Improvement in Unburring Devices for Deviling Machines and
Carding Engines.
I PETER LUDWIG KLEIN of Düsseldorf in the Kingdom of Prussia and Empire
of Germany, Machine Maker 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 reference being had to the accompanying drawings,
in which:-
Figure 1, sheet 1, is a sectional elevation of my improved device as applied to a
Deviling Machine, and
Figure 2, sheet 2, is a similar view of the same, applied to a Carding Engine.
Like letters of reference indicate like parts in both figures.
a is a feed-apron by which the material is carried in the usual way to a first pair
of feed-rollers b, 61, which pass it to the second pair of feed-rollers c, c', from which
the material is taken by the first burring-roller d, a clearing roller c³, situated above
the feed-roller c', removing from the latter, any fibres remaining thereon, and passing
them to the burring-roller d. Above the clearing roller c³, and a suitably arranged
pan 1, revolves a beating roller e, which serves to beat off from the material passing
over the burring-roller d, and into the pan 1, such burrs and impurities as have, by
the teeth of the roller d and the feeding-rollers b, c, been brought to the surface of
the material; this heating roller e, being situated above the axis of the burring-
roller d in contradistinction to its being below the same. A drawing-roller is
arranged above the burring-roller d, and between it and the next burring-roller g.
Above the axis of the burring-roller d, or behind the same, are arranged a series
of burring-rollers g, k, n, q, together with a series of beating-rollers h, 1, o, r, arranged
above the axis of their respective burring-rollers and a series of drawing-rollers i, m, p.
the beating-rollers and drawing-rollers acting in connection with their respective
burring-rollers in precisely the same manner as the beating-roller e and the drawing-
roller and in connection with the burring-roller d.
When my device is applied to a Deviling-machine as shewn in Figure 1, a brush-
roller S is arranged relatively to the burring-roller q and provided with bristles, which
brushing into the teeth of the burring-roller q, remove the unburred material from

page_text: the same, and a receptacle Z, provided with 2 openings, arranged relatively to the
burring-rollers g, n, and beating-rollers k, o, so as to receive the burrs and other
impurities beaten off from the material by the latter, while pans 2 and 3 serve to
like purpose with regard to the burring-rollers k and y and beating rollers I and r.
The number of burring-, drawing-, and beating rollers, which may be used, is
determined by the material passed through the device, and by the application of the
device to either a Deviling Machine or a Carding Engine, and may be varied according
to circumstances.
In Figure 1 I have shown the improved device as arranged for use with a Deviling
Machine, the burring rollers being arranged above each other, while for use with a
Carding Engine, as shown in Figure 2, they are arranged behind each other; but
in either case the beating-rollers must be situated above the axis of their respective
burring-rollers, their operation being exactly the same in both cases.
The material is carried by the fecd-apron a to the feed rollers b, b, which as shewn
in my patent No. 116 of January 10th 1881 are provided with teeth placed in spiral
rows, inclined or running in opposite directions, so that the teeth will intermesh and
with grooves in their surfaces corresponding to and between the spiral rows of teeth
in such a manner, that the teeth of the one roller are opposite to and move in the
grooves of the opposite roller. But while in my aforesaid patent the rollers of each
pair of feed-rollers have the same circumferential speed, having equal diameter and
axial speed, in this case the feed-roller b¹ has double the diameter of roller b, both
revolving at the same axial speed, in consequence of which the roller b¹ has double the
circumferential speed as that of roller b, thereby causing a sweeping action of the
teeth of roller 61 in the grooves between the teeth of roller b. By means of this
weeping action of the teeth of roller b¹ the fibres of the upper surface of the material
in the grooves of roller bare straightened out in the direction of their length, and
the burrs contained in the same loosened therefrom. The feed-rollers c, c', functionate
in an analogous manner, but have double the axial and circumferential speed
respectively of the rollers b, b¹, the teeth of the roller c in this case having the
sweeping action in the grooves of rollers c¹ straightening the fibres of the lower
surface of the material, and loosening the burrs contained in the same.
The greater
circumferential speed of the rollers c, c¹, causes a drawing out of the material between
the rollers b,, and c, c', whereby a further loosening of the burrs is effected. It
will be observed, that while between the rollers b, the upper surface of the material
is affected by the sweeping action of the teeth of roller 61, this action is exerted on the
fibres of the lower surface of the material between the rollers C, c¹.
The burrs loosened by the sweeping action of the teeth of the rollers 61 and c in the
spiral grooves of the rollers b and c as well as by the drawing out of the material
between the rollers b, b and c, c¹ and which, lying in the spiral grooves, can not be
reached by the teeth of the burring-roller d are passed unbroken and lying loosely on
the material with the latter to the burring-roller d and are easily beaten off by the
beating-roller e into the pan 1. By reason of its greater circumferential speed the
burring-roller d takes the material from. the feed-rollers c, c', the clearing-roller
removing any fibres remaining on the roller c¹ and passing them to the burring-
roller d. The beating-roller e removes the burrs lying loosely on the material passing
over the burring-roller d and throws them into the pan 1. The drawing roller has
the same circumferential speed as the burring-roller d, while the second burring-
roller g has a greater circumferential speed than the burring-roller d and consequently
takes the entire material from the latter, whereby the upper surface of the material is
drawn through the teeth of the drawing-roller f, parallelized, drawn out, and its fibres
drawn away from a large portion of the burrs still adhering to the material, these
burrs finding resistance in the teeth of the drawing-roller f; and thus the entire
material, completely turned, passes to the burring-roller g, that the surface of the
material, which on the roller d has been the upper and outer one, now becoming the
lower and inner one on the roller g, while that, which on roller d was the lower
and inner one, now becomes the upper and outer one on roller g. By means of this
complete turning of the material, the burrs which have been loosened by the feed-

