LETTERS PATENT to Albert Barker, of Leeds, in the County of York,
for an Invention of IMPROVEMENTS IN SCRIBBLING AND CARDING
MACHINERY."
PROVISIONAL SPECIFICATION left by the said Albert Barker at the Office
of the Commissioners of Patents on the 2nd July 1881.

SCRIBBLING AND CARDING MACHINERY."
"IMPROVEMENTS IN
The object of my improvements is to separate the slivers as they are taken off
the condenser doffer, and to prevent them coming together again as they are being
conducted forward to the rubber sheets. And for this purpose I provide flanges
or dises on the stripper corresponding in number with the spaces between the card
rings on the doffer, and projected such a distance from the stripper as to work or
run within such spaces; these flanges or discs separate the slivers as they are taken
from the doffer by the stripper so completely, and retain such separation that they
cannot come together again.
The gutta percha or other packing which is usually employed between the card
rings on the doffer is dispensed with in my improvements. I employ apparatus
for "licking" or clearing out the dirt or other material, which passes into the
space between the card rings of the doffer, so that they may be free to receive the
flanges or discs applied to the stripper.
Instead of the revolving dises or flanges on the stripper, knives, flanges, or other
projecting pieces separate therefrom, or independent thereof may be used in front
of the stripper for the above mentioned purpose.

"IMPROVEMENTS IN
The object of my improvements is to separate the slivers as they are taken off
the condenser doffer, and to prevent them coming together again as they are being

page_text: conducted forward to the rubber shects. And for this purpose provide flanges
or discs on the stripper corresponding in number with the spaces between the card
rings on the doffer, and projected such a distance from the stripper as to work or
run within such spaces; these flanges or discs separate the slivers as they are taken
from the doffer by the stripper so completely and retain such separation that they
cannot come together again.
The gutta percha or other packing which is usually employed between the card
rings on the doffer is dispensed with in my improvements. I employ apparatus
for " licking" or clearing out the dirt or other material which passes into the space
between the card rings of the doffer, so that they may be free to receive the flanges
or discs applied to the stripper.
Instead of the revolving discs or flanges on the stripper, knives, flanges, or other
projecting pieces separate therefrom or independent thereof, may be used in front
of the stripper for the above mentioned purpose.
And in order that my Invention may be more completely understood, reference
is given to the accompanying Drawings, and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a part longitudinal elevation, and Fig. 2 an end elevation shewing my
improvements.
a represents a portion of doffer; b, the flanges or discs which correspond in
number with the spaces c between the card rings d on the doffer a; these discs or
flanges are mounted on the stripper shaft c, and project by reason of their larger
diameter such a distance from the stripper as to run within the spaces c to the
depth of the carding on the doffer. The discs or flanges b by revolving with the
stripper separate the slivers as they are taken from the doffer a, and retain that
separation so completely that they cannot come together again. During the working
of this apparatus it is necessary that the dirt or other material which has a
tendency to accummulate in the spaces c should be prevented in order to secure the
perfect working of the discs b. For this purpose I serrate or indent the periphery
of each disc or flange b, by preference saw like, as shown at f; by such means all
accummulation is prevented.
The gutta percha or other packing which is usually employed between the card
rings on the doffer is dispensed with.
I would further remark that instead of the discs or flanges b being mounted on
the stripper shaft e they may be mounted on a separate or independant shaft
mounted in suitable bearings on the framework in front of the stripper.
Having now described the nature of the said Invention, and particularized the
same by details which answer well in practice, I would have it understood that I
do not confine myself to the exact details set forth; what I do claim is,-
The arrangement, construction, and application of flanges or discs b, substantially
as and for purposes herein set forth.
In witness whereof, I, the said Albert Barker, have hereunto set my hand
and seal, this Thirtieth day of December, in the year of our Lord One
thousand eight hundred and eighty-one.
ALBERT BARKER. (L.S.)
