NOW KNOW YE, that I, the said Thomas Rainforth Tebbutt, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement (that is to say):-
"
My improvements in the manufacture of soap, soda, washing powders,
crystals, or paste consists in the novel employment and use of such oils
or spirituous extracts as "petroleum," "rock oil," "parifine," "camphine,"
naptha," and other such similar oils and spirits as are procured from mineral
substances (or naptha procured from wood) and possessing detergent pro-
perties. The oils or spirits are to be mixed and incorporated with the washing
material in any required proportions to increase the cleansing or detergent
powers thereof. I would remark in the manufacture of soap, for instance,
that the employinent or addition of the aforesaid oils or spirituous extracts

page_text: requires no alteration in the method of manufacturing the saponaceous body
to which it added, but is to be mixed therewith when the soap is finished,
either in the pan or frame, and is applicable to all soaps wherein too great an
amount of resin does not exist. The quantity of oil or spirituous extracts is to
be varied according to the amount of detergent property required; for instance,
for an ordinary household and light cleansing purposes, take of manufactured
soap (called white curd) one ton, and add thereto from thirty to sixty pounds
of oil or spirituous extract according to requirement; but I do not wish to
confine myself to. the precise proportions.
Having now described the nature of the said Invention, together with the.
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim the novel employment and use of any oil or spirituous
extract of similar nature to the oils or spirituouse xtracts, before nambed, in
the manufacture of soap, soda, or washing powders, as herein-before described
and set forth.
In witness whereof, "I, the said Thomas Rainforth Tebbutt, have here-
unto set my hand and seal, this Twentieth day of December, in the
year of our Lord One thousand eight hundred and sixty-two.
THOMAS RAINFORTH TEBBUTT. (L.S.)
