Improvements in Brushes.
I, GEORG JULIUS BEISSBARTH, of Nuremberg, in the German Empire,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to brushes for colouring or painting and the like, and the
object of the same is, not only to fasten the hairs unto the handle in an exceptional
firm manner, but also to allow for an easy replacing the worn-off hairs by new ones.
As to this latter consideration ny new brush will be found an especially welcome
improvement, it being in very many instances of great importance, to be able to
replace the hairs of a brush, without having to throw away the handle. I draw
attention for instance to the common painting of iron in boiler- or bridge-shops.
where the large surfaces are rusty or rough, which tears away the hairs of brushes
in almost no time. In such and similar branches of industry it is scarcely necessary
to hint at the great saving, when the hairs of the brush can be replaced and the
handle be made use of over and over again.
In order to make my invention more clear, I refer to the accompanying drawing,
in which:
Fig. 1 is a view of the complete brush,
Fig. 2 a sectional side-view of the same,
Figs. 3 & 4 are details showing the handle separately,
Figs. 5 & 6 show the tightening appliance hereinafter more fully described.
A is the handle of the brush, which terminates into a wedge-like extension w,
provided with shoulders s.

for purposes hereinafter explained. Finally, there are
metal rings E for tilting over the socket C and thus forming a proper termination
at the joint of the hairs or the handle. In order to fasten the hairs unto the handle,
they are firstly brought into the ring C, as many as might fill up the ring by
ordinary means, and drawn to one side, so that their rear ends are flush with the
outer or upper edge of the ring or socket C. Then the clamp D is inserted in
between the hairs from underneath, while the two blades of the same are held
together, in such a position, that the nozzles n rest against the inner or under edge
of the ring C and the prolongations p project out on top.
The handle A then is fixed by introducing the wedge in between the two blades
of the clamp D until the shoulders s knock against the upper edge of the ring C.
By a pin the clamp D is fastened to the handle. To prevent more effectually
hairs from slipping out on the smooth surface of the clamp, the same is provided
with small notches o. The hairs being split by the clamp D are brought together
again by the ring E, which is stripped over, so as to embrace the ring D. Then
the brush is completed and ready for use, as it is shown in Figs. 1 and 2.

Improvements in Brushes.
I, GEORG JULIUS BEISSBARTH of Nuremberg, in the German Empire,
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 brushes for colouring or painting and the like, and the
object of the same is, not only to fasten the hairs unto the handle in an exceptional
firm manner, but also to allow for an easy replacing the worn-off hairs by new ones.
As to this latter consideration my new brush will be found an especially welcome
improvement, it being in very many instances of great importance, to be able to
replace the hairs of a brush, without having to throw away the handle.
I draw attention for instance to the common painting of iron in boiler- or bridge-
shops, where the large surfaces are rusty or rough, which tears away the hairs of
brushes in almost no time. In such and similar branches of industry it is scarcely
necessary to hint at the great saving, when the hairs of the brush can be replaced
and the handle be made use of over and over again.
My new method of making these brushes is on an entirely new principle, quite
reverse to the old style of brushes now in use. In the old style as mentioned
before the bristles were simply tied upon the wooden handle with wire or string
while I drive my handles from behind into the bristles, that is between two blades
specially constructed and hereafter more fully described, and while my rings of
wire, string, or metal are first put around the bristles before the handle is driven
into the same.
In order to make my invention more clear, I refer to the drawings sent in with
Provisional Specification, in which :-
Fig. 1 is a view of a complete brush with one knot of bristles; brushes can be
made on same principle with two or more knots of bristles.
Fig. 2 is a sectional side view of the same.
Figs. 3 & 4 are details showing the handle separately.
Figs. 5 & 6 show the clamp or tightening appliance hereinafter more fully
described.
A is the handle of the brush, which may have any shape or form suitable for
other brushes of same nature. The handle of the brush terminates in a wedge-
like extension w provided with shoulders s. B are the hairs or bristles of the
brush and C is a metal or wire ring or socket, which embraces the bristles at their
rear ends.
D is a clamp made of sheet-iron, which may be galvanized or tinned,
or which can be made out of any other metal or material, bent under an angle, so
as to fit into the wedge w and provided with two prolongations p and two nozzles n
for purposes hereinafter explained.
This clamp may have any other shape or form as may be desired to suit the
purpose.
In order to fasten the hairs to the handle, they are firmly brought into the
ring C as many as might fill up the ring by ordinary means and drawn to one side
so that their rear ends are flush with the outer edge of the ring or socket C. Then
the clamp D is inserted between the hairs from above the ring C, while the two
blades of the same are held together in such a position, that the nozzles n project
above the ring thus keeping the same so as not to move out of its place, and the
prolongation p projects out on the wooden handle.
The handle A then is fixed by introducing and forcing the wedge we in between
the two blades of the clamp D until the shoulders & knock against the edge of the
ring C. By a pin i the clamp D is fastened to the handle.
To prevent more effectually hairs from slipping out on the smooth surface of
the clamp the same is provided with small notches o upon which the bristles have
a firm grip.

page_text: In order to make the bristles lie more closely together, a metal ring E is finally
drawn over the bristles B and the free edge of ring C. Then the brush is
completed and ready for use as is shown in Figs. 1 and 2.
By withdrawing pini and pulling the handle A and clamp D out of the ring C
the worn off hairs can be removed and new ones substituted for them.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In a brush The combination of a handle A, terminating in a wedge w, provided
with shoulders s, a ring C, a clamp D, having two nozzles n and fastened unto the
handle by a pin i after the brush-hairs being inserted, and ring E to strip over the
edge of the ring C from above or from beneath, substantially and for the purpose
as described.
