I, GREGORY SAKHEIM, of 40, Queen Street, in the City and County of London,
Skin Merchant, do hereby declare the nature of this invention to be as follows:
This invention relates to the manufacture of boots and shoes preferably from one
piece of leather more or less waterproof.
The object of this invention is to manipulate the leather so as to render it
sufficiently supple to enable it to be formed with facility on any ordinary last or
block and thereby to produce a properly shaped boot or shoe having when desired:
a waterproof character.
In manufacturing boots and shoes according to this invention I proceed as
follows; I first cut the leather blank to the desired shape, and I then submit
those parts of the blank which are to be shaped on the last to a steam jet or jets
until they are sufficiently supple for the purpose, when I place the blank on the
last and shape it in the ordinary way. The boot or shoe after shaping is left on
the last and placed in a hot room or other place where the temperature is regulated
according to the thickness or softness of the leather used until thoroughly dry.
For thin leather about three hours is sufficient for drying but for thicker leathers
the time should be extended.
As a modification instead of steaming the blank I soak it in a mixture consisting.
of whale oil, palm oil and sweet oil in about the following proportions:-
A mixture of this kind not only renders the leather soft and pliable so as to
adapt it for shaping on a last but also renders it waterproof.
I prefer to use the mixture of oils in a hot state and I soak the leather therein
for a convenient time according to its thickness. If the leather be thin I find that
a soaking of three hours is sufficient but for thicker leathers a longer time
should be allowed for the soaking.
In some cases I line the shoe or boot, the process being then as follows:-First'
the lining blank is put on the last and shaped thereon, then the boot or shoe blank
is secured thereto by paste and stitching or otherwise and is shaped or formed on
the last and finished and closed in the ordinary way.
Where an inside sole is required I secure this in position on the lining after the

page_text: latter has been shaped on the last, by paste or otherwise in the ordinary way,
then apply the boot or shoe blank and finish off as above described.

Improvements relating to the Manufacture of Boots and Shoes.
I, GREGORY SAKHEIM, of 40, Queen Street, in the City and County of London,
Skin Merchant, 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 and shoes preferably from
one piece of leather, that is to say, boots and shoes of the kind in which the sole
and the upper, or the sole and a portion of the upper, consist of one piece of 1
leather.
The object of this invention is to manipulate the leather so as to render it
sufficiently supple to enable it to be formed with facility on any ordinary last or
block and thereby to produce a properly shaped boot or shoe having when desired
a waterproof character.
In manufacturing boots and shoes according to this invention I proceed as
follows; I first cut the leather blank to the desired shape, and I then submit
those parts of the blank which are to be shaped on the last to a steam jet or jets
until they are sufficiently supple for the purpose, when I place the blank on the
last and shape it in the ordinary way. The boot or shoe after shaping is left on
the last and placed in a hot room or other place where the temperature is
regulated according to the thickness or softness of the leather used until thoroughly
dry. For thin leather about three hours is sufficient for drying but for thicker
leathers the time should be extended.

As a modification instead of steaming the blank I soak it in a mixture of whale 3
oil, palm oil and sweet oil in about the following proportions.

A mixture of this kind not only renders the leather soft and pliable so as to 3
adapt it for shaping on a last but also renders it waterproof.
I prefer to use the mixture of oils in a hot state and I soak the leather therein
for a convenient time according to its thickness. If the leather be thin I find that
a soaking of three hours is sufficient but for thicker leathers a longer time should
be allowed for the soaking.
In some cases I line the shoe or boot, the process being then as follows;-First
the lining blank is put on the last and shaped thereon, then the boot or shoe blank
is secured thereto by paste and stitching or otherwise and is shaped or formed on
the last and finished and closed in the ordinary way.

Where an inside sole is required I secure this in position on the lining after the 4
latter has been shaped on the last, by paste or otherwise in the ordinary way, and
then apply the boot or shoe blank and finish off as above described.

page_text: An outer sole and a heel may be secured to the boot or shoe in any well known
manner.
Having now particularly described 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. A boot or shoe made from a blank of leather formed so that the sole and the
upper or the sole and a portion of the upper consist of one piece, the leather blank
being steamed, then shaped on a last in the ordinary way and subsequently dried
by artificial heat, substantially as herein described and for the purpose stated.
2. A boot or shoe made from a blank of leather formed so that the sole and the
upper or the sole and a portion of the upper consist of one piece, the leather blank
being soaked in a mixture of whale oil, palm oil and sweet oil in about the pro-
portions herein stated, then shaped on a last in the ordinary way and subsequently
dried by artificial heat, substantially as herein described and for the purpose
stated.
3. The process substantially as herein described for treating a leather boot or
shoe blank of the kind indicated consisting in soaking it for a suitable time in a
mixture of whale oil, palm oil and sweet oil in about the proportions stated and for
the specified purpose.
4. The improvements relating to the manufacture of boots and shoes sub-
stantially as herein described and for the purpose stated.
