Improved Soap for Carpets.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 322 High Holborn, in the County of Middlesex,
6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in the
County of Lancaster, and Lower Temple Street, Birmingham, in the County
of Warwick, Civil Engineer, 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 the present invention consists in the preparation of a soap by the
use of which the dirtiest carpet can be cleansed and a new and bright appearance
given to it by simply soaping and washing it. The advantage of this invention
consists not only in the important saving of time and labour, but also in the fact
that by the use of this soap the article to be cleansed is in no way attacked or
injured. So satisfactory results could not be attained by the use of soaps hitherto
known nor by the well known mechanical carpet cleansing, works. The soaps
hitherto known do not contain the requisite ingredients for the entire removal of
the dirt and at the same time for the freshening of the material, whilst the
mechanical apparatuses frequently injure the fabric especially in the case of tender
carpets. Moreover, it is usual to give the carpets a further washing with hot
water, or even to boil them with certain ingredients. Yet, nevertheless even in
the case in which the dirt has been effectively removed the colours are very liable
to be injured and destroyed. This method of cleansing carpets is therefore not to
be recommended.
The soap which forms the subject of the present invention obviates the above
named drawbacks and requires very simple manipulation. Its preparation is
similar to that usually employed for making the so called bar or block soap.
The ingredients for the cleansing and brightening of the carpet are mixed in the
manner hereinafter set forth. These ingredients are divided into two parts
1) Those intended for the dissolving and removing of the dirt.
2) Those which are devised to brighten the colours and restore them to
their original condition as long as the same have not been destroyed by
mechanical or chemical action.
For the preparation of the soap in question sixty parts of hot saturated solution
of common soap are mixed with twelve parts of sal ammoniac and four parts of
turpentine. After diligent stirring sixteen parts of fresh and pure ox-gall are
added. There are then added with continued stirring eight parts of acetic ether,
ten parts sugar, and three parts good honey. In order to give the preparation an
agreeable scent there is further added four parts of an ethereal oil. After the
mixture has been stirred for about twenty minutes to effect complete combination
it is run off and formed into bars or blocks.
The application of this soap is preferably as follows:-
A quantity of the soap is first dissolved in lukewarm water so that a good strong
lye without foam is formed, with this the carpet is treated in whole or in part

page_text: according to its size and is then lightly or heavily rubbed with brushes or
scrubbers. The article under treatment can remain in its place even during the
drying, nevertheless in the case of large carpets it is advisable to hang them up.
A few of the advantages obtainable by means of this soap are as follows:-
1. By the use thereof dirt and greasy marks are removed.
2. The nap of felted carpets is again restored.
-:
3. The original colours are again restored so far as they have not been destroyed
by chemical or mechanical means.
4. Printed carpets may be washed with this soap without causing the colours to
be discharged or run. together.
15. The preparation destroys any settlement of moth.
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 :-
