COMPLETE SPECIFICATION.
An Improvement in what is commonly called Dry Soap or
Soap-powder.
I WILLIAM HENRY HORTON of 11 Wellington Terrace, Shrewsbury Street,
Old Trafford, Manchester in the County of Lancaster, Chemical Manufacturer
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:-
My invention relates to what is commonly called dry soap or soap-powder and
consists in an improvement by which I am enabled to increase the efficiency of
such dry soap or soap-powder in the washing of clothes and other articles or
objects and for many of the other purposes for which dry soap or soap-powder is
used, and render it much more easy and convenient than it has hitherto been to
disinfect clothes and other articles or objects while they are being washed.
According to my invention, I cause a suitable proportion of any one or more or
all of certain disinfectants hereinafter mentioned to be incorporated or mixed with
the materials or substances of which dry soap or soap-powder is formed so that
such disinfectant or disinfectants shall be contained in such dry soap or soap-
powder when its manufacture is completed. The disinfectants, any one or more or
all of which may be employed according to my invention are carbolic acid, cresylic
acid, and the other analogous substances or materials which have disinfecting
properties. The disinfectant or disinfectants to be added to dry soap or soap-
powder in the manufacture of such dry soap or soap-powder in accordance with my
invention are diluted or mixed with a suitable quantity of water and are added to
the materials or substances of which the dry soap or soap-powder is to be formed
during the period in the manufacture of the dry soap or soap-powder in which such
materials or substances form a semi-liquid mass. The disinfectant or disinfectants
added to the said materials or substances is or are thoroughly incorporated or mixed
therewith by stirring or in any other suitable manner, and afterwards the manu-
facture of the said materials or substances into dry soap or soap-powder is proceeded
with in the manner hitherto customary in the manufacture of dry soap or soap-
powder. When carbolic acid is used in accordance with my invention the quantity
of carbolic acid to be used may be so much carbolic acid diluted to a suitable
strength as will contain the equivalent of a quantity of crystalline carbolic acid
equal to from two to ten per cent., and preferably about five per cent., of the weight
of the semi-liquid mass of the materials or substances to which it is to be added in
the manner above described. When any other disinfectant or disinfectants of those
above mentioned is or are employed either instead of or in combination or mixture
with carbolic acid the quantity of the disinfectant or disinfectants used must be
such as will make the total quantity of disinfectant or disinfectants which is or
are employed approximately equivalent to that stated above in reference to
carbolic acid.
Dry soap or soap-powder manufactured according to my invention may have
any suitable bluing or colouring substance or material added to or incorporated
with it in the process of manufacture. Any suitable essence or oil having scenting
properties or any other suitable scenting material may be added to dry soap or
soap-powder manufactured according to this invention, during the process of the
manufacture of such dry soap or soap-powder.
Dry soap or soap-powder manufactured according to my invention having
disinfecting properties is more efficient in the washing of clothes and other
articles and objects than the dry soap or soap-powder hitherto manufactured and

page_text: renders it much more easy and convenient than it has hitherto been to disinfect
clothes and other articles and objects in the washing of such clothes and other
articles or objects.
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 :-
In dry soap or soap-powder, carbolic acid or any other of the disinfectants
hereinbefore mentioned or any two or more or all of such disinfectants mixed or
incorporated with such dry soap or soap-powder in its manufacture substantially as
and for the purpose hereinbefore described.
Dated this First day of May 1894.
