PROVISIONAL SPECIFICATION.
Improvements in Scribbling or Carding Machines.
We, BENJAMIN BOOTH of Rock Terrace, Berry Brow near Huddersfield York-
shire, Scribbling Engineer, and JOSHUA BEAUMONT of Robin Hood Hill, Berry
Brow aforesaid, Scribbling Engineer, do hereby declare the nature of this invention
to be as follows: -
This invention refers to scribbling or carding engines for carding wool and like
fibres and our improvements consist of means or a combination of means for
considerably increasing the working surface of the cylinder or cylinders or swifts
whereby much more work can be done with less waste than previously and a finer
better and stronger yarn produced.
For the purpose of our invention we combine with the swift or cylinder or with
each swift or cylinder two separate and distinct endless chains of card flats or
sheets of cards which are arranged to work in conjunction with the upper surface
of the cylinder on opposite sides of the axial line thereof and which dispense with
some of the rollers or workers now employed. We use the ordinary "licker in"
and angle stripper and above the latter we place the first endless sheet of cards or
card flats which is arranged to work over a short section of the cylinder, the fibre
being removed from the card flats and given to the cylinder by a stripper, whilst
a fancy raises the fibre on the cylinder preparatory to reaching the second endless
sheet of cards or card flats working over another section of the cylinder. In the
case of the latter the fibre removed from the cylinder is carried completely around
by the flats and just before reaching the cylinder again is stripped and given to the
said cylinder by a stripper, after which it again passes between the cylinder and
second endless sheet of cards, some fibres naturally being taken round by the flats
a second time or more along with fresh fibres and other fibres going forward to
a fancy which raises them on the cylinder ready for removal by the doffer.
By the above means we obtain, in addition to the increased working surface of
the first endless sheet of cards, (which in itself is not sufficient to give good results)
a further increased working surface on a second section of the cylinder which
further acts upon the fibres after they have passed beyond the first card flats, and
in carrying the fibres round and stripping them off the second endless sheet
at the front thereof they mix with the other fibres being carried forward by the
cylinder and again pass between the working surfaces, those fibres not taken up
by the card flats being carried forward to the point of delivery. The fibres are
thus more evenly and completely carded or lashed out and produce a much finer
and superior yarn with less waste than heretofore.
The endless sheets or chains preferably travel round three rollers one of each set
being arranged at such an angle as to enable the strippers to remove the fibre and
give it to the cylinder; or two rollers one a stripper and the other a receiving
roller in conjunction with each endless sheet.
The parts are driven by any of the ordinary and well known means.

We, BENJAMIN BOOTH, of Rock Terrace, Berry Brow, near Huddersfield, York-
shire, Scribbling Engineer, and JOSHUA BEAUMONT, of Robin Hood Hill, Berry
Brow, aforesaid, Scribbling Engineer, 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:—
This invention refers to scribbling or carding machines for carding wool and
like fibres and our improvements consist of the application and employment, in
combination with the main swift or cylinder, or each swift or cylinder, of a
scribbling or carding machine, of two or more separate and distinct endless chains
of card flats or endless cards which considerably increase the working surface on
the cylinder or swift and admit of much more work being done with less waste
than previously and a finer better and stronger yarn produced.
For the purpose of fully describing and ascertaining our said Invention we here-
after make reference to the drawings annexed hereto, and forming a part of this
Specification, whereon is shewn a side elevation of part of a carding machine
having our improvements applied.
Referring to the drawings, letter A represents the swift or main cylinder of a
carding machine with which we combine two separate and distinct chains of card
covered flats or endless cards B, and C, arranged to work in conjunction with the
upper surface of the cylinder A on each side of the axial line thereof and which
dispense with many of ordinary card covered rollers and "workers" now
employed.
Each chain of card flats or endless card, travels around a set of three rollers, the
centres of two rollers in each set being concentric with the cylinder A and the
third roller of each set being placed at an angle above the others so as to cause
the chains of flats or endless cards to travel in a straight line at the point where
the fibre is to be removed therefrom. This arrangement enables the fibre to be
removed from the flats and laid direct on to the cylinder A. by strippers D and E,
respectively acting in conjunction with the chains of flats B and C.
We may, however, if required, employ small card rollers or receivers and place
one intermediate of each stripper D and E and the cylinder A to take the fibre
from the said strippers and lay it on the cylinder.
The chains of card flats are driven at approximately the same speed as the rollers
or workers, whose place they take, by means of suitable wrapping connections or
gear from any rotating part of the machine, it only being necessary to drive one
of the rollers in each set which is preferably, the lower one.
Above the ordinary "licker in" and "angle stripper" (not shewn) or following
same we place the first endless chain of card flats B which works over a section
of the cylinder A and cards or lashes out the fibre carried by said cylinder into the
teeth of the flats which are travelling at a slower speed than the cylinder.
The fibre is removed from the card flats and given back to the cylinder by the
stripper D, a fancy F subsequently raising the fibre out of the teeth of the
cylinder preparatory to reaching the second endless sheet of cards or card flats C
working over another section of the cylinder A. In the case of this second endless
card C, the fibre removed thereby from the cylinder is carried completely around
by the flats and just before reaching the cylinder again, is stripped off same and
given to the cylinder by the stripper E after which it again passes between the
cylinder and endless card C, some fibres naturally being taken round by the flats
a second time, or more, along with fresh fibres and mix with other fibres going

page_text: forward to the fancy G, which raises them on the cylinder ready for removal by
the "doffer" H.
By the above means, in addition to the increased working surface of the first
endless sheet of cards B (which in itself, is not sufficient, to give the good results
desired), we obtain a further increased working surface on a second section of the
cylinder which further acts upon the fibres after they have passed beyond the first
endless card B, and in carrying the fibres round and stripping them off the second
endless sheet C at the front end thereof they are mixed with fresh fibres being
carried forward by the cylinder and again pass between the working surfaces,
those fibres not taken up by the card flats being carried forward by the cylinder
to the point of delivery.
The fibres are thus more evenly and completely carded or lashed out and produce--
a much finer and superior yarn with less waste than heretofore.
It will be understood that if the fibre is not required to be carried a second or
more times between the endless card C and the cylinder, the stripper E can be
placed at the opposite side of the card C and the third or upper roller of the set of
rollers around which the chain of card flats travels, be likewise brought to the same
side to give a straight traverse thereof.
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:-
-
Firstly. In carding and scribbling machines, the combination, with the main
swift or cylinder, or cylinders, of two or more chains of card covered flats or endless
cards acting in conjunction therewith in the manner substantially as described and
shewn in the drawings.
Secondly. In carding and scribbling machines, the combination, with the
cylinders, of two chains of carl covered flats or endless cards such as B and C,
and strippers D and E, all arranged and acting in the manner and for the purposes
substantially as herein shewn and described.
