Year: 1878

page_text: LETTERS PATENT to Eli Wilkinson, of Marsden, near Huddersfield, in the
County of York, for the Invention of "IMPROVEMENTS IN APPARATUS TO BE
EMPLOYED IN MACHINERY FOR SCRIBBLING AND CARDING WOOL AND OTHER
FIBROUS SUBSTANCES."
Sealed the 15th April 1879, and dated the 16th October 1878.
PROVISIONAL SPECIFICATION left by the said Eli Wilkinson at the Office
of the Commissioners of Patents on the 16th October 1878.

"IM-
PROVEMENTS IN APPARATUS TO BE EMPLOYED IN MACHINERY FOR SCRIBBLING AND
CARDING WOOL AND OTHER FIBROUS SUBSTANCES."
This Invention relates to improved apparatus to be employed for stripping and
cleaning the workers, doffers, and swifts of scribbling and carding machinery instead
of the rollers covered with card teeth at present in use for that purpose.
As a substitute for wire cards I employ rows of teeth or reeds made of flat
hardened and tempered steel, each tooth consisting of a separate strip or reed of
steel, and being woven into wood laths or lags in a similar manner to the reeds
employed in looms for weaving, with this difference, namely, that only one end of the
reed is woven into the lags, the other end being pointed for the purpose of acting
on the material.
Rows of teeth or reeds thus connected together are attached to the periphery of
a roller or central axis at intervals in a line parallel to the said axis, and may be
used for the purpose of stripping the wool from the "workers" and "doffers; " the

page_text: teeth or reeds enter the cards and prevent the short fibres from remaining therein,
thus bringing out all the material and dispensing with a great amount of hand
labour in cleaning the cards.
In addition to the above purposes, these rows of teeth or reeds may be applied
advantageously to the "fancy" rollers, one or two rows being sufficient to prevent
the formation of what is called "shoddy."
Rows of teeth or reeds constructed as above described may be readily attached
to the cylinder or axis by any ordinary workman, the cylinder being grooved for
the reception of the lags, but in some cases it is preferable to have the rows of teeth
or reeds fixed to wings or blades attached to the axis, slots being formed therein for
adjusting the same as the points wear away.

the said Eli Wilkinson in the Great Seal Patent Office on the 16th April

ELI WILKINSON, of Marsden, near Huddersfield, in the County of York. "Iм-
PROVEMENTS IN APPARATUS TO BE EMPLOYED IN MACHINERY FOR SCRIBBLING AND
CARDING WOOL AND OTHER FIBROUS SUBSTANCES."
This Invention relates to apparatus to be employed for stripping and cleaning the
workers, doffers, and swifts of scribbling and carding machinery instead of the rollers
covered with card teeth at present in use for that purpose.
As a substitute for wire cards I employ rows of teeth or reeds made of flat
hardened and tempered steel, each tooth consisting of a separate strip or reed of
steel, and being woven into wood laths or lags in a similar manner to the reeds
employed in looms for weaving, with this difference, namely, that only one end of
the reed is woven into the lags, the other end being pointed for the purpose of acting
on the material.
In the Drawings accompanying this Specification these rows of reeds or teeth are
represented by A, the wood laths or lags being lettered B.
"
Although it is immaterial how the said teeth or reeds may be set in or secured
side by side in the "lags or foundation, I have found it convenient to weave the
flattened wire into the lags in the first instance, so as to form an entire reed such as
is employed in looms for weaving. This entire reed is then cut in two, by which
the teeth or dents are divided equally, leaving two rows of teeth of equal length.
This explanation will be understood on reference to Fig. 7, in which C is an emery
wheel so formed that the edge cuts the teeth and leaves the two parts pointed to
the required angle.
In Fig. 4 I have shewn skeleton of machine or apparatus for communicating the
requisite revolving and traversing motion of the wheel, which is mounted on a
sliding bracket drawn to and fro by chain or belt D, whilst an endless band E
passing over guide pulleys gives the revolving motion. Rows of teeth or reeds
thus constructed may be attached to the periphery of a roller or central axis at
intervals in a line parallel to the said axis, and may be used for the purpose of
stripping the wool from the "workers" and "doffers;" the teeth or reeds enter
the cards and prevent the short fibres from remaining therein, thus bringing out all
the material and dispensing with a great amount of hand labour in cleaning the
cards.
In Fig. 1 I have shewn such a stripper," in which the rows of teeth are inserted
into channels G formed in a cylinder or polygon. The reeds rest upon slips of
wood H (which are first inserted into the channels), and are then packed by wedges
J, the whole being secured by metal plates K fastened to the sides of the cylinder
by screws L. As the points wear away and the teeth become shorter, packing may
be placed underneath the slips H, so as to cause the points of the teeth to project.
the requisite distance from the surface of the cylinder, and this operation may be
repeated until the teeth are too short to be of any service.
In Fig. 2 I have shewn a method in which two rows of teeth or reeds may be
applied advantageously to a "fancy," this number being sufficient to prevent the
formation of "shoddy" or dirt in the cylinder on which the fancy is acting. The
ordinary card teeth are applied in separate sheets nailed or otherwise secured to the
cylinder at the points a, and as the clothing or leather becomes slack strips of wood
may be placed across the cylinder, and forced or screwed down into the grooves c,
so as to tighten the leather, thus doing away with the necessity of renailing the
cards on the fancy.
In Figs. 5 and 6 I have shewn a stripper and " fancy," in which the rows of teeth
are inserted into grooves sufficiently deep to receive the lags B, which are secured
by means of plates M screwed to the cylinder. This method of fixing is very simple,

page_text: as by slackening the screws slightly one row of teeth may be drawn out laterally
and another inserted in its place. When the rows of teeth are worn away so much
as to be unfit for "fancies," they will be useful for small strippers to strip
the 'workers," which require shorter teeth, so that there will be very little
"
waste.
It will be readily seen that specially constructed cylinders are not required in
carrying out my Invention, as ordinary cylinders may be utilized with very little
trouble.
The teeth or reeds herein referred to can be advantageously used in place of the
ordinary reciprocating doffing comb for stripping the wool or other fibre off the last
doffer of a scribbling and carding machine. A roller constructed somewhat similar
to the one shewn in Fig. 5 of the accompanying Drawings may be employed to
revolve in contact with the last doffer and strip the wool therefrom. Or a separate
row of teeth or reeds may be fastened on to the ordinary doffing stock or bar, and
employed to strip the wool or other fibre off the doffer instead of the doffing comb
at present in use.
Having thus described the nature of my Invention and the manner in which
the same is to be or may be performed, I would have it understood that I do not
claim the reeds or the weaving of the reeds as of my Invention, but what I do claim
as my Invention is, the application of separate rows of teeth or reeds made of flat
hardened and tempered steel for striping and cleaning all kinds of scribbling and
carding machinery, whether the same be cotton, woollen, or silk machinery, in
manner substantially as herin shewn and described.
In witness whereof, I, the said Eli Wilkinson, have hereunto set my hand and
scal, this Ninth day of April, in the year of our Lord One thousand eight
hundred and seventy-nine.
