Improvements in Brushes.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 relates to brushes, and particularly to that class used for cleaning
metal, wood, cloth and the like; and my invention consists of the constructions and
combinations of devices hereinafter fully described.
To enable others skilled in the art to which my invention appertains to make and
use the same, I will now describe its construction, and indicate the manner in which
the same is carried out.
In the accompanying drawing
Figure 1 is a side elevation of my improved brush.
Figure 2 is a transverse sectional view of the same and
Figure 3 is a detail showing one of the independent brushes removed.
A represents an arbor provided with flanges or nuts a, between which the brush B
is secured, said brush being securely fixed to the arbor, so that it may rotate with it
at a high rate of speed. The brush B consists of two end discs or flanges b, each of
which is formed or provided with a double series of perforations c and d, respectively,
and also with an inwardly-extending hub e, and between said discs or flanges the
independent brushes are mounted. Each independent brush consists of a head C,
which is formed with short pintles y on opposite sides, which are designed to loosely
fit the perforation in the discs, whereby the independent brushes have a free move-
ment about these pintles. Each head is also formed with sockets h, in which the
wires D or bristles, strips of leather, or analogous material are arranged in tufts, the
inner bent ends being fitted in the base of the sockets, and held therein by the pins l,
which are passed transversely through the head and the bent portions of the tufts of
wires therein. By mounting the heads loosely within and between the discs b, the
independent brushes work freely and hang down, resting upon each other when the
brush is idle; but when the brush is rotated the centrifugal force causes their outer
ends to be thrown outward and to assume the position shown in Figure 1. This
construction enables the brush to be used for a greater length of time than when they
are rigidly held, and reduces the wearing and breaking of the same to a minimum, as
the brushes readily yield to any irregularity in the surface of the part being
operated upon.
By using the double series of perforations for the journals of the brushes, and
arranging them in the manner shown, the independent brushes are prevented from
striking each other while in operation, and shorter lengths of wires may be used.
A brush constructed as described, will thoroughly clean metal plates, wood, cloth,
and like articles very quickly, and may be readily taken apart, and one or more of
the independent brushes or tufts of wire removed and new ones substituted.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim is :-
First. A metal or other cleaning-brush consisting of two transversely-perforated
end discs, the heads C, mounted between said discs and having sockets h and short
pintles loosely fitted in the perforations, whereby said heads have a free pivotal

page_text: movement, and tufts of wires secured in said sockete, substantially as herein
described.
Second. In a brush having separable end discs provided with a double series of
perforations, pivoted heads mounted between said discs, having sockets for the
reception of tufts of abrading material, and short pintles fitted in the perforations in
the discs, substantially as herein described.
Dated this 5th day of December 1890.
