Improvements in Means and Apparatus for Operating Fancy Rollers
of Carding Engines.
A communication to me from abroad by JoHN WILLIAM OLDROYD, Woollen
Manufacturer, and WILLIAM GOODALL, Carding Overlooker, both of
Grumberg, Silesia, in the Empire of Germany.
1, JOSEPH LAW of the firm of Samuel Law and Sons, Limited, Cleckheaton in
the County of York Card Clothing Makers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the fancy rollers of carding engines or machines for
carding wool, cotton, silk and other fibres, and is designed to ensure increased
utility from such roller; not only as to the fibres operated upon but in addition to
inhance the utility of the cards on the said roller and on the cylinder in connection
with which such fancy rollers work.
According to this invention the fancy rollers in additions to rotary motion have
combined therewith an attachment, operated by strap eccentric, or the equivalent of
the latter whereby an endwise reciprocating or traverse motion is given to the
said roller, the wire of which acts on the wire of the cylinder whereby the requisite
points of the teeth of the cards are maintained or renewed with the result that the
cylinder and fancy rollers are kept at level and true surface by a constant change
of surface contact, obviating "rows or markings on the cylinder; less fettling is
required and the cylinders are kept cleaner and require less grinding, and the
resulting yarn is more regular and even. As a means of imparting the required
motion I employ a worm driving a worm wheel fast to the boss of which is an
eccentric enclosed by a metal strap, an arm from the latter carries a pin or stud
and plate communicating to the fancy roller the desired endwise motion.

COMPLETE SPECIFICATION.
Improvements in Means and Apparatus for Operating Fancy Rollers
of Carding Engines.
I, JOSEPH LAW, of the firm of Samuel Law and Sons, Limited, Cleckheaton
in the County of York, Carding Clothing Makers, do hereby declare the nature of
this invention, which has been communicated to me from abroad by John William
Oldroyd, Woollen Manufacturer and William Goodall, Carding Overlooker, both
of Grumberg, Silesia in the Empire of Germany 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 the fancy rollers of carding engines or machines for
carding wool, cotton, silk and other fibres, and is designed to ensure increased
utility from such roller, not only as to the fibres operated upon but in addition to
enhance the utility of the cards on the said roller, and on the cylinder in connection
with which such fancy rollers work.
According to this invention the fancy rollers in addition to rotary motion have
combined therewith an attachment operated by strap eccentric, or the equivalent of
the latter whereby an endwise reciprocating or traverse motion is given to the
said roller, the wires of which act on the wires of the cylinder whereby the

requisite points of the teeth of the cards are maintained or renewed with the result
that the cylinder and fancy rollers are kept at level and true surface by a constant
change of surface contact, obviating "rows or markings on the cylinder; less
fettling is required and the cylinders are kept cleaner and require less grinding, and
the resulting yarn is more regular and even. As a means of imparting the required
motion 1 employ a worm driving a worm wheel fast to the boss of which is an
eccentric enclosed by a metal strap, and the latter is carried by au arm working on
a fulcrum, pin or stud fixed on the frame or plate of the machine and so communi-
cating to the fancy roller the desired endwise motion.
Such being the nature and object of my invention, the following is a complete
description of same reference being had to the accompanying drawings in which :-
Fig. 1 is an end elevation of a fancy roller fitted with apparatus for imparting.
an endwise or to and fro traverse to it.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is a plan view of the underside of the toothed wheel shewing the eccentric
thereon.
Fig. 4 is a side elevation of Fig. 3.
Fig. 5 is a plan view of the strap for enclosing the eccentric and the crank or arm
attached to such strap.
According to this invention in order to impart to the fancy roller an endwise
reciprocating, or to and fro traverse motion in addition to the ordinary rotary
motion I employ appliances as follows: -The axis of the fancy roller 1 is mounted
in bearings such as 2 in the ordinary manner and is driven or caused to rotate as
usual by means of driving strap and pullies not shewn in the drawings, being at the
opposite side of the machine to that illustrated, and the axis 3 of the fancy roller 1
is slightly longer than usual and fixed thereon is the worm 4 gearing with and
driving a worm wheel 5 the boss 6 of which forms an eccentric to the centre of such
wheel 5 and this eccentric 6 is enclosed by a metal strap 7 an arm or crank 8 cast
to the latter being carried and free to move on the fulcrum stud or pin 9 fixed to
the side frame 10 of the machine.
The worm wheel and its eccentric 6 are carried on a pin or bolt 11 the latter
being fixed by collar or flange 12 and nut 13 to the bracket 14 the ears or lugs 15. 15
of which have holes formed through them for the passage of the axis 3 of the
roller 1 and one of such lugs 15. 15 is on each side of and close to the worm 4.
The action is as follows:-When the fancy roller 1 is caused to rotate in the
ordinary manner the worm 4 also rotates and imparts motion to the worm wheel 5
and the pin or bolt 11 carrying the latter is by the eccentric 6 alternately moved
towards or from the fixed stud or pin 9 at the same time moving with it the
bracket 14 the ears or lugs 15. 15 of which bearing against one or other side of the
worm 4 give the required endwise traverse to the fancy roller 1. By reason of
the arm or crank 8 being mounted loosely on its pin or stud 9 the bracket 14
receives only the motion above described, and is not moved laterally so as to cause
any strain on the parts. 16 is a bracket or support fixed to the side frame 10 of
the machine for supporting the pin or bolt 11 the lower end of same resting and
moving or sliding thereon."
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improved means and apparatus herein described and illustrated by annexed
drawings for purpose herein set forth.
