PROVISIONAL SPECIFICATION left by William Henry Child at the Office
of the Commissioners of Patents, with his Petition, on the 17th October
1854.
I, WILLIAM HENRY CHILD, of 21, Providence Row, Finsbury, in the City of
London, Brush Manuf, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN THE MANUFACTURE AND CONSTRUCTION OF BRUSHES"
to be as follows, that is to say :-
My first improvement consists of certain improvements in the arrangement
and disposition of the hair; secondly, the order and manner in which the hair
is arranged, inserted, and fixed in the hair frame; and, thirdly, certain con-
venient arrangements for altering, repairing, & cleaning the said brushes, and
in constructing the handles thereof.
My first improvement in the arrangement and disposition of the hair may
be generally described as being the employment of hair of various degrees of
strength or substance in one and the same brush; the object of this being
that the coarser hair may penetrate to the skin, while the softer and finer hair
removes the dandrifl' from the surface of the hair, seperated from the skin by
the stronger or coarser bristles. In respect to this part of my Invention, I
claim the employment of hair of various degrees of strength or fineness when
used in the same brush.
My second improvement being as follows:-I select bunches of the finer

page_text: description of hair, which I insert in a row of holes, the said line being either
a straight or right line, or a curved line; and I either employ one such line
or two or more parallel lines of fine hair; I then insert a similar disposition
or arrangement of strong or coarse hair. I sometimes arrange indiscriminately
bunches of fine or weak or strong and coarse hair, without order or arrange-
ment. Further, I-prefer-to-make the coarse hair bunches longer-by one quarter
of an inch or more than the fine hair, in order that the coarse hair should
penetrate better and clean the skin; the fine hair, being shorter, removes the
dandriff. In respect to the second part of my Invention, I claim arranging the
hair in bunches, variously coarse and fine, either in lines straight or curved, or
otherwise, or making one set of bunches one quarter of an inch longer-than the
other. I do not, in the above or following arrangements, confine myself to any
of the known materials with which brushes are made.
.
My third improvement may be described as follows:-I seperate the handle,
frame, or back of the brush in two or more loose pieces, so connected that one
or more of such pieces may be readily seperated one from the other; I unite
them by dovetails, screws, clasps, or other suitable means, which enables me to
clean, alter, or repair, or substitute brushes in one handle of various characters,
hard or soft. I finally construct brushes intended to be used with fluid or semi-
fluid; the said fluid being emitted or driven out through the centre or other
suitable part of the brush when in use. I finally make carpet brooms of the
usual materials, by binding it around the wooden block by leather bands,
which requires only short material.
