Improvements in or relating to Soap Tablets.
I, GEORGE H. EVANS, a subject of Great Britain, residing at Oroville, in the
County of Butte, State of California, United States of America, Mining 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 fol-
lowing statement:-
The object of the invention is to provide what I shall term a combination cake
of soap, one part being formed of what is known as "sand soap" and the other
portion of pure or ordinary toilet soap in order that the combined cake of soap
may serve a double purpose; the rough or sand portion being used to remove
grease, stains or dirt from the hands, while the pure or toilet soap portion is
utilized for use in washing the face.
In machine shops or such places where mechanics or workmen generally are
employed it is usual to place in the wash room two kinds of soap, that is a piece
of sand soap and a piece of ordinary toilet soap; the former being used by the
workmen to remove the grease, stains or dirt from the hands while the latter
is used for washing the face the sand soap not being desirable for use in con-
nection with the washing of the face. As the cakes of soap are separate one or
the other becomes lost and difficulty is then experienced by the workmen in
cleaning their hands or face-owing to which cake of soap is lost or misplaced.
Referring to the drawings forming a part of this application--
Figure 1 is a perspective view of the cake of soap;
Figure 2 is a vertical sectional view of Figure 1; and
Figure 3 is a detail view of the sand or pumice stone layer of the cake of soap.
Section A of the cake is composed of sand soap, pumice stone or other suitable
material capable of removing grease or stains; to which section is secured the
section A composed of ordinary toilet or washing soap; which section constitutes
a backing for the section A.
The section A is formed with a dove-tail tongue a which when the section A¹
is pressed or molded fits into the under face of the backing or section A. In
this manner the two sections are united or interlocked and held firmly together;
for, when the section A is hardened, the dove-tail tongue a may be said to fit
within a dove-tail groove a¹ in the under face of the section A¹. However, if
so desired, a dove-tail groove may be formed in the inner face of the section A
and the section A' united thereto by fitting within the said dove-tail groove.
In this case the tongue would be a part of the ordinary toilet soap instead of the
section A.
In carrying out my invention I first form in a mold or otherwise a cake of
suitable size and shape of sand soap or pumice stone, etc., which is made either
with a dove-tail tongue or groove on its inner face. This cake, or what I term
section, has united thereto the section A¹ of ordinary toilet soap, which is poured
into a mould, while in a liquid condition, onto the section A. The soap being in
a liquid condition entirely surrounds the dove-tail tongue or flows into the dove-
tail groove of the section A', as the case may be, so that when it sets or hardens

page_text: the two sections will be perfectly interlocked. If necessary, pressure may be
utilized to firmly unite the sections. After the section A has become cooled
or hardened the cake is removed from within the mold and is in condition to be
placed upon the market.
One section being interlocked with the other there is no danger of the same
becoming separated by use or rough handling,-which soap of this character is
naturally subject to.
While I prefer to unite the sections of soap as above described, it is obvious
that the tongue may be dispensed with and the ordinary toilet soap be united to the
sand soap by being run thereon while in a liquid condition so as to adhere thereto
when cooled, or pressure may be employed, if necessary, to unite the two sections.
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:
1. As a new article of manufacture a cake of sand soap or pumice stone having
a backing of ordinary toilet soap firmly united thereto.
2. As a new article of manufacture a cake of soap composed of a section of
sand soap or pumice stone and a section of ordinary toilet soap the sections being
interlocked one with the other.
3. A cake of soap comprising two sections, one section being of sand soap
or pumice stone and the other of ordinary soap the two sections being interlocked
or united by a dove-tail tongue of one fitting within a dove-tail groove of the
opposite section.
In testimony whereof I have hereunto affixed my signature; in the presence
of witnesses, this thirtieth day of June, 1897, at Oroville, in the County of
Butte. State of California.
In the Presence of
EDMUND HARVEY.
