page_text: We-JOHN LORD HINDE. of No. 103 Suffolk Street Birmingham in the County.of
Warwick Manufacturer and WILLIAM LORD BALLIN HINDE of No: 15 Oxford Street
Birmingham aforesaid Manufacturer do hereby declare the nature of this Invention
to be as follows:
Our improvements have reference principally to hair brushes but are also applicable
to various other kinds of brushes such for example as clothes brushes shoe brushes
and the like.
We will describe our invention in connection with the manufacture of a hair
brush.
In manufacturing a hair brush according to our invention we proceed as follows.
We take a flat disc of waterproofed strong mill board metal or other rigid material
the said disc having the outline of the body of the brush to be made. We drill or pierce
in the said disc holes in which the bristles or wires or tufts of bristles or wires are to
be fixed, the number and disposition of the said holes being determined by the size
and character of the brush to be made. After the said disc has had the holes drilled
or pierced in it we subject it to the action of a pair of dies the moveable die of which
is worked in a press and the fixed die is stationed on the bed of the said press. The
said dies have the configuration necessary to give to the disc operated upon a dome
like figure that is the disc after having been operated upon is convex on one side and
concave on the other. The bristles or wires are now fixed in the holes in the dome
shaped disc the said bristles or wires standing on the convex side of the disc and.in.
consequence of the convexity, which has been given to the said disc the said bristles
or wires take the required position that is from the middle to the marginal parts of
the said disc the bristles or wires progressively assume a more outwardly inclined
position each bristle or wire or tuft standing at right angles to that part of the dome
shaped disc to which it is attached. The disc with the attached bristles or wires is fixed
on the stock of the brush by lacing cementing or otherwise.
Although we prefer to use waterproofed mill board or sheet metal in carrying our
invention into effect yet we do not limit' ourselves thereto as any other material

page_text: capable of being readily drilled or pierced and capable of receiving and retaining the
dome shaped figure described may be employed.
We make the dome shaped disc of sufficient strength to resist any change of figure
by the pressure to which it is likely to be exposed in use.
Where however, the brush is likely to be exposed to very great pressure the space
between the under concave side of the disc and the stock may be filled with packing
material.

Improvements in the Manufacture of Hair and other Brushes.
We JOHN LORD HINDE of No. 103 Suffolk Street Birmingham in the County of
Warwick Manufacturer and WILLIAM LORD BALLIN HINDE of No. 15 Oxford Street
Birmingham aforesaid Manufacturer do hereby declare the nature of our Invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
Our improvements have reference principally to hair brushes but are also applicable
to various other kinds of brushes such for example as clothes brushes, shoe brushes
and the like.
We will describe our invention in connection with the manufacture of a hair
brush.
In manufacturing a hair brush according to our invention we proceed as follows.
We take a fat disc of waterproofed strong mill board, metal or other rigid material
the said disc having the outline of the body of the brush to be made. We drill or
pierce in the said disc holes in which the bristles or wires or tufts of bristles or wires
are to be fixed the number and disposition of the said holes being determined by the
size and character of the brush to be made. After the said disc has had the holes
drilled or pierced in it, we subject it to the action of a pair of dies the movable die of
which is worked in a press and the fixed die is stationed on the bed of the said press.
The said dies have the configuration necessary to give to the disc operated upon
a, dome like figure; that is, the disc after having been operated. upon is convex
on one side and concave on the other. The bristles or wires are now fixed in the
holes in the dome shaped disc or body the said bristles, or wires standing on the
convex side of the disc or body and in consequence of. the convexity which has been
given to the said disc the said bristles or wires take the required position that is, from

page_text: the middle to the marginal parts of the said 'dise or body the bristles or wires
progressively assume a more outwardly inclined position, each bristle or wire or
tuft standing at right angles to that part of the dome-shaped disc or body to which
it is attached. The disc or body, with the attached bristles or wires, is fixed on the
stock of the brush by lacing, cementing or otherwise.
Although we prefer to use waterproof millboard or sheet metal in carrying our
invention into effect yet we do not limit ourselves thereto as any other material
capable of being readily drilled or pierced and capable of receiving and retaining the
dome shaped figure described may be employed.
We make the dome-shaped disc or body of sufficient strength to resist any change of
figure by the pressure to which it is likely to be exposed in use.
Where however the brush is likely to be exposed to very great pressure the space
between the under concave side of the disc and the stock may be filled with
packing material.
Figure of the accompanying Drawing represents in side elevation a hair brush
made according to our invention.
Figure 2 represents in plan and edge view the flat elliptically shaped disc of water- .
proofed millboard to which the bristles or wires or tufts of bristles or wires are to be
secured.
Figure 3 represents in plan and edge view the flat disc of waterproofed millboard
after it has been pierced or drilled with holes arranged preferably so as to follow
the outline of the disc. Figure 4 represents in plan, and longitudinal section the
pierced disc Figure 3 after it has been operated upon by press tools so as to
give to the said disc a dome like figure as represented. Figure 5 represents in
plan of upper side Figure 6 in side elevation and Figure 7 in cross section
(with some of the bristles omitted) the body of the brush made by fixing the bristles
(or wires) in the holes or perforations in the dome shaped disc by wiring in the usual
manner.
In the Drawing, the plain or unperforated disc of millboard is marked a; the
perforated flat disc is marked b; the dome shaped perforated disc is marked c; the
perforations & and the bristles (or wires) e. The stock of the brush is marked f. It
will be seen that the bristles (or wires) e stand on the convex side of the dome shaped
disc or body e and in consequence of the figure of the said disc or body they take the
position upon it illustrated by a portion of a row of bristles in Figure 7 where it will
be seen that from the middle to the marginal parts of the disc or body c the bristles
(or wires) progressively assume a more outwardly inclined position, each bristle or
wire or tuft standing at right angles to that part of the dome shaped disc or body e to
which it is affixed. The dome shaped disc or body c (Figures 5 6 and 7) with the
bristles (or wires) attached to it is secured to the stock of the brush represented in
Figure 1 by the edge of the said disc being cemented in the undercut internal edge
of the said stock fas represented in Figure 1 but we do not limit ourselves to any
particular way of attaching the disc or body carrying the bristles or wires to the stock
of the brush. The space between the concave underside of the dome shaped disc or
body e and the stock may (if required) be filled with a. packing material to support
the said dome shaped disc or body against the pressure to which it may be subjected
in use and thereby preserve its figure but for ordinary purposes the use of the said
packing is unnecessary.
The press tools which we use for cutting out the flat dises and for doming the
perforated flat discs as well as the drilling or piercing tools used for perforating
the flat discs prior to doming them are of the kind commonly employed for like
operations and are used in the same way.
We do not limit ourselves to making the discs or bodies of waterproofed millboard
as sheet metal or other rigid material, such for example as vulcanite or hardened
india rubber, may be employed. Neither do we limit ourselves to the shape of the
disc constituting the body of the brush as the disc or body and the handle may be
made in one piece by the dies; nor to the disposition of and manner of securing the
bristles or wires to the disc or body of the brush.

page_text: Our improvements may be applied to brushes of various kinds in which the bristles
or wires are required to have a progressively outwardly inclined figure from the
middle to the marginal parts of the brush.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our invention
"
The improvements in the manufacture of hair and other brushes hereinbefore
described and illustrated in the accompanying Drawing that is to say, attaching the
bristles or wires or tufts of bristles or wires to a perforated dome shaped disc or body
of waterproofed strong millboard, sheet metal or other rigid material made substantially
in the manner, herein before described and securing the said dome shaped disc or body
with the attached bristles or wires to the stock or brush back substantially as described
and illustrated.
