page_text: We, PATRICK KELLY, of Sutton Mills, Kildwick, in the County of York,
Managing Overlooker, and JONAS HALEY, of Pyenot Hall Mills, Cleckheaton, in
the County aforesaid, Card Maker, do hereby declare the nature of this invention
to be as follows: ---
This invention relates to gill boxes for gilling and straightening fibres and
comprises improvements in the fallers and in the screws or worms employed for
traversing said gill bars, and in the taking off apparatus, the latter being designed
to effect a breaking or crushing of burs or like impurities that may be amongst
the fibres.
According to this invention whatever the number of gill bars to be employed
in one box the said bars are divided into two sets or series and each set or series
has its own operating screw or worm, the latter being of such pitch as to impart
a different speed or traverse to its own set or series of gill bars, and each set
has its own faller and lifting motion.
The screws or worms at each side of the box comprise a single cut screw of
say about 8 inch pitch, and also a double cut screw of about 3/4 inch pitch, and
both of which screws are mounted end to end on one shaft or axis, the first series
of gill bars being operated by the finer pitch screw, whilst the second series of
gill bars being operated by the coarser pitch screw receive a relatively quicker
motion so that the gill pins thereof make a relatively greater traverse or motion
in and amongst the fibre so as to gill, lash, and straighten the fibres whilst practi-
cally held by the slower moving gills of the first series of gill bars.
In order to provide for the strain put upon the first series of gills through the
strain on the fibres occasioned by the quicker motion of the second series of gill
bars, the bars of the first series are made wider and the ends of each of the first
series are cut away or hollowed out so as to admit of the cam for putting down
the first series of gill bars making two revolutions for each bar put down, as the
cam makes one idle revolution opposite the recess or spaced out end of the bars,
the object of such idle revolution is to time the fall of the bars in the two series,
i.e., the second series falls four bars to one bar falling in the first series.
Ás above stated at each side of the box both screws are on one axis and the
finer screw is constructed on a long collar and a locking key with screw adjustment
whereby the screws and bars can be adjusted at relative distances as required.
When the fibre is drawn off the gills it passes between fluted rollers, leather
covered, thence over a fluted leather covered roller or drum on which are two or
more other fluted rollers, leather covered, so that the fibre whilst in the form of an
opened sliver is subjected to a pressing or rolling action of the several rollers so
as to crush and break up the burs or like impurities in the fibres. The leather
coverings consist of endless sheets or belts of leather running over the rollers
referred to, and over guide and stretching rollers.

falling in the first series 1.
As above stated, at each side of the box both screws 2, 2ª are on one axis 3 and
the finer screw 2 is constructed on a long collar 6, and after being slided on the
locking key 7 is fixed by the collar nuts 8 screwed onto the shaft 3, whereby the
screws 2 and bars 1 can be adjusted at correct relative distances from the screws 2"
and bars 1 as required. The top screw of each pair is made half the pitch of the
bottom one (see Fig. 1) and two bars or fallers are carried on the reverse traverse
at the same time.
When the fibre is drawn off the gills it passes between fluted leather covered
rollers 9, 9, thence over a fluted leather covered roller or drum 10 on which are
two or more fluted rollers 11, 11 also leather covered, so that the fibre whilst in
the form of an opened sliver is subjected to a pressing or rolling action of the
several rollers so as to crush and break up the burrs or like impurities in the fibres,
the leather covering preventing the fibre being cut or damaged. The leather
coverings consist of endless sheets or belts of leather 12, 12 running over the
several rollers referred to, and over guide and stretching rollers 13 adjustable in
their carrying frames 14, 14.
The machine and method of operating and controlling the gill bars or fallers 1, 1ª
and the screws 2, 2" is as ordinary.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we would have it understood
that we lay no claim to the gill bars in two series having independant speeds
of traverse, per se, but what we claim is:-
-
(1). The general construction, arrangement, and combination of parts consti-
tuting the improvements in gill boxes, as and for the purpose herein described and
substantially as illustrated by the annexed drawings.
(2). The screws or worms 2, 2ª of different pitch and imparting to their gill
bars or fallers 1, 1 different speeds of traverse the fallers 1 having cut away or
hollowed ends all in combination as and for the purpose herein described and
substantially as illustrated by Figs. 1 and 2 of the annexed drawings.
(3). The screws or worms 2, 2, gill bars or fallers 1, 1ª, and leather covered
rollers, all in combination as and for the purpose herein described and substan-
tially as illustrated by the annexed drawings.