page_text: roller b, b, c, c¹, and which on the roller d adhered to the lower surface of the material,
and, being covered by the same, could not therefore be reached by the beating-roller e are
now on the surface of the material on the burring-roller g and they as well as those burrs
which have been loosened by the drawing-roller fare for the greater part beaten off
by the beating-roller h and thrown into the receptacle z. The next burring-roller k
has again a greater circumferential speed than that of the burring roller g and therefore
takes the entire material from the latter, whereby it is again completely turned in such
a manner, that the surface of the material, which on roller g was the lower and inner
one, is the outer and upper one on roller k, while at the same time the upper surface
coming from the roller g is drawn out and parallelized by the teeth of the drawing-
roller and the burrs, which have not been thrown off by the beating-roller h, drawn
out of the fibres of the material by reason of the resistance they find against the teeth
of said roller i. The burrs which have not come to the surface through the taking of
the entire material from the roller g and turning it by the roller k, and those which
have been loosened and freed by the action of the drawing-roller i are now beaten off
by the beating-roller / into the pan 2.
The burring-roller n with the beating-roller o and the burring-roller q with the
beating-roller r in combination with the drawing-rollers m and p operate in an
analagous manner to that of the burring-rollers d, g, k, heating-rollers e, hand drawing-
rollers f, i.
The arrangement of the beating-rollers above the axis of their respective burring-
rollers is an important feature of my improvements, especially when the same is
applied to Carding Engines, in which case the burring-rollers are not arranged in a
vertical line above each other, but behind and alternately a little below each other, in
order to allow room for the beating rollers. This arrangement of the beating-rollers
above the axis of their respective bearing-rollers prevents and saves an enormous
amount of waste, for by this arrangement any fibres of the material which are beaten
off by the beating-rollers in their action, fall back upon the material and remain in
the same, while when the beating-rollers are arranged below the axis of their
respective burring-rollers, the fibres beat off by them would fall either to the ground,
or with the impurities and would in either case be waste.
The burring-rollers d, g, k, n, q, revolve alternately in opposite direction, by means
whereof the entire material is turned, without the necessity of using separate turning-
rollers, four times, and drawn out three times on one surface, and twice on the other
surface, until it is brushed off by the brush-roller s. It will be observed, that the
burring-rollers revolve alternately in the opposite direction, in order that the material
may be entirely turned each time in passing from one burring-roller to the next one.
The bristles of the brush roller s, which latter has a greater circumferential speed
than the burring-roller q brushes the now unburred material off from the teeth of the
latter. This brush-roller comes into use however only when my improved device is
used in connecting with a Deviling Machine.
The advantages of my improved device are as follows.
The entire material is completely turned each time in passing from one burring-
roller to the next one, without the use of intermediate turning-rollers, while at the
same time the arrangement of the beating-rollers above the axis of their respective
burring-rollers prevents any waste of the material, the fibres beaten off by the beating-
rollers, falling back upon the material passing over the several rollers and remaining
in the same, instead of falling to the ground and being wasted.
By reason of this turning of the material each time in passing from one burring-
roller to the next one, both surfaces of the material are alternately acted upon by the
drawing-, burring-, and beater-rollers, thereby not only more thoroughly cleansing it,
but also more evenly drawn out and parallelizing all the fibres of the entire mass of
the material, than would be the case, if the material were not alternately turned.
By reason of the difference in the circumferential speed of the two rollers of each
pair of feed-rollers, a sweeping action of the teeth of the one roller in the corre-
sponding grooves of the other roller is produced, by means of which the fibres of the
material are straightened in the direction of their length and the burrs loosened from

page_text: he fibres, one surface of the material being thus operated upon by the first pair of
feed-rollers, while the second pair of feed-rollers operates upon its other surface, thus
subjecting the entire material to the said sweeping action of the respective rollers of
both pair of feed-rollers, while a stretching of the material is effected by the difference
in the circumferential speed of each pair of feed-rollers.
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. An Unburring Device for Deviling Machines and Carding Engines, in which
the material passes a series of burring-rollers in such a manner, that each time in
passing from one burring roller to the next, it is completely turned, and in which all
the beating-rollers are arranged above the axis of their respective burring-rollers, in
contra distinction to being arranged below the same, substantially as and for the
purpose described.
2. The feed-rollers b, b, c, c', provided with spiral grooves and arranged in pairs, the
rollers of each pair revolving at different circumferential speed, and the second pair
having a greater circumferential speed than the first pair, substantially as and for the
purpose set forth.

3. The combination with a series of burring-rollers revolving alternately in
opposite direction and at consecutively increasing speed, of the feed-rollers 6, 61,
provided with spiral grooves and arranged in pairs, the rollers of each pair revolving
at different circumferential speed, and the second pair having a greater circum-
ferential speed than the first, substantially as and for the purpose set forth.
