1, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of Lancaster,
Patent Agent, do hereby declare the nature of this invention to be as follows :-
.
In certain types of apparatus for crushing and removing burrs and thistles from
wool and similar fibres, the crushing of the burrs and thistles is effected during the
passage of the fleece in a horizontal direction between a series of rollers placed side
by side.
Whilst employing similar means and devices, I arrange the sets of rollers under
each other so as to obtain a vertical motion of the fleece. In order to prevent tho
crushed burrs and thistles being dragged along by the crushing cylinders, I furnish
these with knives or scrapers which throw the crushed matters into a trough or
receptacles. The wool is delivered into a box. The object of the vertical arrangement
of the rollers is in combination with the additional details hereinafter described, is to
obtain a result superior to that which can be obtained by the use of the apparatus as
usually constructed.
In an apparatus constructed according to these Improvements the wool is delivered
to and spread upon an inclined endless travelling apron which carries it over a series
of pairs of drawing rollers arranged vertically over each other and between which
the wool is delivered. The upper pair of rollers is fitted with needle points and the
remaining drawing rollers are covered with india-rubber. The number, diameter and
speed of these rollers may be varied to suit the character of the wool and of the work.
The crushing rollers are placed immediately below the drawing rollers and below these
the doffing rollers are mounted. The wool falls from the doffers upon an horizontal
endless travelling table by means of which it is carried to suitably placed trucks or
boxes.

page_text: The knives or scrapers before referred to and which are employed to remove the
crushed burrs and thistles, are fixed so that their edges are in proximity with the
surfaces of the crushing rollers at points respectively nearly opposite those parts of
their circumference which are at the moment effective, or in contact. The crushed
burrs or thistles are thus scraped or removed from the crushing rollers and may be
collected in suitable receptacles.

I, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of Lancaster,
Patent Agent, 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 :-
In certain types of apparatus for removing burrs and thistles from wool and similar
fibres, the crushing of the burrs and thistles is effected during the passage of the wool
in the form of a fleece or film in a horizontal direction between a series of pairs of
rollers placed side by side.
According to these Improvements, a different arrangement of rollors is employed
and they are placed upon each side of a vertical plane through which the wool falls,
under the combined action of the rollers and of gravity.
I will proceed to particularly describe this Invention with reference to the accom-
panying drawing which represents in vertical section the essential details of the
apparatus; the framing, driving gear, and other accessories being omitted for the sake
of greater clearness, and also because the construction and arrangements of those
accessories are well known.
In an apparatus constructed according to these Improvements, the wool is delivered
to and spread upon an endless travelling apron A, which delivers it above and between
the two upper rollers B B¹ of the series of vertical rollers. These rollers are clothed
with wire cards or with needle points; the drawing rollers 1 1 immediately below the
card rollers, and the crushing rollers are each clothed with indiarubber or other
similar elastic or yielding material. The number, diameter and speed of all these
rollers may be varied to suit the character and condition of the wool to be cleaned.

page_text: The doffing rollers D D' are placed wider apart than the upper rollers and imme-
diately below the crushing rollers. The cleaned wool is doffed from the rollers CC
by the doffers D D' and falls upon a horizontal endless travelling table E which
delivers it to any desired position, as for example into the truck F. At the back of
each of the crushing rollers there is fixed a knife or scraper H with its edge bearing
upon the surface of the roller so as to clear therefrom the debris which clings to it
after passing the doffer. Below each knife there is a trough or receptacle G into
which the debris removed by the knife is received, and from whence it may from time
to time be removed.
When the apparatus is in operation, the wool is formed into a fleece or film.by
means of the rollers B B'; this fleece is then drawn and guided by the intermediate
rollers II and delivered to the crushing rollers C C'. The crushed thistles, burrs,
and other debris with a portion of the wool, adhere to the surface of the rollers and
are carried forward by their revolution until such of the wool as clings to them is
removed by the doffers and added to the bulk on the apron E. The crushed burrs and
other debris is not removed by the doffers but is carried forwards until it is removed
by the knives H H into the receptacles G G.
The hereinbefore described combination and arrangement of the apparatus gives a
result suporior to that which can be obtained by the use of similar apparatus as at
present constructed, and occupies only a small amount of floor space.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, as communicated to me
from abroad, I declare that what 1 claim is :—
(1) An apparatus for removing burrs and thistles from wool and similar fibres,
constructed arranged and operated substantially as hereinbefore described and as
illustrated by the accompanying drawing.
(2) In an apparatus for removing burrs and thistles from wool and similar fibres,
the combination and arrangement of the vertically disposed carding drawing crushing
and doffing rollers, with the knives H H, the receptacles G G, and the endless
travelling apron E, all substantially as hereinbefore described and as illustrated by
the accompanying drawings.
