3 to 4 hours, more water
being added if required; the tar, acid, and spirit is then put in, and the whole
is again boiled for an hour or until the mass becomes of the consistency of strong
paste; the sawdust is then added, and thoroughly mixed.
I propose to pack the mixture, in round porcelain receptacles, with a division
across the centre, so that it will contain the necessary quantity, on each side to.
fill each sole; according to the sizes of soles required.
I will now describe the invention with reference to the accompanying drawings
in which:

I will now describe the invention with reference to the accompanying drawings
in which:-

page_text: Fig. 2 shows the under side of the pouch, the inner lines representing the line
of stitching. The two covers are stitched together, and then turned inside out.
Fig. 3 shows the upper side of the pouch, with lappet piece attached.
Fig. 4 shows the underside of the sole, when filled, and the lappet gummed
down.
Fig. 5. is a sectional elevation of the porcelain pot.
Fig. 6 is a plan of the lid.
Fig. 7 is a section of the same showing the bevelled edge which allows for a
layer of cement to seal it up.
Fig. 8 is a plan of inside of pot with the cover off.
The mode of filling the pouch with the mixture is as follows:-
f
With the point of a table knife, or a thin piece of chip take from one of the
divisions of the pot a third of the mixture, and put it towards the heel of the sole,
put the remainder well to the fore part; moisten the lappet, applying a little
heat, and press it firmly down. Then take up the sole and equalize the mixture,
by pressing it between the fingers and thumbs, working it well to the edges. Then
lay it on a table, or any flat surface, and with a flat piece of wood, or smoothing
iron, apply a little pressure, so as to make it perfectly flat, insert the sole in the
boot, which must be well loosened down, to give the greatest possible space and
should be full large or easy to allow the necessary space for the sole. Then insert
the foot in the boot, without disturbing the surface of the sole, and apply a slight
pressure, springing the fore-part of the foot. Take the boot carefully off; and if
there is a very prominent corn, rub a piece of chalk, on the stocking over the
place, put the boot on again, and slightly press on that portion of the foot where
the corn is located; take the boot off, look for the chalk imprint, and press the
mid finger directly on it, so as to leave a little hollow in the sole. Then put the
boots aside for ten hours, while the sole commences to set. Next, put the boots
on and walk in them for a minute or two, then allow them to dry for. a day, and
they will be ready for use.
In a few days this mixture becomes hard and firm like a cement.
Having now particularly and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In an insole for boots or shoes the employment of a pouch or bag of suitable
shape and size containing a yielding or plastic composition, which receives an
impression of the sole of the foot, and ultimately hardens, as herein described
and set forth.
2. A special composition for taking an imprint of the sole of the foot, to be used
inside a suitable bag or pouch as an insole for boots and shoes, and a pot for con-
taining the same, as herein described and set forth.
