Improvements in Distemper or Whitewash Brushes.
I CHARLES HENRY HOBBS trading as F. R. Frinneby and Son of 75 Leonard
Street Finsbury in the City of London Manufacturer 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 :-
"
My Invention has for its object to provide a whitewash or distemper brush
which is free from liability to the bristles or fibres becoming separated or "forked
and to becoming loose and separated from the brush and also one in which the
bristles are arranged so that they are more effective in use than are those as hitherto
made.
I will describe my Invention with reference to the accompanying drawings.
Figure 1 of which shews partly in elevation and partly in section a brush mado
according to my Invention. Figures 2 and 3. are views at right angles to each
other of the handle for the brush and Figure 4 is a plan of the same. Figures 5
and 6 are a plan and a side view respectively of the band which surrounds the
root ends of the bristles or fibres.
The handle A is provided at top with a piece a upon which the root ends of the
bristles or fibres rest. This piece a is made of the shape shewn in Figure 4 with
narrow ends so that the bunches of bristles or fibres are not so thick towards the
ends, as they are in the middle. This gives a better effect in using the brush
than is the case where the bunches of bristles or fibres are as thick or nearly as thick at
the ends as they are in the middle. The blade a² which enters between the bunches of
bristles or fibres is made in one with the handle and does not extend the whole length of
the piece a but at each end terminates short thereof so as to leave a part at a³ at each
end against which as well as against the side portions of the part a the root ends
of the bristles or fibres rest so that the bristles or fibres extend all around the
brush. This prevents the "forking" of the bristles or fibres as the brush wears.
The bunches of bristles or fibres are cemented at their root ends and are placed around
the blade a² and then the metal (preferably copper) band B is placed on so that it covers
the edge of the piece a and also extends some distance up the root ends of the
bristles Rivets or nails are then driven through the metal band B and into the flat
of the part a and also through the metal band and through the cemented root
ends of the bunches of bristles or fibres into the blade a². When the brush is
finished it will be seen that the root ends of the bristles are covered by the band
which is firmly nailed to the part a which supports the bristles or fibres and gives
thorough protection thereto.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In distemper or whitewash brushes a part a of the shape shewn in Figure 4 so
that the bunches of bristles or fibres have a smaller thickness at the ends than they
have in the central parts substantially as hereinbefore described.
2. In distemper or whitewash brushes the part a with a blade a' which does not
extend the whole length of the part a but leaves ledges a³ for the reception of the
bristles or fibres substantially as hereinbefore described.
3. A distemper or whitewash brush constructed as hereinbefore described and
illustrated in the accompany drawings.
