Improvements in the Manufacture of Metal Shavings for Cleaning and
Polishing purposes and Apparatus for that purpose.
I, FRIEDRICH WILHELM BÜHNE, a subject of the Grand-Duke of Baden, and
resident of 17, Erbprinzen-street, Freiburg, in the Grand-Duchy of Baden in
the German Empire, Manufacturer, do hereby declare the nature of this inven-
tion to be as follows:-
Metallic shavings for cleaning and polishing purposes have hitherto been
produced by cutting them from thin metal wires or turning them off from metal
discs having the thickness of the shavings to be cut from them.
These two methods are not economical and there result from them shavings
of but little elasticity and sufficient sharpness on account of the smoothness of
the surfaces of the metal from which they are made.
The
The object of my invention is to obviate these disadvantages and to produce
shavings of great sharpness and elasticity in a very economical manner.
main feature of my improved method consists in cutting the metal from which
the shavings are produced parallel to its grain or fibre, the metal being in the
shape of rings or bands which are rotated and have such breadth that several
shavings are cut at a time.
For manufacturing shavings according to this method, especially for cutting
them off from the edge of a coiled metal band, I prefer to make use of the
machine illustrated in the accompanying drawings, in the several figures of
which similar letters denote similar parts.
Fig. 1 is a front view partly sectional
Fig. 2 a side elevation, and
Fig. a plan of the machine,
Fig. 4 indicates by a dotted line 5 the cut from a coiled band (4).
1 is the wound-up band which is held by moveable clamps or clutches 2.
When the band rotates shavings are cut off by means of radial cutters 3
and 31 which are held in carriers ₺ and 6¹ sliding in boxes 7 and 71 and pressed
outwards by springs 8 and 8¹.
Arms 9 and 91 which carry rollers 10 and 10¹ are arranged at the back-part
of the cutter-holders, and the rollers 10 and 10¹ are pressed against a ring 11
by the springs 8 and 81. The ring 11 has the shape of the coiled band 1 and is
fixed to a drum 12.
When the drum 12 with the band 1 is rotated by means of the driving
pulley 13 and the gear 14, 15, 16, 17, the spirally shaped ring 11, which is fixed
to the drum 12, acting on the rollers 10, 10¹ guides the cutters 3, 31 exactly in
the longitudinal direction of the band.
The shavings follow then the grain or fibre of the band and are cut off the
band by the whole working surface of the cutters 3 and 31.
The boxes 7 and 71 are mounted on supports 18 and 18¹ and can be moved
lengthwise by spindles 19 and 191 rotated by the gear-wheels 20, 21, 21, 22, 22',

whole material of the band is completely cut into shavings. The clamps 2
holding the band 1 move back gradually, according to the thickness of the
shaving.
This movement of the clamps 2, the ends of which latter are screw-threaded,
is effected by wheels 23 and 231 internally screw-threaded, and by the wheels 24
which successively pass a pin 25, being thus caused to rotate a little and screw
the clamps 2 back.
The drum may obviously be arranged horizontally or inclined instead of
vertically and the movement may be given ether to the drum or to the cutters.

I, FRIEDRICH WILHELM BÜHNE, a subject of the Grand-Duke of Baden, and
resident of 17, Erbprinzen-street, Freiburg, in the Grand-Duchy of Baden in
the German Empire, Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:―
Metallic shavings for cleaning and polishing purposes have hitherto been
produced by cutting them from thin metal wires or turning them off from metal
discs having the thickness of the shavings to be cut from them.
These two methods are not economical and there result from them shavings
of but little elasticity and sufficient sharpness on account of the smoothness of

The object of my invention is to obviate these disadvantages and to produce
shavings of great sharpness and elasticity in a very economical manner.
main feature of my improved method consists in cutting the metal from which
the shavings are produced parallel to its grain or fibre, the metal being in the
shape of rings or bands which are rotated and have such breadth that several
shavings are cut at a time.
For manufacturing shavings according to this method, especially for cutting
them off from the edge of a coiled metal band, I prefer to make use of the
machine illustrated in the drawings accompanying my Provisional Specification
in the several figures of which similar letters denote similar parts.
Fig. 1 is a front view partly sectional,
Fig. 2 a side elevation and
Fig. 3 a plan of the machine,
Fig. 4 indicates by a dotted line 5 the cut from a coiled band (4).

When the band rotates shavings are cut off by means of radial cutters 3
and 31 which are held in carriers 6 and 6¹ sliding in boxes 7 and 7¹ and pressed
outwards by springs 8 and 8¹.
Arms 9 and 91 which carry rollers 10 and 10¹ are arranged at the back-part
of the cutter-holders, and the rollers 10 and 10' are pressed against a ring 11
by the springs 8 and 81. The ring 11 has the shape of the outside of the coiled
band 1 and is fixed to a drum 12.
When the drum 12 with the band 1 is rotated by means of the driving

to the drum 12 acting on the rollers 10, 10' guides the cutters 3, 31 exactly in
the longitudinal direction of the band.
The shavings follow then the grain or fibre of the band and are cut off the
band by the whole working surface of the cutters 3 and 3¹.
The boxes 7 and 71 are mounted on supports 18 and 18¹ and ean be moved
lengthwise by spindles 19 and 191 rotated by the gear-wheels 20, 21, 21, 22, 22¹,
the cutters 3 and 31 being thus always pressed against the band 1 until the
whole material of the band is completely cut into shavings. The clamps 2
holding the band 1 move back gradually according to the thickness of the
shaving.
This movement of the clamps 2, the ends of which latter are screw-threaded,
is effected by wheels 23 and 231 internally screw-threaded, and by the wheels 24
which successively pass a pin 25, being thus caused to rotate a little and screw
the clamps 2 back.
The drum may obviously be arranged horizontally or inclined instead of
vertically and the movement may be given either to the drum or to the cutters.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is:
:-
1. The herein described method of manufacturing metallic shavings for clean-
ing and polishing purposes by turning them off in the line of the grain or fibre
of the metal blank, the thickness of the latter being a multiple of the width of
each individual shaving.
2. For operating as above set forth a machine constructed and arranged sub-
stantially as described with reference to the drawings.
