Improvements in Rotary Brushes.
I, ANTOINE DUMAS-GARDEUX, of 27, Rue Geoffroy Langevin, Paris, in the
Republic of France, 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 relates to rotary brushes the object being to allow of easily
regulating the resistance or flexibility of the brushes, to increase their strength and
consequently their duration and to admit of one or more of the parts or sections of
such brushes being changed as required when worn.
In the accompanying drawings which illustrate the various applications and
modifications of my invention ;-
Figure 1 is an elevation partly in section of a rotary brush made according to
my invention of iron, steel or copper wire with wooden plates or cheeks connected
by screws or bolts:
Figure 2 is a section of a brush with a central rod mounted on a screw threaded
tube with nuts :
Figure 3 is an elevation partly in section of a brush with interposed distance
rings:
Figure 4 is a continuous brush on an iron rod :
Figure 5 is a face view of a disc (forming one of the parts or sections of a brush)
with wire or bristle tufts :
Figure 6 is a similar view of a disc with flat strips of steel instead of wire or
bristles:
Figure 7 is a similar view of half a disc provided with looped wire tufts.
To enable the principle of my invention to be fully understood I will refer first
to Figures 5, 6 and 7. These figures each represent one of the parts or sections of
the brush. Each part or section is formed of a disc or ring a of suitable material
such as leather, paper, cloth or metal. This disc or ring is provided with holes b,
Figures 5 and 7, or with slots e Figure 6. These holes can be fitted or not with
eyelets & Figure 5 to strengthen them. Through these holes or slots c are passed
the tufts e formed of wire or other material which are then folded or doubled over
as in Figure 5 or the tufts can be looped as shewn in Figure 7; if flat steel strips f
Figure 6 are employed instead of tufts they are passed through the slots c and then
folded or doubled over.
On each side of the discs or rings provided with the wire or other tufts I place
metal plates or rings A Figure 3 of suitable size, so as to give more or less flexi-
bility to the outer wires or bristles B or to allow, by replacing them with smaller
ones, of using up the wires or bristles B to the very farthest extent. These discs
or rings fitted with wire or other suitable material can be mounted in various ways
according to the purposes and industries for which they are to be used.
In Figure 1 I have shewn a brush composed of several discs or rings C held
between two cheeks or plates of wood D connected by means of bolts or screws E.
Figure 2 shews the arrangement of discs or rings N fitted with wire or bristles
and mounted upon a screw threaded tube F through which passes a round rod R
serving as a shaft or handle.
In Figure 3 the discs or rings F, F provided with wire or the like are held at a
certain distance apart from one another by interposed rings G bearing against the
side plates or discs H. The whole is passed on to a round or square metal rod I
serving as a shaft or handle and provided with protecting cones J.

page_text: Figure 4 shews a continuous rotary brush in which the discs or rings carrying
the wire are juxtaposed and are mounted upon a rod K carrying a disc or plate L
serving to abut against the wires or the like of the end discs or rings, a stop nut L¹
and a tightening nut M.
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 rotary wire or other brushes constructing the parts or sections of such
brushes of discs or rings of leather, wood, paper, inetal or the like substantially in
the manner herein before described and illustrated in the accompanying drawing.
2. In rotary wire or other brushes the discs or rings composing the wire or strip
carrying sections provided with holes through which the wires, strips or the like
are passed and folded or doubled over or formed into loops substantially as herein-
before described and illustrated in the accompanying drawing.
3. In rotary wire or other brushes discs or rings provided with wires, strips or
the like and with side plates or discs of suitable size for varying the flexibility of
the wires or the like of the brush, and allowing, by replacing them by smaller
ones, of using up the wire or the like to the very farthest extent substantially as
hereinbefore described and illustrated in the accompanying drawing.
4. In rotary wire or other brushes the wire or strip carrying discs or rings
separated by interposed rings serving to keep thein at a distance apart
substantially as hereinbefore described and illustrated in Figure 3 of the
accompanying drawing.
5. In a rotary wire or other brush mounting the tuft carrying discs or rings
either in a continuous manner or at a distance apart upon screw threaded tubes or
rods or upon plain, square or round rods on which they are secured by plates
or rings and nuts substantially as hereinbefore described and illustrated in the
accompanying drawing.
6. In a rotary metal or other brush the discs or rings serving as holders for the
metal wires, bristles, hair or the like having holes or slots for receiving the latter
fitted with eyelets in order to strengthen them and render them durable
substantially as hereinbefore described and illustrated in Figure 5 of the
accompanying drawing.
7. The improved rotary brushes hereinbefore described and illustrated in the
accompanying drawing.
