COMPLETE SPECIFICATION.
An Improved Cylinder or Rotary Brush for use in Finishing Boots
and Shoes.
I, ARTHUR JAMES TRACKER, of the Firm trading as J. Thacker, of Nos. 3 and 5,
Shenton Street, Leicester, in the County of Leicester, Findings Merchant and
Shoe Mercer, being a communication from J. C. Ham and A. T. Condon, of The
Condon Manufacturing Co., Belfast, Maine, one of the United States of America,
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 relates to an improved cylinder or rotary brush for use in finish-
ing boots and shoes and the invention consists essentially in forming the brush
with strips of flexible material placed at intervals between the bristles preferably
non resilient in character. The ends of the bristles projecting beyond the ends of
the strips.
That this invention may be clearly understood a sheet of drawings accompanying
this specification, in which:
Figure is an end elevation of the brush partially formed and with a portion
in section.
Figure 2 is a longitudinal section of the brush, and
Figure 3 one of the bristles sections in perspective.
The bristles B are suitably secured in the brush and they have interposed
between them at intervals, strips of flexible material C which may be of chamois
skin or other suitable material.
The material to be used for the strips should be thin and be as little resilient
as possible.
The strips are preferably arranged parallel with the axis of rotation of the
brush, but they may be otherwise disposed as may be desired.
It will be seen in the drawings that the brush is made up of sections, each of
which is composed of a flat bunch of bristles to one side of which is secured the
strip C. Figure 3." The bases of the bristles are cemented to a transverse strip
of leather board, card board or other suitable rigid-material e, the ends & of which
project beyond the sides of the section and these ends are reinforced by other
thicknesses of similar material.
The strip C is cemented by its inner end to the base of the bristle section and
according to the construction herein illustrated, the outer end does not extend to
the ends of the bristles.
A two part hub A constitutes the body of the brush and in each half section is
an annular groove into which fit the projecting ends № of the bristle sections. The
two parts of the hub are fastened together by the screws a and they thus hold the
bristle section firmly in place.
A brush constructed in this manner is much more durable than one composed
wholly of bristles.
The effect of the strips is to support the bristle sections, to prevent them from

page_text: spreading and from bending down on to the hub when an excess of pressure is
exerted against, or placed on them. The said strips should be very Hexible so
as to yield readily when the bristles are pressed back by the work and with such
strips the centrifugal force caused by the high revolution of the brush on its shaft
will cause them to resist sufliciently the bending of the bristles and any resiliency
in the strips will make them too stiff and not sufficiently yielding.
The outer ends of the strips should be some distance back from the ends of the
bristles so that the latter will bend over the ends of the strips, otherwise the
strips and not the bristles would do the work of the brush.
"
It will be well understood that this invention can be applied to brushes made of
hair or any such like material, and the term bristles is to be understood as
including such material.
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. The herein described cylinder brush having strips of flexible material placed
at intervals between the bristles, the outer ends of the bristles extending beyond the
outer ends of the strips.
2. A cylinder or rotary brush having strips of flexible material placed at inter-
vals between the bristles, said strips extending transversely to the plane of rotation
of the brush, the outer ends of the bristles extending beyond the outer ends of the
strips, substantially as described.
3. A cylinder or rotary brush made up of a series of radial bristle sections
extending transversely to the plane of rotation, and strips of flexible materials inter-
posed between said sections, the outer ends of the bristles extending beyond the
outer ends of the strips, substantially as described.
4. A cylinder or rotary brush made up of a series of bristle sections, the base of
the bristles in each section being cemented to a transverse strip of rigid material
having projecting ends, a strip of flexible material cemented to the bristles at
the base thereof, in combination with a two-part grooved hub adapted to engage
the said projecting ends, substantially as herein described and set forth.
5. An improved cylinder or rotary brush for use at high speeds for use in
finishing boots and shoes, having strips of thin, flexible and non resilient material
placed at intervals between the bristles, substantially as herein before described and
set forth.
