We, NICHOLAS WORSLEY, of Baxenden, near Accrington, in the County of
Lancaster, Cotton Spinner and Manufacturer, LOUIS ALFRED PORRITT and ELLIS
SCHOFIELD HOWARTH BARNES, of the firm William Tatham and Company, of
Vulcan Works, Rochdale, in the said County, Machine Makers, do hereby declare
the nature of the said invention to be as follows:-
doffer'
"
Our invention is applicable to engines for carding fibrous materials, having
condensers combined therewith, in which machines the fleece from the
is divided into strips or ribbons which are each gathered together laterally and
passed between two endless leather bands which have a lateral to and fro move-
ment besides a progressive or travelling movement which act to roll each strip,
ribbon or sliver and condense it to the form of a round band or roving or sliver
without twist. And our invention is or may be combined with that type of
condenser carding engine mostly used for cotton or cotton waste, but which
may also be used for other fibrous material.
The doffer in this type of engine is divided so that when the doffing comb strips
the fibre from its card surface, it leaves it in the form of narrow ribbons which
each pass to a V groove in a grooved roller (termed a dividing roller) rotating
in front of the doffer and with its axis parallel thereto.
The grooves cause the ribbons of fleece or fibre to be gathered into the
bottom of the angles of the Vs of the roller, and they then pass between the
endless bands which have a reciprocating lateral movement which condenses
the ribbons of fibre into slivers similar to a roving sliver but without twist, and
they then pass between separating guides which direct them to a bobbin on
which they are wound.
The top roller nearest the doffer for one end of the upper endless rubbing or
condensing bands works nearly close to the periphery of the grooved dividing
roller, and sometimes the ribbons break between the doffer and rubbing or
condensing endless bands, and accumulate in the Vs of the grooved roller, and
the attendant or tenters have to remove these accumulations from the V grooves
of the roller and direct the end of the broken ribbon or sliver to an adjoining
sliver so that it will be taken forward by the condensing endless bands and it
is while doing this that the fingers hands or arms of the tenters, if not careful,
may be drawn in between the periphery of the grooved roller and the surface of
the leather band passing over the roller near it as the surfaces are both moving
in the same direction, and such accidents have frequently happened causing
injury to the tenters.
Our invention consists in placing brackets on the framing on each side of
the engine to hold the ends of a round smooth bar by preference (though it may be of
other suitable section) the surface of this bar coming near without touching the

page_text: surface of the endless band and peripheries of the ✓ grooved roller. This
arrangement prevents the fingers or hands of the tenters from being caught and
taken in between the two adjoining surfaces moving in the same direction, and
helps to direct a broken ribbon of sliver to pass between the endless rubbing
belts or condensers. The bar can be readily removed and replaced when
required.

We, NICHOLAS WORSLEY, of Baxenden, near Accrington, in the County of
Lancaster, Cotton Spinner and Manufacturer, LOUIS ALFRED PORRITT and ELLIS
SCHOFIELD HOWARTI BARNES, of the firm William Tatham and Company, of
Vulcan Works, Rochdale, in the said County, Machine Makers, 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: --
Our invention is applicable to engines for carding fibrous materials, having
condensers combined therewith, in which machines the fleece from the
doffer
is divided into strips or ribbons which are each gathered together laterally and
passed between two endless leather bands which have a lateral to and fro move-
ment besides a progressive or travelling movement, which act to roll each strip,
ribbon or sliver and condense it to the form of a round band or roving or sliver
without twist. And our invention is or may be combined with that type of
condenser carding engine mostly used for cotton or cotton waste, but which
may also be used for other fibrous material.
The doffer in this type of engine is divided so that when the doffing comb strips
the fibre from its card surface, it leaves it in the form of narrow ribbons which
each pass to a V groove in a grooved roller (termed a dividing roller) rotating
in front of the doffer and with its axis parallel thereto.
The grooves cause the ribbons of fleece or fibre to be gathered into the
bottom of the angles of the V's of the roller, and they then pass between the
endless bands which have a reciprocating lateral movement which condenses
the ribbons of fibre into slivers similar to a roving sliver but without twist, and
they then pass between separating guides which direct them to a bobbin on
which they are wound.
The top roller nearest the doffer for one end of the upper endless rubbing or
condensing bands works nearly close to the periphery of the grooved dividing
roller, and sometimes the ribbons break between the doffer and rubbing or
condensing endless bands, and accumulate in the V's of the grooved roller, and
the attendant or tenters have to remove these accumulations from the V grooves
of the roller and direct the end of the broken ribbon or sliver to an adjoining
sliver so that it will be taken forward by the condensing endless bands and it
is while doing this that the fingers hands or arms of the tenters, if not careful,
may be drawn in between the periphery of the grooved roller and the surface of
the leather band passing over the roller near it as the surfaces are both moving
in the same direction, and such accidents have frequently happened causing
injury to the tenters.

page_text: Our invention consists in placing brackets on the framing on each side of
the engine to hold the ends of a round smooth bar by preference (though it may be of
other suitable section) the surface of this bar coming near without touching the
surface of the endless band and peripheries of the V grooved roller. This
arrangement prevents the fingers or hands of the tenters from being caught and
taken in between the two adjoining surfaces moving in the same direction, and
helps to direct a broken ribbon of sliver to pass between the endless rubbing
belts or condensers. The bar can be readily removed and replaced when
required.
Fig. 1, is a side elevation, and
Fig. 2, a plan of so much of the mechanism of a condensing carding engine as
will be necessary for clearly illustrating our invention.
a, represents the doffer; a', the oscillating doffer comb; b, V grooved dividing
roller; c, upper endless rubbing band that works over rollers c and c²; ³, lower
endless band that works over rollers and
d, vertical pins in a bar d', between which the slivers pass to wind on to the
bobbin e, which rests upon and is rotated by the drum or cylinder e¹.
, is a roller pressing the lower side of the upper endless band c, downward,
and, a roller to press the upper side of the lower endless band upward, so that
the outer sides of the two endless bands will be kept working close together.
The arrow on the dividing roller b, and that near the roller c, show that the
surfaces of the roller b, and endless bands c, opposite each other are moving in
the same direction and will act to draw in between them anything coming
sufficiently near them, so as to be caught by their surfaces, hence the danger to
the attendants when they have to take an accumulation of the ribbon of carded
material from the V grooved roller b, and attach it to an adjoining ribbon or
sliver.
According to our invention we place. brackets ¹, on each side frame, to
carry the ends of a round smooth rod or roller f, by preference, the surface of
which comes near, but without touching the large periphery of the V roller b,
and the surface of the endless band or bands c, as they pass over the roller c¹.
The bar or rod can be readily removed and replaced when required.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The combination of a rod, roller bar or its equivalent with condensing carding
engines placed near the dividing roller, substantially as and for the purpose
hereinbefore described and illustrated by the drawings.
