Improvements in Machinery for Drilling Brush Bodies, and Setting
the Bristles therein.
I, CARL EDUARD FLEMMING, of Schoenheide, Germany, Brush Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a construction of the lower part of a machine for drilling
brush bodies and setting the bristles therein, which contains working tables that cau
reciprocate both in the longitudinal and the transverse direction, and that are
connected so as to move together, the actuating gear of which machine for producing
the said reciprocating motion is driven by a face-cam-disc so that both tables perform
exactly the saine movements, for bringing the brush bodies carried thereby into
exactly the same positions relatively to the drilling or setting tools, arranged parallel
with each other. Such a construction was described in the Specification to my
application of 7th August 1896 No. 17491.
The present improvements have for their object to impart by means of a single
face-cam disc any desired extent of both longitudinal and transverse reciprocating
motion to the working tables, and thus to enable similar patterns of brush body
surfaces of any desired extent, that require to be drilled or set with bristles, to be
produced by means of a single face-cam disc.
On the accompanying drawing is shewn the construction of the lower part of a
machine for drilling and setting bristles in brush bodies constructed according to this
invention.
Figure 1 shews a side elevation,
Figure 2 an end view, and
Figure 3 a plan.
The framing of the machine is marked 8, the face-cam disc t, the working tables a
and the double slide for effecting the uniform motion of the latter d d and d d¹.
In the construction here shewn by way of example for producing any required
extent of reciprocating motion of the working tables, both in the longitudinal and the
transverse direction, the notion is transmitted from the face-cam disc t to the
slides d d and d d' and to the working tables a a, by means of interchangeable devices
that alter the ratio of transmission.
The toothed rack y which receives a vertical sliding motion from the face-can
disc t imparts its motion to the foothed wheel z² fixed on the shaft u' carried in
bearings ; the wheel z gears with the toothed wheel T rotatably mounted on an
axis B, which can be fixed by means of a screw nut B' in any desired position in
a curved slot on the frame-bracket & t, arranged concentrically to the shaft u.
The wheel T transmits its rotary motion through the toothed wheel to the
toothed wheel 2, 3 being interchangeably arranged upon the shaft us carried in
bearings u² u².
The toothed wheel z' gears with a toothed rack cut in the under surface of the top

page_text: slide d d, and thus effects the horizontally sliding motion of this slide, that is to say
the longitudinal reciprocating motion of the working tables a a connected
thereto.
As the wheel 2 can be changed, the sliding motion of the double slide can be
extended or shortened at will, thus increasing or decreasing the extent of longitudinal
reciprocating motion of the tables a a.
The movement of the under slide d d in the transverse direction of the brush
body is also effected from the disc cam t,, which imparts a horizontal sliding motion
to the sliding piece v and the steel bar a in a direction at right angles to the motion
of the upper slide d d.
For obtaining any desired extent of reciprocating motion of the working tables a a
in the transverse direction, the bar has its free end carried in a guide-bearing w;
it is engaged by means of a stud 1 or by a roller thereon, in a loop of the swing-
ing arın k, which transmits its swinging motion to the lower slide d d by means of
the connecting rod k pivotally connected at 6' to the arm k and at 62 to the lower
slide d d¹.
The pivot b' of the arm k is adjustable in the loop k", whereby the effective length
of the lever arm, and consequently also the extent of the motion, can be varied at
will.
The sliding motion of the under-slide d d, and consequently the reciprocating
motion in the transverse direction of the working tables a a connected therewith,,
will correspond to the extent of the swinging motion of the arm k.

Improvements in Machinery for Drilling Brush Bodies, and Setting
the Bristles therein.
I, CARL EDUARD FLEMMING, of Schoenheide, Germany, Brush 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 :-
This invention relates to a construction of the lower part of a machine for drilling
brush bodies and setting the bristles therein, which contains working tables that can
. reciprocate both in the longitudinal and the transverse direction, and that are
connected so as to move together, the actuating gear of which machine for producing
the said reciprocating notior. is driven by a face cam disc so that both tables perform
exactly the same movements, for bringing the brush bodies carried thereby into exactly
the same positions relatively to the drilling or setting tools, arranged parallel with
each other. Such a construction was described in the Specification to my application of
7th August 1896 No. 17491.
The present improvements have for their object to impart by means of a single
face-cam disc any desired extent of both longitudinal and transverse reciprocating
motion to the working tables, and thus to enable similar patterns of brush body
surfaces of any desired extent, that require to be drilled or set with bristles, to be
produced by means of a single face-cam disc.
On the drawing accompanying my Provisional Specification is shewn the con-
struction of the lower part of a machine for drilling and. setting bristles in brush
bodies constructed according to this invention.

page_text: Figure 2 and end view, and
Figure 3 a plan.
The framing of the machine is marked 8 the face-cam disc t, the working tables a
and the double slide for effecting the uniform motion of the latter d d and d d¹.
In the construction here shewn by way of example for producing any required
extent of reciprocating motion of the working tables, both in the longitudinal and
the transverse direction, the motion is transmitted from the face-cam disc t to the
slides d d and d d¹ and to the working tables a a, by means of interchangeable devices
that alter the ratio of transmission.
The toothed rack y which receives a vertical sliding motion from the face-cam
disc inparts its motion to the toothed wheel z lixed on the shaft ut carried in
bearings ; the wheel gears with the toothed wheel T rotatably mounted on an
axis B, which can be fixed by means of a screw nut B¹ in any desired position in a
curved slot on the frame-bracket & t, arranged concentrically to the shaft u
The wheel T transinits its rotary motion through the toothed wheel 2' to the toothed
wheel, being interchangeably arranged upon the shaft u³ carried in
bearings u² u².
The toothed wheel 21 gears with a toothed rack cut in the under surface of the top
slide d d, and thus effects the horizontally sliding motion of this slide, that is to say,
the longitudinal reciprocating motion of the working tables a a connected thereto.
As the wheel 23 can be changed, the sliding motion of the double slide can be
extended or shortened at will, thus increasing or decreasing the extent of longitudinal
reciprocating motion of the tables a a.
The movement of the under slide d d¹ in the transverse direction of the brush body
is also effected from the disc cam t, which imparts a horizontal sliding motion to the
sliding piece and the steel bar x in a direction at right angles to the notion of the
upper slide d d.
For obtaining any desired extent of reciprocating motion of the working tables a a in
the transverse direction, the bar x has its free end carried in a guide-bearing w; it is
engaged by means of a stud 1 or by a roller thereon, in a loop of the swinging arm k,
which transmits its swinging motion to the lower slide d d' by means of the connecting
rod k pivotally connected at 63 to the arm k and at 62 to the lower slide d d'.
The pivot 6 of the arm k is adjustable in the loop kn, whereby the effective length
of the lever arm, and consequently also the extent of the motion, can be varied at
will.
The sliding motion of the under slide d d', and consequently the reciprocating
motion in the transverse direction of the working tables a a connected therewith, will
correspond to the extent of the swinging motion of the arm k.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
In a machine for drilling brush bodies and setting bristles therein, having con-
nected working tables receiving a prescribed reciprocating motion the driving
mechanism of which receives motion from a face-cam disc transmitting the motion
froin the face-cam disc t, to the slides d d and d d', or to the working tables a a by
means of interchangeable devices that alter the ratio of transmission, substantially as
described.
