Complete Specification Left, 21st July, 1891-Accepted, 23rd Oct., 1891
PROVISIONAL SPECIFICATION.
A New Product Possessing the same, or nearly the same, Properties
as Spirits of Turpentine.
I, THOMAS DRAKE, of New Street, Huddersfield, in the County of York,
Solicitor, do hereby declare the nature of this invention to be as follows :-
The object of my invention is to obtain a product possessing the same or nearly
the same properties as spirits of turpentine extracted from pine wood, and this I
effect by converting petroleum spirits (benzoline), shale naptha (used for naptha
lamps) and other similar bydrocarbons, into spirits of turpentine.
According to my invention, I place any of the above named spirits into a suitable
vessel, and force therethrough one or more streams of atmospheric air, such air
having previously been dried in oxide of calcium, after which I force chlorine gas
through the said spirit, until the specific gravity thereof rises to '900 or 950,
according to the discretion and judgment of the chemist; and in order to neutralize
the acid in the spirit, I use a watery solution of commercial carbonate of soda,
which is afterwards separated from the spirit by well known chemical processes. 1
then distil the spirit with steam, after which the water is again separated, and the
spirit treated with chloride of calcium, and finally filtered through animal charcoal,
yielding a product having practically the same properties as spirits of turpen-
tine extracted from pine wood, and which may be used for the same or like
purposes.
Dated this 22nd day of October 1890.

COMPLETE SPECIFICATION.
A New Product Possessing the same, or nearly the same, Properties
as Spirits of Turpentine.
I THOMAS DRAKE, of New Street, Huddersfield, in the County of York,
Solicitor, 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 :-
The object of my invention is to obtain a new product possessing the same or
nearly the same properties as spirits of turpentine extracted from pine wood, and
this I effect by converting petroleum spirits (benzoline), or shale naptha (used for
naptha lamps) or other similar hydrocarbons into turpentine.
According to my invention I place any of the above named spirits into a suitable
vessel and force therethrough one or more streams of atmospheric air, such air
having preferably been dried in oxide of calcium, or in place thereof, 40 per cent. is
distilled off the spirit so as to increase its specific gravity, after which I force
chlorine gas through the said spirit, until the specific gravity thereof rises to .900
or 1.050, according to the purpose for which it is required and discretion and
judgment of the chemist; and in order to remove and neutralize the acid in the
spirit, which is formed during the action I first blow air through, and then use a
solution of carbonate of soda, or any suitable alkali or alkaline earth, which is
afterwards separated from the spirit by any well known chemical process or pro-
cesses, thereby yielding a product having practically the same properties as
spirits of turpentine extracted from pine wood, and which may be used for the
same or like purposes.

page_text: 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 :-
The treatment of petroleum spirits, shale naptha and other like spirits in the
imanner or by the process herein described, whereby such spirits are converted into
a new turpentine spirit or body.
