IMPROVEMENTS IN THE TREATMENT OF LEATHER
Year: 1884

page_text: I, JAMES PATERSON, of Glasgow, in the County of Lanark, North Britain,.
Wholesale Boot and Shoe Manufacturer and Leather Merchant do hereby declare
the nature of the said invention for "IMPROVEMENTS IN THE TREATMENT OF
LEATHER" to be as follows:-
This Invention, which, relates to improvements in the treatment of leather, has
for its object to overcome or considerably diminish the tendency of leather to
stretch when strained, as for example when it is used for driving belts, hose pipes,
hydraulic leathers, harness, saddlery, and other manufactures wherein such leather
is subjected to the influence of tension.
The leather treated according to this Invention may be in the state in which it
leaves the tanyard or it may be in the oily or greasy condition in which it leaves
the Currier's. The treatment constituting the Invention being applicable to leather
in either of the aforesaid conditions.
The invention consists in melting together unwrought wood resin and gumthus
which is otherwise known as Frankincense. To give an example of practising the
invention there is melted together 28 lbs. weight of resin and 70 lbs. of gumthus,
and, when heated, these substances are stirred together until they are thoroughly
commingled. These melted and commingled substances are then removed from the
melting vessel and are placed in any other suitable vessel, wherein is mixed with
them about one gallon of boiled or Linseed oil, and there is also added about
two lbs. weight of the India Rubber Solution of Commerce, which is previously
diluted in a quantity of Petroleum Benzoline or Bi-sulphide of carbon sufficient
to render the same liquid.
When all the foregoing substances are thoroughly commingled, there is added
thereto à further quantity of Petroleum Benzoline, sufficient to prevent the mixture
of substances from setting into a hard mass. It is preferred to add the Petroleum
Benzoline in quantity sufficient to reduce the mixture to about the degree of
fluidity of molasses at the ordinary temperature of the atmosphere, and there is
added to it a further quantity of Petroleum Benzoline to render the mixture
sufficiently liquid to penetrate the pores of the leather.
In treating leather by the mixture or compound hereinbefore described, the
leather is immersed in a tank containing the said mixture or compound and it is
Kept immersed therein until the pores are fully charged with the said compound
1

page_text: when it is taken out and washed in a bath of Petroleum Benzoline, after which the
pieces of leather so treated are spread out on racks or their equivalent to dry.
It is to be understood that the foregoing example which is given of the
proportions of the several substances is one wherein the invention may be
advantageously used more especially for leather in a state of tension, but the said
proportions may be varied.

I, JAMES PATERSON, of Glasgow, in the County of Lanark, North Britain,
Wholesale Boot and Shoe Manufacturer and Leather Merchant do hereby declare
the nature of my said invention for IMPROVEMENTS IN THE TREATMENT OF
LEATHER and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This Invention, which relates to improvements in the treatment of leather, has
for its object to overcome or considerably diminish the tendency of leather to
stretch when strained, as for example when it is used for driving belts, hose pipes,
hydraulic leather, harness, saddlery and other manufactures wherein such leather
is subjected to the influence of tension.
The leather treated according to this Invention may be in the state in which it
leaves the tanyard, or it may be in the oily or greasy condition in which it leaves
the Currier's. The treatment constituting the Invention being applicable to leather
in either of the aforesaid conditions.
The Invention consists in melting together unwrought wood resin and gumthus
which is otherwise known as Frankincense. To give an example of practising the
Invention there is melted together 28 lbs weight of resin and 70 lbs of gumthus,
and, when heated, these substances are stirred together until they are thoroughly
commingled. These melted and commingled substances are then removed from the
melting vessel and are placed in any other suitable vessel, wherein is mixed with
them about one gallon of boiled or Linseed Oil, and there is also added about two
pounds weight of the India Rubber Solution of Commerce, which is proviously
diluted in a quantity of Petroleum Benzoline or Bi-sulphide of carbon sufficient
to render the same liquid.
When all the foregoing substances are thoroughly commingled, there is added
thereto a further quantity of Petroleum Benzoline, sufficient to prevent the mixture
of substances from setting into a hard mass.-It is preferred to add the Petroleum
Benzoline in quantity sufficient to reduce the mixture to about the degree of
fluidity of molasses at the ordinary temperature of the atmosphere, and there is
added to it a further quantity of Petroleum Benzoline to render the mixture
sufficiently liquid to penetrate the pores of the leather.
In treating leather by the mixture or compound hereinbefore described, the
leather is immersed in a tank containing the said mixture or compound and it is
NO

page_text: kept immersed therein until the pores are fully charged with the said compound
when it is taken out and washed in a bath of Petroleum Bonzoline, after which the
pieces of leather so treated are spread out on racks or their equivalent to dry.
It is to be understood that the foregoing example which is given of the
proportions of the several substances is one wherein the Invention may be
advantageously used more especially for leather in a state of tension, but the said
proportions may be varied.
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:-
The treatment of leather by the substances herein before mentioned used in the
manner or process hereinbefore described whereby leather so treated is better
adapted for resisting the influence of tension.
