page_text: We CHARLES PIERCE MERRIAM, of 124 High Street, Homerton, in the County
of Middlesex, Manufacturer and JAMES ROBINS, of 61 Oriel Road, Homerton
aforesaid, Comb Maker 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:-
This invention has reference to the manufacture of brushes whose backs (or
backs and handles combined) have a wooden or other core or body covered with
or enclosed within xylonite, celluloid or pyroxylin compound Hitherto in the
manufacture of brush backs of this description the xylonite covering has been
formed of an upper and a lower shell between which when in a softened state the
core has been placed the two shells being then united at their edges by suitable
pressure. The joint of the two shells has been along the middle of the periphery
or rim of the brush back thus inade, and has frequently been found to open when
the brush has been some time in use.
Now this invention consists in manufacturing brush backs or backs and handles
combined as follows:-We take a core of wood or other suitable material of
somewhat smaller dimensions than that of the back (or back and handle) to be
manufactured and we fix around its periphery a rim or collar of xylonite or
pyroxylin compound; this xylonite rim or collar is applied by means of pressure
and when in a soft state as will be well understood. Upon one face of the core
and collar, viz: that which is to be the inner face of the brush, we then affix a
thin sheet or veneer of xylonite. We next form in the back thus partly made the
usual holes for the tufts of bristles or hairs and then draw these in any ordinary
manner. And we finally affix to the other face, viz-to that which is to be the
outer face of the brush a thin sheet or veneer of xylonite. Thus instead of there
being a joint in the xylonite pieces around the middle of the edge or periphery of
the brush back, as in the old mode of making brush backs of this description,
which joint is liable to open, there is a joint around each edge and these joints
are much more permanent.
The annexed drawings will serve to illustrate our invention. Figure 1 is a face
view of a core a of wood or other material with a rim or collar 6 of xylonite
affixed around its periphery as above described. Figure 2 is a transverse section
of the back after a thin sheet or veneer of xylonite-marked c in the figure-has

page_text: been affixed to one face of the core a and collar b. Figure 3 is a similar section of
the back after the tufts have been drawn and a thin sheet or veneer of xylonite―
marked d―has been affixed to the other face. Figure 4 is a side view. The joints
of the xylonite pieces are around the upper and lower edges e, e.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
Manufacturing brush backs or combined backs and handles by fixing around the
periphery of a core or body of wood or other material a rim or collar of xylonite
or pyroxylin compound and fixing two thin sheets or veneers of xylonite or 1
pyroxylin compound to the two faces respectively, substantially as set forth.
